[00126] [00126] Figure 3 represents an example of a surgical system 102 being used to perform a surgical procedure on a patient who is lying on an operating table 114 in a surgical operating room 116. A robotic system 110 is used in surgical procedure as a part of the surgical system 102. The rotary system 110 includes a surgeon console 118, a patient car 120 (surgical robot), and a robotic central surgical controller 122. The patient car 120 can handle at least one surgical tool removably coupled 117 through a minimally invasive incision in the patient's body while the surgeon views the surgical site through the surgeon's console 118. An image of the surgical site can be obtained by a medical imaging device 124, which can be manipulated by the patient's carriage 120 to guide the imaging device 124. The robotic central controller 122 can be used to process the patient's images. surgical site for subsequent display to the surgeon through the surgeon's console 118.
[00127] [00127] Other types of robotic systems can be readily adapted for use with the surgical system 102. Various examples of robotic systems and surgical instruments that are suitable for use with the present description are described in provisional patent application no. 62 / 611,339, entitled ROBOT ASSISTED SURGICAL PLATFORM, filed on December 28, 2017, whose description is hereby incorporated by reference in its entirety for reference.
[00128] [00128] Several examples of cloud-based analysis that are performed by cloud 104, and are suitable for use with the present description, are described in US Provisional Patent Application Serial No. 62 / 611.340, entitled CLOUD-BASED MEDICAL ANALYTICS , deposited on December 28, 2017, the description of which is incorporated herein by reference, in its entirety.
[00129] [00129] In several aspects, the imaging device 124 includes at least one Image sensor and one or more optical components. Suitable image sensors include, but are not limited to, load-coupled device (CCD) sensors and complementary metal oxide semiconductor (CMOS) sensors.
[00130] [00130] The optical components of the imaging device 124 may include one or more light sources and / or one or more lenses. One or more light sources can be targeted to illuminate portions of the surgical field. The one or more image sensors can receive reflected or refracted light from the surgical field, including reflected or refracted light from the tissue and / or surgical instruments.
[00131] [00131] One or more light sources can be configured to radiate electromagnetic energy in the visible spectrum, as well as in the invisible spectrum. The visible spectrum, sometimes called the optical spectrum or light spectrum, is that portion of the electromagnetic spectrum that is visible to (that is, can be detected by) the human eye and can be called visible light or simply light. A typical human eye will respond to wavelengths in the air that are from about 380 nm to about 750 nm.
[00132] [00132] The invisible spectrum (that is, the non-luminous spectrum) is that portion of the electromagnetic spectrum located below and above the visible spectrum (that is, wavelengths below about 380 nm and above about 750 nm). The invisible spectrum is not detectable by the human eye. Wavelengths greater than about 750 nm are longer than the visible red spectrum, and they become invisible infrared (IR), microwave, radio and electromagnetic radiation. Wavelengths shorter than about 380 nm are shorter than the ultraviolet spectrum, and they become invisible ultraviolet, x-ray, and gamma-ray electromagnetic radiation.
[00133] [00133] In several aspects, the imaging device 124 is configured for use in a minimally invasive procedure. Examples of imaging devices suitable for use with the present description include, but are not limited to, an arthroscope, angioscope, bronchoscope, choledocoscope, colonoscope, cytoscope, duodenoscope, enteroscope, esophagus-duodenoscope (gastroscope), endoscope, laryngoscope, nasopharyngoscope neproscope, sigmoidoscope, thoracoscope, and ureteroscope.
[00134] [00134] In one aspect, the imaging device employs multiple spectrum monitoring to discriminate topography and underlying structures. A multi-spectral image is one that captures image data within wavelength bands across the electromagnetic spectrum. The wavelengths can be separated by filters or by using instruments that are sensitive to specific wavelengths, including light from frequencies beyond the visible light range, for example, IR and ultraviolet light. Spectral images can allow the extraction of additional information that the human eye cannot capture with its receivers for the colors red, green, and blue. The use of multi-spectral imaging is described in more detail under the heading "Advanced Imaging Acquisition Module" in US Provisional Patent Application Serial No. 62 / 611,341, entitled INTERACTIVE SURGICAL PLATFORM, filed on December 28, 2017, whose description is incorporated here as a reference in its entirety. Multispectral monitoring can be a useful tool for relocating a surgical field after a surgical task is completed to perform one or more of the tests previously described on the treated tissue.
[00135] [00135] It is axiomatic that strict sterilization of the operating room and surgical equipment is necessary during any surgery. The strict hygiene and sterilization conditions required in an "operating room", that is, an operating or treatment room, justify the highest possible sterilization of all medical devices and equipment. Part of this sterilization process is the need to sterilize anything that comes into contact with the patient or enters the sterile field, including imaging device 124 and its connectors and components. It will be understood that the sterile field can be considered a specified area, such as inside a tray or on a sterile towel, which is considered free of microorganisms, or the sterile field can be considered an area, immediately around a patient, who was prepared to perform a surgical procedure. The sterile field may include members of the brushing team, who are properly dressed, and all furniture and accessories in the area.
[00136] [00136] In various aspects, the visualization system 108 includes one or more imaging sensors, one or more image processing units, one or more storage arrays and one or more screens that are strategically arranged in relation to the field sterile, as shown in Figure 2. In one aspect, the visualization system 108 includes an interface for HL7, PACS and EMR. Various components of the visualization system 108 are described under the heading "Advanced Imaging Acquisition Module" in US Provisional Patent Application Serial No. 62 / 611,341, entitled INTERACTIVE SURGICAL PLATFORM, filed December 28, 2017, the description of which is here incorporated by reference in its entirety.
[00137] [00137] As shown in Figure 2, a primary screen 119 is positioned in the sterile field to be visible to the operator on operating table 114. In addition, a viewing tower 111 is
[00138] [00138] In one aspect, the central controller 106 is also configured to route an input or diagnostic feedback by a non-sterile operator in the viewing tower 111 to the primary screen 119 within the sterile field, where it can be seen by a sterile operator on the operating table. In one example, the input may be in the form of a modification of the snapshot displayed on the non-sterile screen 107 or 109, which can be routed to the main screen 119 by the central controller 106.
[00139] [00139] With reference to Figure 2, a surgical instrument 112 is being used in the surgical procedure as part of the surgical system 102. The central controller 106 is also configured to coordinate the flow of information to a screen of the surgical instrument 112. For For example, in US Provisional Patent Application Serial No. 62 / 611,341, entitled INTERACTIVE SURGICAL PLATFORM, filed on December 28, 2017, the description of which is hereby incorporated by reference in its entirety for reference. A diagnostic input or re-information inserted by a non-sterile operator in the viewing tower 111 can be routed by the central controller 106 to the screen of the surgical instrument 115 in the sterile field, where it can be seen by the operator of the surgical instrument 112. Surgical instruments Other examples that are suitable for use with surgical system 102 are described under the title "Surgical Instrument Hardware" and in provisional patent application serial number 62 / 611,341, entitled INTERACTIVE SURGICAL PLATFORM, filed on December 28 2017, the description of which is incorporated here for reference in its entirety, for example.
[00140] [00140] Now with reference to Figure 3, a central controller 106 is shown in communication with a visualization system 108, a robotic system 110 and an intelligent hand-held surgical instrument 112. The central controller 106 includes a central controller screen 135, an imaging module 138, a generator module 140, a communication module 130, a processor module 132 and a storage matrix 134. In certain respects, as shown in Figure 3, the central controller 106 additionally includes a module smoke evacuation system 126 and / or a suction / irrigation module 128.
[00141] [00141] During a surgical procedure, the application of energy to the tissue, for sealing and / or cutting, is generally associated with the evacuation of smoke, suction of excess fluid and / or irrigation of the tissue. Fluid, power, and / or data lines from different sources are often intertwined during the surgical procedure. Valuable time can be wasted in addressing this issue during a surgical procedure. To untangle the lines, it may be necessary to disconnect the lines from their respective modules, which may require a restart of the modules. The modular compartment of central controller 136 offers a unified environment for managing power, data and fluid lines, which reduces the frequency of interlacing between such lines.
[00142] [00142] The aspects of the present description present a central surgical controller for use in a surgical procedure that involves the application of energy to the tissue at a surgical site. The central surgical controller includes a central controller compartment and a combined generator module received slidingly at a central controller compartment docking station. The docking station includes data and power contacts. The combined generator module includes two or more of an ultrasonic energy generating component, a bipolar RF energy generating component, and a monopolar RF energy generating component which are housed in a single unit. In one aspect, the combined generator module also includes a smoke evacuation component, at least one power application cable to connect the combined generator module to a surgical instrument, at least one smoke evacuation component. configured to evacuate smoke, fluid, and / or particulates generated by the application of therapeutic energy to the tissue, and a fluid line that extends from the remote surgical site to the smoke evacuation component.
[00143] [00143] In one aspect, the fluid line is a first fluid line and a second fluid line extends from the remote surgical site to a suction and irrigation module received slidingly into the central controller compartment. In one aspect, the central controller compartment comprises a fluid interface.
[00144] [00144] Certain surgical procedures may require the application of more than one type of energy to the tissue. One type of energy may be more beneficial for cutting the fabric, while another type of energy may be more beneficial for sealing the fabric. For example, a bipolar generator can be used to seal the tissue while an ultrasonic generator can be used to cut the sealed tissue. Aspect-
[00145] [00145] Aspects of the present description present a modular surgical compartment for use in a surgical procedure that involves applying energy to the tissue. The modular surgical compartment includes a first energy generator module, configured to generate a first energy for application to the tissue, and a first docking station that comprises a first coupling port that includes first data contacts and energy contacts , the first power generator module being slidably movable in an electric coupling with the power and data contacts, and the first power generator module is slidingly movable out of the electric coupling with the first power and data contacts.
[00146] [00146] In addition to the above, the modular surgical compartment also includes a second energy generator module configured to generate a second energy, different from the first energy, for application to the tissue, and a second docking station comprising a second coupling port that includes second data and power contacts, the second power generator module being slidably movable in an electrical coupling with the power and data contacts, and the second power generator module energy is slidably movable out of the electrical coupling with the second power and data contacts.
[00147] [00147] In addition, the modular surgical compartment also includes a communication bus between the first hospital door
[00148] [00148] With reference to Figures 3 to 7, aspects of the present description are presented for a modular compartment of the central controller 136 that allows the modular integration of a generator module 140, a smoke evacuation module 126, and a suction / irrigation 128. The central modular compartment 136 further facilitates interactive communication between modules 140, 126, 128. As illustrated in Figure 5, generator module 140 can be a generator module with integrated monopoly, bipolar and ultrasonic components , supported in a single cabinet unit 139 slidably insertable in the central modular compartment 136. As shown in Figure 5, generator module 140 can be configured to connect to a monopolar device 146, a bipolar device 147 and an ultrasonic device 148. Alternatively, generator module 140 may comprise a series of monopolar, bipolar and / or ultrasonic generator modules that interact through via the central modular compartment 136. The central modular compartment 136 can be configured to facilitate the insertion of multiple generators and interactive communication between generators anchored in the central modular compartment 136 so that the generators act as a single generator.
[00149] [00149] In one aspect, the central modular compartment 136 comprises a modular power and a rear communication board 149 with external and wireless communication heads to allow the removable fixing of modules 140, 126, 128 and interactive communication between the themselves.
[00150] [00150] In one aspect, the central modular compartment 136 includes docking stations, or drawers, 151, here also called drawers, which are configured to receive modules 140, 126, 128 in a sliding manner. Figure 4 illustrates a view in partial perspective of a central surgical controller compartment 136, and a combined generator module 145 received slidingly in a docking station 151 of the central surgical controller compartment 136. A docking port 152 with power and counter data on a rear side of the combined generator module 145 is configured to engage a corresponding docking port 150 with the power and data contacts of a corresponding docking station 151 of the central controller 136 modular bay as the combined generator module 145 is slid into position at the corresponding docking station 151 of the central controller 136 modular compartment. In one aspect, the module The combined generator 145 includes a bipolar, ultrasonic and monopolar module and a smoke evacuation module integrated in a single compartment unit 139, as shown in Figure 5.
[00151] [00151] In several respects, the smoke evacuation module 126 includes a fluid line 154 that transports fluid captured / collected smoke away from a surgical site and to, for example, the smoke evacuation module 126. The vacuum suction that originates from the smoke evacuation module 126 can pull the smoke into an opening of a utility conduit at the surgical site. The utility conduit, coupled to the fluid line, can be in the form of a flexible tube that ends in the smoke evacuation module 126. The utility conduit and the fluid line define a fluid path that extends across towards the smoke evacuation module 126 which is received in the central controller compartment 136.
[00152] [00152] In several aspects, the suction / irrigation module 128 is coupled to a surgical tool comprising a fluid suction line and a fluid suction line. In one example, the suction and suction fluid lines are in the form of flexible tubes that extend from the surgical site towards the suction / irrigation module 128. One or more drive systems can be configured to cause irrigation and aspiration of fluids to and from the surgical site.
[00153] [00153] In one aspect, the surgical tool includes a drive shaft that has an end actuator at a distal end of it and at least an energy treatment associated with the end actuator, a suction tube, and a irrigation pipe. The suction tube can have an inlet port at a distal end of it and the suction tube extends through the drive shaft. Similarly, an irrigation pipe can extend through the drive shaft and may have an inlet port close to the power application implement. The energy application implement is configured to supply ultrasonic and / or RF energy to the surgical site and is coupled to the generator module 140 by a cable that initially extends through the drive shaft.
[00154] [00154] The irrigation tube can be in fluid communication with a fluid source, and the suction tube can be in fluid communication with a vacuum source. The fluid source and / or the vacuum source can be housed in the suction / irrigation module 128. In one example, the fluid source and / or the vacuum source can be housed in the central controller compartment 136 separately from the suction / irrigation module 128. In such an example, a fluid interface can be configured to connect the suction / irrigation module 128 to the fluid source and / or the vacuum source.
[00155] [00155] In one aspect, modules 140, 126, 128 and / or their corresponding docking stations in the central modular compartment
[00156] [00156] In some respects, the drawers 151 of the central modular compartment 136 are the same, or substantially the same size, and the modules are adjusted in size to be received in the drawers 151. For example, the side brackets 155 and / or 156 can be larger or smaller depending on the size of the module. In other respects, drawers 151 are different in size and are each designed to accommodate a specific module.
[00157] [00157] In addition, the contacts of a specific module can be switched to engage with the contacts of a specific drawer to avoid the insertion of a module in a drawer with unpaired contacts.
[00158] [00158] As shown in Figure 4, the coupling port 150 of a drawer 151 can be coupled to the coupling port 150 of another drawer 151 through a communication link 157 to facilitate interactive communication between the modules housed in the module. central modular compartment 136. The coupling ports 150 of the central modular compartment 136 can, alternatively or additionally, facilitate interactive wireless communication between modules housed in the central modular compartment 136. Any suitable wireless communication can be used, such as, for example, Air Titan Bluetooth.
[00159] [00159] Figure 6 illustrates individual power bus connectors for a plurality of side coupling ports of a lateral modular compartment 160 configured to receive a plurality of modules from a central surgical controller 206. The modular compartment side 160 is configured to receive and later interconnect modules 161. Modules 161 are slidably inserted into docking stations 162 of side modular compartment 160, which includes a back plate for interconnecting modules 161. As shown in Figure 6, modules 161 are arranged laterally in the side modular cabinet 160. Alternatively, modules 161 can be arranged vertically in a modular side cabinet.
[00160] [00160] Figure 7 illustrates a vertical modular cabinet 164 configured to receive a plurality of modules 165 from the central surgical controller 106. Modules 165 are slidably inserted into docking stations, or drawers, 167 of the modular cabinet vertical 164, which includes a rear panel for interconnecting modules 165. Although the drawers 167 of the vertical modular cabinet 164 are arranged vertically, in some cases, a vertical modular cabinet 164 may include drawers that are arranged laterally. In addition, modules 165 can interact with each other through the coupling ports of the vertical modular cabinet
[00161] [00161] In several respects, the imaging module 138 comprises an integrated video processor and a modular light source
[00162] [00162] During a surgical procedure, removing a surgical device from the surgical field and replacing it with another surgical device that includes a different camera or other light source may be inefficient. Temporarily losing sight of the surgical field can lead to undesirable consequences. The imaging device module of the present description is configured to allow the replacement of a light source module or a "midstream" camera module during a surgical procedure, without the need to remove the imaging device from the surgical field.
[00163] [00163] In one aspect, the imaging device comprises a tubular compartment that includes a plurality of channels. A first channel is configured to receive the Camera module in a sliding way, which can be configured for a snap-fit fit (pressure fit) with the first channel. A second channel is configured to slide the camera module, which can be configured for a snap-fit fit (pressure fit) with the first channel. In another example, the camera module and / or the light source module can be rotated to an end position within their respective channels. A threaded coupling can be used instead of a pressure fitting.
[00164] [00164] In several examples, multiple imaging devices are placed in different positions in the surgical field to provide multiple views. Imaging module 138 can be configured to switch between imaging devices to provide an ideal view. In several respects, the imaging module 138 can be configured to integrate images from different imaging devices.
[00165] [00165] Various image processors and imaging devices suitable for use with the present description are described in US Patent No. 7,995,045 entitled COMBINED SBI AND CONVENTIONAL IMAGE PROCESSOR, granted on August 9, 2011 which is here incorporated as a reference in its entirety. In addition, US Patent No. 7,982,776, entitled SBI MOTION ARTIFACT REMOVAL APPARATUS AND METHOD, issued July 19, 2011, which is incorporated herein by reference in its entirety, describes various systems for removing motion artifacts from image data. Such systems can be integrated with imaging module 138. In addition to these, the publication of US Patent Application No. 2011/0306840, entitled CONTROLLA- BLE MAGNETIC SOURCE TO FIXTURE INTRACORPOREAL APPA- RATUS, published on December 15, 2011 , and the publication of US Patent Application No. 2014/0243597, entitled SYSTEM FOR PERFORMING A MINIMALLY INVASIVE SURGICAL PROCEDURE, published on August 28, 2014, which are each incorporated herein by reference in their entirety .
[00166] [00166] Figure 8 illustrates a surgical data network 201 comprising a central modular communication controller 203 configured to connect modular devices located in one or more operating rooms of a health care facility, or any environment in a health care facility specially equipped for surgical operations, to a cloud-based system (for example, cloud 204 which may include a remote server 213 coupled to a storage device 205). In one aspect, the modular communication central controller 203 comprises a central network controller 207 and / or a network key 209 in communication with a network router. The central modular communication controller 203 can also be coupled to a local computer system 210 to provide local computer processing and data manipulation. The surgical data network 201 can be configured as a passive, intelligent, or switching network. A passive surgical data network serves as a conduit for the data, allowing the data to be transmitted from one device (or segment) to another and to cloud computing resources. An intelligent surgical data network includes features to allow traffic to pass through the surgical data network to be monitored and to configure each port on the central network controller 207 or network key 209. An intelligent surgical data network can be called a a central controller or manageable key. A central switching controller reads the destination address of each packet and then forwards the packet to the correct port.
[00167] [00167] Modular devices 1a to 1n located in the operating room can be coupled to the modular central communication controller 203. The central network controller 207 and / or the network key 209 can be coupled to a network router 211 to connect devices 1a to 1n to the 204 cloud or computer system
[00168] [00168] It will be understood that the surgical data network 201 can be expanded by interconnecting multiple central network controllers 207 and / or multiple network keys 209 with multiple network routers 211. The central communication controller 203 can be contained in a modular control tower configured to receive multiple devices 1a to 1n / 2a to 2m. The local computer system 210 can also be contained in a modular control tower. The modular central communication controller 203 is connected to a screen 212 to display the images obtained by some of the devices 1a to 1n / 2a to 2m, for example, during surgical procedures. In several respects, devices 1a to 1n / 2a to 2m can include, for example, several modules such as an imaging module 138 coupled to an endoscope, a generator module 140 coupled to an energy-based surgical device, an evacuation module smoke 126, a suction module
[00169] [00169] In one aspect, the surgical data network 201 may comprise a combination of central network controllers, network switches, and network routers that connect devices 1a to 1n / 2a to 2m to the cloud. Any or all of the devices 1a to 1n / 2a to 2m coupled to the central network controller or network key can collect data in real time and transfer the data to cloud computers for data processing and manipulation. It will be understood that cloud computing depends on sharing computing resources instead of having local servers or personal devices to handle software applications. The word "cloud" can be used as a metaphor for "the Internet", although the term is not limited as such. Consequently, the term "cloud computing" can be used here to refer to "a type of Internet-based computing", in which different services - such as servers, storage, and applications - are applied to the central controller of modular communication 203 and / or computer system 210 located in the operating room (for example, a fixed, mobile, temporary, or operating room or operating space) and devices connected to the central modular communication controller 203 and / or computer system 210 over the Internet. The cloud infrastructure can be maintained by a cloud service provider. In this context, the cloud service provider may be the entity that coordinates the use and control of devices 1a to 1n / 2a to 2m located in one or more operating rooms. Payment services
[00170] [00170] The application of cloud computer data processing techniques to the data collected by devices 1a to 1n / 2a to 2m, the surgical data network provides better surgical results, reduced costs, and better patient satisfaction. At least some of the devices 1a to 1n / 2a to 2m can be used to visualize the states of the tissue to assess the occurrence of leaks or perfusion of sealed tissue after a procedure of sealing and cutting the tissue. At least some of the devices 1a to 1n / 2a to 2m can be used to identify pathology, such as disease effects, with the use of cloud-based computing to examine data including images of body tissue samples for diagnostic purposes . This includes confirmation of the location and margin of the tissue and phenotypes. At least some of the devices 1a to 1n / 2a to 2m can be used to identify anatomical structures of the body using a variety of sensors integrated with imaging devices and techniques such as overlaying images captured by multiple imaging devices. Data collected by devices 1a to 1n / 2a to 2m, including image data, can be transferred to the cloud 204 or the local computer system 210 or both for data processing and manipulation including image processing and manipulation. The data can be analyzed to improve the results of the surgical procedure by determining whether additional treatment, such as application of endoscopic intervention, emerging technologies, targeted radiation, targeted intervention, precise robotics to specific tissue sites and conditions, can be followed. This data analysis can additionally use analytical processing of the results, and with the use of standardized approaches they can provide beneficial standardized feedback both to confirm surgical treatments and the surgeon's behavior or to suggest changes to surgical treatments and the behavior of the surgeon. surgeon.
[00171] [00171] In an implementation, operating room devices 1a to 1n can be connected to the central modular communication controller 203 via a wired channel or a wireless channel depending on the configuration of devices 1a to 1n on a controller central network. The central network controller 207 can be implemented, in one aspect, as a local network transmission device that acts on the physical layer of the OSI model ("open system interconnection"). The central network controller provides connectivity to devices 1a to 1n located on the same network as the operating room. The central network controller 207 collects data in the form of packets and sends them to the router in half - duplex mode. "The central network controller 207 does not store any media access control / Internet protocol (MAC / IP) to transfer data from the device, only one of the devices 1a to 1n at a time can send data through the central network controller 207. The central network controller 207 has no routing tables or intelligence about where to send information and transmits all network data through each connection and to a remote server 213 (Figure 9) via cloud 204. The central network controller 207 can detect basic network errors, such as collisions, but have all (admit) information transmitted to multiple ports of entry can be a security risk and cause strangulation.
[00172] [00172] In another implementation, operating room devices 2a to 2m can be connected to a network switch 209 through a wired or wireless channel. The network key 209 works in the data connection layer of the OSI model. Network switch 209 is a multicast device for connecting devices 2a to 2m located in the same operation center to the network. The network key 209 sends data in frames to the network router 211 and works in full duplex mode. Multiple devices 2a to 2m can send data at the same time via network key 209. Network key 209 stores and uses MAC addresses of devices 2a to 2m to transfer data.
[00173] [00173] The central network controller 207 and / or the network key 209 are coupled to the network router 211 for a connection with the number 204. The network router 211 works on the network layer of the OSI model. The network router 211 creates a route to transmit data packets received from the central network controller 207 and / or the network key 211 to a computer with cloud resources for future processing and manipulation of the data collected by any among or all of the devices 1a to 1n / 2a to 2m. The network router 211 can be used to connect two or more different networks located in different locations, such as different operating rooms in the same healthcare facility or different networks located in different operating rooms. operation of the different health service facilities. Network router 211 sends data in packet form to cloud 204 and works in full duplex mode. Multiple devices can send data at the same time. The network router 211 uses IP addresses to transfer data.
[00174] [00174] In one example, the central network controller 207 can be implemented as a central USB controller, which allows multiple USB devices to be connected to a host computer.

[00195] [00195] Figure 12 illustrates a logic diagram of a module of a 470 control system of a surgical instrument or tool, according to one or more aspects of the present description. The 470 system comprises a control circuit. The control circuit includes a microcontroller 461 comprising a 462 processor and a 468 memory. One or more of the sensors 472, 474, 476, for example, provides real-time feedback to the 462 processor. A motor 482, driven by a motor drive 492, operationally engages a longitudinally movable displacement member to drive the I-beam beam cutting element.

The safety controller can be configured specifically for IEC 61508 and ISO 26262 safety critical applications, among others, to provide advanced integrated safety features while providing scalable performance, connectivity and memory options.
[00198] [00198] The 461 microcontroller can be programmed to perform various functions, such as precise control of the speed and position of the articulation and cutting systems. In one aspect, the microcontroller 461 includes a processor 462 and a memory 468. The electric motor 482 can be a brushed direct current (DC) motor with a gearbox and mechanical connections with a hinge or cut system. In one aspect, a 492 motor drive can be an A3941 available from Allegro Microsystems, Inc. Other motor drives can be readily replaced for use in the 480 tracking system which comprises an absolute positioning system. A detailed description of an absolute positioning system is given in US Patent Application No. 2017/0296213, entitled SYSTEMS AND METHODS FOR CONTROLLING A SURGICAL STAPLING AND CUTTING INSTRUMENT, published on October 19, 2017, which is here incorporated as a reference in its entirety.
[00199] [00199] The 461 microcontroller can be programmed to provide precise control of the speed and position of the displacement members and articulation systems. The 461 microcontroller can be configured to compute a response in the 461 microcontroller software. The computed response is compared to a measured response from the real system to obtain an "observed" response, which is used for actual feedback-based decisions. The observed response is a favorable and adjusted value, which balances the uniform and continuous nature of the simulated response with the measured response, which can detect external influences in the system.
[00200] [00200] In one aspect, the 482 motor can be controlled by the 492 motor driver and can be used by the instrument trigger system or surgical tool. In many ways, the 482 motor can be a brushed direct current (DC) drive motor, with a maximum speed of approximately 25,000 RPM, for example. In other arrangements, the 482 motor may include a brushless motor, a wireless motor, a synchronous motor, a stepper motor or any other suitable type of electric motor. Motor starter 492 may comprise an H bridge starter comprising field effect transistors (FETs), for example. The 482 motor can be powered by a feed set releasably mounted on the handle set or tool compartment to provide control power for the instrument or surgical tool. The power pack may comprise a battery that may include several battery cells connected in series, which can be used as the power source to energize the instrument or surgical tool. In certain circumstances, the battery cells in the power pack may be replaceable and / or rechargeable. In at least one example, the battery cells can be lithium-ion batteries that can be coupled and separable from the power pack.
[00201] [00201] The 492 motor drive can be an A3941, available from Allegro Microsystems, Inc. The 492 A3941 drive is an entire bridge controller for use with semiconductor metal oxide field effect transistors (MOSFET ) of external power, N channel, specifically designed for inductive loads, such as brushed DC motors. The 492 actuator comprises a single charge pump regulator that provides full door drive (> 10 V) for batteries with voltage up to 7 V and allows the A3941 to operate with a reduced door drive, up to 5.5 V. An input command capacitor can be used to supply the voltage surpassing that supplied by the battery needed for the N channel MOSFETs. An internal charge pump for the drive on the upper side allows operation in direct current (100 % duty cycle). The entire bridge can be triggered in fast or slow drop modes using diodes or synchronized rectification. In the slow drop mode, the current can be recirculated by means of FET from the top or from the bottom. The energy FETs are protected from the shoot-through effect through programmable dead-time resistors. Integrated diagnostics provide indication of undervoltage, overtemperature and faults in the power bridge, and can be configured to protect power MOSFETs in most short-circuit conditions. Other motor drives can be readily replaced for use in the tracking system 480 comprising an absolute positioning system.
[00202] [00202] The tracking system 480 comprises a controlled motor drive circuit arrangement comprising a position sensor 472 in accordance with an aspect of the present description. The position sensor 472 for an absolute positioning system provides a unique position signal that corresponds to the location of a displacement member. In one aspect, the displacement member represents a longitudinally movable drive member comprising a rack of drive teeth for engagement with a corresponding drive gear of a gear reduction assembly. In other respects, the displacement member represents the firing member, which can be adapted and configured to include a drive tooth rack. In yet another aspect, the displacement member represents a firing bar or the I-shaped beam, each of which can be adapted and configured to include a rack of driving teeth. Consequently, as used in the present invention, the term displacement member is used generically to refer to any moving member of the surgical instrument, such as the driving member, the limb.
[00203] [00203] The electric motor 482 may include a rotary drive shaft, which interfaces operationally with a gear set, which is mounted on a coupling coupling with a set or rack of driving teeth on the driving member. A sensor element can be operationally coupled to a gear assembly so that a single revolution of the position sensor element 472 corresponds to some linear longitudinal translation of the displacement member. An array of gears and sensors can be connected to the linear actuator by means of a rack and pinion arrangement, or by a rotary actuator, by means of a gear wheel or other connection. A power supply supplies power to the absolute positioning system and an output indicator can display the output from the absolute positioning system. The drive member represents the longitudinally movable drive member which comprises a rack of drive teeth formed thereon for engagement with a corresponding drive gear of the gear reducer assembly. The displacement member represents the longitudinally movable firing member, the firing bar, the I-beam or combinations thereof.
[00204] [00204] A single revolution of the sensor element associated with the position sensor 472 is equivalent to a linear longitudinal displacement d1 of the displacement member, where d1 represents the longitudinal linear distance by which the displacement member moves from the point " a "to point" b "after a single revolution of the sensor element coupled to the displacement member. The sensor arrangement can be connected by means of a gear reduction which results in the position sensor 472 completing one or more revolutions for the complete travel of the displacement member. The position sensor 472 can complete multiple revolutions for the full travel of the displacement member.
[00205] [00205] A series of keys, where n is an integer greater than one, can be used alone or in combination with a gear reduction to provide a single position signal for more than one revolution of the position sensor 472. The state of the switches is transmitted back to microcontroller 461 which applies logic to determine a single position signal corresponding to the longitudinal linear displacement of d1 + d2 +… dn of the displacement member. The output of the position sensor 472 is supplied to the microcontroller 461. In several embodiments, the position sensor 472 of the sensor arrangement can comprise a magnetic sensor, an analog rotary sensor, such as a potentiometer, or a series of effect elements. Analog halls, which emit a unique combination of position of signals or values.
[00206] [00206] The position sensor 472 can comprise any number of magnetic detection elements, such as, for example, magnetic sensors classified according to whether they measure the total magnetic field or the vector components of the magnetic field. The techniques used to produce both types of magnetic sensors cover many aspects of physics and electronics. Technologies used for magnetic field detection include flow meter, saturated flow, optical pumping, nuclear precession, SQUID, Hall effect, anisotropic magneto-resistance, giant magnetoresistance, magnetic tunnel junctions, giant magnetoimpedance, magnetostrictive compounds / piesoelectrics, magnetodiode, magnetic transistor, optical fiber, magneto-optics and magnetic sensors based on microelectromechanical systems, among others.
[00207] [00207] In one aspect, the position sensor 472 for the tracking system 480 comprising an absolute positioning system comprises a magnetic rotating absolute positioning system. The 472 position sensor can be implemented as a rotary, magnetic, single-circuit position sensor,
[00208] [00208] The tracking system 480 comprising an absolute positioning system can comprise and / or be programmed to implement a feedback controller, such as a PID, state feedback, and adaptive controller. A power supply converts the signal from the feedback controller to a physical input to the system, in this case the voltage. Other examples include a voltage, current and force PWM. Other sensors can be provided in order to measure the parameters of the physical system in addition to the position measured by the position sensor 472. In some respects, the other sensors may include sensor arrangements as described in US Patent No. 9,345,481 entitled STAPLE CARTRIDGE TISSUE THI-
[00209] [00209] The absolute positioning system provides an absolute positioning of the displaced member on the activation of the instrument without having to retract or advance the longitudinally movable drive member to the restart position (zero or initial), as may be required by conventional rotary encoders that merely count the number of progressive or regressive steps that the 482 motor has traversed to infer the position of a device actuator, actuation bar, scalpel, and the like.
[00210] [00210] A 474 sensor, such as, for example, a strain gauge or a micro strain gauge, is configured to measure one or more parameters of the end actuator, such as, for example, the amplitude of the stress exerted on the anvil during a gripping operation, which can be indicative of tissue compression. The measured effort is converted into a digital signal and fed to the 462 processor. Alternatively, or in addition to the 474 sensor, a 476 sensor, such as a load sensor, can measure the closing force applied by the drive system. anvil closure. The 476 sensor, such as a load sensor, can measure the firing force applied to a beam with an I-profile in a firing stroke of the instrument or surgical tool. The i-profile beam is configured to engage a wedge slider, which is configured to move the clamp actuators upward to force the clamps to deform in contact with an anvil. The i-profile beam includes a sharp cutting edge that can be used to separate fabric, as the i-profile beam is advanced distally by the firing bar. Alternatively, a current sensor 478 can be used to measure the current drained by the 482 motor. The force required to advance the trigger member can correspond to the current drained by the 482 motor, for example. The measured force is converted into a digital signal and supplied to the 462 processor.
[00211] [00211] In one form, a 474 strain gauge sensor can be used to measure the force applied to the tissue by the end actuator. A strain gauge can be attached to the end actuator to measure the force applied to the tissue being treated by the end actuator. A system for measuring forces applied to the fabric attached by the end actuator comprises a 474 strain gauge sensor, such as a microstrain meter, which is configured to measure one or more parameters of the end actuator, for example example. In one aspect, the strain gauge sensor 474 can measure the amplitude or magnitude of the strain exerted on a claw member of an end actuator during a gripping operation, which can be indicative of tissue compression. The measured effort is converted into a digital signal and fed to the 462 processor of a 461 microcontroller. A 476 load sensor can measure the force used to operate the knife element, for example, to cut the captured tissue between the anvil and the staple cartridge. A magnetic field sensor can be used to measure the thickness of the captured tissue. The measurement of the magnetic field sensor can also be converted into a digital signal and supplied to the 462 processor.
[00212] [00212] Measurements of tissue compression, tissue thickness and / or force required to close the end actuator in the fabric, as measured by sensors 474, 476, can be used by microcontroller 461 to characterize the selected trigger member position and / or the corresponding trigger member speed value. In one case, a 468 memory can store a technique, an equation and / or a look-up table that can be used by the 461 microcontroller in the evaluation.

The 602 firing motor can be operationally coupled to a 604 firing motor drive assembly, which can be configured to transmitting firing movements generated by motor 602 to the end actuator, particularly to move the beam element with an I-profile. In certain cases, firing movements generated by motor 602 can cause the clamps to be positioned from the cartridge staples in the fabric captured by the end actuator and / or the cutting edge of the I-beam beam element to be advanced in order to cut the captured fabric, for example.

For example, memory 624 may include program instructions for controlling the firing motor 602, the closing motor 603 and the hinge motors 606a, 606b. Such program instructions can cause the 622 processor to control the trigger, close, and link functions according to inputs from the instrument or surgical tool control algorithms or programs.
[00231] [00231] In certain cases, one or more mechanisms and / or sensors, such as 630 sensors, can be used to alert the 622 processor about the program instructions that need to be used in a specific configuration. For example, sensors 630 can alert the 622 processor to use the program instructions associated with triggering, closing, and pivoting the end actuator. In certain cases, sensors 630 may comprise position sensors that can be used to detect the position of switch 614, for example. Consequently, processor 622 can use the program instructions associated with firing the beam with the I-profile of the end actuator by detecting, through sensors 630, for example, that switch 614 is in the first position 616; the processor 622 can use the program instructions associated with closing the anvil upon detection through sensors 630, for example, that switch 614 is in second position 617; and processor 622 can use the program instructions associated with the articulation of the end actuator upon detection through sensors 630, for example, that switch 614 is in the third or fourth position 618a, 618b.

For example, when thicker tissue is present, control circuit 710 can be programmed to translate the displacement member at a lower speed and / or with a lower power. When a thinner fabric is present, the control circuit 710 can be programmed to move the displacement member at a higher speed and / or with greater power.

In some instances, motors 704a to 704e may be brushed DC motors. For example, the speed of motors 704a to 704e can be proportional to the respective motor start signals. In some instances, motors 704a to 704e may be brushless DC electric motors, and the respective motor drive signals may comprise a PWM signal provided for one or more stator windings of motors 704a to 704e.

An external influence is an excessive and unpredictable influence on things like tissue, surrounding bodies, and friction in the physical system. This external influence can be called drag, which acts in opposition to the 754 electric motor. External influence, like drag, can cause the functioning of the physical system to deviate from a desired operation of the physical system.
[00261] [00261] Several exemplifying aspects are directed to a 750 surgical instrument that comprises a 752 end actuator with motor-driven surgical stapling and cutting implements. For example, a motor 754 can drive a displacement member distally and proximally along a longitudinal geometry axis of end actuator 752. End actuator 752 may comprise an articulating anvil 766 and, when configured for use, a cartridge of staples 768 positioned on the opposite side of anvil 766. A doctor can hold the tissue between the anvil 766 and the staple cartridge 768, as described here. When ready to use the 750 instrument, the physician can provide a trigger signal, for example, by pressing a trigger on the 750 instrument. In response to the trigger signal, the 754 motor can drive the displacement member distally along the axis longitudinal geometric pattern of end actuator 752 from a proximal start position to a distal end position from the start position. As the displacement member moves distally, the I-profile beam 764 with a cutting element positioned at a distal end can cut the fabric between the staple cartridge 768 and the anvil 766.
[00262] [00262] In several examples, the surgical instrument 750 may comprise a control circuit 760 programmed to control the distal translation of the displacement member, such as the beam with I-shaped profile 764, for example, based on one or more more tissue conditions. The control circuit 760 can be programmed to directly or indirectly detect tissue conditions, such as thickness, as described here. Control circuit 760 can be programmed to select a control program based on tissue conditions. A trigger control program can describe the distal movement of the displacement member. Different trigger control programs can be selected to better treat different tissue conditions. For example, when thicker tissue is present, control circuit 760 can be programmed to move the displacement member at a lower speed and / or with a lower power. When a thinner tissue is present, the control circuit 760 can be programmed to move the displacement member at a higher speed and / or with greater power.
[00263] [00263] In some examples, the control circuit 760 may initially operate the motor 754 in an open circuit configuration for a first open circuit portion of a travel of the travel member. Based on an instrument response 750 during the open circuit portion of the stroke, control circuit 760 can select a trip control program. The response of the instrument may include a travel distance of the displacement member during the open circuit portion, a time elapsed during the open circuit portion, the power supplied to the motor 754 during the open circuit portion, a sum of pulse widths a motor start signal, etc. After the open circuit portion, control circuit 760 can implement the selected trigger control program for a second portion of the travel member travel. For example, during the closed loop portion of the stroke, control circuit 760 can modulate motor 754 based on translation data that describes a position of the displacement member in a closed circuit manner to translate the displacement member into a constant speed. Additional details are described in US Patent Application Serial No. 15 / 720,852, entitled SYSTEM AND METHODS FOR CONTROL- LING A DISPLAY OF A SURGICAL INSTRUMENT, filed on September 29, 2017, which is hereby incorporated by reference in its entirety.
[00264] [00264] Figure 19 is a schematic diagram of a 790 surgical instrument configured to control various functions according to an aspect of the present description. In one aspect, surgical instrument 790 is programmed to control the distal translation of a displacement member, such as the I-profile beam 764. Surgical instrument 790 comprises an end actuator 792 that can comprise an anvil 766, a beam with I-profile 764 and a removable staple cartridge 768 that can be exchanged with an RF cartridge 796 (shown in dashed line).
[00265] [00265] In one aspect, the 788 sensors can be implemented as a limit switch, electromechanical device, solid state switches, Hall effect devices, MRI devices, GMR devices, magnetometers, among others. In other implementations, 638 sensors can be solid state switches that operate under the influence of light, such as optical sensors, infrared sensors, ultraviolet sensors, among others. In addition, the switches can be solid state devices such as transistors (for example, FET, junction FET, MOSFET, bipolar, and the like). In other implementations, the 788 sensors can include driverless electric switches, ultrasonic switches, accelerometers and inertia sensors, among others.
[00266] [00266] In one aspect, the position sensor 784 can be implemented as an absolute positioning system, which comprises a rotating magnetic absolute positioning system implemented as a rotating magnetic position sensor, with circuit single integrated, AS5055EQFT, available from Austria Microsystems, AG. The position sensor 784 can interface with the control circuit 760 to provide an absolute positioning system. The position may include multiple Hall effect elements located above a magnet and coupled to a CORDIC processor, also known as the digit by digit method and Volder algorithm,
[00267] [00267] In one aspect, the beam with I-shaped profile 764 can be implemented as the knife member comprising a knife body which operationally supports a fabric cutting blade in it and may additionally include flaps or anvil engagement and channel engagement features or a base. In one aspect, the staple cartridge 768 can be implemented as a standard surgical (mechanical) fastener cartridge. In one aspect, the RF cartridge 796 can be implemented as an RF cartridge. These and other sensor arrangements are described in U.S. Common Property Patent Serial No. 15 / 628,175, entitled TECHNIQUES
[00268] [00268] The position, movement, displacement and / or translation of a linear displacement member, such as the beam with I 764 profile, can be measured by an absolute positioning system, sensor arrangement and sensor of position represented as the 784 position sensor. As the beam with I-shaped profile 764 is coupled to a longitudinally movable drive member, the position of the beam with I-shaped profile 764 can be determined by measuring the position of the driving member longitudinally movable using the position sensor 784. Consequently, in the following description, the position, displacement and / or translation of the I-beam beam 764 can be obtained by the position sensor 784, as described in present invention. A control circuit 760 can be programmed to control the translation of the displacement member, such as the I-profile beam 764, as described here. The control circuit 760, in some examples, may comprise one or more microcontrollers, microprocessors or other suitable processors to execute the instructions that cause the processor or processors to control the displacement member, for example, the beam with profile in I 764, as described. In one aspect, a timer / counter 781 provides an output signal, such as elapsed time or a digital count, to the control circuit 760 to correlate the position of the beam with I-profile 764 as determined by the sensor position 784 with the timer / counter output 781 so that the control circuit 760 can determine the position of the beam with I-shaped profile 764 at a specific moment (t) in relation to an initial position. The 781 timer / counter can be configured to measure elapsed time, count external events, or measure timeless events.
[00269] [00269] The control circuit 760 can generate a setpoint signal for the engine 772. The setpoint signal for the engine 772 can be supplied to a 758 motor controller. The 758 motor controller can comprise one or more circuits configured to provide a motor 774 drive signal to motor 754 to drive motor 754, as described in the present invention. In some instances, the 754 motor may be a DC motor with a brushed DC electric motor. For example, motor speed 754 may be proportional to the motor 774 drive signal. In some instances, motor 754 may be a brushless DC electric motor and motor 774 drive signal may comprise a supplied PWM signal. - for one or more stator windings of motor 754. In addition, in some examples, motor controller 758 can be omitted, and control circuit 760 can generate motor drive signal 774 directly.
[00270] [00270] The 754 motor can receive power from a power source
[00271] [00271] The control circuit 760 can be in communication with one or more sensors 788. The sensors 788 can be positioned on the end actuator 792 and adapted to work with the surgical instrument 790 to measure the various derived parameters, such as distance span in relation to time, compression of the tissue in relation to time and tension of the anvil in relation to time. The 788 sensors can comprise a magnetic sensor, a magnetic field sensor, a stress meter, a pressure sensor, a force sensor, an inductive sensor such as a eddy current sensor, a resistive sensor, a capacitive sensor, a sensor optical and / or any other sensors suitable for measuring one or more parameters of the end actuator 792. The 788 sensors may include one or more sensors.
[00272] [00272] The one or more sensors 788 may comprise a stress meter, such as a microstrain meter, configured to measure the magnitude of the stress on the anvil 766 during a grip condition. The voltage meter provides an electrical signal whose amplitude varies with the magnitude of the voltage. The 788 sensors can comprise a pressure sensor configured to detect a pressure generated by the presence of compressed tissue between the anvil 766 and the staple cartridge 768. The 788 sensors can be configured to detect the impedance of a section of tissue located between the anvil 766 and the staple cartridge 768 which is indicative of the thickness and / or completeness of the fabric located between them.
[00273] [00273] The 788 sensors can be configured to measure the forces exerted on the anvil 766 by the closing drive system. For example, one or more sensors 788 may be at a point of interaction between a closing tube and anvil 766 to detect the closing forces applied by a closing tube to anvil 766. The forces exerted on anvil 766 can be represented - sensations of the tissue compression experienced by the tissue section captured between the anvil 766 and the staple cartridge 768. The one or more sensors 788 can be positioned at various points of interaction throughout the closing drive system to detect the closing forces applied to the anvil 766 by the closing drive system. The one or more 788 sensors can be sampled
[00274] [00274] A current sensor 786 can be used to measure the current drained by the 754 motor. The force required to advance the beam with I-shaped profile 764 corresponds to the current drained by the motor
[00275] [00275] An RF power source 794 is coupled to end actuator 792 and is applied to RF cartridge 796 when RF cartridge 796 is loaded on end actuator 792 in place of clamp cartridge 768. The circuit Control Panel 760 controls the supply of RF energy to the 796 RF cartridge.
[00276] [00276] Additional details are described in U.S. Patent Application Serial No. 15 / 636,096, entitled SURGICAL SYSTEM COU-
[00277] [00277] Figure 20 is a block diagram of a generator 800 configured to provide adjustment without inductor, among other benefits. Additional details of generator 800 are described in U.S. Patent No.
[00278] [00278] In certain forms, ultrasonic and electrosurgical trigger signals can be supplied simultaneously to different surgical instruments and / or to a single surgical instrument, such as a multifunctional surgical instrument, with the ability to supply both ultrasonic and electrosurgical energy to the tissue. It will be noted that the electrosurgical signal provided by both the dedicated electrosurgical instrument and the electrosurgical / ultrasound multifunction combined instrument can be both a therapeutic and subtherapeutic signal, where the subtherapeutic signal can be used, for example, to monitor tissue or the conditions of the instruments and provide feedback to the generator. For example, RF and ultrasonic signals can be provided separately or simultaneously from a generator with a single output port in order to provide the desired output signal to the surgical instrument, as will be discussed in more detail below. Consequently, the generator can combine the RF and ultrasonic electrosurgical energies and supply the combined energies to the multifunctional electro-surgical / ultrasonic instrument. Bipolar electrodes can be placed on one or both claws of the end actuator. A claw can be triggered by ultrasonic energy in addition to RF electrosurgical energy, working simultaneously. Ultrasonic energy can be used to perform tissue dissection while RF electrosurgical energy can be used to cauterize vessels.
[00279] [00279] The non-isolated stage 804 may comprise a power amplifier 812 that has an output connected to a primary winding 814 of the power transformer 806. In certain forms, the power amplifier 812 may comprise an amplifier of the type push and pull. For example, the non-isolated stage 804 may additionally comprise a logic device 816 to provide a digital output to a digital-to-analog converter (DAC) circuit 818 which, in turn, provides a analog signal corresponding to an input from the power amplifier 812. In certain forms, the logic device 816 may comprise a programmable gate array ("PGA"), a field programmable gate array ("FPGA" - field-programmable gate array), a programmable logic device ("PLD" - programmable logic device), among other logic circuits, for example. The logic device 816, by controlling the input of the power amplifier 812 through the DAC circuit 818, can therefore control any of several parameters (for example frequency, waveform, amplitude of the waveform) of drive signals appearing at the trigger signal outputs 810a, 810b and 810c. In certain ways and as discussed below, logic device 816, in conjunction with a processor (for example, a PSD discussed below), can implement various control algorithms based on digital signal processing (PSD) and / or others for control the parameters of the drive signal outputs supplied by the generator 800.
[00280] [00280] Power can be supplied to a power rail of the power amplifier 812 by a key mode regulator 820, such as, for example, a power converter. In certain ways, the 820 key mode regulator may comprise an adjustable antagonist regulator, for example. The non-isolated stage 804 may further comprise a first processor 822 which, in one form, may comprise a PSD processor such as an ADSP-21469 SHARC DSP, available from Analog Devices, Norwood, MA, USA, for example , although in various forms, any suitable processor can be used. In certain ways, the DSP processor 822 can control the operation of the key mode regulator 820 responsive to voltage feedback data received from the power amplifier 812 by the DSP processor 822 via an ADC 824 circuit. , for example, the DSP 822 processor can receive the waveform envelope of a signal (for example, an RF signal) as an input via the ADC 824 circuit, being amplified by the power amplifier
[00281] [00281] In certain forms, the logic device 816, in conjunction with the PSD 822 processor, can implement a digital synthesis circuit as a control scheme with a direct digital synthesizer to control the waveform, frequency and / or the amplitude of the trigger signals emitted by the generator 800. In one way, for example, the logic device 816 can implement a DDS control algorithm by retrieving waveform samples stored in a lookup table (LUT , "look-up table") dynamically updated, like a RAM LUT that can be integrated into an FPGA. This control algorithm is particularly useful for ultrasonic applications in which an ultrasonic transducer, such as an ultrasonic transducer, can be driven by a clean sinusoidal current at its resonant frequency. Since other frequencies can excite parasitic resonances, minimizing or reducing the total distortion of the branching current can correspondingly minimize or reduce the undesirable effects of resonance. As the waveform of a drive signal output by generator 800 is affected by several sources of distortion present in the output drive circuit (for example, the power transformer 806, the power amplifier 812), voltage and current feedback based on the trigger signal can be provided to an algorithm, such as an error control algorithm implemented by the PSD 822 processor, which compensates for the distortion through adequate pre-distortion or sample modification waveforms stored in the LUT in a dynamic and continuous manner (for example, in real time). In a way, the amount or degree of pre-distortion applied to the samples in the
[00282] [00282] The non-isolated stage 804 may additionally comprise a first ADC 826 circuit and a second ADC 828 circuit coupled to the output of the power transformer 806 by means of the respective isolation transformers, 830 and 832, for sampling respectively the voltage and current of the trigger signals emitted by the generator 800. In certain ways, the ADC 826 and 828 circuits can be configured for high speed sampling (for example, 80 mega samples per second ("MSPS" - mega samples per second)) to allow over-sampling of the trigger signals. In one form, for example, the sampling speed of the ADC 826 and 828 circuits can allow an oversampling of approximately 200 x (depending on the frequency) of the drive signals. In some ways, the sampling operations of the ADC 826 and 828 circuit can be performed by a single ADC circuit receiving voltage and current input signals through a bidirectional multiplexer. The use of high-speed sampling in the forms of the generator 800 can allow, among other things, the calculation of the complex current flowing through the branch of motion (which can be used in certain ways to implement waveform control based on in DDS described above), digital filtering needs the sampled signals and calculates the actual energy consumption with a high degree of accuracy. The voltage and current feedback data emitted by the ADC 826 and 828 circuits can be received and processed (for example, first-in-first-out buffers ("FIFO" - first-in-first-out ") , multiplexer) by logic device 816 and stored in data memory for subsequent retrieval, for example, by processor 822. As noted above, feedback data on voltage and current can be used as input to an algorithm for pre-distortion or modification of waveform samples in the LUT, in a dynamic and continuous way. In some ways, this may require that each pair of voltage and current feedback data stored be indexed based on in, or otherwise associated with, a sample of the corresponding LUT that was provided by logic device 816 when the voltage and current feedback data pair was captured. The synchronization of LUT samples with feedback information over and voltage and current in this way contributes to the correct timing and stability of the pre-distortion algorithm.
[00283] [00283] In certain forms, voltage and current feedback data can be used to control the frequency and / or amplitude (for example, current amplitude) of the trigger signals. In one way, for example, feedback data about voltage and current can be used to determine the impedance phase. The frequency of the trigger signal can then be controlled to minimize or reduce the difference between the determined impedance phase and an impedance phase set point (eg 0 °), minimizing or reducing thus the effects of harmonic distortion and,
[00284] [00284] In another form, for example, the current feedback data can be monitored in order to maintain the current amplitude of the drive signal at a current amplitude setpoint. The current amplitude set point can be specified directly or indirectly determined based on the specified set points for voltage amplitude and power. In certain ways, the control of the current amplitude can be implemented by the control algorithm, such as, for example, a proportional-integral-derivative control algorithm (PID), in the DSP 822 processor. The variables controlled by the control algorithm - le to properly control the current amplitude of the drive signal may include, for example, the scaling of the LUT waveform samples stored in logic device 816 and / or the full-scale output voltage of the circuit DAC 818 (which provides input to the power amplifier 812) via a DAC 834 circuit.
[00285] [00285] The non-isolated stage 804 can additionally comprise a second processor 836 to provide, among other things, the functionality of the user interface (UI). In one form, the UI 836 processor can comprise an Atmel AT91SAM9263 processor with an ARM 926EJ-S core, available from Atmel Corporation, of San Jose, CA, USA, for example. Examples of UI functionality supported by the UI 836 processor may include audible and visual feedback from the user, communication with peripheral devices (eg via a USB interface), communication with the foot switch, communication with a data entry device (for example, a touchscreen) and communication with an output device (for example, a speaker). The UI processor 836 can communicate with the DSP processor 822 and logic device 816 (for example, via SPI buses). Although the UI 836 processor can primarily support UI functionality, it can also coordinate with the PSD 822 processor to implement risk mitigation in certain ways. For example, the 836 processor can be programmed to monitor various aspects of the inputs by the user and / or other inputs (for example, touchscreen inputs, foot switch inputs, temperature sensor inputs) and can disable the drive output of generator 800 when an error condition is detected.
[00286] [00286] In certain ways, both the PSD 822 processor and the UI 836 processor can, for example, determine and monitor the operational state of generator 800. For the PSD 822 processor, the operational state of generator 800 can determine, for example, which control and / or diagnostic processes are implemented by the PSD 822 processor. For the UI 836 processor, the operational state of generator 800 can determine, for example, which elements of the UI (for example, display, sounds) are presented to a user. The respective UI and PSD processors 822 and 836 can independently maintain the current operational state of the generator 800, as well as recognize and evaluate possible transitions out of the current operational state. The PSD 822 processor can act as the master in this relationship and can determine when transitions between operational states should occur. The UI 836 processor can be aware of valid transitions between operational states and can confirm that a specific transition is appropriate. For example, when the PSD 822 processor instructs the UI 836 processor to transition to a specific state, the UI 836 processor can verify that the requested transition is valid. If a requested transition between states is determined to be invalid by the UI 836 processor, the UI 836 processor can cause generator 800 to enter a fault mode.
[00287] [00287] The non-isolated platform 804 may also contain an 838 controller for monitoring input devices (for example, a capacitive touch sensor used to turn the generator 800 on and off, a capacitive touch screen). In certain forms, controller 838 may comprise at least one processor and / or other controller device in communication with the UI 836 processor. In one way, for example, controller 838 may comprise a processor (for example, an 8-bit Meg168 controller available from Atmel) configured to monitor user inputs via one or more capacitive touch sensors. In one way, the 838 controller can comprise a touchscreen controller (for example, a QT5480 touchscreen controller available from Atmel) to control and manage the capture of touch data from a capacitive touchscreen to the touch.
[00288] [00288] In certain ways, when generator 800 is in an "off" state, controller 838 can continue to receive operational power (for example, through a line from a generator 800 power supply, such as power supply 854 discussed below). In this way, controller 838 can continue to monitor an input device (for example, a capacitive touch sensor located on a front panel of generator 800) to turn generator 800 on and off. When generator 800 is in the off state , the con-
[00289] [00289] In certain ways, controller 838 can cause generator 800 to provide audible feedback or other sensory feedback to alert the user that an on or off sequence has been initiated. This type of alert can be provided at the beginning of a sequence on or off, and before the start of other processes associated with the sequence.
[00290] [00290] In certain forms, the isolated stage 802 may comprise an instrument interface circuit 840 to, for example, provide a communication interface between a control circuit of a surgical instrument (for example, a control circuit that comprised of handle keys) and non-isolated stage 804 components, such as logic device 816, DSP processor 822 and / or UI processor 836. Instrument interface circuit 840 can exchange information with non-stage components isolated 804 by means of a communication link that maintains an adequate degree of electrical isolation between the isolated and non-isolated stages 802 and 804 such as, for example, an infrared (IV) communication link. Power can be supplied to the instrument interface circuit 840 using, for example, a low-drop voltage regulator powered by an isolation transformer driven from the 804 non-isolated stage.
[00291] [00291] In one form, the instrument interface circuit 840 can comprise a logic circuit 842 (e.g., a logic circuit, a programmable logic circuit, PGA, FPGA, PLD) in communication with a signal conditioning circuit 844 The signal conditioning circuit 844 can be configured to receive a periodic signal from logic circuit 842 (for example, a 2 kHz square wave) to generate a bipolar interrogation signal that has an identical frequency. The question mark can be generated, for example, using a bipolar current source powered by a differential amplifier. The question mark can be communicated to a surgical instrument control circuit (for example, using a conductor pair on a cable connecting the generator 800 to the surgical instrument) and monitored to determine a status or configuration the control circuit. The control circuit can comprise numerous switches, resistors and / or diodes to modify one or more characteristics (for example, amplitude, rectification) of the question mark so that a state or configuration of the control circuit is discernible, unequivocally, based on this one or more characteristics. In one form, for example, the signal conditioning circuit 844 may comprise an ADC circuit for generating samples of a voltage signal appearing between inputs of the control circuit, resulting from the passage of the interrogation signal through it. The logical instrument 842
[00292] [00292] In one form, the instrument interface circuit 840 may comprise a first data circuit interface 846 to enable the exchange of information between logic circuit 842 (or another element of the instrument interface circuit 840) and a first data circuit disposed in a surgical instrument or otherwise associated with it. In certain forms, for example, a first data circuit may be arranged on a cable integrally attached to a handle of the surgical instrument or on an adapter to interface between a specific type or model of surgical instrument and the generator 800. The first data circuit can be implemented in any suitable way and can communicate with the generator according to any suitable protocol, including, for example, as described here with respect to the first data circuit. In certain forms, the first data circuit may comprise a non-volatile storage device, such as an EEPROM device. In some ways, the first data circuit interface 846 can be implemented separately from logic circuit 842 and comprises a suitable circuit set (for example, separate logic devices, a processor) to allow communication between the logic circuit 842 and the first data circuit. In other ways, the first data circuit interface 846 can be integral with logic circuit 842.
[00293] [00293] In certain forms, the first data circuit can store information related to the specific surgical instrument with which it is associated. This information may include, for example, a model number, a serial number, a number of operations in which the surgical instrument was used, and / or any other types of information. This information can be read by the interface circuit.
[00294] [00294] As previously discussed, a surgical instrument can be removed from a handle (for example, the multifunctional surgical instrument can be removed from the handle) to promote interchangeability and / or disposability of the instrument. In such cases, conventional generators may be limited in their ability to recognize specific instrument configurations being used, as well as to optimize the control and diagnostic processes as needed. The addition of readable data circuits to surgical instruments to address this issue is problematic from a compatibility point of view, however. For example, designing a surgical instrument so that it remains retrocompatible with generators lacking the indispensable data reading functionality may be impractical due, for example, to different signaling schemes, design complexity and cost. The forms of instruments discussed here address these concerns through the use of data circuits that can be implemented in existing surgical instruments, economically and with minimal design changes to preserve the compatibility of surgical instruments with current generator platforms.
[00295] [00295] Additionally, the shapes of the generator 800 may allow communication with instrument-based data circuits. For example, generator 800 can be configured to communicate with a second data circuit contained in an instrument (for example, a multifunctional surgical instrument). In some ways, the second data circuit can be implemented in a manner similar to that of the first data circuit described here. The instrument interface circuit 840 may comprise a second data circuit interface 848 to enable such communication. In one form, the second data circuit interface 848 can comprise a three-state digital interface, although other interfaces can also be used. In certain ways, the second data circuit can generally be any circuit for transmitting and / or receiving data. In one form, for example, the second data circuit can store information related to the specific surgical instrument with which it is associated. This information may include, for example, a model number, a serial number, a number of operations in which the surgical instrument was used, and / or any other types of information.
[00296] [00296] In some ways, the second data circuit can store information about the ultrasonic and / or electronic properties of an associated ultrasonic transducer, end actuator or ultrasonic drive system. For example, the first data circuit can indicate an initialization frequency slope, as described here. Additionally or alternatively, any type of information can be communicated to the second data circuit for storage in it via the second data circuit interface 848 (for example, using logic circuit 842). This information may include, for example, an updated number of operations in which the surgical instrument was used and / or the dates and / or times of its use. In certain ways, the second data circuit can transmit data captured by one or more sensors (for example, an instrument-based temperature sensor). In certain ways, the second data circuit can receive data from generator 800 and provide an indication to a user (for example, an indication by light emitting diode or other visible indication) based on the received data.
[00297] [00297] In certain ways, the second data circuit and the second data circuit interface 848 can be configured so that communication between logic circuit 842 and the second data circuit can be carried out without the need to provide additional conductors for this purpose (for example, dedicated cable conductors connecting a handle to the 800 generator). In one way, for example, information can be communicated from and to the second data circuit using a wire bus communication scheme, implemented in the existing wiring, as one of the conductors used to transmit signals. question marks from signal conditioning circuit 844 to a control circuit on a handle. In this way, changes or modifications to the design of the surgical device that may otherwise be necessary are minimized or reduced. In addition, due to the fact that different types of communications implemented on a common physical channel can be separated based on frequency, the presence of a second data circuit can be "invisible" to generators that do not have the essential functionality of reading of data, which, therefore, allows the backward compatibility of the surgical instrument.
[00298] [00298] In certain forms, the isolated stage 802 may comprise at least one blocking capacitor 850-1 connected to the output of the drive signal 810b to prevent the passage of direct current
[00299] [00299] In certain embodiments, the non-isolated stage 804 may comprise a power supply 854 to provide DC power with adequate voltage and current. The power supply may comprise, for example, a 400 W power supply to deliver a system voltage of 48 VDC. The power supply 854 can additionally comprise one or more DC / DC voltage converters 856 to receive the power supply output to generate DC outputs at the voltages and currents required by the various components of generator 800. As discussed above in relation to the 838 controller, one or more of the 856 DC / DC voltage converters can receive an input from the 838 controller when the activation of the "on / off" input device by a user is detected by the 838 controller, to enable the operation or activation of the 856 DC / DC voltage converters.
[00300] [00300] Figure 21 illustrates an example of generator 900, which is a form of generator 800 (Figure 20). The 900 generator is configured to supply multiple types of energy to a surgical instrument.
[00301] [00301] A first voltage detection circuit 912 is coupled through the terminals identified as ENERGY1 and the RETURN path to measure the output voltage between them. A second voltage detection circuit 924 is coupled through the terminals identified as ENERGY2 and the RETURN path to measure the output voltage between them. A current detection circuit 914 is arranged in series with the RETURN leg on the secondary side of the power transformer 908, as shown to measure the output current for any energy modality. If different return paths are provided for each energy modality, then a separate current detection circuit would be provided on each return leg. The outputs of the first and second voltage detection circuits 912, 924 are supplied to the respective isolation transformers 916, 922 and the output of the current detection circuit 914 is supplied to another isolation transformer 918. The outputs of the Isolation formers 916, 928, 922 on the primary side of the power transformer 908 (non-isolated side of the patient) are supplied to one or more ADC 926 circuits. The digitized output from the ADC 926 circuit is supplied to the 902 processor for processing and additional computing. The output voltages and the output current feedback information can be used to adjust the output voltage and the current supplied to the surgical instrument, and to compute the output impedance, among other parameters. Input / output communications between the 902 processor and the patient's isolated circuits are provided through a 920 interface circuit.
[00302] [00302] In one aspect, impedance can be determined by processor 902 by dividing the output of the first voltage detection circuit 912 coupled over the terminals identified as ENERGY1 / RETURN or the second voltage detection circuit 924 coupled over the terminals identified as ENERGY2 / RETURN by the output of the current detection circuit 914 arranged in series with the RETURN leg on the secondary side of the power transformer 908. The outputs of the first and second voltage detection circuits 912, 924 are provided to separate the transformers 916, 922 isolations and the output of the current detection circuit 914 is provided for another isolation transformer 916. Digitized current and voltage detection measurements from the ADC 926 circuit are provided to the processor 902 to compute the impedance. As an example, the first ENERGIA1 energy modality can be ultrasonic energy and the second ENERGIA2 energy modality can be RF energy. However, in addition to the ultrasonic and bipolar or monopolar RF energy modalities, other energy modalities include irreversible and / or reversible electroporation and / or microwave energy, among others. In addition, although the example shown in Figure 21 shows a single RETURN return path that can be provided for two or more energy modes, in other respects, multiple RETURN return paths can be provided for each ENERGY energy mode. Thus, as described here, the impedance of the ultrasonic transducer can be measured by dividing the output of the first voltage detection circuit 912 by the current detection circuit 914 and the fabric impedance can be measured by dividing the output of the second voltage detection circuit
[00303] [00303] As shown in Figure 21, the generator 900 comprising at least one output port can include a power transformer 908 with a single output and multiple taps to provide power in the form of one or more modes of energy, such as ultrasonic, bipolar or monopolar RF, irreversible and / or reversible electroporation, and / or microwave energy, among others, for example, to the end actuator depending on the type of tissue treatment being performed. For example, the 900 generator can supply energy with higher voltage and lower current to drive an ultrasonic transducer, with lower voltage and higher current to conduct RF electrodes to seal the tissue or with a coagulation waveform for point coagulation using monopolar or bipolar RF electrosurgical electrodes. The output waveform of the 900 generator can be oriented, switched or filtered to supply the frequency to the end actuator of the surgical instrument. The connection of an ultrasonic transducer to the output of generator 900 would preferably be located between the output identified as ENERGY1 and the RETURN, as shown in Figure

[00305] [00305] As used throughout this description, the term "wireless" and its derivatives can be used to describe circuits, devices, systems, methods, techniques, communication channels etc., which can communicate data through the use of electromagnetic radiation modulated through a non-solid medium. The term does not imply that the associated devices do not contain any wires, although in some respects they may not. The communication module can implement any of a number of wireless and wired communication standards or protocols, including, but not limited to, Wi-Fi (IEEE 802.11 family), WiMAX (IEEE 802.16 family), IEEE 802.20 , long-term evolution (LTE, "long-term evolution"), Ev-DO, HSPA +, HSDPA +, HSUPA +, EDGE, GSM, GPRS, CDMA, TDMA, DECT, Bluetooth, Ethernet derivatives thereof, as well as any other wireless and wired protocols that are designated as 3G, 4G, 5G, and beyond. The computing module can include a plurality of communication modules. For example, a first communication module can be dedicated to short-range wireless communications like Wi-Fi and Bluetooth, and a second communication module can be dedicated to longer-range wireless communications like GPS, EDGE, GPRS , CDMA, WiMAX, LTE, Ev-DO, and others.
[00306] [00306] As used in the present invention, a processor or processing unit is an electronic circuit that performs operations on some external data source, usually memory or some other data flow. The term is used in the present invention to refer to the central processor (central processing unit) in a computer system or systems (specifically systems on a chip (SoCs)) that combine several specialized "processors".
[00307] [00307] As used here, a system on a chip or system on the chip (SoC or SOC) is an integrated circuit (also known as an "IC" or "chip") that integrates all components of a computer or other electronic systems. It can contain digital, analog, mixed and often radio frequency functions - all on a single substrate. A SoC integrates a microcontroller (or microprocessor) with advanced peripherals such as a graphics processing unit (GPU), i-Fi module, or coprocessor. An SoC may or may not contain internal memory.
[00308] [00308] As used here, a microcontroller or controller is a system that integrates a microprocessor with peripheral circuits and memory. A microcontroller (or MCU for the microcontroller unit) can be implemented as a small computer on a single integrated circuit. It can be similar to a SoC; a SoC can include a microcontroller as one of its components. A microcontroller can contain one or more core processing units (CPUs) together with memory and programmable input / output peripherals. Program memory in the form of ferroelectric RAM, NOR flash or OTP ROM is also often included on the chip, as well as a small amount of RAM. Microcontrollers can be used for integrated applications, in contrast to microprocessors used in personal computers or other general purpose applications that consist of several separate integrated circuits.
[00309] [00309] As used in the present invention, the term controller or microcontroller can be an independent chip or IC (integrated circuit) device that interfaces with a peripheral device. This can be a connection between two parts of a computer or a controller on an external device that manages the operation of (and connection to) that device.
[00310] [00310] Any of the processors or microcontrollers in the present invention can be any implemented by any single-core or multi-core processor, such as those known under the trade name of ARM Cortex available from Texas Instruments. In one respect, the processor may be a Core Cortex-M4F LM4F230H5QR ARM processor, available from Texas Instruments, for example, which comprises an integrated 256 KB single-cycle flash memory, or other non-volatile memory, up to 40 MHz , a search-ahead buffer to optimize performance above 40 MHz, a 32 KB single cycle serial random access memory (SRAM), an internal read-only memory (ROM) loaded with the StellarisWare® program , 2 KB electronically erasable programmable read-only memory (EEPROM), one or more pulse width modulation (PWM) modules, one or more quadrature encoder (QEI) input analogues, one or more converters 12-bit analog to digital (ADC) with 12 channels of analog input, details of which are available for the product data sheet.
[00311] [00311] In one aspect, the processor may comprise a safety controller that comprises two controller-based families, such as TMS570 and RM4x, known under the trade name of Hercules ARM Cortex R4, also available from Texas Instruments . The safety controller can be configured specifically for the critical safety applications IEC 61508 and ISO 26262, among others, to provide advanced features of integrated safety while providing scalable performance, connectivity and memory options.
[00312] [00312] The modular devices include the modules (as described in connection with Figures 3 and 9, for example) that are received within a central surgical controller and the devices or surgical instruments that can be connected to the various modules a in order to connect or pair with the corresponding central surgical controller. Modular devices include, for example,
[00313] [00313] Surgical procedures are performed by different surgeons in different locations, some with much less experience than others. For a given surgical procedure, there are many parameters that can be varied to try to achieve a desired result. For example, for a given surgical procedure that uses energy supplied by a generator, the surgeon often relies on experience only to determine which mode of energy to use, what level of output power to use, during
[00314] [00314] Each of a plurality of operating rooms located in multiple locations can be equipped with a central surgical controller. When a particular surgical procedure is performed in a given operating room, the central surgical controller can receive data associated with the surgical procedure and communicate the data to a cloud-based system. Over time, the cloud-based system will receive large data sets of information associated with the surgeries. Data can be communicated from central surgical controllers to the cloud-based system in a way that allows the cloud-based system (1) to verify the authenticity of the reported data, (2) authenticate each of the respective controllers central surgeons who communicated the data and (3) tracks the data trajectories followed by the respective central surgical controllers to the cloud-based system.
[00315] [00315] Consequently, in one aspect, the present description provides a central surgical controller to transmit the generator data associated with a surgical procedure to a cloud-based system communicatively coupled to a plurality of central surgical controllers. The central surgical controller comprises a processor and a memory attached to the processor. The memory stores instructions executable by the processor to receive data from a generator, encrypt the data, generate a message authentication code (MAC) based on the data, generate a data tag that comprises the encrypted data, the generated MAC, a source identifier and a destination identifier, and transmit the da- tagrama to a cloud-based system. The data is structured in a data package that comprises at least two of the following fields: a field that indicates the source of the data, an exclusive timestamp, a field indicating a generator power mode, a field indicating the generator's power output and a field indicating a duration of the generator's power output. The da- tagrama allows the cloud-based system to decrypt the encrypted data from the transmitted datagram, verify the data integrity based on the MAC, authenticate the central surgical controller as the source of the datagram and validate a transmission path followed by the datagram between the central surgical controller and the cloud-based system.
[00316] [00316] In several respects, this description provides a control circuit to transmit the generator data associated with a surgical procedure to a cloud-based system communicatively coupled to a plurality of cyclic controllers
[00317] [00317] In another aspect, the present description provides a cloud-based system communicatively coupled to a plurality of central surgical controllers. Each central surgical controller is configured to transmit data from the generator associated with a surgical procedure to the cloud-based system. The cloud-based system comprises a processor and a memory attached to the processor. The memory stores instructions executable by the processor to receive a datagram generated by a central surgical controller of the surgical instrument, decrypt the encrypted generator data, verify the integrity of the generator data based on MAC data, authenticate the central surgical controller as the datagram source and validate a transmission path followed by the datagram the central surgical controllers and the cloud-based system. The generator comprises generator data captured from a generator associated with the central surgical controller, a MAC generator by the central surgical controller based on the generator data, a source identifier and a destination identifier. The data generator was encrypted by the central surgical controller. The encrypted generator data was structured in a data package that comprises at least two of the following fields: a field indicating the source of the data, an exclusive timestamp, a field indicating a power mode, a field indicating a power output and a field indicating an applied power duration.
[00318] [00318] In several aspects, the present description provides a control circuit to transmit data from the generator associated with a surgical procedure to the cloud-based system. In many respects, the present description provides a non-transitory, computer-readable medium that stores computer-readable instructions that, when executed, cause a machine to transmit generator data associated with a surgical procedure to the cloud-based system.
[00319] [00319] In another aspect, the present description provides a method which comprises capturing data from a combined generator of a central surgical controller during a surgical procedure, the combined generator being configured to supply two or more different modes of energy . Encrypt the captured generator data, generate a MAC based on the captured generator data, generate a datagram comprising the encrypted generator data, the MAC, a source identifier and a destination identifier, and communicate the datagram to from the central surgical controller to a cloud-based system. The datagram allows the cloud-based system to authenticate the integrity of the reported generator data, authenticate the central surgical controller as a source of the datagram and determine a communication path followed by the datagram between the central surgical controller and the surgical system based on a cloud.
[00320] [00320] By sending generator data captured from a plurality of different central surgical controllers to a cloud-based system, the cloud-based system is able to quickly build large data sets of information associated with multiple procedures surgical procedures performed in multiple locations over time. In addition, due to the composition of the
[00321] [00321] Unfortunately, the result of a surgical procedure is not always ideal. For example, a failure event, such as surgical device failure, unwanted tissue perforation, postoperative hemorrhage, or the like, can occur. The occurrence of a failure event can be attributed to any one of a variety of different people and devices, including one or more surgeons, one or more devices associated with the surgery, a patient's condition and combinations thereof. When a given failure occurs, it is not always clear who or what caused the failure event or how the occurrence of the failure event can be mitigated in connection with future surgery.
[00322] [00322] During a given surgical procedure, a large amount of data associated with the surgical procedure can be generated and captured. All captured data can be communicated to a central surgical controller, and captured data can be stamped with a date and time before or after being received at the central surgical controller. When a failure event associated with the surgical procedure is detected and / or identified, it is possible to determine which captured data are associated with the failure event and / or which captured data are not associated with the failure event. To make this determination, the failure event can be defined to include a period of time before the detection / identification of the failure event. Once the determination is made in relation to the captured data associated with the failure event, the central surgical controller can separate the captured data associated with the failure event from all other captured data, and the captured data can be separated based in marking, signage or similar. The captured data associated with the failure event can,
[00323] [00323] When a given surgical procedure is performed, a large amount of data associated with the surgical procedure can be generated and captured. All captured data can be communicated to a central surgical controller, where the information can be removed from all "personal" associations. Captured data can be timestamped before being received at the central surgical controller, after being received at the central surgical controller, before being stripped of "personal" associations or after being stripped of "personal" associations. The central surgical controller can communicate the deprived data to the cloud-based system for subsequent analysis. Over time, the cloud-based system will receive large data sets of information associated with the surgeries.
[00324] [00324] Consequently, in one aspect, the present description provides a central surgical controller to prioritize surgical data associated with a surgical procedure for a cloud-based system communicatively coupled to a plurality of central surgical controllers. The central surgical controller comprises a processor and a memory attached to the processor. The memory stores instructions executable by the processor to capture surgical data, the surgical data comprising data associated with a surgical device, stamping the captured surgical data with date and time, identifying a failure event, identifying a period time associated with the failure event, isolate the surgical data from the failure event from the surgical data not associated with the failure event based on the identified time period, place the surgical data from the failure event in chronological order by timestamp, encrypt the surgical data of the failure event in chronological order, generate a datagram comprising the surgical data of the failure event and transmit the datagram to a cloud-based system. The datagram is structured to include a field that includes an indicator that prioritizes the surgical data from the encrypted failure event over other encrypted data in the da- tagrama. The datagram enables the cloud-based system to decrypt the encrypted failure event surgical data, concentrate the analysis on the surgical data of the failure event and not on the surgical data not associated with the failure event, and indicate the surgical device associated with the failure event. failure during at least one of them: removal of an operating room, return to a manufacturer or future inoperability in the cloud-based system.
[00325] [00325] In several aspects, this description provides a control circuit to prioritize surgical data associated with a surgical procedure for a cloud-based system communicatively coupled to a plurality of central surgical controllers. In many respects, this description provides a non-transitory, computer-readable media that stores computer-readable instructions that, when executed, cause a machine to prioritize surgical data associated with a surgical procedure for a coupled cloud-based system communicatively to a plurality of central surgical controllers.
[00326] [00326] In another aspect, the present description provides a method that comprises capturing data during a surgical procedure, communicating the captured data to a central surgical controller, stamping the date and time on the captured data, identifying a failure event associated with the surgical procedure, determine which captured data are associated with the failure event, separate the captured data associated with the failure event from all other captured data, place the captured data in chronological order associated with the failure event and communicate the captured data in chronological order to a cloud-based system in a priority manner.
[00327] [00327] By capturing the large amount of data associated with the surgical procedure and with the data stamped with date and time, the portion of captured data that is relevant to the detected / identified failure event can be more easily isolated from all the other captured data, thus enabling a subsequent more focused analysis on only the relevant captured data. The data associated with the failure event can then be placed in chronological order (this requires less processing power than placing all captured data in chronological order), thus enabling the events that lead the detection / identification of the failure event are more easily considered during the subsequent analysis of the failure event. The data in chronological order can then be communicated to the cloud-based system (this requires less communication resources than communicating all the captured data at the same time) in a prioritized way, thus allowing the subsequent analysis to be carried out focused on the failure event by the cloud-based system in a more time-sensitive way.
[00328] [00328] To help ensure that best practice recommendations are developed based on accurate data, it would be desirable to ensure that the generator data received on the cloud-based system is the same as the generator data communicated to the cloud-based system. In addition, to help determine the cause of a failure event as quickly as possible, it would be desirable to ensure that the surgical data associated with the failure event is communicated to the cloud-based system in a prioritized manner (in relation to non-surgical data) associated with the failure event) so that the analysis of surgical data can be carried out in an accelerated way.
[00329] [00329] Aspects of a system and method for communicating data associated with a surgical procedure are described in the present invention. As shown in Figure 9, various aspects of the computer-implemented interactive surgical system 200 include a device / instrument 235, a generator module 240, a modular control tower 236 and a cloud-based system 205. As shown in Figure 10 , device / instrument 235, generator module 240 and modular control tower 236 are components / portions of a central surgical controller 206.
[00330] [00330] In several respects, generator module 240 of central surgical controller 206 can deliver radio frequency energy, such as monopolar radio frequency energy, bipolar radio frequency energy, advanced bipolar energy and / or ultrasonic energy, to a device / instrument 235 for use in a surgical procedure. Thus, generator module 240 can be called a combined generator. An example of this type of combined generator is shown in Figure 22, where the combined generator 3700 generator is shown as including a monopolar module 3702, a bipolar module 3704, an advanced bipolar module 3706 and an ultrasound module 3708. When used during a surgical procedure, the respective energy modules (for example, 3702, 3704, 3706 and / or
[00331] [00331] Figure 23 illustrates various aspects of a method of capturing data from a combined 3700 generator and communicating captured data to a cloud-based system 205. Notably, as discussed in this document, this des - description should not be limited to the data processing of the generator. Thus, the method of Figure 23 extends, similarly, to other types of data received from other components coupled to the central surgical controller 206 (for example, data from imaging module data, smoke evacuator data, suction data - tion / irrigation, device / instrument data). The method comprises (1) capturing 3712 data from a combined generator 3700 from a central surgical controller 206 during a surgical procedure, with the combined generator 3700 being configured to provide two or more different energy modes; (2) encrypt 3714 captured generator data; (3) generate 3716 a MAC based on the captured generator data; (4) generate a 3718 datagram comprising the encrypted generator data, the MAC, a source identifier and a destination identifier; (5) and communicate the datagram 3720 from the central surgical controller 206 to a cloud-based system 205, the datagram enabling the cloud-based system 205 (i) to authenticate the integrity of the reported generator data , (ii) authenticate the central surgical controller as a source of the datagram and (iii) determine a communication path
[00332] [00332] More specifically, since the data generator is received in the data communication module 3710 of the combined generator 3700, the data from the generator can be communicated to the modular communication center 203 of the central surgical controller 206 to subsequent communication to the cloud-based system 205. The data communication module 3710 can communicate data from the generator to the modular communication center 203 in series over a single communication line or in parallel over a plurality of lines of communication, and such communication can be done in real time or in near real time. Alternatively, such communication can be carried out in batches.
[00333] [00333] According to several aspects, before communicating the generator data to the modular communication center 203, a component of the combined generator 3700 (for example, the data communication module 3710) can organize the generator data into packages of data. An example of such a data packet is shown in Figure 24, in which data packet 3722 includes a preamble 3724 or self-describing data header that defines what the data is (for example, combined generator data ("CGD" , given generator combination)) and fields that indicate where the generator data came from (eg combined generator ID number 3726 - (eg 017), a unique time stamp 3728 (for example, 08:27:16), the energy mode used 3730 (for example, RF, U, RF + U), the type of radio frequency energy or 3732 radio mode (for example, MP, BP, ABP), frequency 3734 (eg 500 kHz), power output 3736 (eg 30 Watts), duration of applied power 3738 (eg 45 milliseconds) and a point authentication / identification certificate 3740 (for example, 01101011001011)). The 3722 exemplary data pack can be considered a self-describing data pack and the combined generator 3700 and other smart devices (for example, the central surgical controller 206) can use the self-describing data pack to minimize the size of the data and data manipulation capabilities. Again, as discussed in this document, the present description should not be limited to the processing of generator data received from a combined generator 3700. Thus, the data package 3722 of Figure 24, similarly, if extends to other types of data received from other components coupled to the central surgical controller 206. In one aspect, the 3722 data package can comprise data associated with the 239 endoscope (for example, image data) received from a imaging module component 238. In another aspect, the 3722 data package can comprise data associated with an evacuation system (for example, pressures, particle counts, flow rates, engine speeds) received from a component of the smoke evacuation module
[00334] [00334] Additionally, the 3710 data communication module can compress the generator data and / or encrypt the generator data before communicating the generator data to the modular communication center 203. The specific method of compression and / or crypto-
[00335] [00335] The modular communication center 203 can receive the generator data communicated from the combined generator 3700 (for example, via the data communication module 3710), and the generator data can subsequently be communicated to the 205 cloud-based system (for example, over the internet). According to several aspects, the modular communication core 203 can receive the generator data via a central controller / key 207/209 of the modular communication core 203 (see Figure 10), and the generator data can be communicated to the cloud-based system 205 by a router 211 of the modular communication core 203 (see Figure 10). Generator data can be communicated in real time, close to real time or in batches to the cloud-based system 205 or can be stored in the central surgical controller 206 before being communicated to the 205-based system. Generator data they can be stored, for example, in storage matrix 234 or in memory 249 of computer system 210 of central surgical controller 206.
[00336] [00336] In several respects, for cases in which the data received from the generator at the modular communication center 203 is not encrypted, before the data received from the generator is transmitted to the cloud-based system 205, the generator data is encrypted to help ensure the confidentiality of generator data, while it is being stored in the central surgical controller 206 or while it is being transmitted to the cloud 204 using the internet or other computer networks. According to several aspects, a component of the central surgical controller 206 uses an encryption algorithm to convert data
[00337] [00337] Using a symmetric encryption algorithm, the central surgical controller 206 would encrypt the generator data using a shared secret (for example, private key, passphrase, password). In this respect, a recipient of the encrypted generator data (for example, cloud-based system 205) would then decrypt the generator data encrypted using the same shared secret. In such an aspect, the central surgical controller 206 and the recipient would need to access and / or know the same shared secret. In one aspect, a shared secret can be generated / chosen by the central surgical controller 206 and delivered securely (for example, physically) to the recipient before encrypted communications to the recipient.
[00338] [00338] Alternatively, using an asymmetric encryption algorithm, the central surgical controller 206 would encrypt the generator data using a public key associated with a recipient (for example, cloud-based system 205). This public key could be received by the central surgical controller 206 from a certificate authority that issues a digital certificate certifying that the public key is owned by the recipient. The certificate authority can be any entity trusted by the central surgical controller 206 and the recipient. In such an aspect, the recipient of the encrypted generator data would then decrypt the generator data encrypted using a private key (that is, known only to the recipient) paired with the public key used by the central surgical controller 206 to encrypt the generator data. Notably, in such an aspect, the encrypted generator data can be decrypted only with the use of the recipient's private key.
[00339] [00339] In accordance with aspects of the present description, the components (eg surgical device / instrument 235, energy device 241, endoscope 239) of surgical system 202 are associated with unique identifiers, which can be in the form of serial numbers. Thus, according to several aspects of the present description, when a component is coupled to a central surgical controller 206, the component can establish a shared secret with the central surgical controller 206 using the unique identifier of the coupled component as the shared secret. Additionally, in such an aspect, the component can derive a checksum value by applying a checksum function / algorithm for the unique identifier and / or other data that is communicated to the central surgical controller 206. Here, the checksum function / algorithm is configured to produce a significantly different checksum value if there is a change in the underlying data.
[00340] [00340] In one aspect, the component can initially encrypt the unique identifier of a coupled component using a public key associated with the central surgical controller (for example, received by the central surgical controller component 206 before / after connection) and communicate the encrypted unique identifier to the central surgical controller 206. In other respects, the component can encrypt the unique identifier and the checksum value derived from a coupled component using a public key associated with the central surgical controller 206 and communicate the encrypted unique identifier and the checksum value connected / associated to the central surgical controller 206.
[00341] [00341] In still other aspects, the component can encrypt the unique identifier and a checksum function / algorithm using a public key associated with the central surgical controller 206 and communicate the encrypted unique identifier and the function / summation verification algorithm for the central surgical controller 206. In these aspects, the central surgical controller 206 would then decrypt the encrypted unique identifier or the encrypted unique identifier and the linked checksum value / associated or the encrypted unique identifier and the checksum function / algorithm using a private key (ie known only to the central surgical controller 206) paired to the public key used by the component to encrypt the unique identifier.
[00342] [00342] Since the encrypted unique identifier can be deciphered only using the private key of the central surgical controller 206 and the private key is known only to the central surgical controller, this is a safe way to communicate a shared secret (for example , the unique identifier of the coupled component) for the central surgical controller 206. Additionally, in aspects where a checksum value is linked / associated with the unique identifier, the central surgical controller 206 can apply the same function / algorithm checksum to the decrypted unique identifier to generate a validation checksum value. If the validation checksum value matches the decrypted checksum value, the integrity of the decrypted unique identifier is further verified.
[00343] [00343] Notably, asymmetric cryptography algorithms can be complex and may require significant computational resources to execute each communication. Thus, establishing the unique identifier of the coupled component as a shared secret, in addition to being faster (for example, there is no need to generate a shared secret using a pseudo-random key generator), it also increases computational efficiency. (for example, it allows the execution of faster, less complex symmetric encryption algorithms) for all subsequent communications. In several ways, this shared shared secret can be used by the component and the central surgical controller 206 until the component is decoupled from the central surgical controller (for example, the procedure).
[00344] [00344] In accordance with other aspects of the present description, the components (e.g. surgical device / instrument 235, energy device 241, endoscope 239) of the surgical system 202 may comprise subcomponents (e.g., handle, drive shaft, actuator endpoint, cartridge), each associated with its own unique identifier. Thus, according to several aspects of the present description, when a component is coupled to the central surgical controller 206, the component can establish a shared secret with the central surgical controller 206 with the use of an exclusive build / sequence sive (for example, ordered or random) of the unique identifiers associated with the subcomponents that combine to form the coupled component. In one aspect, the component can initially encrypt the compilation / unique sequence of the coupled component using a public key associated with the central part 206 and communicate the encrypted exclusive compilation / sequence to the central surgical controller 206. In such an aspect, the surgical controller - central logic 206 would then decrypt the exclusive build / sequence using a private key (ie known only to the central surgical controller 206) paired with the public key used by the component to encrypt the unique build / sequence. Since the compilation / sequence of the encrypted unique identifier can be decrypted only using the private key of the central surgical controller 206 and the private key is known only to the central surgical controller 206, this is a safe way to communicate a secret shared (for example, the exclusive compilation / sequence of the coupled component) for the central surgical controller 206. In addition, in this respect, with an established shared secret, the component can encrypt future communications.
[00345] [00345] Again, asymmetric cryptographic algorithms can be complex and may require significant computational resources to perform each communication. Thus, establishing the exclusive compilation / sequence of the coupled component (that is, readily combinable by the component), since the shared secret is not only faster (for example, there is no need to generate a shared secret with the use of a pseudo-random key generator), it also increases computational efficiency (for example, it allows the execution of faster, less complex symmetric encryption algorithms) for all subsequent communications. In many respects, this shared shared secret can be used by the component and the central surgical controller 206 until the component is decoupled from the central surgical controller 206 (for example, the surgical procedure has ended). Furthermore, in such an aspect, since several subcomponents may be reusable (for example, handle, drive shaft, end actuator), while other subcomponents may not be reusable (for example, end actuator - of, cartridge), each new combination of subcomponents that combine to form the coupled component provides a unique build / sequence usable as a shared secret for component communications to the central surgical controller
[00346] [00346] In accordance with additional aspects of the present description, the components (e.g., surgical device / instrument 235, energy device 241, endoscope 239) of surgical system 202 are associated with unique identifiers. Thus, according to several aspects of the present description, when a component is coupled to the central surgical controller 206, the central surgical controller 206 can establish a secret shared with a recipient (for example, cloud-based system 205) with the use of the unique identifier of the coupled component. In one aspect, the central surgical controller 206 can initially encrypt the unique identifier of a coupled component using a public key associated with the recipient and communicate the encrypted unique identifier to the recipient. In such an aspect, the recipient would then decrypt the unique identifier using a private key (i.e., known only to the recipient) paired with the public key used by the central surgical controller 206 to encrypt the unique identifier. Since the encrypted unique identifier can only be decrypted using the recipient's private key and the private key is known only to the recipient, this is a secure way to communicate a shared secret (for example, the unique identifier of the attached component) to the recipient (for example, example, cloud-based system). In addition, with a shared shared secret, the central surgical controller 206 can encrypt future communications to the recipient (for example, cloud-based system 205), and the recipient can decrypt future communications from the surgical controller. - central co 206 using the shared secret (for example, the unique identifier of the coupled component).
[00347] [00347] Notably, asymmetric cryptographic algorithms can be complex and may require significant computational resources to execute each communication. Thus, establishing the unique identifier of the coupled component (that is, readily available to the central surgical controller 206), since the shared secret is not only faster (for example, there is no need to generate a shared secret with the use of a pseudo-random key generator), also increases computational efficiency, for example, allowing the execution of faster, less complex symmetric encryption algorithms for all subsequent communications. In many respects, this shared shared secret can be used by the central surgical controller 206 until the component is decoupled from the central surgical controller (for example, the surgical procedure has ended).
[00348] [00348] In accordance with still other aspects of the present description, the components (for example, surgical device / instrument 235, energy device 241, endoscope 239) of the surgical system 202 may comprise subcomponents (for example, handle, drive shaft, end actuator, cartridge), each associated with its own unique identifier. Thus, according to several aspects of the present description, when a component is coupled to the central surgical controller 206, the central surgical controller 206 can establish a shared secret with a recipient (for example, cloud-based system 205) with the use of a unique compilation / sequence (for example, ordered or random) of the unique identifiers associated with the subcomponents that combine to form the coupled component.
[00349] [00349] In one aspect, the central surgical controller 206 can initially encrypt the compilation / sequence of the coupled component using a public key associated with the recipient and communicate the exclusive compilation / sequence to the recipient. In such an aspect, the recipient would then decrypt the compilation / exclusive sequence encrypted using a private key (ie known only to the recipient) paired with the public key used by the central surgical controller 206 to encrypt compilations.
[00350] [00350] In several respects, this shared shared secret can be used by the central surgical controller 206 until the component is decoupled from the central surgical controller (for example, the surgical procedure has ended). Furthermore, in such an aspect, since several subcomponents may be reusable (for example, handle, drive shaft, end actuator), while other subcomponents may not be reusable (for example, end actuator, cartridge ), each new combination of subcomponents
[00351] [00351] In some respects, an encryption-after-MAC (EtM) approach can be used to produce the encrypted generator data. An example of this approach is shown in Figure 25, in which the generator's unencrypted data (ie, plain text 3742, for example, data packet 3722) is first encrypted 3743 (for example, via key 3746) for produce a ciphertext 3744 (ie, the encrypted generator data), then a MAC 3745 is produced based on the resulting ciphertext 3744, key 3746 and the MAC algorithm (ie, a hash function 3747). More specifically, the ciphertext 3744 is processed using the MAC algorithm using the 3746 key. In a similar aspect to the symmetric encryption discussed in the present invention, the 3746 key is a secret key accessible / known to the central surgical controller 206 and by the recipient (for example, cloud-based system 205). In such an aspect, the secret key is a shared secret associated with / chosen by the central surgical controller 206, a shared secret associated with / chosen by the recipient, or a key selected by means of a pseudo-random key generator. For this approach, as generally shown in 3748, the encrypted generator data (that is, the ciphertext 3744) and MAC 3745 would be communicated together to the 205 cloud-based system.
[00352] [00352] In other respects, an encryption-e-MAC (E&M) approach can be used to produce the encrypted generator data. An example of this approach is shown in Figure 26, in which MAC 3755 is produced based on the generator's unencrypted data (ie, a plain text 3752, for example, data packet
[00353] [00353] In still other aspects, a MAC-after-encryption (MtE) approach can be used to produce the encrypted generator data. An example of this approach is shown in Figure 27, in which MAC 3765 is produced based on unencrypted generator data (that is, a plain text 3762), a 3766 key and a MAC algorithm (for example, a hash function 3767 ). More specifically, plain text 3762 is processed using the MAC algorithm using the 3766 key. In a similar aspect to the symmetric encryption discussed in the present invention, key 3766 is a secret key accessible / known to the central surgical controller 206 and by recipient (eg 205 cloud-based system). In this respect, the secret key is a shared secret associated with / chosen by the central surgical controller 206, a shared secret associated with / chosen by the recipient, or a key selected using a pseudo-random key generator. Then, the generator's unencrypted data (that is, plain text 3762) and MAC 3765 are encrypted together 3763 (for example, using key 3766) to produce a 3764 cipher text based on both. For this approach, as shown in general in 3768, the ciphertext 3764 (ie, which includes the generator encrypted data and the 3765 encrypted MAC) would be communicated to the 205-based system.
[00354] [00354] In alternative aspects, the key used to encrypt the generator's unencrypted data (for example, Figure 25 and Figure 26) or the generator's unencrypted data and the MAC (for example, Figure 27) can be different from the key (for example, keys 3746, 3756, 3766) used to produce the MAC. For example, the key used to encrypt the generator's unencrypted data (for example, Figure 25 and Figure 26) or the generator's unencrypted data and the MAC (for example, Figure 27) can be a different shared secret or a public key associated with the recipient.
[00355] [00355] Instead of using the MAC to provide a subsequent guarantee of data integrity to the cloud-based system 205, according to other aspects, the central surgical controller 206 can use a digital signature to enable the system based on 205 cloud subsequently authenticates the integrity of the reported generator data. For example, processor module 232 and / or processor 244 of computer system 210 may use one or more algorithms to generate a digital signature associated with the generator data, and the cloud-based system 205 may use an algorithm to determine the authenticity of the data received from the generator. The algorithms used by the process module
[00356] [00356] In accordance with other aspects of the present description, the central surgical controller 206 may use a commercial authentication program (for example, Secure Hash Algorithm (SHA-2 comprising SHA-256)) to provide a subsequent guarantee of integrity of the reported generator data for the 205 cloud-based system.
[00357] [00357] After the generator data has been encrypted (for example, through EtM, E&M, MtE), a component of the central surgical controller 206 can communicate the encrypted generator data to the cloud-based system 205. The component the central surgical controller 206 that communicates the encrypted generator data to the cloud-based system 205 can be, for example, processor module 232, a central surgical controller / a 207/209 center key modular communication module 203, router 211 of modular communication center 203, communication module 247 of computer system 210, etc.
[00358] [00358] According to several aspects, the communication of the encrypted generator data over the internet can follow an IP that: (1) defines datagrams that encapsulate the encrypted generator data to be delivered and / or (2) defines methods addresses that are used to label the datagram with the source and destination information.
[00359] [00359] According to several aspects, before the generator data is encrypted, the generator data can be stamped with date and time (if they have not already been stamped with date and time by the combined generator 3700) and / or the generator data can be compressed (if not already compressed by the combined generator 3700). The timestamp allows the 205-based system to correlate generator data with other data (for example, removed patient data) that can be communicated to the cloud-based system 205. Compression enables a smaller representation of the generator data to be subsequently encrypted and communicated to the cloud-based system 205. For compression, a component of the central surgical controller 206 can be used
[00360] [00360] Once the data generator and MAC of a given da- tagrama has been received in the cloud-based system 205 (for example Figure 25, reference 3748; Figure 26, 3758; and Figure 27, reference 3768), cloud-based system 205 can decrypt the generator data encrypted from the communicated datagram payload to obtain the communicated generator data.
[00361] [00361] In one aspect, again with reference to Figure 25, the recipient (for example, cloud-based system 205) can, similar to the central surgical controller 206, process the ciphertext 3744 using the same MAC algorithm using the same known / accessible secret key to produce an authenticating MAC. If the received MAC 3745 matches that authenticating MAC, the recipient (for example, cloud-based system 205) can safely assume that the ciphertext 3744 has not been altered and comes from the central surgical controller 206. The recipient (for example , cloud-based system 205) can then decrypt the ciphertext 3744 (for example, using key 3746) to obtain plain text 3742 (for example, data package comprising generator data).
[00362] [00362] In another aspect, with reference again to Figure 26, the recipient (for example, cloud-based system 205) can decrypt the ciphertext 3754 (for example, using the key 3756) to obtain the plain text 3752 (for example, data package comprising generator data). Then, similar to the central surgical controller 206, the recipient (for example, cloud-based system 205) can process the plain text 3752 through the same MAC algorithm using the same secret key known / accessible for produce an authenticating MAC. If the received MAC 3755 matches that authenticating MAC, the recipient (for example, cloud-based system 205) can safely assume that the ciphertext 3752 has not been altered and comes from the central surgical controller 206.
[00363] [00363] In yet another aspect, with reference again to Figure 27, the recipient (for example, cloud-based system 205) can decrypt the ciphertext 3764 (for example, through the key 3766) to obtain the plain text 3762 ( for example, data package comprising generator data) and MAC 3765. Next, similar to central surgical controller 206, the recipient (eg cloud-based system 205) can process plain text 3762 using the same MAC algorithm with the use of the same known / accessible secret key to produce an authenticating MAC. If the incoming MAC 3765 matches that authenticating MAC, the recipient (for example, cloud-based system 205) can safely assume
[00364] [00364] In alternative aspects, the key used to encrypt generator data not encrypted (for example, Figure 25 and Figure 26) or generator data unencrypted and the MAC (for example, Figure 27) may be different from the key (for example, keys 3746, 3756, 3766) used to produce the MAC. For example, the key used to encrypt the generator's unencrypted data (for example, Figure 25 and Figure 26) or the generator's unencrypted data and the MAC (for example, Figure 27) can be a different shared secret or key. public address associated with the recipient. In such respects, with reference to Figure 25, the recipient (for example, cloud-based system 205), after verifying MAC authentication using key 3746 (described above), can then decrypt the ciphertext 3744 (for example, through the different shared secrets or private key associated with the recipient) to obtain the plain text 3742 (for example, data package comprising the data generator). In such respects, with reference to Figure 26, the recipient can decrypt the 3754 ciphertext (for example, through the different shared secrets or private key associated with the recipient) to obtain the simple 3752 text (for example, packet of data that includes generator data), then verify the MAC authentication using key 3756 (described above). In such respects, with reference to Figure 27, the recipient can decrypt the 3764 ciphertext (for example, through the different shared secrets or private key associated with the recipient) to obtain the plain text 3762 (for example, data package that includes generator data), and MAC 3765 will then verify MAC authentication using key 3766 (described above).
[00365] [00365] In short, with reference to Figures 25 to 27, if a MAC authentication, as determined / calculated by the cloud-based system 205, is the same as the MAC that was received with the datagram, the system based on cloud 205 can be sure that the generator data received is authentic (ie, it is the same as the generator data that was communicated by the central surgical controller 206) and that the integrity of the data from the reported generator has not been compromised or altered. As described above, the recipient can additionally apply plain text 3742, 3752, 3762, or at least a portion of it, to the checksum function / algorithm (that is, used by the central surgical controller 206) to generate a validation checksum value in order to recheck the generator data integrity based on the checksum value stored in the communicated datagram header.
[00366] [00366] Additionally, based on the decrypted datagram, the source's IP address (for example, Figure 29, reference 3786) that originally communicated the datagram to the cloud-based system 205 can be determined from the communicated datagram header. If the source determined is a recognized source, the cloud-based system 205 can be sure that the generator data originates from a trusted source, thus providing origin authentication and further guaranteeing the integrity of the generator data. In addition, as each router through which the datagram passed on its way to the 205 cloud-based system includes its IP address with its forwarded communication, the 205 cloud-based system is able to track the trajectory followed by the datagram and identify each router that manipulated the datagram. The ability to identify the respective routers can be useful in cases where the content of the datagram received in the cloud-based system 205 is not the same as the content of the datagram as originally communicated by the central surgical controller 206. For aspects where the trajectory of communication was pre-specified and included in the header of the communicated datagram, the ability to identify the respective routers can enable the trajectory to be validated and provide additional security for the authenticity of the generator data received.
[00367] [00367] In addition, according to several aspects, after the authentication of the generator data received, the system based on number 205 can communicate a message (for example, a hadshake or similar message) to the surgical controller central 206 through the internet or another communication network, confirming / ensuring that the datagram communicated from the central surgical controller 206 was received intact by the cloud-based system 205, thus effectively closing the loop of that specific datagram.
[00368] [00368] Aspects of the communication method described above, and / or variations thereof, can also be used to communicate data in addition to generator data to the 205-based system and / or communicate generator data and / or other data from central surgical controller 206 for systems and / or devices in addition to the cloud-based system 205. For example, according to various aspects, generator data and / or other data can be communicated from the surgical controller control panel 206 for the handheld surgical device / instrument (eg wireless device / instrument 235), for a robotic interface of a surgical device / instrument (eg the robotic central surgical controller 222) and / or for other servers, including servers (for example, similar to server 213) associated with other cloud-based systems (for example, similar to the 205-based system), according to the communication method described above. For example, in certain cases, an EEPROM integrated circuit for a given surgical instrument may initially be supplied with only
[00369] [00369] In addition to communicating generator data to the cloud-based system 205, the central surgical controller 206 may also use the communication method described above, and / or variations thereof, to communicate data in addition to the data of the for the cloud-based system 205. For example, the central surgical controller 206 can also communicate other information associated with the surgical procedure to the cloud-based system 205. This other information may include, for example, the type of surgical procedure to be performed, the name of the facilities where the surgical procedure is being performed, the location of the facilities where the surgical procedure is being performed, an identification of the operating room within the facility where the procedure surgery is being performed, the name of the surgeon performing the surgical procedure, the age of the patient and the data associated with the patient's condition (eg blood pressure , heart rate, current medications). According to several aspects, this other information can be devoid of all information that could identify the specific surgery, patient or surgeon, so that the information is essentially anonymized for further processing and analysis by the cloud-based system 205 In other words, the data removed is not correlated to a specific surgery, patient or surgeon. Deprived information can be communicated to the cloud-based system 205 in conjunction with or separately from the reported generator data.
[00370] [00370] For cases in which the deprived / other data must be communicated separately from the generator data, the deprived / other data can be stamped with the date and time, compressed and / or encrypted in the same or different way as described above in relation to the generator data, and the central surgical controller 206 can be programmed / configured to generate a datagram that includes the unencrypted / other information in place of the encrypted generator data. The datagram can then be communicated from the central surgical controller 206 via the internet to the cloud-based system 205 following an IP that: (1) defines datagrams that encapsulate the encrypted generator data removed / other data to be and (2) define addressing methods that are used to identify the datagram with the source and destination information.
[00371] [00371] For cases in which the deprived / other information must be communicated separately from the generator data, the deprived / other data can be stamped with the date and time, compressed and / or encrypted in the same or different way as described above in relation to the generator data, and the central surgical controller 206 can be programmed / configured to generate a datagram that includes the encrypted generator data and the unencrypted / other information. An example of such a da- tagrama is shown in Figure 30, where the payload 3804 of the datagram is 3800 divided into two or more separate portions of payload data (for example, one for the encrypted generator data 3834, one for the unencrypted / other information 3836), with each portion having an identification bit (eg generator data (GD) 3806, other data (OD) 3812), the associated encrypted data 3808, 3814 and the associated filling 3810, 3816, if necessary, respectively. Additionally,
[00372] [00372] As presented above, it is a sad reality that the results of all surgical procedures are not always ideal and / or adequate. For cases where a failure event is detected and / or identified, a variation of the communication methods described above can be used to isolate surgical data that is associated with the failure event (for example, surgical data from the failure event) of surgical data that are not associated with the failure event (for example, surgical data of the non-failure event) and communicate the surgical data that are associated with the failure event (for example, failure event data) from the surgical controller central 206 for the cloud-based surgical system 205 in a prioritized manner for analysis. According to one aspect of the present description, the surgical data of the failure event are communicated from the central surgical controller 206 to the cloud-based system 205 in a prioritized manner in relation to the surgical data of the non-failure event.
[00373] [00373] Figure 31 illustrates various aspects of a method implemented by the system to identify surgical data associated with a failure event (for example, surgical data from the failure event) and communicate the surgical data identified for a surgical system based on 205 cloud in a prioritized way. The method comprises (1) receiving 3838 surgical data in a central surgical controller 206, the surgical data being associated with a surgical procedure; (2) stamping the 3840 date and time of the surgical data; (3) to identify 3842 a failure event associated with the surgical procedure; (4) determine 3844 which surgical data are associated with the failure event (for example, surgical data from the failure event); (5) separate 3846 data associated with the failure event from all other surgical data (for example, surgical data from the non-failure event) received in the central surgical controller 206; (6) placing the surgical data associated with the failure event in chronological order 3848; (7) encrypt 3850 surgical data associated with the failure event; and (8) communicate 3852 encrypted surgical data in a 205 cloud-based system in a prioritized manner.
[00374] [00374] More specifically, several surgical data can be captured during a surgical procedure and the surgical data captured
[00375] [00375] Once a failure event has been detected and / or identified (for example, which can be during or after the surgical procedure), the central surgical controller 206 can determine which surgical data are associated with the event of failure (for example, surgical data from the failure event) and which surgical data are not associated with the surgical event (for example, surgical data from the non-failure event). According to one aspect of the present description, a failure event can include, for example, a detection of one or more clamps erroneously fired during a stapling portion of a surgical procedure. For example, in one aspect, with reference to Figure 9, an endoscope 239 can take snapshots while a device / surgical instrument 235 comprises an end actuator including a staple cartridge performs a stapling portion of a procedure surgical. In such an aspect, an imaging module 238 can compare snapshots to stored images and / or images downloaded from the cloud-based system 205 that show clips correctly triggered for detection.
[00376] [00376] In some respects, a failure event is considered to cover a certain period of time, and all data associated with that certain period of time can be considered associated with the failure event.
[00377] [00377] After the surgical data associated with the failure event has been identified, the surgical data identified (for example, surgical data from the failure event) can be separated or isolated from all other surgical data associated with the surgical procedure (for example, surgical data from the non-failure event). The separation can be performed, for example, by marking or flagging the identified surgical data, storing the identified surgical data separately from all other surgical data associated with the surgical procedure, or storing only the other surgical data, continuing, at the same time, the processing of the identified surgical data for subsequent prioritized communication to the cloud-based system
[00378] [00378] The timestamp of all surgical data (for example, before or after surgical data is received at the central surgical controller) can be used by a component of the central surgical controller 206 to put in order chronologically identified surgical data associated with the failure event. The central surgical controller component 206 that uses the time stamp to chronologically identify the identified surgical data can be, for example, processor module 232, processor 244 of computer system 210 and / or combinations thereof . When placing surgical data in chronological order, the cloud-based system 205 and / or other interested parties can subsequently better understand the conditions that were present that led to the occurrence of the failure event and possibly identify the cause of the failure event, thereby providing the knowledge to possibly mitigate a similar failure event that may occur during a similar surgical procedure performed at a future date.
[00379] [00379] Once the surgical data has been placed in chronological order, the surgical data in chronological order can be encrypted in a similar way to that described above in relation to the encryption of the generator data. In this way, the identified surgical data can be encrypted to help ensure the confidentiality of the identified surgical data, while it is being stored in the central surgical controller 206 or while it is being transmitted to the 205-based system using the internet or other computer networks. According to several aspects, a component of the central surgical controller 206 uses an encryption algorithm to convert the identified surgical data from a readable version to a coded version, thus forming encrypted surgical data associated with the failure event (for example, Figures 25 to 27). The component of the central surgical controller using the encryption algorithm can be, for example, processor module 232, processor 244 of computer system 210 and / or combinations thereof. The encryption algorithm used can be a symmetric encryption algorithm or an asymmetric encryption algorithm.
[00380] [00380] After the identified surgical data has been encrypted, a component of the central surgical controller can communicate the encrypted surgical data associated with the failure event (eg, encrypted surgical failure event data) to the system based on cloud 205. The central surgical controller component that communicates encrypted surgical data to the cloud-based system 205 can be, for example, processor module 232, a central surgical controller / 207/209 key from the modular communication center 203, router 211 of the modular communication center 203 or communication module 247 of computer system 210. According to various aspects, the communication of encrypted surgical data (for example, surgical data from the failure) over the internet can follow an IP that: (1) defines datagrams that encapsulate the encrypted surgical data to be delivered, and (2) defines addressing methods which are used to mark the datagram with source and destination information. The datagram can be similar to the datagram shown in Figure 29 or the data shown in Figure 30, but it can be different in the sense that the header or payload of the datagram can include a field that includes a signal or a tag that identifies encrypted surgical data (for example, encrypted failure event surgical data) as being prioritized over other surgical data (for example, encrypted non-failure event surgical data). An example of such a datagram is shown in Figure 32, where the payload 3864 of datagram 3860 includes a field that indicates (for example, a prioritized designation 3834) that the payload 3864 includes prioritized surgical data (for example, data 3868 combined generator). According to several aspects, the payload 3864 of datagram 3860 can also include unmarked / unsigned / non-prioritized 3836 surgical data (for example, other surgical data 3874), as shown in Figure 32.
[00381] [00381] According to several aspects, before being encrypted, the identified surgical data (for example, surgical data from the failure event) can be compressed (if they have not already been compressed by the sources (or sources) of the relevant surgical data). Compression enables a smaller representation of the surgical data associated with the failure event to be subsequently encrypted and communicated to the cloud-based system 205. For compression, a component of the central surgical controller 206 can use a compression algorithm to convert a representation of the identified surgical data in a smaller representation of the identified surgical data, thus enabling more efficient and economical encryption of the identified surgical data (for example, less data to encrypt uses less processing resources) and more efficient communication and economic value of the surgical data identified
[00382] [00382] In cases where other non-prioritized surgical data (for example, surgical data from the non-failure event) must be reported to the prioritized surgical data (for example, surgical data from the failure event), the other surgical data are not prioritized data can be stamped with the date and time, compressed and / or encrypted in the same or different way as described above with respect to the surgical data identified as associated with a failure event (for example, surgical data of the failure event ), and the central surgical controller 206 can be programmed / configured to generate a datagram that includes the priority encrypted prioritized surgical data (for example, encrypted surgical failure event data) and the other unencrypted surgical data prioritized (for example, encrypted surgical failure event data). For example, in view of Figure 32, the payload 3864 of datagram 3860 can be divided into two or more distinct portions of payload data (for example, one for prioritized surgical data 3834, one for non-surgical data prioritized 3836), with each portion having an identification bit (eg generator data (GD) 3866, other data (OD) 3872), associated encrypted data (eg, prioritized surgical data
[00383] [00383] In some respects, once a failure event associated with a surgical procedure has been identified, the central surgical controller 206 and / or the cloud-based system 205 can subsequently mark or signal a surgical device / instrument 235 that was used during the surgical procedure as inoperative and / or re-

In one aspect, the reminder can be set to be provided / displayed periodically until an administrator can remove the signaling or marking of the surgical device / instrument 235 from the central surgical controller 206 and / or the cloud-based system
[00385] [00385] In various aspects of the present description, the central surgical controller 206 and / or cloud-based system 205 may want to control which components (eg surgical device / instrument 235, energy device 241) are being used in their interactive surgical system 100/200 to perform surgical procedures (for example, to minimize future failure events, to avoid the use of unauthorized or counterfeit components).
[00386] [00386] As such, in various aspects of the present description, since an interactive surgical system 100 can comprise a plurality of central surgical controllers 106, a cloud-based system 105 and / or each central surgical controller 106 of the surgical system interactive 100 may wish to track combinations of central surgical controller-components used over time. In one respect, when / after a component (see Figure 9, for example, surgical device / instrument 235, energy device
[00387] [00387] According to various aspects of the present description, the cloud-based system 105 and / or each central surgical controller 106 can use such registers / blocks to track the use of a specific component and / or a subcomponent until its use in the interactive surgical system 100. For example, if a specific component (eg surgical instrument / device 235) is flagged / marked as related to a failure event, the cloud-based system 105 and / or a central surgical controller 106 can analyze such registers / blocks to determine whether past use of that component and / or a subcomponent of that component contributed to or caused the failure event (e.g., overuse). In one example, the cloud-based system 105 may determine that a subcomponent (for example, end actuator) of that component may actually be contributing / causing the failure event and then flagging / signaling that component for inoperability and / or removal based on the determination.
[00388] [00388] According to another aspect, the cloud-based system 205 and / or the central surgical controller 206 can control which components (e.g. surgical device / instrument 235, energy device 241) are being used in a surgical system. interactive logic 200 to perform surgical procedures by authenticating the component and / or its supplier / manufacturer. In one respect, the supplier / manufacturer of a component can associate a serial number and origin ID with the component. In this respect, the supplier / manufacturer can create / generate a private key for the serial number, encrypt the serial number with the private key and store the serial number and source ID encrypted in an integrated circuit. (eg, memory) on the component before shipping to a surgical site. Here, by means of / after connecting the component to a central surgical controller 206, the central surgical controller 206 can read the serial number and origin ID from the electronic integrated circuit. In response, the central surgical controller 206 can send a message (ie, comprising the encrypted serial number) to a supplier / manufacturer server associated with the source ID (for example, directly or via the cloud-based system 205). In such an aspect, the central surgical controller 206 can encrypt the message using a public key associated with that supplier / manufacturer. In response, the central surgical controller 206 may receive a message (that is, comprising the supplier / manufacturer's private key generated for / associated with that encrypted serial number) from the supplier / manufacturer's server (for example, directly or through the cloud-based system 205). In such an aspect, the supplier / manufacturer's server can encrypt the message using a public key associated with the central surgical controller 206. In addition, in such an aspect, the central surgical controller 206 can then decrypt the message (for example, example, using a private key paired with the public key to encrypt the message) to reveal the private key associated with the encrypted serial number.
[00389] [00389] According to another aspect, the electronic integrated circuit of a component (for example, surgical device / instrument 235, energy device 241) can store (for example, in memory) data associated with the use of that component (ie usage data, eg number of uses with a limited use device, number of remaining uses, triggering algorithms performed,
[00390] [00390] Additional details are described in U.S. Patent Application publication No. 2017/0086914 entitled TECHNIQUES FOR OPE-
[00391] [00391] One of the functions of the central surgical controller 106 is to pair (also called in the present invention "connect" or "couple") with other components of the surgical system 102 to control, collect information from or coordinate interactions between components of the surgical system 102. Since the operating rooms of a hospital are likely to be in physical proximity to one another, a central surgical controller 106 of a surgical system 102 may inadvertently pair with components of a surgical system. 102 in a neighboring operating room, which could significantly interfere with the functions of the central surgical controller 106. For example, the central surgical controller 106 may accidentally activate a surgical instrument in a different operating room or record information from a procedure different continuous surgical procedure in a neighboring operating room.
[00392] [00392] Aspects of the present description present a solution, in which a central surgical controller 106 pairs only with detected devices of the surgical system 102 that are located within the limits of its operating room.
[00393] [00393] In addition, the central surgical controller 106 depends on its knowledge of the location of other components of the surgical system 102 within its operating room to make decisions on, for example, which surgical instruments should be paired with each other. others or activated. A change in the position of the central surgical controller 106 or another component of the surgical system 102 can be problematic.
[00394] [00394] Aspects of the present description additionally present a solution in which the central surgical controller 106 is configured to reassess or redetermin the limits of its operating room when detecting that the central surgical controller 106 has been moved. Aspect-
[00395] [00395] In several respects, a central surgical controller 106 is used with a surgical system 102 in a surgical procedure performed in an operating room. The central surgical controller 106 comprises a control circuit configured to determine the limits of the operating room, determine the devices of the surgical system 102 located within the limits of the operating room and pair the central surgical controller 106 with the devices of the system. surgical theme 102 located within the limits of the operating room.
[00396] [00396] In one aspect, the control circuit is configured to determine the limits of the operating room after activation of the central surgical controller 106. In one aspect, the central surgical controller 106 includes a communication circuit configured to detect tar and pair with the devices of the surgical system located within the limits of the operating room. In one aspect, the control circuit is configured to redetermin the limits of the operating room after a possible device in the surgical system 102 is detected. In one aspect, the control circuit is configured to periodically determine the limits of the operating room.
[00397] [00397] In one aspect, the central surgical controller 106 comprises an operating room mapping surgical that includes a plurality of non-contact sensors configured to measure the limits of the operating room.
[00398] [00398] In several aspects, the central surgical controller 106 includes a processor and a memory coupled to the processor. The memory stores instructions executable by the processor to pair the central surgical controller with devices from the surgical system 102 located within the limits of the operating room, as described above. In many respects, the present description provides a non-transitory, computer-readable medium that stores computer-readable instructions that, when executed, cause a machine to pair the central surgical controller 106 with surgical system devices 102 located within the operating room limits, as described above.
[00399] [00399] Figures 35 and 36 are logical flowcharts of processes representing control programs or logical configurations for the pairing of the central surgical controller 106 with devices of the surgical system 102 located within the limits of the operating room, as described above.
[00400] [00400] The central surgical controller 106 performs a wide range of functions that require short- and long-range communication, such as aid in a surgical procedure, coordination between devices in the surgical system 102 and data collection and transmission to the cloud 104. To properly perform its functions, the central surgical controller 106 is equipped with a communication module 130 capable of short-range communication with other devices of the surgical system 102. Communication module 130 is also capable of long-range communication with the a cloud
[00401] [00401] The central surgical controller 106 is also equipped with an operating room mapping module 133 which is capable of identifying the limits of an operating room and identifying devices of the surgical system 102 within the operating room. The central surgical controller 106 is configured to identify the limits of an operating room and to pair or connect only to possible devices in the surgical system 102 that are detected within the operating room.
[00402] [00402] In one aspect, the pairing comprises establishing a link or communication route. In another aspect, the pairing comprises establishing a link or control route.
[00403] [00403] An initial mapping or evaluation of the operating room boundaries occurs during an initial activation of the central surgical controller 106. In addition, the central surgical controller 106 is configured to maintain spatial recognition during the operation through the mapping your operating room, which can be useful in determining whether central surgical controller 106 has been moved. The 3017 revaluation can be performed periodically or can be triggered by an event such as the observation of a change in the devices of the surgical system 102 that are considered inside the operating room. In one aspect, the change is the 3010 detection of a new device that was not previously considered to be within the limits of the operating room, as shown in Figure 37. In another aspect, the change is a disappearance, disconnection or unpairing of a paired device that was previously considered to reside within the operating room, as shown in Figure 38. The central surgical controller 106 can continuously monitor the connection with the paired devices 3035 to detect 3034 missing, disconnected or not paired a paired device.
[00404] [00404] In other aspects, the events triggering the reevaluation may be, for example, changes in the positions of surgeons, changes in instrumentation or detection of a new set of tasks performed by the central surgical controller 106.
[00405] [00405] In one aspect, the evaluation of the room limits by the central surgical controller 106 is performed by activating a sensor matrix of the operating room mapping module 133 inside the central surgical controller 106 that allows it to detect the walls of the operating room.
[00406] [00406] Other components of the surgical system 102 can be made to have spatial recognition in the same or similar way as the central surgical controller 106. For example, a robotic central controller 122 can also be equipped with a control module. mapping of the operating room 133.
[00407] [00407] The spatial recognition of the central surgical controller 106 and its ability to map the operating room in relation to possible components of the surgical system 102 allows the central surgical controller 106 to make autonomous decisions on the possibility of including or excluding these possible components as part of the surgical system 102, which relieves the surgical team to deal with such tasks. In addition, the central surgical controller 106 is configured to make inferences about, for example, the type of surgical procedure to be performed in the operating room based on information collected before, during and / or after the performance of the procedure. - surgical treatment. Examples of information collected include the types of devices that are taken to the operating room, the time of introduction of such devices into the operating room and / or the sequence of activation devices.
[00408] [00408] In one aspect, the central surgical controller 106 employs the operating room mapping module 133 to determine the limits of the operating room (for example, an operating room or a fixed, mobile or temporary space ) with the use of measuring devices without ultrasonic or laser contact.
[00409] [00409] With reference to Figure 34, non-contact sensors based on ultrasound 3002 can be used to scan the operating room by transmitting an ultrasound explosion and receiving the echo when it jumps outside the perimeter of the walls. 3006 of an operating room to determine the size of the operating room and adjust the Bluetooth pairing distance limits. In one example, 3002 non-contact sensors can be Ping ultrasonic distance sensors, as shown in Figure 34.
[00410] [00410] Figure 34 shows how an ultrasonic sensor 3002 sends a brief hiss with its ultrasonic speaker 3003 and allows a microcontroller 3004 of the operating room mapping module 133 to measure how long the echo takes to return to the ultrasonic microphone of the ultrasonic sensor 3005. The microcontroller 3004 has to send a pulse to the ultrasonic sensor 3002 to start the measurement. The ultrasonic sensor 3002 then waits long enough for the microcontroller program to start a pulse input command. So, almost at the same time that the ultrasonic sensor 3002 sends out a 40 kHz hiss, it sends a loud signal to the 3004 microcontroller. When the ultrasonic sensor 3002 detects the echo with its 3005 ultrasonic microphone, it changes the signal high again down. The microcontroller microcontroller input command measures the time between the high and low changes and stores your measurement in a variable. This value can be used together with the speed of sound in the air to calculate the distance between the central surgical controller 106 and the wall of the operating room 3006.
[00411] [00411] In one example, as illustrated in Figure 33, a central surgical controller 106 can be equipped with four ultrasonic sensors 3002, each of the four ultrasonic sensors being configured to evaluate the distance between the cyclic controller central surgical 106 and an operating room wall 3000. Central surgical controller 106 can be equipped with more or less than four ultrasonic sensors 3002 to determine the limits of an operating room.
[00412] [00412] Other distance sensors can be used by the operating room mapping module 133 to determine the limits of an operating room. In one example, the operating room mapping module 133 can be equipped with one or more photoelectric sensors that can be used to assess the limits of an operating room. In one example, suitable laser distance sensors can also be employed to assess the limits of an operating room. Laser-based non-contact sensors scan the operating room by transmitting pulses of laser light, receiving pulses of laser light that hit the perimeter walls of the operating room and comparing the phase of the transmitted pulse to the received pulse to determine the operating room size and to adjust the Bluetooth pairing distance limits, for example.
[00413] [00413] With reference to the upper left corner of Figure 33, a central surgical controller 106 is placed in an operating room
[00414] [00414] In artificial real time 07:36:01, the operating room mapping module 133 employs ultrasonic distance sensors to ultrasonic ping the room (for example, send an ultrasound explosion and hear the echo when it hits the perimeter
[00415] [00415] In artificial real time 07:36:03, data is removed and stamped with date and time. In artificial real time 07:36:05, the central surgical controller 106 begins to pair the devices located only inside the operating room 3000, as verified with the use of ultrasonic distance sensors 3002 of the mapping module operating room 133. The upper right corner of Figure 33 illustrates several exemplifying devices that are within the limits of operating room 3000 and are paired with central surgical controller 106, including a secondary display device 3020, a secondary central controller 3021, a common interface device 3022, a stapler equipped with a 3023 motor, a video tower module 3024 and a handheld dissector equipped with a 3025 motor. On the other hand, the secondary central controller 3021 ', the secondary display 3020 'and the stapler equipped with a 3026 engine are all outside the limits of the operating room 3000 and, consequently, are not paired with the ciru controller central logic 106.
[00416] [00416] In addition to establishing a communication link with the devices of the surgical system 102 that are inside the operating room, the central surgical controller 106 also assigns a unique sequence or number of communication and identification to each of the devices. - you. The unique string can include the device name and a timestamp when the communication was first established. Other appropriate device information can also be incorporated into the device's unique sequence.
[00417] [00417] As shown in the upper left corner of Figure 33, the central surgical controller 106 determined that the limits of the operating room 3000 are at distances a, -a, b and -b from the central surgical controller 106. As the device "D" it is outside the determined limits of its operating room 3000, the central surgical controller 106 does not match the device "D". Figure 35 is an example of an algorithm illustrating how the central surgical controller 106 pairs only with devices within the limits of its operating room. After activation, the central surgical controller 106 determines 3007 the limits of the operating room using the operating room mapping module 133, as described above. After the initial determination, the central surgical controller 106 continuously searches for or detects 3008 devices within a matching range. If a device is detected 3010, the central surgical controller 106 then determines 3011 whether the detected device is within the limits of the operating room. The central surgical controller 106 pairs 3012 with the device if it is determined that the device is within the limits of the operating room. In certain cases, the central surgical controller 106 will also assign 3013 an identifier to the device. If, however, the central surgical controller 106 determines that the detected device is outside the limits of the operating room, the central surgical controller 106 ignores the device 3014.
[00418] [00418] With reference to Figure 36, after an initial determination of the limits of the room and after an initial pairing of the devices located within those limits, the central surgical controller 106 continues to detect 3015 new devices that become available for pairing. If a new device is detected 3016, the central surgical controller 106 is configured to re-evaluate 3017 the limits of the operating room before pairing with the new device. If it is determined that the new device 3018 is within the recently determined limits of the operating room, then the central surgical controller 106 pairs with the device
[00419] [00419] For pairing, the operating room mapping module 133 contains an integrated Bluetooth compass and transceiver. Other communication mechanisms, which are not significantly affected by the hospital environment or geographic location, can be employed. Bluetooth low energy ("BLE") Bluetooth radio beacon technology can currently obtain indoor distance measurements with an accuracy of about 1 to 2 meters, with improved accuracy in more proactive positions. (0 to 6 meters). To improve the accuracy of distance measurements, a compass is used with the BLE. The operating room mapping module 133 uses the BLE and the compass to determine where the modules are located in relation to the patient. For example, two modules facing each other (detected by the compass) more than one meter apart can clearly indicate that the modules are on opposite sides of the patient. The more modules activated by the central controller that resides in the operating room, the greater the precision obtained due to triangulation techniques.
[00420] [00420] In situations where multiple central surgical controllers 106 and / or other peripherals are present in the same operating room, as shown in the upper right corner of Figure 33, the operating room mapping module 133 is configured to map the location of each module that resides inside the operating room. This information could be used by the user interface to display a virtual map of the room, allowing the user to more easily identify which modules are present and enabled, as well as their current situation. In one aspect, the mapping data collected by the central surgical controllers 106 is sent to the cloud 104, where the data is analyzed to identify how an operating room is physically configured, for example.
[00421] [00421] The central surgical controller 106 is configured to determine a location of the device by evaluating the transmission of the radio signal intensity and signal direction. For Bluetooth protocols, the received signal strength indication ("RSSI") is a measurement of the received radio signal strength. In one aspect, the devices of the surgical system 102 can be equipped with USB Bluetooth adapters. Central surgical controller 106 can scan the USB Bluetooth radio beacon for distance information. In another aspect, multiple high-gain antennas on a Bluetooth access point with variable attenuators can produce more accurate results than RSSI measurements. In one aspect, the central surgical controller is configured to determine the location of a device by measuring the signal strength of multiple antennas. Alternatively, in some examples, the central surgical controller 106 can be equipped with one or more motion sensor devices configured to detect a change in the position of the central surgical controller 106.
[00422] [00422] With reference to the lower left corner of Figure 33, the central surgical controller 106 has been moved from its original position, which is shown in dashed lines, to a new position closer to device "D" which is still outside the limits of the operating room 3000. Central surgical controller 106 in its new position, and based on the limits previously determined in the operating room, would naturally conclude that device "D" is a possible component of the surgical system 102. However , the introduction of a new device is a triggering event for a 3017 reassessment of the operating room limits
[00423] [00423] In one aspect, one or more of the processes shown in Figures 35 to 39 can be performed by a control circuit of a central surgical controller 106, as shown in Figure 10 (processor 244). In another aspect, one or more of the processes shown in Figures 35 to 39 can be performed by a cloud computing system 104, as shown in Figure 1. In yet another aspect, one or more among the The processes shown in Figures 35 to 39 can be performed by at least one of the aforementioned cloud computing systems 104 and / or a control circuit of a central surgical controller 106 in combination with a control circuit of a modular device, such as the microcontroller 461 of the surgical instrument depicted in Figure 12, microcontroller 620 of the surgical instrument depicted in Figure 16, the control circuit 710 of the robotic surgical instrument shown 700 in Figure 17, the control circuit 760 of surgical instruments 750, 790 shown in Figures 18 and 19 or the controller 838 of the generator 800 shown in Figure 20. Spatial recognition of the central surgical controllers in the operating rooms
[00424] [00424] During a surgical procedure, a surgical instrument, such as an ultrasonic or RF surgical instrument, can be attached to a generator module 140 of the central surgical controller 106. In addition, a separate surgical instrument controller
[00425] [00425] Aspects of the present description are presented for a central surgical controller 106 configured to establish and separate the pairings between the components of the surgical system 102 within the limits of the operating room to coordinate the flow of information and the control actions between such components. The central surgical controller 106 can be configured surgically to establish a pairing between a surgical instrument controller and a surgical instrument that reside within the confines of an operating room of the central surgical controller 106.
[00426] [00426] In several aspects, the central surgical controller 106 can be configured to establish and separate the pairings between the components of the surgical system 102 based on the operator's request and the situational and / or spatial recognition. The central controller's situational recognition is described in more detail below in connection with Figure 62.
[00427] [00427] Aspects of the present description are presented for a central surgical controller for use with a surgical system in a surgical procedure performed in an operating room. The central surgical controller includes a control circuit that forms and separates
[00428] [00428] In addition to the above, in one aspect, the control circuit is additionally configured to pair the central surgical controller with a third device of the surgical system, assign a third identifier to the third device, separate the pairing between the first device and the second device and selectively pair the first device with the third device. In one aspect, the control circuit is further configured to store an indicative record of the pairing between the first device and the third device on the storage media. In one aspect, the pairing between the first device and the third device defines a communication route between them. In one aspect, the pairing between the first device and the third device defines a control route for transmitting control actions from the third device to the first device.
[00429] [00429] In several aspects, the central surgical controller includes a processor and a memory attached to the processor. The memory stores instructions executable by the processor to selectively form and separate pairs between devices in the surgical system, as described above. In several respects, the present description provides a non-transient, computer-readable medium that stores computer-readable instructions that, when executed, cause a machine to selectively form and separate pairs between devices in the surgical system, as described above. Figures 40 and 41 are logical flowcharts of processes representing control programs or logical configurations to selectively form and separate pairings between devices in the surgical system, as described above.
[00430] [00430] In one aspect, the central surgical controller 106 establishes a first pairing with a surgical instrument and a second pairing with the surgical instrument controller. The central surgical controller 106 then links the pairings allowing the surgical instrument and the surgical instrument controller to operate with each other. In another aspect, the central surgical controller 106 can separate an existing communication link between a surgical instrument and a surgical instrument controller, then connect the surgical instrument to another surgical instrument controller that is connected to the central surgical controller 106.
[00431] [00431] In one aspect, the surgical instrument controller is paired with two sources. First, the surgical instrument controller is paired with the central surgical controller 106, which includes generator module 140 to control its activation. Second, the surgical instrument controller is also paired with a specific surgical instrument to prevent inadvertent activation of the wrong surgical instrument.
[00432] [00432] With reference to Figures 40 and 42, the central surgical controller 106 can cause the communication module 130 to tie 3100 or establish a first communication link 3101 with a first device 3102 of the surgical system 102, which can be a first surgical instrument. Then, the central surgical controller 3104 can assign a first identification number to the first device
[00433] [00433] In addition, the central surgical controller 106 can then cause communication module 130 to pair 3106 or establish a second communication link 3107 with a second device 3108 of surgical system 102, which can be a surgical instrument controller. Central surgical controller 106 then assigns 3110 to a second identification number for second device 3108.
[00434] [00434] In several respects, the steps of pairing a central surgical controller 106 with a device may include detecting the presence of a new device, determining that the new device is within the limits of the operating room, as described in more detail above, and pairing only with the new device, if the new device is located within the confines of the operating room.
[00435] [00435] The central surgical controller 106 can then stack 3112 or allow a communication link 3114 to be established between the first device 3102 and the second device 3108, as illustrated in Figure 42. An indicative record of the en - communication lace 3114 is stored by the central surgical controller 106 in the storage matrix 134. In one aspect, the
[00436] [00436] Referring to Figures 41 and 43, the central surgical controller 106 can then detect and pair 3120 or establish a third communication link 3124 with a third device 3116 of surgical system 102, which can be another central surgical controller , for example. The central surgical controller 106 can then assign 3126 a third identification number to the third device 3116.
[00437] [00437] In certain respects, as shown in Figure 43, the central surgical controller 106 can then pair 3130 or allow a communication link 3118 to be established between the first device 3102 and the third device 3116, while making that the communication link 3114 is separated 3128, as illustrated in Figure 43. A record indicating the formation of the communication link 3118 and separation of the communication link 3114 is stored by the central surgical controller 106 in the storage matrix 134. In one aspect, the communication link 3118 is established through the central surgical controller 106. In another aspect, as illustrated in Figure 43, the communication link 3118 is a direct link between the first device 3102 and the third device 3116 .
[00438] [00438] As described above, the central surgical controller 106 can manage indirect communication between devices in the surgical system 102. For example, in situations where the first device 3102 is a surgical instrument and the second device 3108 is an instrument controller surgical, an output from the surgical instrument controller can be transmitted via the communication link 3107 to the central surgical controller 106, which can then transmit the output to the surgical instrument via the communication link 3101.
[00439] [00439] When making a decision to connect or separate a connection between devices in the surgical system 102, the central surgical controller 106 may depend on the perioperative data received or generated by the central surgical controller 106. Perioperative data includes operator input data , situational recognition of the central controller, spatial recognition of the central controller and / or cloud. For example, a request can be transmitted to the central surgical controller 106 from an operator user interface to assign a surgical instrument controller to a surgical instrument. If the central surgical controller 106 determines that the surgical instrument controller is already connected to another surgical instrument, the central surgical controller 106 can separate the connection and establish a new connection at the operator's request.
[00440] [00440] In certain examples, the central surgical controller 106 may establish a first communication link between the display system 108 and the primary screen 119 to transmit an image, or other information, from the display system 108, which it resides outside the sterile field, to the main screen 119, which is located inside the sterile field. The central surgical controller 106 can then separate the first communication link and establish a second communication link between a robotic central surgical controller 122 and the main screen 119 to transmit another image, or other information, from the controller robotic central surgical 122 for main screen 119, for example. The ability of the central surgical controller 106 to assign and reassign the main screen 119 to different components of the surgical system 102 allows the central surgical controller 106 to manage the flow of information within the operating room, particularly between components within the sterile field and outside of the sterile field, without physically moving these components.
[00441] [00441] In another example involving situational recognition of the central controller, the central surgical controller 106 can selectively connect or disconnect devices from the surgical system 102 within an operating room based on the type of surgical procedure being performed or based on a determination of a next step in the surgical procedure that requires devices to be connected or disconnected. Situational recognition of the central controller is described in more detail below in connection with Figure 62.
[00442] [00442] With reference to Figure 44, the central surgical controller 106 can track 3140 the progression of the surgical steps in a surgical procedure and can coordinate the pairing and performance of the devices of the surgical system 102 based on such progression. For example, the central surgical controller 106 may determine that a first surgical step requires the use of a first surgical instrument, while a second surgical step, which occurs after the completion of the first surgical step, requires the use of a se - second surgical instrument. Consequently, the central surgical controller 106 can assign a surgical instrument controller to the first surgical instrument over the duration of the first surgical step. After detecting the 3142 completion of the first surgical step, the central surgical controller 106 can cause the communication link between the first surgical instrument and the surgical instrument controller to be separated 3144. The central surgical controller 106 can then , assign the surgical instrument controller to the second surgical instrument by pairing 3146, or authorize the establishment of a communication link between the surgical instrument controller and the second surgical instrument.
[00443] [00443] Several other examples of situational recognition of the central controller, which can influence the decision to connect or disconnect devices from the surgical system 102, are described in more detail below in connection with Figure 62.
[00444] [00444] In certain aspects, the central surgical controller 106 can use its spatial recognition capabilities, as described in more detail elsewhere in the present invention, to track the progression of the surgical stages of a surgical procedure and autonomously reassigning a surgical instrument controller from one surgical instrument to another surgical instrument within the operating room of the central surgical controller 106. In one aspect, the central surgical controller 106 uses Bluetooth pairing information and compass to determine undermine the physical position of the components of the surgical system 102.
[00445] [00445] In the example illustrated in Figure 2, the central surgical controller 106 is paired with a first surgical instrument held by a surgical operator on the operating table and a second surgical instrument positioned on a side tray. A surgical instrument controller can be selectively paired with the first surgical instrument or the second surgical instrument. Using the pairing information by Bluetooth and compass, the central surgical controller 106 automatically assigns the surgical instrument controller to the first surgical instrument due to its proximity to the patient.
[00446] [00446] After the completion of the surgical step that involved the use of the first surgical instrument, the first surgical instrument can be returned to the side tray or, otherwise, moved in the opposite direction to the patient. Upon detecting a change in the position of the first surgical instrument, the central surgical controller 106 can separate the communication link between the first cyclic instrument
[00447] [00447] In several respects, surgical system devices 102 are equipped with an easy control transfer operation mode that would allow a user to provide activation control of a device he currently controls to another surgical instrument controller within range. another operator. In one aspect, the devices are equipped to perform the transfer of control through a predetermined activation sequence of the devices that cause the devices that are activated in the predetermined activation sequence to pair with each other.
[00448] [00448] In one aspect, the activation sequence is performed by energizing the devices to be paired with each other in a specific order. In another aspect, the activation sequence is carried out by energizing the devices to be paired with each other within a predetermined period of time. In one aspect, the activation sequence is carried out by activating communication components, such as Bluetooth, of the devices to be paired with each other in a specific order. In another aspect, the activation sequence is carried out by activating communication components, such as Bluetooth, of the devices to be paired with each other within a predetermined period of time.
[00449] [00449] Alternatively, the transfer of control can also be performed by selecting a device through one of the devices.
[00450] [00450] In several aspects, the central surgical controller 106 can be configured to directly identify components of the surgical system 102, as they are placed in an operating room. In one aspect, the devices of the surgical system 102 can be equipped with an identifiable identifier by the central surgical controller 106, such as, for example, a bar code or a radio frequency identification tag ("RFID" - Radio- Frequency Identification). Proximity field communication ("NFC" - Near Field Communication) can also be used. The central surgical controller 106 can be equipped with a surgical reader or scanner suitable for detecting devices placed in the operating room.
[00451] [00451] Central surgical controller 106 can also be configured to check and / or update various control programs for surgical system devices 102. Upon detecting and establishing a communication link from a surgical system memory device 102 , the central surgical controller 106 can verify that its control program is up to date. If central surgical controller 106 determines that a newer version of the control program is available, central surgical controller 106 can download the latest version from cloud 104 and can update the device to the latest version. Central surgical controller 106 can issue a sequential identification and communication number for each paired or connected device. Cooperative use of data derived from secondary sources by intelligent central surgical controllers
[00452] [00452] In a surgical procedure, the attention of a surgical operator must be focused on the immediate tasks. Receiving information from multiple sources, such as multiple monitors, while useful, can also be distracting. The imaging module 138 of the central surgical controller 106 is configured to collect, analyze, organize / prepare and intelligently disseminate information relevant to the surgical operator in a way that minimizes distractions.
[00453] [00453] Aspects of the present description are presented for the cooperative use of data resulting from multiple sources, such as, for example, an imaging module 138 of the central surgical controller 106. In one aspect, imaging module 138 is configured for superimpose data derived from one or more sources to a live stream intended for main screen 119, for example. In one aspect, the overlapping data can be derived from one or more frames captured by the imaging module 138. The imaging module 138 can take picture frames on the way for display on a local screen, for example, the main screen 119. Imaging module 138 also comprises an image processor that can preform a local image processing matrix into the appropriate images.
[00454] [00454] In addition, a surgical procedure, in general, includes several surgical tasks that can be performed by one or more surgical instruments guided by a surgical operator or a surgical robot, for example. The success or failure of a surgical procedure depends on the success or failure of each surgical task. Without relevant data on individual surgical tasks, determining the reason for a failed surgical procedure is a matter of probability.
[00455] [00455] Aspects of the present description are presented to capture one or more frames of a live transmission of a surgical procedure for further processing and / or pairing
[00456] [00456] In one aspect, one or more captured images are used to identify at least one surgical task completed previously to evaluate the result of the surgical task. In one aspect, surgical task is a tissue stapling task. In another aspect, the surgical task is a transection with advanced energy.
[00457] [00457] Figure 45 is a logical flow chart of a 3210 process that represents a control program or a logical configuration to superimpose information derived from one or more static frames from a live transmission from a remote surgical site to the live mission. The 3210 process includes receiving 3212 a live transmission from a remote surgical site from a medical imaging device 124, for example, capturing 3214 at least one picture of a surgical step in the surgical procedure from the live transmission, derive 3216 the relevant information for the surgical stage from data extracted from at least one image frame and superimpose 3218 the information on the live transmission.
[00458] [00458] In one aspect, the static pictures can be from a surgical stage performed at the remote surgical site. Static charts can be analyzed for information regarding the completion of the surgical stage. In one aspect, the surgical step involves stapling the tissue at the surgical site. In another aspect, the surgical task involves applying energy to the tissue at the surgical site.
[00459] [00459] Figure 46 is a logical flow chart of a 3220 process that represents a control program or a logical configuration to differentiate the surgical steps from a surgical procedure. The 3220 process includes receiving 3222 a live transmission from a surgical site from a medical imaging device 124, for example, capturing 3224 at least a first image frame from a first surgical step of the surgical procedure from the live transmission , derive 3226 information relevant to the first surgical step from data extracted from at least one image frame, capture 3228 at least a second image frame from a second surgical step of the surgical procedure from live transmission and differentiate 3229 between the first surgical step and the second surgical step based on at least a first image frame and at least a second image frame.
[00460] [00460] Figure 47 is a logical flow chart of a 3230 process that represents a control program or a logical configuration to differentiate between the surgical steps of a surgical procedure. The 3232 process includes receiving 3232 a live transmission from the surgical site from a medical imaging device 124, for example, capturing 3234 image frames of the surgical stages of the surgical procedure from the live transmission and differentiating 3236 between the surgical steps based on data extracted from the image frames.
[00461] [00461] Figure 48 is a logical flowchart of a 3240 process that represents a control program or a logical configuration for identifying a staple cartridge from information derived from one or more static frames of staples implanted from the cartridge staples in the fabric. The 3240 process includes receiving a live 3242 transmission from the surgical site from the medical imaging device 124, for example, capturing a 3244 image frame.
[00462] [00462] In several aspects, one or more of the steps of the 3210, 3220, 3230, 3240 processes can be performed by a control circuit of an imaging module of a central surgical controller, as represented in Figures 3, 9, 10. In certain examples, the control circuit may include a processor and memory attached to the processor, the memory storing instructions executable by the processor to perform one or more of the process steps 3210, 3220, 3230, 3240. In certain examples - plos, a non-transitory, computer-readable medium stores computer-readable instructions that, when executed, cause a machine to perform one or more of the steps of processes 3210, 3220, 3230, 3240. For simplicity, the following description of processes 3210, 3220, 3230, 3240 will be described as being executed by the control circuit of an imaging module of a central surgical controller; however, it must be understood that the execution of processes 3210, 3220, 3230, 3240 can be performed by any of the above examples.
[00463] [00463] With reference to Figures 34 and 49, a central surgical controller 106 is in communication with a medical imaging device 124 located in a remote surgical site during a surgical procedure. The imaging module 138 receives a live transmission from the remote surgical site transmitted by the imaging device 124 to a main screen 119, for example, according to steps 3212, 3222, 3232, 3242.
[00464] [00464] In addition to the above, the imaging module
[00465] [00465] In one aspect, the derived information can be superimposed on the live broadcast. In one aspect, static frames and / or information resulting from processing static frames can be communicated to a cloud 104 for data aggregation and further analysis.
[00466] [00466] In several respects, the 3200 frame capture device may include a digital video decoder and memory to store the captured static frames, such as a frame buffer. The 3200 frame capture device can also include a bus interface through which a processor can control capture and access data and general purpose I / O to trigger image capture or control external equipment.
[00467] [00467] As described above, imaging device 124 may be in the form of an endoscope, including a camera and a light source positioned at a remote surgical site and configured to provide a live broadcast of the remote surgical site on the main screen - pal 119, for example.
[00468] [00468] In several respects, image recognition algorithms can be implemented to identify resources or objects in static frames of a surgical site that are captured by the 3200 frame capture device. Useful information related to the surgical steps associated with the Captured frames can be derived from the identified resources. For example, the identification of staples in the captured frames indicates that a surgical step of stapling tissue was performed at the surgical site. The type, color, layout and size of the identified staples can also be used to derive useful information about the staple cartridge and the surgical instrument used to implant the staples. As described above, this information can be superimposed on a live broadcast directed to a main screen 119 in the operating room.
[00469] [00469] Image recognition algorithms can be performed at least in part locally by computer platform 3203 (Figure 49) of imaging module 138. In certain cases, image recognition algorithms can be performed at least in part by processor module 132 of central surgical controller 106. An image database can be used in the performance of image recognition algorithms and can be stored in a 3202 memory of the 3203 computer platform. Alternatively , the imaging database can be stored in the storage matrix 134 (Figure 3) of the central surgical controller 106. The image database can be updated from cloud 104.
[00470] [00470] An exemplary image recognition algorithm that can be executed by the computer platform 3203 can
[00471] [00471] With reference to Figures 50 to 52, in one example, a surgical step involves stapling and cutting the tissue. Figure 50 represents a static frame 3250 of stapled and cut T fabric. A 3252 staple implant includes the 3252 ', 3252 "staples from a first staple cartridge. A second 3254 staple implant includes 3254', 3254 staples "of a second staple cartridge. A proximal portion 3253 of the staple implant 3252 overlaps a distal portion 3255 of the staple implant 3254. Six rows of staples were positioned in each implant. The T fabric was cut between the third and fourth rows of each implant, but only one side of the stapled T fabric is fully shown.
[00472] [00472] In several aspects, the imaging module 138 identifies one or more of the clips 3252 ', 3252 ", 3254', 3254" the static frame 3250, which were absent in a previous static frame captured by the capture device. table 3200. Imaging module 138 then concludes that a surgical cutting and stapling instrument was used at the surgical site.
[00473] [00473] In the example in Figure 50, the staple 3252 implant includes two different staples 3252 ', 3252 ". Likewise, the 3254 staple implant includes two different staples 3254', 3254". For the sake of brevity, the following description focuses on clamps 3252 ', 3252 ", but is equally applicable to clamps 3254', 3254". Staples 3252 ', 3252 "are arranged in a pattern or predetermined sequence that forms a unique identifier corresponding to the staple cartridge that housed staples 3252', 3252". The exclusive pattern can be in a single row or in multiple rows of the 3250 clips. In one example, the exclusive pattern can be obtained by alternating the clips 3252 ', 3252 "in a predetermined arrangement.
[00474] [00474] In one aspect, multiple patterns can be detected in one shot of the clips. Each pattern can be associated with a unique characteristic of the staples, the staple cartridge that housed the staples and / or the surgical instrument that was used to trigger the staple. For example, a shot of the clips may include patterns that represent the shape of the clip, the size of the clip and / or the location of the shot.
[00475] [00475] In the example in Figure 50, imaging module 138 can identify a unique pattern for 3252 staples from the static frame 3250. A database that stores staple patterns and corresponding identification numbers for staple cartridges can then , be exploited to determine a staple cartridge identification number that housed staples
[00476] [00476] The patterns in the example in Figure 50 are based on just two different clips; however, other aspects may include three or more different clips. The different clips can be coated with different coatings, which can be applied to the clips by one or more of the following methods: anodizing, coloring, electro-coating, photoluminescent coating, nitride application, methyl methacrylate, painting, powder coating , paraffin coating, oily stains or phosphorescent coatings, the use of hydroxyapatite, polymers, titanium oxynitrides, zinc sulphides, carbides, etc. It should be noted that, while the coatings mentioned are reasonably specific, as described herein, other coatings known in the art for distinguishing the clamp are contemplated within the scope of the present description.
[00477] [00477] In the example of Figures 50 to 52, clips 3252 'are anodized clips, while clips 3252 "are non-anodized clips. In one aspect, different clips can comprise two or more different colors. Different metal clips can comprise markers magnetic or radioactive clips that differentiate them from unmarked clips.
[00478] [00478] Figure 51 illustrates an implantation of staple 3272 implanted in the tissue from a staple cartridge using a surgical instrument. Only three rows of staples 3272a, 3272b, 3272c are shown in Figure 51. Rows 3272a, 3272b, 3272c are arranged between a central line, where the fabric has been cut, and a lateral line at the edge of the fabric. For clarity, the internal staple file 3272a is redesigned separately on the left and the two external rows 3272b, 3272c are redesigned separately on the right. A 3273 proximal end and a distal end portion of the 3272 staple implant are also redesigned in Figure 51 for clarity.
[00479] [00479] Staple implant 3272 includes two different staples 3272 ', 3272 "which are arranged in predetermined patterns that serve various functions. For example, the inner row 3272a comprises a pattern of alternating staples 3272', 3272" , which defines a metric for distance measurements in the surgical field. In other words, the inner row pattern 3272a acts as a ruler for measuring distances, which can be useful in accurately determining the position of a leak, for example. The outer rows 3272b, 3272c define a pattern representing an identification number of the staple cartridge that housed the staples 3272 ', 3272 ".
[00480] [00480] In addition, unique patterns at the ends of the 3272 staple implant identify the proximal end portion 3273 and the distal end portion 3275. In the example in Figure 51, a unique arrangement of three staples 3272 "identifies the distal end 3275, while a unique arrangement of four staples 3272 "identifies the proximal end 3273. The identification of the proximal and distal ends of a staple implant makes it possible to distinguish by the imaging module 128 from different staple deployments within a frame captured, which can be useful to indicate the source of a leak, for example.
[00481] [00481] In several respects, the imaging module 138 can detect a sealed tissue in a static frame of a surgical site captured by the 3200 frame capture device. Detection of the sealed tissue can be indicative of a surgical step that entails - revives the application of therapeutic energy to the tissue.
[00482] [00482] The sealing of the fabric can be done by applying
[00483] [00483] Consequently, the sealed fabric has a different color and / or shape that can be detected by the imaging module 138 with the use of image recognition algorithms, for example. In addition, smoke detection at the surgical site may indicate that the application of therapeutic energy to the tissue is underway.
[00484] [00484] In addition to the above, the imaging module 138 of the central surgical controller 106 is able to differentiate between the surgical steps of a surgical procedure based on the captured frames. As described above, a static frame comprising triggered clips is indicative of a surgical step involving stapling tissue, while a static frame comprising a sealed tissue is indicative of a surgical step involving the application of energy to the tissue.
[00485] [00485] In one aspect, the central surgical controller 106 can selectively override relevant information for a surgical task completed prior to live transmission. For example, overlapping information can comprise image data from a static picture of the surgical site captured during the previously completed surgical task. In addition, guided by common reference sites on the surgical site, imaging module 138 can interweave one image frame to another to establish and detect surgical sites and relationship data for a previously completed surgical task.
[00486] [00486] In one example, the central surgical controller 106 is configured to superimpose information regarding a potential leak in a tissue treated by stapling or applying therapeutic energy in a previously completed surgical task. The potential leak can be recognized by the imaging module 138 when processing a static frame of the tissue. The surgical operator can be alerted about the leak by overlapping information about the possible leak to the live broadcast.
[00487] [00487] In several respects, static pictures of a surgical instrument end actuator at a surgical site can be used to identify the surgical instrument. For example, the end actuator may include an identification number that can be recognized by the imaging module 138 during still frame image processing. Consequently, the static frames captured by the imaging module 138 can be used to identify a surgical instrument used in a surgical step of a surgical procedure. Static charts can also include useful information about the performance of the surgical instrument. All of this information can be sent to cloud 104 for data aggregation and further analysis.
[00488] [00488] In several examples, the central surgical controller 106 can also selectively overlay relevant information for a current or future surgical task, such as an anatomical site or a surgical instrument suitable for the surgical task.
[00489] [00489] Imaging module 138 can employ various edge and image detection techniques to track a surgical site when a surgical instrument has been used to complete a surgical task. The success or failure of the surgical task can then be assessed. For example, a surgical instrument can be used to seal and / or cut tissue at the surgical site. A static picture of the surgical site can be stored in memory 3202 or in the storage matrix 134 of the central surgical controller 106, for example, after the completion of the surgical task.
[00490] [00490] In the next surgical step, the quality of the seal can be tested through different mechanisms. To ensure that the test is applied accurately to the treated tissue, the stored static picture of the surgical site is superimposed on the live transmission in search of a match. When a match is found, testing can take place. One or more additional static frames can be obtained during the test, can be analyzed later by the imaging module 138 of the central surgical controller
[00491] [00491] Imaging module 138 can capture static frames of the response of the treated tissue for these tests, which can be stored in memory 3202 or in the storage matrix 134 of central surgical controller 106, for example. Static charts can be stored alone or in combination with other data, such as data from the surgical instrument that performed the tissue treatment. Paired data can also be uploaded to cloud 104 for further analysis and / or pairing.
[00492] [00492] In several respects, the static frames captured by the 3200 frame capture device can be processed locally.
[00493] [00493] In one aspect, the rate of frame capture may depend on the type of surgical task being performed. Certain surgical tasks may require a greater number of static frames than others for an assessment of success or failure. The frame rate can be scaled to accommodate such needs.
[00494] [00494] In one aspect, the frame capture rate is dependent on the detected movement of the imaging device 124. In use, an imaging device 124 can target a surgical site over a period of time. Observing no or small changes in the captured static frames while the imaging device 124 is not being moved, the imaging module 138 can reduce the frame capture rate of the 3200 frame capture device. If the situation however, where frequent motion is detected, imaging module 138 can respond by increasing the frame capture rate of frame capture device 3200. In other words, imaging module 138 can be configured to correlate the frame capture rate of the 3200 frame capture device with the degree of movement detected by the imaging device 124.
[00495] [00495] For more efficiency, only portions of the static frames, where movement is detected, need to be stored, processed and / or transmitted to the cloud 104. The image module 138 can be configured to select the portions of the static frames where movement is detected. In one example, motion detection can be achieved by comparing a static frame to a previously captured static frame. If motion is detected, imaging module 138 can cause the frame capture device 3200 to increase the frame capture rate, but only the portions where motion is detected are stored, processed and / or transmitted to the cloud. 104.
[00496] [00496] In another aspect, the data size can be managed by scaling the resolution of the captured information based on the area of the screen where the focal point is or where the end actuators are located, for example. The rest of the screen could be captured at a lower resolution.
[00497] [00497] In one aspect, the corners and edges of the screen can, in general, be captured at a lower resolution. The resolution, however, can be scaled if an event of importance is observed.
[00498] [00498] During a surgical procedure, the central surgical controller 106 can be connected to various monitoring devices in the operating room, such as, for example, heart rate monitors and insufflation pumps. The data collected from these devices can improve the situational recognition of the central surgical controller 106. The situational recognition of the central controller is described in more detail below in connection with Figure 62.
[00499] [00499] In one example, the central surgical controller 106 can be configured to use patient data received from a connected heart rate monitor together with data regarding the location of the surgical site to assess the proximity of the surgical site to the sensory nerves. An increase in the patient's heart rate, when combined with anatomical data indicating that the surgical site is in a region rich in sensory nerves, can be interpreted as an indication of proximity to the sensory nerve. Anatomical data can be made available to the central surgical controller 106 through access to patient records (for example, a PEP database containing patient records).
[00500] [00500] Central surgical controller 106 can be configured surgical to determine the type of surgical procedure to be performed on a patient from data received from one or more monitoring devices in the operating room, such as, for example , heart rate monitors and inflation pumps. Abdominal surgical procedures generally require abdominal inflation, while inflation is not necessary in theoretical surgery. Central surgical controller 106 can be configured to determine whether a surgical procedure is an abdominal or thoracic surgical procedure by detecting whether the insufflation pump is active. In one aspect, the central surgical controller 106 can be configured to monitor insufflation pressure on the outlet side of the insufflation pump to determine whether the surgical procedure being performed requires insufflation.
[00501] [00501] The central surgical controller 106 can also collect information from other secondary devices in the operating room to assess, for example, whether the surgical procedure is a vascular or avascular procedure.
[00502] [00502] Central surgical controller 106 can also monitor the supply of AC current to one or more of its components to assess whether a component is active. In one example, the central surgical controller 106 is configured to monitor the supply of AC power to the generator module to assess whether the generator is active, which may be an indication that the surgical procedure being performed is requires the application of energy to seal the fabric.
[00503] [00503] In several respects, secondary devices in the operating room that are unable to communicate with the central surgical controller 106 can be equipped with communication interface devices (communication modules) which can facilitate the pairing of these devices with the central surgical controller 106. In one aspect, the communication interface devices can be configured to connect the elements, allowing for a two-way communication between the central surgical controller 106 and such devices.
[00504] [00504] In one aspect, the central surgical controller 106 can be configured to control one or more operating parameters of a secondary device via a communication interface device. For example, the central surgical controller 106 can be configured to increase or decrease the inflation pressure through a communication interface device coupled to an inflation device.
[00505] [00505] In one aspect, the communication interface device can be configured to engage with a device interface port. In another aspect, the communication interface device may comprise an overlay or other interface that interacts directly with a control panel of the secondary device. In other respects, secondary devices, such as the heart rate monitor and / or inflation devices, can be equipped with integrated communication modules that allow them to pair with the central controller for bidirectional communication. - tional among them.
[00506] [00506] In one aspect, the central surgical controller 106 can also be connected via a communication interface device, for example, muscle patches that are connected to nerve stimulation detection devices to improve the resolution of a device. nerve detection.
[00507] [00507] In addition, the central surgical controller 106 can also be configured to manage supplies in the operating room. Different surgical procedures need different supplies. For example, two different surgical procedures may require different sets of surgical instruments. Certain surgical procedures may involve the use of a robotic system, while others do not. In addition, two different surgical procedures may require staple cartridges that are different in number, type and / or size. Consequently, supplies brought to the operating room can provide clues as to the nature of the surgical procedure to be performed.
[00508] [00508] In several aspects, the central surgical controller 106 can be integrated with an operating room supplies scanner to identify items brought into the operating room and introduced into the sterile field. Central surgical controller 106 can use data from the operating room supplies scanner, along with data from surgical system devices 102 that are paired with central surgical controller 106, to autonomously determine the type of surgical procedure that will be executed. In one example, central part 106 can record a list of smart cartridge serial numbers that will be used in the surgical procedure. During the surgical procedure, the central surgical controller 106 can gradually remove the clips that have been triggered, based on information collected from the integrated circuits of the staple cartridge. In one aspect, the central surgical controller 106 is configured to make sure that all items are accounted for at the end of the procedure. Control arrangements for the central surgical controller
[00509] [00509] In a surgical procedure, a second central surgical controller can be placed in an operating room already under the control of a first central surgical controller. The second central surgical controller can be, for example, a robotic central surgical controller placed in the operating room as part of a robotic system. Without coordination between the first and the second central surgical controllers, the central surgical controller will attempt to pair with all other components of surgical system 102 that are within the operating room. The confusion resulting from competition between the two central controllers in a single operating room can have undesirable consequences. In addition, the classification of instrument distribution among central controllers during the surgical procedure can be time-consuming.
[00510] [00510] Aspects of the present description are presented for a central surgical controller for use with a surgical system in a surgical procedure performed in an operating room. A control circuit of the central surgical controller is configured to determine the limits of the operating room and establish a control arrangement with a detected central surgical controller located within the limits of the operating room.
[00511] [00511] In one aspect, the control arrangement is an arrangement between peers. In another aspect, the control arrangement is a master-slave arrangement. In one aspect, the control circuit is configured to select one of a master operating mode or a slave operating mode in the master-slave arrangement. In one aspect, the control circuit is configured to deliver control of at least one surgical instrument to the central surgical controller detected in the slave operating mode.
[00512] [00512] In one aspect, the central surgical controller includes an operating room mapping surgery that includes a plurality of non-contact sensors configured to measure the limits of the operating room.
[00513] [00513] In several aspects, the central surgical controller includes a processor and a memory attached to the processor. The memory stores instructions executable by the processor to coordinate a control arrangement between central surgical controllers, as described above. In several respects, the present description provides a non-transitory, computer-readable medium that stores computer-readable instructions that, when executed, cause a machine to coordinate a control arrangement between central surgical controllers, as described above .
[00514] [00514] Aspects of the present description are presented for a surgical system that comprises two independent central surgical controllers that are configured to interact with each other. Each of the central surgical controllers has its own attached surgical device and the control and distribution designation from which the data is recorded and processed. This interaction causes one or both central surgical controllers to change their behavior from before the interaction. In one respect, the change involves a redistribution of devices previously assigned to each of the central surgical controllers. In another aspect, the change involves establishing a master-slave arrangement between central surgical controllers. In yet another aspect, the change may be a change in the processing location shared between central surgical controllers.
[00515] [00515] Figure 53 is a logical flowchart of a process that represents a control program or a logical configuration to coordinate a control arrangement between central surgical controllers. The process in Figure 53 is similar in many ways to the process in Figure 35 except that the process in Figure
[00516] [00516] Referring to Figure 54, a robotic central surgical controller 3300 enters an operating room is already occupied by a central surgical controller 3300. The robotic central surgical controller 3310 and central surgical controller 3300 are similar in many ways to other central surgical controllers described in more detail elsewhere in the present invention, such as, for example, central surgical controllers 106. For example, the 3310 robotic central surgical controller includes non-contact sensors configured to measure the limits of the operating room, as described in more detail elsewhere in the present invention in connection with Figures 33, 34.
[00517] [00517] When the robotic central surgical controller 3310 is triggered, it determines the limits of the operating room and begins to pair with other components of the surgical system 102 that are located within the limits of the operating room. The 3310 robotic central surgical controller pairs with a 3311 advanced robotic power tool, a 3312 robotic stapler, a 3313 monopolar power tool and a 3314 robotic display tower, all of which are located within the limits of the operating room. The central surgical controller 3300 is already paired with the hand stapler 3301, a dissector equipped with the hand motor 3302, a secondary screen 3303, a surgeon interface 3304 and a viewing tower 3305. Since the hand stapler 3301, the dissector equipped with a hand-held motor 3302, the secondary screen 3303, the surgeon interface 3304 and the viewing tower 3305 are already paired with the central surgical controller 3300, such devices cannot pair with another central surgical controller without permission of the 3300 central surgical controller.
[00518] [00518] In addition to the above, the central surgical controller 3310 detects and / or is detected by the central surgical controller
[00519] [00519] In the example of Figure 54, a master-slave arrangement is established. Central surgical controllers 3300, 3310 request permission from a surgical operator for the robotic central surgical controller 3310 to obtain control of the operating room from the central surgical controller 3300. Permission can be requested through an interface or surgeon console 3304. Once authorization is granted, central surgical controller 3310 requests that central surgical controller 3300 transfer the control to the robotic central surgical controller 3310.
[00520] [00520] Alternatively, the central surgical controllers 3300, 3310 can negotiate the nature of their interaction without external input
[00521] [00521] The result of the interaction between the central surgical controllers 3300, 3310 is illustrated on the right side of Figure 54. The central surgical controller 3300 transferred control to the central surgical controller 3310, which also obtained control of the surgical interface. - region 3304 and secondary screen 3303 of the central surgical controller
[00522] [00522] Figure 55 is a logical flowchart of a process that represents a control program or a logical configuration to coordinate a control arrangement between central surgical controllers. In several respects, two independent central surgical controllers will interact with one another in a predetermined manner to assess the nature of their relationship. In one example, after establishing a 3321 communication link, the controllers
[00523] [00523] The control disposition between the central surgical controllers is then determined 3323 based on the entry of a surgical operator or autonomously between the central surgical controllers. Central surgical controllers can store instructions on how to determine a control arrangement with each other. The control arrangement between two central surgical controllers may depend on the type of surgical procedure being performed. The control arrangement between two central surgical controllers may depend on their types, identification information and / or situation. The control arrangement between two central surgical controllers may depend on the devices paired with the central surgical controllers. The central surgical controllers then redistribute 3324 devices from surgical system 102 to each other based on the determined control arrangement.
[00524] [00524] In the master-slave arrangement, the registration communication can be unidirectional from the slave central controller to the master central controller. The master central controller may also require the central controller to transfer some of its wireless devices to consolidate communication routes. In one aspect, the slave central controller can be relegated to a retransmission configuration with the master central controller originating all commands and recording all data. The slave central controller can remain connected to the master central controller for a sub-
[00525] [00525] In a pairwise arrangement, each central surgical controller can retain control of its devices. In one aspect, central surgical controllers can collaborate to control a surgical instrument. In one aspect, a surgical instrument operator can designate the central surgical controller who will control the surgical instrument at the time of use.
[00526] [00526] With generic reference to Figures 56 to 61, the interaction between central surgical controllers can be extended beyond the limits of the operating room. In many ways, operating rooms in separate operating rooms can interact with each other within predefined limits. Depending on their relative proximity, central surgical controllers in separate operating rooms can interact via any wired or wireless data communication network, such as Bluetooth and WiFi. As used here, a "communication network" data "represents any number of physical, virtual or logical components, including hardware, software, firmware and / or processing logic configured to support data communication between a source component and a destination component, where data communication it is executed according to one or more communication protocols designated over one or more designated communication media.
[00527] [00527] In several aspects, a first surgical operator in a first operating room may wish to consult a second surgical operator in a second operating room, as in the case of an emergency. A temporary communication link can be established between the central surgical controllers in the first and second operating rooms to facilitate consultation while the first and second surgical operators remain in their respective operating rooms.
[00528] [00528] The surgical operator to be consulted can receive a consultation request through the central surgical controller in the operating room. If the surgical operator accepts, he will have access to all the data compiled by the central surgical controller requesting the consultation. The surgical operator can access all previously stored data, including a complete history of the procedure. In addition, a live transmission from the surgical site in the order operating room can be done via the central surgical controllers to a screen in the receiving operating room.
[00529] [00529] When a consultation request begins, the receiving central surgical controller begins to record all information received in a temporary storage location, which can be a dedicated portion of the central surgical controller's storage matrix. At the end of the consultation, the place of temporary storage is purged of all information. In one aspect, during a consultation, the central surgical controller records all accessible data, including data on blood pressure, ventilation, oxygen statistics, generator settings and uses, and all electronic patient data. There will probably be more data recorded than data stored by the central surgical controller during normal operation, which is useful to provide the surgical operator with as much information as possible for consultation.
[00530] [00530] With reference to Figure 56, a non-limiting example of an interaction between central surgical controllers in different operating rooms is shown. Figure 56 represents an OR 1 operating room that includes a 3400 surgical system that supports a thoracic segmentectomy and a second OR 3 operating room that includes a 3410 surgical system that supports a colorectal procedure. The 3400 surgical system includes the central surgical controller 3401, the central surgical controller 3402 and the robotic central surgical controller 3403. The surgical system 3400 additionally includes a personal interface 3406, a primary screen 3408 and secondary screens 3404, 3405. The system surgical 3410 includes a central surgical controller 3411 and a secondary screen 3412. For clarity, the various components of surgical systems 3400, 3410 are removed.
[00531] [00531] In the example in Figure 56, the OR 3 surgical operator is requesting an appointment from the OR 1 surgical operator. The OR 3 central surgical controller 3411 transmits the query request to one of the OR 1 central surgical controllers. , as the central surgical controller 3401. In OR 1, the central surgical controller 3401 presents the request on a personal interface 3406 made by the surgical operator. The consultation is about selecting an ideal location for a colon transection. The OR 1 surgical operator, through a 3406 personal interface, recommends an ideal location for the transection site that avoids a section of high colon vascularization. The recommendation is transmitted in real time via the central surgical controllers 3401, 3411. Consequently, the surgical operator is able to respond to the consultation request in real time without having to leave the sterile field of his own operating room. The surgical operator who requested the consultation also did not have to leave the sterile OR 3 field.
[00532] [00532] If the central surgical controller 3401 is not communicating with the personal interface 3406, it can transmit the message to another central surgical controller such as, for example, the central surgical controller 3402 or the robotic central surgical controller 3403. Alternatively , the central surgical controller 3401 can request control of the personal interface 3406 from another central surgical controller.
[00533] [00533] In any case, if the OR 1 surgical operator decides to accept the consultation request, a live transmission from a 3413 surgical site of the OR 3 colorectal procedure will be made to OR 1 through a connection established between the surgical controllers exchanges 3401, 3411, for example. Figure 57 illustrates a live transmission from surgical site 3413 displayed on a secondary OR 3 screen. Central surgical controllers 3401, 3411 cooperate to send live transmission from OR 3 surgical site to personal interface 3406 on OR 1 or as shown in Figure 58.
[00534] [00534] With reference to Figures 59 to 61, the surgical operator can expand the live transmission of OR 3 to the primary screen 3405 in OR 1, for example, through the controls of the personal interface 3406. The personal interface 3406 allows the surgical operator to select a destination for live transmission by presenting icons to the surgical operator representing the views that are available in OR 1, as shown in Figure 60. Other navigation controls 3407 are available for the surgical operator via personal interface 3406, as shown in Figure 61. For example, personal interface 3406 includes navigation controls to adjust live transmission from the OR 3 surgical site to OR 1 by the surgical operator by moving his fingers on the transmission live displayed on the personal interface
[00535] [00535] As illustrated in Figure 61, the surgical operator also
[00536] [00536] Situational recognition is the ability of some aspects of a surgical system to determine or infer information related to a surgical procedure from data received from databases and / or instruments. The information may include the type of procedure being performed, the type of tissue being operated on or the body cavity submitted to the procedure. With contextual information related to the surgical procedure, the surgical system can, for example, improve the way in which it controls the modular devices (for example, a robotic arm and / or robotic surgical instrument) that are connected to him and provide contextual information or suggestions to the surgeon during the course of the surgical procedure.
[00537] [00537] Now with reference to Figure 62, a timeline 5200 represents the situational recognition of a central controller, such as the central surgical controller 106 or 206, for example. Timeline 5200 is an illustrative surgical procedure and the contextual information that the central surgical controller 106, 206 can derive from data received from data sources at each stage in the surgical procedure. Timeline 5200 represents typical steps that would be taken by nurses, surgeons, and other medical personnel during the course of a pulmonary segmentectomy procedure, starting with the setup of the operating room and ending with the transfer of the patient to a post-op recovery room.
[00538] [00538] Situational recognition of a central surgical controller 106, 206 receives data from data sources throughout the course of the surgical procedure, including data generated each time medical personnel use a modular device that is paired with the controller central surgical 106, 206. Central surgical controller 106, 206 can receive this data from paired modular devices and other data sources and continuously derive inferences (that is, contextual information) about the ongoing procedure as new data is received , such as which step of the procedure is being performed at any given time. The situational recognition system of the central surgical controller 106, 206 is, for example, able to record data referring to the procedure to generate reports, verify the steps being taken by medical personnel, provide data or warnings (for example , via a display screen) that may be relevant to the specific step of the procedure, adjust the modular devices based on the context (for example, activate monitors, adjust the field of view of the medical imaging device or change the energy level of a ultrasonic surgical instrument or RF electrosurgical instrument) and take any other action described above.
[00539] [00539] In the first step 5202, in this illustrative procedure, the members of the hospital team retrieve the electronic patient record (PEP) from the hospital's PEP database. Based on patient selection data in the PEP, the central surgical controller 106, 206 determines that the procedure to be performed is a thoracic procedure.
[00540] [00540] In the second step 5204, the team members scan the entry of medical supplies for the procedure. Central surgical controller 106, 206 cross-references the scanned supplies with a list of supplies that are used in various types of procedures and confirms that the supply mix corresponds to a thoracic procedure. Additionally, the central surgical controller
[00541] [00541] In the third step 5206, the medical team scans the patient's bracelet with a scanner that is communicably connected to the central surgical controller 106, 206. The central surgical controller 106, 206 can then confirm the patient's identity based on the scanned data.
[00542] [00542] In the fourth step 5208, the medical team turns on the auxiliary equipment. The auxiliary equipment being used may vary according to the type of surgical procedure and the techniques to be used by the surgeon, but in this illustrative case, they include a smoke evacuator, an insufflator and a medical imaging device. When activated, auxiliary equipment that is a modular device can automatically pair with the central surgical controller 106, 206 which is located within a specific neighborhood of the modular devices as part of its initialization process. The central surgical controller 106, 206 can then derive contextual information about the surgical procedure by detecting the types of modular devices that correspond with the same during this preoperative or initialization phase. In this particular example, the central surgical controller 106, 206 determines that the surgical procedure is a VATS (video-assisted thoracic surgery) procedure based on this specific combination of paired modular devices. Based on the combination of data from the electronic patient record (PEP), the list of medical supplies to be used in the procedure, and the type of modular devices that connect to the central controller, the central surgical controller 106, 206 can, in general, infer the specific procedure that the surgical team will perform. After the central surgical controller 106, 206 recognizes which specific procedure is being performed, the central surgical controller 106, 206 can then retrieve the steps of that process from a memory or from the cloud and then cross over the data which subsequently receives from connected data sources (for example, modular devices and patient monitoring devices) to infer which stage of the surgical procedure the surgical team is performing.
[00543] [00543] In the fifth step 5210, members of the medical team fix the electrocardiogram (ECG) electrodes and other patient monitoring devices on the patient. ECG electrodes and other patient monitoring devices are able to pair with the central surgical controller 106, 206. As central surgical controller 106, 206 begins to receive data from the patient's monitoring devices, the surgical controller central 106, 206 thus confirms that the patient is in the operating room.
[00544] [00544] In the sixth step 5212, medical personnel induce anesthesia in the patient. Central surgical controller 106, 206 can infer that the patient is under anesthesia based on data from modular devices and / or patient monitoring devices, including ECG data, blood pressure data, ventilator data, or combinations thereof, for example. After the completion of the sixth step 5212, the preoperative portion of the lung segmentectomy procedure is completed and the operative portion begins.
[00545] [00545] In the seventh step 5214, there is a collapse of the lung of the patient being operated on (while ventilation is diverted to the contralateral lung). The central surgical controller 106, 206 can infer from the ventilator data that the patient's lung collapsed, for example. The central surgical controller 106, 206 can infer that the operative portion of the procedure started when he could compare the detection of the patient's lung collapse in the expected steps of the procedure (which can be accessed or retrieved earlier) and, thus, determine that the collapse of the lung is the first operative step in this specific procedure.
[00546] [00546] In the eighth step 5216, the medical imaging device (for example, a display device) is inserted and the video from the medical imaging device is started. Central surgical controller 106, 206 receives data from the medical imaging device (i.e., video or image data) through its connection to the medical imaging device. Upon receipt of data from the medical imaging device, the central surgical controller 106, 206 can determine that the portion of the laparoscopic surgical procedure has started. In addition, the central surgical controller 106, 206 can determine that the specific procedure being performed is a segmentectomy, rather than a lobectomy (note that a wedge procedure has already been discarded by the central surgical controller 106, 206 based on the data received in the second step 5204 of the procedure). The data from the medical imaging device 124 (Figure 2) can be used to determine contextual information about the type of procedure being performed in several different ways, including by determining the angle at which the medical imaging device is oriented in relation to the visualization of the patient's anatomy, monitoring the number of medical imaging devices being used (ie, which are activated and paired with the central surgical controller 106, 206) and monitoring the types of devices visualization devices used. For example, a technique for performing a VATS lobectomy places the camera in the lower anterior corner of the patient's chest cavity above the diaphragm, while a technique for performing a VATS segmentectomy places the camera in a position.
[00547] [00547] In the ninth step 5218, the surgical team starts the dissection step of the procedure. Central surgical controller 106, 206 can infer that the surgeon is in the process of dissecting to mobilize the patient's lung because he receives data from the RF or ultrasonic generator that indicate that an energy instrument is being triggered. Central surgical controller 106, 206 can cross-check the received data with the steps retrieved from the surgical procedure to determine that an energy instrument is being triggered at that point in the process (that is, after completing the previously discussed steps of the procedure) corresponds to the dissection stage. In certain cases, the energy instrument may be a power tool mounted on a robotic arm in a robotic surgical system.
[00548] [00548] In the tenth stage 5220, the surgical team proceeds to the stage of connection of the procedure. Central surgical controller 106, 206 can infer that the surgeon is ligating the arteries and veins because he receives data from the surgical stapling and cutting instrument indicating that the instrument is being fired. Similar to the previous step, the central surgical controller 106, 206 can derive this inference by crossing the reception data from the surgical stapling and cutting instrument with the steps recovered in the process. In some cases, the surgical instrument can be a surgical tool mounted on a robotic arm of a robotic surgical system.
[00549] [00549] In the eleventh step 5222, the segmentation portion of the procedure is performed. Central surgical controller 106, 206 can infer that the surgeon is transitioning the parenchyma based on data from the surgical stapling and cutting instrument, including data from its cartridge. The cartridge data can correspond to the size or type of clamp being triggered by the instrument, for example. As different types of staples are used for different types of fabrics, the cartridge data can thus indicate the type of fabric being stapled and / or transected. In this case, the type of clamp that is fired is used for the parenchyma (or other similar types of tissue), which allows the central surgical controller 106, 206 to infer which segmentectomy portion of the procedure is being performed.
[00550] [00550] In the twelfth step 5224, the node dissection step is then performed. The central surgical controller 106, 206 can infer that the surgical team is dissecting the node and performing a leak test based on the data received from the generator that indicates which ultrasonic or RF instrument is being fired.
[00551] [00551] In the thirteenth stage 5226, the patient's anesthesia is reversed. The central surgical controller 106, 206 can infer that the patient is emerging from anesthesia based on ventilator data (that is, the patient's respiratory rate begins to increase), for example.
[00552] [00552] Finally, in the fourteenth step 5228, medical personnel remove the various patient monitoring devices from the patient. The central surgical controller 106, 206 can therefore infer that the patient is being transferred to a recovery room when the central controller loses ECG, blood pressure and other data from patient monitoring devices. between. As can be seen from the description of this illustrative procedure, the central surgical controller 106, 206 can determine or infer when each step of a given surgical procedure is taking place according to the data received from the various data sources that are communicated together to the central surgical controller 106, 206.
[00553] [00553] Situational perception is further described in US Provisional Patent Application Serial No. 62 / 611,341, entitled INTERACTIVE SURGICAL PLATFORM, filed on December 28, 2017, which is hereby incorporated by reference in its entirety. in. In certain cases, the operation of a robotic surgical system, including the various robotic surgical systems described here, for example, can be controlled by the central surgical controller 106, 206 based on its situational perception and / or component feedback. and / or based on information from the cloud 102.

Obviously, different and / or post-developed connection-oriented network communication protocols are also contemplated in the present invention.
[00583] [00583] Unless stated specifically to the contrary, as is evident from the preceding description, it is understood that, throughout the preceding description, discussions that use terms such as "processing", "computation", "calculation", " determination "," display "or similar, refer to the action and processes of a computer, or similar electronic computing device, which manipulates and transforms the data represented in the form of physical (electronic) quantities in records and memories of the computer in other data represented in a similar way in the form of physical quantities in the memories or records of the computer, or in other similar devices for storing, transmitting or displaying information.
[00584] [00584] One or more components in the present invention may be called "configured for", "configurable for", "operable / operational for", "adapted / adaptable for", "capable of", "con- formable / conformed to ", etc. Those skilled in the art will recognize that "configured for" may, in general, include components in an active state and / or components in an inactive state and / or components in a standby state, except when the context determines otherwise .
[00585] [00585] The terms "proximal" and "distal" are used in the present invention with reference to a physician who handles the handle portion of the surgical instrument.

It will also be understood that, for the sake of convenience and clarity, spatial terms such as "vertical", "horizontal", "up" and "down" can be used in the present invention with respect to the drawings. However, surgical instruments can be used in many orientations and positions, and these terms are not intended to be limiting and / or absolute.
[00586] [00586] Persons skilled in the art will recognize that, in general, the terms used here, and especially in the appended claims (for example, bodies of the appended claims) are generally intended as "open" terms (for example, the term "including" should be interpreted as "including, but not limited to", the term "having" should be interpreted as "having, at least", the term "includes" should be interpreted as "includes, but is not limited to ", etc.). It will also be understood by those skilled in the art that, when a specific number of a claim statement entered is intended, that intention will be expressly mentioned in the claim and, in the absence of such mention, no intention will be present. For example, as an aid to understanding, the following appended claims may contain the use of the introductory phrases "at least one" and "one or more" to introduce claim statements. However, the use of such phrases should not be interpreted as implying that the introduction of a claim statement by the indefinite articles "one, ones" or "one, ones" limits any specific claim containing the claim mention. claims that contain only such a mention are introduced, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles, such as "one, ones" or "one, ones" (for example, example, "one, ones" and / or "one, ones" should typically be interpreted as meaning "at least one" or "one or more"); the same goes for the use of defined articles used to introduce claims.
[00587] [00587] Furthermore, even if a specific number of an introduced claim statement is explicitly mentioned, those skilled in the art will recognize that that statement needs to be typically interpreted as meaning at least the number mentioned (for example, the mere mention of "two mentions", without other modifiers, typically means at least two mentions, or two or more mentions). In addition, in cases where a convention is used
[00588] [00588] With respect to the attached claims, those skilled in the art will understand that the operations mentioned in the same can, in general, be performed in any order. In addition, although several operational flow diagrams are presented in one or more sequences, it must be understood that the various operations can be performed in other orders than those shown, or can be performed simultaneously. Examples of these alternative orderings may include overlapping, interleaved, interrupted, reordered, incremental, preparatory, supplementary, simultaneous, inverse or other variant orders, except when the context determines otherwise. In addition, terms such as "responsive to", "related to" or other adjectives participles are not intended in general to exclude these variants, except when the context determines otherwise.
[00589] [00589] It is worth noting that any reference to "one (1) aspect", "one aspect", "an exemplification" or "one (1) exemplification", and the like means that a given resource, structure or characteristic described in connection with the aspect is included in at least one aspect. Thus, the use of expressions such as "in one (1) aspect", "in one aspect", "in an example", "in one (1) example", in several places throughout this specification it does not necessarily refer to the same aspect. In addition, specific resources, structures or characteristics can be combined in any appropriate way in one or more aspects.
[00590] [00590] Any patent application, patent, non-patent publication or other description material mentioned in this descriptive report and / or mentioned in any order data sheet is incorporated by reference, until the point where the materials incorporated are not inconsistent with this. Accordingly, and to the extent necessary, the description as explicitly presented herein replaces any conflicting material incorporated by reference to the present invention. Any material, or portion thereof, considered to be incorporated by reference here, but which conflicts with the definitions, statements, or other description materials existing herein, will be incorporated here only to the extent that it does not there is a conflict between the embedded material and the existing description material.
