    [0028] For clarity of description, the terms "proximal" and "distal" are defined herein in relation to a robotic surgical actuator comprising a proximal housing that has an interface that mechanically and electrically couples with a surgical instrument that has an effector. distal surgical end. The term "proximal" refers to the position of an element closer to the robotic surgical actuator housing and the term "distal" refers to the position of an element closer to the surgical end effector of the surgical instrument and further away from the housing. I. Overview of the Exemplifying Robotic Surgical System
    [0029] Figure 1 illustrates an exemplary robotic surgical system 10. The system 10 comprises at least one controller 14 and at least one arm carriage 18. The arm carriage 18 is mechanically and/or electronically coupled to one or more robotic manipulators or arms 20. Each of the robotic arms 20 comprises one or more surgical instruments 22 for performing various surgical tasks on a patient 24. The operation of the arm carriage 18, including the arms 20 and instruments 22, can be controlled by a physician 12 from a controller 14. In some embodiments, a second controller 14', operated by a second physician 12', may also command the operation of the arm carriage 18, in conjunction with the first physician 12. For example, each of the doctors, 12 and 12', can control different arms 20 of the carriage or, in some cases, full control of the carriage of arm 18 can be passed between doctors 12 and 12'. In some examples, additional arm carriages (not shown) may be used on patient 24. These additional arm carriages may be controlled by one or more of the controllers 14 and 14'.
    [0030] The arm carriages 18 and controllers 14 and 14', may be in communication with each other via a communication link 16, which may be any suitable type of wired or wireless communication link, carrying any type signal (e.g. electrical, optical, infrared, etc.), according to any suitable communication protocol. Communication links 16 may be a physical link or may be a logical link using one or more physical links. When the link is a logical link, the physical link type may be a data link, uplink, downlink, fiber optic link, point-to-point link, for example, as is well known in the computer networking art for refer to the communication facilities that connect the nodes of the network.
    [0031] Figure 2 shows an example controller 30 that can serve as a controller 14 of system 10. In this example, controller 30 generally includes a user input unit 32 that has precise user input elements (not shown) that are picked up by the surgeon and manipulated in space while the surgeon observes the surgical procedure via a screen image 34. User input elements of user input unit 32 may include manual input devices that move with multiple degrees of freedom; and this includes an actuatable handle for intuitively actuatable tools (eg to close stuck saws, apply an electrical potential to an electrode, etc.). The controller 30 of the present example also includes an array of pedals 38 that provide additional control of arms 20 and instruments 22 to the surgeon. Screen 34 may show views of one or more endoscopes showing the surgical site on the patient and/or any other suitable view. In addition, a feedback gauge 36 can be viewed through the screen 34, and provide the surgeon with a visual indication of the amount of force being applied to the instrument component 22 (e.g., a cutting element or clamping element, etc.). Other sensor arrangements may be employed to provide controller 30 with an indication as to whether a staple cartridge has been loaded into instrument end actuator 22, whether instrument anvil 22 has been moved to a closed position prior to firing, and/or other instrument operating condition 22.
    [0032] Figure 3 shows an exemplary robotic arm car 40 that can serve as arm car 18 of system 10. In this example, arm car 40 is operable to activate a plurality of surgical instruments 50. While three instruments 50 are shown in this example, it should be understood that arm carriage 40 may be operable to hold any suitable number of surgical instruments 50. Surgical tools 50 are all supported by a series of manually pivotable links, generically called adjustment joints 44, and a robotic manipulator 46. These structures are illustrated in the present invention with protective coatings that extend over much of the robotic link. These protective coatings may be optional and may be limited to any size or entirely eliminated in some embodiments to minimize the inertia that is encountered by the servomechanisms used to manipulate such devices, to limit the volume of moving components, in order to avoid collisions and to limit the total weight of the car 40.
    [0033] Each robotic manipulator 46 terminates in an instrument platform 70, which is pivoting, swiveling, and otherwise movable to the manipulator 46. Each platform includes an instrument dock 72 that is slidable along the pair of rails 74 to the position furthest from the instrument 50. Such sliding is motorized in the present example. Each instrument dock 72 includes mechanical and electrical interfaces that mate with an interface assembly 52 of instrument 50. By way of example only, dock 72 may include four rotary outputs that mate with the complementary rotary outputs of the interface assembly 52. Such rotary driving features can drive various functionality in the instrument 50, as described in various references cited in the present invention and/or as described in more detail below. Electrical interfaces may establish communication through physical contact, inductive coupling, and/or otherwise; otherwise, it may be operable to supply electrical power to one or more features on the instrument 50, provide commands and/or communication data to the instrument 50, and/or provide commands and/or communication data from the instrument 50. Various Suitable ways in which a dock instrument 72 can communicate mechanically and electrically with an interface assembly 52 of an instrument 50 will become apparent to those skilled in the art based on the teachings of the present invention. It is also to be understood that the instrument 50 may include one or more cables that couple with a separate power source and/or a control unit, to provide electrical communication and/or commands/data to/from the instrument 50.
    [0034] The arm carriage 40 of the present example also includes a base 48 which is movable (eg, by a single attendant) to selectively position the arm carriage 40 with respect to the patient. The carriage 40 may generally be of adequate dimensions to transport the carriage 40 between operating rooms. Cart 40 can be configured to pass through standard operating room doors and into standard hospital elevators. In some versions, an automated instrument reloading system (not shown) can be positioned on or flush with the working envelope 60 of the arm carriage 40, to selectively reload components (e.g. staple cartridges etc.) of the instruments 50.
    [0035] In addition to the foregoing, it should be understood that one or more aspects of system 10 may be constructed in accordance with at least some of the teachings of U.S. Patent No. 5,792,135; U.S. Patent No. 5,817,084; U.S. Patent No. 5,878,193; U.S. Patent No. 6,231,565; U.S. Patent No. 6,783,524; U.S. Patent No. 6,364,888; U.S. Patent No. 7,524,320; U.S. Patent No. 7,691,098; U.S. Patent No. 7,806,891; U.S. Patent No. 7,824,401 and/or in U.S. Patent Publication Serial No. 2013/0012957. The disclosure of each of the aforementioned U.S. patents and the U.S. Patent Publications are incorporated herein by reference. Other features and operability that may be incorporated into system 10 will be apparent to those skilled in the art in view of the teachings of the present invention. J. . Exemplifying ultrasonic surgical instrument with articulation feature
    [0036] Figures 4 to 18 show an exemplifying ultrasonic surgical instrument 100 that can be used as at least instrument 50 in the system (10). At least part of the instrument 100 may be constructed and operable in accordance with at least some of the teachings of U.S. Patent No. 5,322,055; U.S. Patent No. 5,873,873; U.S. Patent No. 5,980,510; U.S. Patent No. 6,325,811; U.S. Patent No. 6,783,524; U.S. Publication No. 2006/0079874; U.S. Publication No. 2007/0191713; U.S. Publication No. 2007/0282333; U.S. Publication No. 2008/0200940; U.S. Publication No. 2010/0069940; U.S. Publication No. 2011/0015660; U.S. Publication No. 13/538,588; U.S. Publication No. 13/657,553 and/or in U.S. Patent Publication Serial No. 61/410,603. The disclosures of each of the foregoing patents, publications and applications are incorporated herein by reference. As described therein and as will be described in more detail below, instrument 100 is operable to cut tissue and seal or weld tissue (e.g., a blood vessel, etc.) substantially simultaneously. In other words, instrument 100 operates similarly to a type of stapler, except that instrument 100 provides tissue welding by applying ultrasonic vibration energy, rather than providing staple lines to join tissue. This same ultrasonic vibration energy also separates tissue similar to tissue separation by a converter knife member. It should be understood that the 100 instrument may have many structural and functional similarities to HARMONIC ACE® Ultrasonic Scissors, HARMONIC WAVE® Ultrasonic Scissors, HARMONIC FOCUS® Ultrasonic Scissors and/or HARMONIC SYNERGY® Ultrasonic Blades. In addition, instrument 100 may have many structural and functional similarities to devices taught in any of the other references cited and incorporated by reference into the present invention.
    [0037] To the extent that there is some degree of overlap between the teachings of the references cited in the present invention, HARMONIC ACE® ultrasonic scissors, HARMONIC WAVE® ultrasonic scissors, HARMONIC FOCUS® ultrasonic scissors and/or HARMONIC SYNERGY ultrasonic blades ® , and in the following teachings relating to instrument 100, any description contained in the present invention is not intended to be understood as prior art. On the contrary, the scope of several of the teachings of the present invention is broader than the scope of the teachings of the references cited in the present invention and HARMONIC ACE® ultrasonic scissors, HARMONIC WAVE® ultrasonic scissors, HARMONIC FOCUS® ultrasonic scissors and blades. HARMONIC SYNERGY® ultrasonic devices.
    [0038] The instrument 100 of the present example includes an interface assembly 200, a rod assembly 110, a pivot section 130 and an end actuator 150. The interface assembly 200 is configured to mate with the arm carriage dock 72 40 and is further operable to drive the hinge section 130 and end effector 150, as will be described in more detail below. As will be described in more detail below, instrument 100 is operable to articulate end effector 150 to provide the desired position relative to tissue (e.g., a large blood vessel, etc.) and then apply vibration energy. ultrasound to the fabric with an end effector 150 to cut and seal the fabric.
    [0039] As will be described in more detail below, the instrument 100 of the present example includes an ultrasonic transducer 120, which is operable to convert electrical energy to ultrasonic vibrations. In some instances, transducer 120 receives power directly through dock 72. In other instances, transducer 120 includes a separate cable 302 that directly couples transducer 120 to generator 300. Generator 300 may include a power source and a module for control that is configured to provide a power profile to transducer assembly 120 that is especially suited for generating ultrasonic vibrations through transducer 120. By way of example only, generator 300 may comprise a GEN 300 sold by Ethicon Endo-Surgery , Inc. of Cincinnati, Ohio, USA. Additionally or alternatively, generator 300 may be constructed in accordance with at least some of the teachings of US Patent Application No. 2011/0087212 entitled "Ultrasonic Device for Cutting and Coagulating", published April 14, 2011, the description of which is here incorporated by way of reference. Still other suitable forms that generator 300 may take, as well as various features and functionality that generator 300 may provide, will be apparent to those skilled in the art from the teachings of the present invention. It should also be understood that at least part of the functionality of generator 300 may be incorporated directly into interface assembly 200. By way of example only, interface assembly 200 may include an integral battery or other integral power source, as well as as any circuit required for the condition of battery power or other integral power source to drive the 120 ultrasonic transducer. K. Acoustics and Exemplifying End Effector Transmission
    [0040] As can best be seen in Figures 6 to 8, the end effector 150 of the present example comprises a gripper arm 152 and an ultrasonic blade 160. The gripper arm 152 includes a gripper block 154 which is secured to the underside of the claw arm 152, facing the blade 160. The claw arm 152 is pivotally secured to the tongue projecting distally 133 from a first portion of the ribbed body 132, which forms part of the hinged section 130, as will be described with more details below. The gripper arm 152 is operable to selectively pivot toward and away from the blade 160 to selectively grip the fabric between the gripper arm 152 and the blade 160. A pair of arms 156 extend transversely to a gripper arm 152 and are secured to a pin 170 which extends laterally between arms 156. A rod 174 is secured to pin 170. Rod 174 extends distally from closure tube 176 and is individually secured to tube closure system 176.
    [0041] A conductive ring 178 is attached to the proximal end of the closure tube 176. In particular, as best seen in Figure 13, the proximal end of the closure tube 176 includes a transverse opening 177 which is configured to align with an opening 179 of lead ring 178. These openings 177 and 179 are configured to receive a pressure screw (not shown) or other feature that secures lead ring 178 to closure tube 176. Lead ring 178 is slidably arranged coaxially with outer casing 112, while closure tube 176 is coaxially slidably disposed to the interior of outer casing 112. However, outer casing 112 includes a longitudinally extending slot 114 that is configured to receive the pressure screw that secures the outer casing 112. conductive ring 178 to the closing tube 176. In this way, the slot 114 allows the conduction ring 178 and the closing tube 176 to translate together with respect to the outer casing 112. The positioning of the pressure screw in the slot 114 also provides for rotation of the closure tube 176 and the driving ring 178 about the longitudinal axis of the outer casing 112 when the outer casing 112 is rotated around the longitudinal axis, as described in more detail below.
    [0042] As described in more detail below, the interface assembly 200 includes features that are operable to drive the lead ring 178, closure tube 176 and stem 174 longitudinally with respect to outer casing 112 and with respect to pivot section 130 It should be understood that this translation of the lead ring 178, closing tube 176 and rod 174 will provide the articulation of the gripper arm 152 towards the blade 160 (when the ring 178, the tube 176 and the rod 174 are translated in a proximal); or in the opposite direction of blade 160 (when ring 178, tube 176, and rod 174 are translated distally). The rod 174 is flexible enough to bend with the pivot section 130. However, the rod 174 has sufficient traction and compressive force to drive the gripper arm 152 when the rod 174 is translated, regardless of whether the pivot section 130 is in a straight or bent.
    [0043] As can best be seen in Figures 7 to 8, the spring bundle 172 is captured between the jaw arm 152 and the jaw block 172 and is in contiguity with the distal face of the tongue 133. The spring bundle 172 is resiliently biased to drive a gripper arm 152 away from blade 160 to the open position shown in Figures 4, 6 and 8. Spring bundle 172 thereby further displaces tube 176 and rod 174 distally. Of course, like other components described in the present invention, the spring bundle 172 can be omitted if desired. Furthermore, the gripper arm 152 and gripper block 154 can be omitted if desired.
    [0044] The blade 160 of the present example is operable to vibrate ultrasonic frequencies to effectively cut through the tissue and seal it, particularly when the tissue is trapped between the jaw block 154 and the blade 160. The jaw 160 is positioned at the end distal of an acoustic transmission. This acoustic transmission includes an array of transducers 120, a rigid acoustic waveguide 180 and a flexible acoustic waveguide 166. As best seen in Figures 5 and 12 to 17, the array of transducers 120 includes an array of piezoelectric disks. 122 located proximally to a horn 182 of a rigid acoustic waveguide 180. Piezoelectric discs 122 are positioned coaxially along the proximally extended pin 181, which is a unitary feature of proximally located acoustic waveguide 180. to the horn 182. A solid end nut 124 is secured to the pin 181 thereby securing the piezoelectric discs 122 to the rigid acoustic waveguide 180. As noted above, the piezoelectric discs 122 are operable to convert electrical energy into ultrasonic vibrations, which are then transmitted along the rigid acoustic waveguide 180 to the blade 160. The rigid acoustic waveguide 180 is best seen in the Figures. 13 and 17 through 18. As shown in Figure 13, the rigid acoustic waveguide 180 includes a transverse aperture 186 that complements a transverse aperture 118 formed in the outer housing 118. A pin 184 is disposed in the apertures 118 and 186 to engage the housing. 112 with the rigid acoustic waveguide 180. This coupling provides rotation of the acoustic waveguide 180 (and the rest of the acoustic transmission) about the longitudinal axis of the outer housing 112 when the external housing 112 is rotated about the axis longitudinally, as will be described in more detail below. In the present example, aperture 186 is located in a position corresponding to a node associated with resonant ultrasonic vibrations communicated through rigid acoustic waveguide 180.
    [0045] The rigid acoustic waveguide 180 ends distally in a coupling 188 which can be seen in Figures 8 to 11 and 13. The coupling 188 is secured to the coupling 168 by a double threaded pin 169. The coupling 168 is located at the proximal end. of the flexible acoustic waveguide 166. As best seen in Figures 7 to 11, the flexible acoustic waveguide 166 includes a distal flange 136, a proximal flange 138 and a narrower section 164 located between the flanges 138. At present For example, flanges 136 and 138 are located in a position corresponding to a node associated with resonant ultrasonic vibrations communicated through flexible acoustic waveguide 166. Narrow section 164 is configured to allow flexible acoustic waveguide 166 to flex without harm. significantly improves the ability of the flexible acoustic waveguide 166 to transmit ultrasonic vibrations. By way of example only, the narrow section 164 may be configured in accordance with one or more of the teachings of U.S. Patent Application No. 13/538,588 and/or U.S. Patent Publication No. 13/657,553, the disclosures of which are incorporated herein. present invention by way of reference. It should be understood that waveguides 166 and 180 may be configured to amplify magnetic vibrations transmitted through waveguides 166 and 180. In addition, waveguides 166 and 180 may further include features to control the gain of vibrations. along the waveguide 166 and 180, and/or means for tuning the waveguide 166 and 180 to the resonant frequency of the system.
    [0046] In the present example, the distal end of the ultrasonic blade 160 is located in a position that corresponds to an antinode associated with resonant ultrasonic vibrations, communicated through the waveguide 166, to tune the acoustic set to the preferred resonant frequency fo when the set acoustic is not loaded with fabric. When the transducer assembly 120 is energized, the distal end of the ultrasonic blade 160 is configured to move longitudinally in the range, for example, approximately 10 to 500 microns peak to peak, and in some cases, in the range of about 20 to 500 microns. about 200 microns at a predetermined vibrating frequency of, for example, 55.5 kHz. When the transducer assembly 120 of the present example is activated, these mechanical oscillations are transmitted through the waveguides 180 and 166 to reach the blade 160, thereby promoting the oscillation of the blade 160 at the resonant ultrasonic frequency. Thus, when tissue is trapped between blade 160 and gripper arm 154, the ultrasonic oscillation of blade 160 can simultaneously disrupt tissue and denature proteins in adjacent tissue cells, thereby providing a coagulant effect with relatively thermal propagation. small. In some versions, an electrical current may also be supplied through blade 160 and gripper arm 154 to cauterize tissue as well. While some configurations for an acoustic transmission assembly and transducer assembly 120 have been described, other configurations suitable for an acoustic transmission assembly and transducer assembly 120 will yet become apparent to those skilled in the art, based on the teachings of the present invention. Similarly, other suitable configurations for end actuator 150 will become apparent to those skilled in the art based on the teachings of the present invention. L. Articulation Section and Exemplifying Rod Assembly
    [0047] The stem assembly 110 of the present example extends distally from the interface assembly 200. The hinge section 130 is located at the distal end of the stem assembly 110, with the end effector 150 being located distally to the hinge section. 130. Stem assembly 110 includes an outer housing 112 that contains conduction features and the acoustic transmission features described above that couples interface assembly 200 with hinge section 130 and end effector 150. Stem assembly 110 is rotatable about the longitudinal axis defined by housing 112, with respect to interface assembly 200. Such rotation may provide rotation of end effector 150, pivot section 130 and rod assembly 110 unitarily. Of course, rotating features can simply be omitted if desired.
    [0048] The pivot section 130 is operable to selectively position the end effector 150 at various lateral deflection angles with respect to the longitudinal axis defined by the housing 112. The pivot section 130 can take a variety of forms. By way of example only, hinge section 130 may be configured in accordance with one or more of the teachings of U.S. Patent Application No. 2012/0078247, the disclosure of which is incorporated herein by reference. As another merely illustrative example, hinge section 130 may be configured in accordance with one or more of the teachings of U.S. Patent Application No. 13/538,588 and/or U.S. Patent Publication No. 13/657,553, the disclosures of which are incorporated into the present invention by way of reference. Various other suitable shapes that the hinge section 130 may take will be apparent to those skilled in the art in view of the teachings of the present invention. It should also be understood that some versions of the instrument 10 may not have the articulation section 130.
    [0049] As can best be seen in Figures 6 to 11, the hinge section 130 of the present example comprises a first ribbed body part 132 and a second ribbed body portion 134, with a pair of hinge bands 140 and 142 extending through channels defined at the interfaces between the ribbed body portions 132 and 134. The ribbed body portions 132 and 134 are positioned substantially longitudinally between the flanges 136 and 138 of the flexible acoustic waveguide 166. The distal ends of the hinge bands 140 and 142 are unitarily secured to the distal flange 136. The hinge bands 140 and 142 also pass through the proximal flange 138, yet the hinge bands 140 and 142 are slidable relative to the proximal flange 138.
    [0050] The proximal end of the hinge band 140 is secured to the first driving ring 250, while the proximal end of the hinge band 142 is secured to the second driving ring 251. As can best be seen in Figures 13 and 17, the first ring conductor 250 includes an annular flange 252 and an inwardly projecting anchor feature 254, while a second lead ring 251 also includes an annular flange 253 and an inwardly projecting anchor feature 255. The proximal end of the band The pivot bracket 140 is fixedly secured to the anchor feature 254, while the proximal end of the pivot band 142 is fixedly attached to the anchor feature 255. The drive rings 250 and 251 are slidably disposed around the proximal end of the outer casing. 112. Outer housing 112 includes a pair of longitudinally extending slots 116 and 117 that are configured to receive anchor features 254 and 255 respectively. slots 116 and 117 allow the drive rings 250 and 251 to translate with respect to the outer casing 112. The positioning of the anchor features 254 and 255 and slots 116 and 117 also provide rotation of the rings 250 and 251 and pivot bands 140 and 11. 142 about the longitudinal axis of the outer shell 112 when the outer shell 112 is rotated about the longitudinal axis, as described in more detail below.
    [0051] As will be described in more detail below, the interface assembly 200 is operable to selectively pull a hinge band 140 and 142 proximally by proximally pulling a driving ring 250; while simultaneously allowing the other hinge band 140 and 142 and the driving ring 251 to translate distally. It should be understood that as the linkage band 140 and 142 is pulled proximally, this will cause the linkage section 130 to flex, thereby causing the end effector 150 to deflect in the opposite direction of the longitudinal axis of the linkage assembly. rod 110 at a specific angle. In particular, the end actuator 150 will pivot to either direction of the proximally retracted pivot band 140 and 142. During such articulation, the other hinge band 140 and 142 will be pulled distally by the flange 136. The ribbed body portions 132 and 134 and the narrow section 164 are flexible enough to accommodate the end effector articulation 150 described above. . Exemplifying Robot Arm Interface Set
    [0052] Figures 5 and 14 to 18 show the interface set 200 of the present example in more detail. As shown, the interface assembly 200 comprises a base 202 and a housing 204. It should be noted that the housing 204 is only shown in Figure 4 and is omitted from Figures 5 and 14 to 18 for clarity. The housing 204 comprises a housing that simply surrounds the driving components. In some versions, housing 204 also includes an electronic circuit board, integrated circuit, and/or other feature that is configured to identify instrument 100.
    [0053] Base 202 is configured to engage dock 72 of robotic arm carriage 40. While not shown, it should be understood that base 202 may also include one or more electrical contacts and/or other operable features to establish electrical communication with add-on features of dock 72. Rod support structure 206 extends upward from base 202 and provides support for rod assembly 110 (while still allowing rod assembly 110 to pivot). By way of example only, the rod support structure 206 may include a conveyor, bearings, and/or other features that facilitate rotation of the rod assembly 110 relative to the support structure 206. As shown in Figure 5, the base 202 additionally includes three drive disks 220, 240, and 260 that are rotatable with respect to base 202. Each disk 220, 240, and 260 includes a respective pair of unit pins 222, 242, and 262 that mate with complementary recesses (not shown). on the dock drive elements 72. In some versions, one pin 222, 242 and 262 of each pair is closer to the axis of rotation of the corresponding disk 220, 240 and 260 to ensure proper angular orientation of the disk 220, 240 and 260 with respect to the corresponding dock driving element 72.
    [0054] As can best be seen in Figures 14 to 16, a leading rod 224, 244 and 264 extends unitarily upward from each disk 220, 240 and 260. As will be described in more detail below, disks 220, 240 and 260 are independently operable to provide independent rotation of rod assembly 110, flexure of hinge section 130, and translation of closure tube 176, through independent rotation of lead rods 224, 244, and 264. Base 202 also includes a 280 idle disk, which simply does not spin or drive any components. A pair of pivot pins 282 and 284 extend unitarily upward from disc 280.
    [0055] As can best be seen in Figures 14 to 16, a first worm gear 226 is fixedly attached to the driving rod 224, so that the rotation of the corresponding disk 220 provides a rotation of the first worm gear 226. The first worm gear 226 meets second helical gear 230, which is unitarily secured to a bushing 232. Bushing 232 is unitarily secured to outer housing 112. In this way, rotation of first helical gear 226 provides rotation of rod assembly 110. It will be understood that rotation of the worm gear 226 about the first axis is converted into rotation of the second worm gear 230 about the second axis, which is orthogonal to the first axis. A clockwise rotation of the second helical gear 230 (viewed from top to bottom) results in clockwise rotation of the shank assembly 110 (viewed from the distal end of the shank assembly 110 towards the proximal end of the shank assembly 110), depending on the thread orientation of the worm gear 226 and 230. A counterclockwise rotation of the second worm gear 132 (viewed from top to bottom) results in a counterclockwise rotation of the rod assembly 110 (viewed from the distal end of the rod assembly 110 towards the proximal end of rod assembly 110), depending on the thread orientation of the worm gear 226 and 230. It should therefore be understood that the rod assembly 110 may be activated by the rotating driving rod 224. Other suitable ways in which the stem assembly 110 may be rotated will be apparent to those skilled in the art in view of the teachings of the present invention.
    [0056] As can best be seen in Figures 14 to 16, a pair of cylindrical cams 246 and 248 are securely attached to the driving rod 244, so that the rotation of the corresponding disk 240 provides a rotation of the cams 246 and 248. Cams 246 and 248 are both mounted midway on drive rod 244 so that the longitudinal axes of cams 246 and 248 are offset from the longitudinal axis of drive rod 244. In addition, cams 246 and 248 are offset. in an opposite manner, so that cams 246 and 248 guard laterally to driving rod 244 in opposite directions. Cams 246 and 248 are positioned to drive pivot arms 286 and 288. Pivot arm 286 is pivotally coupled with pivot pin 282, while pivot pin 288 is pivotally coupled with pivot pin 284. The first ring The lead ring 250 passes through an opening 287 formed by the first lead arm 286, while the second lead ring 251 passes through an opening 289 formed by the second lead arm 288. Each flange 252 and 253 has an outside diameter that is larger than the inner diameter of the corresponding opening 287 and 289. Flanges 252 and 253 thus restrict distal movement of rings 250 and 251 with respect to respective driving arms 286 and 288.
    [0057] As the driving rod 244 is rotated, one of the cams 246 and 248 will proximally pull the corresponding arm 286 and 288, depending on the positioning of these components and the angular positioning of the cams 246 and 248 at the time of rotation. In some cases, cam 246 will drive arm 288 proximally, such that arm 288 pivots counterclockwise (viewed from above) around pin 284. Arm 288 will rest on flange 253 during pivoting, thereby pulling ring 251 and pivot band 142 proximally. This proximal movement of the hinge band 142 will cause the hinge section 130 to bend, with the end effector 150 being deflected towards the band 142. This hinge section band 130 will pull the hinge band 140 distally, which , in turn, will pull the ring 250 and its flange 252 distally. Distal movement of flange 252 will drive arm 286 such that arm 286 pivots counterclockwise (viewed from top to bottom) about pin 282. Cam 248 will be oriented to allow such distal articulation of the arm. 286. As the driving rod 244 continues to rotate (or if the rotating rod 244 is rotated in the opposite direction), the push and pull described above will eventually be reversed. In other words, cam 248 can drive arm 286 proximally while cam 246 allows arm 288 to pivot distally during articulation of hinge section 130 to provide deflection of end effector 150 toward track 140. , it being understood that the rod assembly 130 can be activated by the pivoting driving rod 244. Other suitable ways in which the pivot section 130 can be activated will be apparent to those skilled in the art in view of the teachings of the present invention.
    [0058] As can best be seen in Figures 14 to 16, a cylindrical cam 266 is fixedly attached to the driving rod 264, so that the rotation of the corresponding disk 260 provides a rotation of the first cylindrical cam 266. The cam 266 is mounted in the middle of the driving rod 264, so that the longitudinal axis of the cam 266 is offset from the longitudinal axis of the driving rod 264. The cam 266 is arranged in an oblong opening 272 formed by a support 270, which is translatable in with respect to base 202. Support 270 includes a laterally extending tip 274. Tip 274 is disposed in an annular recess 278 of lead ring 178 which is secured to closure tube 176, as noted above. The configuration of the cam 266 and the configuration of the recess 272 provide a relationship so that the bracket 270 translates longitudinally in response to the rotation of the driving rod 264 and the cam 266. This translation of the bracket 270 provides translation of the closing tube 176 by because of the engagement between the nose 274 and the driving ring 178, and the engagement between the driving ring 178 and the closing tube 176. It should be understood, therefore, that the gripper arm 152 can be selectively driven in the opposite direction. or toward blade 160 by rotating guide rod 264. Other suitable ways in which gripper arm 152 may be activated will be apparent to those skilled in the art in view of the teachings of the present invention. D. Exemplifying Operation
    [0059] In an exemplary use, the arm carriage 40 is used to insert the end effector 150 into a patient via a trocar. The hinge section 130 is substantially linear, and the gripper arm 152 is pivotable toward the blade 160 when the end effector 150 and a stem portion 110 are inserted through the trocar. Drive rod 224 can be rotated through drive means in the dock 72 that are coupled with a mating disc 220 to position an end effector 150 at a desired angular orientation relative to the tissue. Drive rod 244 can then be rotated via dock drive features 72 which are coupled with corresponding disc 240 to pivot or flex pivot section 130 or rod assembly 110 to position end effector 150 in a desired position and orientation in relation to an anatomical structure within the patient. Drive rod 264 can be rotated through dock drive features 72 which are coupled with a corresponding disc 260 to pivot gripper arm 152 in the opposite direction of blade 160, and thus effectively open end effector 150.
    [0060] The tissue of the anatomical structure is then captured between the jaw block 154 and the blade 160 by the rotating driving rod 264 to advance the closing tube 176 distally, upon activation of the driving features in the dock 72 that are coupled with the corresponding disc 260. In some cases, this involves attaching two layers of tissue forming a part of a natural lumen defining the anatomical structure (eg, blood vessels, parts of the gastrointestinal tract, part of the reproductive system, etc.) in a patient. ; therefore, it should be understood that the instrument 100 can be used in a variety of tissue types and anatomical locations. With the tissue trapped between the gripper block 154 and the blade 160, the transducer (120 is driven to deliver ultrasonic vibration to the blade 160. This simultaneously severs the tissue and denatures the proteins in the cells of adjacent tissues, thereby providing a clotting effect. with relatively little thermal spread.
    [0061] The operations of the stem assembly 110, joint section 130 and end effector 150 described above can be repeated as many times as desired, at various locations on the patient. When the operator wishes to retract the end effector 150 from the patient, the driving rod 244 can be rotated through the conductive features in the dock 72 which are coupled with the corresponding disc 240 to strengthen the pivot section 130. The driving rod 264 can be be rotated through dock drive features 72 which are coupled with a corresponding disc 260 to pivot the gripper arm 152 towards the blade 160 and thus effectively close the end effector 150. The arm carriage 40 is then , used to withdraw the patient's terminal effector 150 and trocar. Other suitable ways in which instrument 100 may be operable and operated will be apparent to those skilled in the art in view of the teachings of the present invention. N.I. Other Components
