    Descriptive Report of the Invention Patent for CLAIM ALIGNMENT AND POSITIONING FEATURES
    INTEGRATED FABRIC FOR SURGICAL STAPLER.
    BACKGROUND [0001] In some procedures, endoscopic surgical instruments may be preferred over traditional open surgical devices, as a smaller incision can reduce recovery time and complications in the postoperative period. Consequently, some endoscopic surgical instruments may be suitable for placing a distal end actuator in a desired surgical site through a trocar cannula. These distal end actuators can engage tissue in a variety of ways to achieve a diagnostic or therapeutic effect (for example, cutter, forceps, cutter, stapler, clip applicator, access device, drug delivery / gene therapy device, and device for application of energy using ultrasound, RF, laser, etc.). Endoscopic surgical instruments can comprise a rod between the end actuator and a cable portion, which is handled by the physician. This stem can allow insertion to a desired depth and rotation around the longitudinal axis of the stem, thus facilitating the positioning of the end actuator on the patient. The positioning of an end actuator can be further facilitated by the inclusion of one or more features or articulation joints, allowing the end actuator to be selectively articulated or otherwise deflected in relation to the longitudinal axis of the stem.
    [0002] Examples of endoscopic surgical instruments include surgical staplers. Some of these staplers work to secure layers of fabric, cut through the layers of fabric attached and guide the staples through the layers of fabric.
    2/35 fabric to substantially seal the cut layers of tissue to each other, close to the cut ends of the tissue layers The merely exemplary surgical staplers are disclosed in US Patent No. 4,805,823, entitled Pocket Configuration for Internal Organ Staplers, granted on February 21, 1989; US Patent No. 5,415,334, entitled Surgical Stapler and Staple Cartridge, issued May 16, 1995; US Patent No. 5,465,895, entitled Surgical Stapler Instrument, issued November 14, 1995; US Patent No. 5,597,107, entitled Surgical Stapler Instrument, issued January 28, 1997; US Patent No. 5,632,432, entitled Surgical Instrument, issued May 27, 1997; US Patent No. 5,673,840, entitled Surgical Instrument, issued October 7, 1997; US Patent No. 5,704,534, entitled Articulation Assembly for Surgical Instruments, issued January 6, 1998; US Patent No. 5,814,055, entitled Surgical Clamping Mechanism, issued September 29, 1998; US Patent No. 6,978,921, entitled Surgical Stapling Instrument Incorporating an EBeam Firing Mechanism, issued December 27, 2005; US Patent No. 7,000,818, entitled Surgical Stapling Instrument Having Separate Distinct Closing and Firing Systems, issued February 21, 2006; US Patent No. 7,143,923, entitled Surgical Stapling Instrument Having a Firing Lockout for an Unclosed Anvil, issued December 5, 2006; US Patent No. 7,303,108, entitled Surgical Stapling Instrument Incorporating a Multi-Stroke Firing Mechanism with a Flexible Rack, issued December 4, 2007; US Patent No. 7,367,485, entitled Su rgical Stapling Instrument Incorporating a Multistroke Firing Mechanism Having a Rotary Transmission, issued May 6, 2008; US Patent No. 7,380,695, entitled Surgical Stapling Instrument Having a Single Lockout Mechanism for Prevention of Firing, issued June 3

    [0003] Although the aforementioned surgical staplers are described as being used in endoscopic procedures, it should be understood that these surgical staplers can also be used in open procedures and / or other non-endoscopic procedures. Just as an example, a surgical stapler can be inserted through a thoracotomy and thus between a patient's ribs to reach one or more organs in a thoracic surgical procedure that does not use a trocar as a conduit for the stapler. These procedures may include using the stapler to cut and close a vessel that leads to a lung. For example, the vessels that lead to an organ can be cut and closed by a stapler before removal of the organ from the chest cavity. Naturally, surgical staplers can be used in many other configurations and procedures.

    [0027] The drawings are in no way intended to be limiting, and it is envisaged that various embodiments of the invention may be carried out in a variety of other ways, including those not necessarily represented in the drawings. The drawings incorporated in the annex, and which form a part of the specification, illustrate various aspects of the present invention and, together with the description, serve to explain the principles of the invention, it is understood, however, that this invention is not limited to the provisions shown. DETAILED DESCRIPTION [0028] The following description of specific examples of the invention should not be used to limit the scope of the present invention. Other examples, characteristics, aspects, modalities and advantages of the invention will become evident to those skilled in the art from the following description, which is by way of illustration, one of the best ways contemplated for carrying out the invention. As will be understood, the invention may have other different and obvious aspects, all without departing from the invention. Consequently, drawings and descriptions should be considered as illustrative and not restrictive in nature.
    L Exemplary surgical stapler [0029] Figures 1 to 7 represent an exemplary surgical stapling and cutting instrument 10 that is sized for insertion, in a non-articulated state, as shown in Figure 1 A, through a trocar cannula at a site surgery on a patient to perform a surgical procedure. Only the title
    7/35
    For example, this trocar can be inserted into a patient's abdomen, between two of the patient's ribs, or elsewhere. In some configurations, instrument 10 is used without a trocar. For example, instrument 10 can be inserted directly through a thoracotomy or other type of incision. The instrument 10 of the present example includes a portion of cable 20 connected to a stem 22. The stem 22 ends distally at a hinge joint 11, which is further coupled with an end actuator 12. It should be understood that terms such as proximal and distal are used in the present invention with reference to a clinical grip cable portion 20 of instrument 10. Thus, end actuator 12 is distal to the most proximal cable portion 20. It will be recognized further, for convenience and clarity , spatial terms such as vertical and horizontal are used in the present invention in connection with the drawings. However, surgical instruments can be used in many orientations and positions, and such terms are not intended to be limiting and absolute.
    [0030] In some versions, rod 22 is constructed in accordance with at least some of the teachings of US Patent Application No. [Attorney Document Number END7181 USNP.O 599180], entitled Surgical Instrument with Multi-Diameter Shaft, deposited on the same date as this application, the description of which is incorporated by reference in this document; Other suitable configurations for the rod 22 will be evident to the person skilled in the art in view of the teachings of the present invention.
    [0031] Once the hinge joint 11 and end actuator 12 are inserted through the passage of a trocar cannula, the hinge joint 11 can be remotely articulated, as shown in the dashed line in Figure 1, by a pivot control 13 so that end actuator 12
    8/35 can be deflected from the longitudinal axis (LA) of the rod 22 at a desired angle α. The end actuator 12 can thus reach the back of an organ or approach the tissue from a desired angle or for other purposes. In some versions, the pivot joint 11 allows deflection of the end actuator 12 along a single plane. In some other versions, the pivot joint 11 allows deflection of the end actuator along more than one plane. The hinge joint 11 and the hinge control 13 can be configured in accordance with the teachings of any of the numerous references that are cited in the present invention. Alternatively, the hinge joint 11 and / or the hinge control 13 can have any other suitable configuration. As an example only, the articulation control 13 can instead be configured as a handle that rotates about an axis that is perpendicular to the longitudinal axis (LA) of the stem 22.
    [0032] In some versions, the hinge joint 11 and / or the hinge control 13 are / are constructed and operable (s) in accordance with at least some of the teachings of US Patent Application No. Attorney Document END7174USNP.0 599176], entitled Surgical Instrument End Effector Articulation Drive with Pinion and Opposing Racks, filed on the same date as this application, the description of which is incorporated by reference in this document; The articulation joint 11 can also be constructed and operable in accordance with at least some of the teachings of US Patent Application No. [Attorney Document Number 110515 END7181USNP.0599180], the disclosure of which is hereby incorporated by reference. Various other suitable shapes which the hinge joint 11 and the hinge control 13 can assume will become apparent to elements skilled in the art in view
    9/35 of the teachings of the present invention.
    [0033] The end actuator 12 of the present example includes a lower jaw 16 and a pivoting anvil 18. In some versions, the lower jaw 16 is constructed in accordance with at least some of the teachings of US Patent Application No. [No. Attorney Document END7182USNP.0599227], entitled Installation Features for Surgical Instrument End Effector Cartridge, filed on the same date as this application, the description of which is incorporated into this document as a reference; Several alternative exemplifying features, configurations and operabilities that can be incorporated into anvil 18 will be described in greater detail below. In addition, anvil 18 can be constructed in accordance with at least some of the teachings of US Patent Application No. [Attorney Document Number END7180USNP.0599175], entitled Staple Forming Features for Surgical Stapling Instrument, filed on the same date as this application, the description of which is incorporated by reference in this document; Other suitable shapes that the lower claw 16 and the anvil 18 can take will become apparent to elements skilled in the art in view of the teachings of the present invention.
    [0034] The handle portion 20 includes a pistol grip 24 and a closing trigger 26. The closing trigger26 is pivoting relative to the pistol grip 24 to cause the anvil 18 to clamp or close in the direction of the lower jaw 16 of the end actuator 12. Such anvil closure 18 is provided through a closing tube 32 and a closing ring 33, which both travel longitudinally with respect to the cable portion 20 in response to the rotation of the closing trigger 26 with respect to the pistol grip 24. The closing tube 32 extends along the length of the rod 22; and the closing ring 33 is in position
    10/35 distal to the articulation joint 11. The articulation joint 11 is operable to communicate / transmit the longitudinal movement of the closing tube 32 to the closing ring 33.
    [0035] The cable portion 20 also includes a firing trigger 28. An elongated member 136 shown in Figure 11 extends longitudinally through the rod 22 and communicates a longitudinal firing motion from the cable portion 20 to a bar firing 14 in response to firing trigger 28. This distal translation of firing bar 14 causes stapling and cutting of the tissue attached to end actuator 12, as will be described in greater detail below. Thereafter, triggers 26, 28 can be released to release tissue from the end actuator
    12.
    [0036] Figures 3 to 6 show the end actuator 12 employing an electronic beam form of the firing bar 14 to perform numerous functions. It should be understood that an electronic beam form is merely an illustrative example. The firing bar 14 can have any other suitable shape, including, but not limited to, shapes that are non-electronic beam. As can best be seen in Figures 4A to 4B, the firing bar 14 includes a top pin transversely oriented 38, a cap of the firing bar 44, an intermediate pin oriented transversely 46 and a cutting edge shown distally 48. The pin upper 38 is positioned and translatable within an anvil slit 42 of the anvil 18. The firing bar cover 44 engages a lower surface of the lower jaw 16 causing the firing bar 14 to extend through the jaw slit bottom 45 (shown in Figure 4B) which is formed through the lower claw 16. The intermediate pin 46 slidably engages a top surface of the lower claw 16, cooperating with the trigger bar cover 44. Thus, the bar
    11/35 of firing 14 spaces the end actuator 12 positively during firing.
    [0037] Some forms of non-electronic beam firing bar 14 may not have the upper pin 38, intermediate pin 46 and / or the cover of the firing bar 44. Some such versions of instrument 10 may simply rely on the ring closure 33 or some other means of pivoting the anvil 18 to a closed position and keeping the anvil 18 in the closed position while the firing bar 14 advances to the distal position. By way of example only, the firing bar 14 and / or the associated locking features can be constructed and operable in accordance with at least some of the teachings of US Patent Application No. [Attorney Document Number END7182USNP.0599227], entitled Lockout Feature for Movable Cutting Member of Surgical Instrument, filed on the same date as this application, the description of which is incorporated by reference in this document; Other suitable forms which the firing bar 14 can take will be evident to those of ordinary skill in the art in view of the teachings in this document.
    [0038] Figure 3 shows the firing bar 14 of the present example positioned proximally and the anvil 18 pivoted to an open position, allowing an unconsumed staple cartridge 37 to be removably installed in a channel of the lower claw
    16. As can best be seen in Figures 5 to 6, the staple cartridge 37 of this example includes a cartridge body 70, which has an upper support 72 and is coupled to a lower cartridge tray 74. As can best be seen in In Figure 3, a vertical slot 49 is formed through part of the staple cartridge 37. As is also best seen in Figure 3, three rows of staple opening 51 are formed through the upper support
    12/35 on one side of vertical slot 49, with another set of three rows of staple openings 51 being formed through the upper support 72 on the other side of vertical slot 49. Of course, any other suitable number of rows of staples ( for example, two rows, four rows, any other number) can be provided. Again with reference to Figures 4A to 6, a triangular body slider 41 and a plurality of clip drivers 43 are captured between the cartridge body 70 and tray 74, with the triangular body slider 41 being located proximal to the staple drivers 43. The triangular body slider 41 is movable longitudinally inside the staple cartridge 37, while the staple actuators 43 are vertically movable inside the staple cartridge 37. The staples 47 are also positioned inside the cartridge body 70, above the corresponding clamp actuators 43. In particular, each clamp 47 is guided vertically inside the cartridge body 70 by a clamp actuator 43 to guide the clamp 47 out through an associated clamp opening 51. As you can see better in Figures 4A to 4B and 6, the triangular body slider 41 has inclined meat surfaces that force staple guards 43 upwards as the triangular body slider 41 is guided distally through the staple cartridge 37.
    [0039] Various components, configurations and exemplifying operations that can be incorporated in the staple cartridge 37 will be described in greater detail below. The staple cartridge 37 may also be constructed and operable in accordance with at least some of the teachings of US Patent Application No. [Attorney Document Number END7182USNP.0599227], the disclosure of which is incorporated herein by reference. Other suitable forms which the staple cartridge 37 can take will be avoided.
    13/35 teeth to those of ordinary skill in the technique in view of the teachings in this document.
    [0040] With the end actuator 12 closed, as shown in Figures 4A to 4B, by advancing in the distal position of the closing tube 32 and the closing ring 33, the firing bar 14 is then advanced in engagement with the anvil 18, causing the upper pin 38 to enter the longitudinal anvil slot 42. A drive block 80 shown in Figure 5 is located at the distal end of the firing bar 14 and is configured to engage the triangular body slider 41 so that the triangular body slider 41 is pushed in the distal position by the propeller block 80 as the firing bar 14 is advanced in the distal position through the clamp cartridge 37. During such firing, the cutting edge 48 of the firing bar 14 enters in the vertical slot 49 of the staple cartridge 37, separating the fabric fixed between the staple cartridge 37 and the anvil 18. As shown in Figures 4A to 4B, the intermediate pin 46 and the drive block 80, in conjunction However, they activate the staple cartridge 37 when entering a vertical slot 49 inside the staple cartridge 37, which leads the wedge-shaped slide 41 to the upward contact of meat with the staple actuators 43, which, in turn, push the clamps 47 through the clamp openings 51 and into the forming contact with the clamp forming cavities 53 (shown in Figure 3) on the inner surface of the anvil 18. Figure 4B represents the firing bar 14 fully displaced in the distal position after completing the cutting and stapling of the fabric. It should be understood that the staple-forming cavities 53 are intentionally omitted from the view in Figures 4A to 4B; but the staple-forming cavities 53 are shown in Figure 3. Furthermore, it should be understood that the anvil 18 is intentionally omitted from the view in Figure 5.
    14/35 [0041] Figure 7 shows the end actuator 12 having been actuated through a single pass through the fabric 90. As shown, the cutting edge 48 (omitted in Figure 7) cuts through the fabric 90, while the actuators of staples 43 lead three alternating rows of staples 47 through the fabric 90 on each side of the cutting line produced by the cutting edge 48. The staples 47 are all oriented substantially parallel to the cutting line in this example, although it should be understood that the staples 47 can be positioned in any suitable orientations. In the present example, end actuator 12 is removed from the trocar after the first drive is completed, the consumed staple cartridge 37 is replaced with a new staple cartridge and end actuator 12 is then reinserted through the trocar to reach the stapling location for additional cutting and stapling. This process can be repeated until the desired number of cuts and staples 47 has been provided. It may be necessary to close the anvil 18 to facilitate insertion and removal through the trocar, and it may be necessary to open the anvil 18 to facilitate the replacement of the staple cartridge 37.
    [0042] It should be understood that the cutting edge 48 can separate the fabric substantially at the same time as the clamps 47 that are being guided through the fabric during each actuation actuation. In the present example, the cutting edge 48 slows slightly behind the conduction of the clips 47, so that a clip 47 is guided through the fabric just before the cutting edge 48 passes through the same region of the fabric, although it is to be understood that this order can be reversed or that the cutting edge 48 can be directly synchronized with the adjacent staples. Although Figure 7 shows the end actuator 12 being actuated in two layers 92, 94 of fabric 90, it must be understood
    15/35 that the end actuator 12 can be actuated through a single layer of fabric 90 or more than two layers 92, 94 of fabric. It should also be understood that the formation and positioning of staples 47 adjacent to the cutting line produced by the cutting edge 48 can substantially seal the tissue at the cutting line, thereby reducing or preventing bleeding and / or leakage from other body fluids in the cut-line. Furthermore, although Figure 7 shows the end actuator 12 being driven in two flat planar layers, substantially flat 92, 94 of fabric, it should be understood that the end actuator 12 can also be acted through a tubular structure, as a blood vessel, a section of the gastrointestinal tract, etc. Figure 7 should therefore not be seen as demonstrating any limitation on the intended uses for the end actuator 12. Various suitable configurations and procedures in which instrument 10 can used will be apparent to those skilled in the art in view of the teachings of the present invention.
    [0043] It should be understood that instrument 10 can be configured and is operable in accordance with any other teachings of US Patent No. 4,805,823; US Patent No. 5,415,334; Pay US No. 5,465,895; US Patent No. 5,597,107; US Patent No. 5,632,432; US Patent No. 5,673,840; US Patent No. 5,704,534; Patent and US No. 5,814,055; US Patent No. 6,978,921; US Patent No. 7,000,818; US Patent No. 7,143,923; US Patent No. 7,303,108; Patent and US No. 7,367,485; US Patent No. 7,380,695; US Patent No. 7,380,696; US Patent No. 7,404,508; US Patent No. 7,434,715; Patent and US No. 7,721,930; US Patent Publications No. 2010/026419 3; and / or 2012/0239012. As noted above, the descriptions of each of these patents and publications are hereby incorporated by reference. Additional exemplary modifications that can
    16/35 to be provided for instrument 10 will be described in more detail below. Various suitable ways in which the teachings below can be incorporated into instrument 10 will be apparent to those skilled in the art. Similarly, various suitable forms in which the teachings below can be combined with various teachings of the patents / publications cited in the present invention will be apparent to those skilled in the art. It should also be understood that the teachings below are not limited to the instrument 10 or the devices taught in the patents cited in the present invention. The teachings below can be readily applied to several other types of instruments, including instruments that would not be classified as surgical staplers. Various other suitable devices and scenarios in which the teachings below can be applied will be apparent to those skilled in the art in view of the teachings of the present invention.
    IL Exemplary motor drive features [0044] In the present example, instrument 10 provides motorized control of the firing bar 14. Figures 8 to 11 show exemplifying components that can be used to provide motorized control of the firing bar 14. In In particular, Figure 8 shows an exemplary control circuit 100 that can be used to power an electric motor 102 with electricity from a battery pack 104 (also shown in Figures 1 to 2). Electric motor 102 is operable to move the firing bar 14 longitudinally, as will be described in greater detail below. It should be understood that the entire control circuit 100, including motor 102 and battery 104, can be housed within the cable portion 20. Figure 8 shows the trigger trigger 28 as an open switch, although it should be understood that this switch is closed when the trigger 28 is activated. Circuit 100 in this example
    17/35 also includes a safety switch 106 which must be closed to complete circuit 100, although it should be understood that safety key 106 is purely optional. The security key 106 can be closed by pressing a separate button, sliding element, or other feature on the cable portion 20.
    [0045] Circuit 100 of the present example also includes a locking switch 108, which is configured to be closed by default, but is automatically opened in response to a locking condition. As an example only, a locking condition may include one or more of the following: the absence of a cartridge 37 in the lower jaw 16, the presence of a consumed cartridge (for example, previously fired) 37 in the lower jaw 16, an anvil insufficiently closed 18, a determination that the instrument 10 has been fired many times, and / or any other suitable conditions. Various sensors, algorithms and other features that can be used to detect locking conditions will be evident to those skilled in the art in view of the teachings in this document. Similarly, other suitable forms of locking conditions will be apparent to those skilled in the art in view of the teachings in this document. It is to be understood that circuit 100 is open and therefore motor 102 is inoperable when locking key 108 is open. A locking indicator 110 (for example, an LED (light-emitting diode), etc.) is operable to provide a visual indication of the status of locking key 108. For example, locking key 108, the indicator locking device 110 and associated components / features can be configured in accordance with at least some of the teachings of US Patent No. 7,644,848, entitled Electronic Lockouts and Surgical Instrument Including Same, granted on January 12, 2010, the description of which is here incorporated by way of
    18/35 reference.
    [0046] Once the firing bar 14 reaches a more distal position, for example, at the end of a cutting stroke, an end-of-stroke switch 112 is automatically changed to a closed position, reversing the polarity of the applied voltage that of motor 102. This reverses the direction of rotation of motor 102, it being understood that the operator will have released the trigger trigger 28 at this stage of the operation. In this operational state, the current flows through a reverse direction indicator 114 (e.g., LED, etc.) to provide a visual indication to the operator that the motor rotation 102 has been reversed. Various suitable ways in which the end-of-stroke switch 112 can be automatically changed to a closed position when the firing bar 14 reaches a more distal position will be apparent to those skilled in the art in view of the teachings of the present invention. Similarly, various suitable forms that the reverse direction indicator 114 can take will become apparent to elements skilled in the art in view of the teachings of the present invention.
    [0047] The cable portion 20 of the present example also includes a manual return switch 116, which is also shown on circuit 100. Manual return switch 116 is configured to act as a help feature, which allows the operator to start quickly the retraction of the firing bar 14 proximally during a firing stroke. In other words, the manual return switch 116 can be triggered manually when the firing bar 14 has only been partially distally advanced. The manual return switch 116 can provide functionality similar to that of the end-of-stroke switch 112, inverting the polarity of the voltage applied to motor 102 to invert, thus, the direction of rotation of motor 102. Again, this inversion can be visually indicated through the indicator
    19/35 reverse direction 114.
    [0048] In some versions, one or more of the keys 28, 106, 108, 112, 116 are in the form of micro keys. Other suitable forms will be apparent to those skilled in the art in view of the teachings of the present invention. In addition, or instead of the preceding, at least part of circuit 100 may be configured in accordance with at least some of the teachings of US Patent No. 8,210,411, entitled Motor-Driven Surgical Instrument, issued on July 3, 2012, whose description is incorporated by reference in this document;
    [0049] Figures 9 to 11 show exemplary mechanical components that can be used to provide a motorized firing bar translation 14. In particular, Figure 9 shows the motor 102 housed in the pistol grip 24 of the cable portion 20. it is understood that battery 104 (shown in Figures 1 to 2) can also be located on pistol grip 24 (for example, below engine 102) and / or elsewhere on the cable portion 20. Engine 102 has a drive rod 120 which is coupled with a gear set 122. Gear set 122 has an outer casing not shown and can be operated to drive an upper gear 126, which is shown in Figure 10. Upper gear 126 meshes with a pinion 128, which is rotatably supported by a pin 129 fixed on the cable portion 20. Therefore, it must be understood that the activation of the motor 102, finally, rotates the pinion 128 within the cable portion 20.
    [0050] As also shown in Figures 9 to 10, a converter rack 130 includes teeth 132 that mesh with pinion 128, so that rack 130 travels longitudinally when pinion 128 rotates. As shown in Figure 11, rack 130 is coupled with an elongate member 136 that extends through
    20/35 through rod 22 and includes a distal end 138, which mates with the proximal end of the firing bar 14. As shown in Figure 11, rack 130 is coupled with an elongated member 136 extending through rod 22 and includes a distal end 138, which mates with the proximal end of the firing bar
    14. Therefore, it should be understood that the activation of motor 102, finally, moves the firing bar 14 inside the end actuator 12. In particular, the motor 102 can drive the firing bar 14 in a distal position to cut the fabric 90 and guide the clamps 47 to the fabric 90. A key actuation arm 134 extends laterally from the rack 130, and is positioned to engage the end-of-stroke key 112 when the firing bar 14 reaches a position more distal (for example, after fabric 90 has been cut and staples 47 have been guided to fabric 90). As noted above, this end-wrench coupling 112 automatically reverses motor 102 to return firing bar 14 from the most distal position to the proximal position, allowing the anvil 18 to be pivoted away from the lower claw 16 to release the fabric 90.
    [0051] The use of the term pivot (and similar terms with pivot as a base) should not be understood in a way that necessarily requires pivoting movement around a fixed axis. In some versions, anvil 18 pivots around an axis that is defined by a pin (or similar feature), which slides along an elongated groove or groove as anvil 18 moves towards the lower claw 16. In these versions, the articulation axis moves along the path defined by the slot or groove while the anvil 18 pivots simultaneously around that axis. In addition, or alternatively, the pivot axis can slide along the slot / groove first, with the anvil 18, then pivot around the pivot axis, after the pivot axis has slid a certain distance along gives
    21/35 slot / channel. It should be understood that such sliding / translating pivotal movement is encompassed within terms such as pivot, pivot, pivotal, pivot, pivot and similar. Naturally, some versions can provide the pivotal movement of the anvil 18 on an axis that remains fixed and does not translate into a slot or channel, etc.
    [0052] In addition, or instead of the aforementioned, the operable features for activating the firing bar 14 can be configured in accordance with at least some of the teachings of US Patent Publication No. 2012/0239012, the description of which is incorporated herein document by reference; and / or in accordance with at least some of the teachings of US Patent Publication No. 201 2/0239012, the description of which is incorporated herein by reference. Other components, features and configurations suitable for providing motorization of the firing bar 14 will be evident to those skilled in the art in view of the teachings of the present invention. It should also be understood that some other versions can provide manual activation of the firing bar 14, so that an engine can be omitted. As an example only, the firing bar 14 can be activated according to at least some of the teachings of any other patent / publication reference cited here.
    Ill · Exemplary end actuator with stabilizing features [0053] In some cases, it may be desirable to provide a mechanism to ensure that the anvil 18 has been correctly secured against cartridge 37 and at an appropriate height from cartridge 37 before firing staples 47 for fabric 90. For example, in the case where the anvil 18 and the cartridge 37 attach against the fabric, which can be very thick in one area and thinner in another,
    22/35 it is desirable to align the anvil 18 against the cartridge 37, even with uneven fabric fixed between them. After fixing the tissue, it may also be desirable to avoid lateral rolling and / or lateral pivoting deflection of the anvil 18 in relation to the cartridge 37.
    [0054] Figure 12 shows an exemplary end actuator 212 operable for use with an instrument, such as instrument 10 shown in Figure 1. For example, end actuator 212 can be used in place of end actuator 12. It will be appreciated that the actuator 212 can be integrally formed with the articulation mechanism 11 or it can be formed separately and removably connected to the articulation mechanism 11. Other suitable variations will be evident to those skilled in the art in view of the teachings of the present invention. The end actuator 212 comprises an anvil 218 and a lower jaw 216. The lower jaw 216 can be operated to secure the staple cartridge 237. In general, the anvil 218 attaches against the cartridge 237 to secure the fabrics together. Thereafter, the clips inside the cartridge 237 can be fired into the tissue and anchored to the tissue, as a result of the clips being flexed against the anvil 218. With respect to tissue attachment and triggering of the clips, the end actuator 212 is substantially similar to end actuator 12 in Figure 1. As anvil 218 comes into contact with cartridge 237, the features that will be discussed below can be used to laterally stabilize anvil 218. As a result, staples (such as staples 47 ) can be fired from the cartridge 237 through the fabric and against the anvil 218 without the anvil 218 turning laterally in relation to the cartridge 237.
    [0055] Figure 13 shows an enlarged view of end actuator 212. Cartridge 237 comprises a plurality of protrusions extending upwards laterally 250. Co
    23/35 m can be seen in Figure 14, the side protrusions 250 comprise two protrusions spaced laterally 250. The protrusions 250 are spaced apart so that when the anvil 218 closes on the cartridge 237, the anvil 218 does not swing laterally in relation to the 237 cartridge. In the illustrated version, the protrusions 250 have a shallow end, in a rounded shape, although it should be understood that any suitable shape for the protrusions 250 can be used, as would be evident to an element versed in the art taking into account the teachings presented here. For example, protrusions 250 may have a pointed or high plateau shape. In some versions, protrusions 250 can be positioned along the length of cartridge 237.
    [0056] Figure 15 represents a diagrammatic end view of end actuator 212 that illustrates a bearing angle Θ 213 of anvil 218 with respect to a longitudinal axis 260 that extends through the center of end actuator 212. It will be appreciated that the bearing angle Θ 213 represents a positive or negative side bearing from the 0 ° angle, in the case where the fabric 90 causes the anvil 218 to roll against the cartridge 237. The side protrusions 250 are operable to provide two points of contact between the anvil 218 and the cartridge 237, so that the rolling angle Θ 213 of the anvil 218 remains approximately close to 0 o when the anvil 218 comes into contact with the lateral protuberances 250. It should be understood that , due to the fixation of the fabric between the anvil 218 and the cartridge 237, the rolling angle Θ 213 can deviate from 0 °, but only slightly, due to the provided double contact points by protrusions 250. In other words, as anvil 218 closes on cartridge 237, anvil 218 may roll laterally during the closing movement on cartridge 237; however, contact
    24/35 between the anvil 218 and the protrusions 250 is operable to correct any lateral bearing of the anvil 218. As a result, the clamps form cavities 253 (seen in Figure 16) that align with the openings 251 (seen in Figure 17) before of the staple firing. In addition, protrusions 250 are consistently established where the preload of anvil 218 will be applied against the upper support of cartridge 237. Although the exemplary version shows protrusions 250 located in cartridge 237, it will be understood that, in addition or alternatively, protrusions 250 can be positioned on anvil 218. Other suitable positions for protrusions 250 for lateral stabilization of anvil 218 will be evident to an element skilled in the art in view of the teachings of the present invention. Figure 13 also shows anvil 218 having a protrusion 219 operable to engage protrusions 250, thereby promoting additional contact between cartridge 237 and anvil 218. Protrusion 219 is shaped like a generally flat surface, although other shapes suitable can be used, as would be apparent to the person skilled in the art in view of the teachings of the present invention. Lump 219 can also be seen in Figure 16.
    [0057] It will also be appreciated that, in some cases, as the anvil 218 closes against the cartridge 237, it may be desirable to avoid or correct the lateral pivot deflection of the anvil 218 in relation to the cartridge 237.
    [0058] Figure 16 shows a bottom view of anvil 218 showing an engagement groove 270. The engagement groove 270 is shaped like an elongated semi-spherical groove inside the anvil 218, although it is understood that the engagement groove 270 may have any suitable shape to receive a 272 protrusion (shown in Figure 17), which will be discussed in more detail below. Groove 270, at
    25/35 illustrated version, comprises a linear curved portion 271 and spherical curved portions 273, which flank the linear curved portion to form groove 270. Groove 270 of the exemplary version is centered laterally along anvil 218, although others may be used suitable positions for groove 270. In the illustrated version, hitch groove 270 is positioned so that hitch groove 270 and protrusions 250 form a generally triangular shape when anvil 218 is closed against cartridge 237. Naturally, this configuration it is only an illustrative example, and these characteristics can be subject to several suitable alternative provisions. The anvil 218 is shaped to taper laterally towards the engagement groove 270 in the present example, although any suitable shape for the anvil 218 can be used, as would be evident for an element skilled in the art in view of the teachings of the present invention.
    [0059] Figure 17 shows the cartridge 237 of the end actuator 212 with a protrusion 272. It will be appreciated that when the anvil 218 closes against the cartridge 237, the protrusion 272 fits inside the coupling groove 270. In particular, protrusion 272 can first contact the spherical curved portion 273, and slide into the linear curved portion 271 as the anvil 218 is pressed towards the cartridge 237. It will be appreciated that the engagement groove 270 is dimensioned larger than the protrusion 272. As a result, protrusion 272 does not necessarily need to be perfectly aligned with the hitch groove 270 for hitch groove 270 to capture the protrusion 272. Cartridge 237 of the example version tapers laterally and vertically towards protrusion 272 to form a narrowed tip, although it should be understood that any suitable shape for the 237 cartridge can be used, as would be technical expert
    26/35 taking into account the teachings presented here.
    [0060] The protrusion 272 is operable to capture a portion of the coupling groove 270, such as the spherical curved portion 273, where, after that, the curved contour of the coupling groove 270 allows the protuberance 272 to slide to a more central portion of the coupling groove 270, like the linear curved portion 271, thus providing a fit between the protrusion 272 and the engaging groove 270. Since the protuberance 272 and the engaging groove 270 are completely engaged with each other, it will be appreciated that the anvil 218 cannot deflect laterally in relation to the cartridge 237. For example, in the example version, the width of the coupling groove 270 complements the diameter of the protrusion 272, thus preventing the deflection of the anvil 218 and promoting the alignment of the anvil 218 and the cartridge 237. However, the length of the hitch groove 270 is greater than the diameter of the hump 272, thus promoting the hitch of the hump 272 and the hitch groove 270 and, in addition thus, promoting the sliding of the protrusion 272 towards the linear curved portion 271 of the coupling groove 270. It should also be understood that, if anvil 218 is deflected laterally in a pivoting way during closing, the coupling groove 270 and the protuberance 272 cooperate to orient anvil 218 for alignment.
    [0061] Figure 18 shows longitudinal axis 260 that extends through the center of end actuator 212. A deflection angle β 262 represents the amount of deflection to the left or right of the longitudinal axis 260 that anvil 218 can experience in some scenarios during use. For example, deflection of anvil 218 could occur in the event that thick or particularly dense tissue is positioned between the anvil 218 and the cartridge 237, as the anvil 218 fixes against the cartridge 237 or when the density and / or thickness of the fabric in the area between the anvil
    27/35
    218 and the lower jaw 216 varies along the width of the anvil 218 and the lower jaw 216. Naturally, as discussed above, it will be appreciated that, by engaging the engagement groove 270 with the protrusion 272, the anvil 218 resists deflection, thus maintaining the deflection angle β 262 at about 0 ° in relation to the longitudinal axis 260. It will be understood that, in some circumstances, slight deflection could occur, but in general, the protrusion 272 and the coupling groove 270 help to maintain the deflection angle β 262 at or close to 0 ° in relation to the longitudinal axis 260.
    [0062] Furthermore, as can be seen in Figure 16, the anvil 218 has an anvil tip 220, where the anvil tip 220 has an inclined, folded shape, angled towards the cartridge 237. It will be appreciated that the folded shape of the anvil tip 220 complements the shape of the cartridge 237, so that the anvil 218 more resists deflection in relation to the cartridge 237. Although the exemplary version describes the anvil tip 220 having a curved shape, it should be understood that the anvil tip anvil 220 must necessarily have a curved shape, and the coupling groove 270 and the protrusion 272 can be used in situations where the anvil tip 220 is oriented in a linear manner with respect to the rest of the anvil 218. Indeed, the groove hitch 270 and protrusion 272 can also be used in conjunction with cartridges, 237 which can be linear, instead of having an angled tip, as seen, for example, in Figure 12.
    [0063] Figure 19 represents an alternative exemplary version of an end actuator 312. It will be appreciated that end actuator 312 can be used interchangeably with, or in place of end actuator 12, 212, as seen in Figures 1 and 12. End actuator 312 comprises anvil 318 and lower jaw 316. Lower jaw 316 is in communication
    28/35 with a cartridge 337 operable to hold a plurality of clips in a substantially similar manner with respect to the lower jaw 16 and the cartridge 37 shown in Figure 3. The anvil tip 320 is bent to generally complement the shape of the cartridge 237, although it is to be understood that the anvil tip 320 may have other suitable shapes.
    [0064] The end actuator 312 further comprises an anvil aligning member positioned distally 370 and a lateral stabilizing member 372. It will be appreciated that alignment member 370 is operable to define the spacing between anvil 318 and cartridge 337 in the distal end of end actuator 312. In addition, a side stabilizing member 372 is operable to laterally stabilize anvil 318 against cartridge 337, which will be described in more detail below.
    [0065] The alignment member 370 of the present example has a wedge shape with a triangular cross section. It will be understood that the triangular wedge shape of alignment member 370 is configured to complement the outline of anvil 318 and cartridge 337. For example, in some cases, it may be desirable to maintain a specific distance between anvil 318 and cartridge 337 with based on the type and / or thickness of the fabric to be placed between the anvil 318 and the cartridge 337. The alignment member 370 can thus be positioned between a portion of the anvil 318 and the cartridge 337 to prevent the anvil 318 from closing against cartridge 337 beyond that desired by the user. In addition, alignment member 370 not only prevents further closure of anvil 318 against cartridge 337, but alignment member 370 allows anvil 318 to maintain a specific distance from cartridge 337. In addition, an alignment member 370 fills the space between the anvil 318 and the cartridge 337, so that the
    29/35 such of the anvil 318 and the cartridge 337, with the alignment member 370 placed between them, forms a blunt atraumatic end that can be used to urge the end actuator 312 through the fabric without any inadvertent capture of the anvil 318 or 337 on the fabric. In the exemplary version, anvil 318 and cartridge 337 have a planar profile, where anvil 318 and cartridge 337 meet alignment member 370. However, it will be appreciated that anvil 318 and cartridge 337 can have other suitable shapes, such as it will be evident to an element skilled in the art in view of the teachings of the present invention. Thus, an alignment member 370 can also be of any suitable shape to complement anvil 318 and cartridge 337. It will be appreciated that, in some versions, alignment member 370 may be removable in relation to anvil 318 or cartridge 337, or it can be integrally formed with anvil 318 or cartridge 337. In still other exemplary versions, it will be appreciated that alignment member 370 can be divided such that one portion is connected to anvil 318, where another portion is connected to the cartridge 337. In some cases, end actuator 312 may be provided with a plurality of modular alignment members 370 having different shapes and sizes, so that the user could, for example, use a shape for alignment member 370 in one type of fabric and another shape or size of the alignment member 370 in another type of fabric.
    [0066] The side stabilizing members 372 can also be seen in Figure 19, and in addition, a front cross-sectional view of the side stabilizing members 372 can be seen in Figure 20. The side stabilizing members 372 comprise parts of operable material to provide lateral contact between the anvil 318 and the cartridge 337. As can be seen in Figure 20, the members
    30/35 side stabilization brushes 372 include two contact members with a space provided between them. It will be appreciated that by placing lateral stabilization members 372 on opposite side sides of anvil 318 and cartridge 337, when anvil 318 closes in cartridge 337 during use, anvil 318 comes into contact with lateral stabilization members 372. When in contact with the lateral stabilizing members 372, the anvil 318 becomes laterally stabilized, such that the anvil 318 does not swing left or right in relation to the cartridge 337 In particular, the lateral stabilization member 372 provides a surface of contact along the lateral stabilizing member 372 for engaging the anvil 318. As a result, it will be observed that as the anvil 318 closes on the cartridge 337, although the anvil 318 may roll laterally due to the grip against the tissue of the various thicknesses or densities, the anvil 318 straightens laterally as the anvil 318 closes against the side stabilizing members 372. The members of lateral stabilization 372 therefore work similarly to the protrusions 250 in Figure 13. In some exemplary versions, the lateral stabilizing members 372 can be positioned on the anvil 318 instead of the cartridge 337. In still other exemplary versions, the limbs lateral stabilization plates 372 can be placed on both the anvil 318 and the cartridge 337. Other suitable versions of the lateral stabilization members 372 will be apparent to the person skilled in the art in view of the teachings of the present invention. It will be appreciated that, in some versions, the side stabilizing members 372 and / or aligning members 370 can be used in conjunction with end actuator 212 shown in Figure 13, thereby providing more added stabilization.
