Description

Background Art

[0001] In some surgical procedures such as gastrointestinal anastomosis, it may be desirable to clamp one or more tissue layers, cut through the clamped layers, and simultaneously drive the nail through the layers to substantially seal the cut layers together near the cut ends of the tissue layers. A type of such instrument that can be used in such surgery is a linear surgical stapler, also referred to as a "linear cutter". A linear surgical stapler generally includes a first half (referred to as a "bin half" or "reload half") and a second half (referred to as an "anvil half"), the first half having a distal jaw configured to support a staple cartridge (or "reload"), and the second half having a distal jaw supporting an anvil surface with a staple forming feature structure. The stapler also includes a movable clamping lever, which is configured to releasably clamp these stapler halves together. These stapler halves are configured to releasably couple together and pivot relative to each other to clamp the tissue between the two distal jaws when the clamping lever is closed. The firing assembly of stapler is configured to be manually actuated to cut the clamped layer and drive nail to pass the tissue on either side of cutting line simultaneously. After stapler is fired, clamping lever can be opened and stapler half part separates to release the tissue of cutting off and stitching.

[0002] While various surgical stapling instruments and associated components have been made and used, it is believed that no one prior to the inventor has made or used the invention described in the appended claims. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] I. Exemplary Linear Surgical Stapler

[0029] A. Overview of Linear Surgical Staplers

[0030] Figure 1 to Figure 2 An exemplary linear surgical stapler (10) (also referred to as a "linear cutter") suitable for a variety of cutting and suturing procedures (such as gastrointestinal anastomosis procedures) is shown. The linear surgical stapler (10) includes a cartridge half (12) (also referred to as a "reloading half") and an anvil half (14), which are configured to be releasably coupled together to clamp tissue therebetween for simultaneous cutting and suturing of the clamped tissue. The linear surgical stapler (10) can be further constructed according to the teachings of the following patent application: U.S. patent application No. 18 / 316,635, entitled "Linear Surgical Stapler," filed on May 12, 2023, the disclosure of which is incorporated herein by reference.

[0031] The cartridge half (12) includes a first elongated member in the form of an elongated cartridge channel (16) having a proximal cartridge frame portion (18) and a distal jaw portion (20). The proximal cartridge frame portion (18) slidably holds the firing assembly (110) and includes a pair of laterally opposed upright side flanges (22). Each side flange (22) includes a distal slot (24) disposed at its distal end and a tapered proximal recess (26) disposed at its proximal end. An outwardly projecting rigid rib (28) extends longitudinally between the distal slot (24) and the proximal recess (26) of each side flange (22) and is configured to provide enhanced rigidity to the side flange (22). An outwardly flared upper section (30) defines an upper edge of the proximal portion of each side flange (22) and is configured to facilitate the cartridge half (12) to receive the anvil half (14). Each side flange (22) also includes an elongated firing slot (32) extending longitudinally along the underside of the side flange (22) between the proximal notch (26) and the distal slot (24). The elongated firing slot (32) is configured to guide the firing assembly (110) between a proximal position and a distal position. Figure 8 Firing assembly (110) is described in greater detail.

[0032] The distal jaw portion (20) of the cartridge channel (16) is configured to releasably receive (or "reload") a staple cartridge (140). Figure 4 As shown, the staple cartridge (140) includes a cartridge body (142) having an upper side defining a first suturing surface in the form of a platform (156) having a plurality of staple openings (166) for accommodating a plurality of staples (not shown) and corresponding staple drivers (not shown).

[0033] The bin half (12) further includes a clamping member (also referred to as a "clamping arm" or "latch lever") in the form of a clamping lever (40) pivotably coupled to the bin channel (16) using a clamping lever pivot pin (42) disposed generally aligned with the distal slot (24) of the bin channel side flange (22). The clamping lever (40) includes an elongated lever arm (44) having a free proximal end (46) and a distal end pivotably coupled to a lower portion of the bin channel (16) using the pivot pin (42). A pair of opposed jaws (48) extend distally from the distal end of the lever arm (44) beside the bin channel side flange (22). Each jaw (48) includes a curved slot (50) having a closed proximal end and an open distal end configured to receive a latch pin (68) of anvil half-section (14), as described below.

[0034] The clamping lever (40) is operable to pivot relative to the cartridge channel (16) between an open position and a closed position, wherein the proximal end (46) of the lever arm (44) is spaced apart from the cartridge channel frame portion (18) (as described below). 9A to 9C In the closed position, the proximal end (46) faces the bin channel frame portion (18) (as described below). Fig.9D Actuation of the clamping lever (40) from the open position to the closed position serves to capture the opposite side ends of the latch pin (68) within the clamping lever jaw slot (50) and thereby clamp the anvil half (14) against the cartridge half (12), as described below in conjunction with FIG. 9C to FIG. 9D As shown and described. In this regard, the curvature of each jaw slot (50) defines a corresponding upper cam surface and a lower cam surface, which are configured to engage the corresponding side ends of the latch pin (68) and pull it toward the bin channel (16) when the clamping lever (40) is pivotally closed. A resilient member shown in the form of a leaf spring (52) biases the lever arm (44) toward the open position. Therefore, when the clamping lever (40) is initially advanced from the closed position toward the open position, the leaf spring (52) promotes the clamping lever jaws (48) to disengage from the anvil half latch pin (68).

[0035] like Figure 2 As best shown, the clamping lever (40) further includes a latch member (54) disposed at the proximal end (46) of the lever arm (44). The clamping lever latch member (54) is configured to resiliently and releasably engage the proximal end of the bin channel frame portion (18), and thereby releasably retain the clamping lever (40) in a closed position, for example, when the stapler (10) is fired. The clamping lever latch member (54) may also be constructed in accordance with the teachings of U.S. Patent No. 11,278,285, entitled “Clamping Assembly for Linear Surgical Stapler,” issued on March 22, 2022, the disclosure of which is incorporated herein by reference.

[0036] The anvil half (14) of the linear surgical stapler (10) includes a second elongated member in the form of an elongated anvil channel (60), the elongated anvil channel having a proximal frame portion (62) and a distal jaw portion (64). The proximal frame portion (62) includes a pair of transversely opposite upright side flanges (66), which are configured to be received between the chamber channel side flanges (22) when the anvil half (14) is connected to the chamber half (12). A distal latch projection in the form of a latch pin (68) extends transversely through the distal end of the anvil channel side flange (66), and a proximal pivot projection in the form of a proximal pin (70) extends transversely through the proximal end of the anvil channel side flange (66). The anvil half pins (68, 70) are configured to facilitate the connection of the anvil half (14) with the chamber half (12), as described below.

[0037] like Figure 2 and Figure 3As shown, the distal jaw portion (64) of the anvil half (14) supports an anvil plate (72), which defines a second suturing surface in the form of an anvil surface having a plurality of staple forming recesses (74), which are configured to deform the legs of the staples ejected from the staple cartridge (140) when the stapler (10) is fired. The staple forming recesses (74) of this example can be formed via an embossing process and are configured to enable each staple in the staple cartridge (140) to form a three-dimensional shape, wherein the legs of each formed staple are laterally offset from each other to provide a non-planar shape for the formed staples, for example, as disclosed in U.S. Patent No. 11,229,433, entitled “Linear Surgical Stapler”, published on January 25, 2022, the disclosure of which is incorporated herein by reference. The anvil channel (60), anvil plate (72) and staple forming pockets (74) may be formed in one or more of the ways disclosed in the following patents: U.S. Patent No. 11,229,433; U.S. Patent No. 11,045,193, entitled "Anvil Assembly for Linear Surgical Stapler" issued on June 29, 2021; and / or U.S. Publication No. 2022 / 0142641, entitled "System and Method for Forming Pockets in Anvil of Surgical Stapler" issued on May 12, 2022, the disclosures of which are incorporated herein by reference. For example, the distal jaw portion (64) of the anvil half (14) may be preformed with a certain curvature along its length, which accommodates the deflection of the distal jaw portion (64) and the anvil plate (72) when the stapler halves (12, 14) are clamped together by the clamping lever (40). The distal jaw portion (64) of the anvil half (14) further supports a tapered distal tip member (76). In some versions, the distal tip member (76) can be selectively extended relative to the distal jaw portion (64) in accordance with the teachings of U.S. Patent No. 11,033,266, entitled "Decoupling Mechanism for Linear Surgical Stapler," issued on June 15, 2021, the disclosure of which is incorporated herein by reference.

[0038] like Figure 2As shown, the linear surgical stapler (10) also includes a pair of covers (56, 78), which cover the selected portion of the stapler (10) and enhance the operator's effective grip and manipulation of the stapler (10) during use. In this example, the clamping lever cover (56) is attached to and covers the outward-facing side of the clamping lever (40), so that the clamping lever cover (56) is configured to pivot relative to the bin channel (16) with the clamping lever (40). In addition, the anvil cover (78) is attached to and covers the outward-facing side of the anvil channel (60). In some versions, the anvil cover (78) can be connected to the anvil channel (60) via the interaction between the pin (68, 70) and one or more tabs, ribs or other structures, which are arranged in the interior of the anvil cover (78) and include an opening, a slot, a key hole or other feature configured to receive a corresponding one of the pins (68, 70). By way of example only, the covers (56, 78) may be attached using one or more of the teachings of U.S. Pat. No. 11,278,285, which is incorporated by reference above. The covers (56, 78) include a pair of protrusions (13, 15) extending outwardly from the respective covers (56, 78). The pair of protrusions (13, 15) form a larger outer profile than the remainder of the covers (56, 78). In other versions, the covers (56, 78) may be coupled to the clamping lever (40) and the anvil channel (60) in various other suitable ways that would be readily apparent to one of ordinary skill in the art in accordance with the teachings herein.

[0039] like Figure 2 and Figures 5 to 7 As best shown, the proximal end of the magazine half (12) includes a retaining assembly (80) that is configured to releasably retain the anvil half (14) and a portion of the firing assembly (110). The retaining assembly (80) of this example includes a first movable retaining member in the form of an anvil latch member (82) and a second movable retaining member in the form of a stop member (84). The anvil latch member (82) and the stop member (84) are rotatably coupled to the proximal end of the magazine channel (16) via a transversely extending pin (85) disposed proximal to the firing slot (32), and the members (82, 84) are resiliently biased in opposite rotational directions by a resilient member in the form of a torsion spring (86) positioned between the members (82, 84).

[0040] The anvil latch member (82) includes a central body (88), a latch finger (90) extending upwardly from the central body (88), and a release button (92) extending downwardly from the central body (88) through the base wall of the proximal cartridge frame portion (18) of the cartridge channel (16). The upper end of the latch finger (90) tapers distally and is configured to releasably capture the proximal anvil pin (70) of the anvil half (14) with an angled latch surface (94) that overlies the proximal anvil pin (70) once captured. The anvil latch member (82) also includes a pin ejection feature in the form of an angled protrusion (96) extending distally from the base portion of the latch finger (90) and defining an ejection cam ramp (98) facing proximally toward the latch finger (90).

[0041] The stop member (84) of the proximal retention assembly (80) includes a generally cylindrical central body (100), a distal finger (102) extending distally from the central body (100), and a proximal hook (104) extending proximally from the central body (100). The distal finger (102) is configured to releasably engage the proximal end of the firing assembly (110) and thereby retain the firing assembly (110) in a proximal home position. The proximal hook (104) is configured to cover and capture the upper end of the clamp lever latch member (54) when the clamp lever (40) is fully closed and the firing assembly (110) is translated distally from its proximal home position, thereby preventing the clamp lever (40) from opening during the firing stroke, for example, as described in more detail in U.S. Pat. No. 11,278,285, which is incorporated by reference above.

[0042] In use, with the stapler halves (12, 14) coupled together at their proximal ends so that the proximal anvil pin (70) is retained by the anvil latch member (82), and with the clamping lever (40) in the open position, distal actuation of the lower release button (92) causes the anvil latch member (82) to rotate about the pin (85), causing the ejector cam ramp (98) to advance proximally to drive the proximal anvil pin (70) upwardly out of the proximal tapered recess (26) of the cartridge channel (16). The cartridge half (12) of this version also includes a stationary finger gripping projection (106) extending downwardly from the base wall of the proximal cartridge frame portion (18) of the cartridge channel (16) at a location distal to the lower release button (92) and configured to facilitate actuation of the release button (92). Specifically, the user can apply his or her thumb to the proximal side of the release button (92) and one or more fingers to the distal side of the finger gripping protrusion (106), and then squeeze the release button (92) distally toward the stationary finger gripping protrusion (106) to rotate the latch finger (90) out of engagement with the proximal anvil pin (70) and eject the pin (70) upward from the magazine channel (16) using the ejection cam ramp (98).

[0043] The retaining assembly (80) and associated components of the cartridge half (12) may be constructed and operated in accordance with the teachings of one or more of: U.S. Patent No. 10,898,187, entitled “Firing System for Linear Surgical Stapler,” issued on January 26, 2021; and / or U.S. Patent No. 11,033,266, which are incorporated by reference above.

[0044] like Figure 8As shown, the firing assembly (110) of the cartridge half (12) includes a slide (112), a pair of actuators (114, 116) (or "firing knobs") pivotably coupled to the slide (112), and a set of elongated beams (118, 122) extending distally from the slide (112). A pair of side beams (118) are coupled to the distal end of the slide (112) at their proximal ends and terminate distally in a pair of cam ramps (120). The cam ramps (120) are configured to engage the underside of a staple driver (not shown) contained in the staple cartridge (140) and actuate the staple driver upward, thereby driving (or "firing") staples from the cartridge (130) into tissue clamped between the staple cartridge (140) and the anvil plate (72). The central beam (122) is coupled to the side beams (118) via a bridging member (124) (or "knife block") that is distally spaced from the slide (112). The central beam (122) terminates distally in a distally angled knife member (126) having a distal cutting edge (128) configured to cut tissue clamped between the distal portions of the stapler halves (12, 14).

[0045] Each actuator (114, 116) of the firing assembly (110) is configured to be rotatable relative to the slide (112) between a deployed position and a retracted position so that only one actuator (114, 116) can be manually deployed at a time, for example, as disclosed in U.S. Patent No. 10,898,187, which is incorporated by reference above. In the deployed position, the actuator (114, 116) can be driven distally by an operator to actuate the firing assembly (110) to pass distally through the stapler (10), thereby simultaneously cutting and suturing the tissue clamped between the stapler halves (12, 14).

[0046] B. Exemplary Use of a Linear Surgical Stapler

[0047] 9A to 9E An exemplary coupling of stapler halves (12, 14) and subsequent firing of the assembled stapler (10) during a surgical procedure is shown. Fig.9A As shown, the clamping lever (40) of the cartridge half (12) is set in the open position so that the jaw slot (50) is aligned with the distal slot (24) of the cartridge channel side flange (22). In addition, the firing assembly (110) is held in place by the stop member (84) of the retaining assembly (80) (see Figure 5 ) remains in its proximal original position, as described above Figure 5At this stage, the tissue portion to be stapled and cut (not shown) can be positioned above the top of the staple cartridge (140) disposed in the distal jaw portion (20) of the cartridge half (12). Alternatively, after the proximal ends of the stapler half (12, 14) described below are coupled, the tissue can be positioned above the staple cartridge (140).

[0048] like FIG. 9A to FIG. 9B As shown, the proximal ends of the stapler halves (12, 14) are aligned with each other, and the proximal anvil pin (70) (see Figure 2 ) is guided downwardly into the proximal tapered recess (26) of the cartridge channel (16) to engage the latch finger (90) of the anvil latch member (82) (see Figure 5 ). This engagement forces the anvil latch member (82) to resiliently rotate clockwise, thereby enabling the latch finger (90) to capture the anvil pin (70) and thereby releasably couple the proximal ends of the stapler halves (12, 14) together, as shown. Fig. 9B As shown. When the clamping lever (40) is still in the Fig. 9B In the open position shown, the stapler (10) is arranged in a "hanging open" state so that the stapler (10) can be held by the anvil half (14) in one hand while the cartridge half (12) remains coupled to the anvil half (14). Fig. 9C As shown, and with the clamping lever (40) maintained in the open position, the anvil half (14) is rotated about the proximal anvil pin (70) toward the anvil half (14), so that the distal latch pin (68) of the anvil half (14) is received in the distal slot (24) of the cartridge channel side flange (22) and the jaw slot (50) of the clamping lever (40). The distal jaw portions (20, 64) of the stapler half (12, 14) are now in a partially approximated state, allowing final adjustment of the tissue received therebetween before clamping.

[0049] like Fig.9D As shown, the clamping lever (40) is closed to pull the anvil latch pin (68) against the closed proximal end of the jaw slot (50) and thereby fully clamp the anvil half (14) against the cartridge half (12), wherein tissue (not shown) is clamped between the staple cartridge (140) (see Fig.9A ) and anvil plate (72) (see Fig.9A ) between the suture surfaces defined by the staple cartridge (140). Fig.9A ) defines a small lateral gap between the staple cartridge (140) and the anvil plate (72), thereby accommodating tissue therebetween at a predetermined degree of tissue compression. Fig.9A and Fig. 9BAs shown, the tissue gap post (162) is disposed at the distal end of the staple cartridge (140) and is configured to be able to be stapled when the stapler (10) is in Fig.9D In the fully clamped state shown, the distal end of the anvil plate (72) is in contact. In response to the clamping lever (40) reaching the fully closed position, the clamping lever latch member (54) can rotate to capture the proximal end of the base wall of the cartridge channel (16) and thereby assume a latched state in which the clamping lever latch member (54) maintains the clamping lever (40) in the closed position.

[0050] like Fig.9E As shown, when the fully clamped state is reached, the proximal cartridge frame portion (18) (see Fig.9A ) drives the deployed actuator (114, 116) of the firing assembly (110) distally (see Fig.9A ) to fire the stapler (10). This action causes the elongated beams (118, 122) of the firing assembly (110) (see Figure 8 ) is translated distally through a corresponding channel formed in the staple cartridge (140) and thereby fires the staples into the clamped tissue while utilizing the knife member (126) (see Figure 8 ) to cut the clamped tissue. After completing the firing stroke, the firing assembly (110) returns to its proximal original position via the actuators (114, 116). The clamping lever latch member (54) can then be depressed (see Figure 2 ) to release the proximal end of the clamping lever (40) from the bin channel (16), thereby allowing the clamping lever (40) to reopen. The retaining assembly (80) can then be depressed (see Fig.9A ) release button (92) (see Figure 5 ) to release the anvil half (14) from the cartridge half (12) so that the stapler halves (12, 14) can be separated from each other, thereby releasing the newly stapled and severed tissue. It should be understood that in some versions, the stapler (10) may include additional features that facilitate the disengagement of the stapler halves (12, 14), for example, as disclosed in U.S. Pat. No. 11,033,266, which is incorporated by reference above.

[0051] II. Exemplary Electric Firing Platform

[0052] In some cases, it may be difficult for a user to manually apply enough distal force to the actuator (114) to fire the linear surgical stapler (10) to cut and simultaneously sew the clamped tissue layers. Therefore, it may be advantageous to provide a device that can mechanically assist a user in firing the linear surgical stapler (10).

[0053] A. Overview of Electric Surgical Firing Platform

[0054] Figures 10 to 12B An exemplary electric surgical firing assembly (200) is shown, which includes an electric firing platform (202) equipped with the above-mentioned linear surgical stapler (10). It should be noted that the electric firing platform (202) can be integrated with the existing linear surgical stapler (10) backward without any modification to the linear surgical stapler (10). The electric firing platform (202) is configured to provide a mechanical advantage to the user by using a drive assembly (204), which uses electricity or pneumatics to provide electric firing of the linear surgical stapler (10), otherwise the linear surgical stapler will be manually fired by the user. The electric firing platform (202) provides the following advantages: the linear surgical stapler (10) can be removed from the electric firing platform (202) at any time without any tools to manually fire the linear surgical stapler (10). In some cases, the linear surgical stapler (10) may need to be quickly removed from the electric firing platform (202) and fired manually. The electric firing platform (202) enables a user with less strength to provide sufficient uninterrupted force to the firing assembly (110) of the linear surgical stapler (10) to complete the firing stroke. The electric firing platform (202) can be a disposable or reusable component that can be sterilized and used again with the disposable linear surgical stapler (10).

[0055] The electric firing platform (202) includes a body having a handle (206), a housing (208) and an elongated support member (210), and a drive assembly (204) supported by the body. The electric firing platform (202) is made of one or more surgically safe materials, such as plastic, metal, or other materials known in the art that are surgically safe and have suitable rigidity characteristics. The handle (206) is configured to be grasped by a user. As shown, the handle (206) is positioned obliquely relative to the linear surgical stapler (10). More specifically, the handle (206) extends downward from the middle portion of the housing (208) and hangs downward from the middle portion. In some versions, the handle (206) can also be aligned with the elongated support member (210) and attached to the proximal portion of the housing (208) to provide an electric firing platform (202) that includes a smaller cross-sectional area so as to additionally approach the surgical site of the patient's body. The housing (208) is configured to provide a mechanical base and a liquid-tight closure for the drive assembly (204). The housing (208) also serves as a mechanical base for the elongated support (210) extending distally away from the housing (208). The housing (208), the handle (206) and the elongated support (210) can be manufactured into two pieces that can be snap-fitted together or fixed with fasteners (not shown) by blow molding or additive manufacturing. In addition, the housing (208), the handle (206) and the elongated support (210) can be manufactured into a single piece by blow molding or additive manufacturing. In yet other versions, the housing (208), the handle (206) and the elongated support (210) can be manufactured into multiple pieces that are subsequently assembled by molding or additive manufacturing, thereby providing access for maintenance or repair, or making some parts of the electric firing platform (202) can be discarded, while other parts can be sterilized and reused. By way of example only, handle (206) and housing (208) may be reusable, whereas elongated support member (210) may be disposable and replaced.

[0056] The elongated support member (210) includes a proximal portion attached to a distal portion of the housing (208). The elongated support member (210) includes an elongated member (214) extending distally to a bracket (212). The bracket (212) is positioned on the distal end of the elongated member (214). The elongated member (214) includes a guide rail (218), a guide channel (220) and a pair of outer tracks (216). The guide rail (218) includes a generally planar shape and is configured to be able to cooperate with the side surface of the linear surgical stapler (10). In some versions, the profile of the guide rail (218) may be complementary to the side surface of the linear surgical stapler (10). The guide channel (220) is defined by the guide rail (218) on both sides and includes a rectangular shape. The guide channel (220) is sized and shaped to movably support a portion of the drive assembly (204). In some versions, the shape of the guide channel (220) is set to prevent a portion of the drive assembly (204) from deviating from one side to the other side. In this type of formula, the guide channel (220) may include a "T" or "I" shape or another shape known to those of ordinary skill in the art to keep the driver along the longitudinal axis. A pair of outer rails (216) extends roughly parallel to the longitudinal axis of the support and is complementary to the outer profile of the stapler half (12,14). A pair of outer rails (216) may also include a tapered portion (not shown) to help longitudinally position the outer profile of the stapler half (12,14). A pair of outer rails (216) may also include foam or rubber (not shown) positioned on the inner surface of each outer rail in the outer rails (216). The foam or rubber is configured to be able to frictionally engage the outside of the stapler platform (202) when the electric firing platform (202) is navigated to the surgical site. The electric firing platform (202) may need to be inverted or rotated to reach the surgical site. The bracket (212) helps to secure the linear surgical stapler (10) within the electric firing platform (202).

[0057] The bracket (212) includes a pair of C-shaped members (222) extending obliquely from the elongated member (214). The distal portion of each C-shaped member (222) is sized and configured to longitudinally position the surgical linear stapler (10) around the outer contour of the stapler half (12, 14). The C-shaped member (222) can be elastically biased toward the longitudinal axis of the support. Each C-shaped member (222) includes a planar portion (224) and a pair of angled portions (226), which are configured to grasp a pair of protrusions (13, 15) extending from each of the stapler half (12, 14). The bracket may further include foam or rubber, which is configured to frictionally engage the protrusions (13, 15) extending from the pair of C-shaped members (222).

[0058] In some versions, the elongated support member (210) is rotated 90 degrees at the position where it is attached to the distal end of the housing (208). The bracket (212) is configured to be able to orient the anvil above or below the support linear surgical stapler (10), rather than to either side of the linear surgical stapler (10). In this type of formula, the pin (228) is positioned obliquely relative to the handle (206). This type may include a feature incorporated into the bracket (212) or a pair of external tracks (216), which is complementary to the outer profile of the linear surgical stapler (10), so that the linear surgical stapler (10) can be placed in the electric firing platform (202) in only one orientation.

[0059] The drive assembly (204) includes an actuator (230), a forward circuit (232), a reverse circuit (234), and a driver (236). In this version, the drive assembly (204) uses electricity to provide a mechanical advantage to the user to reduce the force required by the user to input the firing assembly (110). The forward circuit and the reverse circuit (232, 234) both include wiring (238) configured to carry current between components of the circuit (232, 234). The forward circuit (232) includes a forward control circuit (240) and a forward main circuit (242). The forward control circuit (240) includes a starter (244) and wiring (238). The starter (244) has a trigger (246) and a forward switch (248). The trigger (246) is rotatably connected to the housing (208) and / or the handle (206). The trigger (246) is configured to be manipulable by a user from a distal position to a proximal position to activate the forward switch (248). The trigger (246) may include a spring (not shown) configured to return the trigger (246) from the proximal position to the distal position after interacting with the forward switch (248). The forward switch (248) is a momentary button including an open position and a closed position. The forward switch (248) in an unactivated state is in a normally open position and in a closed position in an activated state. The forward control circuit (240) actuates the forward relay (250) via the forward switch (248) and the wiring (238).

[0060] The forward main circuit (242) includes a forward relay (250) and wiring (238). The forward relay (250) can be in the form of a conventional electromagnetic relay, a transistor, or another device known in the art that allows the main circuit to provide voltage from the control circuit to the actuator. The forward relay (250) includes an unactuated state and an actuated state. In the actuated state, the forward relay (250) connects the power supply (252) to the actuator (230) via the wiring (238). The forward relay (250) provides a voltage having a first polarity to the actuator (230).

[0061] The power source (252) in this version includes a battery (254). The battery (254) can be a disposable or rechargeable type. The battery (254) can include an alkaline battery, a lithium-ion battery, or other batteries known in the art to provide a compact energy source. In other versions, the battery (254) can be omitted and the electric firing platform (202) can be powered by an external power source (not shown). In these versions, the voltage is supplied by a connector (not shown) and a wire (not shown) that is configured to be connected to a standard wall outlet or to an external battery or other external power supply unit.

[0062] The reverse circuit (234) includes a reverse control circuit (256) and a reverse main circuit (258). It should be noted that the reverse circuit (234) can utilize a portion of the wiring of the forward circuit (232) and is not mutually exclusive. In some cases, the forward and reverse components may include the same components configured to enable the flow of electrons to be reversed. The reverse control circuit (234) includes a reverse switch (260) and wiring (238), and the reverse main circuit (258) includes a reverse relay (262) and wiring (238). The reverse control circuit (234) provides power to actuate the reverse relay (262), which electrically connects the power supply (252) to the reverse relay (262). The reverse switch (260) may be located anywhere on the handle (206) or the housing (208). The reverse switch (260) may include a safety feature that is configured to prevent the inadvertent activation of the reverse switch (260). The reverse switch (260) may also be incorporated into the forward switch (248) or the trigger (246). The reverse main circuit (258) includes a reverse relay (262) that interconnects the battery (254) and the actuator (230) to supply a voltage having a second polarity opposite to the first polarity.

[0063] The actuator (230) may include a motor (264) and a transmission (266), as shown in this version. In other versions, the motor (264) may be replaced by an electric solenoid (not shown). The motor (264) is configured to be supplied with voltage via a forward relay or a reverse relay (250, 262). The motor (264) is rotationally connected to the transmission (266). The transmission (266) may include one or more gears interconnecting the motor (264) to the driver (236). The transmission (266) is configured to be able to change the gear transmission of the motor to provide additional speed or torque to actuate the driver (236). The motor (264) is configured to be able to rotate in a first direction when supplied with a voltage having a first polarity, and to rotate in a second direction opposite to the first direction when supplied with a voltage having a second polarity.

[0064] The driver (236) includes a rack (268), an elongated rod (270), and an engagement feature (272). The rack (268) may include a plurality of linear gear teeth configured to engage with a rotating gear of the transmission (266). The rack (268) is configured to capture a rotational force supplied by the transmission (266) and convert the rotational motion into a linear motion that drives the elongated rod (270) distally when the motor (264) rotates in a first direction, or drives the elongated rod proximally when the motor (264) rotates in a second direction. The rack (268) may also include a lead screw (not shown) or any other device known in the art for converting rotational motion into linear motion. The elongated rod (270) may be integrally formed with the rack (268) and extend distally to the engagement feature (272). The engagement feature (272) is positioned on the distal end of the elongated rod (270) and is configured to be able to cooperate with a portion of the firing assembly (110) and to translate slidably along the guide channel (220). In this version, the engagement feature (272) includes a block (274), a guide (276) and a protrusion shown in the form of an elongated pin (228). The guide (276) includes a shape complementary to the shape of the guide channel (220). As shown, the guide (276) includes a rectangular shape and is configured to translate slidably within the guide channel (220). The pin (228) extends laterally away from the block (274) and is configured to be able to at least partially insert through a portion of the firing assembly (110) of the linear surgical stapler (10) or otherwise cooperate with it. In this version, the pin (228) is assembled in a pin hole (17) defined by the firing assembly (110). Pin (228) is configured to engage firing assembly (110) to translate firing assembly (110) distally or proximally.

[0065] In other versions, the engagement feature (272) may include a slot, channel, recess, or other open feature in place of or in addition to the pin (228) that is sized and shaped to receive and releasably retain a protruding structure of the firing assembly (110), such as a deployed firing actuator (114, 116). In addition, it should be understood that while the electric firing platform (202) of this version is shown and described herein in conjunction with the linear surgical stapler (10), other versions of the electric firing platform (202) may alternatively be configured to receive and engage the firing assemblies of various other types of linear surgical staplers.

[0066] In other versions, the actuator (230) may be combined with a pneumatic device to replace the motor (264). For example, the actuator (230) may be in the form of an air solenoid. The power supply (252) may include compressed gas, such as a disposable CO2 tank or service gas (not shown). The service gas can be supplied to the electric firing platform (202) through a service gas connector. The service gas is remotely generated in an air compressor and supplied to the electric firing platform (202) through a hose. The starting device (244) can be electrical or mechanical. The starting device (244) is either interconnected with an electrically controlled valve (not shown) located between the power supply (252) and the actuator (230), or includes a mechanical valve (not shown) directly connected to the trigger (246).

[0067] Fig.11 A linear surgical stapler (10) is shown spaced apart from and aligned with an electric firing platform (202). The electric firing platform (202) is arranged in a retracted unfired position, wherein the pin (228) is in a proximal position. A pair of protrusions (13, 15) positioned on the outer contour of the stapler half (12, 14) are aligned between a pair of C-shaped members (222), and the remaining outer contour of the stapler half (12, 14) is aligned with a pair of outer tracks (216). In addition, the pin (228) is aligned with a pin hole (280) of a firing assembly (110) extending laterally through the linear surgical stapler (10). The user provides a lateral force on the linear surgical stapler (10) with a first hand, while providing support to the electric firing platform (202) with the other hand, so that the linear surgical stapler (10) is firmly placed in the electric firing platform (202).

[0068] Fig. 12A An electric surgical firing assembly (200) is shown, wherein after the user has performed 9A to 9D After the steps shown, the linear surgical stapler (10) installed in the electric firing platform (202) is in a retracted unfired position. In use, the user manually manipulates the trigger (246) from the distal position to the proximal position. In the proximal position, the trigger (246) engages the forward switch (248), thereby converting the forward switch (248) from the open position to the closed position. The forward switch (248) provides voltage to the forward relay (250) via the forward control circuit (240). The forward relay (250) completes the forward main circuit (242), thereby providing a voltage with a first polarity from the battery (254) to the motor (264).

[0069] Fig. 12BAn electric surgical firing assembly (200) is shown, wherein a linear surgical stapler (10) mounted within an electric firing platform (202) is in an extended firing position after a motor (264) has been provided with a voltage having a first polarity, the voltage causing the motor (264) to rotate in a first direction. The motor (264) is rotatably engaged with a transmission (266) which is rotatably engaged with a rack (268). The rack (268) thereby translates distally. The rack (268) translates the elongated rod (270) distally. The elongated rod (270) moves the pin (228) distally, which moves the firing assembly (110) of the linear surgical stapler (10) distally, thereby clamping one or more tissue layers, cutting through the clamped layers, and simultaneously driving the staples through the layers.

[0070] The electric surgical firing assembly (200) can be returned to a retracted, unfired position by activating a reverse switch (260) (see Fig. 12A ). The reverse switch (260) supplies voltage from the battery (254) to the reverse relay (262). In response to the reverse switch (260) being enabled, the reverse relay (262) supplies voltage having a second polarity from the battery (254) to the motor (264). The motor (264) rotates in a second direction. The motor (264) rotatably engages a transmission (266) which rotatably engages a rack (268) to cause the rack (268) to translate proximally. The rack (268) causes the elongated rod (270) to translate proximally. The elongated rod (270) causes the engagement feature (272) to move proximally, which causes the firing assembly (110) of the linear surgical stapler (10) to move proximally, thereby returning the linear surgical stapler (10) to the retracted position. The linear surgical stapler (10) can be removed, reloaded with a new staple cartridge (140), and FIG. 9A to FIG. 9B The linear surgical stapler (10) can be reinstalled in the electric surgical firing assembly (200), such as Fig.11 shown.

[0071] B. Exemplary Electric Firing Platform with Data Connectivity

[0072] Figures 13 to 14BAnother exemplary electric surgical firing assembly (300) equipped with a linear surgical stapler (310) is shown. The electric surgical firing assembly (300) is similar to the above-mentioned electric surgical firing assembly (200), except that the difference is described in addition below. In this regard, the electric surgical firing assembly (300) includes an electric firing platform (302) and a linear surgical stapler (310), which are combined with additional features that are configured to provide the user with intraoperative knowledge and / or provide the ability to send data to a remote processing unit (referred to herein as a "hub") (304). Such data may relate to the operation of the linear surgical stapler (310) (e.g., the firing speed of the firing assembly or the firing force applied to the firing assembly (110)) and / or the operation of the electric firing platform (302). The electric surgical firing assembly (300) can be used with a linear surgical stapler (310) configured to share and utilize data, or with a conventional linear surgical stapler (10) that does not have such data sharing and utilization capabilities. The conventional linear surgical stapler (10) can be backward integrated into the electric firing platform (302) without any modification to the linear surgical stapler (10) as shown.

[0073] The difference between the electric surgical firing assembly (300) and the electric surgical firing assembly (200) is that the electric surgical firing assembly (300) includes a first electrical connector (306) positioned on the electric firing platform (302) and a second electrical connector (308) positioned on the linear surgical stapler (310). When the linear surgical stapler (310) is positioned in the electric firing platform (302), the first electrical connector (306) is configured to be able to cooperate with the second electrical connector (308). The first connector and the second connector (306, 308) can be spring pin type, Bourns module contact type or any other connector known in the art to provide electrical connection by joining the first connector and the second connector (306, 308) together. As shown in the figure, the first electrical connector (306) is positioned on the bracket (309), and the second connector (308) is positioned on one of the protrusions (13, 15). It should be noted that the first connector and the second connector (306, 308) form a connector assembly (312) when they are mated together. It should be noted that the placement of the connector assembly (312) is only an example of the placement of the connector assembly (312), and the connector assembly (312) can be placed anywhere on the linear surgical stapler (310) including the surface of the electric firing platform (302) that engages. The connector assembly (312) is configured to be able to provide power to electronic devices and sensors positioned on or within the linear surgical stapler (310). For example, the connector assembly (312) can provide power to a printed circuit board (314), a strain gauge (316), a plurality of sensors (322) and other electronic devices (not shown) on or within the linear surgical stapler (310) from a battery (254) positioned within the electric firing platform (302). The connector assembly (312) eliminates the need to place additional batteries in the linear surgical stapler (310) to power sensors and electronic devices.

[0074] The electric firing platform (302) is also different from the electric firing platform (202) in that the electric firing platform (302) includes a platform processor (318). The platform processor (318) may include a memory (320) configured to store predetermined data or real-time data relayed from the linear surgical stapler (310) via the connector assembly (312). The platform processor (318) is configured to apply a metered amount of voltage or current to the actuator (230) when the forward switch (248) is enabled. The platform processor (318) can be used as a supplement or replacement for the forward relay (250). The platform processor (318) uses an algorithm, predefined data parameters and / or real-time data to calculate the metered amount of voltage or current. The real-time data is sent from a sensor (322) via the connector assembly (312) and / or the printed circuit board (314), and the sensor may include, for example, a strain gauge or a photoelectric sensor positioned on the linear surgical stapler (310). The electric surgical firing assembly (300) may further include a platform wireless device (324). The platform wireless device (324) includes a wireless transmitter and a wireless receiver configured to send and receive data from the hub (304). The platform wireless device (324) may have Bluetooth capabilities or include some other wireless compatibility known in the art to send and receive data without a wired connection. The hub (304) may include a hub wireless device (326) and a hub processor (328). The hub processor (328) may also include a hub memory (not shown) configured to store predefined data or real-time data. The hub processor (328) may be configured to calculate firing data using algorithms, real-time data, and predefined data. In some cases, the data may be wirelessly sent back to the platform processor (318) via the hub wireless device (326) and the platform wireless device (324).

[0075] In some cases, data received by the platform processor (318) directly from the sensor (322) or from the hub (304) can be used to implement "smart" firing, wherein the actuator (230) of the electric firing platform (302) is controlled to adjust the firing speed based on the data signal provided by one or more sensors (322). For example, in one example, one or more sensors of the sensor (322) integrated into or on the linear surgical stapler (310) can detect the specific color of the staple cartridge loaded into the linear surgical stapler, and thus detect the specific type of the staple cartridge, and the platform processor (318) can adjust the firing sequence (e.g., firing speed) accordingly. In the same or other examples, one or more sensors of the sensor (322) can detect the firing force applied to the firing assembly (110) of the linear surgical stapler (310), and the platform processor (318) can adjust the firing sequence (e.g., firing speed) accordingly. Exemplary forms of such examples of "smart firing" are described in more detail below.

[0076] In one example of intelligent firing, a tissue thickness sensor (330) positioned within a linear surgical stapler (310) sends a tissue thickness data signal to a platform processor (318) and / or a hub processor (328) via a connector assembly (312). The processors (318, 328) can then calculate appropriate firing sequence data. Based on the firing sequence data, the platform processor (318) can adjust (e.g., increase or decrease) the voltage supplied to the motor (264), wherein an increased voltage increases the speed of the motor (264) and thereby increases the firing speed, and wherein a decreased voltage decreases the speed of the motor (264) and thereby decreases the firing speed.

[0077] In another example of smart firing, a color sensor (332) positioned within a linear surgical stapler (310) may be configured to detect a specific type of staple cartridge (340) loaded into the linear surgical stapler (310) based on the color of the reload. The color sensor (332) may sense color by reading an RFID signature through a printed circuit board (314) or another method known in the art for electronically determining a component. The color data collected by the color sensor (332) is sent to a processor (318, 328) via a connector assembly (312), which may then determine the type of staple cartridge based on the detected color. Based on the determined cartridge type, the platform processor (318) may adjust the speed of the motor (264), and thus adjust the firing speed accordingly, for example based on the preferred firing speed data stored in the memory (320). In this regard, the color data may ultimately enable the processor (318) to determine color-based firing data, which may include a preferred or expected firing speed based on the color of the staple cartridge (340).

[0078] A sensor (322) positioned in the linear surgical stapler (310) may also send real-time data to the processor (318, 328). The real-time data is sent to the processor (318, 328) via the connector assembly (312). The platform processor (318) may then change the firing speed of the linear surgical stapler (310) based on an algorithm using the color-based firing data and / or the real-time data. Predetermined color-based firing data may be stored in the memory (320). The color-based firing data and / or the real-time data may also be communicated to the user. The platform processor (318) may send the color-based firing data and / or the sensed firing data to the hub processor (328) via a wireless device (324, 326). The hub processor (328) sends the color firing data and / or the sensed firing data to a hub user interface (334), such as a digital or LCD screen, for display. The platform processor (318) may also provide feedback to the user using a feedback device (336) positioned within the housing (338). The feedback device may be in the form of a user interface (not shown), a light (not shown), or a tactile feedback device (not shown).

[0079] Fig.14A A linear surgical stapler (310) is shown spaced apart from and aligned with an electric firing platform (302). The electric firing platform (302) is disposed in a retracted, unfired position, wherein the pin (228) is in a proximal position. The first connector (306) does not engage the second connector (308), so that the stapler electronics (322, 330, 316, 314) are not electrically connected to the platform electronics (314, 318, 324, 336). In addition, the battery (254) does not supply power to the stapler electronics (322, 330, 316, 314).

[0080] Fig. 14B A linear surgical stapler (310) is shown, wherein the linear surgical stapler mounted in an electric firing platform (302) is in a retracted unfired position, wherein the pin (228) is engaged with the pin hole (17). The first connector (306) is engaged with the second connector (308) to form a connector assembly (312). The battery (254) supplies power to the stapler electronics (314, 318, 324, 336). The connector assembly (312) provides electrical communication between the stapler electronics (322, 330, 316, 314) and the platform electronics (314, 318, 324, 336). The connector assembly (312) provides electrical communication between the stapler electronics (322, 330, 316, 314) and the hub (304) via the platform wireless device (324) and the hub wireless device (326).
