Abstract
Description
Background Technology
[0001] In some surgical settings, endoscopic surgical instruments may be superior to traditional open surgical devices in creating smaller incisions within the patient, which can reduce postoperative recovery time and complications. Some endoscopic surgical instruments are adapted to place distal end-effectors at desired surgical sites via cannulation of a trocar. These distal end-effectors (e.g., internal cutters, grippers, scalpels, suture devices, clamps, entry devices, drug / gene therapy delivery devices, and energy delivery devices using ultrasound, RF, lasers, etc.) can engage tissue in various ways to achieve diagnostic or therapeutic effects. Endoscopic surgical instruments may include an axis located between the end-effector and a shank portion manipulated by the clinician. This axis allows insertion to the desired depth and rotation about the longitudinal axis of the axis, thereby facilitating the positioning of the end-effector within the patient. Positioning of the end-effector can be further facilitated by including one or more articulation joints or features that allow the end-effector to selectively articulate or otherwise deflect relative to the longitudinal axis of the axis.
[0002] Examples of endoscopic surgical instruments include surgical suture devices. Some of these suture devices are operable to clamp tissue layers, cut through the clamped tissue layers, and drive a staple through the tissue layers to substantially seal the cut tissue layers together near the cut ends. Exemplary surgical suture devices are disclosed only in U.S. Patent No. 7,380,696, published June 3, 2008, entitled “Articulating Surgical Stapling Instrument Incorporating a Two-Piece E-BeamFiring Mechanism”; U.S. Patent No. 8,408,439, published April 2, 2013, entitled “Surgical Stapling Instrument with An Articulatable End Effector”; and U.S. Patent No. 8,453,914, published June 4, 2013, entitled “Motor-Driven Surgical Cutting Instrument with Electric Actuator Directional Control Assembly”. The disclosure of each of the above-cited U.S. patents and U.S. patent publications is incorporated herein by reference.
[0003] Surgical staplers can also be used in open abdominal surgeries and / or other non-endoscopic procedures. By way of example only, in thoracic surgery, a surgical stapler can be inserted via a thoracotomy and thus positioned between the patient's ribs to reach one or more organs, in which a trocar is not used as the catheter for the stapler. For example, blood vessels leading to an organ can be severed and closed using a stapler before it is removed from the thoracic cavity. Of course, surgical staplers can be used in a variety of other situations and procedures.
[0004] Although various surgical suturing instruments and associated components have been manufactured and used, it is believed that no one had manufactured or used the invention described in the appended claims prior to the inventors. Attached Figure Description

[0049] I. Exemplary Surgical Stapler
[0050] Figures 1 to 7 An exemplary surgical suturing and cutting instrument (10) is shown, sized to be inserted into a patient's surgical site via a cannula or incision (e.g., thoracotomy, etc.) to perform a surgical procedure. The instrument (10) of this example includes a shank portion (20) connected to a shaft (22) that terminates distally in an articulation joint (11), which is further coupled to an end effector (12). Once the articulation joint (11) and the end effector (12) are inserted through the cannula's insertion channel, the articulation joint (11) can be remotely articulated via articulation controls (13), such as... Figure 1 The image depicted in the image allows the end effector (12) to deflect from the longitudinal axis (LA) of the shaft (22) at a desired angle (α). The end effector (12) of this example includes a lower jaw (16) and an upper jaw in the form of a pivotable anvil (18), the lower jaw including a staple cartridge (37).
[0051] The handle portion (20) includes a pistol grip (24) and a closing trigger (26). The closing trigger (26) is pivotable toward the pistol grip (24) such that the anvil (18) clamps or closes toward the lower jaws (16) of the end effector (12). Such closure of the anvil (18) is provided by a closing tube (32) and a closing ring (33), both of which translate longitudinally relative to the handle portion (20) in response to the pivoting of the closing trigger (26) relative to the pistol grip (24). The closing tube (32) extends along the length of the shaft (22); and the closing ring (33) is positioned distal to the articulated joint (11). The articulated joint (11) is operable to transfer / transmit longitudinal movement from the closing tube (32) to the closing ring (33).
[0052] like Figure 2As shown, the shank portion (20) also includes a firing trigger (28). An elongated member (not shown) extends longitudinally through the shaft (22) and, in response to actuation of the firing trigger (28), transmits longitudinal firing motion from the shank portion (20) to the firing beam (14). This distal translation of the firing beam (14) causes the tissue clamped in the end effector (12) to be sutured and cut, as will be described in more detail below.
[0053] like Figures 3 to 6 As shown, the end effector (12) employs a firing beam (14) comprising a laterally oriented upper pin (38), a firing beam top cap (44), a laterally oriented middle pin (46), and a distal cutting edge (48). The upper pin (38) is positioned within a longitudinal anvil slot (42) of the anvil (18) and is translatable within said longitudinal anvil slot. The firing beam top cap (44) extends the firing beam (14) through a lower jaw slot (45). Figure 4B The lower surface of the lower jaw (16) is slidably engaged (as shown), and the lower jaw slot is formed through the lower jaw (16). The central pin (46) slidably engages the top surface of the lower jaw (16), thereby cooperating with the firing beam top cover (44).
[0054] Figure 3 This example illustrates the proximal-positioned firing beam (14) and the anvil (18) pivoting to an open configuration, allowing unexploded pellets (37) to be removably inserted into the channel of the lower jaws (16). Figures 5 to 6 As best seen, the staple cartridge (37) in this example includes a cartridge body (70) that presents an upper deck (72) and is coupled to a lower cartridge tray (74). Figure 3 As best seen, a vertical slot (49) extends longitudinally through a portion of the staple cartridge body (70). Similarly... Figure 3 As best seen, three rows of nail holes (51) are formed through the upper deck (72) on each transverse side of the vertical slot (49). Figures 4A to 6 As shown, a wedge-shaped slider (41) and multiple nail actuators (43) are held between the cartridge (70) and the tray (74), wherein the wedge-shaped slider (41) is positioned close to the nail actuators (43). The wedge-shaped slider (41) is capable of longitudinal movement within the nail cartridge (37); while the nail actuators (43) are capable of vertical movement within the nail cartridge (37). The nails (47) are also positioned within the cartridge (70), above the corresponding nail actuators (43). Each nail (47) is vertically driven within the cartridge (70) by the nail actuator (43) to drive the nail (47) outward through the associated nail hole (51). Figures 4A to 4B and Figure 6As is best seen, the wedge slider (41) has an inclined cam surface that pushes the nail driver (43) upward as the wedge slider (41) is driven toward the distal end through the nail cartridge (37).
[0055] By advancing the closing tube (32) and closing ring (33) to the distal end of the actuator (12) as... Figures 4A to 4B In the closed configuration shown, by engaging the upper pin (38) into the longitudinal anvil slot (42), the firing beam (14) is advanced distally until it engages with the anvil (18). Push block (80) Figure 5 Located at the distal end of the firing beam (14), when the firing trigger (28) is actuated, the wedge-shaped slider (41) is pushed distally as the firing beam (14) advances distally through the staple cartridge (37). During this firing, the cutting edge (48) of the firing beam (14) enters the vertical slot (49) of the staple cartridge (37), thereby severing the tissue clamped between the staple cartridge (37) and the anvil (18). Figures 4A to 4B As shown, the intermediate pin (46) and the pusher (80) actuate the nail cartridge (37) together by entering the slot (49) within the cartridge (37), thereby driving the wedge-shaped slider (41) into upward-pushing contact with the nail actuator (43), which in turn drives the nail (47) outward through the nail hole (51) and causes the nail to contact the nail forming recess (53) on the inner surface of the anvil (18). Figure 3 (as shown in the diagram) forms a contact. Figure 4B The firing beam (14) is shown after the tissue has been cut and sutured, and then completely translated distally. From Figures 4A to 4B The nail-shaped recess (53) is intentionally omitted in the view, but... Figure 3 As shown in [the image]. Figure 5 The anvil (18) is intentionally omitted in the view.
[0056] Figure 7 An end effector (12) is shown, actuated through tissue (90) by a single firing stroke. Cutting blade (48) Figure 7 The tissue (90) has been cut through (the obscured area), and the staple driver (43) has driven three rows of alternating staples (47) through the tissue (90) on each side of the cutting line created by the cutting edge (48). After the first firing stroke is completed, the end effector (12) is withdrawn from the patient and replaced with a new staple cartridge (37). The end effector (12) is then reinserted into the patient to reach the suture site for further cutting and suturing. This process can be repeated until the desired number and pattern of firing strokes across the tissue (90) have been completed.
[0057] The device (10) may be further constructed and operated in accordance with any of the teachings of the following references, the disclosures of which are incorporated herein by reference: U.S. Patent No. 8,210,411, entitled “Motor-Driven Surgical Instrument,” published July 3, 2012; U.S. Patent No. 9,186,142, entitled “Surgical Instrument End Effector Articulation Drive with Pinion and Opposing Racks,” published November 17, 2015; U.S. Patent No. 9,517,065, entitled “Integrated Tissue Positioning and Jaw Alignment Features for Surgical Stapler,” published December 13, 2016; U.S. Patent No. 9,622,746, entitled “Distal Tip Features for End Effector of Surgical Instrument,” published April 18, 2017; and U.S. Patent No. 9,622,746, entitled “Lockout Feature for Movable,” published August 1, 2017.

[0058] II. Exemplary support assembly and support applicator compartment
[0059] In some cases, it may be desirable to equip the end effector (12) of the surgical instrument (10) with an adjunct material (such as a support) to reinforce the tissue mechanical fastening provided by the staples (47). This support prevents the applied staples (47) from being pulled through the tissue and may otherwise reduce the risk of tissue tearing at or near the site of the applied staples (47). In addition to providing structural support and integrity for a row of staples (47) or as an alternative, the support may provide a variety of other effects, such as gap or interstitial filling, administration of therapeutic agents, and / or other effects. In some cases, the support may be disposed on the upper deck (72) of the staple cartridge (37). As described above, the deck (72) houses the staples (47) driven by the staple driver (43). In some other cases, the support may be disposed on the surface of the anvil (18) facing the staple cartridge (37). It should also be understood that a first support may be disposed on the deck (72) of the staple cartridge (37), while a second support may be disposed on the anvil (18) of the same end effector (12).
[0060] Various examples of the forms in which the support may take will be described in more detail below. Various ways in which the support may be attached to the staple cartridge (37) or the anvil (18) will also be described in more detail below. Exemplary support assemblies, exemplary materials and techniques for applying the support assembly, and exemplary support applicator cartridges may be constructed in accordance with at least some of the teachings of the following patents, the disclosures of which are incorporated herein by reference: U.S. Patent No. 10,166,023, entitled “Method of Applying a Buttress to a Surgical Stapler End Effector,” published January 1, 2019, and / or U.S. Patent No. 10,349,939, entitled “Method of Applying a Buttress to a Surgical Stapler,” published July 16, 2019.
[0061] A. Exemplary components of the support assembly
[0062] Figure 8An exemplary pair of support assemblies (110, 112) (each also individually referred to as a “support”) are shown. The support assembly (110) of this example includes a support body (114) and an upper adhesive layer (116). Similarly, the support assembly (112) includes a support body (118) and a lower adhesive layer (120). In this example, each support body (114, 118) includes a strong yet flexible material configured to structurally support a row of nails (47). By way of example only, each support body (114, 118) may include a mesh of polyglactin 910 material from Ethicon Ltd. (Somerville, New Jersey). Alternatively, in addition to polyglactin 910 material, or as an alternative, any other suitable material or combination of materials may be used to form each support body (114, 118).
[0063] Each support body (114, 118) may include materials including, for example, hemostatic agents such as fibrin to aid in blood clotting and reduce bleeding at surgical sites along tissue (T1, T2) cuts and / or sutures. As another illustrative example only, each support body (114, 118) may include other adjuvants or hemostatic agents such as thrombin, which may be used to enable each support body (114, 118) to aid in blood clotting and reduce bleeding at surgical sites. Other adjuvants or agents that may be incorporated into each support body (114, 118) may also include, but are not limited to, medical fluids or matrix components.
[0064] In this example, an adhesive layer (116) is applied to the support body (114) to adhere the support body (114) to the underside (124) of the anvil (18). Similarly, an adhesive layer (120) is applied to the support body (118) to adhere the support body (118) to the upper deck (72) of the staple cartridge (37). Such adhesive material provides proper positioning of the support body (114, 118) before and during actuation of the end effector (12); and then allows the support body (114, 118) to separate from the end effector (12) after the end effector (12) has been actuated without damaging the support body (114, 118) in a manner sufficient to impair its proper subsequent function.
[0065] B. Exemplary sutures for tissue and support components
[0066] Figures 9A to 9CAn exemplary sequence is shown in which a surgical suture end actuator (12), in which a support assembly (110, 112) is already loaded, is actuated to drive a staple (47) through two opposing tissue layers (T1, T2), wherein the support assembly (110, 112) is secured to the same tissue layer (T1, T2) by the staple (47). Specifically, Figure 9A Tissue layers (T1, T2) positioned between the anvil (18) and the cartridge (37) are shown, with the anvil (18) in the open position. A support assembly (110) is adhered to the underside (124) of the anvil (18) via an adhesive layer (116); while a support assembly (112) is adhered to the upper deck (72) of the cartridge (37) via an adhesive layer (120). Thus, tissue layers (T1, T2) are interposed between the support assemblies (110, 112). Next, the closure trigger (26) pivots toward the pistol grip (24) to drive the closure tube (32) and closure ring (33) distally. This drives the anvil (18) to... Figure 9B The closed position is shown. At this stage, the tissue layers (T1, T2) are compressed between the anvil (18) and the cartridge (37), wherein the support assemblies (110, 112) engage the opposing surfaces of the tissue layers (T1, T2). The end effector (12) is then actuated as described above, thereby driving the staple (47) through the support assemblies (110, 112) and the tissue (T1, T2). As shown in FIG13C, the crown (122) of the driven staple (47) abuts against the tissue layer (T2) to capture and retain the support assembly (112). The deformable leg (126) of the staple (47) abuts against the tissue layer (T1) to capture and retain the support assembly (110).
[0067] Similarly, a series of pins (47) abut against the tissue layers (T1, T2) to capture and retain the support assembly (110, 112), thereby securing the support assembly (110, 112) to the tissue (T1, T2), as... Figure 10 As shown. Because the end effector (12) is pulled away from the tissue (T1, T2) after the deployment of the pins (47) and the support assembly (110, 112), the support assembly (110, 112) disengages from the end effector, so that the support assembly (110, 112) is held fixed to the tissue (T1, T2) by the pins (47). The supports (110, 112) thus provide structural reinforcement for the rows of pins (47) formed in the tissue (T1, T2). Additionally, as... Figure 10 It can be seen that the cutting edge (48) of the firing beam (14) on the far side also cuts through the centerline of the support tissue assembly (110, 112), thereby dividing each support assembly (110, 112) into a corresponding pair of segments, so that each segment remains fixed to the corresponding cut area of the tissue (T1, T2).
[0068] C. An exemplary support applicator compartment with a movable retainer arm
[0069] Because the end effector (12) of the surgical instrument (10) can be actuated multiple times during a single surgical procedure, it may be desirable to enable the operator to repeatedly and easily load the support assembly (110, 112) onto the end effector jaws (16, 18) during the single surgical procedure. Figures 11 to 13B An exemplary support applicator compartment (210) (also referred to as a "support applicator") is shown, which can be used to support, protect, and apply auxiliary materials, such as support assemblies (110, 112), to an end effector (12). Figures 11 to 12 As best seen in the present example, the compartment (210) includes an open end (212) and a closed end (214). The open end (212) is configured to receive an end actuator (12), as will be described in more detail below. The compartment (210) also includes a first housing (216a) and a second housing (216b), each of which together generally defines a “U” shape to present the open end (212). A platform (218) and a slider retainer (220) are interposed between the first housing (216a) and the second housing (216b).
[0070] The platform (218) of this example is configured to support a pair of support assemblies (110) on one side of the platform (218) and another pair of support assemblies (112) on the other side of the platform (218). The platform (218) is exposed in a recess formed between the forks of the “U” configuration of the first housing (216a) and the second housing (216b). Each support assembly (110, 112) is disposed in a separate corresponding pair of portions to avoid crossing the slots (42, 49) of the anvil (18) and the staple cartridge (37), but the platform (218) can equally easily support a wide-type support assembly (110, 112) that crosses the slots (42, 49) of the anvil (18) and the staple cartridge (37) individually, respectively. More specifically, the outer edge of the platform (218) includes a ridge-shaped retaining feature (530) that further engages the first housing (216a) and the second housing (216b) to prevent the platform (218) from sliding relative to the first housing (216a) and the second housing (216b).
[0071] The first housing (216a) and the second housing (216b) include an integral gripping feature (222) and an indicator plate (224) positioned to correspond to a window (226) formed in the first housing (216a) and the second housing (216b), such that the indicator plate (224) is visible through the window (226) at different times. The arm (228) of this example is configured to selectively secure the support assembly (110, 112) to the platform (218). The arm (228) of this example is elastic and is therefore configured to elastically abut against the support assembly (110, 112), thereby causing the support assembly (110, 112) to retract against the platform (218). The support applicator compartment (210) includes a pair of cam surfaces (232) with gradually changing cross-sections and a corresponding pair of housing engagement features (234) positioned to engage corresponding surfaces of the first housing (216a) and the second housing (216b). The first housing (216a) and the second housing (216b) include a proximal guide feature (236) and a distal guide feature (238) configured to assist in providing proper alignment of the end effector (40) with the housing (210).
[0072] Figure 13A A compartment (210) is shown in which the retainer arm (228) is positioned against the platform (218) to hold the support assembly (110, 112); while Figure 13B A compartment (210) is shown in which the retainer arm (228) is positioned to release the support assembly (110, 112) from the platform (218). Figures 13A to 13B Only the support assembly (110) on the platform (218) is shown; the support assembly (112) is held on and released from the platform (218) in the same manner. To use the bin (210) to load the end effector (12), the operator will first position the bin (210) and the end effector (12) such that the end effector is aligned with the open end (212) of the bin (210), as shown. Figure 13A As shown. The operator then advances the end effector (12) distally and / or the cartridge (210) proximally to position the platform (218) and support assemblies (110, 112) between the anvil (18) and the staple cartridge (37), as shown. Figure 13BAs shown. Then, the operator squeezes the closing trigger (26) of the instrument (10) to close the end effector jaws (16, 18) on the platform (218), thereby adhering the support assembly (110, 112) to the anvil (18) and the cartridge (37), and simultaneously pressing the cam surface (232). The pressing of the cam surface (232) laterally actuates the retainer arm (228), thereby releasing the support assembly (110, 112) from the platform (218), so that the end effector jaws (16, 18) can disengage from the platform (218), while the support assembly (110, 112) remains adhered to the anvil (18) and the cartridge (37).
[0073] III. An exemplary alternative application device with authentication features and for applying support to the end of a surgical suture device. Related methods for actuators
[0074] In some cases, it may be desirable to provide an application device configured to apply a staple-reinforcing accessory to one or both jaws of a surgical stapler end effector while the jaws remain open, or otherwise prevent the jaws from closing via actuation of the end effector closure system of the stapler (such as via actuation of the closure trigger (26) of the surgical stapler (10). The exemplary application devices described below provide such functionality, such that each application device is configured to be manipulated relative to the end effector to apply the accessory to one or both jaws without requiring the aforementioned... Figures 13A to 13B The jaws shown are actuated and closed. In addition, the exemplary application device described below is operable to apply minimal pressure to properly place the auxiliary material onto the desired jaws (e.g., the lower jaw (16) or the anvil (18)).
[0075] Furthermore, in such examples, it may be desirable for such application devices to include certain features to facilitate alignment between the jaws of the application device and the end effector. Such features may additionally or alternatively be used to prevent the reuse of such application devices, end effectors, or both. Such features may additionally or alternatively be used to authenticate such application devices with a given end effector to facilitate the use of such application devices having only a specific, predetermined end effector or an end effector with a specific, predetermined configuration.
[0076] It should be understood that any of the exemplary application devices described below can be configured to apply the auxiliary element in the form of a support (such as the aforementioned support (110, 112)) or a tissue thickness compensator (e.g., of the type disclosed in U.S. Patent Publication No. 2012 / 0080336, entitled “Staple Cartridge Comprising Staples Positioned Within A Compressible Portion Thereof,” published April 5, 2012 and now abandoned, the disclosure of which is incorporated herein by reference). Additionally, the application of the nail reinforcement element to the end effector jaws can be achieved using adhesive features as described above and / or mechanically connected features (e.g., of the type disclosed in U.S. Patent No. 7,665,646, entitled “Interlocking Buttress Material Retention System,” published February 23, 2010, the disclosure of which is incorporated herein by reference). Furthermore, any of the exemplary application devices described below can be suitably configured for single or multiple use.
[0077] A. An exemplary alternative application device with a locking element
[0078] Figure 14A An exemplary alternative support applicator compartment (410) (also referred to as a “support applicator”) is shown, which can be used to support, protect, and apply auxiliary materials, such as support assemblies (110, 112), to an end effector (12). Except where explicitly described elsewhere herein, the support applicator compartment (410) of this example is substantially similar to the support applicator compartment (210) described above. For example, like the compartment described above, the compartment (410) of this example includes an open end (412) and a closed end (414). Like the open end (212) described above, the open end (412) of this example is configured to receive the end effector (12), as will be described in more detail below. Similarly, the compartment (410) of this example also includes a first housing (416a) and a second housing (416b), each of which together generally defines a “U” shape to present the open end (412). Similarly, a platform (418) is inserted between the first housing (416a) and the second housing (416b).
[0079] Similar to the platform (218) described above, the platform (418) of this example is configured to support a pair of support assemblies (110) on one side of the platform (418) and another pair of support assemblies (112) on the other side of the platform (418). The platform (418) is exposed in a recess formed between the forks of the “U” configuration of the first housing (416a) and the second housing (416b). Each support assembly (110, 112) is disposed in a separate, corresponding pair of portions to avoid crossing the slots (42, 49) of the anvil (18) and the staple cartridge (37), but the platform (418) can equally easily support a wide-type support assembly (110, 112) that crosses the slots (42, 49) of the anvil (18) and the staple cartridge (37) individually, respectively.
[0080] Unlike the platform (218) described above, the platform (418) of this example is typically configured to expand in one or more directions to apply the support components (110, 112). As will be described in more detail below, this functionality can be achieved by the platform (418) operating as an expandable wedge. By way of example only, in some examples, this functionality can be achieved by constructing other suitable features of the platform (418) or the container (410) in accordance with at least some of the teachings of the following U.S. patent application: U.S. Patent Application No. END9286USNP2, filed on the same date as this application, entitled “Apparatus and Method to Apply Buttress to End Effector of Surgical Stapler via Driven Member,” the disclosure of which is incorporated herein by reference.
[0081] Similar to the aforementioned housing (210), the first housing (416a) and the second housing (416b) include a gripping feature (422). However, unlike the gripping feature (222) described above, the gripping feature (422) in this example is movable to selectively expand the platform (418). As will be described in more detail below, the gripping feature (422) is generally configured to translate relative to the housings (416a, 416b), thereby activating the expansion of the platform (418). Also as will be described in more detail below, it should be understood that in some configurations, the gripping feature (422) may be locked to prevent platform expansion or otherwise deactivate the application of the support assembly (110, 112) to the housing (410).
[0082] Unlike the aforementioned compartment (210), the compartment (410) of this example includes a locking assembly (440) disposed within the housing (416a, 416b). The locking assembly (440) is generally configured to prevent the platform (418) from expanding until the compartment (410) is properly positioned within the end effector (12), thereby preventing improper application of the support assemblies (110, 112). In other words, the locking assembly (440) is generally configured to allow deployment of the support assemblies (110, 112) only when the locking assembly (440) is engaged at a predetermined portion of the end effector (12). Such engagement can then be used to allow movement of the gripping feature (422) to activate expansion or other movement of the platform (418).
[0083] The locking assembly (440) of this example is positioned near the opening end (412) and includes two actuators (442) extending inwardly from either side of its compartment (410) into the opening end (412). Each actuator (442) includes an engagement portion (444), a spring collar (446), a release opening (448), and a locking end (449). Although not shown, it should be understood that each actuator (442) in this example is constructed as an elongated rod, I-beam, or other elongated structure. Of course, various other suitable cross-sectional shapes that may be used for each actuator (442) will be apparent to those skilled in the art in light of the teachings herein.
[0084] The engagement portion (444) of each actuator (442) defines a length suitable for extending from the housing (416a, 416b) into the opening end (412). In this example, this extension length of each engagement portion (444) is approximately equal to half the lateral length of the opening end (412). Thus, the engagement portions (444) of each actuator (442) extend toward each other to collectively occupy the entire lateral length of the opening end (412). Alternatively, the engagement portions (444) of each actuator (442) may collectively occupy a large portion of the lateral length of the opening end (412) to define a small gap at the end of each engagement portion (444). As will be described in more detail below, such gaps between the engagement portions (444) may be intended to facilitate movement of each actuator (442) by engaging with a portion of the end effector (12).
[0085] A spring collar (446) is positioned along the length of each actuator (442) between a corresponding engagement portion (444) and a release opening (448). The spring collar (446) is typically configured to engage a spring (450) disposed within one or more housings in the housings (416a, 416b) to bias each actuator (442) toward a predetermined position. In this example, the combination of the spring collar (446) and the spring (450) is configured to bias each actuator (442) toward a corresponding... Figure 14A The locking position is biased in the configuration shown. As will be described in more detail below, each actuator (442) is positioned to prevent movement of the corresponding gripping feature (442) when in the locked position.
[0086] A release opening (448) is defined within each actuator (442) near the locking end (449). As will be described in more detail below, the release opening (448) is generally configured to receive a portion of the corresponding gripping feature (422). To facilitate this configuration, each release opening (448) corresponding to each actuator (442) extends from one side through the actuator (442) to the other side. Thus, each release opening (448) is configured to extend through a through-hole of the corresponding actuator (442).
[0087] Adjacent to the release opening (448), a locking end (449) of each actuator (442) is positioned on its outermost end. Each locking end (449) is generally configured to prevent movement of a portion of the corresponding gripping feature (422). Thus, it should be understood that the locking end (449) has a generally solid configuration. As will be described in more detail below, each actuator (442) is generally configured to be laterally sculpted within the chamber (410) to switch between engaging a portion of the gripping feature (422) with the locking end (449) or engaging a portion of the gripping feature (422) with the release opening (448).
[0088] To facilitate engagement between the gripping feature (422) and the locking assembly (440), each gripping feature (422) includes a locking arm (424). Specifically, each locking arm extends axially or proximally from the body of each gripping feature (422) toward each actuator (442) through the chamber (410). Each locking arm (424) is generally configured as an elongated rod or beam having a cross-section corresponding to the shape of a respective release opening (448). As will be described in more detail below, each locking arm (424) is configured to be received within the respective release opening (448) to allow movement of the gripping feature (422).
[0089] like Figure 14A and Figure 14B As best viewed, the locking assembly (440) generally responds to a predetermined portion of the end effector (12) to lock and unlock movement of the gripping feature (422). Figure 15A and Figure 15B As seen, the unlocking movement of the gripping feature (422) allows activation of the compartment (410) via the gripping feature (422) to expand the platform (418). Therefore, the locking assembly (440) is configured to be able to... Figure 14A The locking configuration shown transforms into Figure 14B The unlocking configuration is shown. This change allows the gripping feature (422) to be used to activate the expansion of the platform (418), such as Figure 15B As seen in the text.
[0090] like Figure 14A As seen, in the locking configuration, each actuator (442) of the locking assembly (440) is positioned inward such that each engaging portion (444) is in near contact (or alternatively in contact) with the opposite engaging portion (444). Correspondingly, each locking end (449) is positioned adjacent to the proximal end of the corresponding locking arm (424). Thus, when the locking assembly (440) is in the locking configuration, each locking end (449) prevents movement of each gripping feature (442) via the locking arm (424). Additionally, it should be understood that the locking assembly (440) is biased toward the locking configuration by a spring (450) and a spring collar (446).
[0091] The transition of the locking assembly (440) from a locking configuration to an unlocking configuration is in Figure 14BAs shown in the figure, the transformation of the locking assembly (440) is driven by a predetermined portion of the end effector (12). In this example, this transformation is driven by the cutting edge (48) of the end effector (12). The use of the cutting edge (48) in this example is generally desirable because the specific shape, size, and position of the cutting edge (48) can be unique to the end effector (12). Therefore, the use of the cutting edge (48) as described herein serves as a locking feature to facilitate the use of the chamber (410) only with certain specific end effectors corresponding to the end effector (12) described above. In other words, end effectors with configurations different from those of the end effector (12) described above may not be usable with the chamber (410). It is also desirable to use the cutting edge (48) as described herein to prevent the deployment of the support assemblies (110, 112) until the chamber (410) is properly positioned within the end effector (12). Although the cutting edge (48) is shown and described herein as being used to drive the locking assembly (440), it should be understood that in other examples, various alternative portions of the end effector (12) may be used to drive the transformation of the locking assembly (440). It should be understood that suitable portions of the end effector (12) may include any part of the end effector (12) that is unique or different from other end effector configurations or styles.
[0092] Returning to this example, the locking assembly (440) is transformed by engagement between the engagement portion (444) of each actuator (442) and the cutting edge (48) of the end effector (12). Specifically, the chamber (410) is inserted into / on the end effector (12) (or the end effector (12) is inserted into / on the chamber (410)) to bring the cutting edge (48) into contact with each engagement portion (444). This contact pushes each actuator (442) outward away from the opposite actuator (442) by a predetermined distance. Once this predetermined distance is reached, as Figure 14B As shown, each release opening (448) is positioned adjacent to the proximal end of the corresponding locking arm (424). This allows each locking arm (424) to be received within the corresponding release opening (448). Therefore, each gripping feature can be translated proximally relative to the housing (416a, 416b).
[0093] like Figure 15BAs shown, once the locking assembly (440) transitions to the unlocked configuration, each gripping feature (422) can move proximally to activate the expansion of the platform (418). This expansion pushes the platform (418) toward the upper deck (72) and the anvil (18) of the end effector (12) to deploy the support assemblies (110, 112) thereon. Although not shown, it should be understood that the gripping features (422) can communicate with one or more features adapted to activate the expansion of the platform (418). In this example, the gripping features (422) are used to drive the linkage assembly to expand the platform (418). As described above, the expansion of the platform (418) can be achieved using a variety of mechanical and / or electrical configurations.
[0094] B. An exemplary alternative application device with keyed release
[0095] Figure 16 Another exemplary support applicator compartment (510) (also referred to as a “support applicator”) is shown, which can be used to support, protect, and apply auxiliary materials, such as support assemblies (110, 112), to an end effector. Except where explicitly described elsewhere herein, the support applicator compartment (510) of this example is substantially similar to the support applicator compartments (210, 410) described above. For example, like compartment (410), compartment (510) of this example includes a housing (not shown) defining an open end (not shown) and a closed end (not shown). Similarly, a platform (518) is inserted between one or more portions of the housing.
[0096] Similar to the platform (418) described above, the platform (518) of this example is configured to support a pair of support assemblies (110) on one side of the platform (518) and another pair of support assemblies (112) on the other side of the platform (518). Also similar to the platform (418), the platform (518) of this example is generally configured to expand to accommodate the support assemblies (110, 112). To support this expandability, the platform (518) includes an upper support (520) and a lower support (522) connected to a hinge (526). The upper support (520) includes an elongated, flat surface configured to support the support assemblies (110). Similarly, the lower support (522) also includes an elongated, flat surface configured to support the support assemblies (112).
[0097] The upper support (520) is connected to the lower support (522) at a hinge (526). The hinge (526) is positioned at the proximal end of each support (520, 522) such that the hinge (526) is generally configured for insertion into an end effector (612), as will be described in more detail below. The hinge (526) is generally configured to allow pivoting of the upper support (520) relative to the lower support (522).
[0098] The platform (518) of this example is configured to expand automatically (e.g., without the operator pushing or pulling any part of the platform (518)). To facilitate such automatic expansion, the platform (518) of this example also includes an elastic member or torsion spring (530) and a damper (532). The torsion spring (530) is configured to provide an outward force against the upper support (520) and the lower support (522) to bias the platform (518) toward the expansion configuration. Meanwhile, the damper (532) is generally configured to provide a controlled force opposite to that of the torsion spring (530) (e.g., an inwardly oriented force). It should be understood that the damper (532) is generally configured to act as a damper to prevent the torsion spring (530) from expanding the platform (518) at an undesirable rate. By way of example only, in some instances, this functionality may be implemented by constructing a platform (518) or a warehouse (510) by means of at least some of the teachings of the following U.S. patent application: U.S. patent application entitled “Apparatus and Method to Apply Buttress to End Effector of Surgical Staplervia Driven Member” [Attorney’s File No. END9286USNP2], filed on the same date as this application, the disclosure of which is incorporated herein by reference.
[0099] To activate the expansion of the platform (518), the bin (510) of this example also includes a release component (540). The release component (540) is typically configured to engage a predetermined portion of the end effector (612) to activate the expansion of the platform (518) upon such engagement. Thus, the release component (540) is similar to the locking component (440) described above, since the release component (540) facilitates the use of the bin (510) only with certain end effectors and also facilitates the activation of the bin (510) only when the bin (510) is properly positioned within such end effectors.
[0100] The release assembly (540) of this example includes a probe (542) and a latch (548). The probe (542) includes a keyed end (544) and an elongated pusher (546) extending from the keyed end (544). A portion of the probe (542) extends proximally from the hinge (526) such that the keyed end (544) protrudes from the proximal end of the housing (510). As will be described in more detail below, a particular position of the probe (542) is configured to allow engagement between the keyed end (544) and a predetermined portion of the end actuator (610) when the lower support (522) is properly positioned within the end actuator (612).
[0101] An elongated actuator (546) extends distally from the hinge (526) and the key end (544) toward the torsion spring (530) and the latch (548). The elongated actuator (546) is generally responsive to movement of the key end (544), such that movement of the key end (544) causes a corresponding movement of the elongated actuator (546). As will be described in more detail below, the movement of the elongated actuator (546) is configured to actuate the latch (548), which releases the torsion spring (530) and thereby expands the platform (518).
[0102] A latch (548) is typically configured to selectively engage a torsion spring (530) to retain the torsion spring (530) in a compression configuration. In this example, the latch (548) comprises an elongated rod or wire including a connector (550) and a release member (552). The connector (550) is pivotally coupled to a lower support member (522) to allow the latch (548) to pivot relative to the lower support member (522). The release member (552) is positioned opposite the connector (550) and is configured to releasably engage the torsion spring (530) and / or a portion of the upper support member (520) to retain the torsion spring (530) in a compression configuration. As will be described in more detail below, the elongated pusher (546) is generally configured to engage the latch (548) to pivot the latch (548) about the connector (550), thereby disengaging the release member (552) from a portion of the torsion spring (530) and / or the upper support member (520).
[0103] Although the release assembly (540) is shown in a particular configuration, it should be understood that a variety of alternative configurations may be used in other examples. For example, in some examples, other mechanical release mechanisms may be used to allow the platform (518) to expand selectively via a torsion spring (530) or other mechanisms configured to store potential energy. In other examples, the release assembly (540) may use a variety of electrical / mechanical components, such as solenoids, motors, buttons, sensors, etc. Of course, various other suitable configurations of the release assembly (540) will be apparent to those skilled in the art in light of the teachings herein.
[0104] like Figure 17AAs seen herein, the cartridge (510) of this example is configured to be used with an end effector (612). Except where otherwise explicitly stated herein, the end effector (612) of this example is substantially similar to the end effector (12) described above. For example, similar to the end effector (12) described above, the end effector (612) of this example employs a firing beam (614) which can be used to cut and suture tissue in a single stroke. As with the firing beam (14) described above, the firing beam (614) of this example can be driven relative to an anvil (not shown) (similar to anvil (18)) and an unexploded staple cartridge (not shown) (similar to staple cartridge (37)) to cut and suture tissue. As with staple cartridge (37), the staple cartridge of the end effector (612) is removably mounted into a channel of the lower jaw (616).
[0105] Unlike the end effector (12) described above, the end effector (612) of this example includes a cartridge closure (630) integrated into the end effector (612). The closure (630) is typically configured to engage with certain corresponding parts of the cartridge. Such an engagement arrangement moves the closure (630) to a predetermined position and unlocks certain operations of the end effector (612), such as the movement of the firing beam (614) and the closure of the anvil. Therefore, it should be understood that the closure (630) is configured to prevent the use of the end effector (612) when the cartridge is not installed, an improperly installed (e.g., lacking engagement features) cartridge is installed, or the cartridge is improperly installed. In some examples, the end effector (612) and the locking element (630) of the staple cartridge, and other associated features may be constructed in accordance with at least some of the teachings of the following patent: U.S. Patent Application No. 16 / 453,273, filed June 26, 2019, entitled “Method for Providing an Authentication Lockout in a Surgical Stapler with a Replaceable Cartridge,” the disclosure of which is incorporated herein by reference.
[0106] exist Figures 17A to 18 The use of the support applicator compartment (510) with an end effector (612) is shown. Figure 17A In the best-viewed position, the bin (510) can first be inserted into the end effector (612) to position the lower support (522) aligned with the lower jaw (616) of the end effector (612). The insertion direction is such that the hinge (526) and the key end (544) are inserted into the end effector (612) first toward the locking member (630).
[0107] Once the housing (510) is fully inserted into the end effector (612), the keyed end (544) engages a portion of the locking element (630), as... Figure 17B As seen in the example. In some examples, the specific geometry of the key end (544) may be configured to correspond to specific geometric features of the locking element (630) to further facilitate precise positioning of the chamber (510) relative to the end actuator (612). In any case, when the key end (544) engages with the locking element (630), the key end (544) pushes the probe (542) distally.
[0108] like Figure 18 As the probe (542) moves distally, the elongated pusher (546) engages the latch (548). The latch (548) is correspondingly pushed by the elongated pusher (546) to pivot about the connector (550), thereby disengaging the release member (552) from the torsion spring (530) and / or the upper support member (520). With the torsion spring (530) released, the platform (518) can expand at a controlled speed using the force applied by the torsion spring (530) and the buffer (532) to apply the support assembly (110, 112) to the end effector (612).
[0109] C. Exemplary alternative application device with RFID certification
[0110] Figure 19A and Figure 20A Another exemplary alternative support applicator compartment (710) (also referred to as a “support applicator”) is shown, which can be used to support, protect, and apply auxiliary materials, such as support assemblies (110, 112), to an end effector. Except where explicitly described herein, the support applicator compartment (710) of this example is substantially similar to the support applicator compartments (210, 410, 510) described above. For example, like compartment (410), compartment (710) of this example includes a housing (716) defining an open end (712) and a closed end (714). Similarly, a platform (718) is inserted between one or more portions of the housing.
[0111] Similar to the platform (418) described above, the platform (718) of this example is configured to support a pair of support assemblies (110) on one side of the platform (718) and another pair of support assemblies (112) on the other side of the platform (718). Also similar to the platform (418), the platform (718) of this example is generally configured to expand to apply the support assemblies (110, 112). To support this expandability, the platform (718) includes certain mechanisms generally configured to facilitate its expansion. By way of example only, the platform (718) of this example includes an expandable wedge driven by a linkage mechanism similar to that of the platform (418) described above. However, it should be understood that other suitable mechanisms, such as expandable airbags, spring-loaded wedges, lead screw drives, etc., may be used in other examples. In other examples, the platform (718) may be constructed based on at least some of the teachings of the following patent: U.S. patent application entitled “Apparatus and Method to Apply Buttress to End Effector of Surgical Stapler via DrivenMember” [Attorney’s File No. END9286USNP2], filed on the same date as this application, the disclosure of which is incorporated herein by reference.
[0112] Unlike the platform (418) described above, the scalability of the platform (718) in this example is motor-driven rather than manually operated. Specifically, as Figure 20A As best seen, the interior of the chamber (710) includes a motor (730), a power source (734), and a switch (738), all integrated into a circuit. Although not shown, it should be understood that the motor (730) of this example can communicate with one or more features of the platform (718) to drive the expansion of the platform (718). For example, as described above, the platform (718) of this example can use a linkage mechanism to provide its expansion. Thus, in such examples, the motor (730) can be configured to rotate a lead screw or other drive mechanism to move the platform (718) from a flat configuration to an expanded configuration. Of course, in other configurations using alternative expansion mechanisms, the motor (730) can vary as needed. For example, in some examples, the motor (730) can include a vacuum pump, a linear actuator, etc.
[0113] The switch (738) communicates with the motor (730) and the power source (734) to selectively activate and deactivate the power supplied to the motor (730) via the power source (734). The power source (734) in this example is shown as a battery, but any other suitable power source, including DC and / or AC power sources, can be used. Although not shown, it should be understood that the motor (730), power source (734), and switch (738) can be connected to other circuits, such as microcontrollers, controllers, relays, diodes, capacitors, inductors, resistors, inverters, etc.
[0114] return Figure 19A The container (710) also includes an RFID module (740). As will be described in more detail below, the RFID module (740) is typically configured to respond to one or more corresponding RFID components of the end effector (812). This relationship is generally desired to provide confirmation of the use of the container (710) with a suitable end effector similar to the end effector (810), and confirmation of the proper positioning of the container (710) prior to deployment of the support assemblies (110, 112) via the platform (718).
[0115] As shown in the figure, the RFID module (740) communicates with the switch (738). In this example, the RFID module (740) is configured to trip or otherwise actuate switching between open and closed configurations. It should be understood that this configuration allows the RFID module (740) to activate the motor (730) and thereby expand the platform (718) to deploy the support assemblies (110, 112) only when the RFID module (740) is close to certain corresponding features of the end effector (812).
[0116] In this example, the RFID module (740) is positioned near the proximal end of the compartment (710) close to the opening end (712). Although only a single RFID module (740) is visible, it should be understood that additional RFID modules (740) may be provided on each side of the compartment (710) (e.g., one in...). Figure 19A On the side outside the page, and one in Figure 19A(On one side of the page). As will be described in more detail below, this proximal positioning is generally desirable to confirm the proper positioning of the bin (710) within the end effector (812). In other examples, any suitable number of RFID modules (740) may be used. For example, in some examples, four RFID modules (740) may be used, two on the proximal end of the bin (710) and two on the distal end of the bin (710). Such a configuration may be desirable for providing improved position confirmation. Therefore, in other examples, even more RFID modules (740) may be used, as will be apparent to those skilled in the art given the teachings herein. Additionally, it should be understood that in examples using multiple RFID modules (740), all such RFID modules (470) may communicate with the switch (738) such that all RFID modules (740) may be used to switch the switch (738) between an open-circuit configuration and a closed-circuit configuration.
[0117] like Figure 19A As seen, the cartridge (710) can be used with the end effector (812). Except where otherwise explicitly stated herein, the end effector (812) of this example is substantially similar to the end effector (12) described above. For example, similar to the end effector (12) described above, the end effector (812) of this example employs a firing beam (814) which can be used to cut and suture tissue in a single stroke. Like the firing beam (14) described above, the firing beam (814) of this example can be driven relative to the anvil (818) and the unexploded staple cartridge (837) to cut and suture tissue. Like the staple cartridge (37), the staple cartridge (837) is removably mounted into the channel of the lower jaw (816).
[0118] Unlike the end effector (12) described above, the end effector (812) of this example includes an RFID module (840) positioned adjacent to the fork formed by the anvil (818) and the lower jaw (816). The RFID module (840) of the end effector (812) is typically configured to communicate with the RFID module (740) of the bin (710). By way of example only, the RFID module (840) of the end effector (812) is configured as an RFID sensor or antenna. Meanwhile, the RFID module (740) of the bin (710) is configured as an RFID chip or transmitter for transmitting radio frequency to the RFID module (840) of the end effector (812). Of course, in other examples, this configuration is reversed, and the RFID module (840) may be configured as a chip or transmitter, while the RFID module (740) may be configured as a sensor or antenna.
[0119] Although the end effector (812) in this example is shown as having a single RFID module (840), it should be understood that in other examples, the end effector (812) may include any suitable number of RFID modules (840). For example, in some examples, an array of RFID modules (840) may be used in the end effector (812), wherein a group of RFID modules (840) is configured to be used for certain specific purposes. In such a configuration, one set of RFID modules (840) may be used to detect and authenticate the presence of a specific staple cartridge, such as a staple cartridge (837). Simultaneously, another set of RFID modules (840) may be used to detect and authenticate the presence of a specific support applicator cartridge, such as a support applicator cartridge (710). Yet another set of RFID modules (840) may be used to detect other auxiliary components, such as staple cartridge retainers, and authenticate the presence (or absence) of these other auxiliary components. In some examples, a suitable configuration of the RFID module (840) may be based on at least some of the teachings of the following patent: U.S. Patent Application No. 16 / 458,108, filed June 30, 2019, entitled “Surgical Instrument System Comprising an RFID System,” the disclosure of which is incorporated herein by reference.
[0120] exist Figures 19A to 20B An exemplary use of this example is shown in the figure. As can be seen, the end effector (812) is initially moved relative to the bin (710) to insert the bin (710) into the end effector (812). Figure 20A The switch (738) of the chamber (710) is shown in an open configuration during insertion. This open configuration corresponds to the platform (718) being in a non-expanded configuration. Although not shown, it should be understood that in some applications, the end effector (812) may be electronically locked before and during insertion of the chamber (710). For example, an RFID module (840) may generate a signal corresponding to the absence of a chamber (710). This signal may then communicate with electronic circuitry within the end effector (810) or other parts of the instrument (not shown) to physically or electronically lock parts of the instrument or the end effector (810) to prevent movement (e.g., to prevent the firing beam (814) from advancing distally).
[0121] Once the bin (710) is fully inserted into the end effector (812), the RFID module (740) of the bin (710) is adjacent to the RFID module (840) of the end effector (812), such as Figure 19B As seen in the image. Then, the RFID module (740) responds to the presence of the RFID module (840) by changing the switch (738) from an open configuration to a closed configuration, as... Figure 20BAs shown. This switching of the switch (738) activates the motor (730) and thereby expands the platform (718), which results in the application of the support assembly (110, 112) to the anvil (818) and the staple cartridge (837) of the end effector (812).
[0122] In some applications, the RFID module (840) may also respond to the presence of the RFID module (740). For example, the RFID module (840) may generate one or more signals upon detecting the presence of the RFID module (740). Such signals may then be transmitted to the end effector (812) or other parts of the instrument to release or otherwise disengage certain locking features. Alternatively, such locking features may remain active but may disengage after a predetermined amount of time or until the presence of the RFID module (740) is no longer detected.
[0123] D. An exemplary alternative application device with an external power input
[0124] Figure 21A Another exemplary alternative support applicator compartment (910) (also referred to as a “support applicator”) is shown, which can be used to support, protect, and apply auxiliary materials, such as support assemblies (110, 112), to an end effector. Except where explicitly described herein, the support applicator compartment (810) of this example is substantially similar to the support applicator compartments (210, 410, 510, 710) described above. For example, like compartment (410), compartment (910) of this example includes a housing (916) defining an open end (912) and a closed end (914). Similarly, a platform (918) is inserted between one or more portions of the housing (916).
[0125] Similar to the platform (418) described above, the platform (918) of this example is configured to support a pair of support assemblies (110) on one side of the platform (918) and another pair of support assemblies (112) on the other side of the platform (918). Also similar to the platform (418), the platform (918) of this example is generally configured to expand to apply the support assemblies (110, 112). To support this expandability, the platform (918) includes certain mechanisms generally configured to facilitate its expansion. By way of example only, the platform (918) of this example includes an expandable wedge driven by a linkage mechanism similar to that of the platform (418) described above. However, it should be understood that other suitable mechanisms, such as expandable airbags, spring-loaded wedges, lead screw drives, etc., may be used in other examples. In other examples, the platform (918) may be constructed based on at least some of the teachings of the following patent: U.S. patent application entitled “Apparatus and Method to Apply Buttress to End Effector of Surgical Stapler via DrivenMember” [Attorney’s File No. END9286USNP2], filed on the same date as this application, the disclosure of which is incorporated herein by reference.
[0126] Unlike the platform (418) described above, the scalability of the platform (918) in this example is motor-driven rather than manually operated. Specifically, as Figure 21A As best seen, the chamber (910) includes a power input or key-type actuator (930). The power input (930) is shown communicating with one or more features of the platform (918) to drive the expansion of the platform (918). Such features of the platform (918) can be driven by the power input (930) in a variety of ways. For example, as described above, the platform (918) of this example may use a linkage mechanism to provide its expansion. Thus, in such an example, the power input (930) may be configured to rotate a lead screw or other drive mechanism to move the platform (918) from a flat configuration to an expanded configuration. Of course, in other configurations using alternative expansion mechanisms, the power input (930) may vary as needed. For example, in some examples, the power input (930) may include a vacuum pump, a linear actuator, etc.
[0127] The power input (930) is configured to communicate with certain features of the end effector (1012). As will be described in more detail below, in some examples, the end effector (1012) may include certain power output or rotary drive features that can be used to push, drive, or actuate certain auxiliary components configured for use with the end effector (1012). Therefore, it should be understood that the bin (910) of this example does not require an internal power source for operation. Instead, the bin (910) may be driven by an external power source, including but not limited to certain rotary drive components integrated into the end effector (1012).
[0128] like Figure 21A As seen, the cartridge (910) can be used with the end effector (1012). Except where otherwise explicitly stated herein, the end effector (1012) of this example is substantially similar to the end effector (12) described above. For example, similar to the end effector (12) described above, the end effector (1012) of this example employs a firing beam (1014) which can be used to cut and suture tissue in a single stroke. Like the firing beam (14) described above, the firing beam (1014) of this example can be driven relative to the anvil (1018) and the unexploded staple cartridge (1037) to cut and suture tissue. Like the staple cartridge (37), the staple cartridge (1037) is removably mounted into the channel of the lower jaw (1016).
[0129] Unlike the end effector (12) described above, the end effector (1012) of this example includes a power output or rotary actuator (1040) positioned adjacent to the fork formed by the anvil (1018) and the lower jaw (1016). The power output (1040) of the end effector (1012) is generally configured to engage the power input (930) of the chamber (910) to transmit power from the end effector (1012) to the chamber (910). By way of example only, the power output (1040) of this example is configured to transmit rotary motion to the chamber (910) via the power input (930). Figure 22 As best seen, the power input (930) and the power output (1040) are bonded to each other to facilitate the transmission of this rotational motion.
[0130] Although the power input (930) and power output (1040) of this example are configured for the transmission of mechanical rotational power, it should be understood that in other examples, various forms of energy may be transferred between the power input (930) and the power output (1040). For example, in some examples, the power output (1040) may be configured to transmit translational motion to the power input (930). In other examples, the power output (1040) may be configured to transmit electrical, hydraulic, or pneumatic power to the power input (930). In such examples, the chamber (910) may include other components suitable for using such electrical, hydraulic, or pneumatic power, such as motors, pumps, valves, filters, etc. Of course, in other examples, various alternative power transmission mechanisms may be used, as will be apparent to those skilled in the art given the teachings herein.
[0131] Figure 21A and Figure 21B An exemplary use of a support applicator compartment (910) with an end effector (1012) is shown. Figure 21A As seen, the bin (910) and end effector (1012) are initially separate. In this position, the platform (918) is in a flat configuration. Furthermore, the power input (930) does not communicate with the power output (1040), so the platform (918) cannot be transformed into an expanded configuration. Therefore, when the bin (910) and end effector (1012) are initially separate, the power input (930) and power output (1040) functionally act as locking features to prevent unintentional or premature deployment of the support assemblies (110, 112).
[0132] Next, as Figure 21B As seen, the cartridge is moved into a position within the end effector (1012) by moving the end effector (1012) relative to the cartridge (910) or by moving the cartridge (910) relative to the end effector (1012). In this position, the open end (912) of the cartridge (910) is inserted into the end effector (1012) to allow engagement between the power input (930) and the power output (1040). Once the power input (930) and the power output (1040) are engaged, the platform (918) can expand by rotating the power input (930) via the power output (1040) to deploy the support assemblies (110, 112) onto the anvil (1018) and the staple cartridge (1037). Since the engagement between the power input (930) and the power output (1040) is necessary for the expansion of the platform (918), it should be understood that the power input (930) and the power output (1040) act as alignment features to facilitate the proper placement of the support assemblies (110, 112).
[0133] In some applications, the power output (1040) may be integrated into a driver for other operating components of the firing beam (1014) and / or end effector (1012). In such examples, it should be understood that the power output (1040) may rotate in one direction to drive the firing beam (1014) and / or other operating components of the end effector (1012). Simultaneously, the power output (1040) may rotate in the opposite direction to drive the platform (918) to expand via the power input (930). In some examples, such operating features may be desirable to prevent premature operation of the end effector (1012), such as firing of the firing beam (1014), as during deployment of the support assemblies (110, 112).
[0134] E. An exemplary alternative application device with positioning features
[0135] Figure 23 Another exemplary support applicator compartment (1110) (also referred to as a “support applicator”) is shown, which can be used to support, protect, and apply auxiliary materials, such as support assemblies (110, 112), to an end effector. Except where explicitly described elsewhere herein, the support applicator compartment (1110) of this example is substantially similar to the support applicator compartment (510) described above. For example, like compartment (510), the compartment (1110) of this example includes a platform (1118) configured to expand or otherwise move to apply support assemblies (110, 112) to the end effector. Although not shown, it should be understood that in other examples, the compartment (1110) may also include other additional features similar to a housing.
[0136] Similar to the platform (518) described above, the platform (1118) of this example is configured to support a pair of support assemblies (110) on one side of the platform (1118) and another pair of support assemblies (112) on the other side of the platform (1118). Also similar to the platform (518), the platform (1118) of this example is generally configured to expand to accommodate the support assemblies (110, 112). To support this expandability, the platform (1118) includes an upper support (1120) and a lower support (1122) connected to a hinge (1126). The upper support (1120) includes an elongated, flat surface configured to support the support assemblies (110). Similarly, the lower support (1122) also includes an elongated, flat surface configured to support the support assemblies (112).
[0137] The upper support (1120) is connected to the lower support (1122) at a hinge (1126). The hinge (1126) is positioned at the proximal end of each support (1120, 1122) such that the hinge (1126) is generally configured for insertion into an end effector (12), as will be described in more detail below. The hinge (1126) is generally configured to allow pivoting of the upper support (1120) relative to the lower support (1122).
[0138] Unlike the platform (518) described above, the platform (1118) of this example is configured to be manually expanded by an operator. To facilitate such manual expansion, the platform (1118) of this example also includes an actuating tab (1130) and a locking tab (1132). The actuating tab (1130) extends distally from the upper support (1120) and is generally configured for manual pulling by an operator or for otherwise manipulating the upper support (1120) around the hinge (1126).
[0139] A locking tab (1132) extends distally from the lower support member (1122). As will be described in more detail below, the locking tab (1132) is generally configured to be fastened to the staple cartridge (37) of the end effector (12) to secure the lower support member (1122) to the staple cartridge (37). To facilitate such fastening, the locking tab (1132) is generally shaped to correspond to the distal end of the staple cartridge (37). In addition, the locking tab (1132) includes locking teeth (1134) extending proximally from the distal end of the locking tab (1132). It should be understood that the locking teeth (1134) are generally configured to engage a portion of the staple cartridge (37) to releasably secure the locking tab (1132) to the staple cartridge (37).
[0140] The platform (1118) also includes an upper insert (1140) and a lower insert (1142) extending from the upper support (1120) and the lower support (1122), respectively. As will be described in more detail below, both the upper insert (1140) and the lower insert (1142) are configured to engage portions of the end effector (12) / pig cartridge (37) to provide positioning features or mechanical grounding, thereby ensuring proper positioning of the cartridge (1110) within the end effector (12). The lower support (1122) is also useful for detecting certain features of the end effector (12) (e.g., the wedge slider (41)) to prevent the cartridge (1110) from being used with the end effector (12) in an improper state (e.g., after the wedge slider (41) has been fired).
[0141] The upper insert (1140) extends upward from the upper surface of the upper support (1120). The specific dimensions and shape of the upper insert (1140) are generally configured to allow the upper insert (1140) to be received into the longitudinal anvil slot (42) of the anvil (18). It should be understood that this configuration allows the upper insert (1140) to ensure proper positioning of the upper support (1120) relative to the anvil (18) for proper application of the support assembly (110). In other words, the upper insert (1140) is configured to function similarly to an over-end / under-end gauge to prevent application of the support assembly (110) when the chamber (1110) is misaligned or used entirely with an inappropriate end actuator (12).
[0142] The lower insert (1142) extends downward from the lower support (1122). The specific dimensions and shape of the lower insert (1142) are generally configured to allow it to be received into the vertical slot (49) of the cartridge (37). It should be understood that this configuration allows the lower insert (1142) to ensure proper positioning of the lower support (1122) relative to the cartridge (37). Furthermore, the lower insert (1142) is configured to prevent the use of the cartridge (1110) when the cartridge (37) is in the firing position. It should be understood that this function is generally provided by the lower insert (1142), which is shaped to avoid the wedge slider (41) when it is in its original or unfired position. Meanwhile, the lower insert (1142) is also shaped to contact the wedge slider (41) when the wedge slider (41) is in the firing position, thereby preventing the chamber (1110) from being fully inserted into the end effector (12).
[0143] Figures 24A to 24C An exemplary use of the cartridge (1110) and end effector (12) for applying the support assembly (110, 112) to the end effector (12) / staple cartridge (37) is shown. Figure 24A As seen, the cartridge (1110) can initially be installed onto the cartridge (37) before the cartridge (37) is inserted into the lower jaw (16) of the end effector (12). The cartridge (1110) can be installed onto the cartridge (37) by inserting the lower insert (1142) into the vertical slot (49) of the cartridge (37) and then aligning the locking tab (1132) onto the distal end of the cartridge (37). Incidentally, the step of installing the cartridge (1110) onto the cartridge (37) may also include applying the support assembly (112) to the upper plate (72) of the cartridge (37).
[0144] Although this example application illustrates the attachment of the cartridge (1110) to the cartridge (37) before inserting the cartridge (37) into the lower jaw (16) of the end effector (12), it should be understood that in other applications, the cartridge (37) may be readily inserted into the lower jaw (16) first. In such alternative applications, once the cartridge (37) is inserted into the lower jaw (16), the cartridge (1110) may then be attached to the cartridge (37).
[0145] Regardless of the specific order in which the cartridge (1110) is installed to the staple cartridge (37) and the staple cartridge (37) is installed to the lower jaw (16), once both components are installed, the upper support (1120) of the cartridge (1110) can be used to apply the support assembly (110). Specifically, and as... Figure 24B As is best viewed, the support assembly (110) can be applied by the operator grasping the manipulator (1130) and pivoting the upper support (1120) upward toward the anvil (18) about the hinge (1126). The upper insert (1140) can then be received by the longitudinal anvil slot (42) to ensure proper alignment between the upper support (1120) and the anvil (18). While the upper insert (1140) is received in the longitudinal anvil slot (42), the upper support (1120) can be further pivoted about the hinge (1126) to apply the support assembly (110) to the anvil (18).
[0146] After the support assembly (110) is applied to the anvil (18) as described above, the chamber (1110) can be removed from the end effector (12), as... Figure 24C As shown. In the case of removing the bin (1110), the end effector (12) can then be used in the procedure.
[0147] F. An exemplary alternative application device with a reuse lock
[0148] In some support applicator compartments similar to the support applicator compartment (1110) described above, it may be desirable to include certain features to prevent or hinder the use of the compartment after the support assembly (110, 112) has been applied. Figure 25 An exemplary alternative support applicator compartment (1210) is shown, which is substantially similar to the support applicator compartment (1110) described above, except where otherwise explicitly described herein. For example, like compartment (1110), compartment (1210) of this example includes a platform (1218) having an upper support (1220) and a lower support (1222). Although not shown, it should be understood that the upper support (1220) and lower support (1222) may include structures similar to the actuating tab (1130), locking tab (1132), upper insert (1140), and lower insert (1142).
[0149] The compartment (1210) also includes a hinge (1226) similar to the hinge (1126) described above. However, unlike the hinge (1126), the hinge (1226) in this example includes a one-way stop (1250). The one-way stop (1250) is typically configured to act as a ratchet mechanism by allowing the hinge (1226) to open, while preventing it from fully reclosing after opening. In this example, the one-way stop (1250) is configured as a protrusion or pawl feature integrated into a portion of the hinge (1226) to allow the upper support (1220) to rotate in one direction, but to prevent the upper support (1220) from rotating in another direction after it has passed a predetermined point of rotation.
[0150] Although the one-way stop (1250) is shown in this example as being integrated into the hinge (1226), it should be understood that in other examples, the one-way stop (1250) may be readily integrated into other parts of the compartment (1210). Alternatively, in other examples, the one-way stop (1250) may be a completely separate component attached to one or more elements of the compartment (1210). Various alternative configurations of the one-way stop (1250) will be apparent to those skilled in the art.
[0151] In use, the cartridge (1210) can be used as described above with respect to the cartridge (1110). For example, the cartridge (1210) can first be installed onto the staple cartridge (37). The combination of the cartridge (1210) and the staple cartridge (37) can then be inserted into the lower jaw (16) of the end effector (12). The upper support (1220) can then be pivoted about the hinge relative to the lower support (1222) to apply the support assembly (110). However, unlike the above-described use, it should be understood that once the support (1220) has pivoted past a certain point, a one-way stop (1250) is used to prevent pivoting in the opposite direction. Thus, when the cartridge (1210) is removed after the application of the support assembly (110, 112), the cartridge (1210) can remain in a state that is at least partially open to provide a positive indication of its previous use and thereby prevent its reuse. Although the one-way stop (1250) prevents a certain degree of reverse pivoting of the upper support (1220), it should be understood that at least a certain degree of reverse pivoting is still permitted to allow the bin (1210) to be removed from the end actuator (12) after the application of the support assembly (110, 112).
[0152] G. Exemplary alternative application device with a pad
[0153] In the example, it might be desirable to use the aforementioned support assemblies (110, 112) with pre-applied pads for single use. Such pads might be expected to protect the support assemblies (110, 112) until they are applied to the end effector. Figure 26A As seen herein, the aforementioned support applicator compartment (1110) is shown having an additional pad (1150) disposed on the support assembly (110). Although the pad (1150) is described herein as being used with the compartment (1110), it should be understood that the pad (1150) may alternatively be used with any other compartment (210, 410, 510, 710, 810, 1210) described herein.
[0154] The pad (1150) in this example is a single-material cover configured to cover the support assembly (110). In this example, the pad (1150) comprises a paper or polymer material. In other examples, various alternative materials may be used. Additionally, or alternatively, such material of the pad (1150) may be coated with one or more coatings of various materials, such as wax, polymer, alloy, combination of different materials, etc.
[0155] The pad (1150) includes a covering portion (1152) and a redundant portion (1144). The covering portion (1152) corresponds to the size and shape of the support assembly (110) to cover the support assembly (110). Meanwhile, the redundant portion (1144) extends proximally from the support assembly (110). As will be described in more detail below, the redundant portion (1144) is generally configured to engage a portion of the end actuator (12) to provide a visual cue for removing the pad (1150).
[0156] Figure 26A and Figure 26B Exemplary uses of the compartment (1110) and the liner (1150) are shown. It should be understood that, except where explicitly described elsewhere herein, the use of the compartment (1110) with the liner (1150) is substantially similar to that described above relative to... Figures 24A to 24C The intended use. For example, as described above, the cartridge (1110) can first be installed onto the staple cartridge (37), and then both the cartridge (1110) and the staple cartridge (37) can be inserted into the lower jaw (16) of the end effector (12). However, unlike the intended use described above, in this intended use, a liner (1150) is pre-applied to the cartridge (1110) such that the liner (1150) is also inserted into the lower jaw (16) along with the cartridge (1110) and the staple cartridge (37), as... Figure 26A As seen in the text.
[0157] When the jaw (1110) is inserted into the lower jaw (16), the excess portion (1144) engages with the fork of the end effector (12) formed at the intersection of the lower jaw (16) and the anvil (18). This engagement causes the excess portion (1144) of the liner (1150) to be compressed, rolled, or clumped in the space between the fork of the end effector (12) and the support assembly (110). This change in the excess portion (1144) provides a visual cue to the operator to remind them to remove the liner (1150) before proceeding. Although not shown, it should be understood that in some examples, such functionality of the excess portion (1144) can be increased by including a proximal end that is T-shaped or otherwise expanded to avoid the possibility that the excess portion (1144) will remain longitudinally extended due to its entry into the end effector (12).
[0158] Next, the pad (1150) can be removed by the operator aspirating the excess portion (1144) or by other parts of the pad (1150) configured to assist in removal (e.g., removing the tabs). Once the pad (1150) has been removed, it can be removed by the operator as described above regarding... Figure 24B The similar suction manipulator (1130) and pivoting of the upper support (1120) are used to apply the support assembly (110) to the anvil (18). The chamber (1110) can then be removed, and the end effector (12) can be readily used in surgical procedures.
