[0061] Many specific details are listed herein to provide a thorough understanding of the overall structure, function, manufacture, and use of the embodiments described in the specification and shown in the drawings. Well-known operations, parts, and elements are not described in detail to avoid obscuring the embodiments described in the specification. The reader will understand that the embodiments described and shown herein are non-limiting examples, so that it can be recognized that the specific structural and functional details disclosed herein can be representative and illustrative. These embodiments can be modified and changed without departing from the scope of the claims.

[0062] The terms "proximal" and "distal" are used herein relative to a clinician manipulating the handle portion of a surgical instrument. The term "proximal" refers to the portion closest to the clinician, and the term "distal" refers to the portion positioned away from the clinician. It should also be understood that for brevity and clarity, spatial terms such as "vertical," "horizontal," "upper," and "lower" may be used herein in conjunction with the accompanying drawings. However, surgical instruments are used in many orientations and positions, and these terms are not intended to be limiting and / or absolute.

[0063] Various exemplary devices and methods are provided for performing laparoscopic and minimally invasive surgical procedures. However, the reader will readily appreciate that the various methods and devices disclosed herein can be used in a variety of surgical procedures and applications, including, for example, in conjunction with open surgical procedures. Continuing to refer to this detailed description, the reader will further appreciate that the various instruments disclosed herein can be inserted into the body in any manner, such as through a natural cavity, through an incision or puncture formed in the tissue, etc. The working portion or end effector portion of the instrument can be inserted directly into the patient's body or can be inserted through an access device having a working channel through which the end effector and elongated shaft of the surgical instrument can be advanced.

[0064] See also Figure 1 , the surgical stapling system 100000 includes a shaft 100002 and an end effector 100004 extending from the shaft 100002. The end effector 100004 includes a first jaw 100006 and a second jaw 100008. The first jaw 100006 includes an elongated channel 100007 and a staple cartridge 100010. The staple cartridge 100010 is configured to be replaceable during a surgical procedure. The staple cartridge 100010 includes tabs 100011 on its lateral sides that fit into corresponding recesses 100009 defined in the elongated channel 100007 and align the staple cartridge 100010 in the channel 100007. The staple cartridge 100010 includes one or more locking shoulders that releasably engage the elongated channel 100007 and allow the staple cartridge 100010 to be removed from the channel 100007. Alternatively, the staple cartridge 100010 may not be removable from the first jaw 100006 or at least not easily replaceable from the first jaw.

[0065] The second jaw 100008 includes an anvil configured to deform the nail ejected from the nail magazine 100010. The second jaw 100008 is capable of being moved in an open position ( Figure 5 ) and closed position ( Figure 4 ) between the first jaw 100006 and the second jaw 100008; however, the first jaw 100006 is capable of pivoting relative to the second jaw 100008. The surgical stapling system 100000 also includes an articulation joint 100013, which is configured to allow the end effector 100004 to rotate or articulate relative to the axis 100002. However, the surgical stapling system 1000000 may not include an articulation joint.

[0066] The staple cartridge 100010 includes a cartridge body 100012. The cartridge body 100012 includes: a proximal end 100014; a distal end 100016; and a platform 100018 extending between the proximal end 100014 and the distal end 100016. In use, the staple cartridge 100010 is positioned on a first side of the tissue to be stapled and the anvil 100008 is positioned on a second side of the tissue. The anvil 100008 moves toward the staple cartridge 100010 (see Figure 4 and Figure 5 ) to compress and clamp the tissue against the platform 100018. Then, the nails 100021 removably stored in the magazine body 100012 can be deployed into the tissue. The magazine body 100012 includes nail cavities 100020 defined therein, wherein the nails are removably stored in the nail cavities 100020. The nail cavities 100020 are arranged in six longitudinal rows. Three rows of nail cavities are positioned on the first side of the longitudinal slot 100022, and three rows of nail cavities are positioned on the second side of the longitudinal slot 100022. Other arrangements of nail cavities and nails are also possible.

[0067] The nails are supported in the cartridge body 100012 by the nail drivers. The nails supported on the nail drivers can be found in U.S. Patent Application Publication No. 2021 / 0059672, entitled "SURGICAL INSTRUMENT WITH WIRELESS COMMUNICATION BETWEEN A CONTROL UNIT OF AROBOTIC SYSTEM AND REMOTE SENSOR", which is hereby incorporated by reference in its entirety. The driver is movable between a first or unfired position and a second or fired position to eject the nail from the nail cavity 100020. The driver is retained in the cartridge body 100012 by a retainer or disc 100024, which extends at least partially around the bottom of the cartridge body 100012 and includes a resilient member configured to grip the cartridge body 100012 and retain the retainer 100024 to the cartridge body 100012. Alternatively, there may be no retainer or disc attached to the cartridge body 100012. The drive can be driven by a sliding member 100026 (see Figure 2 and Figure 6 ) between its unfired position and its fired position. Sliding member 100026 is movable between a proximal position adjacent to proximal end 100014 and a distal position adjacent to distal end 100016. Sliding member 100026 includes a plurality of ramp surfaces configured to slide under the driver and lift the driver toward anvil 100008, and the nail is supported thereon. The nail may not be supported by the nail driver, but the nail includes an integral driving surface that is directly engaged by the sliding member 100026 to lift the nail, and examples of these driving surfaces are described in U.S. Patent Application Publication No. 2015 / 0173756 entitled "SURGICAL CUTTING AND STAPLING METHODS", which is hereby incorporated by reference in its entirety.

[0068] In addition to the above, the slide 100026 is moved distally by a firing actuator 100027, which includes a firing driver 100028 and a firing rod extending proximally from the firing driver 100028. The firing driver 100028 is configured to contact the slide 100026 and push the slide 100026 toward the distal end 100016. The firing rod includes a plurality of laminated strips; however, the firing rod may include, for example, a rod. The longitudinal slot 100022 defined in the cartridge body 100012 is configured to receive the firing driver 100028 and the firing rod. The anvil 100008 also includes a slot defined therein for receiving the firing driver 100028. The firing drive 100028 also includes a first cam 100030 that engages the first jaw 100006 in the slot of the anvil 100008 and a second cam 100032 that engages the second jaw 100008. As the firing drive 100028 is advanced distally, the first cam 100030 and the second cam 100032 control the distance or tissue gap between the platform 100018 of the staple cartridge 100010 and the anvil 100008. The firing drive 100028 also includes a knife 100034 that is configured to cut into tissue captured between the staple cartridge 100010 and the anvil 100008. It is desirable that the knife 100034 is positioned at least partially proximate to the ramp surface of the sliding member 100026 so that the staples are ejected prior to the knife 100034. Additionally, the firing drive 100028 includes a first notch 100036 defined on a first lateral side thereof and a second notch 100038 defined on a second lateral side thereof.

[0069] The anvil 100008 can be moved from the open position to the closed position using a closure system that is controlled separately from the firing drive 100028. The firing drive is part of a firing actuator that is separate from the closure system and can be operated distinctly. The anvil 100008 can include a ramp on its proximal end, and the closure system includes a closure tube that can move distally to engage the ramp and cam the anvil 100008 to the closed position. In the closed position, the first cam 100030 and the second cam 100032 of the firing drive 100028 translate distally and hold the anvil 100008 in the closed position. In order to convert the anvil 100008 to the open position, the closure tube can be retracted proximally, and a spring positioned within the end effector 100004 can bias the anvil 100008 to the open position. The anvil 100008 may include a tab, and the closure tube may define an aperture that engages the tab when the closure tube is moved proximally, thereby actively transitioning the anvil 100008 to the open position. Exemplary closure systems and closure tubes are described in U.S. Patent Application Publication No. 2021 / 0059672, which was previously incorporated herein by reference in its entirety.

[0070] The anvil 100008 can be moved from an open position to a closed position using a firing driver 100028. Thus, the anvil 100008 can include a ramp extending proximally from a slot defined therein, which is engaged by the firing driver 100028 during the first portion of the stroke of the firing driver 100028 to move the anvil 100008 to a closed position. The first portion of the stroke of the firing driver can be, for example, about 0.100 "-0.250" of the stroke of the firing driver 100028. After the first portion of the stroke is completed, the firing driver 100028 can be advanced distally through the second portion of the stroke to deploy nails from the nail magazine 100010 and cut into the tissue captured by the end effector, as described above. The firing driver for closing the anvil and firing the nails is described in U.S. Patent No. 11,160,551. The firing driver 100028 can be driven distally by a drive beam extending therefrom. Thus, the drive beam may include a plurality of laminated strips.The firing drive 100028 may be driven distally by an upper drive rod attached at the upper end of the firing drive 100028 and a lower drive rod attached to the lower end of the firing drive 100028, examples of which may be found in U.S. Patent Application Publication No. 2015 / 0173756, which is hereby incorporated by reference in its entirety.

[0071] After the nail magazine 100010 has been fired or at least partially fired, if necessary, the nail magazine can be removed from the elongated channel 100007 and then replaced with another replaceable nail magazine. At this time, the surgical suturing system 100000 can be reused during surgery to continue suturing and cutting into patient tissue. However, the previously fired nail magazine can be accidentally loaded into the elongated channel 100007. If the firing driver 100028 will be advanced distally in such previously fired nail magazine, the surgical suturing system 100000 can cut patient tissue without suturing patient tissue. If the firing driver 100028 is advanced distally to complete the nail firing stroke without the nail magazine being positioned in the elongated channel 100007 at all, the surgical suturing system 100000 can similarly cut patient tissue without suturing patient tissue. In addition, various surgical nail magazines can have different arrays and / or orientations of nails / fasteners therein. The size of the nails or fasteners and the number of fasteners can vary, for example, depending on the type of magazine. In order to ensure that the nails are correctly crimped or formed, usually, the surgical nail magazine is matched with a corresponding compatible anvil having an appropriate array of nail forming pits and appropriate cutting and firing components. If an "incompatible" magazine is loaded into a surgical stapling device with an anvil that does not match the nail magazine, the nails may not be correctly formed during the firing process.

[0072] In view of the above, the surgical stapling system 100000 includes a lockout system 100100 configured to prevent distal movement of the firing drive 100028 unless a compatible and unused staple cartridge is positioned in the first jaw 100006. The lockout system 100100 includes a first lockout 100102 including a first wedge 100104 and a first spring 100106 that biases the first wedge 100104 into a first recess 100036 of the firing drive 100028. The first spring 100106 is mounted on a first lateral side 100108 thereof to the elongated channel 100007 of the first jaw 100006; however, the first spring 100106 may be mounted in any suitable location. The lockout system 100100 also includes a second lockout 100112, which includes a second wedge 100114 and a second spring 100116 that biases the second wedge 100114 into the second recess 100038 of the firing drive 100028. The second spring 100116 is mounted to the elongated channel 100007 of the first jaw 100006 on its second lateral side 100118; however, the second spring 100116 can be mounted in any suitable position. The first lockout 100102 and the second lockout 100112 can be mounted to the shaft 100002. In addition, the springs 100106 and 100116 include coil springs, but may include any suitable biasing member.

[0073] In use, the lockout system 100100 prevents advancement of the firing drive 100028 unless a compatible and unused staple cartridge is positioned in the first jaw 100006. The staple cartridge 100010 includes two discrete authentication keys, namely a first authentication key 100120 and a second authentication key 100130, the first authentication key being configured to move the first lockout member 100102 from a locked state (a state in which the first wedge member 100104 is positioned in the first recess 100036 of the firing drive 100028, see Figure 6 and Figure 7 ) is transformed to an unlocked state (a state in which the first wedge 100104 is displaced (i.e., “released”) from the first recess 100036 by the first authentication key 100120, see Figure 8 ), the second authentication key is configured to be able to move the second locking member 100112 from a locked state (a state in which the second wedge 100114 is positioned in the second recess 100038 of the firing drive 100028, see Figure 6 and Figure 7 ) is transformed to an unlocked state (a state in which the second wedge 100114 is displaced (i.e., “released”) from the second recess 100038 by the second authentication key 100130, see Figure 8 ).

[0074] The lockouts 100102, 100112 are designed so that a single lockout by itself can prevent the firing drive 100028 from moving distally through the staple cartridge 100010. The spring and wedge of each lockout 100102, 100112 are selected so that the lockout can resist the force transmitted through the firing drive 100028 and prevent the firing drive 100028 from being further advanced distally. As described in more detail below, the lockout system 100100 ensures that the staple cartridge positioned in the first jaw 100006 is compatible with the stapling instrument 100000 and is in an unused state so as to allow the firing drive 100028 to move through the firing stroke.

[0075] like Figure 6 As shown, the staple cartridge 100010 includes a first key 100120 extending from the proximal end 100014 of the cartridge body 100012. When the staple cartridge 100010 is inserted into the first jaw 100006, the first key 100120 engages the first cam surface 100107 of the first wedge 100104. When the staple cartridge 100010 is positioned in the elongated channel 100007, the first key 100120 cams the first wedge 100104 away from the first notch 100036, thereby releasing the first lockout 100102 and placing the first lockout 100102 in an unlocked state.

[0076] The first lockout 100102 can be a compatible staple cartridge lockout because a compatible staple cartridge having a sufficient authentication key, such as the first key 100120 on the cartridge body 100012, transitions the first lockout 100102 to the unlocked position, while a staple cartridge without the first key 100120 or the sufficient authentication key does not transition to the unlocked position. The first key 100120 or the sufficient authentication key can be located on another portion of the staple cartridge, such as the retainer 100024.

[0077] In addition to the above, the nail magazine 100010 includes a second key 100130 extending from the proximal end of the sliding member 100026. It is worth noting that Figure 6 As shown, the slider 100026 is positioned in the proximal unfired position, thereby indicating that the nail magazine 100010 is an unused nail magazine (i.e., no nails in the nail magazine have been deployed therefrom). When the nail magazine 100010 is inserted into the first jaw 100006, the second key 100130 engages the second cam surface 100117 of the second wedge 100114. When the nail magazine 100010 is placed in the elongated channel 100007, the second key 100130 cams the second wedge 100114 away from the second recess 100038, thereby releasing the second lockout 100112 and placing the second lockout 100112 in an unlocked state.

[0078] The second lockout 100112 can be a spent cartridge lockout because a cartridge having a slider with a sufficient key in a sufficient position will transition the second lockout to an unlocked position, while a cartridge without a slider with a sufficient key in a sufficient position will not transition to an unlocked position. If the clinician inadvertently positions a spent (i.e., all of the nails have been deployed from the cartridge) or a partially spent (i.e., some but not all of the nails have been deployed from the cartridge) cartridge 100010 in the first jaw 100006, the second key 100130 will not be able to engage the second wedge 100114 and cam the second wedge out of the second notch 100038, thereby preventing the firing driver 100028 from being advanced distally through the cartridge even if the cartridge 100010 were to unlock the first lockout 100102 with the first key 100120. The second key 100130 can extend a certain length from the slider 100026 so that if the slider 100026 is in its most proximal position or a position close enough to the most proximal position, the second key 100130 can only transform the second lockout 100112 to the unlocked position. The slider 100026 is in a position close enough to the most proximal position, where no nails have been fired from the nail magazine 100010, but the slider 100026 has moved less than a threshold amount from the most proximal position. In either such position, the slider 100026 is in a proximal unfired position, and when the nail magazine 100010 is seated in the first jaw 100006, the second key 100130 will unlock the second lockout 100112. However, if the slider 100026 has moved distally beyond the threshold distance when the staple cartridge 100010 is seated in the first jaw 100006, the staple cartridge 100010 will not be able to transition the second lockout 100112 to the unlocked position, and therefore, the staple cartridge will need to be replaced with an unused (and compatible) staple cartridge in order to fire the stapling instrument 100000. The second key 100130 may be positioned on another portion of the staple cartridge 100010 that indicates the firing state of the staple cartridge 100010 (unused, used, partially used), such as a cover removably positioned on the deck 100018 of the staple cartridge 100010.

[0079] Figure 7 and Figure 8The staple cartridge 100010 is shown inserted into the first jaw 100006 of the end effector 100004. Notably, the first authentication key 100120 engages the first cam surface 100107 of the first wedge 100104 to drive the first wedge 100104 out of the first recess 100036 and transition the first lockout 100102 to the unlocked state. Similarly, the second authentication key 100130 engages the second cam surface 100117 of the second wedge 100114 to drive the second wedge 100114 out of the second recess 100038 and transition the second lockout 100112 to the unlocked state. With both the first and second lockouts 100102 , 100112 in their respective unlocked states, the firing drive 100028 is free to translate through the longitudinal slot 100022 to deploy staples from the staple cartridge 100010 and incise tissue captured by the end effector 100004 .

[0080] See now Fig. 9 , the nail magazine 100010 has been replaced by a first replacement nail magazine 100140, which includes a first key 100120 extending therefrom, but does not include a second key. The absence of the second key may indicate, for example, a nail magazine that does not have a compatible slider even if the slider is in a proximal unused position, or alternatively, a slider with a sufficient second key that is not in an unfired position (i.e., a compatible slider is in a partially used or used position). Therefore, when the first nail magazine 100140 is removably positioned in the first jaw 100006, the first lockout 100102 is transformed to an unlocked state (via the first key 100120), but the second lockout 100112 remains in a locked state. In this state, the lockout system 100100 prevents distal movement of the firing drive 100028. More specifically, in this state, as the firing drive 100028 moves distally, the second wedge 100114 edges the trailing edge of the second recess 100038 , thereby preventing distal movement of the firing drive 100028 .

[0081] See now Fig.10, the nail magazine 100010 has been replaced by a second replacement nail magazine 100142, which includes a second key 100130 extending therefrom, but does not include a first key. The absence of the first key in the second replacement nail magazine 100142 may indicate that the second replacement nail magazine 100142 is an incompatible nail magazine. Therefore, when the second replacement nail magazine 100142 is placed in the first jaw 100006, the second lockout member 100112 is transformed into an unlocked state (via the second key 100130), but the first lockout member 100102 remains in the locked state. In this state, the lockout system 100100 prevents the distal movement of the firing driver 100028. More specifically, in this state, as the firing driver 100028 moves distally, the first wedge 100104 edges the trailing edge of the first recess 100036, thereby preventing the distal movement of the firing driver 100028.

[0082] Thus, the aforementioned lockout system 100100 provides a "two-factor" authentication lockout that communicates to the clinician not only that the staple cartridge positioned in the first jaw 100006 is a compatible staple cartridge, but also that the staple cartridge is ready to fire (i.e., unused). This eliminates the possibility that a compatible staple cartridge that has been used or at least partially used is positioned in the first jaw 100006 of the end effector 100004. In addition, as described above, the lockout system 100100 includes two lockouts 100102, 100112, each of which is used to constrain the same drive system, the firing drive 100028. The firing drive 100028 is prevented from moving through the staple cartridge to both position the jaws of the end effector 100004 relative to each other and drive the staples from the staple cartridge unless both the lockouts 100102, 100112 are transitioned to their respective unlocked states via the authentication key.

[0083] See now Fig.11 According to the present disclosure, a firing drive 100220 for use with a locking system 100100 is provided. The firing drive 100220 is similar in many respects to the firing drive 100028, with some differences described below. The firing drive 100220 can be used to replace the firing drive 100028 in the firing actuator 100027.

[0084] Similar to the firing drive 100028, the firing drive 100220 includes a first recess 100222 defined on a first lateral side thereof. The first recess 100222 includes a first leading edge 100227 at a first longitudinal distance from a distal end 100221 of the firing drive 100220, a first trailing edge 100223 at a second longitudinal distance from the distal end 100221 of the firing drive 100220, and a first sidewall 100231 extending between the first leading edge 100227 and the first trailing edge 100223. The distance between the first leading edge 100227 and the first trailing edge 100223 (i.e., the length of the first sidewall 100231) defines the width of the first recess 100222.

[0085] In addition, the firing drive 100220 includes a second recess 100224 defined on a second lateral side thereof. The second recess 100224 includes a second leading edge 100229 at a third longitudinal distance from the distal end 100221 of the firing drive 100220, a second trailing edge 100225 at a fourth longitudinal distance from the distal end 100221 of the firing drive 100220, and a second sidewall 100233 extending between the second leading edge 100229 and the second trailing edge 100225. The distance between the second leading edge 100229 and the second trailing edge 100225 (i.e., the length of the second sidewall 100233) defines the width of the second recess 100254.

[0086] like Fig.11 As shown, the width of the second recess 100224 is the same as the width of the first recess 100222; however, the widths may be different, as will be described in more detail elsewhere herein. The second leading edge 100229 and the first leading edge 100227 can be located at different longitudinal distances from the distal end 100221 of the firing drive 100220; however, the leading edges 100227, 100229 can be located at the same distance from the distal end 100221 of the firing drive 100220. In addition, as Fig.11 As shown, the second trailing edge 100225 and the first trailing edge 100223 are at different longitudinal distances from the distal end 100221 of the firing drive 100220; however, the longitudinal distances may be the same. For example, the first notch 100036 may include a first trailing edge (similar to the first trailing edge 100223), and the second notch 100038 may include a second trailing edge (similar to the second trailing edge 100225), and both trailing edges are at the same distance from the distal end of the firing drive 100028. Therefore, if a user attempts to drive the firing drive through a firing stroke without a compatible, unused staple cartridge positioned in the end effector, the trailing edges can cooperatively apply resistance to the firing drive.

[0087] The firing drive 100220 can be used with the end effector 100004 to move the anvil 100008 from an open position ( Figure 5 ) moves to the closed position ( Figure 4 ), and then firing the nail from the nail magazine 100010. As described above, an exemplary firing drive that closes the end actuator and then fires the nail from the nail magazine is described in U.S. Patent No. 11,160,551, entitled "ARTICULATABLE SURGICAL STAPLING INSTRUMENTS", which is incorporated herein by reference in its entirety.

[0088] In operation, the firing drive 100220 is driven through a first motion and a second motion, the second motion being distal to and subsequent to the first motion. During the first motion, the firing drive 100220 engages a ramp on the second jaw 100008 of the end effector 100004 to move the second jaw 100008 from an open position ( Figure 5 ) moves to the closed position ( Figure 4 ). The first movement of the firing driver 100220 can be, for example, approximately 0.100"-0.250" of the travel of the firing driver 100220. After the first movement and during a second movement distal to the first movement, the firing driver 100220 drives the sled 100026 through the staple cartridge 100010 to deploy staples therefrom. The second movement of the firing driver 100220 can be the remaining portion of the travel of the firing driver 100220 after the first movement.

[0089] like Fig.11 As shown and described above, the firing drive 100220 includes two longitudinally offset notches 100222, 100224. Fig.11 , the firing drive 100220 is in the proximal position. In the proximal position, the first notch 100222 receives the first wedge 100104, which corresponds to the first lockout 100102 being in the locked state. Additionally, in the proximal position, the second wedge 100114 engages the side wall 100235 of the firing drive 100220, thereby maintaining the second lockout 100112 in the unlocked state. As described elsewhere herein, each of the lockouts 100102, 100112 is designed such that the firing drive 100220 cannot travel distally as long as one of the lockouts is in its locked state. Thus, as Fig.11 As shown, when the first lockout 100102 is in its locked state, the firing driver 100220 cannot travel distally. Specifically, the first wedge 100104 of the first lockout 100102 engages the first rear edge 100223 of the first notch 100222, thereby preventing the distal movement of the firing driver 100220.

[0090] When a compatible and unused staple cartridge (such as staple cartridge 100010) is inserted into first jaw 100006 (such as Fig.12 As shown in FIG. 1 , the first authentication key 100120 engages the first wedge 100104 and causes its cam to move away from the first notch 100222, thereby transforming the first lockout member 100102 to an unlocked state. In addition, the second authentication key 100130 engages the second wedge 100114 to maintain the second lockout member 100112 in the unlocked state. Thus, the firing drive 100220 is able to move distally to move the anvil 100008 to the closed position and fire the nail from the nail magazine 100010, as shown in FIG. Fig.13 shown.

[0091] See now Fig.14 , when an incompatible staple cartridge (such as staple cartridge 100142) is inserted into first jaw 100006, second authentication key 100130 engages second wedge 100114 to maintain second lockout 100112 in a locked state. However, it is noteworthy that first staple cartridge 100142 does not include first authentication key 100120, and therefore first lockout 100102 remains in a locked position, thereby preventing distal movement of firing driver 100220. Specifically, first wedge 100104 of first lockout 100102 engages first rear edge 100223 of notch 100222, thereby preventing distal movement of firing driver 100220.

[0092] See now Fig.15 and Fig.16 , when an incompatible staple cartridge (such as staple cartridge 100140) is inserted into the first jaw 100006, the first authentication key 100120 engages the first wedge 100104 and cams it away from the first notch 100222, thereby transforming the first lockout 100102 to an unlocked state. However, it is worth noting that the staple cartridge 100140 does not include a second authentication key 100130 that engages the second lockout 100112 and holds it in the unlocked position. However, as described above, the second wedge 100114 engages the side wall 100235 of the firing driver 100220, which holds the second lockout 100112 in the unlocked state. Therefore, the firing driver 100220 is able to translate distally through the first portion of its firing stroke.

[0093] The first stroke portion may include the above-described first motion, wherein the firing drive 100220 engages a ramp on the second jaw 100008 of the end effector 100004 to move the anvil 100008 from the open position ( Figure 5 ) moves to the closed position ( Figure 4). The first stroke portion may include, for example, approximately 0.100"-0.250" of the stroke of the firing driver 100220. The first stroke portion may be defined as the distance until the second wedge 100114 engages the second trailing edge 100225 of the second recess 100224, as described in more detail below. During the first stroke portion, the second wedge 100114 of the second lockout 100112 travels along the side wall 100235 of the firing driver 100220, and the first wedge 100104 of the first lockout 100102 moves along the other side wall 100237 of the firing driver 100220. During the first movement, the wedge 10114 applies friction to the side wall 100235 of the firing driver 100220; however, the friction is not sufficient to prevent distal movement of the firing driver 100220.

[0094] Once the firing drive 100220 has been translated distally through the first stroke portion, as Fig.16 As shown, the second wedge 100114 becomes aligned with the second notch 100224. Since the nail cartridge 100140 does not include the second authentication key 100130 that engages the second lockout 100112 and holds it in the unlocked state, the second spring 100116 biases the second wedge 100114 into the second notch 100224, thereby preventing further distal movement of the firing driver 100220. Specifically, the second wedge 100114 of the second lockout 100112 engages the second rear edge 100225 of the second notch 100224, thereby preventing distal movement of the firing driver 100220.

[0095] Thus, using the firing drive 100220 with the lockout system 100100 enables the clinician to lock the end effector 100004 in the open state ( Figure 5 ) and closed state ( Figure 4 ) to grasp tissue, for example, when a staple cartridge having a first authentication key 100120 is positioned in the end effector. For example, such a staple cartridge may include a spent staple cartridge 100010. However, since there is not a sufficient second authentication key, the firing drive 100220 is prevented from being further advanced through the staple cartridge. The firing drive 100220 allows the staple cartridge including the first authentication key 100120 to maintain some functionality (i.e., thereby allowing the end effector 100004 to be opened and closed), but prevents the firing drive 100220 from advancing through a portion of its stroke, which may result in damage to patient tissue (moving the knife through a staple cartridge that may not include staples therein).

[0096] In addition, the inclusion of the second cam surface 100117 on the second wedge 100114 enables the clinician to move the firing driver 100220 proximally after the second lockout 100112 has transitioned to the locked state (i.e., when the second wedge 100114 is positioned in the second recess 100224). Specifically, as the firing driver 100220 moves proximally, the second cam surface 100117 engages the second leading edge 100229 of the second recess 100224, which cams the second wedge 100114 away from the second recess 100224 and reengages the second wedge 100114 with the sidewall 100235.

[0097] See now Fig.17 According to the present disclosure, a firing drive 100250 for use with a locking system 100100 is provided. The firing drive 100250 is similar in many respects to the firing drive 100028 and the firing drive 100220, with some differences described below. The firing drive 100250 can be used to replace the firing drive 100028 or the firing drive 100250 in the firing actuator 100027.

[0098] Similar to the firing drive 100028 and the firing drive 100220, the firing drive 100220 includes a first recess 100252 defined on a first lateral side thereof. The first recess 100252 includes a first leading edge 100257 at a first longitudinal distance from the distal end 100251 of the firing drive 100250, a first trailing edge 100253 at a second longitudinal distance from the distal end 100251 of the firing drive 100250, and a first sidewall 100261 extending between the first leading edge 100257 and the first trailing edge 100253. The distance between the first leading edge 100257 and the first trailing edge 100253 (i.e., the length of the first sidewall 100261) defines the width of the first recess 100252.

[0099] In addition, the firing drive 100220 includes a second recess 100254 defined on a second lateral side thereof. The second recess 100254 includes a second leading edge 100259 at a third longitudinal distance from the distal end 100251 of the firing drive 100250, a second trailing edge 100255 at a fourth longitudinal distance from the distal end 100251 of the firing drive 100250, and a second sidewall 100263 extending between the second leading edge 100259 and the second trailing edge 100255. The distance between the second leading edge 100259 and the second trailing edge 100255 (i.e., the length of the second sidewall 100263) defines the width of the second recess 100254.

[0100] like Fig.1720. As shown, the width of the second recess 100254 is different from the width of the first recess 100252. Specifically, the width of the second recess 100254 is greater than the width of the first recess 100252. The second leading edge 100259 and the first leading edge 100257 can be located at the same longitudinal distance from the distal end 100251 of the firing drive 100250; however, the leading edges 100257, 100259 can be located at different distances from the distal end 100251 of the firing drive 100250. The second trailing edge 100255 can be located at a longitudinal distance from the distal end 100251 of the firing drive 100250 that is greater than the longitudinal distance of the first trailing edge 100253 from the distal end 100251 of the firing drive 100250.

[0101] The firing drive 100250 can be used with the end effector 100004 to move the anvil 100008 from an open position ( Figure 5 ) moves to the closed position ( Figure 4 ), and then firing the nail from the nail magazine 100010. As described above, the firing drive of the closing end actuator and then firing the nail from the nail magazine is described in U.S. Patent No. 11,160,551, which is incorporated herein by reference in its entirety.

[0102] In operation, the firing drive 100250 is driven through a first motion and a second motion, the second motion being distal to and subsequent to the first motion. During the first motion, the firing drive 100250 engages a ramp on the second jaw 100008 of the end effector 100004 to move the second jaw 100008 from an open position ( Figure 5 ) moves to the closed position ( Figure 4 ). The first movement of the firing driver 100250 can be, for example, approximately 0.100"-0.250" of the travel of the firing driver 100220. After the first movement and during a second movement distal to the first movement, the firing driver 100250 drives the sled 100026 through the staple cartridge 100010 to deploy staples therefrom. The second movement of the firing driver 100250 can be the remaining portion of the travel of the firing driver 100250 after the first movement.

[0103] As described above, the firing drive 100250 includes two notches having different widths, namely notches 100252 and 100254. Fig.17As shown, the firing drive 100250 is in a proximal position. In the proximal position, the first notch 100252 receives the first wedge 100104, which corresponds to the first lockout 100102 being in a locked state. In addition, the second notch 100254 receives the second wedge 100114, which corresponds to the second lockout 100112 being in a locked state. The firing drive 100250 is capable of translating with one of the lockouts in a locked state, as described in more detail below.

[0104] When a compatible and unused staple cartridge (such as staple cartridge 100010) is inserted into first jaw 100006 (such as Fig.18 100252), the first authentication key 100120 engages the first wedge 100104 and causes its cam to move away from the first notch 100252, thereby transforming the first lock 100102 to an unlocked state. In addition, the second authentication key 100130 engages the second wedge 100114 and causes its cam to move away from the second notch 100254, thereby transforming the second lock 100112 to an unlocked state. Thus, the firing drive 100250 is able to move distally to move the anvil 100008 to a closed position and fire the nails from the nail magazine 100010, as shown. Fig.19 shown.

[0105] See now Fig. 20 , when an incompatible staple cartridge (such as staple cartridge 100142) is inserted into the first jaw 100006, the second authentication key 100130 engages the second wedge 100114 and cams it away from the second notch 100254, thereby transforming the second lockout 100112 to an unlocked state. However, it is worth noting that the first staple cartridge 100142 does not include the first authentication key 100120, and therefore the first lockout 100102 remains in the locked position, thereby preventing distal movement of the firing driver 100250. Specifically, the first wedge 100104 of the first lockout 100102 engages the first trailing edge 100253 of the first notch 100252, thereby preventing distal movement of the firing driver 100250.

[0106] See now Fig.21 and Fig. 22 , when an incompatible staple cartridge (such as staple cartridge 100140) is inserted into first jaw 100006, first authentication key 100120 engages first wedge 100104 and cams it away from first notch 100252, thereby transitioning first closure member 100102 to an unlocked state. However, it is worth noting that staple cartridge 100140 does not include second authentication key 100130 that engages second closure member 100112 and cams it to an unlocked position. Fig.2114, the second trailing edge 100255 of the second notch 100254 is positioned proximally relative to the second wedge 100114, and thus the second trailing edge 100255 cannot impede the movement of the firing drive 100250. Thus, the firing drive 100250 is able to translate distally through the first portion of its stroke even though the second lockout 100112 is still in the locked state. During the first portion of the stroke, the wedge 10114 applies a friction force to the second sidewall 100263 of the firing drive 100250; however, the friction force is insufficient to impede the distal movement of the firing drive 100250.

[0107] As further described above, the first stroke portion includes the above-mentioned first movement, in which the firing drive 100250 engages the ramp on the second jaw 100008 of the end effector 100004 to move the anvil 100008 from the open position ( Figure 5 ) moves to the closed position ( Figure 4 ). The first stroke portion may include, for example, approximately 0.100"-0.250" of the travel of the firing drive 100250. The first stroke portion may be defined as the distance between the second wedge 100114 and the second trailing edge 100255, and therefore, the distance that the firing drive 100250 may travel until the second wedge 100114 blocks the second trailing edge 100255 to prevent further displacement of the firing drive 100250, as shown in FIG. Fig. 22 shown.

[0108] Use of the firing drive 100250 with the lockout system 100100 enables the clinician to lock the end effector 100004 in the open state ( Figure 5 ) and closed state ( Figure 4 ) to grasp tissue, for example, when a staple cartridge having a first authentication key is positioned in the end effector. However, in the absence of a sufficient second authentication key, the firing drive 100250 is prevented from being further advanced through the staple cartridge. The firing drive 100250 allows the staple cartridge including the first authentication key to maintain some functionality (i.e., thereby allowing the end effector 100004 to be opened and closed), but prevents the firing drive 100250 from advancing through a portion of its stroke, which may result in damage to patient tissue (moving the knife through a staple cartridge that may not include staples therein).

[0109] See now Fig.23, a surgical stapling system 100300 including a firing actuator 100302 and a locking system 100310 is provided. The firing actuator 100302 and the locking system 100310 can be used with an end effector 100004. The firing actuator 100302 and the locking system 100310 can be used to replace the firing drive 100028 and the locking system 100100 in the surgical stapling system 100000.

[0110] The firing actuator 100302 includes a firing drive 100304, a first push rod 100306 attached to an upper end 100301 of the firing drive 100304, and a second push rod 100308 attached to a lower end 100303 of the firing drive 100304. The first push rod 100306 and the second push rod 100308 can be driven using any suitable drive system (such as a motor drive system) to move the firing drive 100304 from a proximal position (such as a proximal position) to a proximal position. Fig.23 The firing drive 100304 is driven to the distal position (as shown). An exemplary motor drive system is described in U.S. Patent Application Publication No. 2015 / 0173756, which is hereby incorporated by reference in its entirety. The firing drive 100304 also includes: a first cam 100305, which is configured to engage the first jaw of the end effector; a second cam 100307, ​​which is configured to engage the second jaw of the end effector; and a knife 100309, which is configured to cut tissue after the end effector is closed. As the firing drive 100304 is advanced distally, the first cam 100305 and the second cam 100307 control the distance or tissue gap between the platform of the nail magazine and the anvil. Driving the firing drive 100304 toward the distal position causes the nail to be deployed from the nail magazine, as described elsewhere herein. Driving the firing drive 100304 can cause the anvil to rotate distally toward the closed position (first stroke portion) and then cause the staples to be deployed from the staple cartridge when the firing drive 100304 is fired (see stroke portion).

[0111] The first push rod 100306 includes a first recess 100320 defined therein. The first recess 100320 includes a first leading edge 100322, a first trailing edge 100324, and a first sidewall 100326 extending from the first leading edge 100322 to the first trailing edge 100324. Similarly, the second push rod 100308 includes a second recess 100330 defined therein. The second recess 100330 includes a second leading edge 100332, a second trailing edge 100334, and a second sidewall 100336 extending from the second leading edge 100332 to the second trailing edge 100334.

[0112] The locking system 100310 includes a first locking member 100340, which includes a first locking arm 100342, a first cam surface 100344 and a first spring 100346. The first locking member 100340 can be in an unlocked state (a state in which the first locking arm 100342 is rotated within the first recess 100320, see Fig.24 ) and the unlocked state (a state in which the first locking arm 100342 rotates away from the first recess 100320, see Fig.23 ). The first spring 100346 can be configured to rotationally bias the first lockout 100340 into a locked state. The first lockout 100340 can be pivotally coupled to an elongated channel of an end effector, such as the elongated channel 100007 of the end effector 100004, but can be pivotally coupled at any suitable location in the stapling instrument, such as in a shaft.

[0113] The locking system 100310 also includes a second locking member 100350, which includes a second locking arm 100352, a second cam surface 100354 and a second spring 100356. The second locking member 100350 can be in an unlocked state (a state in which the second locking arm 100352 is rotated within the second recess 100330, see Fig.24 ) and the unlocked state (a state in which the second locking arm 100352 rotates away from the second recess 100330, see Fig.23 ). The second spring 100356 is capable of rotationally biasing the second locking member 100350 into a locked state. The second locking member 100350 is pivotally coupled to the elongated channel of the end effector, such as the elongated channel 100007 of the end effector 100004, but is pivotally coupled to any suitable position in the stapling instrument, such as in the shaft. The first locking arm 100342 and the second locking arm 100352 are pivotally coupled to the same lateral side of the elongated channel. Alternatively, the first locking arm 100342 and the second locking arm 100352 are pivotally coupled to different lateral sides of the elongated channel.

[0114] In use, the lockout system 100310 prevents advancement of the firing drive 100304 unless a compatible and unused staple cartridge is positioned in the first jaw of the end effector. Similar to the above, the staple cartridge includes two discrete and separately acting authentication keys, wherein the first authentication key is configured to be able to transition the first lockout 100340 from a locked state to an unlocked state, and the second authentication key is configured to be able to transition the second lockout 100350 from a locked state to an unlocked state, as described in more detail below.

[0115] The first lockout 100340 and the second lockout 100350 are designed so that either of the lockouts can by itself prevent the firing driver 100304 from moving distally through the staple cartridge. The lockout arm and spring are configured so that the lockout can individually block one of the drive rods of the firing driver 100304. A staple cartridge, such as the staple cartridge 100360, for example, includes a first key 100362 extending from a proximal end of a cartridge body 100364 thereof and including a first camming surface 100363. When the staple cartridge 100360 is disposed in the elongated channel, the first camming surface 100363 engages the first camming surface 100344 to rotate the first lockout 100340 to an unlocked state. With the first lockout 100340 in an unlocked state, the first push rod 100306 is permitted to drive the firing drive 100304 through the nail magazine 100360 (if the second lockout 100350 is also in an unlocked state, as described in more detail below).

[0116] In addition to the above, the nail magazine 100360 includes a second key 100366, which extends from the proximal end of the sliding member 100368 and includes a second camming surface 100369. It is worth noting that Fig.23 As shown, the slide 100368 is positioned in the proximal unfired position, thereby indicating that the nail magazine 100360 is an unused nail magazine (i.e., no nails in the nail magazine have been deployed therefrom). When the nail magazine 100360 is removably positioned in the first jaw, the second key 100366 engages the second lockout 100350. When the nail magazine 100360 is moved proximally to place the nail magazine 100360 in the elongated channel, the second cam movement surface 100369 engages the second cam surface 100354 to rotate the second lockout 100350 to an unlocked state. When the second lockout 100350 is in the unlocked state, the second push rod 100308 is allowed to drive the firing driver 100304 through the nail magazine 100360 (if the first lockout 100340 is also in the unlocked state, as described above).

[0117] In addition to the above, the first lockout 100340 includes a compatibility lockout. The second lockout 100350 includes a used magazine lockout, but is also used as a compatibility lockout. In order to unlock the second lockout 100350, two conditions about the slider of the nail magazine must be met, that is, the slider must be in a proximal unfired position and the slider must have a sufficient authentication key. In use, if the clinician attempts to drive the firing driver 100304 distally with one or two lockouts in their respective locked positions, its locking arm will engage the corresponding rear edge of the recess to stop the distal advancement of the firing driver 100304. Similar to the above, the first recess 100320 and the second recess 100330 may include a certain width (the distance from the leading edge to the trailing edge) that enables the firing driver 100304 to move through the first stroke portion to move the anvil to the closed position before the locking arm engages its corresponding rear edge to stop the distal translation of the firing driver 100304. Thus, the lockout system 100310 will still allow the clinician to transition the end effector between the open position and the closed position even if the installed staple cartridge is not certified and / or is in a spent state, but will not allow the firing drive 100304 to pass through the staple cartridge. Fig.24 , the nail magazine 100360 has been replaced by the first replacement nail magazine 100370, which does not include a first key on its magazine body 100374 or a second key on its slide 100378. Therefore, when the first replacement nail magazine 100370 is placed in the first jaw, both the first lockout 100340 and the second lockout 100350 remain in their respective locked positions, but as described above, the firing drive 100304 can still move distally to close the end effector. Alternatively, the distal movement of the firing drive 100304 can be prevented when one or both lockouts are in their respective locked positions, and the end effector cannot be closed by the firing drive 100304 unless the two lockouts have been released.

[0118] Many of the surgical instrument systems described herein are actuated by electric motors; however, the surgical instrument systems described herein may be actuated in any suitable manner. According to the present disclosure, the surgical instrument systems described herein may be actuated by, for example, a manually operated trigger.
