Abstract
The present disclosure relates to a surgical fastener applying apparatus for applying fasteners to body tissue. The apparatus includes a cartridge receiving half-section defining an elongated channel member configured to releasably receive a firing assembly and a single use loading unit. A lockout structure prevents insertion of the single use loading unit into the channel member after the firing assembly is mounted to the cartridge receiving half-section. Alternatively, the lockout structure prevents full insertion of the firing assembly into the cartridge receiving half-section, if the single use loading unit is not engaged with the firing assembly.
Description
FIELD

The present disclosure relates to a surgical fastener applying apparatus and, more particularly, to a surgical fastener applying apparatus having reusable and disposable components.


BACKGROUND

Surgical fastener applying apparatus, wherein tissue is first grasped or clamped between opposing jaw structures and then joined by means of surgical fasteners, are well known in the art. In some such apparatus, a knife is provided to cut the tissue which has been joined by the fasteners. The fasteners are typically in the form of surgical staples, although, other surgical fasteners may also be utilized, such as, for example, clips or two part polymeric surgical fasteners.


Surgical fastener applying apparatus typically include two elongated beam members which are used to capture or clamp tissue therebetween. Typically, one of the beam members carries a disposable cartridge assembly which houses a plurality of staples arranged in at least two lateral rows, while the other beam member includes an anvil which defines a surface for forming the staple legs as the staples are driven from the cartridge assembly. Where two part fasteners are used, the beam member which includes the anvil carries a mating part of the two part fastener, e.g. the receiver. Generally, the staple formation process is affected by the interaction between one or more longitudinally moving camming members and a series of individual staple pushers. As the camming members travel longitudinally through the cartridge carrying beam member, the individual pusher members are biased upwardly into a backspan of the staples supported within the cartridge assembly to sequentially eject the staples from the cartridge. A knife may be provided to travel with the camming members between the staple rows to cut the tissue between the rows of formed staples. An example of such an instrument is disclosed in U.S. Pat. No. 7,631,794, which is incorporated herein in its entirety by reference.


Because of the dangers associated with improper sterilization of surgical apparatus, fastener applying apparatus are typically disposable after use. Although the cartridge assembly may be replaced to perform multiple fastener applying operations on a single patient, the staple applying apparatus is typically disposable after a surgical procedure has been completed. This requirement of disposability may increase the costs associated with surgical procedures. Although reusable fastener applying apparatus have been developed, such apparatus can be overly complex and prove difficult to sterilize.


A need exists in the art for a fastener applying apparatus which includes reusable components, is not overly complex and is configured to facilitate proper sterilization after use in a surgical procedure.


SUMMARY

The present invention relates to a surgical fastener applying apparatus for applying surgical fasteners to tissue. In an embodiment of the present disclosure, a surgical fastener applying apparatus includes an anvil half-section, a cartridge receiving half-section defining an elongated channel member, and a single use loading unit and a firing assembly configured to be received within the channel member. The firing assembly may include a lockout structure that prevents full insertion of the single use loading unit into the channel member after the firing assembly is mounted in the channel member.


In an embodiment, the single use loading unit and the firing assembly together form a single disposable unit when the single use loading unit is engaged with the firing assembly.


In an embodiment, the lockout structure may define a first position which prevents the single use loading unit from mating with the firing assembly, and a second position which allows the single use loading unit to mate with the firing assembly. The lockout structure is configured to move between its first position and its second position. However, the lockout structure is obstructed from moving from the first position to the second position when the firing assembly is supported within the channel member.


In an embodiment, the lockout structure includes a spring-loaded knob with a retainer pin. The retainer pin is operatively connected to a cam bar of the firing assembly. When the lockout structure is in the first position, the cam bar is in a forward position relative to the firing assembly, thus preventing a proximal end of the single use loading unit from entering a distal end of the firing assembly.


In an embodiment, the lockout structure includes a spring-loaded button mounted on top of a knife actuating bar of the firing assembly. The spring-loaded button is configured to effect pivotal movement of the knife actuating bar through a groove defined on a bottom surface of the firing assembly. When the lockout structure is in the first position, the knife actuating bar is in a normal position, which prevents entry of a proximal end of the single use loading unit into a distal end of the firing assembly.


In an embodiment, the present disclosure provides a surgical fastener applying apparatus including an anvil half-section, a cartridge receiving half-section defining an elongated channel member, and a single use loading unit and a firing assembly configured to be received within the channel member. The firing assembly may include a lockout structure that prevents full insertion of the firing assembly into the channel member, if the single use loading unit is not mounted to the firing assembly.


In an embodiment, the lockout structure may define a first position which prevents full insertion of the firing assembly into the channel member, and a second position which allows full insertion of the firing assembly into the channel member. The lockout structure is configured to move between its first position and its second position. However, the lockout structure is obstructed from moving from the second position to the first position when the firing assembly is engaged with the single use loading unit.


In an embodiment, the lockout structure includes a rotary knob which is removably mountable to a slot defined on a sidewall of the channel member. The rotary knob is movable through the slot to a position blocking entry of the single use loading unit into the channel member.


In an embodiment, the present disclosure provides a surgical fastener applying apparatus including an anvil half-section, a cartridge receiving half-section defining an elongated channel member, and a single use loading unit and a firing assembly mountable to the channel member. The firing assembly may include a lockout structure mountable to the channel member. The lockout structure may prevent insertion of the single use loading unit into the channel member, if the firing assembly is secured in the cartridge receiving half-section.


In an embodiment, the lockout member includes a spring-loaded switch which may slide through a slot defined on a sidewall of the firing assembly. As the spring-loaded switch slides through the slot, the lockout member transitions between the first and second positions.

DETAILED DESCRIPTION

Embodiments of the presently disclosed surgical fastener applying apparatus in accordance with the present disclosure will now be described in detail with reference to the drawings wherein like reference numerals identify similar or identical structural elements. As used herein, as is traditional, the term “proximal” refers to the part of the apparatus which is closer to the user and the term distal refers to the part of the apparatus which is further away from the user.


Referring to FIGS. 1-3, surgical stapler 10 includes an anvil half-section 12, a cartridge receiving half-section 14, a clamping lever 16, a single use loading unit 18 (hereinafter “SULU”) and a firing assembly 20. In an embodiment, anvil half-section 12, cartridge receiving half-section 14 and clamping lever 16 are constructed to be reusable components and, as such, are constructed from a biocompatible material suitable for sterilization and repeated use, e.g., stainless steel. In contrast, SULU 18 and firing assembly 20 are constructed to be disposable and, as such, may be constructed from any suitable biocompatible material, e.g., plastics, metals, combinations thereof, having the requisite strength characteristics.


Referring to FIGS. 3-7, cartridge receiving half-section 14 defines an elongated channel member 22 which defines a U-shaped channel 24 having a distal portion 24a dimensioned to releasably receive a SULU 18 and a proximal portion 24b dimensioned to releasably receive firing assembly 20. U-shaped channel may have a flat bottom and straight legs in cross-section or it may have a slightly rounded bottom and/or at least one curved leg. In cross-section, the bottom of the U may connect with the legs by a sharp corner or at least one slightly rounded corner. Firing assembly 20 includes a stationary housing 26 (see also FIG. 12) having a proximal end including openings 28 which receive ends of pivot members 29 (FIG. 12). Pivot members 29 pivotally support a locking member 206 on a proximal end of stationary housing 26 and extend through openings 28 into recesses 30 formed in a proximal portion of cartridge receiving half-section 14 to releasably secure the proximal end of firing assembly 20 within the proximal portion 24b of channel member 22 as will be discussed in further detail below. The distal end of firing assembly 20 defines a triangular cutout 64d. Triangular cutout 64d may be a triangle or may be a triangle having sharp corners or at least one rounded or chamfered corner, and may have no equal sides or two or three equal sides. Cutout 64d is positioned to receive a protrusion 65 formed on an inner wall of channel member 22 (see FIGS. 9A-9C) to releasably secure the distal end of firing assembly 20 within channel member 22. The structure of firing assembly 20 will also be discussed in further detail below. Likewise, SULU 18 includes a pair of distal protrusions 32 which are positioned in cutouts 34 formed at the distal end of channel member 22 to releasably secure SULU 18 within the distal portion 24a of channel member 22. During assembly, firing assembly 20 must be inserted into proximal portion 24b of channel member 22 before SULU 18 is inserted into distal portion 24a of channel member 22 as will be discussed below. To position SULU 18 in channel member 22, protrusions 32 on SULU 18 are positioned within cutouts 34 while SULU 18 is positioned above and at an angle to channel member 22. Thereafter, SULU 18 can be rotated downwardly into distal portion 24a of U-shaped channel 24. This allows for the drive components of firing assembly 20 to properly align with components of SULU 18 and also facilitates engagement of the firing assembly 20 with a knife 40 (FIG. 17) supported within SULU 18. A proximal end of SULU 18 includes an outwardly extending serrated surface 42 (FIG. 7) to facilitate gripping of the proximal end of SULU 18 to allow for removal and/or replacement of SULU 18 from channel member 22. Prior to movement of stapler 10 to the clamped position, as will be discussed below, serrated gripping surface 42 will not fully seat within distal portion 24a of channel member 22.


Referring to FIGS. 8-12, firing assembly 20 includes stationary housing 26, a knife actuating bar 44, a cam bar 46, a guide block 48, a firing lever 50, a slide block 52, a pedal 54 and the pivotal locking member 206 (FIG. 12). In an embodiment, stationary housing 26 includes a U-shaped frame 60 including a bottom wall 62 and a pair of sidewalls 64. The distal end of each sidewall 64 defines a proximal step 64b, a distal angled portion 64c (FIG. 9) and the triangular cutout 64d. As discussed above, triangular cutout 64d is positioned to receive the protrusion 65 (FIG. 9B) formed on an inner wall of channel member 22. A proximal end of each sidewall 64 includes a pair of transversely extending deformable wall portions 66 (FIG. 11) which are spaced from a proximal end of slide block 52 and define an area between wall portions 66 and slide block 52 for pivotally receiving locking member 206 as will be discussed in further detail below.


Guide block 48 includes a body defining three longitudinal slots 70a-c and a pair of outwardly extending protrusions 72. In an embodiment, each protrusion 72 is cylindrical and includes a tapered portion 72a (FIG. 9). Cylindrical protrusion 72 may be a cylinder with a circular cross-section, or may have a slightly oblong cross-section. Additionally, cylindrical protrusion 72 may have a blunt end or a slightly rounded or tapered end. Alternately, other protrusion configurations are envisioned. Protrusions 72 are dimensioned to be received in openings 74 (FIG. 12) formed in sidewalls 64 of stationary housing 26 to axially fix guide block 48 within the distal end of stationary housing 26. Protrusions 72 allow for a degree of pivotal movement of guide block 48 within U-shaped frame 60. As will be discussed in further detail below, guide block 48 is pivotal from a first position (FIG. 19) in locking engagement with notches 49 and 51 of knife actuating bar 44 to a second position (FIG. 26) disengaged from notches 49 and 51 of knife actuating bar 44 in response to movement of stapler 10 to the clamped position. A torsion spring is provided about protrusion 72 to urge guide block 48 into locking engagement with notches 49 and 51. Each of slots 70a and 70c is dimensioned to slidably receive a respective sidewall 114 of cam bar 46. Similarly, slot 70b is dimensioned to slidably receive knife actuating bar 44.


Slide block 52 includes a hub 80 which includes a resilient finger 80a configured to be snap-fit into a pivot hole 82 formed in firing lever 50. Firing lever 50 is pivotal about hub 80 when the slide block 52 is in a retracted position to facilitate actuation of the firing assembly 20 from either side of stapler 10. Pedal 54 is reciprocally received within a hole 84 formed in slide block 52. Pedal 54 includes a split body portion 54a which is configured to straddle a proximal end 102 of knife actuating bar 44. In an embodiment, split body portion 54a includes an angled distal surface 86. A pin 88 extends upwardly from pedal 54 through hole 84 in slide block 52. A biasing member 90 is positioned between split body portion 54a and slide block 52, about pin 88 to urge pedal 54 downwardly away from slide block 52 to an extended position. In the retracted position of slide block 52, pedal 54 is received in a cutout 55 formed in a bottom wall 22a of channel member 22 (FIG. 20).


Firing lever 50 includes first and second finger engagement members 50a and 50b, either one of which can be selectively engaged to move the firing lever 50 through a firing stroke from either side of stapler 10. An arcuate recess 94 (FIG. 12B) is formed in a bottom surface of firing lever 50 which slidably receives pin 88 of pedal 54 to define the range of rotation through which firing lever 50 can pivot about hub 80 of slide block 52. As used herein, a firing stroke is defined as movement of firing lever 50 from a fully retracted position (FIG. 25) to a fully advanced position (FIG. 30). A stop recess 94a is formed at each end of arcuate recess 94. Stop recesses 94a are configured and dimensioned to receive the end of pin 88 of pedal 54 to prevent pivotal movement of firing lever 50 about hub 80 during a firing stroke of surgical stapler 10. More specifically, when the firing assembly 20 is actuated to advance slide block 52 distally within stationary housing 26, angled distal surface 86 of pedal 54 engages channel member 22 and is cammed out of cutout 55 (FIG. 27) to urge pin 88 upwardly into a stop recess 94a to prevent pivotal movement of firing lever 50 during movement of firing lever 50 through a firing stroke. As is evident, pin 88 must be positioned beneath a stop recess 94a to allow pedal 54 to lift upwardly from cutout 55 to allow firing lever 50 to be moved through the firing stroke. Thus, firing lever 50 must be pivoted to one side or the other of firing assembly 20 before the firing lever 50 can be moved through a firing stroke.


Knife actuating bar 44 includes a proximal end having a stepped portion 100 which includes a proximal first step 102 having a first height and a second step 104 having a second height which is greater than the first height. A distal end of actuating bar 44 includes an upturned hook portion 106 and upper and lower notches 49 and 51. A finger 108 projects upwardly from knife actuating bar 44 between first and second steps 102 and 104. As shown in FIG. 27, finger 108 is slidably received within a recess 110 formed in an underside of slide block 52. When slide block 52 is advanced distally within stationary housing 26, finger 108 moves within recess 110 such that slide block 52 moves in relation to knife actuating bar 44 until finger 108 engages a wall 112 (FIG. 32) defining a proximal end of recess 110. When finger 108 engages wall 112, further distal movement of slide block 52 will also effect distal movement of knife actuating bar 44. As will be evident below, this arrangement allows for staples to be ejected from SULU 18 prior to cutting of tissue.


Referring to FIGS. 12 and 12A, cam bar 46 includes a pair of sidewalls 114 and a base wall 116 (FIG. 12A). The proximal end 114a of each sidewall 114 includes a raised wall portion 118. Each raised wall portion 118 is configured to be fixedly received in a slot (not shown) formed in an underside of slide block 52 to fixedly secure the proximal end of cam bar 46 to slide block 52. Alternately, slide block 52 may be molded about the proximal end of knife actuating bar 44. The distal end of each sidewall 114 includes an angled camming surface 114b. Base wall 116 defines a distally extending elongated slot 123 (FIG. 12A) which extends from the distal end of cam bar 46 along a substantial length of the cam bar 46 and a proximally extending longitudinal slot 121. Slot 121 is positioned to facilitate the passage of pedal 54 through cutout 55 of channel member 22 when slide block 52 is in the retracted position. See FIG. 27.


Sidewalls 114 of cam bar 46 are slidably positioned in slots 70a and 70c of guide block 48 and knife actuating bar 44 is slidably positioned in longitudinal slot 70b of guide block 48. When firing assembly 20 is supported in channel member 22 and firing lever 50 is pivoted to one side of stationary housing 26 and pushed distally, slide block 52 is moved distally within stationary housing 26. As slide block 52 begins to move distally, tapered surface 86 of pedal 54 engages a proximal edge of channel member 22 defining cutout 55 to urge pedal 54 upwardly out of cutout 55, through slot 121 of cam bar 46, and onto an inner surface of stationary housing 26 of firing assembly 20 (FIG. 27). As this occurs, pin 88 of pedal 54 moves into a stop recess 94a to prevent further pivotal movement of firing lever 50. If firing lever 50 is not pivoted to a position in which pin 88 is positioned beneath a stop recess 94a, pedal 54 will be prevented from moving upwardly out of cutout 55 and firing lever 50 will be prevented from moving through a firing stroke. As firing lever 50 is moved distally, finger 108 moves within recess 110 such that knife actuating bar 44 remains stationary as cam bar 46 is advanced distally. When finger 108 engages proximal wall 112 defining recess 110, knife actuating bar 44 is moved distally with slide block 52 and cam bar 46. As will be discussed below, when cam bar 46 and knife actuating bar 44 are moved distally within stationary housing 26 of firing assembly 20 and channel member 22, angled camming surfaces 114b of cam bar 46 are moved through SULU 18 to eject fasteners from SULU 18. Simultaneously, although with a preset delay equal to the length of recess 110 (FIG. 32), knife actuating bar 44 drives a knife blade 40 through SULU 18 to dissect tissue.


U.S. Pat. No. 7,631,794 (“the '794 patent”) discloses a surgical fastener applying apparatus which includes a firing assembly similar to that described above. The '794 patent is incorporated herein by reference in its entirety.



FIGS. 13-17 illustrate SULU 18. Referring to FIG. 17, SULU 18 includes a body 120, a plurality of staple pushers 122 (only one is shown), a bottom cover 124, a knife 40 having an angled sharpened leading edge or blade 40a, a plurality of staples 126 (only one is shown), and a pivotally mounted safety lockout 128. A proximal end of body 120 includes a flexible finger 120a which projects slightly beyond the outer wall defining body 120. Finger 120a frictionally engages an inner wall of channel member 22 to retain the proximal end of SULU 18 within channel member 22 when SULU 18 is releasably positioned within channel member 22. As is known in the art, body 120 has a plurality of rows of staple retaining slots 130, e.g., four, six, etc. and a linear slotted knife track 132 centrally disposed in body 120. Surgical stapler 10 can be dimensioned to receive or accommodate SULU's of different staple line lengths including, e.g., 60 mm, 80 mm and 100 mm. Knife 40 includes a downturned hook portion 40b which is positioned to engage upturned hook portion 106 (FIG. 12) of knife actuating bar 44 when SULU 18 is positioned within channel member 22.


In the illustrated embodiment, body 120 includes two staggered rows of slots 130 formed on either side of linear slotted knife track 132. The staggered rows of slots 130 extend beyond the distal end of knife track 132 to facilitate staple formation beyond the distal end of the stroke of the knife blade 40.


Staple pushers 122 may be configured to extend into one or more slots 130. In an embodiment, a single pusher is associated with each slot 130. Alternately, as illustrated in FIG. 17, each pusher 122 can be configured to extend into two adjacent slots 130 and is positioned beneath respective staples 126 which are retained in slots 130. As is known in the art, each pusher 122 includes a lower cam surface 122a which is positioned to engage one of cam surfaces 114b (FIG. 12) on the distal end of cam bar 46 such that movement of cam bar 46 through SULU 18 sequentially lifts each respective pusher 122 within its respective slot or slots 130 to eject staples from slots 130.


Bottom cover 124 partially encloses a channel 125 (FIG. 18) formed within the cartridge body 120. A longitudinal ridge 134 is formed on an upper surface of bottom cover 124 and provides a bearing surface for a knife supporting member 136 which is secured to a bottom edge of knife 40. Knife 40 may be secured to supporting member 136 via pins, welding or other known fastening techniques. During a firing stroke, knife 40 is guided along knife track 132 as the firing lever 50 is advanced through channel member 22. A pair of slots 138 is defined between the sides of ridge 134 and an outer wall of cartridge body 120. Longitudinal ridge 134 is positioned within body 120 and dimensioned to be slidably received in elongated slot 120 (FIG. 12A) of cam bar 46 such that cam bar 46 is slidably movable through cartridge body 120 about longitudinal ridge 134 to eject staples 126 from SULU 18.


Safety lockout 128 is pivotally disposed on an upper proximal end of body 120 and is pivotal about a pivot member 150 from a locked orientation (FIG. 26) to unlocked orientation (FIG. 34). Pivot member 150 is received in openings 154 in body 120. A biasing member, e.g., spring 152, is positioned between knife supporting member 136 and safety lockout 128 to urge safety lockout 128 towards the unlocked orientation. Safety lockout 128 includes a proximal hook 156 which is positioned to receive an engagement member 158 formed on the knife 40 to retain the safety lockout 128 in the locked orientation when the knife 40 is in the retracted position (FIG. 19). When the knife 40 is moved towards the advanced position during a firing stroke, engagement member 158 is moved away from proximal hook 156 to allow safety lockout 128 to pivot towards the unlocked position in response to the urging of spring 152. It is noted that safety lockout 128 is prevented from pivoting to the unlocked position when the anvil half-section 12 and cartridge receiving half-section 14 are in the clamped position because the top surface 128a of safety lockout 128 engages an inner surface of anvil half-section 12 to prevent pivoting of safety lockout 128. Safety lockout 128 defines a slot 160 dimensioned to slidably receive the knife 40. In the retracted position of the knife 40, the leading edge 40a of knife 40 is confined within slot 160 safety lockout 128 to prevent accidental engagement and injury to medical personnel with leading edge 40a of knife 40.


Referring again to FIGS. 2-3, anvil half-section 12 includes a proximal handle portion 12a and a distal anvil portion 12b. Anvil portion 12b includes a staple deforming portion 198 which, as known in the art, includes a plurality of staple deforming recesses and faces a top surface of SULU 18 when SULU 18 is positioned in the channel member 22. As is also known in the art, the staple deforming portion 198 includes a central longitudinal slot (not shown) for receiving the knife 40 (FIG. 17) as the knife 40 is moved through the SULU 18. The staple deforming portion 198 can be formed integrally with anvil half-section 12, or in the alternative, secured to anvil half-section 12 by a fastening process such as welding. A pair of locating fingers 170 (FIG. 3) are positioned adjacent the proximal end of the staple deforming portion 198 of anvil portion 12b. Locating fingers 170 are received in grooves in SULU 18 to properly align SULU 18 with staple determining portion 198 when the apparatus is in a clamped position.


A central portion of anvil half-section 12 includes a pair of cylindrical lateral support members 172. During assembly of anvil half-section 12 and cartridge receiving half-section 14, lateral support members 172 are supported in U-shaped recesses 174 defined in a central portion 173 of cartridge receiving half-section 14 (FIG. 28). A distal wall 173a of central portion 173 defines a tissue stop (FIG. 3). Lateral support members 172 are also positioned to be received in cutouts 176 formed on spaced flange portions 178 of clamping lever 16 when the clamping lever 16 is moved to the clamped position (FIG. 2B). Proximal handle portion 12a is ergonomically formed and includes a thumb-engaging abutment 180 and a gripping portion 182. A proximal end of handle portion 12a includes a downwardly extending finger 184 which includes a pair of opposed teardrop shaped protrusions 186 which will be discussed in further detail below. Alternately, protrusions 186 may assume a variety of configurations.


Cartridge receiving half-section 14 includes spaced centrally disposed U-shaped recesses 174 positioned to support lateral support members 172 of anvil half-section 12. The proximal end of cartridge receiving half-section 14 includes a pair of vertical support members 188. Each vertical support member 188 includes an elongated vertical slot 188a having a rounded bottom surface. Vertical slots 188a are dimensioned to receive protrusions 186 formed on finger 184 of anvil half-section 12 (FIG. 21) when the anvil half-section 12 is supported on the cartridge receiving half-section 14 during assembly. By positioning protrusion 186 within the vertical slots 188a, anvil half-section 12 can be pivoted in a scissor-like manner with respect to the cartridge receiving half-section 14 between open and closed positions. In an embodiment, protrusions 186 have a teardrop profile. At least one sidewall of cartridge receiving half-section 14 includes a depression 189 (see FIG. 3) which will be discussed in further detail below.


Clamping lever 16 also includes a handle portion 190 including a grip 190a and a thumb engaging abutment 192. As discussed above, a pair of spaced flange portions 178 is supported on the distal end of clamping lever 16. Each flange portion 178 defines a cutout 176 dimensioned to receive a respective lateral support member 172 of anvil half-section 12 when stapler 10 is moved towards clamped position (FIG. 2B). The distal end of clamping lever 16 also defines a pair of openings 194 which are dimensioned to receive a pivot member 187. Pivot member 187 is dimensioned to extend through openings 195 in cartridge receiving half-section 14 and openings 194 in clamp lever 16 to pivotally secure clamp lever 16 to cartridge receiving half-section 14.


As shown in FIG. 3A, an inner wall of clamping lever 16 includes a protrusion 201. Protrusion 201 is positioned within depression 189 (FIG. 2A) formed in the sidewall of cartridge receiving half-section 14 to releasably retain clamp lever 16 in the unclamped position or open position (FIG. 2A).


In order to load firing assembly 20 into proximal portion 24b of channel member 22, the stationary housing 26 of firing assembly 20 is slid into the channel member 22 through the proximal end of channel member 22 until pivot members 29 are received in recesses 30 formed in the proximal end of channel member 22. After firing assembly 20 is loaded, the SULU 18 can be loaded into distal portion 24a in the manner discussed above.


Referring to FIGS. 2 and 2B, after SULU 18 and firing assembly 20 are loaded into channel member 22, anvil section 12 can be assembled to cartridge receiving half-section 14. To attach anvil half-section 12 to cartridge receiving half-section 14, protrusions 186 of fingers 184 are positioned in vertical slots 188a of vertical support member 188 of cartridge receiving half-section 14. Thereafter, anvil half-section 12 is rotated towards cartridge receiving half-section 14 to position lateral supports members 172 in U-shaped recesses 174.


In order to position surgical stapler 10 in the clamped position, clamping lever 16 is rotated in a counter-clockwise direction from the position shown in FIG. 2A. As clamping lever 16 is rotated, lateral support members 172 are received in cutouts 176 (FIG. 2) of flange portions 178 and cammed towards cartridge receiving half-section 14. As shown in FIG. 3, a spring member 200 is secured to an inner surface of clamping lever 16, such as by welding, at a position to engage cartridge receiving portion 14 to urge clamping lever 16 to the non-clamped position shown in FIG. 2A. In the clamped position shown in FIG. 1, the staple deforming portion 198 is positioned in close approximation with the top surface of SULU 18.


Referring to FIGS. 3, 3A and 12, as discussed above, a pivotal locking member 206 is pivotally supported on the proximal end of stationary housing 26 of firing assembly 20. Pivotal locking member 206 includes pivot members 29 which extend through openings 28 defined in stationary housing 26. A finger engagement member 212 is positioned on one end of locking member 206 and a latch portion 210 is positioned on the other end of locking member 206. Latch portion 206 includes a hook member 210a. A biasing member 214 is positioned about a pivot member 29 to urge latch portion 210 inwardly towards stationary housing 26 of firing assembly 20. When locking member 206 is secured on firing assembly 26, latch portion 210 extends downwardly through an opening 216 in a proximal end of stationary housing 26 to a position below a bottom surface of channel member 22 (FIG. 20). As discussed above, the ends of pivot members 29 are received in cutouts 30 formed in the proximal end of cartridge receiving half-section 14 to releasably secure firing assembly 20 within proximal channel portion 24b of channel member 22 (FIG. 21). Cutouts 30 are partially defined by downturned fingers 220 to retain firing assembly 26 within channel member 22 (FIG. 3).


Referring to FIG. 3A, a proximal end of clamping lever 16 includes an engagement member, e.g., cylindrical post 218, which is positioned to be engaged by hook member 210a of latch portion 210 when the clamp lever 16 is moved to the clamped position (FIG. 27). Although a post is illustrated, other engagement member configurations are envisioned. As can be seen by viewing FIG. 27, as clamping lever 16 is moved towards the clamped position, an angled face 222 of latch portion 210 engages post 218. This engagement causes locking member 206 to pivot about pivot members 29 such that hook member 210a of latch portion 210 passes by and then snaps into engagement with post 218. To release latch portion 210 from post 218, engagement member 212 of locking member 206 is depressed to pivot latch portion 210 out of engagement with post 218. When this occurs, spring member 200 urges clamping lever 16 to the unclamped position.


Referring to FIGS. 3, 12, 19 and 26, as discussed above, guide block 48 is pivotally supported in stationary housing 26 of firing assembly 20. Guide block 48 includes a distally extending nose portion 220 (FIGS. 12 and 26) which rests beneath SULU 18 when SULU 18 is supported in channel member 22. The internal surface of guide block 48 includes locking surfaces 222 (FIG. 19) which are received in notches 49 and 51 of knife actuating bar 44 when the stapler 10 is in an unclamped position. When the SULU 18 is positioned in the channel member 22, prior to moving clamp lever 16 to the clamped position, SULU 18 is positioned atop nose portion 220 and is not fully seated in the channel member 22, as discussed above. When the stapler 10 is moved to the clamped position, locating fingers 170 (FIG. 3) engage a top surface of body 120 of SULU 18 to fully seat SULU 18 in channel member 22. As discussed above, locating fingers 170 are received in grooves in SULU 18 to properly position SULU 18 in relation to anvil portion 12b. As SULU 18 is fully seated in channel member 22, SULU 18 presses downwardly on nose portion 220 of guide block 48 to pivot guide block 48 about protrusions 72. When guide block 48 pivots, locking surfaces 222 move from notches 49 and 51 to unlock knife actuating bar 44 (FIG. 26). This configuration prevents movement of the knife actuating bar 44 in relation to guide block 48 prior to clamping to ensure that the knife actuating bar 44 and SULU knife 40 remain properly positioned for operational engagement prior to use.


Referring to FIGS. 24-28, when stapler 10 is in the clamped, unfired position, slide block 52 of firing assembly 20 is in the retracted position at the proximal end of channel member 22 and stationary housing 26. See FIG. 27. In this position, pedal 54 is positioned in cutout 55 of channel member 22 and pin 88 of pedal 54 is positioned in arcuate recess 94 of firing lever 50 beneath stop recesses 94a. As such, firing lever 50 can be pivoted to facilitate actuation of stapler 10 from either side of the stapler 10. In addition, in this position of slide block 52, finger 108 of knife actuating bar 44 is positioned adjacent the distal wall of recess 110 of slide block 52. Latch portion 210 of locking member 206 is also engaged with post 218 to retain clamping lever 16 in the clamped position.


Referring to FIG. 26, when slide block 52 is in the retracted position, knife 40 and cam surfaces 114b of cam bar 46 are positioned in the proximal end of SULU 18 and, proximal hook 156 of safety lockout 128 is positioned in engagement with engagement member 158 of knife 40 to retain safety lockout 128 in the locked orientation. In addition, downturned hook portion 40b of knife 40 is engaged with upturned hook portion 106 of knife actuating bar 44 to connect firing assembly 20 to knife 40 of SULU 18.


Referring to FIGS. 29-32, when the firing lever 50 is advanced distally in the direction indicated by arrow “A” in FIG. 29, slide block 52 is moved distally within stationary housing 26 of firing assembly 20 to effect corresponding movement of cam bar 46 and delayed movement of knife actuating bar 44. As discussed above, the delayed movement of the knife actuating bar 44 is equal to the length of recess 110 of slide block 52 and results from movement of finger 108 of knife actuating bar 44 within recess 110 of slide block 52. Movement of knife actuating bar 44 with slide block 52 begins when finger 108 abuts the proximal wall 112 of recess 110. As cam bar 46 is moved distally through stationary housing 26 of firing assembly 20, cam surfaces 114b on sidewalls 114 of cam bar 46 are advanced through SULU 18 to sequentially engage pushers 122 to eject staples 126 from slots 130 of body 120. Concurrently, since the distal end of knife actuating bar 44 is engaged with knife 40, knife 40, after the preset delay, is advanced through SULU 18 to incise tissue between the staple lines.


As shown in phantom in FIG. 32, when slide block 52 moves distally within stationary housing 26, pedal 54 rides up over channel member 22 and moves along inner surface of stationary housing 26 of firing assembly 20. When this occurs, pin 88 of pedal 54 moves into a stop recess 94a to prevent further pivotal movement of firing lever 50.


Referring to FIGS. 31 and 32, when knife 40 is moved distally within SULU 18, engagement member 158 of knife 40 is disengaged with proximal hook 156 of safety lockout 128.


Referring to FIGS. 33 and 34, when the firing lever 50 is returned to its proximal-most position to retract cam bar 46 and knife 40, and the locking member 206 is depressed to disengage latch portion 210 from post 218, spring 200 urges clamping lever 16 to its unclamped position to allow stapler 10 to move to the open position. In the open position, anvil half-section 12 is spaced from cartridge receiving half-section 14 and spring 152 (FIG. 17) pivots safety lockout 128 in the direction indicated by arrow B in FIG. 34 about pivot member 150 to its unlocked position such that safety lockout 128 projects upwardly from SULU 18. In the unlocked position, safety lockout 128 prevents movement of the stapler 10 back to the clamped position. In order to reuse stapler 10, used SULU 18 must be replaced with a new SULU 18.


During a surgical procedure, SULU 18 can be replaced multiple times to facilitate multiple uses of stapler 10 on a single patient. Since each SULU 18 is provided with a fresh knife 40, tearing of tissue is minimized. After the surgical procedure, the used SULU(S) 18 and the firing assembly 20 can be removed from the channel member 22 and disposed of in an appropriate manner. The anvil half-section 12, cartridge receiving half-section 14 and clamping lever 16 can now be sterilized, such as by autoclaving, and reused with a sterilized SULU 18 and firing assembly 20 in the manner discussed above. Because the locking member 206 forms part of the firing assembly 20 and is disposable, fewer areas remain on the reusable components for tissue and fluids to become trapped. As such, the reusable components of the apparatus can be more easily sterilized.


In the surgical stapler described above, the SULU 18 and the firing assembly 20 are independently secured to and independently removable from the channel member 22 of the cartridge receiving half-section 14. More specifically, in embodiments described above, the firing assembly 20 can be installed into and secured within the channel member 22 first, followed by the SULU 18. The SULU 18 engages the firing assembly 20 as the SULU 18 enters the channel member 22. In alternative embodiments, which are discussed below, the SULU 18 and the firing assembly 20 must be assembled to form a single disposable unit before the disposable unit can be secured within the channel member 22. In an embodiment, a lockout structure prevents independent insertion of either the SULU 18 or the firing assembly 20 into the channel member 22. In these embodiments, the SULU 18 must be assembled with the firing assembly 20 to form a single disposable unit before securing the single disposable unit within the channel member 22 of the cartridge receiving half-section 14. Specific embodiments are discussed below.



FIGS. 35A-B illustrate an alternate embodiment of the firing assembly 320. Similar to the embodiments described above, the firing assembly 320 includes a stationary housing 326 having a distal end 321 configured to receive a proximal end 319 of the SULU 318. The firing assembly 320 also includes a cam bar 346 and a knife actuating bar (not shown) movably positioned within stationary housing 326. Similar to the cam bar 46 described earlier, the cam bar 346 is configured to move through the SULU 318 to eject fasteners 126 (FIG. 17) from the SULU 18 upon actuation of the firing assembly 320.


For simplicity reasons, the knife actuating bar is not illustrated in FIGS. 35A-B, but it is substantially similar to the knife actuating bar 44 illustrated in FIG. 12. The knife actuating bar is configured to releasably engage the SULU 318 and may include an upturned hook portion 106 (FIG. 12) at a distal end thereof configured to releasably engage a downturned hook portion 40b (FIG. 17) of the knife 40 of the SULU 318.


The firing assembly 320 includes a spring-loaded knob 330 supported at the proximal end 323 of the stationary housing 326. The knob 330 is operatively connected with the cam bar 346 and the knife actuating bar. The knob 330 includes a spring 332 which may directly abut or engage the proximal ends of the cam bar 346 and the knife actuating bar. Spring 332 is normally in compression and urges cam bar 346 distally within stationary housing 326. Alternately, spring 332 may be engaged with the cam bar 346 via a slide block, e.g., slide block 52 in FIG. 12.


The knob 330 includes a retainer pin 334 operatively connected with the spring 332. The retainer pin 334 may have a plate-like configuration and is positioned perpendicular to a longitudinal axis “A” of the firing assembly 320. The retainer pin 334 has a lower end 336 which extends below the bottom surface 352 of stationary housing 326 of firing assembly 320. The bottom surface 352 of stationary housing 326 defines an elongated slot 354 which receives the lower end 336 of the retainer pin 334 such that the retainer pin 334 can move axially through the guiding slot 354. When the retainer pin 334 is at a proximal end of the guiding slot 354, the spring 332 is in a compressed state as illustrated in FIG. 35A. Conversely, when the retainer pin 334 is at a distal end of the guiding slot 354, the spring 332 is in an extended state as illustrated in FIG. 35B. Accordingly, by manipulating the position of the retainer pin 334, the cam bar 346 and the knife actuating bar can transition between a retracted position “R” (FIG. 35A) and a forward position “F” (FIG. 35B).


In the absence of any external influence, the spring 332, which is in compression, urges the cam bar 346 toward the forward position “F” (FIG. 35B). In the forward position, the cam bar 346 prevents the SULU 318 from being received in the distal end of the firing assembly 320. More specifically, the proximal end of SULU 318 is not configured to receive, or operatively engage, the distal end of the cam bar 346 and knife actuating bar when the cam bar 346 and knife actuating bar are in the forward position F.


To load the SULU 318 with the firing assembly 320, a clinician needs to first retract the cam bar 346 and the knife actuating bar to the retracted position “R” shown in FIG. 35A by sliding the retainer pin 334 against the bias of spring 332 to the proximal end of the slot 354. Next, the clinician places the proximal end 319 of the SULU 318 into the distal end 321 of the stationary housing 326 of the firing assembly 320. Then, the clinician releases the retainer pin 334, which, allows the cam bar 346 to spring forwardly to the forward position “F” to operatively engage the SULU 318.


To disengage the SULU 318 from the firing assembly 320, the clinician must first retract the cam bar 346 and the knife actuating bar to the retracted position “R” by moving the retainer pin 334 to the proximal end of the guiding slot 354. During this process, the cam bar disengages from the SULU 318. The clinician can then remove the proximal end 319 of the SULU 318 from the distal end 321 of the firing assembly 320. When the clinician releases the retainer pin 334, the cam bar 346 is urged forwardly by spring 332 to return to the forward position “F.”


As illustrated in FIG. 35C, the channel member 322 defines an indentation 324 on its bottom surface 326. The indentation 324 is dimensioned to receive the lower end 336 of the retainer pin 334 when the firing assembly 320 is positioned within the channel member 322 and the retainer pin 334 is in the forward position shown in FIG. 35B. Receipt of the retainer pin 334 in the indentation 324 of channel member 322 prevents movement of retainer pin 334 to its retracted position shown in FIG. 35A and, thus prevents insertion of SULU 318 into the stationary housing 326 of the firing assembly 320 when the firing assembly 320 is received in the channel member 322. More specifically, engagement between the retainer pin 334 and the indentation 324 prevents retraction of the cam bar 346. As a result, if the firing assembly 320 is mounted in the channel member 322 without the SULU 318, the cam bar 346 will be maintained in the forward position “F” preventing subsequent operative engagement of the SULU 318 with the firing assembly 320.


Similarly, if the firing assembly 320 and the SULU 318 are first engaged to form a single disposable unit, the SULU 318 cannot be disengaged from the firing assembly 320 once both are mounted in the channel member 322, because the indentation 324 prevents retraction of the cam bar 346.


In another embodiment illustrated in FIGS. 36A-36E, firing assembly 420 includes a stationary housing 426 having a distal end 421 configured to receive a proximal end 419 of the SULU 418 (FIG. 36E). The firing assembly 420 also includes a knife actuating bar 444 centrally located along the longitudinal axis “A” of the firing assembly 420 and a cam bar 445 including spaced sidewalls 445a (FIG. 36B).


The knife actuating bar 444 has a similar configuration as that of the knife actuating bar 44 described earlier. More specifically, the knife actuating bar 444 may include an upturned hook portion 406 at its distal end 408 configured to releasably engage a downturned hook portion 40b (FIG. 17) of knife 40 of the SULU 418.


In this embodiment, the knife actuating bar 444 is pivotally connected to a retainer member 446 located at a proximal end 423 of the firing assembly 420 via a pivotal connection 448. The stationary housing 426 of firing assembly 420 further defines an elongated groove or slot 450 in the bottom surface 452 thereof. The slot 450 is dimensioned to facilitate passage of the distal end 408 of the knife actuating bar 444 therethrough as the knife actuating bar 444 pivots relative to the retainer member 446. In the absence of any external influence, the knife actuating bar 444 is positioned above a bottom surface 452 of stationary housing 426 parallel to the longitudinal axis “A” of the firing assembly 420.


The firing assembly 420 further includes a button 454 mounted on top of the knife actuating bar 444 to effect pivotal movement of the knife actuating bar 444 in relation to pivotal connection 448. The button 454 may be positioned adjacent to the distal end 408 of the knife actuating bar 444. When the button 454 is depressed in the direction indicated by the arrow “D” as indicated in FIG. 36D, the knife actuating bar 444 rotates downwardly in a counterclockwise direction relative to the retainer member 446. During this process, the distal end 408 of the knife actuating bar 444 passes through the slot 450 and extends beyond the bottom surface 452 of stationary housing 426. A biasing member or spring (not shown) may be provided to urge button 454 to its non-depressed position, such that upon release of the button 454, the button 454 and knife actuating bar 444 return to their non-depressed or normal positions. Accordingly, by manipulating button 454, the knife actuating bar 444 can be selectively moved from the normal position within stationary housing 426 to the pivoted position extending through slot 450.


When the knife actuating bar 444 is in its normal position (FIG. 36A), SULU 418 cannot slide into the firing assembly 420 in the direction indicated by arrow “E” in FIG. 36E as the distal end 408 of the knife actuating bar 444 abuts against the proximal end 419 of SULU 418. Thus, to properly engage the proximal end 419 of the SULU 418 with the distal end of stationary housing 426 of the firing assembly 420, a clinician must first depress the button 454 to pivot the knife actuating bar 444 downwardly through the slot 450. When this occurs, the proximal end 419 of the SULU 418 is able to pass over the distal end 408 of knife actuating bar 444 and into the distal end 421 of the firing assembly 420. When the SULU 418 is properly positioned within the distal end of firing assembly 420, the clinician releases the button 454 to allow knife engagement bar 444 to engage the SULU 418. More specifically, as the distal end 408 of the knife actuating bar 444 moves upwardly, the upturned hook portion 406 of the knife actuating bar 444 engages the downward hook portion 40b (FIG. 17) of the knife 40 of the SULU 418 to secure firing assembly 420 to SULU 418.


To disengage the SULU 418 from the firing assembly 420, the upturned hook portion 406 of the knife actuating bar 444 must be disengaged from the downward hook portion 40b of the knife 40 (FIG. 17) of the SULU 418. To accomplish this, the distal end 408 of the knife actuating bar 444 is pushed downwardly through slot 450 by depressing button 454. As the distal end 408 of the knife actuating bar 444 moves downwardly, the upturned hook portion 406 disengages from the downward hook portion 40b (FIG. 17) of the SULU 418. While depressing the bar 444, the clinician removes the proximal end 419 of the SULU 418 from the distal end 421 of the firing assembly 420. Thereafter, the clinician releases the button 454 to restore the knife actuating bar 444 to its normal position.


In this embodiment, when the firing assembly 420 is mounted in the channel member 22 (FIG. 3), the bottom surface of the channel member 22 covers the slot 450, to prevent pivotal movement of the knife actuating bar 444 through slot 450. Accordingly, if the firing assembly 420 is mounted in the channel member 22 without the SULU 418 already operatively engaged with the firing assembly 420, the SULU 418 cannot be subsequently loaded to the firing assembly 420, because the knife actuating bar 444, when confined to its normal position, prevents proper engagement of the SULU 418 with the firing assembly 420.


For similar reasons, if the firing assembly 420 and the SULU 418 are engaged to form a single disposable unit, the SULU 418 cannot be disengaged from the firing assembly 420 once mounted in the channel member 22, because the knife actuating bar 444, when confined to its normal portion, prevents release of the SULU 418 from the firing assembly 420.


In another embodiment illustrated in FIGS. 37A-37J, a rotary knob 570 is removably coupled to the channel member 522. As shown in FIG. 37B, the rotary knob 570 includes an H-shaped base 572, a grip member 574 extending upwardly from an upper surface 576 of the H-shaped base 572, and a distal member 578 extending downwardly from a lower surface 579 of the base 572. The base 572 includes longitudinal side walls 572a and 572c, each defining a length which is greater than the width “w” of the channel member 522, i.e., the lateral distance between the sidewalls 582 of the channel member 522. The base 572 also includes front and rear walls 572b and 572d each defining a length which is less than the width “w” of the channel member 522.


The channel member 522 defines a pair of slots 580 symmetrically arranged on the sidewalls 582 of the channel member 522. The slots 580 are dimensioned to receive a portion of the base 572 of the rotary knob 570. The slots 580 are defined on the sidewalls 582 of the channel member 522 at a position immediately above the area 560 at which the proximal end of the SULU 528 and the distal end of the firing assembly 520 become engaged, as shown in FIG. 37A.


The rotary member 570 is movable from an unlocked position to a locked position within the channel member 522 as illustrated in FIGS. 37C-E. In the unlocked position (FIGS. 37C-E), the sidewalls 572a, 572c of the base 572 of rotary member 570 are laterally aligned with the slots 580, and the front and rear walls 572b and 572d extend across the lateral space defined between the sidewalls 582 of the channel member 522. Rotation of the grip member 574 of rotary member 570 effects corresponding rotation of the rotary member 570 within the channel member 522. As the rotary member 570 is rotated from the unlocked position to the locked position (FIGS. 37F-H), the sidewalls 572a, 572c move from a position aligned with slots 580 to a position transverse to slots 580.



FIGS. 37F-H illustrate the rotary member 570 in the locked position, which is rotated about 90 degrees from the unlocked position. In the locked position, the sidewalls 572a and 572c of the base 572 extend across the lateral space defined between the pair of sidewalls 582 of the channel member 522, such that the front and rear walls 572b and 572d are positioned within the slots 580. In this position, the rotary member 570 is locked within channel member 522. The rotary member 570 is rotatable about 90 degrees to transition the rotary member 570 back to the unlocked position.


In use, to secure the SULU 518 and the firing assembly 520 within the channel member 522, a clinician first engages the SULU 518 with the firing assembly 520 to form a single disposable unit. Next, the clinician positions the single disposable unit into the channel member 522, such that the engagement area 560 (FIG. 37A) between the SULU 518 and the firing assembly 520 is placed immediately beneath the pair of slots 580 defined in the channel member 522. Then, the clinician positions the rotary knob 570 above the channel member 522 in a manner such that the base 572 is parallel to the bottom surface 526 of the channel member 522 as illustrated in FIGS. 37I-J. Next, the clinician moves the rotary knob 570 downwardly, in the direction indicated by arrow “G” in FIG. 37I, into the channel member 522, until the rotary knob 570 reaches its unlocked position relative to the slots 580, as illustrated in FIG. 37C. The clinician then rotates the rotary knob 570 to its locked position as illustrated in FIG. 37F to lock the rotary knob 570 within the slots 580.


When the rotary knob 570 is in the locked position, the rotary knob 570 sits atop the upper surface of each of the SULU 518 and the firing assembly 520, and the distal member 578 of the rotary knob 570 abuts the proximal end of the SULU 518 as well as the distal end of the firing assembly 520. As such, when the rotary knob 570 is rotated to the locked position, the rotary knob 570, via engagement with the slots 580, secures the SULU 518 and the firing assembly 520 within the channel member 522.


Alternatively, the clinician may introduce the SULU 518 and the firing assembly 520 into the channel member 522 separately, and subsequently mount the rotary knob 570 in the channel member 522 to secure the SULU 518 and firing assembly 520 in the channel member 522.


To unload the SULU 518 and the firing assembly 520 from the channel member 522, the clinician rotates the rotary knob 570 to its unlocked position, and then lifts the rotary knob 570 upwardly from the channel member 522. The clinician may then remove the SULU 518 and the firing assembly 520 from the channel member 22, either as a single unit or separately.


In the methods of installing and uninstalling the SULU 518 and the firing assembly 520 described above, if the rotary knob 570 is rotated to the locked position before introducing the SULU 518 into the channel member 522, the rotary knob 570 will prevent subsequent entry of the SULU 518 into the channel member 522.


In an alternative embodiment illustrated in FIGS. 38A-38C, firing assembly 620 has a stationary housing 626 including distal end 621 configured to receive a proximal end 619 of a SULU 618. The distal end 621 of the stationary housing 626 defines an elongated longitudinal slot 670 that is dimensioned to accommodate a spring-loaded switch 672 which is slidable through the slot 670. The switch 672 protrudes laterally across the slot 670 and extends both inwardly and outwardly beyond the sidewall 664 of the stationary housing 626 of the firing assembly 620. The SULU 618 defines a detent 680 on its sidewall 682 at the proximal end 619 thereof. The detent 680 is dimensioned to receive and releasably engage an inner surface of the switch 672.


In the absence of any external force, the spring-loaded switch 672 is positioned at the proximal end 670a of the slot 670. In order to secure the SULU 618 to the firing assembly 620, prior to the proximal end 619 of the SULU 618 being positioned within the distal end 621 of the firing assembly 620, the switch 672 must be moved along the length of the slot 670 to the distal end 670b of the slot 670. When the switch 672 is positioned in the distal end of slot 670, the detent 680 is positioned to receive switch 672. In this position, the inner surface of the switch 672 can be slid into the detent 680 formed on the SULU 618. When the inner surface of the switch 672 is received within the detent 680, the proximal end 619 of the SULU 618 is secured to the distal end 621 of the firing assembly 620 and the switch 672 is retained in the distal end of slot 670.


The channel member 622 also defines a depression 624 on an inner face of a sidewall 626 thereof. The depression 624 is dimensioned to receive the switch 672 when the switch 672 is in the distal end of the slot 670.


Due to the above configuration, to position the firing assembly 620 in the channel member 622, the firing assembly 620 and the SULU 618 must be secured together first, before the SULU 618 and firing assembly 620 can be inserted into the channel member 622. If the firing assembly 620 is introduced into the channel assembly 622 without first being engaged with the SULU 618, the switch 672, which would be in its normal proximal position, would be misaligned with the depression 624 in the channel member 622, and, thus, would be prevented from being received within the channel 622.


It will be understood that various modifications may be made to the embodiments of the surgical fastener applying apparatus disclosed herein. Therefore, the above description should not be construed as limiting, but merely as exemplifications of embodiments. Those skilled in the art will envision other modifications within the scope and spirit of the present disclosure.
