A clip applying apparatus is described for applying clips seriatim to tissue. The apparatus includes a lockout member for limiting distal movement of the camming member after the proximal-most clip has been applied to tissue. In one embodiment, the apparatus includes a jaw locking member for preventing approximation of the jaw members of the apparatus. In one embodiment, a latch assembly is provided to releasably engage a clip pusher of the apparatus to the camming member of the apparatus.
1. An apparatus for applying surgical clips, comprising: a body portion;a pair of jaw members extending distally from the body portion;a clip stack housed within the body portion and including a distal-most clip;a clip pusher movably positioned within the body portion to advance the distal-most clip
1. An apparatus for applying surgical clips, comprising: a body portion;a pair of jaw members extending distally from the body portion;a clip stack housed within the body portion and including a distal-most clip;a clip pusher movably positioned within the body portion to advance the distal-most clip from the clip stack to a position between the pair of jaw members;a camming member movably positioned within the body portion to approximate the pair of jaw members to form the distal-most clip positioned between the pair of jaw members;a lockout member including a central body portion defining a recess, the lockout member being movable from a first position in slidable relation to the camming member to a second position interlocked with the camming member such that the lockout member and the camming member move in unison with one another; anda stop member configured to abut the recess of the lockout member to limit distal movement of the camming member while the lockout member is in the second position. 2. The apparatus according to claim 1, wherein the lockout member includes at least one flexible leg having a projection and the camming member includes at least one slot dimensioned to receive the projection to interlock the lockout member to the camming member. 3. The apparatus according to claim 2, wherein the at least one flexible leg includes a pair of flexible legs and the at least one slot includes a pair of slots. 4. The apparatus according to claim 2, further including a clip follower operable to urge the clip stack distally towards the pair of jaw members, the clip follower including a tab, the lockout member including an engagement member that extends distally from a distal end of the lockout member, the tab of the clip follower being movable into the engagement member to move the lockout member from the first position to the second position. 5. The apparatus according to claim 4, wherein while the lockout member is disposed in the second position, the lockout member and the camming member are positioned to simultaneously move distally. 6. The apparatus according to claim 1, wherein the lockout member includes a resilient finger positioned to releasably retain the lockout member in the first position. 7. The apparatus according to claim 6, wherein the body portion further includes a separator plate, the separator plate defining an opening dimensioned to receive a portion of the resilient finger of the lockout member. 8. The apparatus according to claim 1, further including a clip follower operable to urge the clip stack distally towards the pair of jaw members, the lockout member including at least one flexible leg having a projection, the camming member including at least one slot, and the clip follower including at least one tab that is movable into an engagement member that extends distally from a central body portion of the lockout member, wherein engagement of the at least one tab with the engagement member moves the lockout member to the second position so that the projection of the at least one flexible leg is received by the at least one slot of the camming member to interlock the lockout member to the camming member. 9. The apparatus according to claim 1, wherein the lockout member defines a plane in the first position, the lockout member being movable along and remaining within the plane as the lockout member moves from the first position to the second position. 10. An apparatus for applying surgical clips, comprising: a handle portion including at least one movable handle;a body portion including a clip pusher and a camming member, the clip pusher being movably supported within the body portion to advance a distal-most clip of a clip stack to a position between a pair of jaw members supported at a distal end of the body portion, the camming member being movably supported within the body portion for movement from a retracted position to an advanced position to approximate the pair of jaw members; anda latch assembly supported on the clip pusher, the latch assembly including a pivotal latch member that is movable from a first position to engage an abutment supported on the camming member to a second position to disengage from the abutment of the camming member;wherein the camming member is operably connected to the at least one movable handle such that movement of the at least one movable handle through an actuation stroke effectuates movement of the camming member from the advanced position to the retracted position. 11. The apparatus according to claim 10, wherein the pivotal latch member is urged towards the first position by a biasing member such that movement of the camming member from the retracted position to the advanced position initially effectuates advancement of the clip pusher. 12. The apparatus according to claim 11, further including a latch cam fixedly supported on the body portion, the latch cam being positioned to engage the pivotal latch member after the clip pusher advances the distal-most clip of the clip stack to the position between the pair of jaw members to disengage the latch member from the abutment of the camming member. 13. The apparatus according to claim 12, further including a biasing member positioned to urge the clip pusher to a retracted position after the latch member is disengaged from the abutment of the camming member. 14. The apparatus according to claim 13, wherein the body portion includes a housing body and a housing cover, the latch cam being supported on the housing cover. 15. The apparatus according to claim 10, wherein the handle portion includes a yoke that is connected to a proximal end of the camming member, the at least one moveable handle being operably connected to the yoke by at least one front link such that movement of the at least one moveable handle through an actuation stroke effectuates advancement of the yoke and the camming member. 16. The apparatus according to claim 15, wherein the at least one moveable handle of the handle portion includes a pair of handles, each of the pair of handles being operably connected to the yoke by the at least one front link. 17. The apparatus according to claim 16, further including a pair of rear links, each of the rear links having a first end pivotally connected to a respective front link by a first pivot member and a second end pivotally connected to the handle portion by a second pivot member. 18. The apparatus according to claim 17, wherein each of the pair of handles defines a cam channel for slidably receiving a respective one of the first pivot members. 19. An apparatus for applying surgical clips, comprising: a handle portion;a body portion extending distally from the handle portion; anda jaw body supported at a distal end of the body portion, the jaw body including first and second jaw members movable from a spaced position to an approximated position;wherein the body portion includes a camming member movable from a retracted position to an advanced position to effectuate movement of the first and second jaw members from the spaced position to the approximated position, the body portion further including a resilient jaw locking member removably positioned between the first and second jaw members to prevent the first and second jaw members from moving from the spaced position to the approximated position. 20. The apparatus according to claim 19, wherein the resilient jaw locking member is a resilient plate and the jaw body includes a pair of inwardly deformable legs, each of the pair of inwardly deformable legs supporting one of the first or second jaw members, the resilient jaw locking member being disposed between the pair of inwardly deformable legs of the jaw body while unactuated. 21. The apparatus according to claim 20, wherein a distal end of the camming member is slidably positioned about the pair of inwardly deformable legs of the jaw body and is movable from the retracted position to the advanced position to move the resilient jaw locking member from between the pair of inwardly deformable legs of the jaw body and to effectuate movement of the first and second jaw members to the approximated position.
