Abstract
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, a latch assembly is provided to releasably engage a clip pusher of the apparatus to the camming member of the apparatus.
Claims12
An apparatus for applying surgical clips comprising:
- a body portion housing a clip stack;
- and
- a pair of jaws supported at a distal end of the body portion;
- the body portion including a clip pusher, a camming member and a clip follower, the clip pusher being movably positioned within the body portion and being operable to advance a distal-most clip from the clip stack to a position between the pair of jaws, the camming member being movably positioned within the body portion and being operable to approximate the pair of jaws in response to direct engagement with the pair of jaws to deform the distal-most clip resulting from a distal movement of the camming member, and the clip follower being positioned proximally of the clip stack and operable to urge the clip stack distally towards the pair of jaws;
- wherein the body portion further includes a lockout member and a stop member, the lockout member including a central body portion defining a recess in a distal end of the central body portion, the lockout member being movable from a first position in slidable relation to the caroming 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, wherein in its second position, the recess of the lockout member abuts the stop member to limit distal movement of the camming member.
