Apparatus For Applying Surgical Clips
First Claim
1. 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 to deform the distal-most clip, 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 having a plurality of stop members, 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;
wherein the camming member has at least one notch;
wherein in a second position, the lockout member has at least one of the stop members being positioned to interface with the at least one notch, the engagement between the at least one stop member and the at least one notch limiting distal movement of the camming member; and
wherein the clip follower actuates the lockout member when the clip follower advances to a predetermined clip in the clip stack.

Abstract
An apparatus for applying surgical clips has a body portion housing a clip stack and a pair of jaws supported at a distal end of the body portion. The body portion includes a camming member, a clip follower and a lockout member having a plurality of stop members. The lockout member is movable from a first position in slidable relation to the camming member to a second position interlocked with the camming member. The camming member has at least one notch, and in a second position the lockout member has at least one of the stop members positioned to interface with the at least one notch. The engagement between the stop member and the notch limits distal movement of the camming member. The clip follower actuates the lockout member when the clip follower advances to a predetermined clip in the clip stack.

13. 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 to deform the distal-most clip, 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 having a plurality of stop members, 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; wherein the camming member has at least one notch; wherein in the second position, the lockout member has at least one of the stop members positioned to interface with the at least notch to limit distal movement of the camming member; wherein the clip follower actuates the lockout member when the clip follower advances to a predetermined clip in the clip stack; wherein the apparatus has a latch assembly supported on the clip pusher, the latch assembly including a pivotal latch member movable from a first position to engage an aperture supported on the clip pusher to load a clip between the jaws to a second position, the second position to disengage therefrom and retract the clip pusher; and wherein the camming member is operably connected to a movable handle such that movement of the at least one movable handle through an actuation stroke effects movement of the camming member from the advanced position to the retracted position. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)
