ENDOSCOPIC SURGICAL CLIP APPLIER WITH LOCK OUT
First Claim
1. An apparatus for application of surgical clips to body tissue, the apparatus comprising:
- a handle assembly including a trigger and a drive bar reciprocally translatable by the trigger upon an actuation thereof; and
a shaft assembly extending distally from the handle assembly and defining a longitudinal axis, the shaft assembly including;
a housing;
a plurality of surgical clips disposed within the housing;
a jaw mounted adjacent a distal end portion of the housing, the jaw being movable between an open spaced-apart condition and a closed approximated condition;
a pusher bar reciprocally disposed within the housing of the shaft assembly, the pusher bar being configured to load a distal-most surgical clip into the jaws during distal movement;
a clip follower slidably supported in the shaft assembly for urging the plurality of surgical clips in a distal direction; and
a clip carrier disposed in the shaft assembly, wherein the clip carrier is configured to retain the plurality of surgical clips and the clip follower;
wherein the clip follower includes a catch extending from a surface thereof, wherein the catch engages the pusher bar following a firing of a last surgical clip and prevents movement of the pusher bar in a proximal direction.
