ENDOSCOPIC SURGICAL CLIP APPLIER WITH CONNECTOR PLATE
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;
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, the pusher bar being configured to load a distal-most surgical clip into the jaws while the jaws are in the open condition and remain in a distal-most position during an approximation of the jaws;
a wedge plate reciprocally disposed within the housing, the wedge plate being movable between a position where a distal end thereof is disposed in the jaws and a position where the distal end thereof is free from said jaws; and
a connector plate reciprocally disposed within the housing, wherein the connector plate detachably connects to at least one of the pusher bar and the wedge plate during at least a portion of a firing stroke of the apparatus.
