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 defining a ledge; a plurality of surgical clips disposed within the housing; a pair of jaws mounted adjacent a distal end portion of the housing, the jaws being movable between an open spaced-apart condition and a closed approximated condition; a wedge plate reciprocally disposed within the housing, the wedge plate being movable between a distal position where a distal end thereof is disposed between the jaws and a proximal position where the distal end thereof is free from between the jaws; and a lock mechanism slidably supported within the housing and configured to cam over and engage the ledge of the housing when the wedge plate moves from the proximal position to the distal position to maintain the wedge plate in the distal position. |
