Endoscopic surgical clip applier with connector plate

摘要

An apparatus for application of surgical clips to body tissue is provided and includes a handle assembly; a shaft assembly including a housing extending distally from the handle assembly and defining a longitudinal axis; a plurality of surgical clips disposed within the shaft assembly; a jaw mounted adjacent a distal end portion of the shaft assembly, the jaw being movable between an open spaced-apart condition and a closed approximated condition; and a pusher bar reciprocally disposed within the housing of the shaft assembly and being detachably connectable to the housing of the shaft assembly, the pusher bar being configured to load a distal-most surgical clip into the jaws during distal movement and remain connected to the housing of the shaft assembly and in a distally advanced position during an approximation of the jaws.

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; anda connector plate reciprocally disposed within the housing, wherein the connector plate detachably connects to each of the pusher bar and the wedge plate during at least a portion of the firing stoke of the apparatus,wherein the pusher bar and the wedge plate each disconnect from the connector plate following an initial distal movement of each of the pusher bar and the wedge plate.
