An apparatus (100) for application of surgical clips to body tissue, the apparatus comprising: a handle assembly (102) including a trigger (108) and a drive bar (140) reciprocally translatable by the trigger (108) upon an actuation thereof; and a shaft assembly (104) extending distally from the handle assembly (102) and defining a longitudinal axis, the shaft assembly (104) including: a housing (150); a jaw (106) mounted adjacent a distal end portion of the housing (150), the jaw (106) being movable between an open spaced-apart condition and a closed approximated condition; and a pusher bar (156) reciprocally disposed within the housing (150) of the shaft assembly (104), the pusher bar (156) being configured to load a surgical clip (C) into the jaw (106) during distal movement; characterized in that: a connector plate (174) is reciprocally disposed within the shaft assembly (104), wherein the connector plate (174) is detachably connectable to the pusher bar (156) and operatively connected to the drive bar (140), and wherein the drive bar (140) effectuates movement of the connector plate (174) upon an actuation of the trigger (108); during an initial actuation of the trigger (108), the drive bar (140) is advanced to distally advance the connector plate (174) and the pusher bar (156); and during a further distal movement of the connector plate (174) the connector plate (174) is disconnected from the pusher bar (156). |
