An apparatus (100) for application of surgical clips (C) to body tissue, the apparatus comprising: an elongate endoscopic shaft assembly (104) extending distally from a handle assembly (102) and defining a longitudinal axis, the shaft assembly 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; a clip carrier (164) disposed in the shaft assembly and defining a clip channel, a plurality of surgical clips (C) slidably disposed within the clip channel of the clip carrier; a pusher bar (156) reciprocally disposed within the housing of the shaft assembly, the pusher bar being configured to load a distal-most surgical clip, of the plurality of surgical clips, into the jaws during each distal advancement of the pusher bar, the pusher bar including a proximally extending catch (156e); a clip follower (166) slidably disposed within the clip channel of the clip carrier and disposed proximally of the plurality of surgical clips, the clip follower includes a lock-out tab (165a) extending from a surface thereof, the lock-out tab defining a window, wherein the window of the lock-out tab receives the catch of the pusher bar following a firing of a final surgical clip thereby preventing movement of the pusher bar in a proximal direction. |
