ABSTRACT:
An improved clip pusher and stop system for a surgical ligator of the type having first and second clip-clamping jaws, a pair of handles to actuate the jaws, a magazine of ligating clips, a pusher track extending to the forward ends of the jaws, a pusher to transfer a clip along the pusher track from the magazine to a forward position between the jaws, and a stop to prevent rearward movement of the clip in the pusher track during the clip-applying and clamping procedure. The improved stop comprises a substantially L-shaped resilient member having a long leg and a short leg. The long stop leg lies along a depression in the first jaw and is affixed near its free end to the first jaw. The short leg extends between the first and second jaws and is receivable in a perforation in the second jaw when the jaws are actuated to clamp a clip. The short leg has an intermediate clip-contacting portion normally extending across the pusher track. The clip-contacting portion is shiftable by an advancing clip out of the pusher track, and returns into the pusher track behind a fully advanced clip to prevent rearward movement of the clip during the clip-applying and clamping procedure and to dislodge the clip from the pusher if adhered thereto by body fluids or the like.
