Abstract

A flexible endoscopic clip applier includes a flexible coil, a manual actuator coupled to one end and a jaw assembly coupled to the other. A store of clips is arranged adjacent to the jaw assembly and a clip pusher adjacent to the store of clips. The actuator includes a lever for opening and closing the jaws, a knob for rotating the jaw assembly, and a crank for dispensing clips. The knob and lever are coupled to a single control member which extends through the coil to a joiner where it is joined to a pair of pull wires coupled to the jaws. The crank is coupled to a second control member which is threaded along a portion. The threaded portion engages a threaded member near the pusher such that rotation of the second control member by the crank causes the pusher to be moved distally.
