Endoscopic surgical instrument having a rotational actuator
First Claim
1. An endoscopic clip applier, comprising:
- a flexible tube having a proximal end and a distal end, said flexible tube being flexible enough to pass through a tortuous path of a lumen of an endoscope;
a clip dispenser coupled to said distal end and containing a plurality of clips;
an actuator coupled to said proximal end; and
a control member extending through said flexible tube from said proximal end to said distal end, said control member coupled to said clip dispenser and to said actuator, whereinsaid actuator has a rotatable member for rotating said control member, said rotatable member being arranged such that one complete revolution of said rotatable member causes exactly one clip to be dispensed.

Abstract
A flexible endoscopic clip applier includes a flexible coil with a manual actuator coupled to one end and a jaw assembly coupled to the other end. A store of clips is arranged adjacent to the jaw assembly and a clip pusher is arranged 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 the 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 distal portion. The threaded portion engages a threaded member near the pusher and is coupled to the pusher such that rotation of the threaded control member by the crank causes the pusher to be moved distally.
