Clip ejector for endoscopic clip applier
First Claim
1. An endoscopic clip applier, comprising:
- a flexible coil having a proximal end and a distal end;
a pair of jaws coupled to the distal end of said flexible coil;
a manual actuator coupled to said proximal end of said flexible coil;
at least one clip stored proximal of said jaws;
a clip dispenser located at said clip for pushing said clip into said jaws;
at least one control member coupled to said manual actuator, said jaws, and said clip dispenser such that said manual actuator is operable to open and close said jaws and dispense a clip, whereinsaid flexible coil comprises a proximal coil and a distal coil which are joined to each other by a relatively rigid member, at least a portion of said distal coil being pre-loaded so that when said jaws are closed, said pre-loaded portion is compressed and when said jaws are opened, said pre-loaded portion springs distally.

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.

8. A method for dispensing an endoscopic clip, comprising:
-
delivering an instrument through the tortuous lumen of an endoscope, the instrument including a flexible coil, a pair of jaws coupled to the distal end of the coil, and a clip pusher which pushes a clip into the jaws when the jaws are closed; closing the jaws with sufficient force that at least a distal portion of the flexible coil is compressed and thereby stiffened; pushing a clip into the closed jaws while the distal portion of the coil is stiffened. - View Dependent Claims (9, 10)

11. An endoscopic clip applier, comprising:
-
a flexible coil having a proximal end and a distal end; a pair of jaws located at and coupled to the distal end of said flexible coil; a manual actuator located at and coupled to said proximal end of said flexible coil; at least one clip stored proximal of said jaws; a clip dispenser located at said clip for pushing said clip into said jaws; at least one control member coupled to said manual actuator, said jaws, and said clip dispenser such that said manual actuator is operable to open and close said jaws and dispense a clip, wherein at least a distal portion of said flexible coil is pre-loaded so that when said jaws are closed, said pre-loaded portion is compressed and when said jaws are opened, said pre-loaded portion springs distally. - View Dependent Claims (12, 13, 14, 15)
