Problems solved by technology

When the jaws apply a clamping force that compresses tissue, it is difficult to achieve a large clamping force due to the relatively small size of the jaw assembly
That is, the dimensions make the lever arm between the pivot of the jaw assembly and each jaw tang relatively short, limiting the mechanical leverage of the jaw assembly

Embodiment Construction

[0087] Referring now to FIG. 1 , a flexible endoscopic clip applier 10 according to the present invention has a relatively long flexible coil (or tube) 12 having a proximal end 14 and a distal end 16 . As used herein, the term "proximal" refers to the end closest to the operator, and the term "distal" refers to the end closest to the patient. A manual actuator 18 is coupled with the proximal end 14 of the coil 12 and a pair of jaws 20 is coupled with the distal end 16 of the coil 12 . The coil is preferably a flat coil with a friction reducing outer sheath (not shown). The present invention will be described in detail for each major component working from the proximal end towards the distal end.

[0088] manual actuator

[0089] A first embodiment of a manual actuator is shown in Figures 1-6. A presently preferred embodiment of a manual actuator is shown in Figure 30 -37, which will be described in detail below.

[0090] The manual actuator 18 in Figures 1-6 has 3 cont...

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.

Description

[0001] The present invention is related to a U.S. patent application entitled "Surgical Clip" serial number No. (Attorney Docket #ISD-083) filed on the same date as the present invention, the entirety of which The disclosure is incorporated herein by reference. technical field [0002] The present invention relates broadly to surgical instruments. In particular, the present invention relates to flexible endoscopic instruments for use with endoscopes. More particularly, the present invention relates to a surgical clip applier that is adapted for use endoscopically and that can be used to clamp and / or suture catheters, vessels, and other tissue, immobilize tissue, or attach foreign objects to tissue superior. Background technique [0003] Surgical clamps are commonly used to apply clamping force to catheters, vessels, and other tissue. In addition, surgical clips are particularly useful in replacing sutures or staples to control bleeding of tissue where sutures or staples a...
