Embodiment Construction

[0062]While several variations of the present invention have been illustrated by way of example in particular embodiments, it is apparent that further embodiments could be developed within the spirit and scope of the present invention, or the inventive concept thereof. However, it is to be expressly understood that such modifications and adaptations are within the spirit and scope of the present invention, and are inclusive, but not limited to the following appended claims as set forth.

[0063]FIGS. 1-3, 5, 6 and 11 illustrate a distal end 2 of the articulating steerable clip applier 1. The clip applier 1 is a long, narrow structure with a free distal end 2 adapted for coupling to an end effector, such as a surgical jaw assembly 3, and a proximal end 101 operatively coupled to a user-operated handle 100 (as shown in FIG. 19). The clip applier 1 is composed of a plurality of relatively short articulating members or phalanges 4 that are connected end to end by pivoting links 5 and capab...

Abstract

A long articulating steerable clip applier affixed to a user-operated handle. A surgical jaw assembly is attached to the other end of the clip applier. The clip applier is composed of articulating phalanges that are connected end to end by pivoting links and capable of angulations relative to one another when subjected to a tensile force. Each phalange has opposing s-shaped exterior grooves that form two continuous spiral-shaped channels for holding tension wires once the phalanges are assembled. Multiple tension wires are attached to opposite ends of adjacent phalanges. When each wire is pulled, this tensile force causes the phalanges to pivot at equivalent angles with each other. As each individual phalange pivots by an equivalent angle, the sum of these angles causes the free end of the clip applier to pivot by a large angle or a cascading actuation effect.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Patent Application No. 61 / 321,233 filed on Apr. 6, 2010, the contents of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]This invention relates to a novel articulating steerable clip applier for laparoscopic or endoscopic procedures.BACKGROUND OF INVENTION[0003]Laparoscopic and endoscopic procedures are conducted through a small incision in the skin or natural body orifices.[0004]In order to operate on a given tissue or a blood vessel, surgeons must ligate or occlude blood vessels to prevent patient blood loss. Surgical clip appliers are used in these surgeries for the application of hemostatic clips to ligate vessels. Clip appliers hold a surgical clip in an open position in a pair of specially adapted jaws. Once these jaws, containing clips, are positioned over a vessel, the clip is manually released over the vessel to ligate it. Inaccuracies in movement or fa...
