Surgical Clip Having Comliant Portion

Abstract

A clip is provided that can be used for ligating tissue, such as vessels, other tubular ducts, and the like. The clip has opposed first and second leg members having proximal and distal ends. The proximal end of each leg member is connected by an apex. The clip has a compliant portion formed on the inner surface of at least one of the first and second leg members. The compliant portion can fill gaps left by springback of the clip after formation.

Description

FIELD OF THE INVENTION[0001]The present invention relates to surgical instruments and in particular to surgical clips and methods used for ligating vessels, other ducts, and the like.BACKGROUND OF THE INVENTION[0002]During many surgical procedures, the surgeon will have to close or ligate various blood vessels and other ducts before severing them in order to prevent excessive bleeding, and reduce the risk of other complications to the patient. One ligation technique is to tie a suture about the vessel to close the vessel. Alternatively, a surgeon can place a clip having a pair of legs connected at their proximal ends about the vessel, and urge or squeeze the legs together to close the vessel.[0003]One drawback associated with some current clips used for ligating vessels is that the legs of the clip may tend to separate to some extent following release from a clip applier. This phenomenon is called duck-billing. Duck-billing can result in insufficient ligation of a vessel, thus leadi...

AI Technical Summary

Benefits of technology

The patent text describes a new design of a ligation clip for use in vessel ligation procedures. The clip has a unique structure that allows it to better withstand the force applied during the closing process and maintains its elasticity. This results in the clip providing better grip and less inflammation during the ligation procedure. Additionally, the clip has a compliant portion on its inner surface that ensures a continuous pressure on the tissue, even after the clip is released. This can improve the efficiency and effectiveness of the ligation procedure.

Problems solved by technology

One drawback associated with some current clips used for ligating vessels is that the legs of the clip may tend to separate to some extent following release from a clip applier.

Duck-billing can result in insufficient ligation of a vessel, thus leading to excessive blood loss and / or unnecessary damage to the vessel.

Further, some known ligation clips are often difficult to preload into a clip applier because of resistance between the tissue disposed between the jaws and the gripping features on the clip legs.
