Two part surgical ligating clip, applicator and method of use

摘要

A surgical clip having first and second separate pieces for ligating a vessel therebetween, an applicator for applying the clip to the vessel, and a method of use thereof. The surgical clip comprises a first tube having a longitudinal slot formed through the outer wall thereof and communicating with a passage extending therethrough for receiving a second tube into the passage of the first tube and circumferentially ligating a vessel positioned in a second channel transverse to and communicating with the first passage. Tangs or projections extend from the outer wall of the first tube about the longitudinal slot thereof and into the passage of the first tube for engaging the walls about a slot in the second tube and securably positioning the second tube in the passage of the first tube. An applicator includes a main housing having a vessel channel for positioning the first tube therein. The vessel channel also includes vessel access openings for transversely positioning a vessel through openings in the first tube outer wall. An insertion mechanism carrying a plurality of second piece tubes slides over the inserted vessel and first tube and securably positions a second tube in the passage of the first piece tube for circumferentially ligating the vessel positioned therebetween.
