Ligating clip applier
First Claim
Patent Images
1. An endoscopic clip applier for forming ligating clips wherein the clips have an apex, the clip applier comprising:
- an actuating mechanism;
an elongated shaft connected to said actuating mechanism and defining a longitudinal axis; and
a pair of jaws connected to said elongated shaft,said jaws remotely actuated by said actuating mechanism, and said jaws maintained at substantially perpendicular angles to said longitudinal axis, wherein the jaws comprise at least one rearward retention groove having a longitudinal axis, the groove sufficiently long and deep to effectively retain the apex of a ligating clip during at least part of the forming process, wherein the longitudinal axis of said rearward retention groove is substantially parallel to said longitudinal axis.

Abstract
A ligating clip applier mechanism having jaws disposed substantially perpendicular to the longitudinal axis of the mechanism. The jaws provide positive rearward retention of a ligating clip. Clips formed with the mechanism have substantially reduced apex gaps and clip gaps. The mechanism provides three degrees of freedom for manipulating tissue or blood vessels.
