ABSTRACT:
A surgical instrument for applying ligating clips. The instrument is made with as few detachable parts as possible to avoid any possibility that parts may be loosened and fall into the body of the person being operated on. To this end the instrument has a pair of jaws made from one piece of material or permanently joined to each other and a pair of handles which are similarly constructed. When the handles are pivoted toward each other, the motion is converted by a cam and roller or by elastic deformation of a spring member to linear motion of a push rod which impinges on and forces one of the jaw members toward engagement with the other jaw member, thereby squeezing and applying a ligating clip to a blood vessel or to other tissue.
