Abstract
Hermaphroditic biopsy forceps jaws for use in an endoscopic biopsy forceps instrument are made from a flat sheet of stainless steel or other suitable material which is stamped and then progressively formed into a jaw cup having a tang. According to the presently preferred embodiment of the invention, the jaw is provided with two substantially parallel tangs, one being shorter than the other. Both tangs are provided with central mounting holes for mounting the jaw on an axle pin between the arms of a clevis. The longer of the tangs is provided with a hole for coupling it to the distal end of a control wire. The tangs are located such that when the jaws are mounted in the clevis, the short tang of each jaw resides between the two tangs of the other jaw. The stamped jaw of the invention may be provided with or without teeth. The location of the tangs permits the mounting of a knife between the jaws, if desired. Other end effectors of similar construction are also disclosed.
