CUTTING AND COAGULATING FORCEPS

摘要

A cutting and coagulating forceps includes a housing (10) with a protruding barrel (14), a pair of electro-cautery jaws (22, 24) which are closed by camming contact with the mouth of the barrel (14) when the jaws are retracted, and an independently movable blade (62) which passes between the jaws. The jaws are opened by squeezing a trigger (36) and the blade is advanced by pressing a lever (60) with the thumb. Forward blade movement is limited by a stop (52) whose position is a function of the jaw position, so that the blade cannot strike the jaws, yet always can travel a distance just short of the jaw tips.
