Abstract
A surgical instruments handle, instrument head and forceps assembly for use in, preferably, endoscopic surgery through an endoscopic trocar are disclosed. The handle is contoured so as to provide a receptacle for a plurality of human fingers and a trigger-like extension for another finger as the thumb of the operator is snugly received within a ring of an instrument operator carried by the handle housing. The instrument handle extends to a tubular body of a forceps having first and second cutting members. The handle and forceps assembly may be introduced through an endoscopic locking trocar having a sleeve, having a diameter which is selectively expandable when the trocar is inserted through the abdominal wall into an abdominal cavity, during endoscopic surgery.
