ABSTRACT:
A polyolefin sheath for the coiled wire housing for an actuating wire of a medical instrument such as forceps associated with an endoscope or the like. More specifically, the present invention involves the use of a polyolefin sheath for the coiled wire housing and O-ring seal of silicone associated with the forceps and a supporting housing in an endoscope to eliminate migration of contaminants into the forked end of the housing which supports the pivotal forceps and preventing entry of contaminants between the convolutions of the coiled wire housing.
