<p>A polyolefin sheath (30) for the coiled wire housing (12) for an actuating wire (14) of a medical instrument such as forceps (24), (26), (28) associated with an endoscope (10) or the like. More specifically, the present invention involves the use of a polyolefin sheath (30) for the coiled wire housing (12) and O-ring seal (32) of silicone associated with the forceps and a supporting housing (16) in an endoscope (10) to eliminate migration of contaminants into the forked end of the housing (16) which supports the pivotal forceps (24), (26), (28) and preventing entry of contaminants between the convolutions of the coiled wire housing (12).</p> |
