ABSTRACT:
A bipolar push rod assembly is disclosed in conjunction with an endoscopic bipolar cautery scissors instrument. The push rod assembly has two conductive push rods which are substantially covered and insulated from each other by a double lumen flexible sheath. The proximal ends of the push rods are stabilized by an overmolded plastic collar and the distal ends of the push rods are stabilized by a ceramic insulator. The plastic collar is provided with a snap retainer for coupling it to a plastic plug retainer having a pair of spaced apart passages. A pair of female plug adapters are press fit onto the proximal ends of the push rods and are maintained in place by the plug retainer with each adaptor residing in a respective one of the passages. The distal ends of the push rods are swaged approximately 90.degree. in opposite directions. A ceramic insulator is disclosed as a one-piece unit into which the distal ends of the push rods are inserted. Another ceramic insulator is disclosed as a two-piece member which fits around the distal ends of the push rods. A double lumen sealing gasket which interrupts the double lumen sheath is also disclosed.
