ABSTRACT:
A double acting bipolar endoscopic scissors includes a hollow tube with an integral clevis and a bipolar push rod extending therethrough. The tube is rotatably mounted in a handle member which is provided with a manual actuation lever. The bipolar push rod includes a pair of spaced apart rods which are insulated along substantially their entire lengths by polypropylene sheaths, and which are insert molded in a distal insulating collar near their distal ends, in a proximal insulating collar near their proximal ends, and in a plurality of non-conductive cylinders therebetween. The distal collar includes a flattened distal portion and the distal ends of the rods are bent approximately 90 degrees and exit the flattened portion. A pair of scissor blades are mounted in the clevis with an axle screw and a nut and are insulated from the clevis and the axle screw. One of the scissor blades has a ceramic coating on its face to insulate it from the other scissor blade. Proximal tangs of the scissor blades are coupled by links to the bent distal ends of the rods which extend from the flattened portion of the distal collar.
