Abstract:
A bipolar electrosurgical cutting and coagulating probe, comprising:(a) an elongated, tubular barrel having a proximal end, a distal end and a lumen extending therebetween; (b) a handle member affixed to the proximal end of said barrel and including a manually operable actuator member mounted on a surface of the handle member; (c) an end effector affixed to the distal end of said barrel, said end effector comprising: (i) first and second electrodes placed in parallel, closely-spaced relationship, each of a relatively large surface area; (ii) a conductive, reciprocally, longitudinally movable hook member operatively coupled to the actuator member and said hook member having a relatively small surface area compared to the surface areas of the first and second electrodes, the hook member being movable longitudinally in and out of a space between the first and second electrodes upon manipulation of the actuator member; and (d) a plurality of elongated conductors extending through the handle member and into the lumen, one of the conductors connected electrically to the first electrode, another of the conductors connected electrically to the second electrode and still another of the conductors connected electrically to the hook member.
