A bipolar electrosurgical hook probe includes an end effector that includes first and second electrodes placed in parallel, closely-spaced relationship, each being of a relatively large surface area and a conductive reciprocally movable hook member that is movable into and out of a space between the first and second electrodes. A switch mechanism is provided by which an RF current can alternatively be made to flow between the first and second electrodes during electrocoagulation and from the hook electrode to each of the first and second electrodes when the instrument is operating in its cut mode.
