    Abstract: The present disclosure seeks to provide a handpiece configuration for a surgical instrument such as an electrosurgical instrument to reduce the risk of a burn to the operator handling the handpiece. In particular, the present disclosure firstly provides an inner moulding in the handpiece for housing a motor and a suction path of the electrosurgical instrument. The inner moulding comprises a thermal conduction path between the motor and the suction path for the purpose of transferring heat generated from the motor to the exiting irrigation fluid in the suction path. The handpiece is further configured to comprise a thermally insulating outer casing surrounding the inner moulding. This configuration of the handpiece enables heat transfer from the motor to the irrigation fluid in the suction path while keeping the external surface of the handpiece cool.

    Abstract: An electrosurgical resector tool for cutting, coagulating and ablating biological tissue. The tool has an instrument tip comprising first and second jaws; wherein the second jaw is movable relative to the first jaw between a closed and open position. The first jaw comprises a first pair of electrodes electrically isolated from one another, the first pair of electrodes comprising an inner and outer electrode, and the second jaw comprising a single electrode. The first pair of electrodes is operable as active and return electrodes for delivering RF EM energy, and the single electrode is operable as an active electrode when the inner electrode of the first jaw is operable as a return electrode, or as a return electrode when the inner electrode of the first jaw is operable as an active electrode. The instrument tip is also operable as a microwave field emitting structure for emitting microwave EM energy.
