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.
