Electrosurgical device

Abstract

A surgical instrument has an end effector on the end of an elongate shaft extending from a handle. The end-effector has different operations, including grasping, cutting, and sealing and/or coagulating tissue, and one operation is controlled by a switch on the handle proximal end upper surface. The switch is connected to the end-effector to deliver a current to a component in the end-effector. The electrical wire assemblies pass through respective pockets/chambers formed within the handle, an electrical connector contained within each chamber for connecting wires extending from electrodes on the end-effector to wires extending through the handle and on connecting to an electrosurgical generator. The pockets provision within which connectors are contained, one per pocket, prevents insulation damage to wires by connectors, as they are contained within the pockets. The pockets provision pockets side-by-side provides large separation between two connectors, so it is hard for liquid to short the connectors.
