ABSTRACT:
The instant invention is a shielded monopolar electrosurgical instrument for use in laparoscopic and the like surgical procedures. The instrument consists of a rigid outer metallic shield which operates as a conductive coaxial shield and is connected to a patient return electrode of an electrosurgical generator. The use of a coaxial shield coupled to the patient return electrode on the outer surface of the instrument eliminates the need for an outer insulative coating. The shield houses a conductive wire positioned through the center of the shield which is coupled to the active lead from the electrosurgical generator. Between the wire and the shield is placed an insulating sleeve. The tip of the instrument is interchangeable and the instrument may be used in conjunction with a form fitting handle providing the surgeon with finger holes in order to apply pressure to the instrument for operation of grasping items when such a tip is employed.
