Abstract: Surgical instruments are arranged for cutting and cauterizing tissue with a closed-loop wire. An extension/retraction mechanism forces a closed wire loop to constrict upon tissue enclosed by the loop as the loop is retracted and drawn to a smaller size. Simultaneously, as electrical current is passed through the wire loop and further into the tissue, the tissue is resected and cauterized. The closed wire loop is electrically coupled to a remote power source via conductor(s) which cooperate with the extension/retraction mechanisms. The extension/retraction mechanism permits the loop to be extended and retracted as it is adjusted from a first limit position towards a second limit position and respectively back again. Further, the entire instrument is devised to function in cooperation with common laparoscopic port systems. Accordingly, the retraction mechanism permits the closed wire loop to be extended and retracted through a small hollow tube which may be placed in an abdomenal port installed in a surgical process. In the alternative, these devices may be arranged with slight modification to be either bi-polar or monopolar systems.
