Abstract
An instrument for use in endoscopic surgery is provided. The instrument has a reusable shaft to which a disposable working tip can be removably attached. The disposable working tip has a working surface for providing hemostasis at an auto-regulated temperature. The working surface may include a tapered edge for providing thermally-enhanced cutting and a non-stick coating for operating the instrument at low auto-regulation temperatures. The instrument is capable of being used for a wide variety of endoscopic surgical procedures.
