Abstract
An electrosurgical instrument includes a housing having a shaft attached thereto which defines a longitudinal axis therethrough. The instrument also includes first and second opposing jaw members coupled to the shaft, the first jaw member having a conductive surface and movable relative to the second jaw member. The second jaw member is fixed relative to the shaft and includes an electrode rotatable along the longitudinal axis. The rotatable electrode has a sealing surface and a cutting edge. One or more non-conductive stop members are disposed on the first and/or second jaw members that are dimensioned to control the distance between the electrically conductive surfaces when tissue is held therebetween. The jaw members are connected to an electrosurgical energy source such that the jaw members are capable of conducting energy through tissue held therebetween.
