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 being movable
relative to the second jaw member and the second jaw member being fixed
relative to the shaft having an electrode rotatable along the
longitudinal axis. The rotatable electrode has a sealing surface and a
cutting edge. At least one non-conductive stop member is disposed on at
least one of the first and second jaw members which controls the distance
between the electrically conductive surfaces when tissue is held
therebetween. The jaw member are connected to an electrosurgical energy
source such that the jaw members are capable of conducting energy through
tissue held therebetween.
