Abstract
An electrosurgical instrument for performing at least one of sealing and dividing tissue includes a housing having a shaft attached thereto, the shaft defining a longitudinal axis. The electrosurgical instrument also includes a first jaw member movable relative to a second jaw member, the first jaw member attached to the shaft and being relatively movable from a first open position wherein the jaw members are disposed in spaced relation relative to one another to a second closed position wherein the jaw members cooperate to grasp tissue therebetween. The instrument also includes a drive rod assembly for imparting movement of the jaw members between the first and second positions and a rotating assembly attached to the housing for rotating the jaw members about the longitudinal axis. A knife assembly is also attached to the housing for separating tissue grasped between the jaw members and a handle assembly is attached to the housing for actuating the drive rod assembly. The instrument also includes first and second electrical leads which connect the jaw members to a source of electrical energy such that the jaw members are capable of conducting energy through tissue held therebetween. A handswitch is attached to the housing to allow a user to selectively energize the jaw members.
