US Patent 8491625 Apparatus for performing an electrosurgical procedure

An endoscopic forceps is provided. The endoscopic forceps includes a housing having a shaft that extends therefrom. A rotatable sheath operably couples to the shaft and includes a camming member. A drive assembly includes a drive rod that operably couples to the rotatable sheath. An end effector assembly operatively connected to a distal end of the shaft has a pair of first and second jaw members. One of the first and second jaw members is movable relative to the other jaw member. Actuation of the drive assembly causes the drive rod to rotate within the shaft and rotate the rotatable sheath such that the movable jaw member moves from an initial position to a subsequent position.
