An electrosurgical forceps is provided. The electrosurgical forceps includes an end effector including first and second jaw members. One of the first and second jaw members is movable from an open configuration for positioning tissue between the first and second jaw members to a closed configuration for grasping tissue for subsequent electrosurgical treatment thereof. One or more cutting electrodes are positioned on the first and/or second jaw members. The cutting electrode(s) includes one or more piezo-elements that are configured to oscillate at a predetermined frequency when the cutting electrode(s) is energized to sever tissue.
