ABSTRACT:
An electrosurgery blade active electrode having a plurality of discrete electrical discharge points along a blade edge. A plurality of distinct points are provided for current discharge, facilitating controlled evenly distributed current through the tissue. The more stable discharge allows cutting with reduced current thus substantially reducing problems of the electrode sticking to the tissue and reducing damage to surrounding tissue. Furthermore, the cutting speed is increased and the smoke generated in the cutting process is decreased with use of the inventive blade. The electrosurgery blade of the invention may also include a plurality of grooves or channels on the side of the blade leading from the blade edge to the back of the blade away from the cutting edge to facilitate the escape of heated gasses from the area of the cut.
