Surgical resection electrodes use a tungsten heavy metal alloy for construction of the active head, providing long operating time as compared to conventional designs. A bore-through design adds to the stability of the electrode head and provides full electrode ignition very efficiently. Angled branch wire connections enhance visualization of tissues and minimize deterioration of insulation by reducing buildup of concentrated heat. A cavity on the back side of the electrode blocks any discharge from leads insulation at the back side, thus reducing the risk of premature breaking of the lead wires because of sparking.
