Abstract
Electric bipolar tweezers include a pair of elongated portions that extend from a base of the tweezers in a forked manner. An electrode is located on the distal end of each electrode. When a legion is held between the elongated portions, high-frequency current is supplied to the electrodes. A perfusate tube is attached to the tweezers and has an outlet that opens near one electrode. A gas line is connected to an intermediate portion of the perfusate tube. Gas is thus mixed with perfusate in the perfusate tube such that perfusate mist is blown from the outlet of the perfusate tube. The mist blows away perfusate between the electrodes, thus preventing the electrodes from short-circuiting.
