Abstract
A bipolar high frequency treatment tool includes a flexible insulating tube to be inserted through an accessory channel of the endoscope. The insulating tube has a pair of guide channels extending over the length thereof through which a pair of conductive wires is passed. An end effector is attached to a distal end of the insulating tube. The end effector includes a pair of electrodes that opens and closes like a pair of pincers. The pair of electrodes is connected with the pair of wires so that a high frequency power can be supplied to the pair of electrodes.
