Abstract
A bipolar high frequency treatment tool includes an inserting portion to be inserted into a human body through an instrument channel of the endoscope. An electrode assembly is attached to the distal end of the inserting portion. The electrode assembly includes a supporting member having a slit, a pair of shafts held by the supporting member so as to cross the slit, and a pair of electrodes. The pair of electrodes is pivotably supported by the pair of shafts so as to open and close like a pair of pincers. An insulator block is located in the slit between the pair of electrodes to prevent the pair of electrodes from making a short circuit within the slit. The pair of shafts is pressed into the insulating block so that the shafts do not come of from the insulating block and hence from the supporting member.
