Abstract
A bipolar high frequency treatment tool has an insetting portion to be inserted into a body cavity through an endoscope. Two electrodes are pivotably supported within a slit formed to a supporting member attached to the distal end of the inserting portion. An insulating member is also located within the slit of the supporting member. The insulating block has substantially the same width as the slit. The insulating block has first and second side surfaces which are facing the first and second inner side surfaces of the slit, respectively, and deformed to define first and second spaces between the insulating block and the first and second inner side surfaces of the slit. The first and second electrodes are received in the first and second electrodes, respectively.
