<P>PROBLEM TO BE SOLVED: To provide a bipolar type high frequency incision device for an endoscope can smoothly incise a mucous membrane or the like matched with the closing operation of beak-like electrodes. <P>SOLUTION: The shape of a pair of beak-like electrodes 4 is formed so that an electrode interval A near the proximal end of the pair of beak-like electrodes 4 is wider than an electrode interval B near the most distal end in the state of opening the pair of beak-like electrodes 4 for 10° from a closed position, or the pair of beak-like electrodes 4 are formed in such a shape that the electrode interval is gradually narrowed from the proximal end side to the distal end side in the closed state. <P>COPYRIGHT: (C)2009,JPO&INPIT |
