ABSTRACT:
The bipolar hemostatic forceps for an endoscope includes an inserting portion to be inserted into a body cavity through the endoscope, first and second electrodes mounted to a distal end of the inserting portion, and an insulator located between the first and second electrodes to insulate the first and second electrodes from each other except at the front portions thereof. The first and second electrodes are movable between an open position and a closed position so as to be able to pinch a bleeding portion between the front portions thereof. The first and second electrodes are supplied with high frequency electric power to generate high frequency current flowing through the bleeding portion pinched therebetween and thereby stop bleeding of that portion. The insulator is formed in a shape that restricts the swinging angles of the first and second electrodes.
