Patent ID: 6969389

Claim:
A bipolar hemostatic forceps for an endoscope, comprising: an inserting portion configured to be inserted into a body cavity through the endoscope; first and second electrodes mounted to a distal end of said inserting portion, said first and second electrodes being movable between an open position and a closed position so as to be able to pinch a bleeding portion between front portions of said first and second electrodes, said open position and closed position defining swinging angles of said first and second electrodes, said first and second electrodes being supplied with high frequency electric power to generate high frequency current flowing through the bleeding portion pinched therebetween; an insulator located between said first and second electrodes to insulate said first and second electrodes from each other except at said front portions, said insulator having a shape that restricts the swinging angles of said first and second electrodes, wherein said insulator includes first and second side surfaces, said first and second side surfaces facing said first and second electrodes, respectively, said first and second side surfaces being provided with first and second protrusions, respectively, said first and second protrusions respectively abutting against said first and second electrodes to restrict the swinging angles of said first and second electrodes; and first and second pins penetrating said insulator through said first and second side surfaces, said first pin pivotably supporting said first electrode in the vicinity of said first side surface, said second pin pivotably supporting said second electrode in the vicinity of said second side surface; wherein said first protrusion of said insulator surrounds said second pin in the vicinity of said first electrode to prevent said first electrode from coming into contact with said second pin, and wherein said second protrusion of said insulator surrounds said first pin in the vicinity of said second electrode to prevent said second electrode from coming into contact with said first pin.
