<P>PROBLEM TO BE SOLVED: To provide forceps for endoscopes which achieves the function of easily washing a targeted diseased area with a washing solution when distal end pieces of the forceps opening and closing in a beak-shaped manner around a spindle face the targeted diseased area and realizes the spindle reliably fixed in a caulked manner without breaking a solution supply pipe at the assembly. <P>SOLUTION: The solution supply pipes 10, 11 are inserted in a flexible sheath 1 in parallel with operational wires 2. The solution supply pipes 10, 11 pass between the spindles 9 supporting a pair of distal end pieces 3 of the forceps, and the exit 11a is placed ahead of the spindles 9. The part in the neighborhood of the end part of each spindle 9 is formed into a cylindrical shape and is fixed on the distal end supporting frame 4 in a caulked manner. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
