ABSTRACT:
A forceps unit for an endoscope is provided. The forceps unit includes a flexible sheath, an operating wire placed inside the flexible sheath to be reciprocable in a direction of an axis of the flexible sheath, a pair of forceps end pieces, and two support shafts rotatably supporting the pair of forceps end pieces, respectively. The two support shafts are swaged and fixed to an end support frame provided to a distal end of the flexible sheath so that the pair of forceps end pieces rotatable around the two support shaft will open and close like a beak when the operating wire is operated back and forth. The forceps unit is further provided with a liquid feed channel that is placed inside the flexible sheath in parallel with the operating wire. In this structure, a distal part of the liquid feed channel is placed to pass between the two support shafts so that an outlet of the liquid feed channel will be placed in front of the two support shafts. An outer end part of each of the two support shafts has a cylindrical shape. Further, the outer end part is swaged to the end support frame.
