If the insertion part 2 is pulled outside the body, the treatment target site is collected. Also at this time, the enlarged diameter portion 10A of the coil 10 is locked by abutting against the protrusion 27, and the insertion portion 2 is prevented from falling off.
- the insertion portion can be engaged with the operation portion main body as in the prior art. There is no need to attach a separate member to the housing, and the number of parts can be reduced.
- the manufacturing process of the enlarged diameter portion 10A is easy because the punch 54 is simply pushed into the coil 10 inserted into the die 51. Further, when assembling the biopsy forceps 1 for an endoscope, the coil 10 may be stored in the storage groove 26, so that the assembly is facilitated. Therefore, the manufacturing process can be simplified and the manufacturing cost can be reduced. Also, by forming the enlarged diameter part 10A with a part of the coil 10, it is easy to secure the strength against tension.
- the present invention is not limited to the above-described embodiment, and can be widely applied.
- the method of forming the enlarged diameter portion 10A is not limited to pressing by the punch 54. It is also possible to form parts with different diameters when winding! ,.
- the enlarged diameter portion 10A is not limited to the proximal end portion of the coil 10 as long as it is formed in a portion accommodated in the operation portion 3.
