Claims

[Claims for Utility Model Registration] (1) A plurality of annular joint members at the distal end of the body insertion part of an endoscope are connected so as to be bendable in two intersecting directions, and each of the annular joint members is attached at four locations on the inner surface thereof. A wire insertion ring is protruded, one end of the operating wire inserted through the wire insertion ring is fixed to a distal end fixing member located in front of the annular joint member, and the other end can be pushed and pulled by an operating mechanism provided in the operating section. In the curved part structure of the endoscope body insertion part, the interval between at least one set of adjacent wire insertion rings among the four wire insertion rings described above is set to be larger than 90°, and the wire insertion ring with this large interval is set. A curved part structure of an endoscope insertion part into a body, characterized in that a forceps channel that comes into contact with the inner surface of a joint member is inserted between the blowfish. , (2) Utility model registration In claim 1, the interval between the wire insertion rings through which the forceps channels are inserted is:
The structure of the curved part of the endoscope's insertion part into the body, which is between 2° and 30°.
