PROBLEM TO BE SOLVED: To provide an endoscope allowing an operator to insert/retract and bend a treatment instrument at the same time or alternately without delay with fingers of both hands and to execute the treatment inside the body cavity securely and in a short period of time by linking minute operation of plural treatment instruments. SOLUTION: Plural instrument inserting channels are formed from an operating part 3 to an insertion portion 2 of the endoscope 1, and an operating ring 31 is mounted on the operating part 3 for operating a treatment instrument top moving mechanism. The treatment instrument top moving mechanism is to raise a treatment instrument 60 inserted into one of the instrument inserting channels. The operating ring 31 is mounted adjacent to the entrances 18 and 19 of the treatment instrument inserting channels formed in the operating part 3. |
