<P>PROBLEM TO BE SOLVED: To provide an assisting tool for smoothing attaching work of an endoscope to a hood, wherein the tool does not require a restoring force for widening the inner diameter of the hood and time and effort to cut the tool can be omitted to separate the tool from the endoscope in the inner surface side after the hood is attached. <P>SOLUTION: The assisting tool 10 includes an insertion portion 11, a guiding portion 12 and a ring 13 which are provided from the front end to the base end. The insertion portion 11 consists of a plurality of claws 20 and is inserted into a hood 25. An opened portion 15 is provided on the base end side of the guiding portion 12, is opened to a side and receives the front end of an endoscope 29 to the guiding portion 12. A cylindrical portion 14 consists of the insertion portion 11 and a front end side portion of the guiding portion 12, and is elastically deformed in a circumferential direction so that a separation width of a separation portion 16 can freely change. <P>COPYRIGHT: (C)2012,JPO&INPIT |
