<P>PROBLEM TO BE SOLVED: To provide an attachment for endoscope, treating tool for endoscope and endoscope system which can be made to selectively function only when using the treating tool for endoscope necessitating rotation regulation of a treating part, and, if not, become the endoscope which is not different from a common endoscope. <P>SOLUTION: The endoscope system 1 has the endoscope 2, the attachment 4 for endoscope which has a non-circular deformed hole 13 communicating to the opening part 5a of the channel 5 of the endoscope 2 and is mounted at the tip 3a of the insertion part 3 of the endoscope 2, and the treating tool 6 for endoscope equipped with a flexible tube 14 and the treating part 16. A projecting/receding part 14d having a non-circular cross section corresponding to the opening shape of the deformed hole 13 is formed at the tip part 14b of the flexible tube 14 and is rotationally regulated by the deformed hole 13. Also, the treating part 16 has a directional property around an axis in relation to the flexible tube 14 and is rotationally regulated. <P>COPYRIGHT: (C)2007,JPO&INPIT |
