Abstract:
PURPOSE: To prevent the flexibility of a curved part from being adversely affected by a channel tube when the channel tube is additively attached to an endoscope.
CONSTITUTION: The channel tube 15 is attached slidably along the axial direction of an endoscope insertion part 3 by plural fixtures 16 and a mouthpiece 22 is provided at the front end of the channel tube 15. On the other hand, a front end guide 17 having a guide hole 21 is freely attachably and detachably fixed to a front end constituting part 6 of the endoscope. The mouthpiece 22 at the front end is brought into press-contact with the guide hole 21 of the front end guide 17 to transfer a treating means 23 to the guide hole 21 by sliding the channel tube 15 forward at the time of inserting the treating means 23 to the front end side of the endoscope; thereafter, this channel tube 15 is retreated from the range of the curved part 5 by sliding the channel tube 15 backward.
