- 摘要：
PROBLEM TO BE SOLVED: To be able to easily fix a treatment tool insertion tube on the mouthpiece of an endoscope in a secured airtight state, and to avoid the occurrence of any drastic change in material hardness of the connection to the mouthpiece or in its vicinity.
SOLUTION: The treatment tool insertion tube 4 is made of a flexible tube 10 with a prescribed thickness. Helical grooves 11 are cut over the external circumferential surface to keep a coil 12 wound around the helical grooves 11. The leading end side of the insertion tube 4 is a region of only the flexible tube 10 where the coil 12 extends. A reinforcement member 14 made of a thin metal pipe is mounted so as to cover the soft portion of the flexible tube 10. The rear part of the reinforcement member 14 passes the edge of soft tube portion and extends beyond the tube position where the coil 12 ends.
