されている。[Conventional Clamping Technique] As is well known, the flexible tube that constitutes the main body of the long insertion part of the endoscope that is pushed into the examination area is clamped in order from the inside.
ii" - A flex called a helical l'i which is made by winding a fall plate in a spiral shape, and a braid called a net pipe which is coated on this flex and is made of thin metal wires or braided thin metal wires and synthetic fibers, etc. The blade is made of an outer skin made of synthetic resin attached to the blade.In other words, it is made of a flexible flex that can be bent freely, and a blade that is tightly coated on the outer surface of the flex to prevent the flex from stretching. A flexible tube member is formed, and the outer surface of the flexible tube member is coated with a synthetic resin outer skin that smooths the surface of the flexible tube and prevents body fluids and other limbs from entering the flexible tube. It is structured.

腔内への神人性が悪くなるという欠点を有している。[Problems to be Solved by the Invention]However, the urethane-based elastomer conventionally used for the outer skin has a 44-t resistance that is not very good. Therefore, when an endoscope is sterilized by high temperature sterilization after use, there is a problem that the flexible tube itself becomes less flexible and softer due to the deterioration of this urethane-based elastomer. This has the disadvantage that the repulsive force of the flexible tube is also reduced, and the ability of the flexible tube to enter the lumen becomes worse.
