防ぐことができない事態が生じることも想定される。Furthermore, many of the conventional sliding tubes for endoscopes of this type have complex structures, so it is practically impractical from an economical point of view to dispose of them after each endoscopic examination. It is possible. Therefore, it must be cleaned and disinfected before reuse, but in this case, sufficient care must be taken in handling to avoid infection between subjects or to the doctor. Even if we take the necessary precautions, it is possible that there may be situations in which we are unable to prevent infection.
従って、従来のこの種の内視鏡用スライディングチュー

検者が苦描をあまり感じないようになる。(Function) With the configuration according to the present invention, the cylindrical structure through which the insertion portion of the endoscope is inserted is made only of plastic material, so that weight reduction is achieved, and the original use of the sliding tube is reduced. Since the thickness of the member can be reduced within a range that does not impair the purpose, the outer diameter of the portion to be inserted into the body cavity of the subject can be made as small as possible. This makes it easier to insert the cylindrical structure into the patient's body cavity by sliding it along the insertion part of the endoscope, and the patient does not feel any discomfort. It becomes like this.
しかも、その筒状構造体の一端又は両端に軟性部材が装

する際、術者乃至被検者の保護上好都合である。Moreover, since the flexible member is attached to one or both ends of the cylindrical structure, it is convenient for protecting the operator or the subject when inserting the cylindrical structure as described above.
（実施例）
第１図は、本発明が適用された一実施例の内視鏡用スラ
イディングチューブの外観を示す斜視図である。(Embodiment) FIG. 1 is a perspective view showing the appearance of a sliding tube for an endoscope according to an embodiment of the present invention.

２を装着したものである。The sliding tube for an endoscope according to this embodiment has a cylindrical structure 1 (see Fig. 2) into which the insertion section of the endoscope is inserted.
is made of polyester resin, and a ring-shaped flexible member 2 made of silicone rubber is attached to both ends of this cylindrical structure 1.
このような筒状構造体１と軟性部材２とを備えた本実施
例の構成であれば、筒状構造体１がポリエステル樹脂製
チューブであるため、軽量化を達成することができる。With the configuration of this embodiment including the cylindrical structure 1 and the flexible member 2, weight reduction can be achieved because the cylindrical structure 1 is a polyester resin tube.

る。Also, set the thickness of this member to 0. Even if the thickness is reduced from 18 mm to about 0.5 mm, the original purpose of the sliding tube for an endoscope can be achieved. That is, the member thickness is 0.
Even if the polyester tube is about 0.5 degrees from the 18th stitch, it is easily bent in the diametrical direction locally as shown by the dotted line in Figure 3, but it is difficult to bend in the axial direction of the tube.
If the subject has a sigmoid colon, a cylindrical structure 1 suitable for straightening the sigmoid colon can be constructed.

がし易く、また被検者が苦痛をあまり感じないようにな
る。When the member thickness of the cylindrical structure 1 is reduced in this way, the outer diameter of the portion inserted into the body cavity of the subject is made as small as possible. Accordingly, when inserting the cylindrical structure 1 into the body cavity of the subject by sliding it along the insertion part 4 of the inner gift 1lt3 as shown by the arrow in FIG. 2, this insertion operation is easy and The subject feels less pain.
しかも、筒状構造体１の両端に軟性部材２が装着されて
いるから、上記のように筒状構造体１を挿入操作する際
、術者乃至被検者の保護上好都合である。Moreover, since the flexible members 2 are attached to both ends of the cylindrical structure 1, this is convenient for protecting the operator or the subject when inserting the cylindrical structure 1 as described above.
なお、筒状構造体１の両端に軟性部材２が装着きれてい

をすることが多く、被検者の危険度が少ないことから、
内視鏡３の挿入部４の挿通元側端のみに軟性部材２を装
着して簡素化することもできる。Note that if the flexible members 2 are not fully attached to both ends of the cylindrical structure 1, the operator is likely to be injured by touching the ends of the cylindrical structure 1, and the risk to the subject is low. Therefore,
It is also possible to simplify the structure by attaching the flexible member 2 only to the end of the insertion portion 4 of the endoscope 3 on the insertion source side.
また、本実施例の如く簡素な構造の場合には、製作容易
