難しい。Further, Japanese Patent Laid-Open No. 2-57228 discloses that
A mounting tool for mounting the endoscope insertion portion on the insertion portion cover is shown. It is a device that keeps the insertion section cover straight and attaches it. This is an effective method when the insertion portion length is short, as in the case of a sigmoid endoscope, for example. However, as in the case of an endoscope for the large intestine, the insertion length is 1
When the length is about 2 m, the workability is impaired in the case of vertical installation and a large space is required in the case of horizontal installation, and it is difficult to perform smooth work in a hospital.
【0009】そこで、USP4,721,097号のよ
うに、挿入部に曲率を持たせて装着装置のスペースを減
らす工夫が必要である。Therefore, as in USP 4,721,097, it is necessary to devise a method for reducing the space of the mounting device by giving the insertion portion a curvature.

路の配置状態を乱してしまい、内視鏡の挿入が難しくな
る場合があった。Pipe lines for air supply, water supply, suction and the like are arranged in the insert cover. Nothing is described about the positional relationship between the duct and the insertion path of the insertion part when the insertion part cover is set to have a curvature and is set in the mounting device. Depending on this arrangement relationship, the tip of the endoscope inserted into the cover is always inserted in contact with the conduit, so the endoscope insertion part may fall between the conduit and the conduit. In some cases, the arrangement of the duct is disturbed, making it difficult to insert the endoscope.
【0011】カバー式内視鏡の装着に関して、内視鏡を
カバーに装着する際、挿入部と管路との干渉を減らすこ
とにより良好な装着性を得ることも一つの課題になって
いる。With respect to the mounting of the cover-type endoscope, when mounting the endoscope on the cover, it is also an issue to obtain good mounting property by reducing the interference between the insertion portion and the conduit.

(紙面上方)に、硬質で把持部カバー部93が口体部9
2と一体的に設けられ、内視鏡操作部94の把持部95
の把持性を向上させるものがある。Further, as shown in FIG. 11, for example, a hard operating portion fixing mouth portion 92 is attached to the proximal end portion of the insertion portion cover portion 91, and it is rearward from the mouth portion 92 of the cover 91 (above the sheet surface). ) Is hard and the gripper cover portion 93 has the mouth portion 9
2 is provided integrally with the grip portion 95 of the endoscope operation portion 94.
There is one that improves the gripping property of the.
【0013】この把持部カバー部93の手元側端部に

ー部96が取り付けてある。A soft operating portion cover portion 96 for covering the other portions of the operating portion 94 is attached to the proximal end portion of the grip portion cover portion 93.
【0014】しかしながら、前記構成では、把持部カバ

視鏡挿入部97を挿入部カバー部91に挿入する作業が
しずらくなる。However, in the above-mentioned configuration, the grip cover portion 93 extends considerably rearward (above the plane of the drawing) from the mouth portion 92, but the insert portion cover portion 91 and the endoscope insertion portion 9 are provided.
Since the clearance with respect to 7 is small, there is a demand to insert the endoscope insertion portion from a position as close to the rear end of the insertion portion cover portion 91 as possible. With the configuration of the conventional example, it becomes difficult to insert the cover endoscope insertion portion 97 into the insertion portion cover portion 91.

部92を本来の固定位置に戻して固定する必要がある。In order to bring the distal end of the endoscope insertion portion 97 closer to the distal end of the insertion portion cover portion 91, the insertion portion cover portion 91 is soft. For this reason, the mouth portion 92 is set to the original (final)
It is temporarily pulled up further rearward (above the paper surface) from the fixed position so that sufficient tension is applied to the insertion portion cover portion 91 so that the cover and the distal end of the scope come close to each other, and then the mouth portion 92 is returned to the original fixed position. It needs to be returned and fixed.

把持部カバー部93がテーパ状の把持部95に沿って覆
うようになっているので、これ以上口体部92を引き上

れがある。In the conventional structure shown in FIG. 11, since the tapered grip portion cover portion 93 covers the tapered grip portion 95, the mouth portion 92 cannot be further pulled up and is inserted. There is a possibility that the mountability of the unit cover portion 91 may deteriorate.
【0017】このようにカバー式内視鏡は、カバー装着
時に、良好なカバー装着性を得ると共に、カバー装着後

【発明が解決しようとする課題】前記カバーに設けられ
た各管路は、座屈などにより管路がつぶれて機能を損な
ってしまうことを防止するため、ある程度の肉厚にして
適度な剛性を確保する必要がある。The respective pipe lines provided on the cover are made to have a certain degree of wall thickness to have appropriate rigidity in order to prevent the pipe lines from being crushed due to buckling or the like and impairing the function. It is necessary to secure it.
【0019】一方、挿入部カバーの外皮は、外径が10

抗を減少させるために薄肉化するのが望ましい。On the other hand, the outer skin of the insert cover has an outer diameter of 10
Since it has a relatively large diameter of around mm, it is desirable to reduce the thickness in order to reduce the resistance when the endoscope is bent.

部長にもよるが5〜20mm程度になる。As in Japanese Patent Publication No. 2-54734, when air is fed into the insertion section cover in order to mount the endoscope insertion section on the insertion section cover, the thin-walled insertion section cover outer skin extends in the axial direction. The relatively rigid pipe line hardly extends in the axial direction. The difference in elongation between the outer cover of the insertion portion and the duct is about 5 to 20 mm, depending on the length of the insertion portion.

るタイプであっても同様な現象がみられる。When the endoscope insertion portion is inserted into the insertion portion cover, the extended portion of the outer cover is wrinkled toward the distal end side due to the influence of friction between the insertion portion cover and the insertion portion, as shown in FIG. It becomes a state. The wrinkled cover outer skin 83 swells inward, presses the conduit 84, and becomes an obstacle to advance / retreat of the endoscope insertion portion. If the insertion part is forcibly attached, there is a risk that a hole will be opened in the outer skin, and the role of the cover that saves the labor of cleaning is lost. The same phenomenon is observed even in the case of a type that is mounted without using an inflator.
