With the above structure, first, as shown in FIG. 3, the conduit cover tubes 94 are attached to the conduits 69, 70, 71 of the insertion portion cover 93. Here, the conduit cover tube 94 is in contact with the inner wall of the tip portion 93b of the cover (see FIG. 7). Next, as shown in FIG. 4, the conduit cover tube 94 having the conduits 69, 70 and 71 inserted therein is inserted into the conduit insertion channel 64 of the cover endoscope 92. At this time, the open ends of the conduits 69, 70, 71 are inserted through the channel 64 in a state of being isolated from the channel 64 by the conduit cover tube 94. When the insertion portion cover outer cover 93c covers the endoscope insertion portion 57 together with the insertion, the cover endoscope 92 is attached to the cover 93. Then, the insertion portion 57 is inserted until the tip of the endoscope insertion portion 57 comes into contact with the inner wall of the tip portion 93b of the cover. In the state where the insertion / mounting is completed, the conduit cover tube 94 extends from the opening 63a of the endoscope connector 63. Further, the conduits 69, 70, 71 project from the proximal side opening of the conduit cover tube 94. The conduits 69, 70, 71 are communicated with and connected to the fluid control device 9.

At the time of mounting or removal, the channel expansion air is sent to the insertion section cover part 93 via the expansion tube 36 connected to the expansion device 10.

The light source device 7 and the video processor 8 in the cart 5 are connected to the cover endoscope 92. The endoscope 92 is attached with other covers other than the cover 91 to be watertightly covered. In this way, after the cover and the endoscope are combined as the cover-type endoscope 90, the necessary endoscopic examination is performed.

After the inspection, when the cover endoscope 92 is detached from the insertion portion cover portion 93, first, the air supply conduit 69, the water supply conduit 70, and the suction conduit 71 are removed from the fluid control device 9. Next, the conduit cover tube 94 is slid toward the opening end portions of the air supply conduit 69, the water supply conduit 70, and the suction conduit 71. As a result, the open ends of the respective conduits 69, 70, 71 are covered with the conduit cover tube 94 as shown in FIG. After that, the cover endoscope 92 is removed from the insertion portion cover portion 93. At this time, when the three conduits are removed from the conduit insertion channel 64 of the endoscope, the conduit insertion channel 64 of the endoscope and the opening end of the conduit are separated from each other by the conduit cover tube 94. It is isolated by. Therefore, even if filth that leaks out from the open ends of the respective conduits is not concerned, there is no concern that the conduit insertion channel 64 of the cover endoscope 92 will be contaminated.

Then, only the dirty cover 91 is discarded, and the cover endoscope remains clean. Therefore, the cover endoscope 92 is equipped with a new sterilized cover and is used again for the next floor without cleaning and disinfecting.

In the present embodiment, when the cover endoscope 92 is removed after the inspection is completed, the open ends of the conduits 69, 70, 71 are isolated from the channel 64. Therefore, there is no risk that dirt or the like will leak out from the open ends of the respective pipelines, there is no concern of infection, and it is safe and sanitary. Further, in the present embodiment, it is possible to eliminate the need for cleaning and disinfecting the endoscope, and it is possible to continuously use the endoscope.

In addition, by covering each end of each of the conduits with the conduit cover tube 94 in advance and then inserting the conduit cover tube 94 into the endoscope, dirt or the like adhering to the endoscope may be reversed. No pollution of parts.

In the modified examples shown in FIGS. 7 to 9, the cover endoscope is partly different from the structure of the above-described embodiment. In the above embodiment, the conduit insertion channel 64 communicates with the connector 63, but in the present modification, as shown in FIG. 7, the opening 63a of the conduit insertion channel 64 has the operation portion 55. It is provided in. Further, in this modification, as shown in FIG. 8, a Y-shaped branch pipe 97 is connected to the proximal-side opening end portion 71a of the suction pipe passage 71.

The Y-shaped branch pipe 97 is composed of a branch pipe main body 97a and a tip joining pipe 97b provided at the tip of the branch pipe main body 97a. A hand side suction pipe line 98 is connected to one end of the branch of the branch pipe body 97a. The fluid control device 9 is connected to the proximal end of the proximal suction conduit 98.

A forceps plug 99 is detachably provided in the opening of the branch pipe body 97a. Further, a treatment tool is inserted from the other end of the branch of the branch pipe body 97a.

With the above configuration, the tip joining pipe 97 b of the Y-shaped branch pipe 97 is detachably connected to the proximal opening end 71 a of the suction pipe 71. The endoscopic examination is performed in a state where the Y-shaped branch pipe 97 and the fluid control device 9 are connected.

When the inspection is completed, after sterilizing and further sucking air, the forceps plug 99, the Y-shaped branch pipe 97, and the proximal suction pipe 98 are removed from the suction pipe 71.

The end portion of the Y-shaped branch pipe 97 on the proximal side is wiped off with gauze soaked in rubbing alcohol. This is for the following reason. Since the air is sucked after the sterilization, the insides of the suction pipe 71 and the proximal suction pipe 98 are clean to some extent over the entire length. However, the inside of the suction line 71 may not be sufficiently clean, so that the disinfection is ensured. It is possible to prevent the bacteria from spreading around when the tip confluence pipe 97b comes out of the suction pipe line 71. At this time, it is necessary to take care so that the gauze after disinfection does not come into contact with the tube 94 or the operating portion 57 and contaminate it.

Furthermore, taking care not to touch the suction conduit 71, pick up the proximal side protruding portion of the conduit cover tube 94 with a finger, and as shown in FIG. 9, remove the conduit cover tube 94. The end portion is made to slide from the end surface of the suction pipe line 71 to, for example, about 5 to 30 cm. After the slide, the cover endoscope 92 is removed from the insertion portion cover portion 93.

At the time of removal, the conduit insertion channel 64 of the endoscope and the opening end of the suction conduit 71 are separated by the conduit cover tube 94. Therefore, even if filth that leaks out from the open ends of the respective conduits is not concerned, there is no concern that the interior of the conduit insertion channel 64 of the cover endoscope 92 will be contaminated.

When the pipe tube 94 is pulled out, the tube cover tube 94 may be slightly displaced toward the hand side, but the tube tube 94 covers the suction tube line 71 over a considerable length. Therefore, the tube 94 does not fall out of the suction conduit 71 before the suction conduit 71 comes out of the conduit of the conduit insertion channel 64.

FIG. 10 is a configuration diagram according to a modification of the insertion portion cover portion.

The insertion portion cover portion 96 shown in FIG. 10 does not have the mouth portion 65a, or can be separated from the insertion portion cover outer skin 96a. The insertion portion cover outer skin 96a can be wound around the tip end portion 65b side or the mouth body portion 65a side or can be returned.

As shown in FIG. 10, in the insertion portion cover portion 96, an insertion portion cover outer skin 96a is wound around the tip end portion 65b side in advance. In this state, the conduit cover tube 94 inserted through each of the conduits is inserted and attached to the conduit insertion channel of the cover endoscope 54. Next, by unwinding (returning) the insertion portion cover outer cover 96a, the cover outer cover 96a is attached to the insertion portion 57 of the cover endoscope 54. Conversely, at the time of removal, the insertion portion cover outer cover 96a is wound around the tip end portion 65b side. According to this modification, the cover endoscope 54 can be easily inserted and removed, and the dilator 10 can be omitted. The rest of the configuration, functions and effects are the same as those of the above-mentioned embodiment, and the explanation is omitted.

Further, in each of the above embodiments, the cover endoscope may be an optical fiber endoscope or an ultrasonic endoscope in addition to the electronic endoscope described above, and is not particularly limited. .
