Then, it is discharged outside through the connecting pipe 72. Note that the forceps hole 26 is connected to the suction tube 74 in the hand operation unit 12. That is, the suction tube 74
Is also used as a treatment instrument insertion tube such as forceps.

FIG. 3 is a perspective view of the chemical solution suction adapter unit 80 used for cleaning the conduit of the endoscope 10. As shown in FIG. The chemical solution suction adapter unit 80 has a first adapter 82, a second adapter 84, and a third adapter 86, and these adapters 82, 84, 86 are three-way switched via tubes 83, 85, 87, respectively. Connected to valve 88. Further, the three-way switching valve 88 is connected to a suction tube 92 connected to a suction device 90 which is permanently installed in the hospital.

The first adapter 82 and the second adapter 84 are adapters which are detachably attached to the end of the distal end hard portion 22 of the endoscope 10 shown in FIG. It has caps 94 and 96 (see FIG. 3). The cap 94 of the first adapter 82 is formed with a through hole 98 communicating with the tube 83, and a plug member 100 is formed to protrude. As shown in FIG. 4, the plug member 100 is fitted to the forceps channel 30 when the cap 94 is fitted to the distal end hard portion 22. Thereby, the forceps channel 30 is closed by the stopper member 100. In this state, the three-way switching valve 8 shown in FIG.

2 through the suction device 90 of FIG. Thereby, the air / water pipe 62 side is switched to the suction side.

The reason why the forceps channel 30 is closed by the plug member 100 is that the air-supply / water-supply pipe 62 has a large pipe resistance due to a small pipe diameter and a resistance due to the nozzle provided at the tip. The reason is big. If the air / water pipe 62 side and the suction pipe 74 side are simultaneously sucked without closing the forceps channel 30 with the plug member 100, the air / water pipe 62 resistance and the nozzle resistance will cause the air / water pipe 62 side to suck. This is because the suction force on the water supply pipe 62 side decreases, and the suction force concentrates on the suction pipe 74 side, which causes a problem that the gas supply / water supply pipe 62 cannot be washed with a chemical solution described later. Thus, when suction is performed on the air / water supply pipe 62 side, the forceps channel 30 is closed, and the suction force is concentrated on the air / water supply pipe 62 side.

In the cap 96 of the second adapter 84 shown in FIG. 3, a through hole 102 communicating with the tube 85 is formed. When the cap 96 is fitted to the distal end hard portion 22 in FIG. 2 and the lever 89 of the three-way switching valve 88 is operated to open the second adapter 84 side in this state, the suction tube 74 shown in FIG. The second adapter 84 communicates with the suction device 90. Thereby, the suction pipe 74 side in FIG. 2 is switched to the suction side. In this state, the suction device 90
Is driven, the air / water supply pipe 62 side and the suction pipe 74 side are simultaneously sucked.
Since the water pipe 62 has a higher pipe line resistance and the like than the suction pipe 74, the suction force can be reduced without using a plug member.
Be concentrated on the side.

The third adapter 86 shown in FIG.
7 is formed with a connection port 106. The connection port 106 is detachably connected to a connection end 72A of the connection pipe 72 protruding from the light guide connector 36 in FIG. In this state, when the lever 89 of the three-way switching valve 88 is operated to open the third adapter 86 side, the connecting pipe 72 shown in FIG. 2 is connected to the suction device 90 of FIG. . Thereby, the connection pipe 72 side is switched to the suction side.
