部材5が直線状態となるようにする必要があった。However, as shown in FIG. 12, when the endoscope 4 is immersed in the ultrasonic cleaning tank 3 for ultrasonic cleaning, the ultrasonic wave is generated because the insertion portion 4b or the universal cord 4c is long. The bending prevention member 5 provided in the connecting portion that connects the operation portion 4a of the endoscope 4 and the insertion portion 4b or the universal cord 4c is curved in the cleaning tank 3 and is in a curved state. Ultrasonic vibration was applied. Therefore, as shown in FIG. 13, the bending prevention member 5, the insertion portion 4b, or the universal cord 4c is used.
The cleaning liquid may enter the operation part due to the reduced contact surface with. Therefore, the bending prevention member 5 and the insertion portion 4b or the universal cord 4c
It was necessary to make the bending preventing member 5 linear so that the cleaning liquid did not enter from the contact surface with.

5. The above-mentioned endoscope 11 and the like are connected, and a plurality of treatment tools 12 are connected to the treatment tool connecting portion 13. Pump 19 in this state
Is operated to deliver the cleaning liquid to the conduits of the treatment tool 12 and the endoscope 11 via the intra-conduit cleaning adapter 15 and the treatment tool connecting portion 13. In addition, the distal end portion 11a of the endoscope 11 and the treatment instrument 1 are immersed in the cleaning liquid filled in the ultrasonic cleaning tank 14.
2 and a treatment instrument connecting portion 1 to which the treatment instrument 12 is connected
The ultrasonic wave transmission device 18 is started in a state where 3 and 3 are immersed. When ultrasonic vibrations are generated in the ultrasonic cleaning tank 14, ultrasonic cleaning of the treatment tool 12 and the endoscope distal end constituting section 11a is started.

るようになっている。As described above, since the ultrasonic cleaning tank 14 is arranged on the washbasin 23, it does not wet the surroundings and the apparatus even if the cleaning liquid overflows. That is, by setting the ultrasonic cleaning tank 14 and other constituent devices and members such as the ultrasonic wave transmitting device 18 and the pump 19 as separate bodies, the installation places of the ultrasonic wave transmitting device 18 and the pump 19 can be freely set. Therefore, each device may be arranged in a place where space is available. Further, since the ultrasonic cleaning tank 14 is a separate body, the size of the ultrasonic cleaning tank 14 can be freely selected according to the installation place and the purpose of use. Further, since the distal end constituting portion 11a of the endoscope 11 is immersed in the cleaning liquid filled in the ultrasonic cleaning tank 14, the bending preventing member 1
The cleaning liquid does not enter from 1b, and the endoscope 11 can be arranged on the washbasin 23 with a margin.

きる。By providing the cleaning device 20 having the liquid supply pump 19 with the air supply pump 19a, dry air can be sent into the conduits of the endoscope 11 and the treatment instrument 12. Therefore, the water in the pipeline can be quickly removed. Further, instead of using the liquid feed pump 19, it is possible to use a structure in which the pressure of tap water is utilized.

It is necessary to prevent the bending preventing member 11b from being bent when the ultrasonic wave is soaked in and is immersed. Therefore, by providing the guide member 14a inside the ultrasonic cleaning tank 14 as shown in FIG. 4, it is possible to prevent the bending prevention member 11b from being curved, so that it is possible to reduce the invasion of the cleaning liquid. ing.

たびたび発生していた。By the way, since the conventional conduit for raising the forceps is designed so that both the conduit on the distal end side and the operating part side communicate with the outside air, when it is inserted into the body cavity for inspection. Since a pressure difference is generated between the pressure inside the body and the pressure outside the body, the filth inside the body cavity enters deep inside the duct to cause contamination of the endoscope. For this reason, the pipe is capped during the inspection, and the cap is removed only when the pipe is washed to send the washing liquid.
However, since the cap is frequently removed and attached, the cap may be removed or the endoscope may be inspected with the cap left unattached, so that the filth is often inserted deep inside the tube.

5 (56) is provided with an O-ring 57. Further, the outlet 52 is connected to the air / water supply button 55 or the suction button 56.
The cap 58 is provided in the vicinity of the above so as to integrally close the button 55 (56) and a cap portion (not shown) to prevent the cap 58 from being lost.
