浄されて、鮮明な観察画像を得ることができる。When introducing the guiding tube 2 into the intestinal tract A, insert the water discharge pipe 14 into the forceps channel from the forceps insertion port 3a, and insert the water discharge pipe 14 into the forceps channel.
The tip of the forceps is made to protrude from the forceps opening 13. Then, the pressurized water discharge unit 15 discharges water into the intestinal tract A through the water discharge pipe 14. That is, water is discharged diagonally backward from the distal end of the water discharge pipe 14 against the inner wall surface of the intestinal tract A, and as a result, the guiding tube 2 receives a propulsive force, and the friction with the inner wall surface of the intestinal tract A is reduced. Not only can the guiding tube 2 be easily and quickly introduced into the intestinal tract A, but also the observation site can be washed with water, allowing a clear observation image to be obtained.

Either the guiding tube 2 is introduced into the intestinal tract A without discharging water according to step 4, or the suction sewage collection unit 7 is turned on by the switch 12 at this time to collect the sewage in the intestinal tract A. That is, a large amount of sewage is generated in the intestinal tract A due to water discharge from the water discharge pipe 14 and water feeding from the water supply tube, but this sewage is discharged from the discharge pipe 1 of the contact member 5 provided at the guide tube insertion port B]. The liquid is sucked into the suction liquid collection unit 7 through the discharge pipe 6 and collected.

とができる。- In the embodiment described in F, the sewage in the intestinal tract A is automatically sucked and collected by the suction sewage collection unit 7.
The sewage in the intestinal tract A can be easily and reliably collected without performing the conventional wiping operation. Therefore,
If you are a scope operator or also collect contamination, you can focus on diagnosis and treatment without having to do time-consuming wiping. At this time, as described above, the protrusion 8C of the contact member prevents liquid 19 from leaking around the guide tube insertion port B from the gap between the inner circumferential surface 8b of the contact member 5 and the guide tube 2, and prevents contamination. It is possible to completely prevent contamination of the surrounding area by liquid. Further, since the operator can collect the final liquid just by turning on the switch 12, the possibility that the operator comes into direct contact with the dirty liquid is reduced, and safety can be improved.

。In addition, by improving the insertability of the guiding tube 2,
Since there is no need to adjust the flexibility of the guiding tube 2 to the skill and experience of the insertion operator, it is possible to standardize and unify the flexibility of the guiding tube 2, reducing the manufacturing cost of the endoscope 1. This also reduces the need for bending the guide tube 2 due to the ease of insertion of the guide tube 2 during the guide tube insertion operation, which reduces the service life of the ankle portion and flexible portion of the guide tube 2. The effect is that it can be extended. In addition, the guiding pipe 2
By improving the insertability of the guide tube 2, there is no need to monitor the guide tube 2 with X-ray fluoroscopy when inserting the guide tube, and
The effect of reducing the amount of radiation exposure can also be obtained.

を省略する。FIG. 4 is an explanatory diagram showing the configuration of an endoscope auxiliary tool according to another embodiment of the present invention. This endoscope auxiliary tool 40 includes a contact member 41 that is fitted into a guiding tube insertion port B into which the guiding tube 2 of the endoscope 1 shown in FIG. 1 is inserted, and the above-described embodiment shown in FIG. It consists of a discharge pipe 42 and a suction finishing liquid collection unit 43 similar to the above. The contact member 4] is made of the same material as the contact member 5 of the above embodiment, and similarly consists of a cylindrical portion 44 and a flange portion 45, but there is a predetermined gap between the inner circumferential surface of the cylindrical portion 44 and the guiding pipe 2. A gap d is provided, and a discharge pipe 46 is formed only inside the flange portion 45. In addition, the flange portion 45
An annular protrusion 47 is formed on the outer side end of the inner peripheral surface of the body. The other points are the same as those of the above embodiment, so the explanation will be omitted.

The tq liquid is sucked and collected by the suction tq liquid recovery unit 43 via the discharge pipe 42 from the discharge pipe 46 of the flange portion. In addition, since the protrusion 47 of the flange portion is pressed against the guide tube 2 in the same manner as the protrusion 8c of the above embodiment, the intestinal tract A
The dirty liquid inside is prevented from leaking around the guide pipe insertion opening B through the gap between the inner circumferential surface of the contact member 41 and the guide pipe 2. Therefore, in this embodiment as well, effects similar to those of the above-mentioned embodiment shown in FIG. 1 can be obtained.
