レントゲン撮影を行う。 After inserting the tip of the endoscope until it reaches the duodenal papilla, insert the catheter 31 through the treatment instrument insertion port 21.
is inserted into the treatment instrument insertion channel 23 and pushed forward until the distal end of the catheter 31 reaches the accommodation chamber 22. Next, when the raising knob 20 is rotated, the treatment instrument guide 19 is raised via the operating wire 35.
At this time, since the distal end of the catheter 31 enters within the observation field of view, it becomes easy to insert the catheter 31 into the duodenal papilla, which is the entrance of the bile duct and pancreatic duct. After inserting the distal end of the catheter 31 into the bile duct or pancreatic duct, the base 4 provided at the proximal end of the catheter 31 is inserted.
A syringe 49 containing a contrast agent is connected to 8, and the contrast agent is injected into the bile duct or pancreatic duct to perform X-ray imaging of the bile duct or pancreatic duct.

1 is moved backward, and its tip is opposed to the cleaning hole 47 of the treatment instrument guide 19. And catheter 3
A syringe 49 containing a cleaning liquid is connected to the nozzle 48 of No. 1, and high-pressure cleaning liquid is supplied. Since the resistance on the inner surface of the catheter 31 is low, the cleaning liquid passes through the cleaning hole 47 facing the opening of the catheter 31 without decreasing its flow rate, and enters the accommodation chamber 22 on the opposite side from the guiding surface of the treatment instrument guide 19. It flows in and washes away the dirt accumulated in the storage chamber 22.

3, and a rising operation is performed. When cleaning the opposite side of the guiding surface of the treatment instrument guide 19, the treatment instrument 31 is removed and the syringe 49 containing the cleaning liquid is connected to send the cleaning liquid.
The cleaning liquid is sent to the storage chamber 22 through the notch 51 for cleaning.

As mentioned above, when the treatment instrument guide installed in the storage chamber is raised, the cleaning device faces near the guide path and communicates the guide path and the guide surface of the treatment tool guide with the storage chamber on the opposite side. Since the hole is provided in the treatment instrument guide, dirt accumulated in the storage chamber on the opposite side of the guide surface of the treatment instrument guide can be easily washed and removed. Further, since cleaning can be performed while the endoscope is inserted into the patient, treatment time can be shortened.
