[0042] Working principle: When the pancreatic duct support drainage tube for pancreatic surgery is used, the insertion port 2 of the drainage tube body 1 is first inserted into the patient's pancreas, and air is inflated into the airbag 13 through the inflation tube 14 to expand the airbag 13 to prevent the end of the drainage tube body 1 close to the insertion port 2 from bending, and to play a supporting role. Then, the two rollers 3 are respectively placed on the sides of the drainage tube body 1, the U-shaped column 5 is aligned with the connecting column 6, and then the clamping column 10 is pressed to compress the spring 9 and drive the clamping column 10 to retract. The U-shaped column 5 is pushed into the installation groove 8, and then the U-shaped column 5 is pushed to slide into the device groove 7. After sliding to a certain position, the clamping column 10 slides out of the installation groove 8 under the elastic force of the spring 9 and is clamped in the corresponding hole 11, thereby driving the two rollers 3 to be squeezed on the outside of the drainage tube body 1. Then the handrail 4 is moved to make the two rollers 3 fit the outer wall of the drainage tube body 1 and roll, thereby squeezing out the blockage in the drainage tube body 1, so that the drainage tube body 1 remains unobstructed and does not affect the discharge of the drainage fluid.

[0043] When sampling, remove the sampling tube cover 16, then pass the needle through the rubber stopper 17 from the sampling tube 15, and then insert it into the drainage tube body 1 for sampling. After sampling, pull out the needle and install the sampling tube cover 16.
