[0027] The effect achieved by the entire embodiment 2 is that, by the action of the soft pad 6 fixedly installed in the sliding sleeve 5, the first drainage branch pipe 3 and the second drainage branch pipe 4 are protected from damage when being squeezed. When the first drainage branch pipe 3 and the second drainage branch pipe 4 need to be added, the connecting block 13 is pulled upward through the handle hole 14. Since the two connecting rods 12 installed at the bottom of the connecting block 13 are movably embedded in the two through holes 10, and a pressure block 8 is installed between the bottoms of the two connecting rods 12, and because a concave seat 9 is installed on the sliding sleeve 5, two compression springs 11 are installed between the top of the inner wall of the concave seat 9 and the top of the pressure block 8, and the outer walls of the two connecting rods 12 are connected to the inside of the two compression springs 11, so that the connecting block 13 is pulled upward. 13, the pressing block 8 can be driven to move upward by a suitable distance, and the two compression springs 11 can be squeezed at the same time, and then the sliding sleeve 5 can be moved to adjust the appropriate length required at the front end of the first drainage branch 3 and the second drainage branch 4, so as to prevent the two drainage branches from being separated by a large interval and the patient from easily touching the two drainage branches, thereby affecting the effect of bile and pancreatic fluid drainage to the body. After moving the appropriate distance, the connecting block 13 is loosened, and under the action of the two compression springs 11, the pressing block 8 is driven to move downward and the first drainage branch 3 and the second drainage branch 4 are limited on the cushion 6.

[0028] Working principle: First, when the patient needs to drain the bile duct and pancreatic duct, the first drainage branch tube 3 and the second drainage branch tube 4 are placed in the bile duct and the pancreatic duct respectively through the digestive endoscope, and then the connecting block 13 is pulled upward through the handle hole 14, and the two connecting rods 12 are driven to move in the two through holes 10, thereby driving the pressing block 8 installed at the bottom of the two connecting rods 12 to move upward. Since two compression springs 11 are installed between the pressing block 8 and the concave seat 9, the two compression springs 11 will be squeezed at the same time. When the sliding sleeve 5 is moved to a suitable position, the connecting block 13 is released. Under the action of the two compression springs 11, it drives the pressing block 8 to move downward, and limits the first drainage branch tube 3 and the second drainage branch tube 4 on the cushion 6. The operation process is simple. The utility model discloses a single structure, which is convenient for doctors or nurses to adjust the separation length of the two drainage branches. Secondly, the main drainage pipe 1 is hollow and has a length of more than 2400 mm. Since a slidable negative pressure device 2 is arranged on the main drainage pipe 1, the bile and pancreatic juice in the patient's body can be drained to the outside of the body along the first drainage branch 3 and the second drainage branch 4 by siphoning or vacuum suction, so as to achieve the purpose of decompression treatment. The whole process does not require the placement of a stent, thus will not cause related complications, and does not require a second operation to remove the stent. Moreover, the double drainage tube effect of the bile duct and the pancreatic duct can be achieved at the same time, and can be directly removed after satisfactory treatment. It not only reduces the risk, time and cost of the patient, but also improves the clinical outcome, thereby improving the use effect of the nasobiliary and pancreatic double drainage tube.
