[0002] Hepatobiliary surgery focuses on serious diseases that threaten the health of the Chinese population, such as hepatocellular carcinoma, hepatolithiasis, post-hepatitis cirrhosis, and acute liver failure caused by severe hepatitis. Based on the characteristics of hepatobiliary diseases in China, hepatobiliary surgery in China has developed a comprehensive theoretical and technical framework for the surgical treatment of hepatocellular carcinoma, hepatolithiasis, and traumatic bile duct strictures.
[0003] After hepatobiliary surgery, a drainage tube is used to guide the pus, blood, and liquid accumulated between human tissues or in the body cavity to the outside of the body to prevent postoperative infection and affect wound healing. The drainage tube guides harmful liquids in the body into the fluid bag. In the drainage device, a negative pressure suction device is often used to improve the drainage effect. In the existing device, the negative pressure suction device often also bears the task of collecting the collected liquid. When the pressure in the negative pressure device gradually decreases, the collected liquid needs to be drained out before it can be readjusted to ensure the negative pressure. The operation is relatively cumbersome. In addition, in the existing device, the risk of slipping easily occurs due to the smooth surface of the pipe, and it is not easy to observe. Therefore, this application proposes a new drainage device for hepatobiliary surgery to solve the above problems. Utility Model Content

The lower end of the partition bar 14 does not abut the lower inner wall of the collection bag 1, and the upper end of the partition bar 2 15 does not abut the upper inner wall of the collection bag 1. The connection between the connecting tube 2 12 and the collection bag 1 is located on the right side of the partition bar 14.

A plurality of scale lines 9 are provided on the side wall of the drainage tube 2. The scale lines 9 are all colored lines. The use of the plurality of drainage holes 8 greatly improves the drainage effect of the device.

[0030] The lower end of the connecting tube 11 is fixedly connected to a guide plate 13, and the lower end of the guide plate 13 extends into the collection bag 1. The lower end position of the guide plate 13 is lower than the upper end position of the partition bar 2 15. When the accumulated liquid enters the position of the connecting tube 11, the accumulated liquid adheres to the guide plate 13, thereby ensuring that the accumulated liquid can flow into the collection bag 1 more stably.
[0031] Working principle: When in use, connect the drainage tube 2 with the connecting tube 11 through the connecting cap 13 to achieve communication between the drainage tube 2 and the collecting bag 1, use the connecting cap 2 19 to connect the connecting tube 2 12 to ensure that the negative pressure suction ball 20 can provide negative pressure for the collecting bag 1, and place the end of the drainage tube 2 with the drainage hole 8 into the position in the patient's body where drainage is required. When the position of the drainage tube 2 is adjusted, observe the position and color of the scale line 9 to facilitate subsequent understanding of whether the drainage tube 2 is slipping off, and press the pressing plate 32 at the same time to use the sliding rod 31 to push the lower ends of the two clamping plates 28 to separate the upper ends of the two clamping plates 28, and slide the outer frame 26 to adjust the position of the outer frame 26. After the position is determined, release the pressing plate 32, and under the action of the clamping spring 30, push the clamping plates 28 on both sides to limit the drainage tube 2, and use the fixing ropes 27 on the left and right sides to wrap around the patient's body, and then use the anti-slip mechanism 10 to lock the drainage tube 2. The position of the bag is fixed, the position of the collecting bag 1 is adjusted, and the collecting bag 1 is fixed on the patient's body with the elastic strap 7, and the negative pressure suction ball 20 is fixed on the elastic strap 7 with the buckle 25 and the hanging rope 24, and the negative pressure suction ball 20 is pressed. The gas in the negative pressure suction ball 20 is discharged to the outside world from the position of the one-way valve 23. After the negative pressure suction ball 20 is released, the pressure in the negative pressure suction ball 20 increases, thereby providing negative pressure for the collecting bag 1. Under the action of negative pressure, the accumulated fluid in the patient's body enters the collecting bag 1 through the port of the drainage tube 2 and the drainage hole 8. When the accumulated fluid enters the position of the connecting tube 11, the accumulated fluid adheres to the guide plate 13, thereby ensuring that the accumulated fluid can flow into the collecting bag 1 more stably. When the accumulated fluid in the collecting bag 1 needs to be discharged, the stop-flow clamp 4 is closed to prevent the accumulated fluid from flowing back. The sealing cap 17 can be opened to guide the accumulated fluid from the collecting bag 1. The backflow of the accumulated fluid can be effectively prevented by the setting of the negative pressure mechanism and the stop-flow clamp 4.
