Description

Technical Field

[0001] The invention relates to the technical field of pancreatic drainage, and in particular to a pancreatic drainage device for hepatobiliary surgery. Background Art

[0002] In the field of modern medicine, hepatobiliary surgery is a complex and critical type of surgical operation. With the continuous advancement of medical technology, the requirements for the safety and effectiveness of surgery are becoming increasingly higher. In hepatobiliary surgery, the importance of pancreatic drainage devices has become increasingly prominent. When patients with hepatobiliary diseases undergo surgical treatment, the operation may have a certain impact on the pancreas due to the close physiological connection between the liver, gallbladder and pancreas. For example, in some hepatobiliary tumor resection operations, in order to completely remove the diseased tissue, it may be necessary to separate and operate the surrounding pancreatic tissue to a certain extent, which can easily lead to damage to the pancreatic tissue and cause abnormal pancreatic juice secretion. If the pancreatic juice cannot be drained out in a timely and effective manner, the pancreatic juice may accumulate at the surgical site, increasing the risk of infection and seriously affecting the patient's postoperative recovery.

[0003] In conventional drainage devices, the diameter of the drainage tube is generally small, which is easily blocked by viscous pancreatic juice or tissue fragments, affecting the drainage effect and causing incomplete drainage. Secondly, in pancreatic drainage, the drainage pipe is often directly connected to the connecting tube, and the drainage bag is directly connected to the connecting tube, and the connecting tube and the drainage bag are directly placed outside. However, the connecting tube and the drainage bag are both made of soft materials, so when in use, the connecting tube may be squeezed and blocked, and many drainage bags are directly hung on the edge of the bed or on the infusion stand, which are easily squeezed. Therefore, whether it is the squeezing and blocking of the connecting tube or the squeezing of the drainage bag, it brings inconvenience to the use of the drainage device. Summary of the invention
