[0002] Paracentesis and drainage is a commonly used diagnostic and treatment method in clinical practice. It is a process of puncturing and placing a drainage tube under the guidance of B-ultrasound or CT to drain the accumulated fluid. If the patient has abdominal bleeding caused by trauma, fluid accumulation after abdominal surgery, acute pancreatitis, intra-abdominal abscess, gastrointestinal perforation, ascites in the late stage of liver cirrhosis, abdominal tumors, etc., abdominal puncture and drainage can help with diagnosis. It can also promote the discharge of pus and ascites, thereby alleviating the symptoms of intra-abdominal hypertension, and has a certain therapeutic effect on the disease.

[0003] The existing Chinese patent document: CN112755279B discloses a gastrointestinal surgical abdominal cavity puncture drainage device, which provides a resistance in the extension direction of the wound through the elastic pullback force of the spring rod, thereby preventing the wound from further cracking in this direction, thereby achieving the purpose of preventing malignant cracking of the wound;
