Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a gallbladder puncture and drainage device which is easy to fix. Background Art

[0002] With the development of medical science, especially medical devices and minimally invasive surgery, percutaneous transhepatic gallbladder puncture has been widely used in clinical practice. These technologies are mainly used for patients with severe suppurative cholecystitis and severe obstructive cholangitis. They are effective measures to quickly drain the gallbladder, relieve gallbladder tension, and reduce complications such as gallbladder perforation and septic shock.

[0003] Percutaneous transhepatic gallbladder puncture is mainly used for drainage of acute cholecystitis in clinical practice.

[0004] The advantages are that it is operated under local anesthesia, the operation is quick, the drainage purpose can be achieved in a short time, and the tension of the gallbladder can be quickly reduced. However, the disadvantages are: 1. Subsequent operations such as stone removal and lithotripsy cannot be performed, and the patient still needs laparoscopic or open gallbladder surgery after drainage.

[0005] 2. Massive bleeding is the biggest risk. It often occurs during the operation and when the drainage tube is removed. Some of the bleeding is uncontrollable, leading to rapid death of the patient. There are many reports in China. Therefore, it is necessary to provide a gallbladder puncture drainage device that is easy to fix to solve the above technical problems. Summary of the invention
