[0002] Hepatobiliary and pancreatic surgery is a type of surgical procedure specifically used to treat diseases of abdominal organs such as the liver, bile duct and pancreas. These operations may involve removing diseased tissue, repairing damaged organs, dealing with stones or performing other therapeutic measures. In hepatobiliary and pancreatic surgery, the abdominal drainage device is a common medical device used to drain blood, lymph and other body fluids from the surgical area to reduce the occurrence of postoperative abdominal fluid accumulation and promote the patient's recovery. This device helps to maintain the cleanliness of the surgical area and prevent the occurrence of infection.
