Description

technical field [0001] The invention relates to the technical field of abdominal surgery, in particular to a puncture device for abdominal surgery. Background technique [0002] The abdominal cavity is the cavity between the pelvic cavity and the diaphragm, which mainly plays a role in digestion and absorption. When the human body is cirrhotic, it is very easy to cause hydroperitoneal. A small amount of hydroperitoneal usually does not cause symptoms, but a large amount of hydroperitoneal Ascites can cause abdominal distension and discomfort, and shortness of breath. In some patients with ascites, the joints are swollen due to excessive water. In severe cases of ascites, a puncture of the abdominal wall is required to extract a small amount of ascites samples to determine the cause of the ascites. Usually the collection of ascites is done manually, using a syringe with a puncture needle and a through hole at the bottom to puncture the patient's abdominal wall, and use a hose...
