Problems solved by technology

[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 to extract ascites. However, manual paracentesis is very easy to damage In the tissue near the abdominal cavity, the positioning of the puncture position is inaccurate, which is likely to cause secondary injury to the patient, and when the ascites is extracted, the puncture needle is built into the abdominal cavity, and a slight vibration may cause injury to the patient
