1.With dual function of diagnosis and surgery. Laparoscopic surgery is performed without opening the abdomen and can clarify the diagnosis of many pelvic or abdominal diseases, such as endometriosis, tubal adhesions and fluid retention, ectopic pregnancy, etc. For those who need treatment, surgery can be performed immediately to avoid the trauma caused by blind opening. Thus, laparoscopic technology has become the preferred diagnostic and treatment method for many gynecological diseases. 2. Laparoscopic surgery is minimally invasive, with little trauma, fast postoperative recovery and less pain. The neurological system, digestive system and immune system are less affected. 3, abdominal wall poke hole replaces abdominal wall incision, avoiding damage to abdominal wall muscles, blood vessels and corresponding nerves, no weakness of abdominal wall and abdominal wall incision hernia after surgery, no scarring of abdominal wall muscles affecting motor function, no numbness of corresponding skin caused by abdominal wall nerve cut. 4, poke hole infection is far less than traditional open incision infection or fat liquefaction and can be almost disregarded. 5, laparoscopic surgery on the abdominal cavity organs disturbance is small, the abdominal cavity filled with carbon dioxide gas, the formation of high-pressure area, to avoid the air and airborne dust bacteria on the abdominal cavity and pollution. The operation is mainly based on electrodesiccation and electrocoagulation, and the blood vessels are first coagulated and then broken, resulting in less bleeding. Thus, the postoperative intestinal function recovers quickly, can eat earlier, and greatly reduces the factors of postoperative intestinal adhesions. 6.The use of general anesthesia, the monitoring is complete, the safety is greatly increased. 7.The patient can get out of bed at an early stage after surgery, and the sleeping posture is not limited, and the patient can turn over at will, which greatly reduces the intensity of accompanying care by family members. 8, the whole procedure can be saved with video data, in case of medical disputes, it can be accessed at any time, which increases the transparency of medical behavior.
