1, small abdominal incision, less trauma, beautiful: laparoscopic surgery only requires 3-4 small incisions of 0.5cm-1.5cm in the lower abdomen, 0.5cm incisions do not need to be sutured, the scar is small after healing, non-scar patients can barely see, while the abdominal wall nerves and muscles are not cut, the incision is easy to heal. 2, pelvic and abdominal organs less interference, fast recovery after surgery: laparoscopic surgery without opening the abdominal cavity, less interference with the abdominal organs, the possibility of adhesions after surgery is reduced. The recovery of organ function of laparoscopic surgery is about 24 hours earlier than that of open surgery, and the postoperative hospitalization day can be shortened to 1/2 of the original one. 3. Simultaneous exploration of pelvic and abdominal cavities: When performing gynecological surgery, the rotation of the mirror can simultaneously explore the liver, gallbladder, spleen, stomach and intestines and other abdominal organs, so as to achieve all-round exploration under one anesthesia, make diagnosis and differential diagnosis, and if necessary, jointly implement laparoscopic surgical treatment to achieve twice the result with half the effort. Minimally invasive treatment effect. 4.Shared view of the same screen, facilitating collaboration: surgeons, instrument nurses, anesthesiologists and other operating room staff can share the same monitor, so that the details of the operation can be seen at a glance, facilitating collaborative surgery and improving the success rate and safety of the operation.
