1. Artificial pneumoperitoneum
The skin was cut 1cm at the lower edge of the umbilical wheel, and then a pneumoperitoneum needle was inserted at 45 degrees through the incision, and then a needle tube was inserted after redrawing without blood. If the normal saline was smoothly flowing in, the puncture was successful and the needle was in the abdominal cavity. With CO2 inflator, the inlet speed should not exceed 1L/min, and the total amount should be 2-3l. Intraperitoneal pressure does not exceed 2.13KPa (16mmHg).
2. Trocar puncture
Laparoscopy requires insertion of the cannula into the abdominal cavity. The laparoscopic cannula is thick and the incision should be 1.5cm. Raise the lower abdominal wall of the umbilicus, insert the trocar into the abdominal cavity oblique and then vertically slowly, feel a breakthrough when entering the abdominal cavity, pull out the trocar core, hear the sound of gas in the abdominal cavity, insert the laparoscope, connect the light source, adjust the patient's body position into the head, low hip and high 15 degrees, and continue to slowly inflate.
3. Laparoscopic observation
The surgeon holds the laparoscope and the eyepiece to observe the uterus and ligaments, ovary, fallopian tube and rectum. During the observation, the assistant can move the uterus and change the position of the uterus to cooperate with the examination. If necessary, the suspected lesion should be sent for pathological examination.
4. Remove the laparoscope
No internal bleeding or organ damage was detected before the laparoscope was removed, the gas in the abdominal cavity was discharged, the cannula was removed, the abdominal incision was sutured, and sterile gauze and adhesive were applied for fixation.
