Methods of laparoscopic operation
Artificial pneumoperitoneum
The skin was cut 1cm at the lower margin of the umbilical wheel, the pneumoperitoneum needle was inserted at 45 degrees from the incision, and a needle tube was connected after no blood was drawn back. If normal saline was flowing smoothly, the puncture was successful and the needle was in the abdominal cavity. Connect with CO2 inflator, the intake speed should not exceed 1L/min, the total amount should be 2-3L. Intraperitoneal pressure does not exceed 2.13KPa (16mmHg).
2. Trocar puncture
The laparoscope needs to be inserted from the cannula into the abdominal cavity. The laparoscopic cannula is thick and the incision should be 1.5cm. Lift up the subumbilical abdominal wall, and slowly insert the trocar into the abdominal cavity in an oblique way and then vertically. When entering the abdominal cavity, the trocar core is pulled out. When hearing the gas burst in the abdominal cavity, insert the laparoscope.
3. Laparoscopic observation
The surgeon held the laparoscope and observed the uterus and ligaments, ovaries and fallopian tubes, and rectum uterus. During observation, the assistant can move and lift the uterine device to change the position of the uterus for examination. If necessary, the suspicious lesion tissue can be sent for pathological examination.
4. Remove the laparoscope
If there is no internal bleeding or organ damage, the laparoscope can be removed, the gas in the abdominal cavity can be discharged, the cannula can be removed, the abdominal incision can be sutured, and the sterile gauze can be covered with and the adhesive tape can be fixed
