Ligation is required by taking surgery. Female ligation requires ligation of both fallopian tubes so that the egg cannot travel down and the sperm cannot travel up and cannot combine to form a fertilized egg and achieve the purpose of contraception. Under normal circumstances on 3-7 days after a woman’s menstruation or at the same time as a caesarean section, the bilateral fallopian tubes are picked up and folded in the isthmus after running through the sutures, double ligation, cutting the tubes back to back on the line knot, checking that there is no active bleeding can close the abdomen layer by layer, post-operative use of anti-inflammatory drugs to prevent inflammatory infections, after 7 days the stitches can be removed normally, and after half a month it can be healed. Medical technology is more developed, and taking hysteroscopic surgery for ligation causes less damage to the body, less bleeding during surgery, and faster healing after surgery, making ligation surgery easier.
