The process of removing the IUD includes sterilization, spreading the towel, clamping, removing the IUD, and checking the completeness, which should be operated by a professional physician. 1. Sterilization: ultrasound or X-ray examination should be carried out before the removal of the birth control ring to determine whether it is in the uterine cavity and to be able to know the type of the birth control ring. After taking the truncated position, routinely disinfect the vulva and vagina. 2. Toweling: lay a sterile cavity towel, place a vaginal speculum to fully expose the cervix, and disinfect the vagina and cervical tissues again. 3. Clamping: clamp the anterior lip with cervical forceps for fixation. 4. IUD removal: uterine cavity probe to explore the depth of the uterine cavity, and use cervical dilatation rod to properly dilate the cervical opening, use the IUD hook to remove the IUD, and use the appropriate strength to pull out the IUD, to avoid blind hooking or hooking to the uterine wall, so as to avoid damage to the wall of the uterus. When it is difficult to remove the IUD, it can be removed under ultrasound or hysteroscopy. 5. Check the integrity: check the integrity of the IUD after removal, and if necessary, do ultrasound or X-ray examination for checking.
