The cervical dilator is mainly used in performing examinations, surgeries, and placing and removing IUDs.
1. Examination: If a woman needs to have an examination of the reproductive cavity or fallopian tubes, such as endoscopy or tubal flushing examination, she needs to use a cervical dilator to facilitate the smooth passage of instruments through the cervix.
2. Surgery: If some gynecological surgery is needed, such as abortion, induction of labor or diagnostic curettage, etc., cervical dilatation rods are needed to dilate the cervix.
3. Placement and removal of intrauterine device (IUD): If the IUD needs to be placed and removed, it is also necessary to use the cervical dilator to facilitate the operation.
