固定式宫内节育器的优点是避孕效果好,脱环率、流血率、腰腹痛等不良反应低。缺点是放环器不能弯曲易放环不到位。缺点改进办法:放置器套管内放入金属探针依据子宫形态弯曲探针后,将套管及探针放入宫腔达宫底取出探针放入节育环固定好节育环。在改良放置技术后,与含铜宫腔型宫内节育器对比固定式宫内节育器在各个方面都明显占优势。是一种非常值得大力推广的宫内节育器。 The advantages of a fixed IUD are good contraception, withdrawal rate, bleeding rate, abdominal pain and other adverse reactions. The disadvantage is that the ring can not bend easy to put the ring is not in place.

After the improved placement technique, IUDs were significantly superior in all aspects compared with intrauterine copper-containing intrauterine devices. Is a very worthwhile promotion of IUD.
