宫内节育器(IUD)是我国育龄妇女主要的节育措施.因其安全、有效、简便、经济、可逆而受群众欢迎,今后10～20年内仍将是我国主要的节育措施.IUD 的种类很多,主要分为惰性和活性两大类.惰性 IUD 由不锈钢、医用塑料、硅橡胶等惰性材料制成.如我国的金属单环、节育花、钢塑混合环、麻花环
IUD is the main birth control measure for women of childbearing age in our country, which is welcomed by the public for its safety, efficiency, convenience, economy and reversibility, and will remain the main birth control measure in China in the next 10 ~ 20 years. , Mainly divided into two categories of inert and active inert IUD stainless steel, medical plastic, silicone rubber and other inert materials such as China’s metal single-ring, birth control flowers, steel-plastic hybrid ring,
