宫内节育环是一种安全、简便、经济、有效的节育方法。国内从1957年开始应用以来,目前大约有50％的育龄妇女放置了宫内节育环。现将我院因不同原因取出的节育环27例进行扫描电镜及能谱分析,介绍如下: 材料与方法 (一)样品的制作: 1.病例来源:带环1至24年共27例,因症取环15例。其中4例是带环出血,11例是带环受孕,非因症取环12例,其中1例是行绝育术,11例是因绝经需取出者。 2.取环方法:均为从阴道用取环钩取出,取环顺利,取环困难者未在分析之内。 3.电镜样品制备方法:
IUD is a safe, easy, economical and effective method of birth control. Since the domestic application began in 1957, about 50% of women of childbearing age have placed intrauterine contraceptive rings. Now I hospital for different reasons out of the 27 cases of birth control ring scanning electron microscopy and energy spectrum analysis, described as follows: Materials and methods (a) sample preparation: 1. Case Source: 1 to 24 years with a total of 27 cases, 15 cases of ring disease. Among them, 4 cases had band bleeding, 11 cases had band-ring conception, and 12 cases had non-predominant ring closure. One case was sterilization and 11 cases were due to menopause. 2. Take the ring method: both from the vagina with a hook to take out, take the ring smooth, take the ring are not within the analysis of the difficulties. 3. Electron microscopy sample preparation method:
