近年,由于受术者趋于年轻化和少子女,研究探索一种简便、安全、可靠且具有可复性的男性绝育方法,已成为国内外计划生育工作者研究的重要课题。 1983年以来,我们设计一种银质带有尾端的输精管内节育器,在动物实验取得较好效果的基础上应用到临床,并进行取出复通方面的观察。现将结果报告如下: 一、输精管内节育器的设计 节育器长8mm,直径1mm。节育器分体尾两部。体部圆柱状,长5mm,前端椭圆。尾部长3mm,挫成半圆形。节育器为银质,可塑性强,易于弯曲,对人体无毒。 二、输精管内节育器放置 (一)适应症和禁忌症:同输精管结扎术,但对生殖器炎症要求更为严格。
In recent years, due to the tendency of the surgeon to become young and have fewer children, research to explore a simple, safe, reliable and reproducible method of male sterilization has become an important issue for family planning workers at home and abroad. Since 1983, we have designed a silver-ended vas deferens IUD to be used clinically on the basis of better animal experiments and to observe the removal of recanalization. The results are reported as follows: First, the design of vas deferens IUD length 8mm, diameter 1mm. Idiot split tail two. Body cylindrical, long 5mm, front oval. Tail length 3mm, frustrated into a semicircle. IUD for silver, plasticity, easy to bend, non-toxic to humans. Second, the vas deferens IUD placement (a) Indications and contraindications: vas deferens ligation, but the more stringent requirements of genital inflammation.
