Description

可视性多功能宫内取环器制造方法及实施该方法的取环器 技术领域
本发明涉及医疗器械领域技术， 特别涉及一种可视性多功能宫内取环器制造方法及 实施该方法的取环器。
背景技术
宫内节育器是一种放置在子宫腔内的避孕装置， 由于初期使用的装置多是环状的， 通常叫节育环。 节育环对全身干扰较少， 作用于局部， 取出后不影响生育， 具有安全、 有效、 可逆、 简便、 经济等优点， 是最常用的节育用具之一。 为了避孕通常在妇女子宫 中放置宫内节育环。 节育环有各种形状， 有圆环、 τ型环、 三角形环， 节育环在宫腔内的 位置和形状各不相同， 放置时间也各不相同， 长的可达 20〜30年， 短的只有 3〜5年， 或 更短； 有的节育环在宫腔内产生嵌顿现象， 摘取非常困难。
现有的摘取宫内节育环器械和装置基本包括两种： 一种是盲视摘取宫内节育环， 盲 视摘取节育环钩是用直径为 3毫米不锈钢丝制作的， 其头部钢丝直径为 1. 3毫米， 有的 半径为 1. 8毫米左右的弯钩， 医生在摘取节育环时， 全凭其经验操作， 由于是盲视， 在 摘取避孕环过程中， 很难找到节育环， 手术时间长， 很容易损伤正常组织， 甚至造成子 宫穿孔， 对于嵌顿比较严重的节育环则难以取出， 需要采取其它手段甚至采用手术， 给 患者带来痛苦。 另一种是可视摘取节育环装置， 虽然是在可视条件下操作， 但取环镜鞘 头部的取环钩设计有缺陷， 取环钩设计在镜鞘的头端部， 由镜鞘本体形成， 主要缺点是 取环钩太靠近头部， 远离内窥镜的视野， 内窥镜根本看不到取环钩， 在手术中看到了节 育环而看不到取环钩， 找不到取环钩和节育环的相对位置， 从而无法实现可视摘取节育 环操作。该可视摘取节育环装置的另一个缺点是取环钩的头部与镜鞘外径在同一高度上， 在手术中很难钩到节育环， 操作很不方便， 难以保证手术的安全性和有效性， 极易损伤 正常组织， 造成手术事故。
