Abstract

一种泪道阻塞硅胶条嵌入术组合器械,除本手术 常规器械外,其特征是有下鼻道窥镜和导管钩取器。 手术时利用下鼻道窥镜很容易找到导管;利用导管钩 取器,方便导管从鼻道拖引出,使手术操作简化。降 低了对手术条件及施术人员的技术要求,缩短手术时 间,减少治疗费用。

Description

本实用新型涉及一组泪道阻塞硅胶条嵌入术组合器械。
慢性泪囊炎泪道阻塞是一种常见病。其根治方法多采用泪囊摘除、泪囊鼻道吻合、逆行钻孔扩大鼻泪管等。手术器械多只用泪道冲洗针头、泪点扩张针、泪道探针等。这些手术难度较大。均需切开泪囊,在鼻骨上凿孔,术中病人痛苦,术后内眦部留有疤痕,病人必须住院,费用高。近年来有人报导用挂线、插管、硅胶管埋藏、环状硅胶管逆行插管术等,均已取得成功。但是其手术操作复杂,在下鼻道处,导引线不易窥见取出。本实用新型组合器械的目的就在于简化这些手术操作,降低对手术场地、施术人员的技术要求,而手术成功率反而得到提高。
本实用新型组合器械,除常规泪道阻塞硅胶条嵌入手术用器械(泪道冲洗针头、泪点扩张针、泪道探针、麻醉导管硅胶条)外,其特征是使用了下鼻道窥镜(见图5)和麻醉导管钩取器(见图1)。
下面结合附图来介绍这两种新器械的结构及工作原理。
图1是导管钩取器的主视图;
图2是钩取器主要工作部位(图1)的局部放大图;
由图1不难看出,导管钩取器有手柄〔1〕,它一般由塑料制造(也可用金属材料)。手柄〔1〕的一端固结有一段不锈钢管〔2〕,其长短、粗细合适。手柄〔1〕内套有推销〔3〕,推销〔3〕上固结有不锈钢针〔4〕;手柄〔1〕内弹簧〔5〕将推销〔3〕始终推出手柄〔1〕通孔外,钢针〔4〕在钢管〔2〕内通到钢管的前端。由图2可以看出,钢管〔2〕的前端有穿透的斜向孔槽与钢针〔4〕前端部在这里交汇,其方向斜向手柄一方。〔6〕是被钩取物件。
图3、图4是手柄的另外两种结构形式,它们其后都有一悬伸部。在图3手柄悬伸部上铆结有弹簧片〔7〕,图4手柄悬伸部装有杠杆〔8〕,借压簧〔9〕使其复位。
图5是下鼻道窥镜的结构图;
图6是图5的A-A剖视图;
从图5、图6可以看出下鼻道窥镜是一个轴向截面上单边开口的圆锥形筒,它一般用铜材制造,至少是其内表面经光亮镀铬处理,明亮如镜。
手术时,先按常规手术进行处理。当用泪点扩张针扩大泪小点及泪小管,以泪道探针扩通泪总管或鼻泪管,顺泪小管、泪囊、鼻泪管插入麻醉导管直达下鼻道后,将本实用新型的下鼻道窥镜插入下鼻道,借额镜投射过来的光,用窥镜窥视到麻醉导管,再将本实用新型的导管钩取器从下鼻道窥镜中间插入下鼻道,用其前端的斜钩槽钩住导管,用手指推动推销〔3〕,借固结在推销上的钢针〔4〕和钢管〔2〕将导管夹持住,拖引出鼻孔外;将细尼龙丝双叠逆行插入导管内一段,再将硅胶管切成条状结成环形,套在双叠尼龙丝内,引入鼻泪管嵌住。
经发明人许多例临床实践证明,过去手术需要比较好的手术条件(县级以上医院),现在在较简陋的条件下就能做了;过去需要有相当实践经验的医护人员施术,现在一般医护人员就能做了;过去手术需要几个钟头,现在只要几十分钟了;过去病人必须住院,现在不必住院了,因而给病人节约了医疗费用,而且器械本身的制造技术也简单,因此,本实用新型组合器械有着它自己的优点。
