Abstract

本实用新型涉及一种新型泪道扩张支架,属于医疗器械领域,由硅胶管1、网状钛金属层2和尼龙线3构成。其特征是:硅胶管1为一锥状长软管,硅胶管1的内部衬有网状钛金属层2,硅胶管1的外表面设有多个小孔4,用于药物和气体向外渗透,尼龙线3与硅胶管1的锥尖相连接,用于导引支架,并使之逐步深入。本实用新型结构简单,使用方便,在扩张泪道过程中,可同时将药物和气体渗入泪道,减轻了患者的痛苦,疗效安全可靠,且术后面部不留瘢痕,复发率低,是一种理想的泪道扩张支架。

Description

新型泪道扩张支架
技术领域:本实用新型属于医疗器械领域,特别涉及一种在扩张泪道过程中,可同时将药物和气体渗入泪道,术后面部不留瘢痕的新型泪道扩张支架。
背景技术:泪道阻塞导致的溢泪症是一种眼科常见病,病因多见于先天性泪道阻塞、鼻泪管狭窄或梗阻、慢性泪囊炎等。目前,对于泪道阻塞的治疗方法,大多采用泪道冲洗、激光疏通、泪道置管、泪囊鼻腔吻合术等,这些治疗方法,虽然具有一定的疗效,但是都伴有各种不足之处,例如术后遗留面部瘢痕、易复发、手术操作困难、义管脱落、仪器设备价格昂贵等,给患者带来不必要的损失和痛苦。
发明内容:本实用新型的目的在于克服现有技术条件的不足,提供一种在扩张泪道过程中,可同时将药物和气体渗入泪道,术后面部不留瘢痕的新型泪道扩张支架。
为实现上述目的,本实用新型采取了如下技术方案:该新型泪道扩张支架,由硅胶管、网状钛金属层和尼龙线构成,硅胶管为一锥状长软管,硅胶管的内部衬有网状钛金属层,硅胶管的外表面设有多个小孔,用于药物和气体向外渗透,尼龙线与硅胶管的锥尖相连接,用于导引支架,并使之逐步深入。
本实用新型,结构简单,使用方便,在扩张泪道过程中,可同时将药物和气体渗入泪道,减轻了患者的痛苦,疗效安全可靠,且术后面部不留瘢痕,复发率低,是一种理想的泪道扩张支架。
附图说明:以下结合附图对本实用新型作进一步说明。
图1为本实用新型的结构示意图。
参照附图1,1、硅胶管,2、网状钛金属层,3、尼龙线,4、小孔。
具体实施方式:本实用新型,由硅胶管1、网状钛金属层2和尼龙线3构成,硅胶管1为一锥状长软管,硅胶管1的内部衬有网状钛金属层2,硅胶管1的外表面设有多个小孔4,尼龙线3与硅胶管1的锥尖相连接。
使用本实用新型时,先将尼龙线3穿过泪道,然后用尼龙线牵引硅胶管1,使之逐步深入,如果在扩张泪道的同时需要向泪道中注入气体或药物,被注入的气体或药物则沿小孔4渗透至泪道周壁。
