Abstract

本实用新型涉及一种带槽的泪点扩张器,包括空心圆管,其特征在于:空心圆管的一端为圆锥端,在空心圆管的管壁上开有槽,槽与圆锥端相连通。将本实用新型提供的泪点扩张器插入泪小点后,在不拔出的情况下,冲洗针头能够沿槽进入泪小点,将泪点扩张器抽出后,再行正常程序的泪道冲洗,保证了一次泪点扩张后就能进行泪道冲洗。

Description

一种带槽的泪点扩张器
技术领域
本实用新型涉及一种带槽的泪点扩张器,属于医疗器械技术领域。
背景技术
人双眼近内眦的睑缘上下各有一小点状结构,即泪小点,是泪道(泪液排出系统)的起始部位,当泪小点有闭塞或狭窄时,需行泪点扩张、泪道冲洗。操作时第一步泪点扩张器扩张泪小点后并拔出,第二步冲洗针头插入被扩大的泪小点进行泪道冲洗。由于泪小点是肌性管道的开口,有弹性,所以,常有患者在第一步泪点扩张器拔出后被扩开的泪小点又收缩闭合,使第二步冲洗针头插入困难,导致反复行泪点扩张,增加患者痛苦。
发明内容
本实用新型要解决的技术问题是防止泪点扩张器拔出后泪小点又收缩闭合。
为了解决上述技术问题,本实用新型的技术方案是提供了一种带槽的泪点扩张器,包括空心圆管,其特征在于:空心圆管的一端为圆锥端,在空心圆管的管壁上开有槽,槽与圆锥端相连通。
将本实用新型提供的泪点扩张器插入泪小点后,在不拔出的情况下,冲洗针头能够沿槽进入泪小点,将泪点扩张器抽出后,再行正常程序的泪道冲洗,保证了一次泪点扩张后就能进行泪道冲洗。
附图说明
图1为本实用新型提供的一种带槽的泪点扩张器的结构正视图;
图2为本实用新型提供的一种带槽的泪点扩张器的结构侧视图
具体实施方式
为使本实用新型更明显易懂,兹以优选实施例,并配合附图作详细说明如下。
如图1及图2所示,本实用新型提供的带槽泪点扩张器由空心圆管1组成,空心圆管1的一端被斜切形成圆锥端2,空心圆管1的一侧有一槽3,和圆锥端2相通。操作时,将本泪点扩张器的圆锥端2插入泪小点后不拔出,冲洗针头沿槽3进入泪小点后,再抽出空心圆管1,随后行正常程序的泪道冲洗。
