Abstract

本实用新型是一种眼球角膜巩膜穿刺刀，由刀尖、刀刃、刀刃卡、刀尾和刀柄组成，其特征在于刀刃上有刀刃卡；手术操作时，在眼球角膜巩膜瓣下用眼球角膜巩膜穿刺刀在角膜巩膜缘位置刺入前房，因有刀刃卡卡在穿刺口外，因此可控制穿刺的深度和穿刺口的宽度。本眼球角膜巩膜穿刺刀涉及的制造工艺简单，手术操作容易，可用于制作眼球角膜巩膜缘穿刺口，有利于青光眼房水引流装置的引流管的植入。

Description

眼球角膜巩膜穿刺刀
技术领域
本实用新型涉及医疗器械领域，是一种眼球角膜巩膜(简称角巩膜)穿刺刀。
背景技术
现有角巩膜穿刺刀存在有穿刺深度和宽度不易控制，易损伤眼球虹膜和晶体等缺点。
发明内容
本实用新型是提供一种由刀尖、刀刃刺穿眼球角巩膜进入前房，刀刃卡卡在穿刺口外以控制穿刺深度和宽度的眼球角巩膜穿刺刀；手术操作时，在眼球角巩膜瓣下角巩缘位置刺入前房，有利于青光眼房水引流装置的引流管的植入，手术操作容易。
本实用新型是这样实现的：
眼球角巩膜穿刺刀由刀尖、刀刃、刀刃卡、刀尾组成，其中刀尖、刀刃、刀刃卡和刀尾一体制成，刀尾固定在刀柄的一端。
一体制成的刀尖和刀刃易于穿过眼球角巩膜，因刀刃上有刀刃卡，可控制穿刺的深度和穿刺口的宽度，有利于青光眼房水引流装置的引流管的植入。
附图说明
下面结合附图对本实用新型做进一步的说明：
附图1为本实用新型的正面图
附图2为本实用新型的俯视图
附图3为本实用新型的左视图
具体实施方式
将刀尖、刀刃、刀刃卡和刀尾一体制成，刀尾和刀柄的一端固定连接。
手术时在眼球角巩膜瓣下角巩缘位置用角巩膜穿刺刀的刀尖1和刀刃2准确、快速地刺入前房，刀刃卡3将卡在穿刺口外，以控制穿刺的深度和穿刺口的宽度，使穿刺口的宽度有利于青光眼房水引流装置的引流管的植入，刀尾4的作用是与刀柄5固定连接。
