Abstract

本实用新型涉及医疗器械技术领域，公开了一种便于小瞳孔白内障术中牵拉虹膜、扩大瞳孔、提高小瞳孔白内障手术效率的虹膜分离钩。其包括分离钩手柄和分离钩头部，分离钩后部与分离钩前部成120°连接，分离钩头部位于分离钩前部末端，分离钩头部与分离钩前部末端形成“v”形，分离钩头部长度设为0.5mm。本实用新型具有便于扩大瞳孔，减轻创伤，易于操作的优点。

Description

一种虹膜分离钩
技术领域
本实用新型属于医疗器械技术领域，具体涉及一种眼科手术用虹膜分离钩。
背景技术
眼科白内障手术中，对于因各种原因引起的小瞳孔，手术前散瞳剂不能散大瞳孔，特别是合并闭角型青光眼、糖尿病、葡萄膜炎的患者，需在手术中使用器械牵拉虹膜，将瞳孔散大，以便完成白内障手术。以往的虹膜分离钩为单钩状，牵拉分离手术切口对侧的虹膜时容易滑脱，两个单钩状虹膜分离钩行眼内牵拉虹膜扩大瞳孔，几乎不可能实现，造成手术中反复操作，刺激虹膜组织，加重术后的炎症反应，影响了此类患者的白内障手术的质量。
发明内容
本实用新型的目的在于针对现有虹膜分离钩的不足之处，提供一种能提高手术效率，减轻创伤的虹膜分离钩。
本实用新型的技术方案是：包括分离钩手柄和分离钩头部，分离钩后部与分离钩前部成120°连接，分离钩头部位于分离钩前部末端，特征在于分离钩头部与分离钩前部末端形成“v”形，其角度设为30°，分离钩头部长度设为0.5mm，其截面呈圆形。
有益效果：本实用新型结构简单，使用方便，由于分离钩末端呈“v”形，牵拉分离手术切口对侧的虹膜时，可将分离钩末端卡在虹膜边缘向对侧推拉，同时使用以前的单钩状虹膜分离钩牵拉手术切口侧的虹膜，牵拉后瞳孔散大明显，避免了手术中的创伤，提高了白内障的手术效率。
附图说明
附图1为本实用新型的结构示意图。
具体实施方式
参考附图1，虹膜分离钩包括分离钩手柄1和分离钩头部4，分离钩后部2与分离钩前部3成120°连接，分离钩头部4位于分离钩前部3末端，分离钩头部4与分离钩前部3末端形成“v”形，其角度设为30°，分离钩头部4长度设为0.5mm，其截面呈圆形。扩大瞳孔时，对于手术切口对侧的虹膜组织，分离钩末端的“v”形结构可以卡在虹膜边缘向对侧用力推，同时使用以前的单钩状虹膜分离钩牵拉手术切口侧的虹膜，达到有效的散大瞳孔的作用。
