Abstract

本实用新型提供了一种能使骨折钢板不滑动,不转动,便于固定的可调槽式三爪固定器,本实用新型由固定爪、滑动爪及顶丝构成,在滑动爪上开有钢板槽,钢板槽的一端是一滑板,滑动爪上开有滑孔,滑板通过固定螺栓固定在滑动爪上,且滑板可通过螺栓沿滑孔在滑动爪上滑动。使用时,根据骨折钢板的宽度,调整滑板,用螺栓固定,使钢板槽的宽窄恰到好处即可。本实用新型结构简单,操作调整方便,适应不同宽度的骨折钢板,使骨折固定可靠,手术操作方便,省时、省力,减少病员痛苦。

Description

可调槽式三爪固定器
技术领域
本实用新型涉及一种医院外科用于四肢骨折钢板内固定的三爪固定器。
背景技术
目前,用于四肢骨折钢板内固定的三爪固定器的固定爪和滑动爪都是呈圆弧状,对骨折端的固定是环形,受力不在同一平面上,固定不稳,尤其用摇钻钻孔时,骨折钢板易移位和旋转,操作困难,不仅难以掌握,还给病人增加痛苦。
发明内容
本实用新型的发明目的是提供一种能使骨折钢板不滑动,不转动,便于固定的可调槽式三爪固定器。本实用新型的发明目的是这样实现的:本实用新型由固定爪、滑动爪及顶丝构成,在滑动爪上开有钢板槽,钢板槽的一端是一滑板,滑动爪上开有滑孔,滑板通过固定螺栓固定在滑动爪上,且滑板可通过螺栓沿滑孔在滑动爪上滑动,便于调整钢板槽的宽度。使用时,根据骨折钢板的宽度,调整滑板,用螺栓固定,使钢板槽的宽窄恰到好处即可。
本实用新型结构简单,操作调整方便,适应不同宽度的骨折钢板,骨折钢板嵌在钢板槽内,不滑动,不转动,使骨折固定可靠,手术操作方便,省时、省力,减少病员痛苦。
附图说明
附图是本实用新型可调槽式三爪固定器的示意图。
图中,1、固定爪,2、滑动爪,3、顶丝,4、钢板槽,5、滑板,6、滑孔,7、螺栓。
具体实施方式
由图可知,本实用新型由固定爪1、滑动爪2及顶丝3构成,在滑动爪2上开有钢板槽4,钢板槽4的一端是一滑板5,滑动爪2上开有滑孔6,滑板5通过固定螺栓7固定在滑动爪2上,且滑板5可通过螺栓7沿滑孔6在滑动爪2上滑动。
使用时,根据骨折钢板的宽度,调整滑板,用螺栓固定,使钢板槽的宽窄恰到好处即可。
