Abstract

本实用新型公开了一种骨科用螺丝刀,属于骨科用医疗器械技术领域。包括手柄和带有“一”字形刀刃的刀杆构成,其特征是刀杆的下端刀刃的两侧各设有一挡杆,挡杆的下端略长于刀刃的两侧。本实用新型结构简单,使用方便。在旋入和旋出螺钉时,由于有挡杆的阻挡,刀刃不会在螺钉的尾槽内滑动,更不会滑出,使医生操作安全方便。

Description

一种骨科用螺丝刀
技术领域:
本实用新型属于骨科用医疗器械技术领域,具体地讲是一种骨科用螺丝刀。
背景技术:
在骨科手术中,经常需要用螺丝刀上紧螺钉,目前骨科“一”字形螺丝刀与普通螺丝刀结构基本相同,即由手柄和带有“一”字形刀刃的刀杆构成,使用这种螺丝刀上紧螺钉时,刀刃会在螺钉的凹槽内滑动,影响手术进程,有时甚至会滑出凹槽,戳伤操作者手指,因此使用不够安全方便。
发明内容:
本实用新型的目的是提供一种操作安全方便的骨科用螺丝刀。
本实用新型的技术方案是:包括手柄和带有“一”字形刀刃的刀杆构成,其特征是刀杆的下端刀刃的两侧各设有一挡杆,挡杆的下端略长于刀刃的两侧。
本实用新型的有益效果是:本实用新型结构简单,使用方便。在旋入和旋出螺钉时,由于有挡杆的阻挡,刀刃不会在螺钉的尾槽内滑动,更不会滑出,使医生操作安全方便。
附图说明:
附图1为本实用新型的结构示意图。
图中1、手柄,2、刀刃,3、刀杆,4、挡杆。
具体实施方式:
包括手柄1和带有“一”字形刀刃2的刀杆构成,其特征是刀杆3的下端刀刃2的两侧各设有一挡杆4,挡杆4的下端略长于刀刃2的两侧。使用时,刀刃2插在螺钉的尾槽内,挡杆4挡在刀刃2及尾槽的两侧,使螺丝刀不会滑出。
