Description

骨科用螺丝钉
技术领域:
本实用新型属于骨科用医疗器具技术领域,具体地讲是一种骨科用螺丝钉。
背景技术:
在骨科手术中,经常需要用螺丝刀上紧螺钉,目前骨科使用的螺钉尾部的凹槽为“一”字形,使用这种螺钉时,螺丝刀会在螺钉尾部的凹槽内滑动,影响手术进程,且这种螺丝钉手术医生在取下的过程中不好用力,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钉。
本实用新型的技术方案是:包括螺丝钉,其特征是在螺丝钉尾部设计有两个长方形凹槽。
本实用新型的有益效果是:本实用新型结构简单,使用方便。在旋入和旋出螺丝钉时,相应构造的螺丝刀头插在两个长方形凹槽内,不论向哪个方向滑动,都有其它的凹槽壁给予阻挡,且在转动时利于用力,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、螺丝钉,2、长方形凹槽。
具体实施方式:
包括螺丝钉1,其特征是在螺丝钉1尾部设计有两个长方形凹槽2。使用时,相应构造的螺丝刀刀头插在螺丝钉1的尾部长方形凹槽2内,螺丝刀头在两个长方形凹槽2内不论向哪个方向滑动,都有其它的凹槽壁给予阻挡,使螺丝刀不会滑出,且手术医生用力方便。
