Description

一种骨外科用螺丝钉
技术领域
本实用新型属于医疗器械,具体为一种骨外科用的螺丝钉。
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”字形或者为“--”型,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,且医生在取下这种螺丝钉的过程中不好用力,因此使用起来不够安全方便。
实用新型内容:
本实用新型的目的是克服现有骨外科用螺钉缺陷,提供一种操作更安全方便的骨外科用螺钉。
本实用新型的技术方案是:一种骨外科用螺丝钉,其特征是:在该螺丝钉的尾部顶面边沿内有十字形凹槽。
本实用新型的有益效果是:结构简单,类似于普通的十字花螺钉,再配用相应的十字花螺丝刀,使用起来非常习惯和方便。
附图说明:
附图1为本实用新型的结构简图。
图中,1.螺丝钉,2.十字形凹槽,3.尾部顶面。
具体实施方式:
一种骨外科用螺丝钉,其特征是:在该螺丝钉(1)的尾部顶面(3)边沿内有十字形凹槽(2)。使用时,相应构造的螺丝刀刀头插在螺丝钉(1)的十字形凹槽(2)内,螺丝刀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。
