Abstract

本实用新型涉及一种可以钻左旋丝孔的骨科医用左旋钻头,它是在一个金属钻杆上镂刻有左旋凹槽。使用时,将钻头放入钻孔的位置,左旋转即可钻出左旋丝纹的钻孔。本实用新型解决了左旋丝锥所需配套的钻孔问题。

Description

骨科医用左旋钻头
技术领域
本实用新型涉及骨科医用材料,尤其涉及钻孔用的钻头。
背景技术
目前,医学骨科临床使用的钻头凹槽为右旋方向旋转,所钻的钻孔不利于左旋丝锥套丝,所以很需要一个与左旋丝锥螺纹配套的钻左旋孔的钻头。
发明内容
本实用新型为了解决左旋丝锥的钻孔问题,提供一种骨科医用左旋钻头。
为解决上述问题,本实用新型的结构是,包括一根金属钻杆,金属钻杆上镂刻有左旋凹槽。
使用时,将钻头放入钻孔的位置,左旋转即可钻出左旋丝纹的钻孔。
本实用新型的优点是:由于钻头的凹槽为左旋方向旋转,所钻的钻孔为左旋孔,有利于左旋丝锥套丝,解决了左旋丝锥所需配套的钻孔问题。
附图说明
图1是左旋钻头的构造图。
图中:1—钻杆,2—左旋转凹槽。
具体实施方式
下面结合附图进一步说明本实用新型的结构。
从图1可以看出,本实用新型是在钻杆1上镂刻有左旋转凹槽2。
