Description

限位固定型金属骨针
技术领域
本发明涉及一种骨针，属于医疗器械类，更具体地说它是一种限位固定型金属骨针。
背景技术
现有骨科手术用的金属骨针的结构特点是：金属骨针上圆柱形杆体的前部连接具有从前向后逐渐加大的圆锥形外周的螺纹部，以便旋入患者的骨头中；杆体的后端部外周开有一个平面式的卡接部，以便使用套筒扳手旋转骨针，进行骨针的旋入或退出。由于涉及到在骨科手术中需要将骨针穿透骨骼固定限位，避免骨针与骨骼之间的相对滑动，因此迫切需要一种具有限位固定功能的固定型金属骨针。
发明内容
本发明的目的在于克服上述现有背景技术的不足之处，而提供一种限位固定型金属骨针。
本发明的目的是通过如下措施来达到的：限位固定型金属骨针，其特征在于，它包括位于前端的刃部和本体，所述的本体上有突起，所述的突起的前端为半圆形，所述的突起的后端为梯形结构，所述的刃部、尾部和本体为一体式结构。
在上述技术方案中，所述的本体上有刻度线。
本发明具有如下优点：刃部对骨头有钻、切、削等作用，本体上的突起方便将骨针固定在骨上，尾部型式可设计为圆形、方形，可配合手动及动力工具操作。
附图说明
图1为本发明的结构示意图。
图中刃部1，本体2，突起3。
具体实施方式
下面结合附图详细说明本发明的实施情况，但它们并不构成对本发明的限定，仅作举例而已。同时通过说明本发明的优点将变得更加清楚和容易理解。
参阅附图可知：本发明限位固定型金属骨针，其特征在于，它包括位于前端的刃部1和本体2，所述的本体2上有突起3，所述的突起3的前端为半圆形，所述的突起3的后端为梯形结构，所述的刃部1、尾部3和本体2为一体式结构。所述的本体2上有刻度线。方便观察骨针进入的深度。本发明尾部型式可设计为圆形、方形，可配合手动及动力工具操作。
其它未详细说明的部分均属于现有技术。
