Abstract

本发明涉及一种医疗用具，尤其是辅助型骨钉。该骨钉包括钉帽、钉体和钉槽，钉帽上表面设有钉槽，钉体固定在钉帽下表面，钉帽底部两侧分别设有弹簧体，使用此骨钉能够在取钉时提供辅助撑力，延长了其使用寿命。

Description

辅助型骨钉
技术领域
本发明涉及一种医疗用具，尤其是辅助型骨钉。
背景技术
目前临床所使用的骨钉主要由钉帽和钉体组成，钉帽中间设有钉槽，以便于安装和拆卸骨钉，但现有的骨钉的取出只能依靠人力，费时费力。
发明内容
为了克服现有的骨钉的取出费时费力的不足，本发明提供了辅助型骨钉。
本发明解决其技术问题所采用的技术方案是：辅助型骨钉，包括钉帽、钉体和钉槽，钉帽上表面设有钉槽，钉体固定在钉帽下表面，钉帽底部两侧分别设有弹簧体。
本发明的有益效果是，使用此骨钉能够在取钉时提供辅助撑力，延长了其使用寿命。
附图说明
下面结合附图和实施例对本发明进一步说明。
图1是本发明的结构示意图；
图中1.钉帽，2.钉体，3.钉槽，4.弹簧体。
 
具体实施方式
如图1是本发明的结构示意图，辅助型骨钉，包括钉帽1、钉体2和钉槽3，钉帽1上表面设有钉槽3，钉体2固定在钉帽2下表面，钉帽1底部两侧分别设有弹簧体4。
当骨钉被拧进骨头里时，钉帽2下的弹簧体4会被压紧，而当骨钉被取出时，会借用弹簧体4的恢复形变而提供辅助动力，使用此骨钉能够在取钉时提供辅助撑力，延长了其使用寿命。

Claims (1)
