Description

防损型骨钉
技术领域
本发明涉及一种医疗用具，尤其是防损型骨钉。
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，但现有的骨钉的钉帽可能会对周围的组织造成损害。
发明内容
为了克服现有的骨钉的钉帽容易损坏组织的不足，本发明提供了防损型骨钉。
本发明解决其技术问题所采用的技术方案是：防损型骨钉，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，钉帽上套设有防损帽，防损帽为圆弧形套。
本发明的有益效果是，使用此骨钉能够防止钉帽刮伤周围组织，提高了其实用性。
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.防损帽。
 
具体实施方式
如图1是本发明的结构示意图，防损型骨钉，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上套设有防损帽4，防损帽4为圆弧形套。
首先把钉体2拧入骨头中，然后把圆弧形的金属防损帽4套设在钉帽1上，这样由于防损帽4四周都没有菱角，可以很好的保护周围组织，最后当要取出钉体2时，只需要取下防损帽4就可以拧钉帽1了，使用此骨钉能够防止钉帽刮伤周围组织，提高了其实用性。
