Abstract

本发明涉及一种医疗用具，尤其是方型骨钉。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，钉帽上方设有槽块，槽块底部与顶帽为同样大小的方形体，槽块四周设有固定杆，使用此骨钉能够防止因十字槽损坏而影响骨钉的取出，延长了其使用寿命。

Description

方型骨钉
技术领域
本发明涉及一种医疗用具，尤其是方型骨钉。
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，但现有的骨钉如十字槽损坏，就会影响骨钉的取出。
发明内容
为了克服现有的骨钉的十字槽容易损坏的不足，本发明提供了方型骨钉。
本发明解决其技术问题所采用的技术方案是：方型骨钉，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，钉帽上方设有槽块，槽块底部与顶帽为同样大小的方形体，槽块四周设有固定杆。
本发明的有益效果是，使用此骨钉能够防止因十字槽损坏而影响骨钉的取出，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.槽块，5.固定杆。
 
具体实施方式
如图1是本发明的结构示意图，方型骨钉，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上方设有槽块4，槽块4底部与顶帽1为同样大小的方形体，槽块4四周设有固定杆5。
把槽块4放置在钉帽1上，槽块4四周的固定杆5分别于钉帽1四周相贴合，实现定位，然后通过起子拧入槽块4上的十字槽，就可以实现装取，如果槽块4上的十字槽损坏，直接取出更换新槽块4即可，使用此骨钉能够防止因十字槽损坏而影响骨钉的取出，延长了其使用寿命。
