Abstract

本发明涉及一种加压螺纹导针,包括杆部,三角刃以及加压螺纹段;杆部的上部设有加压螺纹段,加压螺纹段的头部设有三角刃;加压螺纹段为变距螺纹段,使其在旋入两骨折块时产生相对运动,从而起到加压的效果。该螺纹加压骨导引针在骨科手术中用于骨折区临时加压固定的作用。本发明的特点:对骨折区起到临时加压固定,可临时替代其它加压固定医疗器械的使用,操作简单,手术效果好。

Description

一种加压螺纹导针
技术领域
本发明涉及骨科医疗器械领域,骨科手术中用于骨折区临时加压固定,尤其涉及到一种加压螺纹导针。
背景技术
克氏针,一种骨科常用的内固定材料,常被用在骨科手术中骨折块的临时固定,可固定骨折于解剖位置,但是无法起到加压作用;而利用其它加压固定医疗器械进行加压固定,操作复杂。
发明内容
鉴于现有技术的上述缺陷,本发明的目的是在骨科手术中,对骨折块进行临时固定时也起到加压的效果。
本发明的目的是通过以下技术方案来实现的:
一种加压螺纹导针,包括杆部,三角刃以及加压螺纹段;杆部的上部设有加压螺纹段,加压螺纹段的头部设有三角刃;加压螺纹段为变距螺纹段,使其在旋入两骨折块时产生相对运动,从而起到加压的效果。
同现有技术相比,本发明的特点和进步如下:
1、本发明的加压螺纹导针,对骨折区起到临时加压固定,可临时替代其它加压固定医疗器械的使用,操作简单,手术效果好。
2、本发明的加压螺纹导针,在导引针的头部增加变距螺纹段,使其在旋入两骨折块时产生相对运动,从而起到加压的效果。
附图说明
图1:加压螺纹导针结构示意图;
图2:图1中加压螺纹导针头部A局部放大示意图。
具体实施方式
下面结合附图和实施例对本发明作进一步的说明。
如图1-2所示,一种加压螺纹导针,包括杆部1,三角刃2以及加压螺纹段3;杆部1的上部设有加压螺纹段3,加压螺纹段3的头部设有三角刃2;加压螺纹段3为变距螺纹段,使其在旋入两骨折块时产生相对运动,从而起到加压的效果。
但是,本技术领域中的普通技术人员应当认识到,以上的实施例仅是用来说明本发明,而并非用作为对本发明的限定,只要在本发明的实质精神范围内,对以上所述实施例的变化、变型都将落在本发明的权利要求书范围内。
