Abstract

一种用于医学骨科膝内翻矫形手术的摆动式弧形锯,包括一个锯体,锯体上方有一限位座和圆盘座,圆盘中间有一花键孔,与石膏锯轴头连接。圆盘座由铆钉固定在锯体上,锯体下方有弧形锯齿,锯矫形骨面用。

Description

本发明属于医学手术器械。
在临床做膝内翻矫形手术中,现在一般都是手术医生用凿子弧形,楔形或人字形切骨。凿子切骨其角度不易掌握。对合不严紧,且有前后不一致(前宽后窄),后方骨皮质易破裂,而且手术时间较长,影响矫形对合的质量和手术的速度。
本发明的目的是避免上述情况的发生,改进了膝内翻矫形手术的缺陷,避免角度不适或反张,提高手术后质量,缩短手术时间,保证手术效果而设计了用于膝内翻矫形手术的弧形摆动式截骨锯。
本发明的基本设计是,弧形锯有一弧形锯体,锯身宽为40-60锯同心圆半径为18-20mm,锯厚为0.5-0.8mm,齿间距为1.2-1.6mm。近端为一圆盘,固定于摆动式(往复式)电机轴头上。
按上述设计制造出来的摆动式弧形锯,在使用时将圆盘锯固定在机头上,远端锯齿与矫形骨呈直角接触,用手指按动电机开关,致锯齿呈往复式摆动,锯断矫形骨,使骨断面呈半圆形杵臼状骨折,其上下,两边缘几乎象两个半径相等的同心圆的两条弧线,可任意调整矫形角度,这样矫形后两断面平整,连接稳定。
下面是本发明的一个最佳实施。如图所示、一个锯体(4)。锯体上方有一限位座(1)和一圆盘座(2)、圆盘中间有一花键孔(3)与电动机轴头花键连接,圆盘由铆钉(6)固定在锯体上,在锯体下方有一弧形锯齿(5)锯矫形骨面用。

Claims (4)
