Abstract

本实用新型公开了一种治疗腰椎间盘突出的骨科手术器械,特别是腰椎前路减压专用环锯。它由环锯和钻杆组成,环锯是一个空心圆柱体,一端开有锯齿,另一端装有旋转手柄,钻杆为圆柱状,一端开有指示标记,另一端装有凿刀或自攻钻头。手术中,凿刀或自攻钻头插入有病变的椎间盘上,旋转环锯锯开一孔,即可将突出的椎间盘完整摘除。手术简便、无震动、不损伤神经,锯下的骨质可再植入椎体间,以撑开椎体间隙和稳定腰椎。

Description

一种腰椎前路减压专用环锯
本实用新型涉及一种治疗腰椎椎间盘突出的骨科手术器械,特别是腰椎前路减压专用环锯。
现在对腰椎椎间盘突出是采用前路减压的方法进行治疗,即用锤击骨凿在椎体间椎盘上下左右凿一方窗,再用刮匙伸入方窗挖掘底部残余椎间盘组织和破损软骨。该治疗方法的不足是:锤击骨凿震动较大,刮匙挖掘残余椎间盘组织和破损软骨较为费时费力,手术麻烦,且易损伤神经根,造成手术后遗症。
本实用新型的目的是提供一种腰椎前路减压专用环锯,以消除锤击震动、简化手术,不损伤神经根,避免手术后遗症的发生。
为实现上述目的,本实用新型由环锯和钻杆组成,环锯是一个空心圆柱体,其一端开有锯齿,另一端设有旋转手柄,钻杆为圆柱状,装在环锯空心孔内,其位于环锯旋转手柄一端的端顶上开有指示标记,另一端装有凿刀。
上述环锯的直径为20mm,壁厚为0.5mm,长度为200mm,钻杆直径为16mm,总长度为195mm,其中凿刀的长度为15mm,宽度为14mm。
上述的凿刀可换成一自攻钻头,自攻钻头的长度为15mm。
本实用新型由于采用了环锯和钻杆的结构形式,钻杆的自攻钻头或凿刀插入有突出病变的椎间盘上,再旋转环锯锯开一孔,即可将突出的椎间盘完整摘除,不损伤神经根,无锤击震动,也不用挖匙挖掘,手术简便,避免了手术后遗症。此外,锯下来的骨质还可以植入椎体间,以撑开椎体间隙和稳定腰椎。
下面给出本实用新型的实施例及附图,并作进一步说明:
图1(a)、(b)为环锯的正视图和俯视图;
图2(a)(b)、(c)为钻杆的正视图、俯视图和仰视图;
图3为钻杆上装有自攻钻头的剖视图。
按图1(a)、(b)所示,环锯1为空心圆柱体,一端开有锯齿3,另一端装有旋转手柄2。环锯1的直径为20mm,长度为200mm,壁厚为0.5mm。
按图2(a)、(b)、(c)所示,钻杆4为圆柱状,使用中装在环锯的空心孔内,在位于环锯手柄一端的端面上开了指示标记6,另一端装有凿刀5。钻杆4的直径为16mm,总长度为195mm,其中凿刀5的长度为15mm,宽度为14mm。按图3所示,钻杆4的另一端原装有凿刀,可换装为自攻钻头7,自攻钻头7的长度为15mm。
使用中,先将钻杆4的凿刀5或自攻钻头7插入有突出病变的椎间盘上,再将环锯1套在钻杆4外,然后按锯齿3的锯入方向转动旋转手柄2,随着环锯1的逐步锯入,钻杆4也逐渐在环锯1的空心孔中冒出,当见到钻杆4的指示标记6也开始随环锯1转动时,椎体间椎盘上已锯开一孔了,即可将突出的椎间盘完整地摘除。锯下的骨质还可以植入椎体间,以撑开椎体间隙和稳定腰椎。
