Abstract

本实用新型公开了一种骨科用螺母,具有凹槽,在螺母每一扳手平面旋出方一侧加凹槽,凹槽深、宽均为1-2mm、与平面成15-20度角,在进行手术时,只需暴露内固定物,勿需扩大手术范围,不置扳手,应用一扁头器械顶住螺母凹槽击打,即可将螺母退出,取出内固定物。

Description

骨科用螺母
技术领域
本实用新型涉及医学用品,直接涉及骨科用螺母。
背景技术
目前,行骨科内固定物取出术时,常因手术空间小,部位深,局部解剖结构复杂,螺母扳手放置困难,需扩大手术范围,部分病人植骨后,内固定物周围易形成骨壳,需完全剔除内固定物周围骨壳后方可进行操作,加大了手术创伤,增加了手术难度。
发明内容
本实用新型的目的就是要提供一种骨科用螺母,它能有效地克服现有螺母扳手放置困难的问题。
本实用新型的目的是这样实现的:在螺母每一扳手平面旋出方一侧加凹槽,凹槽深、宽均为1-2mm、与平面成15-20度角,在进行手术时,只需暴露内固定物,勿需扩大手术范围,不置扳手,应用一扁头器械顶住螺母凹槽1击打,即可将螺母退出,从而取出内固定物。
附图说明
附图是本实用新型的结构原理图,下面结合附图对本实用新型作进一步说明。
具体实施方式
附图示出了本实用新型的结构,具有凹槽1,在螺母每一扳手平面旋出方一侧加凹槽1,凹槽1深、宽均为1-2mm、与平面成15-20度角,在进行手术时,只需暴露内固定物,勿需扩大手术范围,不置扳手,应用一扁头器械顶住螺母凹槽1击打,即可将螺母退出,从而取出内固定物。

Claims (2)

1.一种骨科用螺母,其特征是:具有在螺母每一扳手平面旋出方凹槽(1)。
2.根据权利要求1所述的一种骨科用螺母,其特征是:凹槽(1)深、宽均为1-2mm、与平面成15-20度角,手术时,只需用一扁头器械顶住凹槽(1)击打,即可将螺母退出。
