Description

髓内钉拔出器
技术领域
本实用新型属于一种骨科医疗器械,特别涉及一种用于拔除髓内钉的髓内钉取出器。
背景技术
在骨科临床中,用于骨科固定的髓内钉的末端具有一螺纹孔,在取髓内钉时,一般是将端部具有与上述螺纹孔对应螺纹的拔出杆旋入上述螺纹孔,从而将髓内钉和取出杆连接为一体,然后再拽拔出杆将髓内钉带出。但在实际操作中,上述螺纹孔比较容易损坏往往使得拔出杆无法连接,而且现在各个厂家髓内钉的螺纹孔规格并不完全一致,这就导致拔出杆不能通用,给实际使用带来了诸多困扰。
发明内容
本实用新型的目的就在于针对上述现有技术的缺陷而提供一种通用性好且结构简单实用的髓内钉拔出器。
其技术解决方案如下:髓内钉拔出器,包括直杆和助力杆,两杆铰接为一体,两杆前端相对的内侧面各有一个方形突起,方形突起呈边长为2mm的正方体,与髓内钉尾端的方形缺口大小相适应,直杆的后端联接敲击装置。
本实用新型在使用时,将本实用新型前端的方形突起嵌入螺纹封帽下方的髓内钉尾端方形缺口中,拧紧本实用新型中部的紧固螺栓,将敲击装置向远端击打,即可将髓内钉顺利拔除。本实用新型的使用不受髓内钉螺纹空规格的限制,可适用各种螺纹孔径的髓内钉,具有极好的通用性,具备较高的推广应用价值。
以下结合附图对本实用新型作进一步说明:
附图说明
图为本实用新型的结构示意图。
具体实施方式
如图所示,本实用新型包括直杆1和助力杆2,两杆铰接为一体,两杆前端相对的内侧面各有一个方形突起4,方形突起呈边长为2mm的正方体,与髓内钉5尾端的方形缺口大小相适应,直杆的后端联接敲击装置3。
本实用新型在使用时,将本实用新型前端的方形突起4嵌入螺纹封帽6下方的髓内钉5尾端方形缺口中,拧紧本实用新型中部的紧固螺栓,将敲击装置3向远端击打,即可将髓内钉顺利拔除。
