Abstract

本发明提供一种带定位器的医用髓内钉导针管，所述导针管在管体一侧通过柄把连接有一个定位杆，管体的下端是一个尖锥头。使用时，通过定位杆紧贴人体，可让导针管能避免晃动偏位，所设尖锥头可让导针管能轻松快捷准确的刺入髓内的手术位置，有利加快手术时间，减轻病人手术的痛苦。

Description

带定位器的医用髓内钉导针管
技术领域
本发明涉及一种医用髓内钉导针管，具体的说是一种带定位器的医用髓内钉导针管。
背景技术
医院在为病人做骨髓手术采用髓内钉接骨时，要使用导针管对准手术位置刺入髓内后再顺导针管管体内插入导钉进行接骨，由于髓内钉的导针管体短、细而光滑，很难用手掌控管体，加之管体的刺入端头圆滑，刺入非常不便，导致使用时手术时间长，既增加了病人手术时的痛苦，又会让医生感到劳累。
发明内容
本发明提供一种带定位器的医用髓内钉导针管，具有定位稳定准确，穿刺快捷方便，可减轻病人痛苦的特点。
本发明为技术方案中包括导针管的管体，所提出的具体技术方案如下：将导针管的管体一侧通过柄把连接一个定位杆，并将管体的下端设置为尖锥头。
本发明通过上述技术方案，由于将导针管设置柄把连接定位杆，使用时，手握柄把将定位杆紧贴病人肢体，加之在导针管的端头设置有尖锥头，可稳定、快捷的刺入到准确的位置，有效解决了现有产品存在的不易用手掌握，容易偏移位置和难以快速刺入的问题，可大大降低手术时间，减轻病人手术的痛苦。
附图说明
下面结合附图和实施例对本发明作进一步详述。
附图为本发明结构示意图。
具体实施方式
附图实施例所示：导针管在管体1一侧通过柄把3连接有一个定位杆2，管体1的下端是一个尖锥头4。
