【技术实现步骤摘要】
一种新型骨科用断钉取出装置
本技术涉及医疗器械
,尤其是一种新型骨科用断钉取出装置。
技术介绍
骨折是骨科临床中常见的一种病症,发生骨折后,通常是先将骨折部位进行复位,然后使用螺钉和钢板对骨折部位进行固定,当骨折部位愈合后,再将螺钉拧出患者骨骼,将钢板拆除,由于螺钉长时间存在人们骨骼内会与人体骨骼相连接,取钉操作时容易发生尾帽滑丝或尾帽拧断,导致螺钉难以取出,对于断钉,需要对周围骨骼进行钻孔露出断钉尾部,再使用大口镊子或钳子夹持断钉尾部,旋转取出,这样操作需要用力夹紧断钉,而且旋转时易打滑或脱落,操作费时费力,增加了患者的痛苦,加大了医务人员的工作难度。
技术实现思路
本技术的目的是为了克服上述技术缺点提供一种新型骨科用断钉取出装置。本技术解决技术问题采用的技术方案为:一种新型骨科用断钉取出装置,包括螺杆、导向螺母、连杆、钳臂、钳头,所述导向螺母两侧设有支撑杆,支撑杆的端部上侧设有指环,支撑杆的端部下侧设有斜杆,导向螺母内螺接有螺杆,螺杆上端设有摇把,螺杆下端设有轴承座,轴承座两侧设有支杆,支杆端部通过铰轴铰接有连杆,连杆端部通过铰轴铰接有钳臂,钳臂中部通过铰轴与斜杆铰接在一起,钳臂端部设有钳头,钳头内侧设有螺纹夹持槽。本装置使用时,旋转摇把,螺杆从导向螺母中向下移动,可以使连杆向外撑开钳臂上端,钳臂因为中部和斜杆铰接的约束,钳臂前端带动钳头向内夹紧断钉,螺纹夹持槽的内螺纹会卡住断钉的外螺纹,夹持牢固旋转起钉时不易打滑,夹紧断钉停止摇动摇把后,螺杆在导向螺母中螺纹锁定不会上下移动,因此钳头夹持断钉牢固不易脱落,可以用手指伸入指环中将旋转本装置,将断钉反向旋转 ...
