【技术实现步骤摘要】
本专利技术涉及医疗设备
,具体涉及一种骨外科取钉装置。
技术介绍
医学临床中,骨折是骨创伤常见的疾病之一。治疗骨折常采用的方法是实施内固定手术,即将骨折部位复位后,借助于由金属材料制成的接骨板和螺钉将复位后的骨骼连接起来。在实施内固定手术后取下接骨板的过程中,需要将螺钉拆下,因不同的原因常使螺钉折断,很难将螺钉通过螺丝刀等工具旋拧出,取钉过程费时费用,还容易增加创伤和手术时间,甚至放弃取钉,让其终生留在骨骼内,给患者带来诸多不便。
技术实现思路
针对现有技术的不足,本专利技术提供一种骨外科取钉装置,克服了现有技术的不足,设计合理,结构紧凑,通过伸缩套和转动套及支撑臂可以实现取钉螺杆360度旋转,调节到合适操作的位置,然后通过螺杆调节到钉杆位置,通过旋拧夹紧螺栓从而使夹钉钳的夹板抓牢螺钉的端部,再继续旋拧螺杆即可将螺钉旋拧出,操作方便。本专利技术所要解决的技术问题可以通过以下技术方案来是实现:一种骨外科取钉装置,包括托台和支撑臂,托台下端设有支撑腿支撑于地面,所述支撑臂下端转动设置托台上,所述的支撑臂前端设有伸缩套,所述的伸缩套上设有转动套,转动套侧壁通过转动件,转动设置于伸缩套上,所述的转动套中插入有螺杆,转动套前端部内设有内螺纹,螺杆与转动套通过螺纹配合,所述的螺杆下端设有夹钉钳,所述的螺杆前端部还设有夹紧螺栓,所述的夹紧螺栓下端部靠近夹钉钳。所述的夹钉钳由两个夹板构成,前端张开,末端铰链连接于螺杆上。两个所述的夹板之间设有支撑弹簧。所述的夹紧螺栓下端部具有向下延伸夹紧部 ...
