Description

一种新型的最终锁紧扳手
技术领域
本发明属于领域，具体涉及一种新型的最终锁紧扳手。
背景技术
针对脊柱矫形手术中，采用一棒三钉或一棒四钉，在折断可折断压钉时需逐一折断，这样增加了手术的复杂性和时长，同时加大了手术的风险性。所以需要设计制作一种满足一次可折断多个可折断压钉并且满足产品质量要求、有较高的灵活性、制作周期短、且经济适用的专用锁紧扳手，以满足当前手术的需要。
发明内容
本发明为解决现有技术存在的问题而提出，其目的是提供一种新型的最终锁紧扳手。
本发明的技术方案是：
一种新型的最终锁紧扳手，包括扳手组件和握柄，而扳手组件与握柄焊接联接，扳手组件头部为与椎弓根螺钉可折断压钉配合的六方孔，所述扳手组件上设置弹簧片。
所述握柄为T型。
所述的弹簧片为2个。
所述六方孔规格为SW6.5。
本发明结构及制作工艺简单，加工周期短，有较高灵活性，成本低，使用方便，缩短手术时间。
附图说明
图1是本发明的主视图；
图2是本发明的扳手组件剖面图；
图3是本发明的剖视图；
其中：
1 扳手组件 2 握柄
3 六方孔 4 弹簧片。
具体实施方式
以下，参照附图和实施例对本发明进行详细说明：
如图1~3所示，一种新型的最终锁紧扳手，包括扳手组件1和握柄2，而扳手组件1与握柄2焊接联接，扳手组件1头部为与椎弓根螺钉可折断压钉配合的六方孔3，所述扳手组件1上设置弹簧片4。
所述握柄2为T型。
所述的弹簧片4为2个。
所述六方孔3规格为SW6.5。
本具体实施例的使用方法为扳手组件1与握柄2焊接联接，扳手组件1头部为六方孔3与椎弓根螺钉可折断压钉配合，将扳手组件1SW6.4六方孔3插入可折断压钉外六方上，旋转握柄2锁紧压钉并折断可折断部分。扳手组件1上的弹簧片4可挡住可折断压钉的折断部分，通过最终锁紧扳手可实现一次折断所上的所有可折断压钉，方便手术，缩短手术时间。
本发明结构及制作工艺简单，加工周期短，有较高灵活性，成本低，使用方便，缩短手术时间。
