具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
请参阅图1-3，本发明提供一种零切迹颈椎前路椎间融合装置技术方案：包括壳体组件1和固定组件2，壳体组件1包括椎间融合器11和钛金合板12，钛金合板12与椎间融合器11固定连接，且位于椎间融合器11的一侧，固定组件2包括第一螺纹通孔21、第二螺纹通孔22、第三螺纹通孔23、第四螺纹通孔24和自攻螺钉25，第一螺纹通孔21开设于钛金合板12上，第二螺纹通孔22开设于钛金合板12上，且位于第一螺纹通孔21的一侧，第三螺纹通孔23开设于钛金合板12上，且位于第二螺纹通孔22远离第一螺纹通孔21的另一侧，第四螺纹通孔24开设于钛金合板12上，且位于第三螺纹通孔23远离第二螺纹通孔22的一侧，自攻螺钉25的数量为四个，分别贯穿第一螺纹通孔21、第二螺纹通孔22、第三螺纹通孔23和第四螺纹通孔24。
在本实施方式中，通过设置有上下表面呈锯齿状，且切入段为锲形的用PEEK材料制作的椎间融合器，使得在切入时的切口很小，还在钛合金板上设置有倾斜方向相反的第一螺纹通孔、第二螺纹通孔、第三螺纹通孔和第四螺纹通孔，在固定时更加稳定，还设置有用于固定的自攻螺钉，椎间融合器、钛金合板和自攻螺钉，三者配合使用，具有良好的生物相容性、无毒性、无致癌性，并且耐磨、耐腐蚀，还有抗变形能力和抗疲劳强度、固定可靠且使用寿命长。
进一步的，椎间融合器11远离钛金合板12的一端为锲形。
在本实施方式中，椎间融合器11远离钛合金合板12的一端为锲形，在手术时更方便切入，且切口小易于患者恢复。
进一步的，椎间融合器11的上下表面均呈锯齿状。
在本实施方式中，椎间融合器11的上下表面均呈锯齿状，在手术时切入时更加容易省力，并且使得椎间融合器11与骨接触更加紧密。
进一步的，椎间融合器11为PEEK材料。
在本实施方式中，PEEK聚醚醚酮是一种具有耐高温、自润滑、易加工和高机械强度等优异性能的特种工程塑料，用其制作的椎间融合器11生物相容性好。
进一步的，钛金合板12的两端设置有挡板，挡板与钛金合板12呈一体化。
在本实施方式中，挡板防止在椎间融合器11植入的过程中过深打入椎体，保证了切迹的同时也使椎间融合器11可以与椎体良好的贴合。
进一步的，第一螺纹通孔21与第四螺纹通孔24的倾斜方向相同，第二螺纹通孔22与第三螺纹通孔23的倾斜方向相同，第一螺纹通孔21和第四螺纹通孔24的倾斜方向与第二螺纹通孔22和第三螺纹通孔23的倾斜方向相反。
在本实施方式中，第一螺纹通孔21与第四螺纹通孔24以及第二螺纹通孔22和第三螺纹通孔23在固定时分别是倾斜向上或向下，固定时，位于中间的第二螺纹通孔22与第三螺纹通孔23插入的两个自攻螺钉与上部骨或下部骨固定，位于两侧的第一螺纹通孔21和第四螺纹通孔24插入的两个自攻螺钉相应地与下部骨或上部骨固定，安装固定简易，且稳定性好。
本发明的工作原理及使用流程：本发明安装好过后，手术时，将椎间融合器11植入锥间，利用自攻螺钉25分别贯穿位于钛金合板12上的第一螺纹通孔21、第二螺纹通孔22、第三螺纹通孔23、第四螺纹通孔24，固定时，位于中间的第二螺纹通孔22与第三螺纹通孔23插入的两个自攻螺钉与上部骨或下部骨固定，位于两侧的第一螺纹通孔21和第四螺纹通孔24插入的两个自攻螺钉相应地与下部骨或上部骨固定，使得固定更加稳定，钛合金板12上的挡板可以防止在椎间融合器11植入的过程中过深打入椎体，完成了一种零切迹颈椎前路椎间融合装置的使用流程。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
