Abstract

椎间融合器，呈空心多边形体，上下表面均有均布的齿状小突起，中间为椭圆状空心，便于放置人工髓核；在左右两个侧面设置有矩形槽，矩形槽使得融合器具有较好弹性；正侧面有三个通孔，其中两侧的两个孔为光孔，中间的孔为螺纹孔，螺纹孔与椭圆形空心连通，便于手术安装返修手术的时候采用相应带螺纹工具取出和放入椎体；同时中间的孔可以观察人工髓核放置情况；两个侧面的矩形槽设置有上下贯通的孔洞，孔洞结构便于减轻结构重量，同时易于组织长入；均布的齿状小突起便于咬紧上下终板，形成牢固固定；整个胸腰椎融合期采用碳纤维增强聚醚醚酮复合材料，具有良好的生物相容性和耐磨性能。

Description

椎间融合器
技术领域
本发明涉及一种人体颈椎植入器械。
背景技术
传统的颈椎前路减压术在减压完成后需要从患者的髂前取块状骨，然后作椎间植骨融合，而髂前大块取骨后的局部并发症发生率达25％，包括取骨区的疼痛、感染、髂骨翼的骨折等。
颈椎椎间融合器为椎间植骨融合提供了框架，我们只需要在髂前切2cm的小口，用专用的取骨器械取一定量的松质骨，填入椎间融合器中植入椎间就可以取得即刻的稳定。
融合器多采用高分子材料作成，可以透过X线，便于对植骨融合的观察，并且融合器内有金属标志物，可以显示融合器的位置。
要求椎间融合器有一定弹性，最好接近人体组织的弹性模量值，材料具有良好的生物相容性。
发明内容
基于上述内容，本发明提供一种用于颈椎前路手术的椎间融合器。
本发明的目的是通过以下技术方案来实现：
椎间融合器，呈空心多边形体，上下表面均有均布的齿状小突起，中间为椭圆状空心，便于放置人工髓核；在左右两个侧面设置有矩形槽，矩形槽使得融合器具有较好弹性；正侧面有三个通孔，其中两侧的两个孔为光孔，中间的孔为螺纹孔，螺纹孔与椭圆形空心连通，便于手术安装返修手术的时候采用相应带螺纹工具取出和放入椎体；同时中间的孔可以观察人工髓核放置情况；两个侧面的矩形槽设置有上下贯通的孔洞，孔洞结构便于减轻结构重量，同时易于组织长入；均布的齿状小突起便于咬紧上下终板，形成牢固固定；整个胸腰椎融合期采用碳纤维增强聚醚醚酮复合材料，具有良好的生物相容性和耐磨性能。
附图说明
下面根据附图和实施例对本发明作进一步详细说明。
图1是本发明实施例所述的椎间融合器的结构图；
具体实施方式
如图1所示，椎间融合器，呈空心多边形体，上下表面均有均布的齿状小突起1，中间为椭圆状空心2，便于放置人工髓核；在左右两个侧面设置有矩形槽3，矩形槽3使得融合器具有较好弹性；正侧面有三个通孔，其中两侧的两个孔为光孔4，中间的孔为螺纹孔5，螺纹孔5与椭圆形空心2连通，便于手术安装返修手术的时候采用相应带螺纹工具取出和放入椎体；同时中间的孔可以观察人工髓核放置情况；两个侧面的矩形槽3设置有上下贯通的孔洞6，孔洞结构便于减轻结构重量，同时易于组织长入；均布的齿状小突起1便于咬紧上下终板，形成牢固固定；整个胸腰椎融合期采用碳纤维增强聚醚醚酮复合材料，具有良好的生物相容性和耐磨性能。
