Abstract

本实用新型是一种钛合金中空调节式人工椎体，主要由椎体、一对分别带有刺脚的椎体盖组成，椎体轴向设有通孔，内壁带有内螺纹，椎体盖设有带外螺纹的台阶，椎体两端分别和一对椎体盖通过内外螺纹啮合联成一体。本实用新型具有显著的效果，为颈椎、胸椎、腰椎骨节缺损伤病员提供了一种有效的康复技术。

Description

钛合金中空调节式人工椎体
本实用新型涉及的是一种人工椎体，尤其是一种钛合金中空调节式人工椎体，属于医学领域。
目前临床上对于颈椎、胸椎或腰椎患者因病变(以肿瘤为主)或外伤引起的骨节(或椎节的大部分)缺损时，包括因病变手术切除的椎节，传统的手术是取自体髂骨植入，或同时辅以钢板，但此种疗法不仅增加病人痛苦，而且椎节的高度容易丢失。根据对现有技术的检索查新，至今尚未发现有利用钛合金中空调节式人工椎体的这种产品的。
本实用新型是通过以下的技术方案来实现的，本实用新型主要由椎体、一对分别带有刺脚的椎体盖组成，椎体的轴向设有通孔，内壁带有内螺纹，椎体盖设有带外螺纹的台阶，椎体两端分别和一对椎体盖通过螺纹啮合联成一体。椎体盖的轴向距离是可调的，根据实际需要转动椎体，确定轴向尺寸，并分别由设在椎体两端固定螺钉对椎体盖固定。椎体开设若干个腰形槽，椎体盖上也开设有通孔，本实用新型独特的中空设计，将使其腔内放入碎骨块或片而有利于手术后期植入物与椎节间的融合和稳定。椎体盖上带有均布的三个刺脚。椎体上设有若干个调节椎体盖轴向距离的调节孔，椎体内两端的螺纹为同向螺纹，同理一对椎体盖上的螺纹也是同向螺纹。
本实用新型具有显著的效果，为颈椎、胸椎、腰椎骨节缺损伤病员提供了一种有效的康复技术，本实用新型不仅容易植入、撑开和压缩，并可同时恢复病变椎节的正常高度，有利于椎节后期的融合与稳定。而且利用钛合金作为本实用新型的材料，对人体组织生物相容性较好，也不影响磁共振的检查。
以下结合附图进一步描述：
图1本实用新型示意图
图2椎体结构示意图
图3椎体盖端面结构示意图
如图1图2和图3所示，本实用新型主要由椎体1、一对分别带有刺脚3的椎体盖2组成，椎体1轴向设有通孔，内壁带有内螺纹，椎体盖2设有带外螺纹的台阶，椎体两端分别和一对椎体盖2通过内外螺纹啮合联成一体。椎体1两端分别设有固定螺钉4。一对椎体盖2的轴向距离是可调的，椎体1上设有若干个调节孔5，椎体1两端内螺纹和一对椎体盖2上的外螺纹分别是同向螺纹。椎体盖2上设有均布的三个刺脚3。椎体1上还设有若干个腰形槽6，一对椎体盖2上分别设有通孔7。
