摘要:
目的:建立颈椎C2~7三维有限元模型,探讨不同角度牵引对颈椎间盘的影响。方法:对一名30岁健康成年男性志愿者的颈椎进行CT扫描成像,应用Mimics 10.01、Geomagic Studio逆向工程软件生成颈椎间盘并建立实体CAD模型,然后导入Ansys Workbench 15.0软件得到颈椎C2~7三维有限元模型并进行有效性验证,在所建模型上添加载荷及约束,模拟人体平躺时0~20°变角度牵引,得出牵引治疗中各段颈椎间盘的最优牵引角度。结果:成功建立了C2~7三维有限元模型。同一大小牵引力作用下,颈椎间盘C2~3、C3~4、C4~5、C5~6、C6~7的最优牵引角度分别为2°、4°、8°、13°、17°。结论:建立了有效的颈椎C2~7三维有限元模型。
Abstract:
Aim: To develop a three-dimensional finite element model of human cervical spine C2-7 and explore the effect of cervical discs with cervical traction in different angles.Methods: By using the method of reverse engineering with Mimics 10.01 and Geomagic Studio,a three dimensional geometric CAD model of the cervical spine was developed from the CT scan images of a normal adult male, then, the model was imported into Ansys Workbench 15.0, and a three dimensional finite element model was obtained and verified. After setting the boundary, the model was loaded to simulate the traction under different traction angles from 0-20° when the human body was lying down,so as to obtain optimal traction angles of each cervical discs in traction treatment.Results: The simulations revealed that the optimal traction angles for C2-3,C3-4,C4-5,C5-6,C6-7 were 2°,4°,8°,13°,17°,respectively.Conclusion: The three dimensional finite element model of cervical spine C2-7 has been established.
