摘要
目的研究兔股骨三维生物力学模型的建立方法。方法新西兰大白兔1只,雌性,兔龄1年。制作兔股骨标本,获取股骨断层图像,输入计算机后经处理得到边界轮廓线,再通过自编程序,获取建模时所用的轮廓线坐标,将坐标数据输入建模软件,建立三维实体模型。结果建立了兔股骨的完整三维模型,真实模拟了股骨的解剖形态。结论兔股骨三维生物力学模型的建立为下一步通过有限元法确定振动的最佳参数,提高骨密度奠定基础。
Objective To discuss the method of constructing biomechanical model of rabbit femur. Methods The sample of rabbit femur was prepared as follows：firstly ,femur section images were obtained ,then the image was put into the computer and processed to get the boundary contour line ; secondly, through programming the contour line coordinate for modeling was obtained, then the data were put into the model software to find the three-dimensional entity model. Results Whole three dimensional model of rabbit femur was constructed. It simulated actually dissection form of femur. Conclusion The establishment of the model lays a foundation for ascertaining optimal parameter of vibration improving bone minery density by finite element analysis.
