摘要
建立了股骨头和股骨颈的数学模型,并在此基础上开发了髋关节表面置换手术导航系统模型建立功能模块。首先,基于数值优化理论,推导了股骨头和股骨颈的数学表示;然后,采用光学跟踪、数值分析和计算机图形学等相关技术,重建了股骨头和股骨颈的数字模型;实验结果表明所开发的髋关节表面置换手术导航系统模型建立功能模块能够帮助提高髋关节表面置换手术的准确性。
The construction of mathematical model of femoral head and neck and a computer-assisted femoral head resurfacing system were introduced. On the basis of numerical optimization theory, a series of mathematical equations were derived to describe the femoral head and neck. By adopting techniques and tools such as optical tracking, numerical analysis, and computer graphics, a 3-1） digital model of femoral head and neck was reconstructed, and a computer-assisted femoral head resurfacing （FHR） system was developed. Experimental results show that the system provides a useful tool for performing the femoral head resurfacing surgery quickly and accurately.
