摘要/Abstract

摘要： 目前系列化接骨板在材料节约和应力分散上不合理。为快捷设计出理想的接骨板，利用平均化骨骼模型，提出通过语义参数编辑优化设计接骨板的方法。首先，为系列化接骨板在数量与尺寸上的分布合理，构建了一种带权值的平均化骨骼模型；然后，基于平均化骨骼模型设计出具有通用性的参数化接骨板，便于后期编辑修改与优化；最后，利用有限元分析，用基于二分策略调整厚度参数来优化接骨板，在满足应力条件下使接骨板材料尽可能少。实验结果显示，对三叶型接骨板和股骨远端Ⅲ型接骨板优化后体积分别减小2.7%和12.2%，最大应力分别减小56.9%和24.4%，表明所提方法能够节省接骨板材料，分散接骨板应力，是一种有效的接骨板优化设计方法。

Abstract: Serial plates are not reasonable in material saving and stress dispersion. To design orthopedic plates quickly and conveniently, a method to optimize plates through editing semantic parameters based on average bone model was proposed. Firstly, for reasonable distribution of serial plates in number and size, an average bone model with weights was created from the exiting bones. Secondly, a common orthopedic plate with semantic parameters was constructed based on average bone model and it could be conveniently modified and optimized. Finally, the thickness of the plate was optimized through finite element analysis and bisection strategy to meet the stress condition and use the least material. The experimental results show that the volume of the optimized femur clover plate and the Ⅲ type of the plate for distal femur is decreased by 2.7% and 12.2%, and the maximum stress is decreased by 56.9% and 24.4% respectively. Experimental results indicate that the proposed method can save material and disperse the stress of plates to effectively construct and optimize the orthopedic plates.

Key words: orthopedic plate, average model, parametric design, thickness optimization, bisection strategy
