基于腰椎3D模型的矫形器背板设计

Design of Lumbar Orthosis Backbone Based on 3D Model

目的:利用3D打印技术设计个体化的腰椎矫形器背板。方法:从患者CT图像中提取腰椎数据,重建三维模型,导出生成STL文件。用3-matic软件编辑STL文件中的腰椎模型,设计生成背板的三维部件。结果:腰椎矫形器背板部件与腰椎解剖部位紧密贴合。结论:3D打印技术为矫形器设计提供了新的思路和手段。

Objective： To design an individualized lumbar orthosis backbone by 3D printing technologies. Methods： Three-dimensional model was reconstructed using lumbar vertebra data extracted from CT images of some patient. Then STL file of lumbar vertebra model was exported to 3-matic software. The three-dimensional part of orthosis backbone was created by edit and design functions in the software. Results： The part of lumbar orthosis backbone fit in well with anatomical structure of lumbar vertebra. Conclusion： 3D printing technologies provide new ideas and methods for orthosis design.
