摘要:: 针对传统脊柱侧弯矫形器存在设计效率低、贴合性差、加工周期长等问题，本研究基于色努矫形原理，提出采用3D打印技术定制脊柱侧弯矫形器模块化的流程方法。通过构建脊柱侧弯矫形器及调整垫块的三维模型，利用RODIN4D软件分析预测计算矫正过程中的生物力学变化，提出一种矫形器模块化调整的方法。根据个体特征，定制矫正时不同阶段涉及的调整垫块所需的形变量，进行多阶段垫块的3D预制打印，实现矫形调整垫块精准的空间填充与生物力学边缘的高效贴合。基于3D打印技术的个性定制矫形器在治疗周期中模块化调整演进，可以有效提升医师的设计效率，保证患者的穿戴舒适度以及治疗效果。

Abstract:: In view of the low design efficiency, poor fit and long processing cycle of traditional scoliosis orthopedic devices, we proposed a process method based on the toner orthopedic principle with 3D printing technology to customize scoliosis orthopedic appliance modular. The three-dimensional model of scoliosis orthopedic appliance was established, and the biomechanical changes in the correction process were analyzed and predicted by RODIN4D software. According to individual characteristics, shape variables needed for adjusting pads involved in different stages of the correction process were customized, and 3D prefabrication of multi-stage pads was carried out to achieve accurate space filling of orthopedic adjustment pads and efficient fitting of biomechanical edges. Customized orthotics based on 3D printing technology can be modularized and adjusted in the treatment cycle, which can effectively improve the design efficiency of doctors and ensure the comfort of patients and the treatment effect.
