【摘要】：目的介绍一种标准截面形状定制型股骨柄假体结构以及自行开发的设计方法。方法首先利用DICOM格式的患者股骨CT图像,重建患者股骨近端模型;根据重建出的患者股骨近端模型构建股骨柄假体匹配段矩形的截面边界,并在矩形截面边界内用简单的线条初步构建出假体的截面轮廓曲线;利用股骨近端模型对初步设计出的股骨柄假体进行验证,并通过调整设计参数使最终设计出的个性化股骨柄假体与患者股骨髓腔相匹配。结果定制型人工髋关节股骨柄假体采用标准截面形状,便于快速设计出个性化假体,而且设计操作简单。参数化程序设计大大降低了个性化股骨柄假体的设计工作量。结论标准截面形状定制型股骨柄假体的设计将有助于提高定制型人工髋关节置换手术的成功率,促进定制型股骨柄假体在临床上的应用,进一步提高患者的生活质量。
[Abstract]:Objective to introduce a custom-made femoral prosthesis with standard cross-section shape and the design method developed by ourselves. Methods the proximal femur model was reconstructed by using CT images of patients with DICOM format. According to the reconstruction of the proximal femur model, the section boundary of the matched segment of the prosthetic prosthesis of the femur was constructed, and the cross-section contour curve of the prosthesis was preliminarily constructed with simple lines within the rectangular cross-section boundary. The proximal femur model was used to verify the preliminary designed prosthesis of femur petiole. By adjusting the design parameters, the individualized femoral handle prosthesis was designed to match the femoral medullary cavity of the patient. Results the customized hip joint femur pedicle prosthesis adopted the standard section shape, which was convenient for the rapid design of the individualized prosthesis. The parameterized programming greatly reduces the design workload of the personalized femoral handle prosthesis. Conclusion the design of the customized femoral handle prosthesis with standard cross-section shape will be helpful to improve the customized hip prosthesis. The success rate of the operation, To promote the clinical application of customized femoral handle prosthesis and further improve the quality of life of patients.
