【摘要】：目的介紹一種標準截面形狀定制型股骨柄假體結構以及自行開發(fā)的設計方法。方法首先利用DICOM格式的患者股骨CT圖像,重建患者股骨近端模型;根據(jù)重建出的患者股骨近端模型構建股骨柄假體匹配段矩形的截面邊界,并在矩形截面邊界內用簡單的線條初步構建出假體的截面輪廓曲線;利用股骨近端模型對初步設計出的股骨柄假體進行驗證,并通過調整設計參數(shù)使最終設計出的個性化股骨柄假體與患者股骨髓腔相匹配。結果定制型人工髖關節(jié)股骨柄假體采用標準截面形狀,便于快速設計出個性化假體,而且設計操作簡單。參數(shù)化程序設計大大降低了個性化股骨柄假體的設計工作量。結論標準截面形狀定制型股骨柄假體的設計將有助于提高定制型人工髖關節(jié)置換手術的成功率,促進定制型股骨柄假體在臨床上的應用,進一步提高患者的生活質量。
[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.
