摘要
为简化股骨远端关节内粉碎性骨折复位手术的操作,提高骨折部位复位的准确性,为手术复位提供一种精确匹配的方法。根据患者CT扫描和三维重建等临床影像学资料为股骨远端粉碎性骨折患者的复位手术设计了一种定位模板,利用自主研发的选区激光熔化快速成型设备DiMetal-280进行了316L不锈钢粉末的基础实验工艺研究,获得优化参数,并用该参数加工设计的手术模板,加工速度快,成型后外形良好,尺寸精度高,在临床手术中获得成功应用,为个体化医学辅助器械的高性能、自动化加工开辟了一种新方法,并为该技术今后在临床的应用推广提供了依据。
In order to simplify the distal femoral comminuted fracture surgery and improve the accuracy of the parts to be reset,a kind of surgery orienting model for the surgery operation was designed according to the scanning data of computer tomography and the three-dimensional reconstruction image.With the use of DiMetal-280 selective laser melting rapid prototyping system,the surgery orienting model of 316L stainless steel was made through orthogonal experiment for processing parameter optimization. The technology of direct manufacturing of surgery orienting model by selective laser melting was noted to have obvious superiority with high speed,precise profile and good accuracy in size when compared with the conventional one. The model was applied in a real surgical operation for thighbone replacement; it worked well. The successful development of the model provides a new method for the automatic manufacture of customized surgery model,thus building a foundation for more clinical applications in the future.
