摘要
目前医生主要通过患者的X光片来观察、讨论脊柱侧弯病人的情况,但由于人体脊柱解剖结构的复杂性,医生难以直观地从X光片确定患者的手术方案、进行手术模拟或者对脊柱侧弯支具的设计进行指导。我们从医工结合的角度,讨论了由患者CT数据生成人体骨骼快速原型模型STL文件的技术路线,建立了脊柱侧弯的实体模型,通过与快速成型制造系统之间的数据交换,利用叠层实体制造(LOM)技术制作了一例具有完整解剖结构的人体脊柱侧弯模型,对医生们讨论手术方案和进行手术模拟具有重要的临床价值,对医工结合领域的发展具有重要的意义。
At present, doctors discuss the situation of scoliosis patients mainly through their x-ray photograph. Because of the complexity of human spine structure, it is very difficult for doctors to plan ＆ simulate operation or instruct design of scollosis bracket only through the x-ray photograph of patient. In this paper, the technology of forming an STL file from CT data was introduced. The solid model of a scoliosis patient was reconstructed and transferred to RPM system. A human scoliosis model with all spine anatomical structure was manufactured using laminated object manufacturing （LOM）. It has important clinical value for doctors to plan ＆ simulate operation, and it is significant for the development of integration of medicine and engineering.
