摘要
提出一种精确匹配的定制型医用内植物设计与制造方法。采用医学图像处理和数字几何处理技术从CT图像序列中获得以三角面描述的骨组织面模型。对几何模型进行三角面精简、碎片清除、切割、镜像和合并等几何运算后,用LOM法制作实际大小的快速原型模型。快速原型有利于精确匹配的内植物制作,对手术实施也有导向作用。利用该技术已进行30多例颌骨修复手术,效果良好。
A new method to fabricate exact-fit medical implants is proposed. Medical image processing and digital geometry processing are adopted for bone triangular mesh modeling from CT image series. After geometric operations such as decimation, defragmentation, cutting and mirroring are applied to the original triangular mesh, an RP model of same size as the bone is fabricated with LOM method. RP models are used for manufacturing exact-fit implants and they also serve surgery-guiding purpose. This novel technique has been applied in over 30 clinical cases, and it is proven to be practicable.
