摘要
复杂曲面重构是工程设计中的难点,而对治疗骨头缺损的个体化钛网塑形来说这一问题尤为突出,针对这一问题提出了一种以三维CT图像为基础,以逆向工程与快速成型技术为支持的钛网成形方法。在本方法中对三维CT数据进行三维重建,利用逆向工程技术对缺损骨骼进行修复重建,并设计出个体化钛网塑形的模具,然后利用快速成型技术进行修复体和钛网塑形模具的加工,最后进行个体化钛网的塑形。结果表明该方法避免了对人体骨头复杂曲面的重构,可以快速进行个体化钛网的塑形的设计与制造。
The reconstruction of complicated surface is the difficulty point for engineering design and it is special true for individual titanium mesh moulding of bone defect therapy. A iming at this problem, a new method based on threedimension CT data and the techniques of reverse engineering and rapid prototyping were proposed. The method carried 3 D rebuilding on 3D CT data, repaired and rebuilded the defect bone with reverse engineering technique and designed the mould of individual titanium mesh, then repaired and process the titanium mesh plastic mould with rapid prototyping technique, then came to the last stage--moulding the individual titanium mesh. The results show that the method avoids the reconstruction of complicated surface of human bone, can design and manufacture the individual titanium mesh moulding repaired.
