Software Development Of Upper Computer For Orthopaedic 3D Printing

In recent years,with the combination of computer and medical fields,the auxiliary role of computers in surgery has become more and more obvious.The good fit between 3D printing technology and orthopedic medicine plays an increasingly important role in the diagnosis of diseases and the formulation of surgical plans.In the practice of orthopedic 3D printing,it was found that the software used had work efficiency and precision problems.The paper designed and implemented the PC software for orthopedic 3D printing work.First,the software integrates model visualization and slicing work into the same system.Aiming at the problem of uneven CT image segmentation,the paper adopts the Fast Marching method with adaptive arrival time and F-Measure value increased by 3.6%;For the problem of loss of original geometric features in denoising,data-driven cascade radial basis network method is used and the paper get a denoising result with an average normal vector error 3.94° at the same time retains the original geometric features of skeleton model;The problem of low slicing efficiency is improved by using the recursive method of intersection between adjacent triangles and adjacent tangent planes,the efficiency of test model slicing is respectively increased by 46.0%,25.0% and 12.3%;For the problem of model deformation in 3D printing,Hilbert curve scanning filling method is adopted in this paper which can get a better 3D printing result.The test results show that the paper development system has improved the bone model reconstruction and model slicing,and improved the work efficiency.After the actual trial of the cooperative hospital,the printed model can better assist the preoperative planning of orthopedics.
