脊柱手术个性化椎弓根螺钉的计算机辅助设计
Computer-aided design of personalized pedicle screw in spinal surgery
摘要
Abstract
Personalized design for pedicle screw is an important part of the operation's success in computer-aided spine orthopedic surgery.This design consists of two parts,the first part is making positioning planning for the screw,and the other part is to measure the parameters of the screw.As the traditional method has inaccurate positioning and the opera-tion is not intuitive,a pedicle screw personalized computer-aided design method based on surface rendering algorithm and contour extraction is proposed. Firstly, the paper makes the positioning planning of the pedicle screw based on contour line extracted from spinal section.Secondly,it measures the parameters of the pedicle screw.Finally,it displays the experiment result of virtual surgery and completes the whole process of computer-aided design for personalized pedicle screws.The results of experiment show that this method can obtain the personalized pedicle screws which meet the requirement of the operation.关键词
