摘　　要：目的针对临床介入手术中的手术"盲区",以及微创手术中更精准的手术导航需求,本文采用新一代Aurora电磁跟踪技术以辅助手术导航。方法采用Aurora电磁跟踪系统,与含金属材料的手术环境相匹配,利用系统自带的控制软件及其配备的SDK(二次开发包),笔者使用VC编程语言编写了一套适合临床手术导航的实时显示系统,并在荆州市第一人民医院进行了性能测试和对比实验。结果Aurora电磁跟踪系统的手术定位精度从cm级提高为mm级,导航精度的平均值小于2 mm,且可供用户二次开发软件包,编程操作自由方便,与手术器械组合灵活,易于实现手术的智能导航。结论验证了Aurora电磁跟踪系统的优越性能及其在手术导航中的意义,提高了手术导航的准确度和可控性,为临床工作提供了更广阔的应用空间。Objective To aim at ＂blind area＂ in interventional operation and to meet the more precise navigation need in minimally invasive operation, this paper discusses a new Aurora electromagnetic tracking system for surgical navigation. Methods With Aurora electromagnetic tracking system, which contains a serial of metal materials for surgical environment, the control software, and the SDK （secondary development kit）, a real-time display system suitable for surgical navigation is compiled by using VC programming language. Performance tests and comparison experiments are carried out in the First People＇ s Hospital of Jingzhou City. Results The positioning precision of operation improves from centimeter to millimeter and the average of navigation precision is less than 2 mm. The software package can be secondary developed, the programming operation is convenient, and the combination with surgical instrument is flexible, which makes the realization of intelligent surgical navigation. Conclusions Superior performance and the significance of the Aurora electromagnetic tracking system in surgical navigation are verified in this paper. Accuracy and controllability of surgical navigation are improved, which provides a broader clinical application area.
