Aurora电磁跟踪系统在临床手术导航中的应用

Research on the aurora electromagnetic tracking system in the medical surgical navigation application

目的:针对临床上介入手术中的手术"盲区"以及微创手术中更精准的手术导航需求,采用新一代Aurora电磁跟踪技术辅助手术导航,通过与各种手术器械自由组合解决手术中遇到的各种难题。方法:采用Aurora电磁跟踪系统与含有金属材料的医疗手术环境相匹配,利用电磁跟踪系统自带的控制软件,采用其配备的软件开发工具包(SDK),使用VC编程语言编写一套适合临床手术导航的实时显示系统。结果:通过临床应用,验证了该系统的优点,并体现出Aurora电磁跟踪系统的性能优越。结论:Aurora电磁跟踪系统手术的定位精确,且可供用户使用SDK,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,全面提升了手术导航的准确度和可控度,在医学手术导航中具有深远的意义。

Objective： For clinical interventional procedures in surgery, ＂blind spot＂, as well as minimally invasive surgery more precise surgical navigation requirements, this paper explores the use of a new generation of Aurora electromagnetic tracking technology assisted surgical navigation through free combination with a variety of surgical instruments, surgical further addressed various problems encountered. Method-s： Aurora electromagnetic tracking system used with metal-containing material that matches the medical surgical environment, the use of electromagnetic tracking system comes with control software, the use of which is equipped with the SDK （secondary development package）, I use a set of VC programming language suitable for clinical surgical navigation, real-time display system, and in our hospital different medical surgical navigation application performance test and comparative experiments measured the accuracy of the tracking system, the statistics of various surgical instruments corresponding to different surgical applications. Results： By author in ]ingzhou City, First People＇s Hospital conducted a series of clinical application, verify the advantages of the system, allows doctorsduring surgery even more powerful, fully reflects the Aurora electromagnetic tracking system, superior performance, as well as in the medical surgical navigation important far-reaching significance. Conclusion： By using a variety of surgical instruments and medical surgical navigation in different experiments, we found that Aurora electromagnetic tracking system surgery centimeter-level positioning accuracy can be changed from the millimeter level, navigation accuracy average of less than 2 mm, and is available for user secondary development package, free easy programming operation, combined with surgical instruments and flexible, easy to implement intelligent navigation surgery. For clinical work provides an updated, more broad application space, enhancing the overall surgical navigation accuracy and controllability.
