RESUMO
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. Methods: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 Jingzhou City, First People's Hospital conducted a series of clinical application, verify the advantages of the system, allows doctors during 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.
