Abstract:
Objective In order to meet the needs of more precise surgical navigation during interventional procedures and minimally invasive surgery, Aurora electromagnetic tracking technology-assisted surgical navigation with free combination of various surgical instruments was tested, trying to further solve problems encountered in surgery. Methods Aurora electromagnetic tracking system was used to match the medical surgical environment with metal-containing material. The built-in control software in this electromagnetic tracking system, which was equipped with the software development kit, was used to write a set of VC programming language suitable for real-time display of clinical surgical navigation system, and relative performance tests and comparative experiments were conducted for different medical surgical navigation application in the hospital to measure the precision degree of the tracking system, as well as the statistics of various surgical instruments corresponding to the application in different surgeries. Results 160 patients in interventional surgery with coronary angiography were randomly selected, 80 patients treated by digital subtraction angiography(DSA) with electromagnetic tracking systems as the experimental group, and 80 patients by DSA only as the control group. It was found out that with obviously less operating time, the amount of contrast agent was significantly reduced in the experimental group, and the degree of controllability for interventional surgical procedure was increased from 95% success rate to 99%. Conclusions The comparative experiments proved that Aurora electromagnetic tracking technology could significantly improve the accuracy in surgery, with the mean value of navigation less than 2 mm. In terms of interventional procedures and minimally invasive surgery, this electromagnetic tracking technology can greatly relieve patients' suffering and reduce medical risks to make medical care safer, and enhance the surgical technology level in hospital.
