What are the domestic and international EMC (electromagnetic compatibility) standards for surgical navigation systems?

Surgical navigation systems integrate optical/electromagnetic positioning, image processing, and display, and must meet GB 9706.1, YY 0505 (domestic), and IEC 60601-1-2 (international) EMC standards. Their precise positioning function is susceptible to electromagnetic interference from metallic objects and other electronic devices (especially those containing motors) in the environment. The standards require that the system's positioning accuracy not decrease due to electromagnetic interference in a typical operating room environment, while the system's own emissions (e.g., computer, monitor) must not exceed limits. For electromagnetic positioning systems, the anti-interference capability of their operating frequency band is a key testing focus.
