What are the domestic and international EMC (electromagnetic compatibility) standards for ENT treatment units?

The ENT treatment unit integrates various devices such as endoscopic displays, suction devices, microscopes, and electric drills. Its EMC standards must meet GB 9706.1, YY 0505 (domestic), and IEC 60601-1-2 (international). As the power supply and control center for various devices, the standard requires that the interference generated by its internal units (especially the suction device and electric drill with motors) during operation should not affect the image quality of the endoscopic camera system and the display. At the same time, the interference of the entire treatment unit to the power grid should be within the limits, and it should be able to operate stably in the electromagnetic environment of the examination room.
