What are the domestic and international EMC standards for hysteroscopic systems?

Similar to laparoscopy, hysteroscopic systems are used for intrauterine examinations and surgeries. Their EMC standards must also meet GB 9706.1, YY 0505 (domestic), and IEC 60601-1-2 (international). A key difference is the use of fluids (e.g., mannitol, glucose solution) for uterine distension, requiring control of the irrigation fluid's pressure and flow rate. Therefore, the system includes an irrigation pump and a pressure monitoring unit. Standards require that these fluid control units operate independently of the camera and lighting systems, ensuring precise control of intrauterine pressure even when using equipment such as electrosurgical units, thus guaranteeing surgical safety.
