Medical devices are categorized into Class 1, Class 2 and Class 3 according to the degree of risk from low to high.
The first class of medical devices need to obtain the "Class I Medical Device Record Certificate"; the second and third class only need to obtain the "Medical Device Product Registration Certificate".
Therefore, pathology slicers and other pre-processing equipment for pathology sample analysis need to obtain a "Class I Medical Device Record Certificate", not a registration certificate.
