Whether the active medical device accessories need to betested for EMC has nothing to do with the connection form of theproduct, which mainly depends on their influence of the product'selectromagnetic compatibility. For example, the wireless foot switchthat controls the operation of the device generally needs to be testedfor EMC, while the ultrasonic probe puncture rack that is purelyphysically connected and does not contain electronic componentsgenerally does not need to be tested for EMC.
