The product is designed for intraoperative monitoring; monitoring is flexible and multi-modal which comprises of SEP/efferent pathway, tcMEP/efferent pathway, ABR/auditory nerve function, facial nerve mapping and spontaneous EMG. There are 16 or 32 channel amplifiers which can be chosen to attain waveforms. The waveform acquisition and stimulation is done by compact distinct breakout boxes which can be kept at the head or foot of the bed which helps in eliminating extension cords and long electrode wires. The device can freely control up to 22 stimulation sites with the help of optional extension units. High or low current pulses can be produced from the extension units. Operation images can be stored with the waveforms. Using optional camera capture unit, microscopic images are displayed. The NeuroWorkbenchTM SQL database combines all the Nihon Kohden's neurology devices in order to offer entire database throughout the neuro-diagnostic and monitoring modalities.
