Abstract:
1. An evoked spinal cord potential monitoring system for monitoring spinal cord ischemia during an operation, comprising evoked spinal cord potential monitoring apparatuses attached respectively to an exposed upper intercostal nerve and an exposed lower intercostal nerves, wherein: each of the evoked spinal cord potential monitoring apparatuses includes a pair of electrodes; and a holding section for holding the pair of electrodes, a tip section of each of the electrodes being extended outwards from an end of the holding section, and the electrodes being movable relative to the holding section; and a hook section engageable to the exposed upper intercostal nerve or the exposed lower intercostal nerve is provided at the tip section of each of the electrodes, the hook section is engaged to the intercostal nerve such that the hook section and the holding section are able to hold the intercostal nerve therebetween wherein the evoked spinal cord potential monitoring apparatus configured to be attached to the exposed upper intercostal nerve includes an electric stimulation section, and the evoked spinal cord potential monitoring apparatus configured to be attached to the exposed lower intercostal nerve includes a recording section for recording electric signals conducted from the spinal cord to the lower intercostal nerve as waveforms, wherein the electric stimulation section comprises a pulse generator and the recording section comprises a digital oscilloscope and a processing section wherein the holding section includes therein an electric connection section to the electrodes wherein the electric connection section includes: a stereo jack, and an electrode cable for connecting the stereo jack and the electrodes and wherein the recording section records trans-intercostal evoked spinal cord potentials.
