Spinal cord injury condition monitoring method based on somatosensory evoked potential signal

Abstract

The invention relates to a spinal cord injury condition monitoring method based on a somatosensory evoked potential signal, which is mainly and technically characterized by comprising the following steps: step 1, obtaining the somatosensory evoked potential signal, decomposing the somatosensory evoked potential signal on a time domain and a frequency domain by adopting a short-time Fourier transformation method to obtain a time domain signal and a frequency domain signal; step 2, carrying out abnormal early warning judgment according to the change rate of the somatosensory evoked potential signal on the time domain signal and the frequency domain signal. The spinal cord injury condition monitoring method has the benefits that the somatosensory evoked potential (SEP) signal is decomposed into the time domain signal and the frequency domain signal, and the change rate of the somatosensory evoked potential signal is monitored, so that the function of monitoring the spinal cord injury condition is automatically realized, the problem of error caused by incomplete criterion in the prior art is solved, the monitoring accuracy is improved, the judgment error is reduced, and the judgment time is effectively shortened; meanwhile, an early warning can be technically sent out if the abnormal situation occurs, so that the occurrence of spinal cord injury accidents is prevented.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a spinal cord injury monitoring method based on somatosensory evoked potential signals. Background technique [0002] Spinal surgery is a high-risk operation. In spinal surgery (such as spinal deformity surgery) and cardiac surgery (such as aortic aneurysm surgery), spinal cord injury is often caused by spinal cord ischemia or mechanical traction / compression. Mild cases of this kind of injury can cause quadriplegia, and severe cases may cause hemiplegia, paraplegia or even life-threatening. Therefore, intraoperative spinal cord monitoring has become a necessary routine monitoring method. The spinal cord monitor is an instrument for monitoring and evaluating spinal cord injury during spinal cord surgery. It uses the spinal cord somatosensory evoked potential (SEP) method to monitor and evaluate nerve damage. [0003] The existing spinal cord somatosensory evoked potential...
