Biochemical electroencephalogram synchronous monitoring cortical electrode

Abstract

The invention relates to a biochemical electroencephalogram synchronous monitoring cortical electrode which comprises a strip-shaped substrate, a plurality of microdialysis tubes and a plurality of electrode points connected through electrode guide wires, and the electrode points and the microdialysis tubes are all arranged on the same surface of the substrate. When the biochemical electroencephalogram synchronous monitoring cortical electrode is put into the intracranial cortical layer of a patient, a brain wave signal can be received by the substrate and the combination of the electrode points connected through the electrode guide wires, so that electrophysiology monitoring is realized; and meanwhile, the plurality of microdialysis tubes can obtain brain tissue extracellular fluid, so that biochemical monitoring is realized. According to the biochemical electroencephalogram synchronous monitoring cortical electrode, electrophysiological monitoring and biochemical monitoring can be carried out at the same time, so that medical staff can more accurately observe physiological, pathological and behavioral changes, and the accuracy of obtaining the measurement result of the physiological, pathological and behavioral changes of the intracranial cortical layer of the patient can be improved.

Description

technical field [0001] The present application relates to the field of EEG microelectrodes, in particular to a cortical electrode for synchronous monitoring of biochemical EEG. Background technique [0002] At present, electrophysiological monitoring methods are commonly used in neurosurgery to record or measure changes in membrane potential, conduction velocity, and ion channel activities in intracranial tissues, nerves, and cell ion channels. Electrophysiological monitoring can be recorded and measured by instruments such as electrophysiological instruments and microelectrodes. [0003] During treatment, in addition to monitoring changes in membrane potential, conduction velocity, and ion channel activity in intracranial tissues, nerves, and ion channels to observe changes in physiology, pathology, and behavior, biochemical monitoring can also be performed, that is, monitoring such as Brain cell energy metabolism-related substances, free radical-related substances, amino ...

AI Technical Summary

Problems solved by technology

[0004] Although when electrophysiological monitoring is performed on the patient's intracranial cortex alone, the measurement results of physiological, pathological and behavioral changes can reflect the occurrence of the disease and the effect of treatment after analysis, but the accuracy of the measurement results needs to be improved.
