Multi-target electric stimulation circuit, electric stimulator and signal output method thereof

Abstract

The invention discloses a multi-target electric stimulation circuit, an electric stimulator and a signal output method thereof. The electric stimulation circuit includes a control module, a plurality of EEG acquisition modules and a plurality of stimulation adjustment modules, and each electrode is correspondingly provided with a brain The electrical acquisition module and a stimulation adjustment module, different electrodes are used to stimulate different targets; the EEG acquisition module is used to collect the EEG signals on the corresponding electrodes and transmit them to the control module; the control module is used to The electrical signal obtains the brain rhythm phase signal, and outputs the stimulation signal at the set waveform phase point after phase-locking the brain rhythm phase signal; the stimulation adjustment module is used to adjust the brain electrical stimulation signal output to the corresponding electrode according to the received stimulation signal . Through the technical solution of the invention, it is beneficial to realize electrical stimulation to multiple targets, and realize time-locked matching of electrical stimulation to multiple target points.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of medical devices, in particular to a multi-target electric stimulation circuit, an electric stimulator and a signal output method thereof. Background technique [0002] In recent years, with the development of neuroimaging technology, the advancement of brain signal analysis methods and the breakthrough of medical concepts, some brain diseases have shown new common features in terms of pathogenesis and treatment methods, and gradually formed new disease groups. Called brain function disease. Such diseases have abnormal brain network characteristics, which can be adjusted by electrical stimulation, thereby changing the abnormal brain network characteristics and clinical symptoms. The concept of brain function diseases has opened up a new field of clinical diagnosis and treatment, and has brought hope to brain diseases that have been in a difficult diagnosis and treatment for a long...

Problems solved by technology

However, RNS can only achieve a maximum of two targets, that is, the electrical stimulation of two key brain regions, and cannot perform whole-brain regulation of brain function diseases with multiple neural circuits, and the stimulation of the two targets cannot be time-locked. , that is, the two targets cannot be stimulated simultaneously or sequentially at fixed time intervals
