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 comprises a control module, a pluralityof electroencephalogram acquisition modules and a plurality of stimulation adjustment modules, wherein each electrode is correspondingly provided with one electroencephalogram acquisition module andone stimulation adjustment module, and different electrodes are used for stimulating different targets; the electroencephalogram acquisition modules are used for acquiring electroencephalogram signalson the corresponding electrodes and transmitting the electroencephalogram signals to the control module; the control module is used for acquiring a brain rhythm phase signal according to the receivedelectroencephalogram signals, and outputting a stimulation signal at a set waveform phase point after phase locking is carried out on the brain rhythm phase signal; and the stimulation adjustment modules are used for adjusting an electroencephalogram stimulation signal output to the corresponding electrodes according to the received stimulation signal. Through the technical scheme of the invention, electric stimulation for multiple targets is facilitated, and time-locking matching for electric stimulation for multiple targets is realized.

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
