The invention discloses a controllable deep brain stimulation waveform generation method. The method comprises the steps: a first waveform signal is obtained through an upper computer, signal parameters of the waveform signal are obtained, and the first waveform signal is an analog waveform signal; the upper computer sends the signal parameters to a lower computer, the lower computer generates a second waveform signal according to the signal parameters, and the second waveform signal is a waveform signal used for deep brain stimulation; and the lower computer sends the second waveform signal to an oscilloscope for synchronous display. Only required waveforms need to be simulated on the upper computer, then the signal parameters are determined and sent to the lower computer, and the lower computer generates the specified stimulation waveform signal and sends the stimulation waveform signal to the oscilloscope for display after receiving the signal parameters; the different signal waveforms can be simulated on the upper computer according to requirements, so that the controllability of subsequent output waveforms is realized; and the waveforms can be synchronously displayed in a visual upper computer interface of an operator and the oscilloscope so as to check whether data transmission is consistent or not, and the accuracy of the finally generated waveforms is improved.
Description
technical field [0001] The present application relates to the technical field of bioengineering, in particular to a method for generating controllable deep brain stimulation waveforms. Background technique [0002] Deep brain stimulation is to generate corresponding stimulation signals through signal generation equipment, and then stimulate neurons in the brain through the stimulation signals. The general application of traditional technology is open-loop high-frequency pulse signal, the parameters of the generated signal are fixed, and the signal strength cannot be changed. [0003] However, the existing open-loop fixed-parameter stimulation signals easily lead to damage to the stimulation target, excessive energy consumption of the system, and the parameters cannot be adaptively adjusted according to the improvement of neuron symptoms. Moreover, the stimulation effect of closed-loop stimulation or other stimulation waveforms is better than that of deep brain stimulation w...
