摘　　要：目的:设计开发一种由微处理器控制、可利用脑电信号来进行调幅的小脑顶核电刺激仪。方法:采用高共模抑制比的前置放大器以及多种滤波手段,保证较理想的获取脑电信号。输入输出部分采用光耦元件,实现电气隔离,保证安全。结果:开发的仪器克服了刺激波对机体的适应性问题,能够安全、有效、无创地治疗缺血性脑血管疾病。结论:小脑顶核电刺激能有效治疗缺血性脑血管疾病,同时采用脑电信号调幅,能够很好地克服机体对刺激信号的适应性。Objective To design an electrostimulator for cerebellar fastigial nucleus stimulus, which is controlled withsinglechip system and using EEG（Electroencephalogram）to modulate amplitude of the carrier wave. Methods The EEG with instrumentation amplifier of high CMRR （Common Mode Rejection Ratio） and some filters are collected. The electric insulation is achieved by using linear optocouplers on the parts of input and output. Results The stimulator can solve the problem of adaptability for wave to simulate the body, and is safe, non-invasive, and of obvious therapy for ischemic cerebrovascular disease. Conclsion The cerebellar fastigial nucleus stimulus can cure ischemic cerebrovascular disease obviously, and the modulation with EEG can solve the problem of adaptability for wave to simulate the body.
