Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. The accompanying drawings are exemplary and are only used to explain the present invention, rather than being construed as limiting the present invention.

[0036] Such as figure 1 As shown, this figure shows all the modules of the present invention, mainly including three parts, the subject, the deep brain stimulator and the PC (optional). The subject is a patient, and the patient's brain is implanted with a special electrode in advance, and the electrode is connected to the deep brain stimulation instrument developed by the present invention through a 2.5mm plug hole. The deep brain stimulation instrument (system) includes four modules: acquisition and recording circuit module, data algorithm main control circuit module, waveform output and stimulation circuit module, and power supply voltage stabilization module. This block diagram mainly shows that t...

Abstract

The invention belongs to the field of medical clinical technology, in particular to a portable closed-loop deep brain stimulator system with an intelligent self-adaptive function. The system of the present invention has 16 channels of data acquisition and 4 channels of stimulation. Among the acquisition channels, 4 channels are used for intracranial LFPs acquisition, and 12 channels are used for extracranial signal acquisition; the output voltage of the stimulation channel is an arbitrary waveform that can be modulated. Applying stimulation while recording can effectively reduce the influence of stimulation artifacts on recording signals and stabilize the driving voltage. The system circuit mainly includes MCU main control circuit, LFPs acquisition channel and external acquisition channel switch circuit, low-amplitude voltage isolation input circuit, low-pass filter, high-pass filter and power frequency filter, A / D conversion acquisition circuit, WIFI communication, four-channel output D / A circuit, voltage isolation output drive circuit, current detection protection circuit, SD storage, etc. The system circuit of the invention has the advantages of compact structure, extremely low power consumption and stable operation, and the instrument is only the size of a palm and is convenient to carry.

Description

technical field [0001] The invention belongs to the field of medical clinical technology, and in particular relates to a portable closed-loop deep brain stimulator system (IDBS) with an intelligent self-adaptive function. Background technique [0002] In recent years, deep brain stimulation therapy has become more and more widely used clinically, and it has become a treatment for Parkinson's disease, dystonia, epilepsy, tremor and other diseases, as well as pain and some mental diseases. Due to the advantages of non-destructive, micro-injury, recoverable and adjustable, deep brain stimulators have become the first choice for surgical treatment of PD diseases. [0003] Closed-loop deep brain stimulation treatment methods have received extensive attention and clinical research in the medical field. At present, compared with other treatment methods, such as drug therapy, deep brain stimulation devices have obvious advantages, such as less damage to cell tissue and fewer complic...
