Problems solved by technology

The pulse signal generated by the stimulator can have two modes of constant voltage and constant current. The neural stimulators in the prior art generally only have one pulse mode, and the two output modes of constant voltage and constant current have their own characteristics. The constant voltage mode The circuit is simple, the power consumption is relatively low, the current output in the constant current mode is stable, but the power consumption is relatively large, and the two pulse modes can meet different application requirements

Embodiment Construction

[0029] figure 1 As shown in the schematic diagram of application of the present invention to bilateral deep brain stimulation, the implantable neurostimulator 1 of the present invention generates two circuits of constant voltage or constant current electric pulse signals, and the two circuits of electric pulse signals are transmitted to Two stimulating electrodes 3, the two stimulating electrodes 3 apply two electrical pulse signals to two treatment targets respectively, and the neurological diseases can be treated by electrical pulse stimulation.

[0030] The stimulator 1 can generate one or two electrical pulse signals through programming, figure 2 Shown is the pulse signal when two pulse outputs are generated. The amplitude and pulse width of channel 1 and channel 2 pulses can be adjusted independently. The frequency of the two channels is the same and separated in time sequence. After the pulse output, after a short time delay (about 200uS), a reverse low-amplitude pulse...

Abstract

The invention discloses an embedded nerve stimulator with a constant voltage / constant current dipulse mode, belonging to the technical field of an embedded medical instrument. The embedded nerve stimulator provides a two-channel embedded never electric pulse stimulator for patients suffered from nerve system disease and can generate one or two electric pulse signals simultaneously, wherein the electric pulse signal(s) can be an electric pulse signals mode or a constant current pulse mode, and the two pulse modes can be switched by external program control equipment. The embedded nerve stimulator is characterized in that the embedded nerve stimulator mainly comprises a microcontroller, a pulse output circuit, a communication circuit, a power management circuit, a battery and the like. The embedded nerve stimulator has the constant voltage / constant current dipulse mode, so that the applicability problem of different application requirements can be solved, and the cure requirement of various system diseases can be met. The embedded nerve stimulator can be used for curing various nerve system diseases.

Description

technical field [0001] The invention relates to an implantable nerve electric pulse stimulator capable of stimulating a target point through two pulse modes of constant voltage and constant current, and belongs to the technical field of implantable medical instruments. Background technique [0002] For certain types of neurological diseases, such as Parkinson's disease, epilepsy, intractable pain, torsion spasm, spastic torticollis, chorea, idiopathic vertigo, clinically commonly used drug therapy and surgical treatment, but side effects and complications Symptoms are important disadvantages. Electrical stimulation therapy performs chronic electrical pulse stimulation on the corresponding targets of different diseases, such as stimulating the subthalamic nucleus and globus pallidus for Parkinson's disease, stimulating the vagus nerve for epilepsy, and playing a therapeutic effect on the cause. It is a reversible neuromodulation Treatment is an ideal treatment method. [00...
