Embodiment Construction

[0033] The implantable electrical nerve stimulation system provided by the present invention may be a deep brain electrical stimulator, a vagus nerve stimulator, a peripheral nerve stimulator or other similar stimulator systems. Embodiments of the present invention are described by taking an implantable deep brain electrical stimulator as an example.

[0034] figure 1 The present invention shown is applied to the schematic diagram of bilateral deep brain stimulation. The implantable neurostimulator 1 of the present invention generates two paths of constant voltage / constant current electrical pulse signals after envelope modulation. The two electrical pulse signals are transmitted to the two stimulation electrodes 3, and the two electrical pulse signals are applied to the two treatment targets respectively, and the neurological diseases are treated by the electrical pulse stimulation.

[0035] Such as figure 2 As shown, in an embodiment of the present invention, a rechargeab...

Abstract

The invention discloses an implanted type electrical nerve stimulation system with a modulation mode, and belongs to the technical field of an implanted type medical instrument. The system comprises a waveform generator, a stimulation electrode and an external program control instrument for program control of the waveform generator. A control module included by the waveform generator can carry out envelope modulation on output 2-250Hz constant-voltage / constant-current electric impulse stimulation. Modulation envelope waveform features are set through the external program control instrument, and the envelope frequency is usually 1 to 10Hz. Shapes of envelope waveforms can be randomly set, and the control module finishes fitting reconstruction of the envelope waveforms in the control module through a function reconstruction method. The implanted type electrical nerve stimulation system provided by the invention provides a new treatment method for a patient with a neurological disease through introduction of the envelope modulation.

Description

technical field [0001] The invention relates to an implantable nerve electric pulse stimulator capable of performing envelope modulation on two pulse modes of constant voltage and constant current to stimulate a target point, 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 drawbacks. Electrical stimulation therapy chronically stimulates the corresponding targets of different diseases, such as stimulating the subthalamic nucleus and globus pallidus for Parkinson's disease, and stimulating the vagus nerve for epilepsy. , is an ideal treatment. [0003] The implantable neurostimulation system usually consists of a neurostimulator implanted in t...
