Problems solved by technology

The disadvantage is that the pulse parameters (including pulse amplitude, pulse width, and cycle) can only be roughly adjusted, divided into several to dozens of levels; the pulse parameter error is large, reaching ±25% or even higher; after the pulse generator is implanted in the body, the soft The hardware cannot be changed. Once there is any failure due to external reasons, or the software needs to be upgraded, it must be removed and replaced by surgery, which will not only increase the pain of the patient, but also increase the economic burden.

Embodiment Construction

[0032] In order to achieve the above object, the technical solution of the present invention is realized by the following solution: an implantable electrical nerve pulse stimulation system, comprising a pulse generator and electrodes implanted in the human body, the pulse generator includes a microprocessor and a digital-analog A converter, the digital-to-analog converter converts the digital signal output by the microprocessor into an analog signal, so as to output stimulation electrical pulses with adjustable parameters to the electrodes.

[0033] The shell of the pulse generator of the present invention can be made of biocompatible pure titanium, stamped and formed, and sealed by laser welding.

[0034] Further, the pulse generator may include a programmable current source, and the output current value of the programmable current source is controlled by the analog signal, so as to provide the electrodes with adjustable stimulating electric pulses.

[0035] Further, the puls...

Abstract

An implanted electric pulse system for stimulating nerve to treat Parkinson's disease, epilepsy, pain, strain and spasm is composed of a pulse generator implanted in human body, leading lines, electrodes, external program controller, PDA and external control magnet. The working state of pulse generator and the pulse parameters can be remotely controlled and regulated by said external magnet, program controller and PDA. The software update can also be performed through PDA and program controller.

Description

technical field [0001] The invention relates to an implanted nerve electrical pulse stimulation system for treating nervous system diseases through electrical pulse stimulation to targets, 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. [0003] Chines...
