Double-channel embedded nerve stimulator

Abstract

The invention discloses a double-channel embedded nerve stimulator which belongs to the technical field of embedded medical instruments. Two-way stimulating signals can be simultaneously produced forsimultaneously stimulating two target points of brain or nerve, thereby effectively controlling and treating diseases. The double-channel embedded nerve stimulator comprises a microcontroller, a double-channel pulse output circuit, a communication circuit, a power management circuit, a battery and the like, wherein a program memory, a digital-analog signal converter, a timer and the like are integrated in the microcontroller; the double-channel pulse output circuit comprises a DC-DC circuit, an output channel, a polarity selection circuit, a pulse output control circuit, a charge balance circuit and an electrode impedance measurement circuit; the communication circuit comprises a communication coil, a signal transmission circuit and a signal reception circuit; and the power management circuit is connected with the battery. A power supply is a primary battery or a charging battery capable of meeting different application requirements and exerting respective use advantages. Compared witha single-channel product, the double-channel embedded nerve stimulator doubles the treating capability and has high economic and social benefits.

Description

technical field [0001] The invention relates to a dual-channel implantable nerve electric pulse stimulator capable of treating nervous system diseases by simultaneously stimulating electric pulses on two 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 ...

AI Technical Summary

Problems solved by technology

[0005] Since the nerve stimulator achieves therapeutic effects through electrical pulse stimulation of the target, the power supply is an important unit of the implantable nerve stimulator. The present invention uses a battery as the power supply. The battery used can be a traditional disposable battery or a lithium battery. Ion rechargeable battery, the advantage of using a primary battery is that the circuit is simple and easy to use, but the disadvantage is that the life is limited by the battery capacity. Once the battery energy is exhausted, the patient has to undergo surgery again and replace the stimulator; Small, the disadvantage is that the circuit is relatively complicated, the cost is high, and wireless charging needs to be performed regularly
