Example Embodiment

[0034] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0035] figure 1 As shown in the schematic diagram of applying the present invention to bilateral deep brain stimulation, the dual-channel implantable neurostimulator 1 of the present invention generates two electrical impulse signals, and transmits the two electrical impulse signals to the two through two extension wires 2. Two stimulating electrodes 3 and two stimulating electrodes 3 add two electrical pulse signals to two therapeutic targets respectively, and play a role in treating neurological diseases through electrical pulse stimulation.

[0036] The two electrical pulse signals generated by stimulator 1 are as figure 2 As shown, the pulse amplitude and pulse width of channel 1 and channel 2 can be adjusted independently. The frequency of the two channels is the same, and they are separated in time sequence. After each electrical stimulation pulse ...

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 ...
