Nerve electrical stimulation system capable of being provided with plurality of implanted electrodes

Abstract

The invention relates to a deep brain electrical stimulation system, in particular to a nerve electrical stimulation system capable of being provided with a plurality of implanted electrodes. The nerve electrical stimulation system comprises a pulse generator, extending conducting wires, electrodes and fixing devices, wherein the pulse generator is a multi-channel multi-contact pulse generator; the extending conducting wires are connected with the multi-channel multi-contact pulse generator through contacts; the electrodes are connected onto the extending conducting wires; and the fixing devices are used for fixing the electrodes in the use process. The nerve electrical stimulation system has the advantages that the matching relationship between the quantity of pulse contacts and the quantity of the electrodes can be regulated according to the precision requirement of the system, so that the multi-channel multi-pulse electrical stimulation output is realized; and by regulating the structures of the extending conducting wires, the quantity of the electrodes can also be increased according to requirements under the condition that the quantity of the pulse contacts is not changed, sothat the requirement of more complicated electrode stimulation is met.

Description

Technical field [0001] The invention relates to a deep brain electrical stimulation system, in particular to a nerve electrical stimulation system that can be equipped with multiple electrodes. Background technique [0002] Implantable neurostimulation therapy has been widely used clinically because of its effectiveness and reversibility in treating neurological diseases. Deep brain electrical stimulation is a typical application of implanted nerve electrical stimulation. A pulse generator implanted in the body generates stimulation pulses. The stimulation signals are transmitted to the connecting parts in the top cover through the feedthrough connector. The cover part is connected to an extension wire through an internal connector, and then the extension wire is connected to the electrode, and the stimulation signal is output to the brain target position, thereby achieving the purpose of treatment. [0003] However, the current deep brain electrical stimulation techniques only im...

Problems solved by technology

[0004] However, with the further expansion of therapy and the further improvement of curative effect requirements, the current plan of implanting a maximum of two electrodes can no longer meet the requirements of the current treatment plan.

For this problem, the existing technology has provided a solution to provide more implanted electrodes by adding pulse devices, but this method will also cause a series of problems, such as high surgical costs, at least doubled, and lead to The probability of patient rejection and infection is greatly increased. Therefore, it is not a feasible solution to solve the above problems by adding pulse generators.
