Nerve stimulation electrode, nerve stimulation device and nerve stimulation system

Abstract

The invention provides a nerve stimulation electrode, a nerve stimulation device and a nerve stimulation system.The nerve stimulation electrode comprises an electrode shell, the electrode shell comprises a hollow tube and a stimulation head end, the stimulation head end is arranged in the electrode shell, and the hollow tube is arranged in the electrode shell; the electrode shell is provided with a stimulation head end, the stimulation head end is used for conducting electrical stimulation energy to the surface of tissue to electrically stimulate the tissue and collecting electrical signals of the tissue, the stimulation head end can move in the electrode shell in the axial direction of the electrode shell, and / or the stimulation head end is used for conducting electrical stimulation energy to the surface of the tissue to conduct electrical stimulation energy to the surface of the tissue. The stimulation head end can rotate in the electrode shell in the circumferential direction of the electrode shell. According to the nerve stimulation electrode provided by the invention, electrical stimulation can be carried out on different parts of the organism tissue by using fewer stimulation contacts, and accurate stimulation is realized by collecting and analyzing electrical signals of different parts.

Description

technical field [0001] The present application relates to the field of implantable medical devices, in particular to nerve stimulation electrodes, nerve stimulation devices and nerve stimulation systems. Background technique [0002] The nerve stimulation electrodes of the prior art interventional nerve stimulation devices usually have a plurality of fixed stimulation contacts. During the operation, the medical staff implants the electrodes into the tissue such as the brain according to the existing knowledge and experience of the specific disease. A specific area can be electrically stimulated to achieve the purpose of treating certain diseases. Usually, in order to obtain a better combination of stimulation directions and points, the stimulation contacts will be preset as many as possible, for example, 8 contacts, 12 contacts, 24 contacts, etc., and set accordingly for each stimulation contact Connect wires to deliver electrical stimulation energy. However, due to the sm...

AI Technical Summary

Problems solved by technology

However, due to the small space in the nerve stimulation electrodes, it is difficult to set too many stimulation contacts and corresponding lines, and thus limits the flexibility of the doctor's identification of disease sites and theoretical research and treatment of more stimulation contact sites
