Pacemaker and pacemaker electrode

Abstract

The invention provides a pacemaker and a pacemaker electrode. The pacemaker electrode comprises a body and an insulation layer. The body comprises at least one carbon nano tube line which has a plurality of carbon nano tubes arranged axially along the body and connected end to end by a Van der Waals' force; and the insulation layer is coated on the outside surface of the body. The pacemaker comprises a pulse generator, a connecting wire and the pacemaker electrode.

Description

technical field [0001] The invention relates to a pacemaker and a pacemaker electrode thereof, in particular to a carbon nanotube-based pacemaker and a pacemaker electrode thereof. Background technique [0002] Parkinson's disease is a chronic disorder of the central nervous system. The cause is still unknown. It is speculated that it is related to the rapid degeneration of brain cells and the inability to produce enough neurotransmitter dopamine (Dopamine). Because dopamine substances are needed in the brain to command muscle activity, lack of dopamine will cause symptoms of movement disorders in patients, such as tremor, stiffness, slow movement, etc., which in turn affects the quality of life of patients. [0003] At present, in addition to drug treatment for Parkinson's disease, patients can also use surgical implantation of a brain pacemaker (brain pacemaker) to alleviate the patient's discomfort, and the brain pacemaker transmits electrical pulses to stimulate brain ce...

Problems solved by technology

[0005] Since the pacemaker electrodes 11 in the prior art are made of platinum metal electrode wires, (1) the price is relatively expensive; (2) the elasticity is insufficient, and it is easy to cause damage to human tissues during activities; (3) the platinum metal wires are made of The thinner the wire is, the higher its resistivity will be, which will weaken the electrical pulse signal and affect the therapeutic effect; (4) Under the existing technology, the platinum metal wire cannot be made very thin (such as less than 10 microns), so it can be implanted at the same time. The number of electrode wires inserted into the human body is limited, so that the area that can be treated at the same time is limited, which affects the treatment effect; (5) Platinum metal has weak corrosion resistance, and it is prone to poor contact during long-term activities of the human body and under the corrosion of body fluids. Phenomena that shorten the life of the pacemaker or reduce the effectiveness of the therapy
