Abstract

The invention provides a brain deep stimulation device combining high-frequency electromagnetic waves and electric pulses. The device comprises a cylindrical metal inner core, an annular dielectric layer coating the cylindrical metal inner core and a metal tube located outside the dielectric layer. A metal lead is led from a side surface of the cylindrical metal inner core, the metal lead is connected to an external power supply, and the cylindrical metal inner core is used for conducting electric pulse stimulation. One end of the cylindrical metal inner core close to an action target is a signal output end, and the signal output end is a first tapered conical structure and is used for inserting a tested object, the other end of the cylindrical metal inner core is a signal input end connected to an input fiber and is used for receiving the high-frequency electromagnetic waves inputted into the cylindrical metal inner core by the input fiber. A coaxial waveguide structure is formed between the cylindrical metal inner core and the metal tube and transmits the high-frequency electromagnetic waves through the dielectric layer. The invention introduces a high-frequency electromagnetic field into the deep part of a brain to apply stimulation, the high-frequency electromagnetic waves and the electric pulses are combined to stimulate the deep part of the brain, and the deep brain stimulation effect is improved.

Description

technical field [0001] The invention relates to the technical field of deep brain stimulation, in particular to a deep brain stimulation device combining high-frequency electromagnetic waves and electric pulses. Background technique [0002] Deep brain stimulation (DBS) is the fastest-growing technology in the field of neurosurgery in the past 20 years. It uses stereotaxic methods for precise positioning, and implants stimulating electrodes at specific targets in the brain for high-frequency electrical stimulation. It is a neurosurgical therapy that changes the excitability of the corresponding nuclei to improve the symptoms of Parkinson's disease, control epileptic seizures, and relieve pain. The neuropsychiatric diseases that can be treated by DBS include: Tourette syndrome, obsessive-compulsive disorder, depression, impulsive behavior, obesity substance addiction and anorexia nervosa, etc. In addition, it can treat chronic pain, headache, epilepsy, vegetative state, Alzhe...
