Problems solved by technology

However, from the perspective of hardware, the traditional deep brain stimulation and detection not only requires stimulation electrodes, but also an electrophysiological detection system that is closely attached to specific nerve cells, which causes the complexity of the operation and is more likely to cause related adverse events. complication
Moreover, the mechanism of action of deep brain electrical signal stimulation therapy is not yet fully understood. Not only are there many unresolved issues, but it may also cause adverse reactions related to surgery, hardware, and stimulation.

Abstract

The invention relates to a probe for deep brain electromagnetic coupling stimulation and electric signal detection, and belongs to the technical field of infrared / terahertz. The probe comprises a probe tubular structure and a probe end seal. The probe tubular structure is sequentially composed of a probe shell, a polycarbonate insulating sleeve layer, a brass sleeve layer, a polycarbonate base layer, a silver film and a silver iodide film from the outer side to the inner side. The brass sleeve layer extends out of the probe tubular structure to form a probe tip; an optical fiber lens is embedded in the probe tip; and the tip of the probe tip is sealed with cycloolefin resin. The probe provided by the invention not only can couple a high-frequency electromagnetic signal into a specific target in the brain of a higher animal, but also can cling to nerve cells of the target to carry out real-time electric signal detection on the stimulation effect. The deep brain electromagnetic stimulation probe can provide an efficient, minimally invasive and high-targeting stimulation mode and can accurately detect the action potential of a functional area to finally achieve more effective deep brain electromagnetic stimulation and detection.

Description

technical field [0001] The invention relates to a probe for deep brain electromagnetic coupling stimulation and electric signal detection, which belongs to the field of infrared / terahertz technology. 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 high-frequency electrical stimulation in specific parts of the deep brain, thereby changing the corresponding nuclei. To improve the symptoms of Parkinson's disease, essential tremor, torsion spasm, epilepsy and obsessive-compulsive disorder, severe depression, severe anxiety and phobia, anorexia nervosa, spastic torticollis, Tourette's syndrome, etc. A neurosurgical therapy. DBS has the advantages of good selectivity, clear target, minimally invasive, adjustable, reversible, etc. It needs to stimulate different deep brain functional areas for different neurological diseases. Exi...
