Helmet-type low-intensity focused ultrasound stimulation device and system

Abstract

A helmet-type low-intensity focused ultrasound stimulation device, according to the present invention, comprises: a first guide part which is formed in an arc shape and is provided in the longitudinal direction; a second guide part which is formed in an arc shape and is connected in a transverse direction so as to be perpendicular to the first guide part; an ultrasound module which is connected to the second guide part and includes a transducer for generating ultrasound waves moving towards an inner direction; and a support part which is worn on the head of a user, and to which the first guide part is fixed and both end portions of the second guide part are rotationally fixed, wherein the second guide part rotates in a longitudinal direction by allowing one point thereof to be guided along the first guide part, and the transducer is capable of moving in a transverse direction along the second guide part.

Description

technical field [0001] The invention relates to a helmet-type low-intensity ultrasonic focused stimulation device, in particular to a device for stimulating a user's head by using focused ultrasonic waves. Background technique [0002] Methods for regulating brain function include brain cell activation by drugs, electrical stimulation by probes, and transcranial magnetic stimulation. [0003] However, there is a problem that only a desired specific site cannot be regulated by a drug in the way of activating brain cells by a drug. For electrical stimulation using a probe, the probe can be transplanted or inserted into a specific position of the brain by using electrocorticogram (Electrocorticogram) for brain surgery or deep brain stimulation (Deep brain stimulation: DBS), And perform electrical stimulation to temporarily or permanently change brain function, but it will be accompanied by dangers based on invasive methods. Also, the transcranial magnetic stimulation method i...

Problems solved by technology

[0003] However, in the way of brain cell activation by drugs, there is a problem that only the desired specific site cannot be regulated by drugs

For electrical stimulation using a probe, the probe can be transplanted or inserted into a specific position of the brain by using electrocorticogram (Electrocorticogram) for brain surgery or deep brain stimulation (Deep brain stimulation: DBS), And perform electrical stimulation to temporarily or permanently change brain function, but with risks based on invasive methods

Also, the transcranial magnetic stimulation method is a non-invasive method for regulating brain function. It generates a strong magnetic field outside the cranium to cause an induced current to flow in the cerebral cortex, thereby regulating brain function. However, the above-mentioned transcranial magnetic stimulation As far as the magnetic stimulation device is concerned, the area of ​​the cerebral cortex stimulated by the non-invasive method is relatively wide (more than 2cm to 3cm), and it can only stimulate the surface of the brain cortex at a depth of 1cm to 2cm, while the magnetic field strength will be deeper in the brain. The area is drastically reduced, so there is a problem that fine adjustments cannot be made
