Description

Coil Assembly for Transcranial Magnetic Stimulation Device and Transcranial Magnetic Stimulation Device thereof

The present invention relates to a transcranial stimulator, and more particularly, to a coil body of the transcranial stimulator and a transcranial stimulator suitable for increasing product processability, cooling efficiency, and easy attachment to a curved product.

In general, Transcranial Magnetic Stimulation (TMS) is a painless and non-invasive treatment method that stimulates neurons in the brain.

The conventional transcranial stimulator (TMS) has the following problems.

A typical transcranial stimulator uses a large Tesla-level power, so heat generation due to energy loss is very large.

In order to reduce the generation of such heat, a method was used to lower the internal resistance by forming a copper wire in the form of a copper tube and increasing the thickness of the copper tube.

However, even when the coil of the conventional transcranial stimulator is a copper tube, the copper tube is thick (eg, 6 to 10 mm thick) in order to generate Tesla-class electric power and to lower internal resistance.

However, when the thickness of the copper tube is increased in this way, the workability is remarkably lowered, so that the productivity of the product is lowered, and the processing cost is increased, thereby increasing the manufacturing cost of the product.

In addition, as the thickness of the product increases, the product has a problem in that the area occupied by the space is large.

In addition, it is very difficult to manufacture a coil applied to a curved product such as a helmet worn on the head, so there is a technical limit that cannot be applied to various products.

In particular, there was a problem that efficient cooling was impossible for products with space limitations.

In addition, since the thickness of the copper tube is thick, the weight is high, and the operator is uncomfortable during the operation.
