As shown in FIG. 1, the deep magnetic field generating coil 1 of the present embodiment includes a weir portion 11. The present invention does not limit the application range of the deep magnetic field generating coil 1, which can be applied, for example, to industrial heating applications or medical heating applications, and is applied to medical electromagnetic thermotherapy and can be used with An electromagnetic needle is used in conjunction with the application.

In this embodiment, the dam portion 11 can include a conductive element 111 and an insulating element In the case 112, the insulating member 112 is coated with the conductive member 111. The conductive element 111 is, for example, a tube body, a sheet-like body, or has other shapes, and the tube body is exemplified here. The material of the conductive element 111 is a magnetic conductive metal such as copper, an amorphous metal or other magnetically permeable material. The insulating member 112 is made of an insulating material such as, but not limited to, a plastic. Since the insulating member 112 is insulated, when the deep magnetic field generating coil 1 comes into contact with the patient, the patient does not have the risk of electric shock.

The crotch portion 11 has a height H1 (in meters), and the ratio of the number of the crotch portions 11 to the height is between 1 and 12,000. The definition of the height H1 is, for example, the distance from the highest point to the lowest point of one of the jaws 11. Here, the height H1 is, for example, 0.01 m, and the number of turns is one, so the ratio of the number of the crotch portions 11 to the height is 1/0.01=100.

The crotch portion 11 can have a space S. Here, the space of the crotch portion 11 is exemplified by the space inside the tube of the conductive element 111. The space S can accommodate a cooling liquid or a cooling gas. Thereby, the heat generated by the conductive member 111 can be effectively taken away. The above cooling liquid or gas system moves the tropics by circulation. The cooling liquid is, for example, water.

In addition, in the present embodiment, the inner diameter D of the crotch portion 11 is between 1 cm and 50. Between the centimeters, but this is by way of example only and is not intended to limit the invention. Further, one of the deep magnetic field generating coils 1 has a heatable depth DP of between 0 and 20 cm. The heatable depth DP can be calculated from the geometric center of the jaw 11 in a vertical direction (e.g., direction O as shown in Figure 2). The heatable depth DP represents, for example, that the temperature of the heated body can reach 50 ° C or higher under the conditions of this depth. Of course, the heatable depth DP can have other definitions, for example, defined as the magnetic flux density at the heatable depth DP being more than one fifth of the magnetic flux density at the center of the deep magnetic field generating coil 1.

The crotch portion 11 can be formed by a mold or a processing method in production. For example, a gel-like material is coated on the tubular conductive member 111, and the gel-like material is formed into the insulating member 112 by heat curing.

Then, the conductive element 111 is flattened by a processing method such that the crotch portion 11 has a height H1 (unit is a meter), and the ratio of the number of the crotch portion 11 to the height H1 is between 1 and 12000 (step S02) ). It should be noted that the order of steps S01 and S02 can be reversed. Here, the crotch portion 11 is first formed, and the conductive member 111 (i.e., the crotch portion 11) is crushed by a processing method (for example, by a pressurizing device). In other embodiments, the conductive element 111 may be first flattened by a processing method, and the insulating element 112 is then covered with the conductive element 111 to form the flange portion 11.

In addition, the manufacturing method of the deep magnetic field generating coil 1 further includes: introducing a cooling liquid or a cooling gas into a space S of one of the dam portions 11.

For example, a gel-like material is applied to the tubular conductive member 111, and the gel-like material is formed into the insulating member 112 by heat curing.

Then, the conductive element 111 is flattened by a processing method such that the crotch portion 11 has a height H2 (unit is a meter), and the ratio of the number of the crotch portion 11 to the height H2 is between 1 and 12000 (step S12) ). It should be noted that the order of steps S11 and S12 can be reversed. Here, the crotch portion 11 is first formed, and the conductive member 111 (i.e., the crotch portion 11) is crushed by a processing method (for example, by a pressurizing device). In other embodiments, the conductive element 111 may be first flattened by a processing method, and then the insulating element 112 is covered with the conductive element 111 to form a plurality of turns 11.

When the ratio of the height is limited to this range, the intensity of the deep magnetic field generated by it is greatly increased, so that the object to be heated to which the present invention is applied can be heated to a higher temperature under the same power supply. Therefore, the deep magnetic field generating coil of the present invention and the manufacturing method thereof can generate a high-intensity deep magnetic field, thereby improving the electromagnetic induction performance, thereby improving the treatment quality.
