The invention is applied to a production device, in particular to a flexible depth magnetic field generating device.

Existing thermal treatments for tumors include microwave hyperthermia, radiofrequency ablation hyperthermia, and ultrasound focused hyperthermia. Among them, microwave hyperthermia and radiofrequency ablation hyperthermia are directly inserted into the needle electrode in the tumor; microwave thermotherapy uses the microwave radiator at the end of the microwave electrode to generate thermal effect, while radiofrequency ablation hyperthermia uses the RF current of the electrode needle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a flexible depth magnetic field generating apparatus according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings, wherein the same elements will be described with the same reference numerals.

FIG. 1 is a schematic diagram of a flexible depth magnetic field generating apparatus 1 according to an embodiment of the present invention. As shown in FIG. 1, the flexible depth magnetic field generating apparatus 1 of the present embodiment includes a strip-shaped flexible conductive member 11 and a strip-shaped flexible insulating member 12. The present invention does not limit the application range of the flexible depth magnetic field generating device 1, and can be applied, for example, to industrial heating applications or medical heating applications, and is applied to medical electromagnetic thermotherapy and Used in conjunction with an electromagnetic needle as an illustration.

The definition of "strip" of the strip-shaped flexible conductive member 11 can be, for example, an axial length of at least 10 times its radial length, whereby the flexibility can be improved. The material of the strip-shaped flexible conductive member 11 is a magnetic conductive metal such as copper, an amorphous metal or other magnetically permeable material. The strip-shaped flexible conductive member 11 may be made of a soft metal such as an amorphous metal. The strip-shaped flexible conductive member 11 can be made flexible by material properties or structural characteristics. In the present embodiment, the strip-shaped flexible conductive member 11 is formed by laminating a plurality of sheet-like metals 111, thereby achieving flexibility. The sheet metal 111 is, for example, a thin copper sheet. Further, as shown in Fig. 2, the strip-shaped flexible conductive member 11a may be composed of a spiral metal and thereby achieve flexibility. Further, as shown in FIG. 3, the strip-shaped flexible conductive member 11b may be constituted by a Litz wire, thereby achieving flexibility. Further, the strip-shaped flexible conductive member 11 may have other structures, for example, it may be configured as a flexible tube to achieve flexibility.

The strip-shaped flexible insulating member 12 covers the strip-shaped flexible conductive member 11 with a space S therebetween. The strip-shaped flexible insulating member 12 is made of an insulating material such as, but not limited to, a plastic. Since the strip-shaped flexible insulating member 12 is insulated, the patient does not have the risk of electric shock when it comes into contact with the patient. The length of the strip-shaped flexible insulating member 12 is matched with the strip-shaped flexible conductive member 11, for example, at least longer than the strip-shaped flexible conductive member 11. In the production, the strip-shaped flexible conductive element 11 can be directly placed into the strip-shaped flexible insulating element 12, and the two ends of the strip-shaped flexible conductive element 11 are connected with the strip-shaped flexible insulating element 12 to make two They are fixed to each other. Of course, the fixation of the above two can be achieved not only by the end but also by other parts. The fixing of the two can be fixed, for example, by locking, hot-melting, snapping, etc., or by means of additional fixing elements, such as a pressing element.

The space S can accommodate a cooling liquid or a cooling gas. Thereby, the heat generated by the strip-shaped flexible conductive member 11 can be effectively carried away. The above cooling liquid or gas system moves the tropics by circulation. The cooling liquid is, for example, water.

As shown in FIG. 4, the flexible depth magnetic field generating device 1 can surround the user's diseased part due to its flexibility, thereby greatly increasing the range of application. In application, the flexible depth magnetic field generating device 1 can be wound into a coil having at least one turn according to actual needs, and the second is taken as an example. The two ends of the flexible depth magnetic field generating device 1 are connected to the connection terminal E, and the connection terminal E can be connected to an AC power supply (not shown). Thus, the flexible depth magnetic field generating device 1 can generate a deep magnetic field, and the electromagnetic needle 2 can be heated according to the eddy current generated by the deep magnetic field, thereby burning off the tumor tissue and the like.

5A and 5B are schematic diagrams showing the depth magnetic field generated by the deep magnetic field generating device of the prior art and the flexible depth magnetic field generating device 1 of the present invention, respectively. As shown in FIG. 5A, since the conventional deep magnetic field generating device 3 can only be placed on the diseased site, the depth magnetic field generated by it is a vertical depth magnetic field having a depth H1 for a heating point P1, for example. As shown in FIG. 5B, since the flexible depth magnetic field generating device 1 of the present invention can surround the diseased portion, the depth magnetic field generated by the present invention is a planar depth magnetic field having a depth H2 for a heating point P2, for example. The second table is provided below to show how the strength of the deep magnetic field of the present invention and the effect of the resulting heating are superior to the prior art.

For example, a coil having a smaller diameter may be formed to surround the arm or neck, and a coil having a larger diameter may be formed to surround the chest or waist of the human body. In addition, in the above aspect, the flexible depth magnetic field generating device generates a planar deep magnetic field instead of the vertical deep magnetic field of the conventional technique, and the attenuation of the planar deep magnetic field is greatly reduced compared to the vertical deep magnetic field, so that the present invention The applied heat treatment needle can be heated to a higher temperature. In addition, the flexible depth magnetic field generating device of the present invention can be configured as coils of different numbers according to requirements to achieve different heating effects. fruit.
