Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a miniaturized high-magnetic-flux powder core transcranial magnetic stimulation coil. Background Art

[0002] A transcranial magnetic stimulation coil is an internal component of a medical device used for non-invasive brain stimulation, which affects neuronal activity in specific areas of the brain by applying safe and adjustable magnetic field pulses near the surface of the scalp.

[0003] The existing transcranial magnetic stimulation coil is surrounded by an outer shell. When in use, the coil and the outer shell are placed on the acupuncture points of the brain, and then the device is turned on. The coil is activated through the connecting wire between them, so that the coil stimulates the acupuncture points. Since the connecting wire and the coil are integrated, if the connecting wire is damaged, the entire wire needs to be replaced, resulting in a waste of resources. Therefore, it is necessary to propose a stimulation coil that is easy to replace to avoid the need for replacing the entire coil. Utility Model Content

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] See also Figure 1-Figure 4 As shown, this embodiment is a miniaturized high-flux powder core transcranial magnetic stimulation coil, comprising:

[0034] The connecting blocks 21 are fixed to opposite ends of the coil body 11 , the insulating rods 22 are located between the inner ends of each set of connecting blocks 21 , and the connecting rods 25 are located inside the insulating rods 22 ;

[0035] The connecting block 21 is used for inserting and connecting the insulating rod 22, the insulating rod 22 is used for connecting the fixing rod 24, and the connecting rod 25 is used for inserting into the connecting block 21;

[0036] A fixing rod 24 is fixedly connected to the interior of the insulating rod 22, and an annular groove 23 is formed at the inner edges of both ends of the insulating rod 22;

[0037] The fixing rod 24 is used for connecting the connecting rod 25, the annular groove 23 is used for inserting the connecting block 21, and the insulating rod 22 is threadedly connected to the connecting block 21 through the annular groove 23;

[0038] The connecting rod 25 passes through and is fixed inside the fixing rod 24. The connecting block 21 is fixedly connected to the inside of the annular rod 26.

[0039] A docking groove 27 is provided inside the annular rod 26, and the docking groove 27 is plugged into the connecting rod 25, and the annular groove 23 is threadedly connected to the connecting block 21;

[0040] The annular rod 26 is used to fit with both ends of the fixed rod 24, and the docking groove 27 is used to insert the connecting rod 25. When the insulating rod 22 is rotatably connected to the connecting block 21, the insulating rod 22 drives the connecting rod 25 to gradually rotate and insert into the docking groove 27, so that the connecting rod 25 connects the coil bodies 11 on both sides through the docking groove 27, so that the coil bodies 11 on both sides are connected;

[0041] Working principle:

[0042] When in use, hold the insulating rod 22 by hand, pass both ends of the insulating rod 22 through the arc rod 32, so that the connecting rod 25 is inserted into the connecting block 21 at the opposite end of the coil body 11. At this time, the connecting block 21 is engaged with the annular groove 23. Then rotate the insulating rod 22 so that the insulating rod 22 is firmly connected to the connecting block 21 through the thread. At the same time, the insulating rod 22 drives the connecting rod 25 to gradually insert into the annular groove 23, so that the connecting rod 25 is connected to the coil body 11 through the port in the annular groove 23, so that the coil body 11 is activated through the connecting rod 25 to stimulate the acupuncture points of the brain.

[0043] In the above steps, the connecting rod 25 is replaced through the interaction between the insulating rod 22 and the connecting block 21 .

[0049] The insulating rod 22 is fixedly connected to the upper and lower sides with docking blocks 34, which are attracted by the magnetic block 33. The two ends of the insulating rod 22 pass through the arc rod 32.

[0050] The docking block 34 and the magnetic block 33 are attracted together, so that the two further limit the position of the insulating rod 22 after insertion;

[0051] Working principle:

[0052] When in use, the two ends of the insulating rod 22 are inserted into the upper and lower arc-shaped rods 32. During the insertion process, the docking block 34 and the magnetic block 33 are attracted to each other, and the connecting rod 25 is inserted into the docking groove 27. Thus, the attracted docking block 34 limits the inserted insulating rod 22 to prevent the insulating rod 22 from loosening after the threaded connection.
