Description

[0002] At present, transcranial magnetic stimulation technology has been widely used in clinical practice, and domestic transcranial magnetic stimulation technology has reached the world's advanced level.

[0003] The surface of the existing transcranial magnetic coil beater is made of hard material, and the shape of the shell that contacts the patient cannot be changed, resulting in poor stimulation effect. Especially when the magnetic coil beater is used to treat concave parts of the human body, it is difficult to fit these concave parts, such as the supraclavicular fossa of the human body, resulting in poor stimulation effect; secondly, the coil will generate a lot of heat during use. If this heat cannot be discharged in time, the temperature of the coil will increase, which will increase the resistance of the coil and reduce the magnetic field strength generated by the coil. At the same time, it will also accelerate the aging of the coil and shorten the service life of the coil.

[0004] In summary, there is an urgent need to design a transcranial magnetic coil beat that overcomes the above problems. Utility Model Content

[0036] See also Figures 1 to 4 , a transcranial magnetic coil shot, comprising:

[0037] A flexible insulating shell 1, a coil 2 arranged in the flexible insulating shell 1, a flexible cooling bag 3 arranged on one side of the flexible insulating shell 1, and a cooling liquid circulation drive device 4 connected to the flexible cooling bag 3; the flexible insulating shell 1, the coil 2 and the flexible cooling bag 3 constitute the parts in contact with the patient in the transcranial magnetic coil beat. During magnetic stimulation treatment, the device can deform according to the curve of the patient's body part and fit the patient's treatment part. It is not only suitable for magnetic stimulation treatment of the head, but also can be used for magnetic stimulation treatment of other parts of the patient under the guidance of a doctor according to needs. The flexible cooling bag 3 is adjacent to the coil 2. When the coil 2 is working, a large amount of heat will be generated. The flexible cooling bag 3 can take away the heat of the coil 2 and reduce its temperature; the flexible cooling bag 3 can be connected to one side of the flexible insulating shell 1 by hot melt glue or resin glue. The flexible insulating shell 1 can not only protect the coil 2 from leakage, but also play a role in fixing and installing the coil 2.

[0038] Specifically, the interior of the flexible cooling bag 3 is divided by a partition 31 to form a cooling liquid flow chamber 32, and the two ends of the cooling liquid flow chamber 32 are respectively connected to a liquid inlet pipe 33 and a liquid outlet pipe 34, and the other ends of the liquid inlet pipe 33 and the liquid outlet pipe 34 are respectively connected to the cooling liquid circulation drive device 4. The flexible cooling bag is divided by the partition 31 to form a cooling liquid flow chamber, and the two ports of the cooling liquid flow chamber are respectively connected to the liquid inlet pipe and the liquid outlet pipe, and the cooling liquid is circulated by the cooling liquid circulation drive device, so that the flowing cooling liquid takes away the heat generated by the magnetic stimulation coil to achieve the purpose of heat dissipation. The cooling liquid can be distilled water or deionized water.
