Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a novel transcranial magnetic stimulation coil. Background Art

[0002] Transcranial magnetic stimulation technology is a magnetic stimulation technology that uses a time-varying pulsed magnetic field to act on the central nervous system (mainly the brain), changes the membrane potential of cortical nerve cells, generates an induced current, affects cerebral metabolism and nerve electrical activities, and thus causes a series of physiological and biochemical reactions. Different modes of repetitive transcranial magnetic stimulation can change neural structure, affect brain nerve function and nerve regulation in addition to causing a series of physiological and biochemical reactions.

[0003] The existing transcranial magnetic stimulation coil is planar. When working, since the human head is round, when the coil is placed on the head for magnetic stimulation, the two ends of the coil are far from the head, resulting in a weak magnetic field intensity at the two ends of the coil. Therefore, the magnetic stimulation area received by the head during a single magnetic stimulation process is relatively small, and the magnetic stimulation effect is not good. Moreover, since the single-channel coil has only a single current input, effective coupling cannot be formed between various parts of the coil. Summary of the Utility Model

[0025] The following will make a detailed description of the specific embodiments of the present utility model with reference to the drawings.

[0026] As Figures 1-4 shown, the present utility model provides a novel transcranial magnetic stimulation coil, which includes a housing 100, a coil disk group 200, a wire splitter 300, and a plurality of units 400. The coil disk group 200 is installed inside the housing 100. The coil disk group 200 includes a first part 201 and a second part 202 that are symmetrically arranged with each other. The first part 201 includes at least two first coils 2011 arranged side by side, and the second part 202 includes at least two second coils 2021 arranged side by side. There is a first included angle between the first coil 2011 and the second coil 2021. The plurality of units 400 are respectively connected to the inside of the housing 100 through the wire splitter 300 and are respectively electrically connected to the corresponding first coil 2011 and second coil 2021. The unit 400 is used to provide electrical pulses to the corresponding first coil 2011 or second coil 2021.

[0027] Specifically, the novel transcranial magnetic stimulation coil in this embodiment is connected to an external host. The host is electrically connected to multiple units 400. The host controls the electrical pulse output and output direction of the multiple units 400. The host adjusts the electrical pulse output of the multiple units 400 to achieve the conversion of the coil from a single channel to multiple channels, and adjusts the electrical pulse output magnitude and output direction to achieve magnetic field coupling between the coils, thereby changing the magnetic field distribution in the stimulation area.

[0028] Further, the first coil 2011 is a coil wound by a metal wire according to a specified pattern, and the pattern includes a polygon or a circle.

[0029] Refer to the appendix Figure 3 In this embodiment, the first coil 2011 and the second coil 2021 have the same structure and are both wound into square coils. Among them, the first part 201 is two first coils 2011 arranged side by side, and the second part 202 is two second coils 2021 arranged side by side. There is a certain first angle between the first part 201 and the second part 202. Since it is used for transcranial magnetic stimulation of the user, this angle position is used to adapt to the user's skull position and increase the magnetic stimulation area received by the skull. The setting of the angle can also deepen the magnetic field depth and improve the magnetic stimulation effect. According to different configurations or requirements, the angle range of the first angle is 100°-180°.

[0030] Further, the metal wire is a purple copper wire with an insulating layer.

[0031] In another embodiment, there is a second angle between multiple first coils 2011, and there is a second angle between multiple second coils 2021. The angle range of the second angle is 100°-180°.

[0032] Specifically, for different configurations and user requirements, the shape of the coil can also be set to different patterns accordingly. As shown in the appendix Figure 4 The first coil 2011 and the second coil 2021 both adopt triangular patterns and are at a certain angle to each other.

[0033] Further, the unit 400 includes a cable 401, a connector 402, and a display screen 403. The connector 402 is electrically connected to the splitter 300 through the cable 401, and the display screen 403 is installed on the connector 402. The cable 401 is provided with a power line and a signal line.

[0034] Specifically, the structures such as the housing 100, the wire splitter 300, the cable 401, and the connector 402 are all made of fireproof, waterproof, and heat-insulating plastic materials to meet the requirements of the shell strength and fire rating. The display screen 403 is signal-connected to the signal line and is used to collect data information such as temperature and signal of the first coil 2011 or the second coil 2021, and will display the specific values. Moreover, it also has a function of over-temperature alarm.
