Description

Technical Field

[0001] This utility model relates to the field of transcranial magnetic stimulation technology, specifically a transcranial magnetic stimulation helmet with its focus located in the frontal lobe. Background Technology

[0002] Transcranial magnetic stimulation (TMS) is a safe, painless, and non-invasive neuromodulation technique widely used in neuroscience research and clinical departments such as neurology, psychiatry, and rehabilitation. The principle of TMS is to generate a magnetic field through extracranial current, producing magnetic pulses that reach the cerebral cortex and induce currents. This current microscopically causes depolarization of local neurons and macroscopically alters neural activity, regulating cerebral blood flow and brain networks. However, most commercial coils are designed for general target sites, such as circular and figure-eight coils. These require complex operation and positioning, resulting in poor repeatability and a lack of coils specifically designed for localized target stimulation. Furthermore, existing helmets are often too large to fit various head shapes, causing them to wobble and affecting the stimulation effect when used by individuals with smaller heads.

[0003] Therefore, it is necessary to propose a transcranial magnetic stimulation helmet with the focus located in the frontal lobe to solve the above problems. Utility Model Content

[0004] Technical problem to be solved: The purpose of this utility model is to provide a transcranial magnetic stimulation helmet with the focus located in the frontal lobe, so as to solve the problems mentioned in the background art. Existing commercial coils are designed for general target sites, such as circular coils and figure-eight coils. When used, they require complicated operation and positioning, and the repeatability of positioning is poor. There is a lack of coils for special sites for magnetic stimulation of local targets. In addition, in order to adapt to various head shapes, the existing helmets are all too large. When people with small heads use them, the helmet is easy to shake, which affects the stimulation effect.

[0005] Technical solution: To achieve the above objectives, the present invention is implemented through the following technical solution: A transcranial magnetic stimulation helmet with a focal point located in the frontal lobe, comprising a helmet, and further comprising a first coil and a second coil connected in series, the first coil being wound around the bottom of the helmet at intervals, the second coil being wound around the top of the helmet at intervals, and the first coil and the second coil being converged on the right front side and / or left front side of the helmet to form a convergence part I and a convergence part II, the convergence part II being located in front of the convergence part I.

[0006] Preferably, the helmet shell has multiple annular grooves inside, and both the first coil and the second coil are disposed in the annular grooves.

[0007] Preferably, it also includes an adjustment device, which includes a front airbag, a rear airbag, a left airbag, a right airbag, and a top airbag fixedly installed on the inside of the helmet, and also includes a fixed cylinder with both ends sealed on the top of the outside of the helmet.

[0008] Preferably, the top of the front airbag, rear airbag, left airbag, right airbag, and top airbag is fixedly installed with the other end of a connecting tube, which is fixedly connected to a fixed cylinder. The fixed cylinder is connected to each airbag through the connecting tube, and the axis of the output end of the connecting tube on the front airbag, rear airbag, left airbag, and right airbag is located on the same horizontal plane.

[0009] Preferably, the outer ring of the rotating ring with the bottom opening is tightly in contact with the inner wall of the fixed cylinder, and four air outlets are evenly opened along the circumference on the outer ring of the rotating ring. The four air outlets correspond one-to-one with the output ends of the connecting pipes on the front airbag, rear airbag, left airbag, and right airbag, respectively. The top of the rotating ring is fixedly installed with a connecting rod that passes through the fixed cylinder and is fixedly installed with a knob.

[0010] Beneficial effects: Compared with the prior art, this utility model provides a transcranial magnetic stimulation helmet with the focus located in the frontal lobe. This transcranial magnetic stimulation helmet with the focus located in the frontal lobe has a unique structure and is easy to use. The device surrounds the first coil and the second coil around the bottom and top of the helmet, respectively, and converges them at the left anterior side, right anterior side and / or both sides of the frontal lobe to form convergence part I and convergence part II, and convergence part I and convergence part II overlap. Through the innovative design of double-layer wiring in the frontal lobe, the intensity and concentration of the induced electric field in the frontal lobe are enhanced. This layout allows the magnetic stimulation to act more accurately on the left frontal lobe, the right frontal lobe or both frontal lobe regions at the same time. At the same time, through the airbag adjustment mechanism, the helmet can adapt to different head shapes, solve the problem of helmet shaking, and improve the stability of stimulation and the accuracy of repeated positioning.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Example 1: This Example 1 provides a transcranial magnetic stimulation (TMS) helmet with the focus located in the frontal lobe. It is a direct improvement on existing TMS coils and has a unique structure. Please refer to [link / reference]. Figure 1-3 As shown, the device includes a helmet and a first coil 1 and a second coil 2 connected in series. The first coil 1 is wound around the bottom of the helmet at intervals, and the second coil 2 is wound around the top of the helmet at intervals. The first coil 1 and the second coil 2 converge on the right front side and / or left front side of the helmet to form a convergence part I3 and a convergence part II4. The convergence part II4 is located in front of the convergence part I3. There are three ways to arrange the first coil 1 and the second coil 2: the first is that the first coil 1 and the second coil 2 converge on the right front side of the helmet to form the convergence part I3 and the convergence part II4; the second is that the first... Coil 1 and coil 2 converge on the left front side of the helmet to form convergence part I3 and convergence part II4. In the third case, coil 1 and coil 2 converge on both the left front side and the right front side of the helmet to form convergence part I3 and convergence part II4. By using double-layer wiring at the focal position of the left, right and / or both frontal lobes, the number of ampere-turns is increased, thereby obtaining a stronger and more concentrated focal point of the induced electric field. There are various ways to install coil 1 and coil 2. For example, multiple annular grooves are opened inside the helmet shell, and coil 1 and coil 2 are both set in the annular grooves.

[0019] Example 2: The difference between Example 2 and Example 1 is as follows: Figure 4-5 As shown, it also includes an adjustment device, which includes a front airbag 5, a rear airbag 6, a left airbag 7, a right airbag 8, and a top airbag 9 fixedly installed on the inside of the helmet, and a fixing cylinder 11 fixedly installed on the top of the outside of the helmet. The two ends of the fixing cylinder 11 are sealed. The top of the front airbag 5, the rear airbag 6, the left airbag 7, the right airbag 8, and the top airbag 9 are all fixedly installed with connecting pipes 10. The other end of the connecting pipe 10 is fixedly connected to the fixing cylinder 11. The fixing cylinder 11 is connected to each airbag through the connecting pipe 10, and the axis of the output end of the connecting pipe 10 on the front airbag 5, the rear airbag 6, the left airbag 7, and the right airbag 8 is located on the same horizontal plane.

[0020] A rotating ring 12 with an open bottom is rotatably fitted inside the fixed cylinder 11. The outer ring surface of the rotating ring 12 is in close contact with the inner wall of the fixed cylinder 11, and four air outlets 13 are evenly opened along the circumference on the outer ring surface of the rotating ring 12. The four air outlets 13 correspond one-to-one with the output ends of the connecting pipes 10 on the front airbag 5, rear airbag 6, left airbag 7, and right airbag 8. In the initial state, the four air outlets 13 are interconnected with the connecting pipes 10 on the front airbag 5, rear airbag 6, left airbag 7, and right airbag 8, so that the airbags are connected together. A connecting rod 14 is fixedly installed on the top of the rotating ring 12. The top end of the connecting rod 14 passes through the fixed cylinder 11 and a knob 15 is fixedly installed thereon.

[0021] Working principle: When using this helmet, first select the appropriate helmet based on the desired stimulation location: the right frontal lobe, the left frontal lobe, or both frontal lobes simultaneously. Place the helmet on the patient's head and adjust its position so that the intersection of convergence points I3 and II4 is located at the desired frontal lobe. Additionally, the distance between the front of the helmet and the patient's forehead can be adjusted as needed, thereby adjusting the distance between the intersection of convergence points I3 and II4 and the forehead, and consequently, the intensity of the magnetic stimulation. (The text abruptly ends here.) When the helmet is in position, the gas in each airbag can enter the rotating ring 12 through the air outlet 13, so that the gas in each airbag can circulate with each other. After the helmet position is adjusted, turn the knob 15. The knob 15 drives the rotating ring 12 to rotate through the connecting rod 14 until the four air outlets 13 are all misaligned with the output end of the corresponding connecting tube 10. At this time, each airbag is in a closed state, and the position of the helmet is fixed. Through the coordinated arrangement of each airbag, the fixing cylinder 11 and the rotating ring 12, the helmet can be adapted to different head sizes.
