Technical Field

[0002] Transcranial magnetic stimulation technology (TMS) is a non-invasive neuroregulation technology that uses an electromagnetic coil to generate a pulsed magnetic field, which acts on the central nervous system of the brain, changes the membrane potential of cortical neurons in the brain, generates an induced current, affects cerebral metabolism and nerve electrical activities, and thus causes a series of physiological and biochemical reactions of magnetic stimulation technology. This technology is used to treat mental diseases such as depression, anxiety, and schizophrenia, as well as neurological diseases such as Parkinson's disease and epilepsy. At the same time, transcranial magnetic stimulation technology is also widely used to study the mechanisms of brain function and neurological diseases.

[0003] The transcranial magnetic stimulation coil is a key device for transcranial magnetic stimulation. It usually consists of a multi-turn coil wound in a disc shape. This coil is placed on the patient's head and generates a time-varying induced magnetic field by passing an electric current pulse. The magnetic field penetrates the scalp and skull and directly stimulates the neurons in the cerebral cortex. The transcranial magnetic stimulation coil regulates the excitability of brain neurons by changing the magnetic field, thereby producing a series of neuroregulation effects.

[0004] Currently, professional doctors or positioning instruments such as robotic arms are still required to assist during the treatment of TMS coils, which increases the number of treatment devices and makes it quite difficult for non-professional personnel to perform TMS treatment at home.

[0026] The following will describe the specific embodiments of the present utility model in detail with reference to the drawings.

[0027] Such as Figures 1-6As shown, the utility model proposes a fixing device for a transcranial magnetic stimulation coil, which is applied to a headgear 100. The headgear 100 includes an inner layer 101 and an outer layer 102. The headgear 100 is provided with a through hole 103 connecting the inner layer 101 and the outer layer 102. The fixing device for the transcranial magnetic stimulation coil includes a stimulation coil body 200 and an assembly component 300. The stimulation coil body 200 is provided with a plurality of disassembly components 201. The assembly component 300 is provided with a plurality of mounting parts 301 which correspond to the plurality of disassembly components 201 one by one and can be detachably connected. The assembly component 300 has a certain deformation ability, and the connection between the disassembly component 201 and the mounting part 301 is unlocked according to the change of the deformation state of the assembly component 300.

[0028] The specific implementation method is: the assembly component 300 is applied to the inner layer 101 of the head cover 100 and placed at the through hole 103, and the stimulation coil body 200 is detachably installed from the outer layer 102 of the head cover 100 and the assembly component 300 to clamp the head cover 100 therein, wherein the deformation ability of the assembly component 300 is utilized to change the deformation state of the assembly component 300 to unlock the connection between the disassembly component 201 and the installation part 301, thereby realizing rapid disassembly and assembly, and facilitating user operation.

[0029] Furthermore, the mounting portion 301 includes a first groove 3011 and a second groove 3012 that are connected to each other, and the first groove 3011 is connected to one side of the assembly component 300, wherein the disassembly component 201 penetrates into the first groove 3011 and moves into the second groove 3012 to complete the installation of the assembly component 300 and the stimulation coil body 200.

[0030] A limiting protrusion 3013 is provided in the second groove 3012. When the disassembly component 201 enters the second groove 3012, the limiting protrusion 3013 is used to contact the disassembly component 201 and limit its movement.

[0031] See attached Figure 6 , the limiting protrusion 3013 is specifically a block protruding from the inner wall of the second groove 3012, and the structure of the limiting protrusion 3013 is a gentle slope on one side and a right-angle slope on the other side, and one side of the gentle slope faces the first groove 3011. When the disassembly component 201 enters the second groove 3012 and continuously moves deeper into the second groove 3012, it will first collide with the gentle slope. Since the gentle slope continuously raises the collision height, the deformation ability of the assembly component 300 itself affects the disassembly component 201, so that the disassembly component 201 can continue to go deeper. Until the deep part of the second groove 3012, the disassembly component 201 is restricted by the right-angle slope to complete the installation of the assembly component 300 and the stimulation coil body 200. When disassembling, the deformation state of the assembly component 300 is changed, so that the disassembly component 201 can break away from the restriction of the right-angle slope and return to the first groove 3011.

[0032] Furthermore, the disassembly component 201 includes a protrusion, the size of which is adapted to the width of the first groove 3011 and the second groove 3012.

[0033] Furthermore, chamfers are provided on both sides of the protrusion, and the chamfer amplitude on the first side of the protrusion is smaller than the chamfer amplitude on the second side of the protrusion, wherein, when the disassembly component 201 enters the second groove 3012, the limiting protrusion 3013 is used to abut against the first side of the protrusion.

[0034] Specifically, the chamfering facilitates the movement of the protrusion against the limiting protrusion 3013. The second side of the protrusion is to contact the right-angle slope, and when performing the disassembly work, the protrusion needs to be separated from the depth of the second groove 3012. When changing the deformation state of the assembly component 300, the protrusion may smoothly cross the right-angle slope and enter the first groove 3011. At the same time, there is also a possibility that the protrusion is stuck by the right-angle slope, so a chamfer design is required to avoid the situation of being stuck. The reason why the chamfer amplitude on the first side of the protrusion is smaller than the chamfer amplitude on the second side of the protrusion is to ensure that the protrusion stays stably in the depth of the second groove 3012 while ensuring that the above-mentioned stuck situation is not easy to occur.

[0035] Furthermore, the assembly component 300 includes an annular block, on which a notch 302 is provided, wherein the annular block can undergo contraction deformation or expansion deformation in a direction toward the notch 302 or away from the notch 302.

[0036] Furthermore, a plurality of holes 303 are provided on the annular block.

[0037] Specifically, in order to prevent the assembly component 300 and the stimulation coil body 200 from shifting when clamped on the headgear 100, a plurality of holes 303 are provided on the annular block, and these holes 303 are sewing holes. The annular block is sewn to the inner layer 101 of the headgear 100 and placed at the through hole 103 through the sewing holes. Of course, other fixing methods can also be used, such as sticking Velcro on the annular block, and setting a barb sticker corresponding to the Velcro on the inner layer 101. The annular block is attached to the barb sticker through the Velcro to achieve a fixed installation effect.

[0038] The above is one or more implementation methods provided in combination with specific content, and it is not considered that the specific implementation of the utility model is limited to these descriptions. Any method, structure, etc. similar to or identical to the method, structure, etc. of the utility model, or any technical deduction or replacement based on the concept of the utility model, shall be regarded as the protection scope of the utility model.
