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

[0002] Transcranial magnetic stimulation technology is a magnetic stimulation technology that uses pulsed magnetic fields to act on the central nervous system (mainly the brain, including peripheral nerves and muscles). The magnetic signal can almost non-decayingly penetrate the skull to stimulate the cerebral cortex, change the membrane potential of cortical nerve cells, generate induced current, affect cerebral metabolism and nerve electrical activities, and thus cause a series of physiological and biochemical reactions.

[0003] In the existing transcranial magnetic stimulation generating device, as the number of treatment functions to be supported is increasing, the internal components required to support the functions also increase accordingly. However, the situation of messy stacking of components and the interlacing of each function module among them leads to chaotic wiring of the wires for electrical connection between the modules, uneven heat dissipation, and affects the performance release and working duration.

[0022] The following will make a detailed description of the specific embodiments of the present utility model with reference to the drawings.

[0023] As Figures 1 - 3As shown in the figure, the present utility model proposes a novel transcranial magnetic stimulation generating device, which includes a housing 100, a frame 200, a first component module 300, a second component module 400, a third component module 500, and a fourth component module 600. Radiators 101 are provided on both opposite sides of the housing 100. Among them, a main driving heat flow path 700 is formed between the two radiators 101 under their heat dissipation effect. The frame 200 is installed in the housing 100 and placed in the main driving heat flow path 700. The first component module 300 is installed on the frame 200, and the second component module 400 is installed in the frame 200. A secondary driving heat flow path 800 is provided in the frame 200 and arranged side by side with the second component module 400. The secondary driving heat flow path 800 has the same flow direction as the main driving heat flow path 700. The third component module 500 is installed in the housing 100 and placed on the side of the secondary driving heat flow path 800. The fourth component module 600 is installed in the housing 100. The first component module 300, the second component module 400, the third component module 500, and the fourth component module 600 are electrically connected to each other between two adjacent modules. Among them, the two radiators 101 dissipate the heat generated by the first component module 300 and the third component module 500 to the outside through the main driving heat flow path 700, and the two radiators 101 dissipate the heat generated by the second component module 400 and the third component module 500 to the outside through the secondary driving heat flow path 800.

[0024] In this embodiment, the novel transcranial magnetic stimulation generating device is electrically connected to an external stimulation coil device. The first component module 300 is a boost module, the second component module 400 is an energy supply module, the third component module 500 is a thyristor integrated module, and the fourth component module 600 is a high-voltage output module. Among them, the energy supply module is used for power input and power storage. The boost module is used for integrated processing of current signals. The boost module performs boost control processing on the electrical signals input by the power supply of the energy supply module and sends them to the power storage of the energy supply module to generate a high-voltage direct current. Then, the thyristor integrated module processes the high-voltage direct current into a high-voltage alternating current. Finally, the high-voltage output module processes the high-voltage alternating current and provides it to the external stimulation coil device, and the stimulation coil device processes the current into a magnetic field to provide magnetic stimulation to the user.

[0025] All modules of the novel transcranial magnetic stimulation generating device are located in the main driving heat flow path 700, so that the two radiators 101 can dissipate most of the heat generated by each module. Since each module is integrated in the small space of the housing 100, there are heat accumulation areas between each module. Therefore, by setting the frame 200 to separate each module, that is, dividing each module into regions, the secondary driving heat flow path 800 is arranged in the frame 200 and placed between the second component module 400 and the third component module 500, as shown in the appendix Figure 3As shown, a small part of the first component module 300 is also adjacent to the auxiliary drive hot runner 800. Therefore, through the auxiliary drive hot runner 800, the heat collection areas of the first component module 300, the second component module 400, and the third component module 500 are cooled to optimize the heat dissipation path and improve the heat dissipation effect.

[0026] Further, the radiator 101 is a cooling fan, and heat dissipation holes 102 are provided on both opposite sides of the housing 100, and the cooling fan is arranged at the heat dissipation holes 102.

[0027] Further, a heat dissipation block 301 is provided on the first component module 300, and the heat dissipation block 301 is a multi-fin aluminum block.

[0028] Specifically, the radiator 101 can be a liquid-cooled radiator. One radiator 101 is used as the input end of the cooling liquid, and the other radiator 101 is used as the output end of the cooling liquid. By injecting the cooling liquid, the heat generated by each module is taken away together. The liquid-cooling method has high requirements for the waterproof effect of the components and the sealing of the housing. Therefore, air-cooling is adopted in this embodiment.

[0029] Further, the third component module 500 includes a double-layer rack 501, a double-pass shell 502, a first unit 503, and two second units 504. The two second units 504 are respectively installed on the double-layer rack 501, and the first unit 503 is installed in the double-pass shell 502. The first unit 503 is electrically connected to the two second units 504 respectively.

[0030] Specifically, the first unit 503 is a thyristor for adjusting voltage, current, and power, and the second unit 504 is a protection component for absorbing overvoltage pulses. Since both of these two units can generate a large amount of heat, the double-layer rack 501 and the double-pass shell 502 are used as the installation carriers. Among them, the through direction of the double-pass shell 502 is the same as that of the main drive hot runner 700, so that the air duct of the main drive hot runner 700 can pass through the double-pass shell 502 to improve the heat dissipation efficiency of the first unit 503.

[0031] Further, both the housing 100 and the double-pass shell 502 are made of heat-conductive materials to further optimize the heat dissipation effect.

[0032] The above are one or more implementation manners provided in combination with specific contents, and it is not determined that the specific implementation of the present invention is only limited to these descriptions. All those that are similar or identical to the method, structure, etc. of the present invention, or those that make several technical deductions or substitutions under the premise of the concept of the present invention, should be regarded as the protection scope of the present invention.
