Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a magnetic stimulation coil device and a magnetic stimulation equipment. Background Technology

[0002] Magnetic stimulation (MS) technology, as a non-invasive neuromodulation technique, has made significant progress in the medical and health fields. Its applications are widespread, covering several important areas: transcranial magnetic stimulation (TMS) in the treatment of neurological and psychiatric diseases, musculoskeletal magnetic stimulation (MSS) in sports rehabilitation, and body-shaping magnetic stimulation (BMS) in aesthetic medicine. Based on the principle of electromagnetic induction, MMS applies high-frequency current pulses to a coil, generating a time-varying magnetic field around the coil. For example, TMS uses a time-varying magnetic field passing through the scalp and skull to stimulate specific areas of the brain, generating an induced electric field under the cerebral cortex. According to Faraday's law of electromagnetic induction, this induced electric field generates an induced current in neuronal tissue, thereby regulating neuronal activity. Similarly, musculoskeletal magnetic stimulation uses a time-varying magnetic field passing through the skin and soft tissue to generate an induced current in muscle tissue, causing changes in the membrane potential of muscle cells. Reaching a threshold triggers an action potential, which is transmitted along muscle fibers, triggering the release of calcium ions from the sarcoplasmic reticulum, causing muscle contraction. Body-shaping magnetic stimulation enhances muscle activity, increases metabolic activity, promotes fat breakdown and consumption, and improves muscle firmness by stimulating muscles and nerves, thereby improving body shape.

[0003] In magnetic stimulation devices, the coil is the core functional component that determines its therapeutic effect on the target area. When energized, the coil generates the magnetic field required for treatment. Magnetic stimulation therapy is typically a continuous process, during which the coil generates a significant amount of Joule heat. This heat affects the stability and lifespan of the coil's magnetic field output and poses a risk of burning the patient's skin at the treatment site, posing a safety threat. Therefore, a safe and effective cooling device is crucial for ensuring the effectiveness and smooth progress of magnetic stimulation therapy. Currently, domestic and international magnetic stimulation devices mainly employ air cooling or immersion liquid cooling technologies to address the heat generated by the coil during treatment. Air cooling primarily uses a fan to drive airflow, increasing the heat exchange efficiency between the coil and the surrounding air. Immersion liquid cooling utilizes the space between the coil and its outer casing to design a cavity for circulating cooling liquid, immersing the coil in the coolant, which circulates within the cavity to absorb and remove heat. However, existing technologies have the following drawbacks:

[0004] 1. Air-cooled coil cooling technology is noisy and its heat dissipation efficiency is limited by the thermal conductivity of air, making it difficult to meet the heat dissipation requirements of magnetic stimulation devices under high power output or long-term operation.

[0005] 2. Existing immersion cooling technology relies on the circulation of coolant in the cavity between the coil surface and the outer shell to remove heat. This poses a risk of coolant leakage, which may not only affect the normal operation of the equipment but also threaten the safety of patients and operators. Utility Model Content

[0046] Currently, magnetic stimulation devices both domestically and internationally primarily employ air-cooling or immersion liquid-cooling technologies to address the heat generated by the coils during treatment. Air-cooling mainly uses a fan to drive airflow, increasing the heat exchange efficiency between the coil and the surrounding air. Immersion liquid-cooling utilizes the space between the coil and its outer casing to design a cavity for circulating cooling liquid, immersing the coil in the coolant, which circulates within the cavity to absorb and remove heat. However, existing technologies have the following drawbacks:

[0047] 1. Air-cooled coil cooling technology requires perforations in the coil casing to create effective air convection. This design has significant shortcomings in terms of waterproofing and dustproofing, limiting the application environment of the equipment. Furthermore, to improve heat dissipation efficiency, the coil is often directly exposed to the air, but since the coil operates with high voltage, there is a potential risk of leakage, leading to reduced safety performance.

[0048] 2. Air-cooled technology relies on a fan to drive the airflow around the coil to dissipate heat. However, the fan generates a lot of noise during operation, which increases the patient's psychological discomfort during treatment and affects the treatment experience.

[0049] 3. The heat dissipation efficiency of air-cooled technology is limited by the thermal conductivity of air, making it difficult to meet the heat dissipation requirements of magnetic stimulation devices under high power output or long-term operation conditions.

[0050] 4. In order to achieve effective air cooling, a heat dissipation structure such as a fan must be integrated into the coil housing, which inevitably increases the overall size and reduces the portability and operational flexibility of the equipment.

[0051] 5. Existing immersion liquid cooling technology places high demands on the structural design of the coil housing, especially when adapting to coils with complex shapes. Complex structural designs not only increase manufacturing difficulty but also lead to higher manufacturing costs.

[0052] 6. Existing immersion cooling technology relies on the circulation of coolant in the cavity between the coil surface and the outer shell to remove heat. This poses a risk of coolant leakage, which may not only affect the normal operation of the equipment but also threaten the safety of patients and operators.

[0053] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0054] This embodiment provides a magnetic stimulation coil device and a magnetic stimulation equipment; please refer to... Figures 1-8 , Figure 1 This is a schematic diagram of the magnetic stimulation coil device provided in this embodiment; Figure 2 , Figure 4 and Figure 6 These are schematic diagrams of three structures for the coil body and cooling device provided in this embodiment, wherein...

[0055] The magnetic stimulation coil device provided in this embodiment relates to the field of medical device technology, specifically to the field of magnetic stimulation coil equipment technology. Addressing the shortcomings of existing magnetic stimulation coil cooling technologies, the magnetic stimulation coil device described in this embodiment provides a novel, efficient, safe, and adaptable cooling solution. This improves the performance stability and safety of magnetic stimulation equipment under high power output and long-term operation conditions, and also enhances the heat dissipation efficiency and environmental adaptability of the magnetic stimulation coil, thus optimizing the user experience. The magnetic stimulation coil device provided in this embodiment can be used in transcranial magnetic stimulation devices, musculoskeletal magnetic stimulation devices, orthopedic magnetic stimulation devices, etc.

[0056] See Figures 1-7 As shown, the magnetic stimulation coil device includes a housing 110, a coil body 120, a cooling device 130, and a colloid.

[0057] The coil body 120 and the cooling device 130 are respectively coiled and disposed inside the outer casing 110, and the coil body 120 and the cooling device 130 are stacked. For example, the coil body 120 and the cooling device 130 are stacked one on top of the other.

[0058] The colloid is a thermally conductive colloid and is filled inside the outer casing 110 by potting to cover the coil body 120 and the cooling device 130.

[0059] The cooling device 130 has a cooling channel inside, which extends along the extension direction of the cooling device 130 and is open at both ends so that the cooling medium can flow in the cooling channel.

[0060] Optionally, the cooling device 130 is made of insulating, high-temperature resistant, and thermally conductive material. Optionally, the tubing material of the cooling device 130 has excellent flexibility and plasticity, allowing for free bending at any angle, so that it can be precisely conformally arranged according to the specific geometry and size of the coil body 120.

[0061] The magnetic stimulation coil device described in this embodiment includes a housing 110, a coil body 120, a cooling device 130, and a colloid. The cooling device 130 has internal cooling channels that allow the cooling medium to flow within them. By encapsulating the coil body 120 and the cooling device 130 within the colloid, the heat generated on the coil body 120 can be dissipated through the coil body 120 and the colloid, via the cooling medium in the cooling channels. This effectively avoids or reduces cooling medium leakage and prevents short circuits between the cooling medium and the coil body 120, thus significantly improving the efficiency of cooling the coil body 120. The fanless design of the cooling device 130 and the encapsulating colloid eliminates the need for a fan to drive air for heat transfer, fundamentally eliminating the mechanical noise source of traditional air-cooling technology.

[0062] The magnetic stimulation coil device described in this embodiment improves and perfects the performance and efficiency limitations of commonly used coil cooling technologies, enabling the cooling device 130 to better serve the operation of the magnetic stimulation equipment. For example, the cooling device 130 does not require air to flow through the holes in the coil housing 110 to remove heat; instead, it adopts a completely sealed coil housing 110 structure design. This sealed structure effectively blocks the intrusion of moisture, dust, and other environmental media, allowing the magnetic stimulation equipment with the magnetic stimulation coil device to meet higher protection requirements. The sealed design significantly enhances the operational reliability of the magnetic stimulation equipment, enabling it to adapt to harsh working environments with high relative humidity or high concentrations of suspended particulate matter in the air. It effectively avoids the risk of coil insulation degradation, short circuits, and other faults caused by moisture or dust accumulation, reducing the maintenance frequency of the magnetic stimulation equipment and providing a reliable guarantee for the stable operation of the magnetic stimulation equipment in complex environments.

[0063] In an optional embodiment, at least one temperature sensor is connected to the surface of the coil body 120; the temperature sensor is encapsulated inside a colloid. The temperature sensor is used to monitor the surface temperature of the coil body 120 in real time.

[0064] In this embodiment, the optional encapsulant is an epoxy resin potting compound containing alumina. The epoxy resin potting compound has high insulation and high fluidity, allowing for complete impregnation and encapsulation of the coil body 120, forming a uniform insulating protective layer that constitutes the magnetic stimulation coil device, thus improving the reliability of the coil body 120 under high-voltage operating conditions. Simultaneously, thanks to the high mechanical strength properties of the epoxy resin potting compound, this coil encapsulation process not only ensures reliable fixation between the coil body 120 and the outer shell 110 but also significantly reduces noise caused by vibration during the output process. This design effectively improves the overall quietness of the magnetic stimulation device during operation, which is of significant value in optimizing the clinical treatment environment and helps improve the patient's treatment experience.

[0065] Compared to traditional liquid cooling technology, the magnetic stimulation coil device described in this embodiment employs indirect liquid cooling. A pipe made of high-insulation material serves as the cooling medium flow channel, completely isolated from the coil body 120, positioned on one side of the coil body 120. The cooling medium circulates in an independent channel between the coil body 120 and the outer shell 110, without direct contact with the coil body 120. This cooling device 130 abandons the integrated "coil-outer shell" cavity structure common in traditional liquid cooling technology. The outer shell 110 does not require a complex cooling cavity design, significantly simplifying the structural design of the coil outer shell 110 and reducing the complexity of mold development, processing steps, and manufacturing costs. The independent cooling channel design achieves complete isolation between the coolant and the coil body 120, greatly reducing the risk of leakage and eliminating the hidden danger of insulation failure due to coolant conductivity, further improving the insulation reliability of the cooling device 130.

[0066] Due to the high thermal conductivity of alumina, adding a certain proportion of alumina powder to a high thermal conductivity epoxy resin matrix can further improve the thermal conductivity of the matrix. Therefore, an experiment was conducted to investigate the ratio of matrix to alumina. The colloid consists of the matrix and alumina; the mass ratios of the matrix and alumina are shown in Table 1. The corresponding masses of matrix and alumina were thoroughly stirred in a container and then degassed in a vacuum pump for a certain time (e.g., 8 min). The mixture was then allowed to stand at room temperature for a period of time (e.g., 24 h) to cure. Temperature data was collected using a temperature sensor (e.g., a thermocouple) attached to the surface of the cured colloid. Colloids with different mass ratios were simultaneously immersed in a constant temperature water solution at a certain temperature (e.g., 60℃) for temperature rise testing, for example, for 8 min, with temperature data collected every 3 seconds. To visually compare the thermal conductivity of colloids with different mass ratios, the collected temperature data were plotted as curves on the same graph, as shown below. Figure 8 As shown.

[0067]

[0068] from Figure 8As can be seen, adding alumina to the adhesive accelerates the temperature rise. The best temperature rise is observed when the mass ratio of alumina to the adhesive is 0.15. However, adding alumina to the adhesive reduces its fluidity. Based on the functional differences between the coil body 120 and the cooling device 130, a selective encapsulation method is adopted. The pipeline carrying the coolant is the core component of the cooling device 130. Its potting process requires high thermal conductivity but relatively low fluidity. Therefore, impregnation encapsulation with a composite adhesive of alumina to the adhesive at a mass ratio of 0.15 is ideal. This method introduces epoxy resin composite material, whose thermal conductivity is tens of times that of air, as the heat transfer medium, constructing a more efficient heat conduction path, allowing the cooling medium to absorb more heat and improving cooling performance. Furthermore, a temperature sensor is integrated on the surface of the coil body 120 to continuously monitor its operating temperature through data acquisition.

[0069] In an optional embodiment, the mass ratio of alumina to the adhesive body is 0.15; wherein the mass of the adhesive body is the difference between the mass of the adhesive and the mass of alumina.

[0070] See Figures 2-7 As shown, in an optional embodiment, at least a portion of the coil body 120 and the cooling device 130 are tightly bonded together. This tight bonding helps improve the heat dissipation performance of the coil body 120. That is, in this embodiment, the coil body 120 and the cooling device 130 can be completely tightly bonded, or they can be partially bonded depending on the actual situation.

[0071] In an optional embodiment, the coil body 120 and the cooling device 130 can have the same or different winding shapes. See [link / reference] Figures 2-7As shown, in the optional embodiment, the coil body 120 and the cooling device 130 have the same winding shape; for example, the winding shape is circular, racetrack-shaped, or figure-eight-shaped. By having the coil body 120 and the cooling device 130 have the same winding shape, the tightness of the contact between their surfaces is improved. This design is not only simple to operate and requires less technical expertise from installers, but also reduces assembly time, saving labor costs and improving production efficiency. By using a circular, racetrack-shaped, or figure-eight-shaped winding shape, the length and arrangement density of the cooling device 130 can be flexibly adjusted according to the heat dissipation requirements of the coil body 120 at different power levels, providing good system adaptability. For high-power coil bodies 120, the tight winding of the cooling device 130 ensures that the cooling pipes for the cooling medium flow completely cover the surface of the coil body 120, maximizing the effective contact area between the cooling system and the heat source coil body 120. Furthermore, the thinner wall of the cooling device 130 reduces the heat transfer resistance from the coil body 120 to the cooling medium within the cooling device 130, improving cooling efficiency while ensuring safety. The cooling device 130 offers diverse specifications, allowing for optimized selection based on the medium flow rate corresponding to different inner diameters, the spatial constraints of the outer casing 110, and specific cooling requirements. This achieves the optimal configuration of the cooling device 130, selecting the smallest suitable size cooling device 130 piping within a limited space. This enables a compact spatial distribution of the cooling device 130 and the coil body 120 within the outer casing 110, effectively reducing the overall size of the magnetic stimulation coil device and providing technical support for lightweight design of magnetic stimulation equipment.

[0072] In an optional embodiment, the outer casing 110 has a casing notch.

[0073] The coil body 120 has an inlet end 121 and an outlet end 122; the inlet end 121 and the outlet end 122 are located at both ends of the extension direction of the coil body 120, and both the inlet end 121 and the outlet end 122 extend to the outside of the colloid and protrude from the shell notch.

[0074] The cooling device 130 has a cooling inlet 131 and a cooling outlet 132 that are connected to the cooling channel; the cooling inlet 131 and the cooling outlet 132 are located at both ends of the extending direction of the cooling device 130, and both the cooling inlet 131 and the cooling outlet 132 extend to the outside of the colloid and protrude from the shell notch.

[0075] Optionally, the cooling medium flowing within the cooling channel may include gas or liquid.

[0076] Optionally, the housing 110 includes a shell and a cover that fits over the shell; a shell notch is provided on the shell and / or the cover; the shell has a shell cavity that accommodates the coil body 120, the cooling device 130, and the colloid. Optionally, the shape of the shell cavity is adapted to the shape of the coil body 120; for example, the shape of the shell cavity is cylindrical, racetrack-shaped, or figure-eight shaped.

[0077] This embodiment also provides a magnetic stimulation device, including the magnetic stimulation coil device described in any of the above embodiments.

[0078] Optionally, the magnetic stimulation device may be a transcranial magnetic stimulation device, a musculoskeletal magnetic stimulation device, or a shaping magnetic stimulation device, or other devices.

[0079] The magnetic stimulation device provided in this embodiment includes the aforementioned magnetic stimulation coil device. The technical features of the disclosed magnetic stimulation coil device are also applicable to this magnetic stimulation device, and the technical features of the disclosed magnetic stimulation coil device will not be described again. The magnetic stimulation device in this embodiment has the advantages of the aforementioned magnetic stimulation coil device, and the advantages of the disclosed magnetic stimulation coil device will not be described again here.

[0080] To better understand the magnetic stimulation coil device and magnetic stimulation equipment described in this embodiment, their control methods are briefly described below, for example:

[0081] The temperature of the coil body 120 is obtained, for example, by means of a temperature sensor.

[0082] When the temperature is within the first temperature range, the refrigerator operates in a low-speed mode; the cooling channel of the magnetic stimulation coil device is connected to the refrigerator, which is used to deliver the cooling medium to the cooling channel.

[0083] When the temperature falls within the second temperature range, the refrigeration unit operates in the medium-range mode.

[0084] When the temperature falls within the third temperature range, the refrigeration unit operates in high-speed mode.

[0085] When the temperature falls within the fourth temperature range, the refrigerator operates in ultra-high operating mode and the magnetic stimulation device stops outputting to ensure the safety of the magnetic stimulation device.

[0086] Optionally, the first temperature range is less than 30°C, the second temperature range is greater than or equal to 30°C and less than 35°C, the third temperature range is greater than or equal to 35°C and less than 41°C, and the fourth temperature range is greater than or equal to 41°C.

[0087] For example, the temperature of the cooling medium is regulated by a chiller with four-level adjustment capabilities. By establishing a dynamic response relationship between the temperature of the coil body 120 and the cooling power, the magnetic stimulation device achieves adaptive adjustment: when the temperature sensor indicates that the operating temperature of the coil body 120 is below 30°C, the chiller operates in low-speed mode; when the operating temperature of the coil body 120 is in the 30-35°C range, the chiller switches to medium-speed operation; when the operating temperature of the coil body 120 rises to the 35-40°C range, the chiller upgrades to high-speed operation; when the operating temperature of the coil body 120 continues to climb above the 41°C threshold, the chiller activates ultra-high-speed cooling mode and the magnetic stimulation device stops outputting power to ensure the safety of the device. This temperature feedback device, by matching the heat of the coil body 120 with the power output of the chiller, regulates the temperature of the coolant to the optimal range, not only regulating the temperature stability of the coil body 120 but also reducing system energy consumption and avoiding unnecessary energy waste.

[0088] In this embodiment, the cooling device 130 enables the cooling medium to circulate in an independent cooling channel. Combined with a temperature sensor and a highly thermally conductive colloid, heat generated on the coil body 120 is conducted through the "coil body 120—colloid—cooling medium in the cooling device 130" pathway. The temperature sensor monitors the operating temperature of the coil body 120 in real time, and the temperature of the circulating cooling medium in the cooling device 130 is precisely controlled based on the feedback temperature data. The cooling channel of the cooling device 130 is constructed of a highly insulating, high-temperature resistant, and thermally conductive material, preventing short circuits between it and the energized coil body 120, and avoiding damage from the heat generated on the coil body 120. This ensures that there are no safety issues when the cooling device 130 is in close contact with the coil body 120.

[0089] The magnetic stimulation coil device and magnetic stimulation equipment described in this embodiment have high insulation, high safety, simple and compact structural design, low space occupation, low cost, variable shape and independent cooling channel with high efficiency cooling performance.

[0090] The magnetic stimulation coil device and magnetic stimulation equipment described in this embodiment employ a fully sealed outer shell 110 design to isolate the intrusion of water vapor or dust, thereby enhancing the safety and reliability of the equipment. Emphasis is placed on reducing equipment noise, employing a fanless design and using an impregnation encapsulation method for the coil body 120 to reduce noise generation. An independent cooling channel reduces the possibility of cooling medium leakage onto the coil body 120 during flow, lowering the frequency of equipment maintenance. Simultaneously, this cooling channel allows for a more compact structure of the cooling device 130, improving the portability and flexibility of the equipment. Because the piping of the cooling device 130 has high plasticity, it can adapt to various complex shapes of the coil body 120, increasing the degree of heat absorption by the cooling device 130. Different functional modules can be encapsulated using the most suitable thermally conductive medium, improving insulation while enhancing heat conduction efficiency.

[0091] The magnetic stimulation coil device and magnetic stimulation equipment described in this embodiment have the following advantages:

[0092] 1.
