Description

Technical Field

[0001] This invention relates to the field of fascia therapy technology, specifically to a high-pressure contact-type cool microwave deep fascia therapy device. Background Technology

[0002] In the field of physical therapy, effective treatment of deep fascia tissue (typically >3cm in depth) has always been a challenge. Existing equipment for soft tissue treatment mainly falls into two categories: traditional microwave therapy devices and radiofrequency ablation devices. However, both types of equipment have significant technical limitations, making it difficult to meet the clinical needs of deep fascia treatment. Specifically:

[0003] Traditional microwave therapy devices have a maximum power of ≤100W and a penetration depth of <1.5cm, with an energy density of only 5mW / cm² in the deep fascia region. 3 The maximum power of the radiofrequency hyperthermia device is 200W, and although the penetration depth has been increased to 2-3cm, the deep fascia energy density is still only 20mW / cm. 3 Microwave energy below 100W cannot penetrate dense connective tissue (such as deep fascia) with a water content of <30%. The energy will be completely absorbed by superficial tissue with high water content, resulting in a lack of deep treatment effect and easily causing overheating damage to superficial tissue.

[0004] To achieve effective treatment of deep fascia tissue, clinicians have specific requirements for the equipment: maximum power must reach 350W, and penetration depth must be [specific value missing].

[0005] ≥3cm, deep fascia energy density needs to be ≥50mW / cm 3 However, existing equipment is limited by design flaws in voltage, power, and frequency coordination, as well as insufficient thermal management technology, and cannot simultaneously meet the above parameter requirements: on the one hand, increasing power to increase penetration depth will lead to excessive temperature rise in shallow tissues (epidermal temperature > 45°C under the same power of traditional equipment); on the other hand, the waveguide structure of traditional equipment has serious energy scattering problems, with reflection loss > 35%, which further reduces the efficiency of deep energy transfer.

[0006] Therefore, developing deep fascia therapy equipment with high-voltage field strength compensation, precise frequency control, and efficient thermal management has become an urgent problem to be solved. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a high-voltage contact-type cooling microwave deep fascia therapy device, so as to achieve high-voltage precise and stable output, improve microwave energy focusing efficiency, enhance the cooling effect of the device, ensure the insulation safety of the device, and thus improve the effectiveness and safety of deep fascia therapy.

[0008] To solve the above-mentioned technical problems, the technical solution provided by the present invention is: a high-voltage contact-type cooling microwave deep fascia therapy device, comprising a shell, a touch screen, a high-voltage generator, a magnetron, a cooling system, a power module, a control unit, and a waveguide focusing head;

[0009] The power module is connected to the control unit, the control unit is connected to the cooling system and the high-voltage generator, and the high-voltage generator is connected to the magnetron;

[0010] The touch screen is fixed to the top of the housing, and a switch is also provided on the top of the housing. One end of the waveguide focusing head is connected to the magnetron via a connecting wire.

[0011] The high-voltage generator produces 1850-1950V high voltage;

[0012] The waveguide focusing head uses a contact-type insulated head.

[0013] Furthermore, the waveguide focusing head consists of, from the inside out, a copper waveguide cavity, a microchannel cooling layer, a PTFE insulating contact surface, and a boron nitride gradient insulating layer.

[0014] Furthermore, the inner layer of the boron nitride gradient insulating layer is a high-dielectric region with a dielectric constant ε. 内 =4.2; the outer layer of the boron nitride gradient insulating layer is a low dielectric region with a dielectric constant ε. 外 =3.8.

[0015] Furthermore, the water cooling fluid flow rate within the microchannel cooling layer is 6 L / min.

[0016] Furthermore, the cooling system includes a liquid cooling unit, an air cooling unit, and cooling plates. The liquid cooling unit includes a water pump, a water tank, and a radiator. The water pump is connected to the water tank and the radiator via water pipes, which are arranged on the devices that require heat dissipation. The air cooling unit uses a cooling fan. Both the liquid cooling unit and the air cooling unit are connected to cooling plates, which are connected to the waveguide focusing head.

[0017] Furthermore, the magnetron has a peak power of 350W and an operating frequency of 40.68GHz.

[0018] Furthermore, the bottom of the housing is equipped with casters.

[0019] The advantages of this invention compared to existing technologies are as follows: The high-voltage contact-type cooling microwave deep fascia therapy device of this invention achieves a stable output of 1850-1950V high voltage through optimized high-voltage generator design, providing the optimal operating voltage for the magnetron and ensuring that the magnetron can stably generate microwave energy with a peak power of 350W and an operating frequency of 40.68GHz. This microwave energy has strong penetrating power and good tissue selectivity, enabling it to precisely act on the patient's deep fascia tissue, effectively improving blood circulation in the deep fascia, promoting the absorption of inflammatory factors, relieving muscle spasms, and loosening fascial adhesions. This rapidly relieves the patient's pain symptoms and restores joint mobility, resulting in a significantly better therapeutic effect than existing similar devices. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0030] The following is a detailed description of the high-pressure contact cooling microwave deep fascia therapy device of the present invention, with reference to the accompanying drawings.

[0031] Combined with appendix Figure 1-7 This invention will be described in detail below.

[0032] A high-voltage contact-type cooling microwave deep fascia therapy device includes a housing 1, a touch screen 2, a high-voltage generator 3, a magnetron 4, a cooling system, a power module 5, a control unit 6, and a waveguide focusing head 7.

[0033] The power module 5 is connected to the control unit 6 and is used to provide a stable power supply to the control unit 6, ensuring that the control unit 6 can operate normally and effectively control the various modules of the equipment.

[0034] The control unit 6 is connected to the cooling system and the high-voltage generator 3 respectively. The control unit 6 can send control signals to the cooling system according to the working status and preset parameters of the equipment to adjust the working mode and intensity of the cooling system. At the same time, the control unit 6 can also control the operation of the high-voltage generator 3 to achieve precise regulation of high-voltage output.

[0035] The high voltage generator 3 is connected to the magnetron 4. Under the control of the control unit 6, the high voltage generator 3 generates high voltage and transmits it to the magnetron 4, providing the necessary high voltage conditions for the operation of the magnetron 4.

[0036] One end of the waveguide focusing head 7 is connected to the magnetron 4 via a connecting line. The microwave energy generated by the magnetron 4 is transmitted to the waveguide focusing head 7 via the connecting line. After being focused by the waveguide focusing head 7, it acts on the patient's deep fascia tissue to achieve the therapeutic purpose.

[0037] As the external protective structure of the equipment, the outer casing 1 not only protects the internal electrical components and prevents external factors from damaging them, but also provides a stable operating platform for the operators.

[0038] The touch screen 2 is fixed to the top of the outer casing 1. The touch screen 2 adopts a high-definition display panel, which has good touch sensitivity and anti-interference ability. Operators can set the treatment parameters of the equipment (such as treatment time, microwave power, etc.) and view the working status of the equipment (such as high voltage output value, cooling system working status, etc.) through the touch screen 2. The operation is convenient and intuitive.

[0039] The top of the housing 1 is also equipped with a switch 8, which is used to control the overall power on and off of the equipment, providing a convenient control method for starting and stopping the equipment.

[0040] To facilitate the movement and position adjustment of the equipment, the bottom of the housing 1 is equipped with a caster wheel 18. The caster wheel 18 is made of wear-resistant and non-slip material and has a braking function. When the equipment is moved to the designated position, the caster wheel 18 can be locked by the braking device to prevent the equipment from sliding during operation.

[0041] The high-voltage generator 3 is the core component of the equipment that generates high voltage. Under the control of the control unit 6, it can stably output a high voltage of 1850-1950V. This high voltage range has been verified through extensive experiments and can provide the optimal operating voltage for the magnetron 4, ensuring that the microwave energy generated by the magnetron 4 is stable and meets the needs of deep fascia therapy. This effectively avoids problems such as reduced treatment effect or equipment damage caused by excessively high or low voltage.

[0042] The magnetron 4 is a key component in the device that generates microwave energy, with a peak power of 350W and an operating frequency of 40.68GHz. The selection of this peak power and operating frequency fully considers the characteristics of deep fascia tissue. The 350W peak power ensures sufficient penetration of the microwave energy, effectively targeting deep fascia tissue to treat problems such as inflammation and adhesions. The 40.68GHz operating frequency is a specific frequency within the microwave band, exhibiting excellent transmission characteristics in human tissue with minimal energy loss, allowing for precise targeting of the treatment area and minimizing damage to surrounding healthy tissue.

[0043] The waveguide focusing head 7 adopts a contact-type insulated head design. The contact design allows microwave energy to be applied directly to the patient's treatment site, minimizing microwave energy loss during transmission and improving energy utilization. The insulated head design effectively prevents leakage under high-voltage operating conditions, ensuring the safety of patients and operators.

[0044] Structurally, the waveguide focusing head 7 consists of, from the inside out, a copper waveguide cavity 9, a microchannel cooling layer 10, a PTFE insulating contact surface 11, and a boron nitride gradient insulating layer 12.

[0045] The copper waveguide cavity 9 has excellent microwave conduction performance, which can efficiently transmit the microwave energy transmitted from the magnetron 4 to the treatment area and play a preliminary focusing role in the microwave energy to ensure the directionality and concentration of the microwave energy.

[0046] The microfluidic cooling layer 10 is located outside the copper waveguide cavity 9, and a coolant flows through it at a rate of 6 L / min. During operation, the waveguide focusing head 7 generates heat due to the transmission and conversion of microwave energy. The coolant in the microfluidic cooling layer 10 flows rapidly at a rate of 6 L / min, which can promptly remove the heat generated by the waveguide focusing head 7, keeping it at a suitable operating temperature. This prevents excessive temperature from affecting the transmission and focusing effect of microwave energy, and also prevents burns to the patient's skin caused by high temperatures.

[0047] The PTFE insulating contact surface 11 has excellent insulation properties and biocompatibility. It comes into direct contact with the patient's skin, which not only further enhances the insulation safety of the equipment, but also reduces irritation to the patient's skin and improves the patient's comfort during treatment.

[0048] The boron nitride gradient insulating layer 12 is located on the outermost layer of the waveguide focusing head 7. Its inner layer is a high-dielectric region with a dielectric constant εinner = 4.2, while the outer layer is a low-dielectric region with a dielectric constant εouter = 3.8. This gradient dielectric constant design effectively optimizes microwave energy transmission and focusing. The high-dielectric region promotes microwave energy concentration, while the low-dielectric region reduces microwave energy reflection loss on the surface of the waveguide focusing head 7, allowing more microwave energy to act on the treatment area and improving the treatment effect. Simultaneously, the boron nitride material itself has excellent insulation and high-temperature resistance properties, further enhancing the insulation safety and high-temperature resistance of the waveguide focusing head 7, ensuring the stability and safety of the equipment under long-term high-voltage operation.

[0049] The cooling system includes a liquid cooling unit, an air cooling unit, and cooling fins 16. The cooling system adopts a composite cooling method that combines liquid cooling and air cooling, which can achieve efficient heat dissipation of various heat-generating components of the equipment and ensure that the equipment maintains a stable working state during long-term operation.

[0050] The liquid cooling unit includes a water pump 13, a water tank 14, and a radiator 15. The water pump 13 connects the water tank 14 and the radiator 15 via water pipes, which are arranged on the components requiring heat dissipation (such as the high-voltage generator 3 and the magnetron 4). When the liquid cooling unit is working, the water pump 13 draws coolant from the water tank 14. The coolant flows through the water pipes to each heat-generating component, absorbing the heat generated by the component, and then flows to the radiator 15. The radiator 15 dissipates the heat from the coolant into the air. The cooled coolant then flows back to the water tank 14, forming a circulation of coolant to achieve continuous heat dissipation from the heat-generating components.

[0051] The air-cooled unit uses a cooling fan 17, which is installed in a suitable position on the equipment casing 1. It can accelerate the airflow inside the equipment, exhaust the hot air inside the equipment, and at the same time draw in the cold air from the outside, forming good air convection, assisting the liquid cooling unit in heat dissipation, and further improving the heat dissipation efficiency of the equipment.

[0052] Both the liquid cooling unit and the air cooling unit are connected to the cooling plate 16, which is connected to the waveguide focusing head 7. The cooling plate 16 is made of a material with high thermal conductivity, which can quickly conduct the heat generated by the waveguide focusing head 7 to the liquid cooling unit and the air cooling unit, and then dissipate the heat through the liquid cooling unit and the air cooling unit, ensuring that the temperature of the waveguide focusing head 7 is effectively controlled.

[0053] Control unit 6 is the core control component of the equipment, employing a high-performance microprocessor with powerful data processing and control capabilities. Control unit 6 can receive operation commands sent from touchscreen 2 and, according to preset programs and algorithms, monitor and control the operating status of components such as high-voltage generator 3, cooling system, and magnetron 4 in real time. For example, control unit 6 can monitor the output voltage of high-voltage generator 3 in real time, and when voltage fluctuations occur, promptly adjust the operating parameters of high-voltage generator 3 to ensure stable high-voltage output. Control unit 6 can also adjust the working intensity of the cooling system based on temperature detection data of various components to keep the equipment temperature within a reasonable range.

[0054] Power module 5 employs a high-performance power conversion circuit, capable of converting external AC power into a stable DC power supply required by various components of the equipment. Power module 5 features multiple protection functions, including overvoltage protection, overcurrent protection, and short-circuit protection. When an external power supply malfunctions or an internal equipment fault occurs, power module 5 can promptly cut off the power supply or limit current and voltage to prevent equipment damage and ensure safe operation of the equipment.

[0055] The specific implementation process of the high-pressure contact-type cooling microwave deep fascia therapy device of the present invention is as follows:

[0056] When using this device to perform deep fascia treatment on patients, first move the device to a suitable position in the treatment room using the bottom casters 18. Then, activate the braking device on the casters 18 to secure the device and prevent it from sliding during treatment. Next, the operator sets the corresponding treatment parameters on the touchscreen 2 according to the patient's condition and treatment needs, including treatment time, microwave power, and high-voltage output voltage. After the parameters are set, the operator assists the patient in assuming a suitable treatment position, exposing the treatment area, and cleans the skin of the treatment area to remove dirt and oil, ensuring that the waveguide focusing head 7 can make good contact with the skin.

[0057] The operator holds the waveguide focusing head 7 and presses its PTFE insulated contact surface 11 tightly against the patient's skin at the treatment site, ensuring there are no gaps between the waveguide focusing head 7 and the skin to reduce microwave energy loss. Then, the operator starts the treatment program via the touch screen 2. After receiving the start command, the control unit 6 controls the high-voltage generator 3 to output a stable high voltage, providing the working voltage for the magnetron 4. The magnetron 4 begins to generate microwave energy, which is transmitted to the waveguide focusing head 7 through the connecting wire. After being focused by the waveguide focusing head 7, it acts on the patient's deep fascia tissue.

[0058] During treatment, the control unit 6 monitors the operating status of each component of the equipment and the temperature of the patient's treatment site in real time, displaying information such as treatment time, microwave power, and equipment temperature on the touchscreen 2. If any abnormality occurs (such as unstable high-voltage output, excessive temperature, or abnormal microwave power), the control unit 6 will immediately issue an alarm signal and automatically stop the treatment program to prevent accidents. Operators must closely monitor the equipment's operating status and the patient's reaction. If the patient experiences discomfort, treatment should be stopped immediately, and appropriate measures should be taken.

[0059] After the treatment session, the equipment automatically stops working. Control unit 6 stops the high-voltage generator 3 from outputting high voltage, and magnetron 4 stops generating microwave energy. The cooling system continues to operate for a period of time until the temperature of all components drops to normal levels, at which point it automatically stops. The operator removes the waveguide focusing head 7 from the patient's treatment area, assists the patient in tidying their clothing, and completes the treatment. After treatment, the operator should clean and maintain the equipment, cleaning the PTFE insulated contact surface 11 of the waveguide focusing head 7, and checking the connections and operating status of all components to ensure the equipment is in good standby condition for future use.

[0060] Conduct penetration performance verification experiments.

[0061] Method: The transmitter head was pressed into a porcine tissue phantom (epidermis / fat / muscle / fascia layer), and the fiber optic temperature sensor was implanted at a depth of 3 cm.

This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
