[0002] Low-temperature plasma is an ionized gas cloud generated by the ionization of gas through an electric field. Its electron temperature is as high as 1-10 eV, while the gas temperature is close to room temperature. It has both biological activity and tissue safety. Research shows that the reactive oxygen and reactive nitrogen generated by low-temperature plasma can inhibit the expression of pro-inflammatory factors, kill pathogenic bacteria, and promote the proliferation of fibroblasts, providing a new direction for the treatment of joint inflammation.

[0003] Traditional plasma treatment devices are bulky and rely on external power supplies, making it difficult to meet the needs of home or outdoor use, restricting the treatment scenarios. The penetration depth of low-temperature plasma is limited, making it difficult to act on deep synovial or cartilage tissues, and there is a lack of real-time temperature monitoring and parameter adaptive mechanisms, resulting in large fluctuations in the treatment effect.

[0021] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0022] Referring to Figures 1-5 As shown, a portable joint inflammation precise treatment instrument based on low-temperature plasma includes a housing 1. A first magnetic adsorption interface 2 is fixedly connected to the lower end of the housing 1. A graphene heat-conducting sheet 3 is fixedly connected to the inside of the housing 1. A circuit board 4 is fixedly connected to the front end of the graphene heat-conducting sheet 3. A plasma generator 5, a battery 6, an ozone neutralization module 7, a communication module 8 and a control chip 9 are fixedly installed at the front end of the circuit board 4. A display screen 10 and two press switches 11 are fixedly connected to the outer surface of the housing 1. A groove is formed at the lower end of the first magnetic adsorption interface 2, and a plurality of uniformly distributed needle-shaped metal contacts 201 are arranged inside the groove. A second magnetic adsorption interface 16 is inserted into the groove. A slot 1601 with the same number as the needle-shaped metal contacts 201 is formed at the upper end of the second magnetic adsorption interface 16. Metal contacts are arranged inside the slot 1601. The needle-shaped metal contacts 201 are inserted into the slot 1601. A probe housing 12 is fixedly connected to the lower end of the second magnetic adsorption interface 16. A micro ultrasonic transducer 14 and an electrode plate 13 are sequentially embedded from top to bottom at the lower end of the probe housing 12. A semiconductor refrigeration sheet 15 is embedded outside the electrode plate 13 inside the probe housing 12.

[0023] Furthermore, the electrode sheet 13 is made of aluminum nitride ceramic copper-clad electrode, which is embedded in the center of the lower end of the probe housing 12 and is electrically connected to the output end of the plasma generator 5 through the first magnetic interface 2 and the second magnetic interface 16. The plasma generator 5 adopts the microfluidic dielectric barrier discharge technology. Through the design of the miniaturized electrode array and gas channel, the ionized gas uses helium as the main gas source and mixes 1%-5% oxygen to stably generate low-temperature plasma at low voltage. The plasma is transmitted to the electrode sheet 13 at the probe end through a wire and acts on the joint inflammation site.

[0024] Furthermore, the ozone neutralization module 7 is a cylindrical filter element, filled with manganese dioxide catalytic particles and activated carbon fibers inside, and is connected to the air outlet of the plasma generator 5 through a gas pipe to adsorb and decompose the ozone generated by the plasma reaction in real time. The activated carbon fibers simultaneously filter nitrogen oxides to avoid the leakage of harmful gases.

[0025] Furthermore, the probe housing 12 is a replaceable multi-shaped probe, with various shapes such as flat and curved. The flat type can be used for the knee joint, and the curved type can be used for finger joints. The probe housing 12 is adsorbed on the housing 1 through the first magnetic interface 2 and the second magnetic interface 16, and the power supply is realized by the contact between the needle-shaped metal contact 201 and the metal contact in the slot 1601. The first magnetic interface 2 and the second magnetic interface 16 itself have a certain magnetic force, which can keep the probe housing 12 stable after adsorption.

[0026] Furthermore, a docking groove 18 is opened at the lower end of the first magnetic interface 2, and a positioning block 17 is fixedly connected to the upper end of the second magnetic interface 16. The positioning block 17 is inserted into the inside of the docking groove 18.

[0027] Furthermore, the docking groove 18 and the positioning block 17 are used to provide a guiding function when installing the probe housing 12. By aligning the positioning block 17 with the docking groove 18 and then docking the second magnetic interface 16 with the first magnetic interface 2, it can ensure that the needle-shaped metal contact 201 is accurately inserted into the slot 1601, thus ensuring the stability of the therapeutic instrument during use.

[0028] Furthermore, a plurality of uniformly distributed heat dissipation grooves 19 are penetrated on the outer surface of the housing 1, and a plurality of micro turbine fans 20 are fixed inside the heat dissipation grooves 19.

[0029] Furthermore, when the device is running, the plasma generator 5 and the battery 6 generate heat. The heat is first transferred to the graphene heat conduction sheet 3 that is closely attached to them. Due to the extremely high thermal conductivity of graphene, the heat can be quickly conducted to the heat dissipation grooves 19. At this time, the micro turbine fans 20 operate to accelerate the flow of air in the heat dissipation grooves 19 and dissipate the heat, thereby reducing the internal temperature of the device and avoiding overheating of the therapeutic instrument during long-term use.

[0030] Furthermore, a plurality of evenly distributed temperature sensors 21 are disposed at the lower end of the probe housing 12 .

[0031] Furthermore, the circuit board 4 serves as an electronic component carrier, integrating a plasma generation circuit, a power management module, a control chip 9 and a communication module 8 to realize signal transmission and energy distribution of each component. The battery 6 provides power to the circuit board 4, and the power management module distributes and adjusts the power to ensure that each component obtains a suitable voltage and current. The control chip 9 is responsible for processing various signals, such as the temperature signal transmitted by the temperature sensor 21, the parameter signal set by the user by pressing the switch 11, etc., and controls the operation of components such as the plasma generator 5, the micro ultrasonic transducer 14 and the semiconductor refrigeration sheet 15 according to these signals. The communication module 8 is used to connect to the mobile phone APP for data transmission to realize remote control and data recording.

[0032] Furthermore, the battery 6 adopts a high-density lithium polymer battery to provide power for the device to meet the needs of portable use.

[0033] Furthermore, the miniature ultrasonic transducer 14 is connected to the circuit board 4 via a wire and is used to emit ultrasonic waves of a specific frequency. When the ultrasonic waves propagate in the tissue, a cavitation effect is generated, causing the tissue gap to temporarily expand, thereby increasing the penetration depth of plasma active particles.

[0034] Furthermore, the temperature sensor 21 is used to collect the temperature of the treatment area in real time and feed it back to the control chip 9. The control chip 9 determines the temperature state of the treatment area based on these data, thereby deciding whether the semiconductor cooling plate 15 needs to be started.

[0035] Furthermore, the semiconductor refrigeration chip 15 is attached to the inner side of the probe housing 12 and is electrically connected to the control chip 9. When the temperature sensor 21 detects that the temperature of the treatment area exceeds 40°C, it transmits a signal to the control chip 9. The control chip 9 issues an instruction to start the semiconductor refrigeration chip 15. The semiconductor refrigeration chip 15 absorbs heat through the thermoelectric effect, reduces the internal temperature of the probe, and thereby reduces the temperature of the treatment area.

[0036] Furthermore, spraying nanobubble gel containing antioxidants before plasma action can reduce surface oxidative stress and release drugs to deep inflammatory areas through bubble rupture.

[0037] Working principle: When in use, select a suitable probe according to the joint type, align the positioning block 17 with the docking groove 18, then dock the second magnetic interface 16 with the first magnetic interface 2. After the connection is completed, turn on the therapeutic instrument by pressing the push switch 11 for controlling power on / off, then press the push switch 11 for controlling the mode to select the treatment mode, and then attach the lower end of the probe housing 12 to the joint skin for treatment. During the treatment process, the plasma generator 5 starts to discharge, and at the same time, the micro ultrasonic transducer 14 works synchronously. The display screen 10 will display the current temperature, remaining time, etc. in real time. If the local temperature of the treatment area exceeds 40 °C, the semiconductor refrigeration sheet 15 will automatically start, and at the same time, the micro turbine fan 20 will accelerate its operation for heat dissipation until the temperature drops back.

[0038] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention.
