[0026] Radiofrequency (RF) is a high-frequency electromagnetic wave generated by an alternating electric field that changes its polarity millions of times per second. RF therapy devices generate RF current, which forms a circuit through body tissue between the tip of the working electrode placed on the affected area and diffuse electrodes placed elsewhere. The friction and impact of the ion flow within the tissue generate a magnetic field / heat, manifesting as a field effect / thermal effect within the tissue.

[0027] Existing radiofrequency liposuction devices apply radiofrequency current to the fat layer using hollow needles to dissolve fat. The fat is then extracted from the skin using a syringe or a pump. However, using entirely hollow needles results in insufficient needle strength, making them prone to bending. Therefore, radiofrequency liposuction for the body (such as the abdomen) typically uses needles with a larger diameter and thicker walls. This needle structure presents more inconvenience and difficulties when treating areas with thinner skin, such as facial skin.

[0028] This utility model proposes a radiofrequency microneedle therapy device and a radiofrequency microneedle therapy instrument, which aims to make the insertion of the microneedle component smoother by combining solid needles and hollow needles.

[0029] Please see Figure 1 In one embodiment of this utility model, the radiofrequency microneedle treatment device 100 is used to perform radiofrequency lipolysis on the fat layer. The radiofrequency microneedle treatment device 100 includes a microneedle assembly 1 and a liposuction assembly 2. The microneedle assembly 1 includes a needle plate 11, a solid needle 12 and a hollow needle 13 disposed on the needle plate 11. One end of the solid needle 12 is electrically connected to the needle plate 11, and one end of the hollow needle 13 is electrically connected to the needle plate 11. The other ends of the solid needle 12 and the hollow needle 13 are both used to pierce the fat layer. The liposuction assembly 2 is connected to one end of the hollow needle 13.

[0030] In this embodiment, the microneedle assembly 1 includes a needle plate 11 and solid needles 12 and hollow needles 13 disposed on the needle plate 11. Solid needles 12 and hollow needles 13 are welded to the needle plate 11. The needle plate 11 is equipped with a radio frequency (RF) circuit. One end of the solid needle 12 and one end of the hollow needle 13 are welded to the RF circuit on the needle plate 11, forming a current loop. Both the solid needle 12 and the hollow needle 13 are made of metal, such as stainless steel, which has high strength and can easily penetrate the fat layer. The outer wall near the needle tip can be gold-plated to improve conductivity. The hollow needle 13 is hollow inside, forming a tubular shape. One end of the hollow needle 13 is connected to the liposuction assembly 2. The liposuction assembly 2, through the hollow needle 13, can extract apoptotic fat cells from the fat layer, achieving a slimming effect. The liposuction assembly 2 can use a negative pressure pump or injection piston, etc., to apply negative pressure directly or indirectly to one end of the hollow needle 13 to extract apoptotic fat cells from the fat layer.

[0031] It is understood that the radiofrequency microneedle treatment device 100 in this embodiment includes, but is not limited to, the following situations: the microneedle component 1 and the liposuction component 2 can be integrated into the radiofrequency microneedle treatment head; the microneedle component 1 can be set in the radiofrequency microneedle treatment head, and the liposuction component 2 can be set in the handle, with the handle being detachably connected to the radiofrequency microneedle treatment head so that the liposuction component 2 communicates with the hollow needle 13 of the microneedle component 1; or the treatment head and the handle can be integrally formed, with the microneedle component 1 set on one side of the treatment head and the liposuction component 2 set on one side of the handle, and the liposuction component 2 directly communicating with the hollow needle 13 of the treatment head.

[0032] The technical solution of this utility model utilizes a needle plate 11 of the microneedle assembly 1, which includes solid needles 12 and hollow needles 13, to ensure the strength of the microneedle assembly 1 and make the insertion of the microneedle assembly 1 smoother. The solid needle 12 serves as the positive electrode of the radio frequency output electric field, and the hollow needle 13 serves as the negative electrode of the radio frequency output electric field. A radio frequency electric field is formed between the solid needle 12 and the hollow needle 13 to heat and ablate fat cells. At the same time, the hollow needle 13 is also designed for negative pressure liposuction, connecting to the liposuction assembly 2, to remove the fat cells heated and ablated by the radio frequency electric field from the fat layer, thereby achieving a slimming effect. Under the same output conditions, the solid needle 12 has a solid body, low resistance, and high current, while the hollow needle 13 allows liquid or other tissue to enter the needle body when it is inserted into the tissue, resulting in high resistance and low current. Therefore, the treatment range of the solid needle 12 is larger than that of the hollow needle 13. Correspondingly, the volume of tissue damage and thermal effect is larger. The thermal effect can induce the repair of collagen in the dermis. The combination of solid needle 12 and hollow needle 13 can ensure fat dissolving efficiency and prevent the skin from collapsing due to excessive suction and insufficient repair of collagen in the dermis.

[0033] In the embodiments of this utility model, there are multiple solid needles 12 and multiple hollow needles 13. The multiple solid needles 12 and multiple hollow needles 13 are arranged in an array, with one solid needle 12 and one hollow needle 13 spaced apart.

[0034] In this embodiment, there are multiple solid needles 12 and multiple hollow needles 13, arranged in an array. This array of microneedles enables targeted treatment of the fat layer, improving the efficiency of radiofrequency liposuction. Each hollow needle 13 is spaced apart from each solid needle 12. The solid needle 12 serves as the positive electrode of the radiofrequency output electric field, and the hollow needle 13 serves as the negative electrode. A solid needle 12 and a hollow needle 13 form a current loop, generating a radiofrequency electric field to heat and ablate the fat layer.

[0035] In an embodiment of this utility model, the needle plate 11 is provided with a positive terminal interface and a negative terminal interface, the solid needle 12 is electrically connected to the positive terminal interface, and the hollow needle 13 is electrically connected to the negative terminal interface.

[0036] In this embodiment, the solid needle 12 is electrically connected to the positive terminal interface of the needle plate 11, serving as the positive terminal of the radio frequency output electric field, and the hollow needle 13 is electrically connected to the negative terminal interface of the needle plate 11, serving as the negative terminal of the radio frequency output electric field. The solid needle 12 and the hollow needle 13 form a current loop with the adipose tissue and form a radio frequency electric field in the adipose tissue to heat and ablate the fat layer.

[0037] In an embodiment of this utility model, the radiofrequency microneedle therapy device 100 further includes a motor assembly 3, the driving part of the motor assembly 3 driving the microneedle assembly 1 so that the solid needle 12 and hollow needle 13 of the microneedle assembly 1 pierce into or away from the fat layer.

[0038] In this embodiment, the motor assembly 3 drives the microneedle assembly 1, mainly controlling the forward and backward movement of the microneedle assembly 1. This allows the solid needle 12 and hollow needle 13 of the microneedle assembly 1 to be precisely inserted into the fat layer of the human tissue to be treated, enabling the microneedle assembly 1 to output energy within the fat layer. The motor assembly 3 can be a stepper motor or a lead screw motor, etc., and is not further limited here.

[0039] In an embodiment of this utility model, the radiofrequency microneedle treatment device 100 further includes a main control component, which is electrically connected to the motor component 3, the microneedle component 1, and the liposuction component 2 to coordinate and control the driving of the motor component 3, the radiofrequency output of the microneedle component 1, and the start and stop of the liposuction component 2.

[0040] In this embodiment, the main control component can be an MCU component or a microcomputer component, etc. The main control component can control the drive of the motor component 3, thereby controlling the depth of the microneedle component 1 piercing the fat layer; the main control component can control the radio frequency output of the microneedle component 1, thereby controlling the energy intensity of the radio frequency electric field formed between the solid needle 12 and the hollow needle 13; the main control component can control the start and stop of the liposuction component 2 or the suction intensity of the liposuction component 2, thereby controlling whether fat is suctioned from the fat layer or controlling the speed of fat suction.

[0041] In an embodiment of this utility model, the radiofrequency microneedle treatment device 100 further includes an impedance detection component. The impedance detection component is used to detect the impedance information at the insertion point of the solid needle 12 and / or the hollow needle 13. The impedance detection component is electrically connected or communicatively connected to the main control component to transmit the impedance information to the main control component and control the motor component 3, the microneedle component 1, or the liposuction component 2 through the impedance information.

[0042] In this embodiment, the impedance detection component detects the voltage and current values ​​of the circuit formed by the tips of the hollow needle 13 and the solid needle 12 when the microneedle component 1 is working, and then calculates the impedance of the corresponding area using Ohm's law. At the start of treatment, the microneedle component 1 is placed close to the treatment surface of the body, and the motor component 3 inserts the solid needle 12 and the hollow needle 13 into the skin. Due to the structural information relationship of different layers of human skin, the impedance information of the fat layer is obtained in advance through algorithms and experiments. When the solid needle 12 and the hollow needle 13 are inserted into the fat layer, the impedance display shows a consistent value, indicating that the insertion position of the solid needle 12 and the hollow needle 13 is the fat layer to be treated, allowing for precise insertion of the solid needle 12 and the hollow needle 13 into the target fat layer. The main control component then controls the motor component 3 to stop operating.

[0043] After the solid needle 12 and hollow needle 13 reach the fat layer, the main control component controls the microneedle component 1 to start outputting radiofrequency energy for heating treatment. During the heating process, fat cells will undergo physiological changes. After the fat layer is lipolysis, the impedance changes and the impedance value range of the fat layer becomes smaller, indicating that lipolysis has started. At this time, the main control component controls the liposuction component 2 to extract the fat cells that have been radiofrequency ablated from the human body.

[0044] After liposuction, the impedance detection component re-detects the impedance of the fat layer. If the impedance of the fat layer decreases to the preset impedance range, the treatment effect meets expectations, and the main control component controls the motor component 3 to pull out the microneedle component 1, ending one treatment session. If the impedance of the fat layer is higher than the preset impedance range, the microneedle component 1 remains in place, and the radiofrequency heating treatment and liposuction process are repeated until the impedance of the fat layer is lower than the preset range, thus completing one treatment session.

[0045] In an embodiment of this utility model, the radiofrequency microneedle treatment device 100 further includes a conductivity detection component. The conductivity detection component is used to detect the conductivity information at the insertion point of the solid needle 12 and / or the hollow needle 13. The conductivity detection component is electrically connected or communicatively connected to the main control component to transmit the conductivity information to the main control component and control the motor component 3, the microneedle component 1, or the liposuction component 2 through the conductivity information.

[0046] In this embodiment, the conductivity detection component can detect the conductivity of the insertion layer. The conductivity indicates whether the microneedle component 1 has been inserted into the target layer, whether fat dissolving has begun, and whether the expected fat dissolving effect has been achieved. The main control component can coordinate the insertion and withdrawal of the motor component 3, the radio frequency output and shutdown of the microneedle component 1, and the suction and shutdown of the suction component based on the detected conductivity information of the solid needle 12 and / or hollow needle 13, thereby achieving intelligent liposuction.

[0047] In an embodiment of this utility model, the liposuction assembly 2 includes a liposuction tube 21 and a suction pump 22. The suction pump 22 is connected to one end of the liposuction tube 21, and the hollow needle 13 is connected to the side wall of the liposuction tube 21. The suction pump 22 is used to apply negative pressure to the liposuction tube 21 so as to aspirate apoptotic fat cells through the liposuction tube 21 and the hollow needle 13.

[0048] In this embodiment, the liposuction assembly 2 includes a liposuction cannula 21 and a suction pump 22. The suction pump 22 is connected to one end of the liposuction cannula 21, and the hollow needle 13 is connected to the side wall of the liposuction cannula 21. The suction pump 22 can apply negative pressure to the liposuction cannula 21, so that apoptotic and exudated fat cells can be sucked out by the suction pump 22 through the hollow needle 13 and the liposuction cannula 21. The other side of the suction pump 22 can be connected to a fat collector to temporarily store and process the extracted fat.

[0049] In an embodiment of this utility model, the liposuction assembly 2 further includes an anti-reverse valve 23, which is movably disposed at the connection between the liposuction tube 21 and the hollow needle 13. The anti-reverse valve 23 has a closed state covering the connection and an open state away from the connection.

[0050] And / or, the inner wall of the liposuction cannula 21 is provided with an anti-coagulation coating to prevent fat from solidifying on the inner wall of the liposuction cannula 21.

[0051] In this embodiment, an anti-reverse valve 23 is provided at the connection between the liposuction cannula 21 and the hollow needle 13 to prevent fat from flowing back from the liposuction cannula 21 through the hollow needle 13 into the fat layer, causing subcutaneous infection. The anti-reverse valve 23 is movably installed at the connection between the liposuction cannula 21 and the hollow needle 13. In its natural state, the anti-reverse valve 23 covers the connection to separate the liposuction cannula 21 from the hollow needle 13, preventing fat in the liposuction cannula 21 from flowing back into the hollow needle 13. When the suction pump 22 applies negative pressure to the liposuction cannula 21, the anti-reverse valve 23 moves away from the connection between the liposuction cannula 21 and the hollow needle 13 under the action of negative pressure, connecting the liposuction cannula 21 and the hollow needle 13, allowing apoptotic and exudated fat cells to be sucked into the liposuction cannula 21 through the hollow needle 13.

[0052] Optionally, the inner wall of the liposuction cannula 21 is provided with an anti-coagulation coating to prevent fat from solidifying on the inner wall of the liposuction cannula 21, thereby preventing the liposuction cannula 21 from becoming blocked and causing liposuction failure. The anti-coagulation coating can be a polytetrafluoroethylene coating, which makes it difficult for fat to adhere to the inner wall of the liposuction cannula 21, ensuring a smooth liposuction process; the anti-coagulation coating can also be a heat-insulating coating, such as nano-aerogel heat-insulating coating, which can keep the temperature of fat cells melted by radiofrequency heating stable, thereby preventing fat cells from solidifying again in the liposuction cannula 21, ensuring a smooth liposuction process.

[0053] This utility model also proposes a radiofrequency microneedle therapy device, including the radiofrequency microneedle therapy device 100 as described above and a host electrically connected to the radiofrequency microneedle therapy device 100.

[0054] In this embodiment, the radiofrequency microneedle therapy device includes a main unit and a radiofrequency microneedle therapy device 100. The main unit is provided with a power supply component and a radiofrequency generating component. The radiofrequency microneedle therapy device 100 is electrically connected to the main unit. The power supply component supplies power to the motor component 3 and the suction component. The radiofrequency generating component is electrically connected to the microneedle component 1, so that the microneedle component 1 outputs radiofrequency energy to the fat layer.

[0055] The radiofrequency microneedling device described in this application is suitable for skin fat reduction and liposuction, and is particularly suitable for improving localized skin conditions such as eye bags, double chins, and other facial skin laxity and fat accumulation.
