[0002] Radiofrequency microneedle is a minimally invasive radiofrequency dot matrix technology that uses tiny microneedles to accurately apply radiofrequency energy to target tissues at different depths. This fundamentally changes the problems of traditional laser and radiofrequency treatments such as uncertain depth, poorly controlled skin damage, and severe energy transmission attenuation. It also avoids side effects such as pigmentation and can be used for facial rejuvenation applications such as skin tightening and scar removal. It can also be used for the treatment of acne and axillary hyperhidrosis.

[0030] See also Figures 1 to 3 As shown, the utility model discloses a specific embodiment of a microneedle electrode device, comprising: a shell 10, a cavity is provided inside the shell 10, a concave cavity is provided on the outer head of the shell 10, a guide boss 11 is provided in the concave cavity, the guide boss 11 is provided with a through hole 12 connected to the cavity, an adsorption groove 13 is formed around the guide boss 11 and the concave cavity, an air groove 14 connected to the adsorption groove 13 is provided on the guide boss 11, a microneedle assembly 20 is provided in the cavity, the microneedle assembly 20 is slidably connected to the cavity up and down, and the microneedle assembly 20 includes at least two microneedles 21, and the microneedles 21 are placed in the cavity and extend toward the through hole 12.

[0031] Specifically, the microneedle electrode can treat different skins, such as facial skin, underarm skin, and abdominal skin. The motor shaft of the external motor extends from the bottom of the housing 10 into the cavity and pushes the microneedle assembly 20 upward. The spring 23 is in a compressed state so that the microneedle 21 extends along the through hole 12. When the microneedle 21 extends out of the guide boss 11, the skin can be treated. When the treatment is completed, the motor shaft retracts, and under the action of the spring 23, the microneedle assembly 20 is driven downward to return to the initial position, and the microneedle 21 retracts into the cavity. Among them, when the microneedle electrode contacts the skin, the skin can be adsorbed through the adsorption groove 13, and the microneedle 21 accurately applies radio frequency energy to the adsorbed skin to achieve skin treatment. Among them, the adsorbed skin will be sunken into the adsorption groove 13. If the skin is sunken too much, it will cause skin damage and other problems. By setting the air groove 14, the area of ​​the adsorbed skin is increased, the suction force is evenly distributed, and the suction force can be reduced, thereby reducing the occurrence of skin damage caused by excessive adsorption, so as to solve the problem that the existing microneedle electrode may cause skin damage during adsorption treatment of the skin.

[0032] Specifically, the number of the microneedles 21 is not specifically limited here and can be set according to actual needs.

[0033] In one embodiment, the microneedle assembly 20 also includes a PCB board 22, a spring 23 and a movable bracket 24, the movable bracket 24 is slidably connected to the cavity up and down, the PCB board 22 is installed on the movable bracket 24, one end of the spring 23 abuts against the movable bracket 24, and the other end abuts against the top wall of the cavity, and the microneedle 21 is fixed to the PCB board 22.

[0034] Specifically, the sliding connection between the movable bracket 24 and the cavity provides the microneedle assembly 20 with freedom of movement in the device, thereby increasing flexibility and adjustability, so that the microneedle 21 moves along the up and down track during operation to meet the needs of different application scenarios. Among them, the spring 23 is used to reset the microneedle assembly 20. In addition, the microneedle 21 is fixed on the PCB board 22, which can ensure the stability and accuracy of the microneedle 21, including the stability of the structure and the accuracy of the RF signal transmission.

[0035] In one embodiment, a temperature sensor 25 is further connected to the PCB board 22 near the microneedle 21 .

[0036] Specifically, the temperature sensor 25 is used to detect the temperature of the microneedle 21. During the treatment process, the microneedle 21 may need to be operated within a specific temperature range to ensure the effectiveness and stability of the treatment. By real-time monitoring of the temperature and taking corresponding measures, such as adjusting the temperature of the operating environment or changing the operating parameters, the successful treatment of the microneedle 21 can be ensured. In addition, in some cases, the operation of the microneedle 21 may be affected by the temperature and cause danger or adverse effects. By monitoring the temperature and issuing an alarm or stopping the operation in time, the safety of the user and the object of operation can be protected; for example: when the ambient temperature is too high, the skin of the microneedle assembly 20 or the object of operation may be damaged, so it is very important to take measures in time to prevent burns due to excessive temperature.

[0037] In one embodiment, the PCB board 22 is further connected to a counting sensor 26 .

[0038] Specifically, the counting sensor 26 is used to record the number of times the microneedle 21 is used for treatment. In some applications, the number of times the microneedle 21 is used may be limited, because frequent use may cause the microneedle 21 to wear or fail. By monitoring the number of times the microneedle 21 is used, the user can be reminded to perform maintenance or replace the microneedle 21 in a timely manner to ensure the accuracy and effectiveness of the operation. In addition, in some applications, the number of times the microneedle 21 is used during treatment may be limited, and a limited number of times is required to achieve a therapeutic effect. Therefore, by monitoring the number of times the microneedle 21 is used, the user can be reminded in a timely manner.

[0039] In one embodiment, a fixing plate 15 is disposed at the bottom of the cavity, and a spring ejector 27 is further connected to the PCB board 22 , and the spring ejector 27 is connected to the fixing plate 15 .

[0040] Specifically, the fixing plate 15 is a circuit board, one side of the fixing plate 15 is electrically connected to the spring pin 27, and the other side is electrically connected to the therapeutic device. In addition to fixing the microneedle assembly 20, the fixing plate 15 also transmits the temperature signal of the temperature sensor 25 and the counting signal of the counting sensor 26 to the therapeutic device, and transmits the radio frequency signal of the therapeutic device to the microneedle 21. In addition, an opening is provided on the fixing plate 15 so that the motor shaft can extend into the cavity and contact the movable bracket 24.

[0041] In one embodiment, an adsorption tube 16 is further disposed on the outer side of the shell 10 , and the adsorption tube 16 is connected to the adsorption tank 13 .

[0042] Specifically, the therapeutic apparatus is provided with an adsorption device, which is connected to the adsorption tank 13 through the adsorption tube 16. The gas in the adsorption tank 13 and the gas tank 14 is sucked by the adsorption device, so that the adsorption tank 13 and the gas tank 14 form a negative pressure environment, and the negative pressure environment can adsorb the skin, thereby achieving the function of adsorbing the skin. When the skin is adsorbed, the microneedle 21 passes through the through hole 12 to perform radio frequency treatment on the adsorbed skin. When the skin is adsorbed, it can ensure that the treatment site is not offset, thereby improving the stability and effect of skin treatment.

[0043] In one embodiment, the air groove 14 is disposed on the upper surface of the guide boss 11 and is located between adjacent microneedles 21 .

[0044] Specifically, a plurality of microneedles 21 are evenly distributed on the upper surface of the guide boss 11 , and air grooves 14 are formed between adjacent microneedles 21 to provide more adsorption area.

[0045] In one embodiment, the air groove 14 is arranged horizontally or vertically or horizontally and vertically crosswise, and the air groove 14 only needs to be connected with the adsorption groove 13. The air groove 14 and the adsorption groove 13 work together to adsorb the skin, thereby increasing the area of ​​the skin adsorbed.

[0046] In one embodiment, the concave cavity and the guide boss 11 are both square in shape.

[0047] Specifically, the square-shaped cavity and the guide boss 11 have a larger contact area and can provide more adsorption area.

[0048] Specifically, the guide boss 11 and the housing 10 are an integrally formed structure, thereby improving the stability and rigidity of the overall structure. In addition, the integrally formed structure generally has better durability. Compared with a structure assembled by a connector, the integrally formed structure is less likely to loosen, fall off or break, thereby extending the service life of the device.

[0049] The utility model also discloses a therapeutic apparatus, comprising the micro-needle electrode device as described above.

[0050] Specifically, the therapeutic device can treat different skins, such as facial skin, underarm skin, and abdominal skin. The motor shaft of the stepper motor extends from the bottom of the housing 10 into the cavity and pushes the movable bracket 24 upward. At this time, the spring 23 is in a compressed state, and the microneedle 21 extends along the through hole 12. When the microneedle 21 extends out of the guide boss 11, the skin can be treated; when the treatment is completed, the motor shaft retracts, and under the action of the spring 23, the movable bracket 24 is driven downward to return to the initial position, and the microneedle 21 retracts into the cavity. Among them, when the microneedle 21 contacts the skin, the skin can be adsorbed through the adsorption groove 13, and the microneedle 21 accurately applies radio frequency energy to the adsorbed skin to achieve skin treatment. Among them, the adsorbed skin will be sunken into the adsorption groove 13. If the skin is sunken too much, it will cause skin damage and other problems. By setting the air groove 14, the area of ​​the adsorbed skin is increased, the suction force is evenly distributed, and the suction force can be reduced, thereby reducing the occurrence of skin damage caused by excessive adsorption, so as to solve the problem that the existing microneedle electrode will cause skin damage during adsorption treatment of the skin, so that the therapeutic device can better meet the needs and improve the treatment effect.

[0051] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
