[0002] With the development of cosmetic medical technology, fractional radiofrequency (RF) technology has been widely used in the medical aesthetics field due to its precise energy output and significant skin tightening and repair effects. However, traditional fractional RF treatment devices have the following shortcomings: Low electrode control precision: Traditional devices mostly use fixed electrode arrays, making it impossible to independently control the RF output of individual electrodes, thus making it difficult to achieve precise treatment of complex fractional patterns. Poor flexibility: The fixed electrode layout makes it impossible to adjust the fractional density and energy distribution according to different skin problems (such as wrinkles, scars, enlarged pores, etc.) or treatment areas (such as face, neck, hands, etc.). Complex operation: Relying on manual experience to adjust treatment parameters, lacking intelligent control and personalized treatment plans, resulting in a poor user experience.

[0040] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0041] like Figures 1-7 As shown, the present invention provides a fractional radiofrequency therapy device, comprising: a treatment head 100 and a treatment host, wherein the treatment head 100 is mounted on the treatment host; the treatment head 100 includes: a shell 1; a base plate 2, the base plate 2 being snapped into the shell 1, and a cavity being provided between the base plate 2 and the shell 1; electrode fixing plates 3, wherein several groups are provided, and the electrode fixing plates 3 are stacked in the cavity; radiofrequency electrode pads 4, wherein multiple radiofrequency electrode pads 4 are arranged in an array on the electrode fixing plates 3, the front end of the radiofrequency electrode pads 4 extending through a first through hole 11 of the shell 1, and the rear end of the radiofrequency electrode pads 4 extending through a second through hole 21 of the base plate 2; and a control module, the control module being connected to the radiofrequency electrode pads 4, and the control module being used to independently control the radiofrequency output of each radiofrequency electrode pad 4.

[0042] This invention enables precise fractional radiofrequency treatment of the skin, improving treatment efficiency and effectiveness. The stacked electrode mounting plate 3 design allows for easy adjustment of the number and layout of the radiofrequency electrode pads 4 to meet different treatment needs. Simultaneously, the control module can independently control the radiofrequency output of each radiofrequency electrode pad 4, achieving precise control of treatment parameters and ensuring the accuracy and safety of the treatment.

[0043] In some embodiments of this application, the electrode fixing plate 3 includes an upper fixing plate 31, a middle fixing plate 32, and a lower fixing plate 33. The middle fixing plate 32 is provided with first locking posts 321 on its upper and lower sides. The radio frequency electrode sheet 4 is provided with a first groove 41, which matches the first locking posts 321. The radio frequency electrode sheet 4 is fixed on the middle fixing plate 32 through the cooperation of the first groove 41 and the first locking posts 321. The upper fixing plate 31 and the lower fixing plate 33 are provided on the upper and lower sides of the middle fixing plate 32 and limit the radio frequency electrode sheet 4.

[0044] Understandably, the stacked design of the upper fixing plate 31, the middle fixing plate 32, and the lower fixing plate 33 further enhances the stability and reliability of the electrode fixing plate 3. The engagement of the first snap-fit ​​post 321 with the first groove 41 not only simplifies the installation process of the radiofrequency electrode pad 4 but also ensures the precise positioning of the radiofrequency electrode pad 4 on the electrode fixing plate 3. The limiting effect of the upper fixing plate 31 and the lower fixing plate 33 effectively prevents the radiofrequency electrode pad 4 from shifting or falling off during treatment, further improving the safety and stability of the treatment.

[0045] In some embodiments of this application, connecting plates 311 are provided on both sides of the upper fixing plate 31 and the lower fixing plate 33. The connecting plates 311 are provided with second snap-fit ​​posts 312 and second grooves 313. The second snap-fit ​​posts 312 and second grooves 313 on the upper fixing plate 31 and the lower fixing plate 33 are staggered. The second snap-fit ​​posts 312 of the lower fixing plate 33 are snapped into the second grooves 313 of the upper fixing plate 31, and the second snap-fit ​​posts 312 of the upper fixing plate 31 are snapped into the second grooves 313 of the previous set of lower fixing plates 33.

[0046] Understandably, the staggered snap-fit ​​design of the second snap-fit ​​post 312 and the second groove 313 on the connecting plate 311 achieves a firm connection between the upper fixing plate 31, the middle fixing plate 32, and the lower fixing plate 33, further enhancing the structural strength of the entire electrode fixing plate 3. This snap-fit ​​method not only facilitates assembly and disassembly but also allows doctors to quickly adjust the layout of the radiofrequency electrode pads 4 according to treatment needs while ensuring stability.

[0047] In some embodiments of this application, a plurality of limiting plates 12 are provided inside the outer shell 1. The limiting plates 12 are used to limit the electrode fixing plate 3. A limiting groove 314 is provided on the connecting plate 311. The limiting plates 12 and the limiting groove 314 cooperate to install the electrode fixing plate 3 in the cavity.

[0048] Understandably, the precise positioning and stable installation of the electrode fixing plate 3 are achieved through the cooperation of the limiting plate 12 inside the outer shell 1 and the limiting groove 314 on the connecting plate 311. The presence of the limiting plate 12 not only prevents the electrode fixing plate 3 from shaking or shifting during treatment, but also ensures an appropriate distance between the electrode fixing plate 3 and the outer shell 1, thereby optimizing the transmission efficiency of radio frequency energy.

[0049] In some embodiments of this application, the front end of the radio frequency electrode sheet 4 is provided with a plurality of tips 42 for contacting the skin, and the tips 42 are configured as triangles.

[0050] In this embodiment, to ensure that the energy of the radiofrequency electrode 4 effectively penetrates into the dermis of the skin, the front end of the electrode 4 is designed with multiple triangular tips 42. These tips 42 contact the skin, allowing the electrode 42 to moderately penetrate the epidermis and then penetrate deep into the dermis, achieving effective energy transfer. The triangular tip design effectively prevents the radiofrequency electrode 4 from excessively intruding into the dermis, thereby reducing potential damage to the skin.

[0051] Understandably, the triangular tip 42 at the front end of the radiofrequency electrode pad 4 allows for more precise application to skin tissue, enabling micro-treatment of the skin. This not only improves treatment accuracy but also reduces discomfort during the treatment process, enhancing the patient's experience. Simultaneously, the triangular tip 42 better adapts to the minute irregularities on the skin surface, ensuring that radiofrequency energy is delivered evenly and effectively to the skin tissue, thereby enhancing the treatment effect.

[0052] In some embodiments of this application, a connector 43 is provided at the rear end of the radiofrequency electrode 4, which is used for electrical connection with the treatment host.

[0053] In this embodiment, the connector 43 at the rear end of the radiofrequency electrode pad 4 enables a convenient and reliable connection between the radiofrequency electrode pad 4 and the treatment host. This simplifies the device connection process and ensures the stability and efficiency of the radiofrequency signal during transmission. The connector 43 allows doctors to quickly and accurately complete the device connection, reducing pre-treatment preparation time and improving treatment efficiency.

[0054] In some embodiments of this application, a positioning plate 22 is provided on the inner side of the base plate 2, and a positioning post 23 is provided on the outer side of the base plate 2. The base plate 2 is snapped into the outer shell 1 through the positioning plate 22, and the base plate 2 is connected to the treatment host through the positioning post 23.

[0055] Understandably, the snap-fit ​​design between the positioning plate 22 on the inner side of the base plate 2 and the outer shell 1, as well as the connection design between the positioning post 23 on the outer side of the base plate 2 and the treatment host, achieve a stable connection between the treatment head 100 and the treatment host. The positioning plate 22 not only ensures precise positioning between the base plate 2 and the outer shell 1, but also enhances the structural strength of the connection, preventing loosening or detachment during treatment.

[0056] In some embodiments of this application, the control module includes a controller, an electronic switch, a radio frequency power module, and a human-machine interaction module. The controller is connected to the electronic switch, the radio frequency power module, and the human-machine interaction module. The electronic switch is configured to connect the radio frequency power module and the radio frequency electrode pad by turning on and off. The controller is configured to receive input commands from the human-machine interaction module and control the electronic switch according to the input commands to realize radio frequency therapy on the radio frequency electrode pad.

[0057] In this embodiment, a high-performance MCU is selected as the controller and installed on the control motherboard of the treatment host. Its I / O ports are initialized and configured through programming software so that it can communicate and control the electronic switch, radio frequency power module and human-machine interaction module stably and reliably.

[0058] Electronic Switches: Based on the circuit schematic, select appropriate electronic switching devices such as MOSFETs or relays and solder them onto the circuit board to form the electronic switch circuit. Ensure that the soldering quality of each electronic switch is good, the pin connections are correct, and perform necessary electrical performance tests, such as continuity resistance and withstand voltage tests, to ensure the normal operation of the electronic switch module.

[0059] RF Power Supply Module: Install the RF power supply module in the control chassis and set and debug its parameters according to its technical manual. By connecting a load and testing equipment such as an oscilloscope, check whether the output power, frequency stability and other indicators of the RF power supply module meet the requirements. At the same time, adjust the matching relationship between it and the electronic switch to ensure that the RF energy can be efficiently transferred to the RF electrode plate.

[0060] Human-Machine Interface Module: A human-machine interface module is designed and fabricated using appropriate displays, buttons, and touch panels. This module is connected to the MCU, and various user interfaces and function menus are implemented through programming, such as treatment parameter setting interfaces, dot matrix graphic selection interfaces, and treatment progress display interfaces, facilitating user operation and viewing of system information.

[0061] Understandably, the control module integrates a controller, electronic switches, a radio frequency power supply module, and a human-machine interface module, forming a highly efficient and intelligent treatment control system. The controller, as the core component, is responsible for receiving and processing instructions from the human-machine interface module, precisely controlling the on / off state of the electronic switches according to the instructions, thereby achieving precise management of the connection between the radio frequency power supply module and the radio frequency electrode pads. The rapid response characteristics of the electronic switches ensure the instantaneous output and shutdown of radio frequency energy, providing a flexible and precise control method for the treatment process. The radio frequency power supply module is responsible for providing stable and efficient radio frequency energy, ensuring the effectiveness and safety of the treatment. The human-machine interface module provides users with an intuitive and convenient operating interface, enabling doctors to easily set treatment parameters and monitor the treatment process in real time, greatly improving the convenience and accuracy of the treatment.

[0062] In this embodiment, a temperature sensor module can also be added. Multiple temperature sensors are arranged reasonably around the radio frequency electrode pads or in the area in contact with the skin. The signal output terminal of the temperature sensor is connected to the analog input port of the MCU. The temperature sensor is calibrated and initialized through software programming so that it can accurately measure the skin temperature and transmit it to the MCU for processing.

[0063] In some embodiments of this application, the controller stores several preset dot matrix pattern templates; the human-computer interaction module is configured to select a dot matrix pattern template or draw a dot matrix pattern, and send the dot matrix pattern template or the drawn dot matrix pattern to the controller; the controller determines the position and state of each RF electrode according to the dot matrix pattern template or the drawn dot matrix pattern, generates a control signal according to the position and state, and sends the control signal to the electronic switch and the RF power supply module; the electronic switch and the RF power supply module control the RF output of the corresponding RF electrode according to the control signal.

[0064] In this embodiment, the controller's internal memory pre-stores coordinate data for various common dot matrix pattern templates, such as squares, circles, and triangles. When a user selects a dot matrix pattern through the human-machine interface module, the controller calculates the position and state (on or off) of each RF electrode within the pattern based on the selected pattern's coordinate data and the layout information of the RF electrode pads. It then sends corresponding control signals to the electronic switch module, thereby achieving the RF output of the specified dot matrix pattern. For user-defined dot matrix patterns, the controller provides a drawing function. Users can draw their desired patterns via touch or buttons on the human-machine interface. The controller records the user's drawn trajectory and coordinate information in real time and converts it into control signals for the RF electrode pads, enabling the output of the customized dot matrix pattern.

[0065] Understandably, the pre-set dot matrix pattern template function within the controller provides doctors with immense convenience. Doctors can select the most suitable dot matrix pattern from the preset templates based on the patient's specific condition, or freely draw personalized dot matrix patterns through the human-computer interaction module. This not only simplifies the treatment planning process but also ensures the personalization and precision of the treatment. The controller can intelligently identify and analyze the dot matrix pattern template or the dot matrix pattern drawn by the doctor, generating precise control signals based on the position and state of each radiofrequency electrode. The electronic switches and radiofrequency power supply module then precisely control the radiofrequency output of each radiofrequency electrode based on these control signals, achieving precise treatment of the skin tissue.

[0066] In some embodiments of this application, the controller is further configured to control the radio frequency output of each radio frequency electrode according to a treatment strategy or a user-defined sequence, in accordance with time intervals and sequences; wherein the treatment strategy includes a line-by-line scanning strategy, a spiral scanning strategy, and a random scanning strategy.

[0067] In this embodiment, according to a preset treatment strategy or a sequence rule set by the user on the human-computer interaction module, the controller sequentially controls the radio frequency (RF) output of each RF electrode pad according to a certain time interval and sequence through timer interrupts or cyclic polling. For example, in progressive scan sequence control, the controller first controls the first row of RF electrode pads to output RF energy, maintains it for a period of time, and then controls the second row of RF electrode pads to output, and so on, until all rows of RF electrode pads have completed one RF output; in spiral scan sequence control, the controller controls the output of the RF electrode pads sequentially according to a spiral trajectory, so that the RF energy gradually diffuses from the center outward; in random scan sequence control, the controller randomly selects RF electrode pads for RF output according to a random number generation algorithm, so that the energy is evenly distributed on the skin. During the sequential control process, the controller monitors the data from the temperature sensor in real time and dynamically adjusts the output power and time interval according to changes in skin temperature to ensure the safety and effectiveness of the treatment.

[0068] Understandably, the controller's advanced control functions further enhance the flexibility and personalization of treatment. Doctors can choose different treatment strategies, such as progressive scanning, spiral scanning, or random scanning, based on treatment needs or the patient's skin condition. These strategies not only ensure the uniformity and comprehensiveness of treatment but also allow for real-time adjustment of treatment parameters based on the skin tissue's response, optimizing treatment outcomes. Simultaneously, the controller supports user-defined sequences, allowing doctors to flexibly set the output sequence and time intervals of the radiofrequency electrode pads according to specific circumstances, thereby achieving precise control over the treatment process.

[0069] In this embodiment, temperature data transmitted by the temperature sensor module can also be acquired in real time through an analog input port and converted into digital quantities for processing. During treatment, the controller continuously compares the acquired temperature data with a preset safe temperature threshold. When the skin temperature approaches or exceeds the safe threshold, the controller immediately takes measures to adjust. For example, the skin temperature can be rapidly reduced to a safe range by reducing the output power of the radio frequency power module, pausing the radio frequency output of some radio frequency electrode pads, or extending the output interval. Simultaneously, the controller dynamically adjusts treatment parameters, such as initial output power, power increment rate, and treatment time, based on temperature change trends and historical data to achieve personalized temperature control and optimized treatment effects.
