Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. Throughout this application, unless otherwise specified, "plurality" means two or more.

[0040] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0041] like Figure 1-Figure 7 As shown, the present invention provides a fractional radio frequency treatment device, comprising: a treatment head 100 and a treatment host, the treatment head 100 being installed on the treatment host; the treatment head 100 comprising: a shell 1; a base plate 2, the base plate 2 being snap-connected to the shell 1, a cavity being provided between the base plate 2 and the shell 1; an electrode fixing plate 3, a plurality of which are provided, and the electrode fixing plates 3 are stacked in the cavity; a plurality of radio frequency electrode sheets 4, the radio frequency electrode sheets 4 being arranged in an array on the electrode fixing plates 3, the front end of the radio frequency electrode sheet 4 extending through the first through hole 11 of the shell 1, and the rear end of the radio frequency electrode sheet 4 extending through the second through hole 21 of the base plate 2; a control module, the control module being connected to the radio frequency electrode sheet 4, and the control module being used to independently control the radio frequency output of each radio frequency electrode sheet 4.

[0042] The present invention enables precise fractional radiofrequency treatment of the skin, improving treatment efficiency and effectiveness. The stacked electrode mounting plates 3 design allows for easy adjustment of the number and layout of the radiofrequency electrodes 4 to suit different treatment needs. Furthermore, the control module independently controls the radiofrequency output of each radiofrequency electrode 4, enabling precise regulation of treatment parameters and ensuring treatment accuracy and safety.

[0043] In some embodiments of the present application, the electrode fixing plate 3 includes an upper fixing plate 31, an intermediate fixing plate 32 and a lower fixing plate 33. The intermediate fixing plate 32 is provided with first clamping columns 321 on the upper and lower sides. The RF electrode sheet 4 is provided with a first groove 41. The first groove 41 matches the first clamping column 321. The RF electrode sheet 4 is fixed on the intermediate fixing plate 32 through the first groove 41 and the first clamping column 321. The upper fixing plate 31 and the lower fixing plate 33 are provided on the upper and lower sides of the intermediate fixing plate 32 and limit the RF electrode sheet 4.

[0044] It is understood that the stacked design of the upper, middle, and lower fixing plates 31, 32, and 33 further enhances the stability and reliability of the electrode fixing plate 3. The cooperation between the first clamping post 321 and the first groove 41 not only simplifies the installation process of the RF electrode sheet 4 but also ensures the precise positioning of the RF electrode sheet 4 on the electrode fixing plate 3. The limiting effect of the upper and lower fixing plates 31, 33 effectively prevents the RF electrode sheet 4 from shifting or falling off during treatment, further improving the safety and stability of treatment.

[0045] In some embodiments of the present application, a connecting plate 311 is provided on both sides of the upper fixing plate 31 and the lower fixing plate 33, and a second clamping column 312 and a second groove 313 are provided on the connecting plate 311. The second clamping columns 312 and the second groove 313 on the upper fixing plate 31 and the lower fixing plate 33 are arranged alternately, and the second clamping column 312 of the lower fixing plate 33 is clamped with the second groove 313 of the upper fixing plate 31, and the second clamping column 312 of the upper fixing plate 31 is clamped with the second groove 313 of the upper group of lower fixing plates 33.

[0046] It can be understood that the staggered engagement design of the second engaging posts 312 and the second recesses 313 on the connecting plate 311 achieves a secure connection between the upper fixing plate 31, the intermediate fixing plate 32, and the lower fixing plate 33, further enhancing the structural strength of the entire electrode fixing plate 3. This engaging arrangement not only facilitates assembly and disassembly but also ensures stability while allowing the physician to quickly adjust the layout of the RF electrode pads 4 according to treatment needs.

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

[0048] It can be understood that the coordinated design of the limiting plate 12 inside the housing 1 and the limiting groove 314 on the connecting plate 311 achieves precise positioning and secure installation of the electrode fixing plate 3. 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 spacing between the electrode fixing plate 3 and the housing 1, thereby optimizing the transmission efficiency of the radiofrequency energy.

[0049] In some embodiments of the present 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 arranged in a triangular shape.

[0050] In this embodiment, to ensure that the energy of the RF electrode sheet 4 effectively penetrates the dermis, multiple triangular tips 42 are designed at the front end of the electrode sheet. These tips 42 contact the skin, allowing the electrode sheet to moderately penetrate the epidermis and further penetrate the dermis, achieving effective energy transfer. The triangular tips 42 design effectively prevents the RF electrode sheet 4 from excessively penetrating the dermis, thereby reducing potential damage to the skin.

[0051] As can be understood, the triangular tip 42 at the front end of the RF electrode 4 enables more precise application of the dermal tissue, enabling micro-treatment of the skin. This not only improves treatment accuracy but also reduces discomfort during treatment, enhancing the patient's treatment experience. Furthermore, the triangular tip 42 better adapts to the subtle irregularities of the skin surface, ensuring that RF energy is evenly and effectively delivered to the skin, thereby enhancing the therapeutic effect.

[0052] In some embodiments of the present application, a connection connector 43 is provided at the rear end of the radio frequency electrode sheet 4 , and the connection connector 43 is used to be electrically connected to the treatment host.

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

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

[0055] It is understood that the snap-fit design of the positioning plate 22 on the inner side of the base plate 2 and the housing 1, as well as the connection design of 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 the precise positioning between the base plate 2 and the housing 1, but also enhances the structural strength of the connection, preventing loosening or falling off during treatment.

[0056] In some embodiments of the present application, the control module includes a controller, an electronic switch, a radio frequency power module and a human-computer interaction module. The controller is connected to the electronic switch, the radio frequency power module and the human-computer interaction module. The electronic switch is configured to achieve the connection between the radio frequency power module and the radio frequency electrode sheet by turning on and off. The controller is configured to receive input instructions from the human-computer interaction module and control the electronic switch according to the input instructions to achieve radio frequency treatment of the radio frequency electrode sheet.

[0057] In this embodiment, the controller uses a high-performance MCU, which is installed on the treatment host control mainboard, and its I / O port is initialized and configured through programming software so that it can communicate and control stably and reliably with the electronic switch, RF power module and human-computer interaction module.

[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 create the electronic switch circuit. Ensure that each electronic switch has good soldering quality and correct pin connections. Perform necessary electrical performance tests, such as on-resistance and withstand voltage tests, to ensure proper functioning of the electronic switch module.

[0059] RF Power Module: Install the RF power module in the control chassis and set parameters and debug according to its technical manual. Connect the module to a load, oscilloscope, and other test equipment to check whether the module's output power, frequency stability, and other indicators meet requirements. Adjust the matching relationship between the module and the electronic switch to ensure efficient transmission of RF energy to the RF electrodes.

[0060] Human-computer interaction module: Design and manufacture the human-computer interaction module by selecting appropriate display screens, buttons, touch panels, and other components. Connect the human-computer interaction module to the MCU and implement various operation interfaces and function menus through programming, such as the treatment parameter setting interface, dot matrix image selection interface, and treatment progress display interface, to facilitate user operation and viewing of system information.

[0061] It is understandable that the control module integrates the controller, electronic switch, RF power module and human-computer interaction module to form an efficient and intelligent treatment control system. As the core component, the controller is responsible for receiving and processing instructions from the human-computer interaction module, and accurately controlling the on and off of the electronic switch according to the instruction requirements, thereby achieving precise management of the connection between the RF power module and the RF electrode sheet. The rapid response characteristics of the electronic switch ensure the immediate output and shutdown of RF energy, providing a flexible and precise control method for the treatment process. The RF power module is responsible for providing stable and efficient RF energy to ensure the effectiveness and safety of the treatment. The human-computer interaction module provides users with an intuitive and convenient operation interface, allowing doctors to easily set treatment parameters and monitor the treatment progress in real time, greatly improving the convenience and accuracy of treatment.

[0062] In this embodiment, a temperature sensor module can be added, and multiple temperature sensors can be reasonably arranged around the radio frequency electrode sheet or in contact with the skin. The signal output end of the temperature sensor is connected to the analog input port of the MCU, and 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 the present application, the controller stores several preset dot matrix graphic templates; the human-computer interaction module is configured to select the dot matrix graphic template or draw a dot matrix graphic, and send the dot matrix graphic template or the drawn dot matrix graphic to the controller; the controller determines the position and state of each RF electrode sheet according to the dot matrix graphic template or the drawn dot matrix graphic, generates a control signal according to the position and state, and sends the control signal to the electronic switch and RF power supply module; the electronic switch and RF power supply module control the RF output of the corresponding RF electrode sheet according to the control signal.

[0064] In this embodiment, the coordinate data of various common dot matrix graphic templates, such as squares, circles, triangles, etc., are pre-stored in the internal memory of the controller. When the user selects a certain dot matrix graphic through the human-computer interaction module, the controller calculates the position and state (on or off) of each RF electrode sheet in the graphic based on the coordinate data of the selected graphic and the layout information of the RF electrode sheet, and sends the corresponding control signal to the electronic switch module, thereby realizing the RF output of the specified dot matrix graphic. For user-defined dot matrix graphics, the controller provides a drawing function. The user can draw the graphics he wants on the human-computer interaction interface by touching or pressing buttons. The controller records the trajectory and coordinate information drawn by the user in real time, and converts it into a control signal for the RF electrode sheet to realize the output of the customized dot matrix graphic.

[0065] It's understandable that the controller's preset dot pattern templates provide significant convenience for doctors. Based on the patient's specific condition, doctors can select the most appropriate dot pattern from the preset templates or freely draw a personalized dot pattern through the human-computer interaction module. This not only simplifies the treatment planning process but also ensures personalized and precise treatment. The controller intelligently identifies and interprets the dot pattern template or the doctor-drawn dot pattern, generating precise control signals based on the position and status of each RF electrode. Based on these control signals, the electronic switch and RF power module precisely control the RF output of each RF electrode, achieving precise treatment of skin tissue.

[0066] In some embodiments of the present application, the controller is further configured to control the RF output of each RF electrode according to a time interval and sequence based on a treatment strategy or a user-defined sequence; 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 the preset treatment strategy or the sequence rules set by the user on the human-computer interaction module, the controller controls the RF output of each RF electrode piece in sequence according to a certain time interval and sequence through timer interruption or cyclic query. For example, in the row-by-row scanning sequence control, the controller first controls the RF electrode pieces in the first row to output RF energy, and after a period of time, controls the output of the RF electrode pieces in the second row, and so on, until all rows of RF electrode pieces have completed one RF output; in the spiral scanning sequence control, the controller controls the output of the RF electrode pieces in sequence according to the spiral trajectory, so that the RF energy gradually diffuses from the center to the outside; in the random scanning sequence control, the controller randomly selects the RF electrode pieces for RF output according to the random number generation algorithm, so that the energy is evenly distributed on the skin. During the sequential control process, the controller monitors the data of the temperature sensor in real time, and dynamically adjusts the output power and time interval according to the changes in skin temperature to ensure the safety and effectiveness of the treatment.

[0068] As you can imagine, the controller's advanced control capabilities further enhance treatment flexibility and personalization. Physicians can choose from a variety of treatment strategies, including progressive scanning, spiral scanning, or random scanning, based on treatment needs and patient skin conditions. These strategies not only ensure uniform and comprehensive treatment but also enable real-time adjustment of treatment parameters based on skin tissue response, optimizing treatment outcomes. Furthermore, the controller supports user-defined sequencing, allowing physicians to flexibly set the output sequence and time intervals of the RF electrodes based on specific circumstances, enabling precise control over the treatment process.

[0069] In this embodiment, the temperature data transmitted by the temperature sensor module can also be collected in real time through the analog input port and converted into digital quantities for processing. During the treatment process, the controller continuously compares the collected temperature data with the preset safety temperature threshold. When the skin temperature approaches or exceeds the safety threshold, the controller immediately takes measures to adjust it. For example, the skin temperature can be quickly reduced to a safe range by reducing the output power of the RF power module, suspending the RF output of some RF electrodes, or extending the output interval time. At the same time, the controller dynamically adjusts the treatment parameters, such as initial output power, power increment rate, treatment time, etc., according to the temperature change trend and historical data, to achieve personalized temperature control and optimization of treatment effects.
