Clearly, in the process of delivering high-frequency energy to the deep layers of the skin using high-frequency electrodes, if the total output energy required for a unit treatment area (i.e., high-frequency electrode subarray) is the same, the present invention reduces the instantaneous treatment area at each moment by treating each local area of ​​the entire treatment area in stages, thereby reducing instantaneous pain.In addition, in the present application, at least a part of the high-frequency electrode sub-array may output high-frequency energy in the first state or in the second state. By accumulating energy through low-power energy output in the second state, the time required to output high-frequency energy at high power only in the first state until the energy required to achieve treatment is obtained is partially shortened, the total treatment time is shortened, and thereby, when the total output power is the same and the target of the high-frequency energy output at each time is the entire treatment area, the problem that the treatment time becomes long and pain is likely to occur in the human body is solved. Further, throughout the treatment process, the high-frequency electrode sub-array in the second state generates dissipated heat in the treatment area by low-high-frequency energy output at low power or in another manner, improves the uniformity of treatment, and expands the treatment area without enhancing the feeling of pain, thereby enhancing the treatment effect.

Modes for Carrying Out the Invention

[0021] The achievement of the object, functional features and advantages of the present application will be further described in conjunction with the embodiments while referring to the drawings.

[0022] To further clarify the purpose, technical solutions, and advantages of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings of the embodiments; however, it is clear that the embodiments described are only a part of the embodiments of the present application and not all of them.

Unless further limited, the elements limited by the phrase “includes…” do not preclude the existence of other identical elements in a process, method, article, or system containing those elements.

For example, "connection" may be a fixed connection, a detachable connection, a single unit, a mechanical connection, an electrical connection, a direct connection, an indirect connection through an intermediate medium, an internal communication between two elements, or an interaction relationship between two elements.

Therefore, "module," "component," or "unit" may be used interchangeably.

[0025] The specific meanings of the above terms in this application can be understood by those skilled in the art depending on the specific circumstances. Furthermore, the technical solutions of each embodiment may be combined with each other, but this must be based on what a person skilled in the art can achieve.

[0026] Among related technologies, radiofrequency electrode arrays are a safe, efficient, and precise skin treatment that helps improve people's skin. Specifically, radiofrequency electrode arrays can be divided into two types: minimally invasive and non-invasive. Minimally invasive radiofrequency electrode arrays are radiofrequency microneedle arrays that use radiofrequency microneedles as radiofrequency electrodes, where the microneedle heads are inserted into the skin surface, allowing radiofrequency energy to be accurately delivered to the deep tissues of the skin, thereby avoiding the side effects that may occur with conventional radiofrequency treatments. Non-invasive radiofrequency electrode arrays attach the radiofrequency heads directly to the skin surface, creating current channels using the radiofrequency electrodes without damaging the skin, allowing the current to pass through the deep tissues of the skin to achieve treatment. In the process of delivering radiofrequency energy to the deep layers of the skin using radiofrequency electrodes to achieve the desired therapeutic effect, if the total output power is the same, and the target of the radiofrequency energy output at each time is the entire treatment area, the treatment time will be longer, and it will be more likely to cause pain in the human body. Among these, pain is the result of a combination of factors and is positively correlated with treatment time, treatment area, and power. In the case of whole-body treatment (i.e., the target of the high-frequency energy output at each time point is the entire treatment area), the treatment area and treatment time are important factors in generating the sensation of pain when compared to single-point treatment (i.e., the target of the high-frequency energy output at each time point is a localized treatment area).

[0027] Accordingly, the present invention provides a solution that divides a high-frequency electrode array into a plurality of high-frequency electrode subarrays, selects one or more high-frequency electrode subarrays from the plurality of high-frequency electrode subarrays by a first subarray determination module to be the target high-frequency electrode subarray corresponding to the initial output period, controls the target high-frequency electrode subarray corresponding to the initial output period by a control module to output high-frequency energy in a first state, and controls at least a portion of the remaining high-frequency electrode subarrays other than the target high-frequency electrode subarray corresponding to the initial output period to be in a second state. Simultaneously with or after determining the target high-frequency electrode subarray corresponding to the initial output period, the second subarray determination module uses the target high-frequency electrode subarray as the history high-frequency electrode subarray, and loops through determining the target high-frequency electrode subarray corresponding to the new output period from the remaining high-frequency electrode subarrays other than all of the history high-frequency electrode subarrays in the high-frequency electrode array until all of the high-frequency electrode subarrays in the high-frequency electrode array become history high-frequency electrode subarrays. For each new output cycle, if the current output cycle is a new output cycle, the control module controls the target high-frequency electrode subarray corresponding to the new output cycle to output high-frequency energy in a first state, controls at least a portion of the remaining high-frequency electrode subarrays other than the target high-frequency electrode subarray and the hysteresis high-frequency electrode subarray corresponding to the current output cycle to be in a second state, and controls the hysteresis high-frequency electrode subarray to be in a second or third state. In other words, the control module is used to control the target high-frequency electrode subarray corresponding to the current output cycle (which can be either the initial cycle or a new output cycle, as described above) to switch to a first state and output high-frequency energy, controls the hysteresis high-frequency electrode subarray (if any) to be in a second or third state, and controls at least a portion of the remaining high-frequency electrode subarrays other than the target high-frequency electrode subarray and the hysteresis high-frequency electrode subarray corresponding to the current output cycle to be in a second state.

[0028] Clearly, in the process of delivering high-frequency energy to the deep layers of the skin using high-frequency electrodes, if the total output energy required for the high-frequency electrode subarray is the same, at least a portion of the high-frequency electrode subarray in this application may have output high-frequency energy in both the first and second states. In this application, by treating each local area of ​​the entire treatment area in stages, the instantaneous treatment area at each time is reduced, thereby reducing instantaneous pain. Furthermore, by accumulating energy through low-power energy output in the second state, the time required to output high-power high-frequency energy in the first state alone until the energy necessary to achieve treatment is obtained is partially shortened, thereby shortening the total treatment time. This avoids causing pain to the human body due to excessively long treatment duration in local areas, and solves the problem that, when the total output power is the same, if the target of the high-frequency energy output at each time is the entire treatment area, the treatment time becomes longer and the human body is more likely to experience pain. Furthermore, throughout the treatment process, the low-frequency energy output by the high-frequency electrode subarray in the second state, either at low power or by other means, not only shortens the operating time during which high-frequency energy is output in the first state, but also generates dissipative heat in the treatment area, improving the uniformity of the treatment, expanding the treatment area without increasing the sensation of pain, and enhancing the treatment effect.

[0029] The present invention will be further described below with reference to several specific examples.

[0030] As shown in Figure 1, in a first embodiment, the present application provides an embodiment of a high-frequency electrode array control device. As shown in Figures 1 and 2, Figure 1 shows a schematic diagram of the structure of the first embodiment of the high-frequency electrode array control device of the present application, and Figure 2 shows a schematic diagram of the structure of a high-frequency therapeutic device in which the high-frequency electrode array control device of the present application is used.

[0031] In this embodiment, the high-frequency electrode array control device is used in a high-frequency therapeutic device, which includes a high-frequency power supply 40 and a high-frequency electrode array 50, the high-frequency electrode array 50 being electrically connected to the high-frequency power supply 40, and the high-frequency electrode array 50 including a plurality of high-frequency electrode subarrays, each containing at least one high-frequency electrode.

[0032] The high-frequency power supply 40 may consist of only one unit, that is, one high-frequency power supply 40 that supplies power to the high-frequency electrode array 50. The high-frequency power supply 40 may consist of multiple individually controllable sub-high-frequency power supplies, each of which can individually control the connection or disconnection of one or more high-frequency electrode sub-arrays and control their output power.

[0033] The high-frequency electrode array 50 generally comprises a series of interconnected, minute, and regularly arranged high-frequency electrodes, consisting of insulating material and metal. The metal portion is used to deliver high-frequency energy to the deeper layers of the skin. It is understood that such an arrangement of high-frequency electrodes delivers high-frequency energy uniformly and accurately to the skin during the treatment process, thereby stimulating collagen production and skin regeneration and reconstruction. The high-frequency electrode array 50 may be positioned at various locations on the high-frequency treatment device. Specifically, this position is determined by the design of the device, and typically, the high-frequency electrode array 50 is positioned on the treatment side of the handle of the high-frequency treatment device.

[0034] Furthermore, the operator can pre-divide the high-frequency electrodes in the high-frequency electrode array 50 to obtain multiple high-frequency electrode subarrays, and the high-frequency electrode subarrays can be used as the minimum output unit. In a high-frequency electrode device, the operating mode can be classified into unipolar mode and bipolar mode. When the high-frequency electrode device operates in unipolar mode, the number of high-frequency electrodes contained in each high-frequency electrode subarray is at least one. When the high-frequency electrode device operates in bipolar mode, the number of high-frequency electrodes contained in each high-frequency electrode subarray is at least two, that is, there are two high-frequency electrodes with opposite polarities (one positive, the other negative). Of course, a high-frequency electrode subarray may contain more than the minimum number mentioned above, for example, three or four high-frequency electrodes.

[0035] The high-frequency electrode array control device includes a first sub-array determination module 10, a second sub-array determination module 20, and a control module 30. These will be described in detail below.

[0036] The first sub-array determination module 10 is used to determine a target high-frequency electrode sub-array corresponding to the initial output period from among the high-frequency electrode arrays 50.

[0037] Specifically, the initial output period is the output period when the high-frequency electrode array 50 starts operating, the target high-frequency electrode subarray is a high-frequency electrode subarray included in the high-frequency electrode array 50, and determining the target high-frequency electrode subarray corresponding to the initial output period from among the high-frequency electrode array 50 means determining the high-frequency electrode subarray that outputs high-frequency energy in the first state when the high-frequency electrode array 50 starts operating. At least a portion of the remaining high-frequency electrode subarrays of the high-frequency electrode array 50 outputs high-frequency energy in the second state.

[0038] Preferably, to facilitate control of the uniformity of the therapeutic energy distribution, the number of high-frequency electrodes in each target high-frequency electrode subarray is equal, or the difference in the number is less than a preset threshold. The difference in the number of high-frequency electrodes in the target high-frequency electrode subarray is usually related to the total number of high-frequency electrodes included in the high-frequency electrode array 50. In short, this difference in number needs to be controlled to 5 or less (i.e., the preset threshold is 5) so that the difference in instantaneous therapeutic area and power density (power per unit area) is not too large.

[0039] In the initial stages of treatment, all high-frequency electrode subarrays are selectable, meaning they are all selectable high-frequency electrode subarrays. In this embodiment, the target high-frequency electrode subarray corresponding to the initial power cycle is determined from among the high-frequency electrode arrays 50 by a random selection method. Of course, the first subarray determination module 10 may determine the target high-frequency electrode subarray corresponding to the initial power cycle by other methods such as a look-up table, but it is understood that the method for determining the target high-frequency electrode subarray corresponding to the initial power cycle is not limited in this application.

[0040] For the target high-frequency electrode subarray, the high-frequency electrode subarray is selected as the target, and for each output cycle, the high-frequency electrode subarray selected as the target high-frequency electrode subarray outputs high-frequency energy in the first state. In a single output cycle, the target high-frequency electrode subarray may contain one or more high-frequency electrode subarrays. When the target high-frequency electrode subarray contains multiple high-frequency electrode subarrays, at least two high-frequency electrode subarrays are not adjacent to each other to prevent the high-frequency electrode subarrays from leading to a larger treatment area and causing more perceptible pain. By determining multiple non-adjacent high-frequency electrode subarrays as the target high-frequency electrode subarray, the number of times all of the high-frequency electrode subarrays in the high-frequency electrode array 50 are used as hierarchical high-frequency electrode subarrays is reduced during treatment without causing pain to the human body, i.e., the number of times the second subarray determination module 20 triggers the control module 30 is reduced, thereby shortening the time required for one treatment. Furthermore, for the same total area of ​​the treatment area, the entire treatment area consisting of multiple non-adjacent treatment areas (i.e., high-frequency electrode subarrays) causes less pain to the human body compared to the entire treatment area consisting of adjacent treatment areas.

[0041] The second subarray determination module 20 is used to loop through determining the target high-frequency electrode subarray corresponding to the new output period from among the remaining high-frequency electrode subarrays in the high-frequency electrode array 50, excluding all of the hysteresis high-frequency electrode subarrays, until all of the high-frequency electrode subarrays in the high-frequency electrode array 50 have become hysteresis high-frequency electrode subarrays, with the target high-frequency electrode subarray being the hysteresis high-frequency electrode subarray.

[0042] In a single treatment process, it is sufficient that the high-frequency energy received by the skin region acting on the high-frequency electrode array 50 reaches a predetermined value. Based on this, when determining the target high-frequency electrode subarray to output high-frequency energy in the first state, it is selected from the remaining high-frequency electrode subarrays of the high-frequency electrode array 50, excluding all the hierarchical high-frequency electrode subarrays, thereby avoiding excessive high-frequency energy being transmitted to the same skin region and causing adverse effects on the human body. In this embodiment, the second subarray determination module 20 may be directly connected to the first subarray determination module 10, or the control module 30 may acquire the target high-frequency electrode subarray corresponding to the initial output cycle and determine the target high-frequency electrode subarray corresponding to the new output cycle. Each new output cycle corresponds to a target high-frequency electrode subarray, and the target high-frequency electrode subarray outputs high-frequency energy in the first state during the corresponding output cycle.

[0043] Furthermore, the second subarray determination module 20 may determine multiple new output periods in the loop execution process, and for each new output period, the target high-frequency electrode subarray corresponding to the new output period will output high-frequency energy to act only on a portion of the skin area requiring treatment. From the remaining high-frequency electrode subarrays of the high-frequency electrode array 50, excluding all hierarchical high-frequency electrode subarrays, all high-frequency electrode subarrays that are not adjacent to the target high-frequency electrode subarray corresponding to the current output period are determined, and then the target high-frequency electrode subarray corresponding to the new output period is determined from among all high-frequency electrode subarrays that are not adjacent to the target high-frequency electrode subarray corresponding to the current output period. This is understood to avoid causing obvious pain to the local skin because the skin areas on which two consecutive output periods act are close together. In this embodiment, by determining a target high-frequency electrode subarray corresponding to each new output cycle, in the corresponding output cycle, the corresponding target high-frequency electrode subarray outputs high-frequency energy in the first state, all hysteresis high-frequency electrode subarrays are in the second or third state, and at least a portion of the remaining high-frequency electrode subarrays of the high-frequency electrode array 50 are in the second state, thus completing treatment for all areas encompassed by the skin region and achieving the treatment objective.

[0044] In one specific embodiment, the second subarray determination module 20 includes a subarray sorting unit, a second subarray determination unit, and a loop control unit.

[0045] The subarray selection unit is used to determine all high-frequency electrode subarrays from the remaining high-frequency electrode subarrays of the high-frequency electrode array 50, excluding all of the hierarchical high-frequency electrode subarrays, that are not adjacent to the target high-frequency electrode subarray corresponding to the current output period.

[0046] The second subarray determination unit is used to determine the target high-frequency electrode subarray corresponding to the new output period from among all high-frequency electrode subarrays that are not adjacent to the target high-frequency electrode subarray corresponding to the current output period.

[0047] The loop control unit is used to sequentially execute the subarray selection unit and the second subarray determination unit in a loop until all of the high-frequency electrode subarrays in the high-frequency electrode array 50 become hysteresis high-frequency electrode subarrays.

[0048] In short, one complete treatment cycle includes multiple output cycles, such as 1 output cycle, and each output cycle corresponds to one target high-frequency electrode subarray that outputs high-frequency energy in the first state. That is, a total of 1 target high-frequency electrode subarrays are determined. The initial output cycle is the first output cycle, and the target high-frequency electrode subarray corresponding to the first output cycle is the first target high-frequency electrode subarray. The first target high-frequency electrode subarray outputs high-frequency energy in the first state during the initial output cycle. Thus, in the second output cycle, the second target high-frequency electrode subarray outputs high-frequency energy in the first state. The second subarray determination module 20 determines the second target high-frequency electrode subarray corresponding to the second output cycle until the second target high-frequency electrode subarray becomes a hysteresis high-frequency electrode subarray, assuming that all target high-frequency electrode subarrays corresponding to each output cycle from the first to the second output cycle are hysteresis high-frequency electrode subarrays.

[0049] Once the first subarray determination module 10 determines the target high-frequency electrode subarray corresponding to the initial output period, the second subarray determination module 20 may determine multiple target high-frequency electrode subarrays corresponding to several new output periods in a single operation by sequentially looping the subarray selection unit and the second subarray determination unit based directly on the remaining high-frequency electrode subarrays of the high-frequency electrode array 50. Of course, the second subarray determination module 20 may also sequentially run the subarray selection unit and the second subarray determination unit before each current output period ends to determine the target high-frequency electrode subarray corresponding to the next output period, thereby obtaining multiple target high-frequency electrode subarrays corresponding to several new output periods, that is, determining the target high-frequency electrode subarray corresponding to the next output period (if any) before the current output period ends.

[0050] Preferably, the second subarray decision unit is, specifically, This is used to determine a target high-frequency electrode subarray that includes at least two non-adjacent high-frequency electrode subarrays corresponding to a new output period, from among all high-frequency electrode subarrays that are not adjacent to the target high-frequency electrode subarray corresponding to the current output period.

[0051] Similar to determining the target high-frequency electrode subarray corresponding to the initial output cycle, in this embodiment, for a new output cycle, the time required for a single treatment can be significantly reduced without causing pain to the patient by determining a target high-frequency electrode subarray that includes at least two non-adjacent high-frequency electrode subarrays corresponding to the new output cycle.

[0052] The control module 30 is used to control the target high-frequency electrode subarray corresponding to the current output cycle so that it switches to a first state and outputs high-frequency energy in the current output cycle, to control the hysteresis high-frequency electrode subarray so that it is in a second or third state, and to control at least a portion of the remaining high-frequency electrode subarray of the high-frequency electrode array 50 so that it is in a second state, wherein the average power output when the high-frequency electrode subarray is in the first state is higher than the average power output when it is in the second state, and the average power when it is in the second state is greater than 0.

[0053] Furthermore, for the same high-frequency electrode subarray, within the same time period, the total high-frequency energy output when the high-frequency electrode subarray is in the first state is far greater than the total high-frequency energy output when it is in the second state. In other words, for each high-frequency electrode subarray, when it outputs high-frequency energy in the first state, it is a high-energy output, and when it outputs high-frequency energy in the second state, it is a low-energy output. In this embodiment, for each high-frequency electrode subarray, even when the high-frequency electrode subarray is in the second state, it still outputs high-frequency energy (in this case, within a unit time, the high-frequency energy output when the high-frequency electrode subarray is in the second state is far less than the high-frequency energy output when it is in the first state), and it was found that this shortens the time required for one treatment by the high-frequency electrode array control device and improves treatment efficiency. In other words, in this embodiment, by controlling with two energy output methods, treatment time can be shortened without causing pain to the human body.

[0054] The current output cycle is either the initial output cycle or a new output cycle. The target high-frequency electrode subarray corresponding to the initial output cycle outputs high-frequency energy in the first state when the high-frequency electrode array 50 starts operating. The target high-frequency electrode subarray corresponding to each new output cycle switches sequentially to the first state after the previous output cycle has ended and outputs high-frequency energy. Therefore, the hierarchical high-frequency electrode subarray gradually expands from zero to encompass all of the high-frequency electrode subarrays of the high-frequency electrode array 50.

[0055] Specifically, with respect to the current output period, if there is currently no history high-frequency electrode subarray (i.e., initial output period), the control module 30 is used to control the target high-frequency electrode subarray corresponding to the current output period so that it switches to a first state and outputs high-frequency energy, and to control at least a portion of the remaining high-frequency electrode subarrays of the high-frequency electrode array 50 so that it is in a second state. If there is currently a history high-frequency electrode subarray (i.e., a new output period), the control module 30 is used to control the target high-frequency electrode subarray corresponding to the current output period so that it switches to a first state and outputs high-frequency energy, and to control the history high-frequency electrode subarray so that it is in a second or third state, and also to control at least a portion of the remaining high-frequency electrode subarrays of the high-frequency electrode array 50 so that it is in a second state.

[0056] Controlling at least a portion of the remaining high-frequency electrode subarrays of the high-frequency electrode array 50, excluding the target high-frequency electrode subarray and the hierarchical high-frequency electrode subarray corresponding to the current output cycle, as the control module 30 is in the second state, includes at least two cases: one in which the control module 30 controls all of the remaining high-frequency electrode subarrays of the high-frequency electrode array 50, excluding the target high-frequency electrode subarray and the hierarchical high-frequency electrode subarray corresponding to the current output cycle, as the control module 30 is in the second state, and the other in which the control module 30 controls a portion of the remaining high-frequency electrode subarrays of the high-frequency electrode array 50, excluding the target high-frequency electrode subarray and the hierarchical high-frequency electrode subarray corresponding to the current output cycle, as the control module 30 is in the second state, and controls the remaining high-frequency electrode subarrays as the control module 30 is in the third state.

[0057] As one specific embodiment, in the second case described above, if the control module 30 controls a portion of the remaining high-frequency electrode subarrays of the high-frequency electrode array 50, excluding the target high-frequency electrode subarray and the hysteresis high-frequency electrode subarray corresponding to the current output cycle, so that it is in the second state, then specifically, the following forms may be included: The target high-frequency electrode subarray corresponding to the next output cycle of the current output cycle is controlled so that it is in the second state. In this control form, the treatment area to which the high-frequency energy output is to be applied in the next output cycle is preheated, ensuring continuity of treatment time for each treatment area, thereby shortening the treatment time and improving the treatment effect. In particular, it is understood that the duration of the first state in the next output cycle is shortened, and the time, intensity, and frequency of pain in the same treatment area are reduced. Optionally, in such embodiments, with respect to the current output cycle, all other high-frequency electrode subarrays (including hysteresis high-frequency electrode subarrays) other than the target high-frequency electrode subarray corresponding to the current output cycle (in this case, the first state) and the target high-frequency electrode subarray corresponding to the next output cycle (in this case, the second state) may be controlled so that it is in the third state.

[0058] In this embodiment, the third state is a zero-power output state or a no-output state.

[0059] Specifically, in this embodiment, during the current output cycle, each hierarchical high-frequency electrode subarray is in the second state by default. When the high-frequency energy received by the skin region acting on the hierarchical high-frequency electrode subarray reaches the energy required for treatment (a preset high-frequency energy threshold), the hierarchical high-frequency electrode subarray switches to the third state, and remains in the third state for subsequent output cycles. This prevents excessive high-frequency energy from being received by the skin region acting on the hierarchical high-frequency electrode subarray, which could have adverse effects on the human body.

[0060] In one specific embodiment, by precisely controlling the output power and output cycle time of each high-frequency electrode subarray, the high-frequency energy output state of each high-frequency electrode subarray encompasses only two states, a first state and a second state, throughout the treatment cycle, thereby maximizing energy utilization.

[0061] In one specific embodiment, each high-frequency electrode subarray has an output power lower when in the second state than when in the first state. Optionally, each high-frequency electrode subarray has an output power of 40% or less when in the second state than when in the first state.

[0062] In this embodiment, for each high-frequency electrode subarray, increasing the output power increases the output high-frequency energy, while decreasing the output power decreases the output high-frequency energy. In this embodiment, two energy output methods are realized with different output powers, and furthermore, by realizing stepwise treatment of local areas, it is understood that pain can be avoided in the human body.

[0063] In another specific embodiment, for each high-frequency electrode subarray, optionally, the output duty cycle of the high-frequency electrode subarray in the second state is smaller than the output duty cycle of the first state. Optionally, for each high-frequency electrode subarray, the output duty cycle of the second state is 40% or less of the output duty cycle of the first state.

[0064] In this embodiment, within a predetermined unit time, the output duty cycle for each high-frequency electrode subarray refers to the ratio of the effective operating period of the high-frequency electrode subarray within the predetermined unit time to the total period of the predetermined unit time.

[0065] In this embodiment, for each high-frequency electrode subarray, a high output duty cycle results in a longer effective operating period for the high-frequency electrode subarray within the current output cycle. This indicates that the energy of the high-frequency signal output by the high-frequency electrode subarray is stably maintained for a longer period, thereby generating more high-frequency energy. A low output duty cycle results in a shorter effective operating period for the high-frequency electrode subarray within the current output cycle. This indicates that the energy of the high-frequency signal output by the high-frequency electrode subarray is transmitted in a short time, generating a small amount of high-frequency energy. In other words, increasing the output duty cycle increases the output high-frequency energy, and decreasing the output duty cycle decreases the output high-frequency energy. In this embodiment, it is understood that by realizing two energy output methods with different output duty cycles and further enabling stepwise treatment of local areas, it is possible to avoid causing pain to the human body.

[0066] Preferably, the control module 30 includes a first control unit, an output statistics unit, and a second control unit.

[0067] The first control unit is used to control the target high-frequency electrode subarray corresponding to the current output cycle so that it switches to a first state and outputs high-frequency energy in the current output cycle, to control the hysteresis high-frequency electrode subarray so that it is in a second or third state, and to control at least a portion of the remaining high-frequency electrode subarrays of the high-frequency electrode array 50 so that it is in a second state.

[0068] The output statistics unit is used to statistically calculate the cumulative high-frequency energy output by each high-frequency electrode subarray from the first historical output cycle to the present time.

[0069] The second control unit is used to control each high-frequency electrode subarray so that it remains in a no-power-output state when the cumulative high-frequency energy value exceeds a preset high-frequency energy threshold.

[0070] Specifically, the first control unit is used to control the target high-frequency electrode subarray corresponding to the current output period so as to switch to the first state and output high-frequency energy, to control at least a portion of the remaining high-frequency electrode subarrays of the high-frequency electrode array 50 so as to be in the second state when the current output period is the initial output period, and to control the hysteresis high-frequency electrode subarray so as to be in the second or third state when the current output period is a new output period, and to control at least a portion of the remaining high-frequency electrode subarrays of the high-frequency electrode array 50 other than the target high-frequency electrode subarray and the hysteresis high-frequency electrode subarray corresponding to the current output period so as to be in the second state.

[0071] The historical output period refers to the initial output period and the new output period. In this embodiment, for each high-frequency electrode subarray, the cumulative value of high-frequency energy output by each high-frequency electrode subarray from the first historical output period to the present time is statistically calculated, and the high-frequency electrode subarray is controlled to switch to a no-power output state based on a preset high-frequency energy threshold. This solves the problem of excessive high-frequency energy being output to the same skin area of ​​the human body, causing pain to the human body.

[0072] In one specific embodiment, the first control unit includes a temperature parameter acquisition subunit and an output power adjustment subunit.

[0073] The temperature parameter acquisition subunit is used to acquire real-time temperature parameters collected by the temperature sensor.

[0074] The output power adjustment subunit is used to adjust the real-time output power of the target high-frequency electrode subarray corresponding to the current output cycle, based on real-time temperature parameters.

[0075] Furthermore, if the target high-frequency electrode subarray corresponding to the current output cycle outputs high-frequency energy at a fixed power, the temperature of the skin area it acts on will increase, and when the temperature of the human body's skin rises, pain will occur. Based on this, as one specific embodiment, the output power adjustment subunit specifically controls the target high-frequency electrode subarray corresponding to the current output cycle so that, when the real-time temperature parameter is smaller than a preset temperature threshold, the high-frequency energy output subunit outputs high-frequency energy at a preset power. Here, the real-time temperature parameter is the temperature parameter of the skin area on which the target high-frequency electrode subarray corresponding to the current output cycle acts. If the real-time temperature parameter is greater than or equal to a preset temperature threshold, the real-time output power of the target high-frequency electrode subarray corresponding to the current output cycle is adjusted, and the high-frequency energy output subunit controls the target high-frequency electrode subarray corresponding to the current output cycle so that it outputs high-frequency energy at the real-time output power, thereby keeping the temperature of the skin area on which the target high-frequency electrode subarray corresponding to the current output cycle acts below the preset temperature threshold. Here, the real-time output power is used to mean a power lower than the preset power.

[0076] In this embodiment, real-time temperature parameters collected by a temperature sensor are acquired, and the temperature of the skin area on which the target high-frequency electrode subarray acts is controlled to be below a preset temperature threshold. This ensures that even when the target high-frequency electrode subarray outputs high-frequency energy in the first state, the temperature of the skin area on which it acts rises and is maintained thereafter, thereby avoiding causing pain to the human body.

[0077] In this embodiment, in the process of delivering high-frequency energy to the deep layers of the skin using high-frequency electrodes, the instantaneous treatment area at each moment is reduced by treating each local area of ​​the entire treatment area in stages, thereby reducing instantaneous pain. Furthermore, in this application, at least a portion of the high-frequency electrode subarray may output high-frequency energy in both the first and second states. Energy accumulation due to low-power energy output in the second state partially shortens the time required to output high-power high-frequency energy in the first state alone until the energy necessary to achieve treatment is obtained, thereby shortening the total treatment time. This solves the problem that, when the total output power is the same, if the target of the high-frequency energy output at each moment is the entire treatment area, the treatment time becomes longer and the body is more likely to experience pain. Moreover, throughout the treatment process, the low-frequency energy output by the high-frequency electrode subarray in the second state at low power or by other means generates dissipative heat in the treatment area, improving the uniformity of treatment and expanding the treatment area without increasing the sensation of pain, thereby enhancing the treatment effect.

[0078] Based on the same inventive concept, as shown in Figure 2, in a second aspect, the present application also provides an embodiment of a high-frequency therapeutic device, the high-frequency therapeutic device comprising a high-frequency power supply 40, a high-frequency electrode array 50, and a high-frequency electrode array control device as described in the first aspect.

[0079] In this application, the radiofrequency therapy device may be either a non-invasive radiofrequency therapy device or a radiofrequency microneedle therapy device. Of these, a non-invasive radiofrequency therapy device can emit radiofrequency energy simply by attaching radiofrequency electrodes to the surface of the skin, and does not require inserting structures such as microneedles into the epidermis of the skin. On the other hand, a radiofrequency microneedle therapy device is equipped with a radiofrequency microneedle array, and in the treatment process, it is necessary to insert the radiofrequency microneedle array into the epidermis of the skin and advance to the deep tissues of the skin such as the dermis, subcutaneous fat layer, or SMAS layer to emit radiofrequency energy.

[0080] In one specific embodiment, the high-frequency power supply 40 includes a plurality of individually controllable sub-high-frequency power supplies, each used to control a target high-frequency electrode subarray corresponding to a different output period. In each output period, the target high-frequency electrode subarray corresponding to that output period is connected to the sub-high-frequency power supply corresponding to the current output period, thereby supplying energy to the target high-frequency electrode subarray.

[0081] Furthermore, each target high-frequency electrode subarray that simultaneously outputs high-frequency energy is supplied with energy by an individual high-frequency power supply 40, and in this way, the effectiveness and safety of the high-frequency therapy device can be improved.

[0082] As one specific embodiment, the radiofrequency therapy device includes a unipolar mode in which all radiofrequency electrodes contained within a single radiofrequency electrode subarray have the same polarity.

[0083] In another specific embodiment, the radiofrequency therapy device includes a bipolar mode, in which a single radiofrequency electrode subarray includes at least two radiofrequency electrodes with opposite polarities.

[0084] It is understood that selecting the appropriate operating mode according to the patient's specific condition and treatment needs can lead to higher therapeutic effects.

[0085] For further understanding, the following will provide a more detailed explanation with specific examples.

[0086] Figure 3 shows a schematic diagram of the structure of the high-frequency electrode array 50 in unipolar mode. In Figure 3, (a) is a schematic diagram of the structure of the high-frequency electrode array 50 before it is started up, and (b), (c), and (d) are schematic diagrams of the structure of the high-frequency electrode array 50 during the first, second, and third output cycles, respectively.

[0087] As shown in Figure 3, the high-frequency electrode array 50 includes 25 high-frequency electrode subarrays. In unipolar mode, each high-frequency electrode subarray contains one high-frequency electrode. For ease of explanation, each high-frequency electrode subarray is named by its row and column coordinates, and the names of each high-frequency electrode subarray are shown in Figure 3, from (1,1) to (5,5). This high-frequency electrode array 50, consisting of 25 high-frequency electrode subarrays, requires 25 output period traverses.

[0088] In the treatment process, in the unipolar mode of this embodiment, a common electrode with opposite polarity to the radiofrequency electrode array 50 is attached to a part of the human body other than the treatment area. A conductive channel is created between the radiofrequency electrode array 50 and the common electrode so that the radiofrequency electrode array 50 can deliver radiofrequency energy to the deep tissues of the skin, such as the dermis and subcutaneous fat layer. The power of the radiofrequency electrode array 50 is turned on, and radiofrequency energy is radiated by each radiofrequency electrode subarray, generating a radiofrequency current in the deep tissues of the skin and heating the tissue. This promotes the contraction and degeneration of collagen, initiating the regeneration and reconstruction of collagen, repairing, reforming, and tightening the skin. In the form where the radiofrequency electrodes are radiofrequency microneedles, after the radiofrequency discharge is completed, the radiofrequency microneedle array is removed from the skin. The insertion of the microneedles temporarily opens fast-absorbing channels in the skin, so that the repair product applied to the skin can penetrate the skin through these fast-absorbing channels, resulting in a better restorative effect.

[0089] Next, we will describe in detail an important step of traversing the high-frequency electrode array 50 of this embodiment once.

[0090] When the device is started, as shown in Figure 3(b), the first subarray determination module 10 determines the target high-frequency electrode subarray (1,2) corresponding to the initial output period from the high-frequency electrode array 50, and this target high-frequency electrode subarray (1,2) is represented by a slash in Figure 3(b). The control module 30 controls the target high-frequency electrode subarray (1,2) corresponding to the current output period (in this case, the initial output period / the first output period) so that it switches to the first state and outputs high-frequency energy, and controls the other 24 high-frequency electrode subarrays so that the target high-frequency electrode subarray (1,2) maintains the first state and outputs high-frequency energy in the current output period, and also controls the other 24 high-frequency electrode subarrays so that they are in the second state.

[0091] Before entering the second output cycle, the second subarray determination module 20 sets the target high-frequency electrode subarray (1,2) as the hysteresis high-frequency electrode subarray, which is represented by a backslash in Figure 3(c). The second subarray determination module 20 then determines the target high-frequency electrode subarray (4,3) corresponding to the new output cycle (second output cycle) from among the remaining high-frequency electrode subarrays of the high-frequency electrode array 50, excluding the hysteresis high-frequency electrode subarray, which is represented by a slash in Figure 3(c).

[0092] Next, when the initial output cycle ends and the second output cycle begins, the control module 30 controls the target high-frequency electrode subarray (4,3) to switch to the first state and output high-frequency energy, and controls the remaining high-frequency electrode subarray to remain in the second state.

[0093] Before entering the third output cycle, the second subarray determination module 20 sets the target high-frequency electrode subarray (4,3) as the hysteresis high-frequency electrode subarray, and from the remaining high-frequency electrode subarrays of the high-frequency electrode array 50, excluding all of the hysteresis high-frequency electrode subarrays ((1,2) and (4,3), which are represented by backslashes in Figure 3(d)), it determines the target high-frequency electrode subarray (2,4) corresponding to the new output cycle (the third output cycle). This target high-frequency electrode subarray (2,4) is represented by a slash in Figure 3(d).

[0094] Next, when the second output cycle ends and the third output cycle begins, the control module 30 controls the target high-frequency electrode subarray (2,4) to switch to the first state and output high-frequency energy, and controls the remaining high-frequency electrode subarray to remain in the second state.

[0095] Subsequently, the second subarray determination module 20, using the target high-frequency electrode subarray as the hysteresis high-frequency electrode subarray, loops through determining the target high-frequency electrode subarray corresponding to the new output period from among the remaining high-frequency electrode subarrays in the high-frequency electrode array 50, excluding all of the hysteresis high-frequency electrode subarrays, until all of the high-frequency electrode subarrays in the high-frequency electrode array 50 have become hysteresis high-frequency electrode subarrays. In this way, one traverse is completed.

[0096] In a single radiofrequency treatment, it is usually sufficient to traverse the radiofrequency electrode array 50 once within a single tissue region. However, in some cases, the radiofrequency electrode array 50 may be traversed multiple times within a single tissue region. In the latter case, all hierarchical radiofrequency electrode subarrays must be cleared and refreshed after each traverse.

[0097] In the embodiment shown in Figure 3, the target high-frequency electrode subarrays in two adjacent output cycles are not spatially adjacent; specifically, this function is performed by the subarray selection unit described above.

[0098] In one modified embodiment of the example shown in Figure 3, the difference is that, in the current output cycle, if the target high-frequency electrode subarray is held to output high-frequency energy in the first state, only a portion of the remaining high-frequency electrode subarrays, rather than all of them, is controlled to bring it to the second state. For example, in the initial output cycle shown in Figure 3(b), the target high-frequency electrode subarray (1,2) is controlled to be in the first state, while a portion of the remaining 24 high-frequency electrode subarrays is controlled to be in the second state. In the second output cycle shown in Figure 3(c), the target high-frequency electrode subarray (4,3) is controlled to be in the first state, while a portion of the remaining 24 high-frequency electrode subarrays is controlled to be in the second state.

[0099] In another modified embodiment of the embodiment shown in Figure 3, in the current output cycle, if there is a next output cycle relative to the current output cycle, the control module 30 controls the target high-frequency electrode subarray corresponding to the current output cycle to switch to a first state and output high-frequency energy, and in addition to the target high-frequency electrode subarray maintaining the first state and outputting high-frequency energy in the current output cycle, it also controls the target high-frequency electrode subarray corresponding to the next output cycle of the current output cycle to be in a second state. Thus, this modified embodiment is one of the special forms of the above modified embodiment. Taking Figure 3 as an example, in the initial output cycle shown in Figure 3(b), the target high-frequency electrode subarray (1,2) is controlled to be in the first state, and the target high-frequency electrode subarray (4,3) in the second output cycle is controlled to be in the second state, and in the second output cycle shown in Figure 3(c), the target high-frequency electrode subarray (4,3) in the current output cycle is controlled to be in the first state, and the target high-frequency electrode subarray (2,4) in the third output cycle is controlled to be in the second state. In the current output cycle, the remaining high-frequency electrode subarrays, other than those in the first or second state, may be in the third state, a zero-power output state, or a no-output state.

[0100] Figure 4 shows a schematic diagram of the structure of the high-frequency electrode array 50 in bipolar mode. As in Figure 3 and other modified embodiments, the target high-frequency electrode subarray is represented by a slash, the hysteresis high-frequency electrode subarray is represented by a backslash, and the remaining high-frequency electrode subarrays are represented by spaces. In Figure 4, (a) is a schematic diagram of the structure of the high-frequency electrode array 50 before activation, and (b), (c), and (d) are schematic diagrams of the structure of the high-frequency electrode array 50 during the first, second, and third output cycles, respectively.

[0101] The high-frequency electrode array 50 in unipolar mode shown in the embodiment and its modified embodiment in Figure 3 differs mainly in the following points. In the high-frequency electrode array 50 in bipolar mode shown in Figure 4, there are at least two high-frequency electrodes included in the target high-frequency electrode subarray, and these two high-frequency electrodes have different electrode properties (not shown), that is, one is positive and the other is negative, thereby forming a high-frequency current channel in the deep tissue of the skin between the positive electrode and the negative electrode, applying effects such as heating to the tissue and performing treatment.

[0102] Furthermore, in the embodiment shown in Figure 4, the number of electrodes included in the target high-frequency electrode subarray is not necessarily the same for different output periods. For example, in Figure 4, the target high-frequency electrode subarray in both the first and second output periods includes two high-frequency electrodes, while the target high-frequency electrode subarray in the third output period includes three high-frequency electrodes (either two positive electrodes and one negative electrode, or two negative electrodes and one positive electrode).

[0103] The foregoing are merely preferred embodiments of the present application and do not limit the scope of the patent. Any equivalent structure or flow modification, or any other application directly or indirectly to the relevant technical field, utilizing the contents of the specification and accompanying drawings of the present application is also included within the scope of the patent protection of the present application.
