Description

Technical Field

[0001] This application claims the priority of the Chinese patent application with the application number 202410700787.6 filed on May 31, 2024, and all of its contents are incorporated herein by reference.

[0002] This application relates to the technical field of aesthetic medicine, and particularly to a high-frequency electrode array control device and a high-frequency treatment instrument.

Background Art

[0003] The high-frequency electrode array is a skin treatment technology that uses high-frequency technology to treat the skin through the electrode array. Throughout the entire process of the action of the high-frequency electrode, the pain experienced by the human body mainly stems from the process of the high-frequency electrode releasing high-frequency energy rather than the process of the high-frequency electrode piercing the skin. The existence of this pain is one of the most important factors affecting the user experience. Among them, the pain generated during the process of the high-frequency electrode releasing high-frequency energy is positively correlated with factors such as the action time, the action area at the same time, and the power of the high-frequency energy.

[0004] High-frequency electrode arrays are classified into minimally invasive and non-invasive types depending on whether the physical structure is inserted into the skin. Minimally invasive high-frequency electrode arrays include high-frequency microneedle arrays. In conventional high-frequency microneedle array technology, the microneedles act as electrodes. After insertion into the skin, voltage is applied to all high-frequency electrodes in the entire high-frequency microneedle array at the same time, and high-frequency discharge is performed on the entire target skin area until the effect is complete. In this treatment method, the area of ​​action at the same time covers the entire size of the high-frequency electrode array. To achieve the treatment objective, the total power of the high-frequency must be affected, and the action time must be extended to allow the skin tissue to accumulate the received high-frequency energy, increasing the treatment time and intensifying the user's pain. In the case of non-invasive high-frequency electrode arrays, there is no pain from the insertion of microneedles into the skin. However, to achieve the treatment effect, non-invasive high-frequency electrode arrays output high-frequency energy at a higher power. Even in the conventional output mode, the above-mentioned treatment time is increased, and the pain is also intensified.

[0005] Therefore, assuming the total output power is the same, the area of ​​action of the high-frequency electrode array in related technologies at any given time is the entire target skin region, resulting in a large instantaneous area of ​​action and a long overall action time, which increases the user's pain overall. Here, high-frequency energy can generate pulse energy of 1000 Hz or higher. [Overview of the project] [Problems that the invention aims to solve]

[0006] The main objective of this application is to provide a high-frequency electrode array control device and a high-frequency therapeutic device in order to solve the technical problems in related technologies, such as the large instantaneous area of ​​action and long overall action time present in the high-frequency electrode array.

[0014] In one possible embodiment of the present invention, during any overlapping time period, the high-frequency electrode subarrays that are simultaneously in the output cycle are not in adjacent spatial positions.

[0015] In one possible embodiment of the present application, the second subarray determination submodule is specifically: This is used to randomly select a new target high-frequency electrode subarray from among the remaining high-frequency electrode subarrays, excluding all target high-frequency electrode subarrays, and to store the new target high-frequency electrode subarray in the initial sequence.

The control module is It is also used to control each high-frequency electrode subarray so that it remains in a state of no power output when the cumulative high-frequency energy value of the high-frequency electrode subarray exceeds a preset high-frequency energy threshold.

Advantages of the Invention

[0024] One or more of the technical solutions according to the present application can have the following advantages or can at least achieve the following technical effects.

[0025] A high-frequency electrode array control device and a high-frequency therapeutic apparatus according to the present application, the device includes a sub-array determination module and a control module. The sub-array determination module generates a target sequence based on a plurality of high-frequency electrode sub-arrays of the high-frequency electrode array, and the control module controls each high-frequency electrode sub-array in the target sequence to output high-frequency energy in sequence. In the process of transmitting high-frequency energy to the skin action area using the high-frequency electrodes, the action area corresponding to each high-frequency electrode sub-array is a local area of the entire treatment area. By treating each local area step by step, the instantaneous treatment area at each moment is reduced, and the pain in the local area is relieved. Also, the control module controls the (N + n)-th sub-array to output high-frequency energy within the overlapping time period corresponding to the output cycle of the N-th sub-array, so that there is a period of partial overlap between the activation timings in the target sequence corresponding to the output cycles of two adjacent high-frequency electrode sub-arrays. Since there is a treatment gap during the operation of the high-frequency electrode array, the overall action time is prevented from becoming long. And when the total number of high-frequency electrodes in the high-frequency electrode array is large, the overall action time is shortened by the energy accumulation in the overlapping time period, thereby further reducing the pain of the user.

However, it is obvious that the described embodiments are only part of the embodiments of this application, not all embodiments.

[0032] In related technologies, radiofrequency electrode arrays are divided into minimally invasive and non-invasive radiofrequency electrode arrays. Minimally invasive radiofrequency electrode arrays include radiofrequency microneedle arrays and belong to the category of minimally invasive technology. By inserting fine radiofrequency microneedles into the epidermal or dermal layer of the skin, radiofrequency energy is accurately transmitted to the deep layers of the skin using the radiofrequency microneedles. The heating of skin tissue by radiofrequency energy stimulates collagen regeneration and dermal layer regeneration, achieving various effects such as skin regeneration, pore tightening, and reduction of fine lines.

[0033] Analysis of related technologies revealed that high-frequency electrode arrays have problems such as a large instantaneous area of ​​action and a long overall duration of action, resulting in strong pain and a poor user experience. In view of the above technical challenges, this application provides a high-frequency electrode array control device and a high-frequency therapeutic device.

[0034] The high-frequency electrode array control device and high-frequency therapeutic device according to this application will be described in detail below with reference to the attached drawings, along with specific examples and embodiments.

[0035] Example 1 Referring to Figure 1, an embodiment of the high-frequency electrode array control device of the present invention is proposed, which may be a virtual device used in a high-frequency therapeutic device, the high-frequency therapeutic device includes a high-frequency electrode array, and the high-frequency electrode array includes a plurality of high-frequency electrode subarrays, each containing at least one high-frequency electrode.

[0036] As an example, Figure 2 is a schematic diagram of a high-frequency electrode array, where A, B, and C represent three high-frequency electrode subarrays, respectively. A high-frequency electrode array generally includes a series of interconnected, minute, and regularly arranged high-frequency electrodes, typically made of metal, non-insulating material, and / or insulating material. Radiofrequency electrode arrays can be specifically divided into minimally invasive and non-invasive radiofrequency electrode arrays. In the case of minimally invasive radiofrequency electrode arrays, such as radiofrequency microneedle arrays, the metal portion of the radiofrequency electrode is used to transmit radiofrequency energy to the deep layers of the skin. The radiofrequency electrodes are arranged in the form of metal microneedles and can penetrate deep into the skin. Such arranged radiofrequency electrodes can ensure uniform and accurate transmission of radiofrequency energy into the skin during the treatment process, stimulating collagen production and skin regeneration through physical microneedle puncture and radiofrequency energy transmission. In the case of non-invasive radiofrequency electrode arrays, the radiofrequency electrodes are in close contact with the skin surface, and the metal portion of the radiofrequency electrode is used to transmit radiofrequency energy to the skin surface. The radiofrequency electrodes are arranged in the form of metal electrode sheets and can contact the skin surface through a thin film. Such radiofrequency electrodes can ensure uniform and accurate transmission of radiofrequency energy to the skin surface during the treatment process, promoting new cell fiber synthesis and skin tightening and repair through the contact of the metal electrode sheets and radiofrequency energy transmission. The high-frequency electrode array may be installed at different locations on the high-frequency therapy device, and its location depends specifically on the device design. Typically, the high-frequency electrode array is installed at the treatment end of the handle of the high-frequency therapy device.

[0037] For each high-frequency electrode subarray, the polarity of each included high-frequency electrode may or may not be exactly the same, and the polarity of each high-frequency electrode can be specifically set according to the actual situation.

[0038] As shown in Figure 1, this is a schematic diagram of the functional module of the high-frequency electrode array control device. The high-frequency electrode array control device may include a sub-array determination module and a control module. The high-frequency electrode array control device according to this embodiment will be described in detail below, along with the schematic diagram of the functional module shown in Figure 1.

[0039] The subarray determination module is used to generate a target sequence based on a high-frequency electrode array, the target sequence including at least the Nth subarray and the N+nth subarray, whose activation timings are preceding and succeeding each other, where N and n are both positive integers.

[0040] In this embodiment, the parties involved can divide all the high-frequency electrodes included in the high-frequency electrode array either in advance or in real time to obtain multiple high-frequency electrode subarrays, and further generate a target sequence. In one specific embodiment, when determining the high-frequency electrode subarrays, in order to quickly obtain multiple high-frequency electrode subarrays, each high-frequency electrode included in the high-frequency electrode subarray is spatially adjacent. In this embodiment, n=1, and the Nth subarray and the N+nth subarray are any high-frequency electrode subarrays whose activation timing in the target sequence is adjacent.

[0041] In one specific embodiment, the subarray determination module includes a first subarray determination submodule, a second subarray determination submodule, and a target sequence generation submodule, which will be described in detail below.

[0042] The first sub-array determination submodule determines which high-frequency electrode sub-array will first output high-frequency energy after the high-frequency electrode array is activated (i.e., the first high-frequency electrode sub-array to be activated) from among the high-frequency electrode arrays, and stores it in the initial sequence as the target high-frequency electrode sub-array.

[0043] Before executing the first sub-array determination submodule, the initial sequence is empty, meaning it contains no elements, and therefore has a length of zero. The first element in the initial sequence is determined to be the target high-frequency electrode sub-array, which is the first element in the initial sequence, from among the high-frequency electrode arrays to output high-frequency energy after the high-frequency electrode array is activated.

[0044] When determining which high-frequency electrode subarray will first output high-frequency energy after the high-frequency electrode array is activated, all high-frequency electrode subarrays are selectable; that is, any of them are selectable high-frequency electrode subarrays. In this embodiment, the high-frequency electrode subarray that will first output high-frequency energy after the high-frequency electrode array is activated is determined from the high-frequency electrode array by a random selection method. Of course, the first subarray determination submodule may further determine which high-frequency electrode subarray will first output high-frequency energy after the high-frequency electrode array is activated by other methods, such as a look-up table method, and this application does not limit the method for determining the target high-frequency electrode subarray.

[0045] The second sub-array determination submodule is used to determine a new target high-frequency electrode sub-array from the remaining high-frequency electrode sub-arrays, excluding all target high-frequency electrode sub-arrays, and to store it in the initial sequence.

[0046] In a single treatment process, the amount of high-frequency energy received by the skin area acting on the high-frequency electrode array should reach a predetermined value. Based on this, when determining the high-frequency electrode sub-array that will subsequently output high-frequency energy, i.e., a new target high-frequency electrode sub-array, it is selected from the remaining high-frequency electrode sub-arrays, excluding all of the hierarchical high-frequency electrode sub-arrays, thereby avoiding excessive high-frequency energy being transmitted to the same skin area and causing adverse effects on the human body.

[0047] The target sequence generation submodule is used to loop through the second subarray determination submodule until all of the high-frequency electrode subarrays in the high-frequency electrode array become target high-frequency electrode subarrays and the target sequence is obtained.

[0048] The second sub-array determination submodule may be directly connected to the first sub-array determination submodule, or it may be automatically executed after the first sub-array determination submodule has performed its operation and may be executed in a loop, or it may be connected to a control module and controlled by the control module, which controls the first sub-array determination submodule and the second sub-array determination submodule respectively, executing the second sub-array determination submodule after the first sub-array determination submodule has been executed and the second sub-array determination submodule may be executed in a loop.

[0049] In this embodiment, the first sub-array determination submodule acquires the first high-frequency electrode sub-array that outputs high-frequency energy after the high-frequency electrode array is activated, i.e., the target high-frequency electrode sub-array. Then, the second sub-array determination submodule determines the second high-frequency electrode sub-array that outputs high-frequency energy after the high-frequency electrode array is activated, i.e., a new target high-frequency electrode sub-array. The target sequence generation submodule then loops through multiple target high-frequency electrode sub-arrays, ensuring that all high-frequency electrode sub-arrays in the high-frequency electrode array become target high-frequency electrode sub-arrays, thereby controlling the second sub-array determination submodule to loop until the target sequence is obtained.

[0050] In one specific embodiment, the Nth subarray and the N+1th subarray are any adjacent high-frequency electrode subarrays with adjacent activation timings in the target sequence, and the Nth subarray and the N+1th subarray are not adjacent in spatial position.

[0051] Accordingly, the second sub-array determination submodule is used to determine a screening sub-array set from the remaining high-frequency electrode sub-arrays of the high-frequency electrode array, excluding all target high-frequency electrode sub-arrays, to determine a new target high-frequency electrode sub-array based on the screening sub-array set, and to store this new target high-frequency electrode sub-array in the initial sequence, wherein the screening sub-array set does not include any high-frequency electrode sub-arrays whose spatial position is adjacent to the last target high-frequency electrode sub-array in the current initial sequence. As a result of this method, for any Nth and N+1th sub-arrays whose activation timings are adjacent, these two sets of sub-arrays are not spatially adjacent.

[0052] The high-frequency energy output by each high-frequency electrode subarray acts only on a portion of the skin area requiring treatment. By selecting all high-frequency electrode subarrays from the remaining high-frequency electrode subarrays (excluding all target high-frequency electrode subarrays) that are not adjacent to the last target high-frequency electrode subarray in the current initial sequence, and then selecting a new target high-frequency electrode subarray from these remaining subarrays that are not adjacent to the last target high-frequency electrode subarray in the current initial sequence, it is possible to avoid obvious pain in the local skin because the skin areas acted upon by the two high-frequency electrode subarrays that output high-frequency energy one after the other are close together.

[0053] In another specific embodiment, the second subarray determination submodule is used to randomly select a high-frequency electrode subarray from the remaining high-frequency electrode subarrays other than all target high-frequency electrode subarrays of the high-frequency electrode array as a new target high-frequency electrode subarray, and to store the new target high-frequency electrode subarray in the initial sequence.

[0054] The period required to traverse and activate all high-frequency electrode subarrays in a target sequence and complete one output cycle can be considered one large cycle. Different large cycles can correspond to different target sequences, meaning that the activation order of the high-frequency electrode subarrays (the order in which high-frequency energy is output) in each target sequence may differ. Therefore, when the second subarray determination submodule determines a new target high-frequency electrode subarray, it can randomly select from other electrode subarrays, thereby generating different target sequences. In this application, it is possible to control the system to perform only one large cycle of treatment on the same target treatment area, or to perform more than one large cycle of treatment.

[0055] After obtaining the determined target high-frequency electrode subarray, the target high-frequency electrode subarray whose high-frequency energy output sequence follows the last high-frequency electrode subarray in the current initial sequence may be randomly generated, as long as it is ensured that the high-frequency energy delivered to the same skin area is neither too much nor too little. In embodiments of this method, the high-frequency output sequence of the high-frequency electrode subarrays, i.e., the activation timing, may differ in different target sequences.

[0056] Regardless of which specific embodiment the second subarray determination submodule selects, the target sequences obtained by the target sequence generation submodule must all adhere to a certain activation timing, namely, the first element in the target sequence is a high-frequency electrode subarray that outputs high-frequency energy first after the high-frequency electrode array is activated, and the last element is a high-frequency electrode subarray that outputs high-frequency energy last after the high-frequency electrode array is activated.

[0057] The first sub-array determination submodule determines the target high-frequency electrode sub-array that will first output high-frequency energy after the high-frequency electrode array is activated. The target sequence generation submodule then determines target high-frequency electrode sub-arrays corresponding to multiple output periods by iterating directly based on other high-frequency electrode sub-arrays in the high-frequency electrode array, ultimately ensuring that each high-frequency electrode sub-array outputs high-frequency energy during its corresponding output period. Of course, during the actual operation of the high-frequency electrode array, the target sequence generation submodule determines the high-frequency electrode sub-arrays whose output period overlaps with the output period of the currently outputting high-frequency electrode sub-array before the output period corresponding to the currently outputting high-frequency electrode sub-array begins or before the start of the overlapping time period corresponding to that output period. That is, it determines the N+1 sub-array before the output period of the Nth sub-array begins or before the corresponding overlapping time period, thereby obtaining multiple target high-frequency electrode sub-arrays and generating a target sequence. The output period of a high-frequency electrode subarray refers to the time period within one large period during which the high-frequency electrode subarray outputs high-frequency energy. The overlapping time period corresponding to the output period of the Nth subarray refers to the time period during which the output period of the Nth subarray overlaps with the output period of the N+1th subarray.

[0058] In this embodiment, all target high-frequency electrode subarrays are determined based on the target sequence generation submodule, and high-frequency energy is output to each high-frequency electrode subarray at its corresponding output period, thereby completing treatment of all areas included in the skin region and achieving the therapeutic objective.

[0059] The following provides a detailed explanation of the high-frequency electrode array control device according to this embodiment, along with the schematic diagram of the functional module shown in Figure 1.

[0060] The control module is used to control each high-frequency electrode subarray in the target sequence to output high-frequency energy sequentially, and to control the N+nth subarray to output high-frequency energy within an overlapping time period corresponding to the output period of the Nth subarray.

[0061] In other words, the target sequence has at least two high-frequency electrode subarrays whose activation timings are sequential, and these subarrays share a common overlapping time period during which they output high-frequency energy. According to the activation timing, these two high-frequency electrode subarrays are the Nth and N+nth subarrays, respectively, where N and n are both positive integers.

[0062] The following describes in detail an embodiment where n=1. Exemplariously, a high-frequency electrode subarray currently outputting high-frequency energy is designated as the first subarray, and a high-frequency electrode subarray located after and adjacent to the first subarray in the target sequence is designated as the second subarray. That is, the first and second subarrays are two high-frequency electrode subarrays with adjacent activation timings. In this case, the control module can control the second subarray to output high-frequency energy within an overlapping time period corresponding to the output cycle of the first subarray.

[0063] There is a sequential order between the output cycles corresponding to each high-frequency electrode subarray, and each output cycle has its own start and end point. For each high-frequency electrode subarray other than the one corresponding to the last target high-frequency electrode subarray in the target sequence, there is a period of overlap between its output cycle and the output cycle of the immediately following high-frequency electrode subarray whose activation timing is adjacent. That is, there is a period of overlap between the output cycle corresponding to the Nth subarray and the output cycle corresponding to the N+1th subarray, and the length and start time of this overlapping period can be set according to actual demand.

[0064] In one embodiment, the Nth subarray and the N+1th subarray are any adjacent high-frequency electrode subarrays whose activation timings in the target sequence are adjacent.

[0065] For multiple high-frequency electrode subarrays in the target sequence, there may be overlapping time periods between some two adjacent high-frequency electrode subarrays whose activation timings overlap, and there may be overlapping time periods between any two adjacent high-frequency electrode subarrays whose activation timings overlap; that is, the Nth subarray and the N+1th subarray are any adjacent high-frequency electrode subarrays in the target sequence whose activation timings overlap. When there is an overlapping time period between any two adjacent high-frequency electrode subarrays whose activation timings overlap, the overall operating time of the high-frequency electrode array can be further reduced.

[0066] In one embodiment, the output period of any given high-frequency electrode subarray is a continuous period within a large period in which all high-frequency electrode subarrays are traversed and activated.

[0067] For example, if the Nth subarray and the (N+1th)th subarray are any adjacent high-frequency electrode subarrays whose activation timing in the target sequence is adjacent, then the predetermined overlap period between the output period corresponding to the high-frequency electrode subarray other than the last target high-frequency electrode subarray in the target sequence (the Nth subarray) and the output period corresponding to the immediately following high-frequency electrode subarray (the (N+1th) subarray) is the overlap time period, the number of such overlap time periods is 1, and the end of this overlap time period is the end of the output period corresponding to this Nth subarray, and the period during which the high-frequency electrode subarray that follows and is adjacent to the said high-frequency electrode subarray in the target sequence (the (N+1th) subarray) outputs high-frequency energy is a continuous period. As a result shown in this embodiment, the output periods of any high-frequency electrode subarrays in the target sequence are all continuous periods, and there is one overlap time period for each of two adjacent high-frequency electrode subarrays whose activation timing is adjacent.

[0068] In one example of this embodiment, the target sequence includes an overlapping time period corresponding to the output period of the Nth subarray and an overlapping time period corresponding to the output period of the N+1th subarray, where N is a positive integer other than 1, and the maximum value of N is less than the total number of high-frequency electrode subarrays in the high-frequency electrode array.

[0069] For example, for each high-frequency electrode subarray in the target sequence other than the last high-frequency electrode subarray, the overlapping time period of its output cycle, corresponding to the output cycle of the adjacent high-frequency electrode subarray immediately following it, may be predetermined as a continuous portion of the output cycle. That is, this overlapping time period may be a predetermined percentage of the output cycle, for example, 30%, 40%, or half a cycle. Selectively, this percentage is 50% or less, so that in any overlapping time period of a large cycle, there are at most two high-frequency electrode subarrays in the output cycle, that is, at most two high-frequency electrode subarrays simultaneously outputting high-frequency energy.

[0070] In a more specific example, the start of the overlapping time period between the output period of the Nth subarray and the output period of the (N+1)th subarray is predetermined to be the midpoint of the output period of the Nth subarray, and the end of the overlapping time period is the end of the output period. As a result of this embodiment, in the target sequence, the output periods of all high-frequency electrode subarrays except the first and last high-frequency electrode subarrays fall within the overlapping time period.

[0071] As shown in Figure 3, this is a schematic time-period diagram of this example, where the overlapping time period is set to a continuous half-period in the output period, and the start of the overlapping time period is the midpoint of the output period. This schematic diagram shows the relationship between the operating time of multiple continuous output period times and the operating time of the high-frequency electrode array. In Figure 3, A, B, and C represent the output periods of three consecutive output periods, i.e., three high-frequency electrode subarrays whose activation timings are adjacent to each other. As can be seen from Figure 3, for each high-frequency electrode subarray in the target sequence except for the last high-frequency electrode subarray, the overlapping time period corresponding to the output period of the high-frequency electrode subarray with the immediate next activation timing is set to a continuous half-period in the output period, and the start of this overlapping time period is the midpoint of the output period. In this case, the output period of each high-frequency electrode subarray in the target sequence except for the first and last high-frequency electrode subarray consists only of the overlapping time period corresponding to the output period of the immediately preceding high-frequency electrode subarray with an adjacent activation timing, and the overlapping time period corresponding to the output period of the immediately following high-frequency electrode subarray with an adjacent activation timing, and these two overlapping time periods are continuous. This method allows each high-frequency electrode subarray to output high-frequency energy for a completely continuous period. When each high-frequency electrode subarray, except for the first and last high-frequency electrode subarrays in the target sequence, outputs high-frequency energy, there are no periods of non-overlapping energy; that is, the output periods of all other high-frequency electrode subarrays are within the overlapping time frame. This method significantly reduces the length of treatment time, i.e., the length of action of the high-frequency electrode arrays, and can reduce overall user pain.

[0072] In another example of this embodiment, the target sequence includes a period in which at least some of the output periods of the high-frequency electrode subarrays output high-frequency energy only the high-frequency electrode subarrays.

[0073] For example, for each high-frequency electrode subarray in the target sequence other than the last high-frequency electrode subarray, the duration of the overlapping time period of its output period, corresponding to the output period of the adjacent high-frequency electrode subarray immediately following it, may be preset to be less than the duration of half a period of that output period. In other words, in this case, the start time of the overlapping time period of the output period of the Nth subarray, corresponding to the output period of the N+1th subarray, may be preset to be the time obtained by subtracting the duration of the overlapping time period from the end time of the output period of the Nth subarray. As a result shown in this embodiment, in the target sequence, there is a period of time that does not overlap with at least some other high-frequency electrode subarrays other than the first and last high-frequency electrode subarrays, i.e., a period in which only those high-frequency electrode subarrays output high-frequency energy.

[0074] As shown in Figure 4, this is a schematic time-period diagram of this example, where the duration of the overlapping time period is set to be shorter than the duration of half a period of the output period, and the start time of the overlapping time period is the time obtained by subtracting the duration of the overlapping time period from the end time of the output period. This gives a schematic relationship between the operating time of multiple consecutive output periods and the operating time of the high-frequency electrode array. In Figure 4, A, B, and C represent the output periods of three consecutive output periods, i.e., three high-frequency electrode subarrays with adjacent activation timings. As can be seen from Figure 4, for each high-frequency electrode subarray in the target sequence except for the last high-frequency electrode subarray, the duration of the overlapping time period corresponding to the output period of the high-frequency electrode subarray at the immediately following activation timing is set to be less than the duration of half a cycle of the output period. In this case, the start time of this overlapping time period is the time obtained by subtracting the duration of the overlapping time period from the end time of the output period. In this case, the output period of each high-frequency electrode subarray in the target sequence except for the first and last high-frequency electrode subarrays consists of an overlapping time period corresponding to the output period of the immediately preceding high-frequency electrode subarray whose activation timing is adjacent, a period in which only that subarray outputs high-frequency energy, and an overlapping time period corresponding to the output period of the immediately following high-frequency electrode subarray whose activation timing is adjacent, and these three time periods are continuous. This method allows each high-frequency electrode subarray to output high-frequency energy for a completely continuous period. When each high-frequency electrode subarray, except for the first and last high-frequency electrode subarrays in the target sequence, outputs high-frequency energy, there are continuous overlapping and non-overlapping periods. During the non-overlapping periods, i.e., within the output cycle of each high-frequency electrode subarray, there is at least one period in which only that high-frequency electrode subarray outputs high-frequency energy. This overlapping method of the high-frequency electrode subarrays reduces the total operating time of the high-frequency electrode arrays and, overall, reduces user discomfort.

[0075] In another embodiment, within a large period that traverses and activates all high-frequency electrode subarrays, the output period of any given high-frequency electrode subarray is a discontinuous period.

[0076] For example, for any high-frequency electrode subarray in the target sequence other than the first high-frequency electrode subarray, the number of time periods corresponding to its output period is at least two, and these at least two time periods are discontinuous; and / or the number of overlapping time periods corresponding to the output period of the adjacent high-frequency electrode subarray whose activation timing is immediately after its output period is one, and the end of the overlapping time period is not the end of the output period of this particular high-frequency electrode subarray, and thus the period during which any high-frequency electrode subarray other than the first and last high-frequency electrode subarrays in the target sequence outputs high-frequency energy is a discontinuous period.

[0077] In one example of this embodiment, within a large period in which all high-frequency electrode subarrays are traversed and activated, the output period of the N+nth subarray includes at least two discontinuous high-frequency energy output periods, and in one specific example, there is a time period that overlaps between the previous high-frequency energy output period and the output period of the Nth subarray, and in another specific example, there is a time period that overlaps between the later high-frequency energy output period and the output period of the Nth subarray.

[0078] N is a positive integer, and the maximum value of N is less than the total number of high-frequency electrode subarrays in the high-frequency electrode array, i.e., the (N+1)th subarray may be the last high-frequency electrode subarray in the target sequence.

[0079] As shown in Figure 5, this is a schematic time-period diagram of this example. When the number is 1 and the overlapping time period is set such that the end time is not the end of the output period of the high-frequency electrode subarray, a schematic relationship diagram is given between the continuous output period time and the operating time of the high-frequency electrode array. In Figure 5, A, B, and C represent three continuous output periods, i.e., the output periods of three high-frequency electrode subarrays whose activation timings are adjacent to each other. As can be seen from Figure 5, by setting an overlapping time period corresponding to the output period for each high-frequency electrode subarray in the target sequence, except for the last high-frequency electrode subarray, such that the number is 1 and the end of the overlapping time period does not coincide with the end of its output period, it is possible to make the time when all high-frequency electrode subarrays (any N+1th subarray) output high-frequency energy completely discontinuous, except for the first subarray that outputs high-frequency energy after the high-frequency electrode array is activated (the first subarray). This means that there is a discontinuous overlapping time period between each high-frequency electrode subarray in the target sequence, except for the first and last high-frequency electrode subarrays, and between the two high-frequency electrode subarrays adjacent to each other in the target sequence in terms of their activation timing. In other words, Figure 5 shows that the output period of any N+1th subarray includes two discontinuous high-frequency energy output periods, with an overlapping time period between the immediately preceding high-frequency energy output period and the output period of the Nth subarray, and an overlapping time period between the immediately following high-frequency energy output period and the output period of the N+1th subarray. This method can similarly reduce the operating time of the high-frequency electrode array and reduce user discomfort overall.

[0080] As can be seen from Figures 3 to 5, within any overlapping time period, the number of high-frequency electrode subarrays in the output period is 2, that is, the number of high-frequency electrode subarrays that output high-frequency energy at any given time is 2.

[0081] By setting overlapping time zones for each high-frequency electrode subarray except for the last target high-frequency electrode subarray in the target sequence, the activation timing in the target sequence overlaps with the period when two adjacent high-frequency electrode subarrays emit high-frequency energy. This avoids the existence of treatment gaps during the operation of the high-frequency electrode arrays (i.e., avoids the existence of a stop period within a large period in which the high-frequency electrode array emits high-frequency energy). Furthermore, if the total number of high-frequency electrodes in the high-frequency electrode array is large, the number of times the high-frequency electrode array is treated in stages can be reduced, thereby shortening the time required to complete one treatment and reducing the overall treatment time. Additionally, by reducing the skin area acted upon at the same time, the patient's sensitivity to high-frequency energy and pain can be reduced.

[0082] Of course, if only the last high-frequency electrode subarray in the target sequence is outputting high-frequency energy, it indicates that the current output cycle is the final output cycle to complete the treatment, and at this time, all remaining high-frequency electrode subarrays other than the last high-frequency electrode subarray in the target sequence have completed their therapeutic action in the skin area they act on.

[0083] Next, we will briefly describe the embodiment of n>1 in this application, along with the description of the embodiment of n=1 described above.

[0084] In such n>1 embodiments, the control module controls the N+nth subarray to output high-frequency energy within an overlapping time period corresponding to the output period of the Nth subarray. That is, in the target sequence generated by the subarray determination module, the Nth and N+nth subarrays, which are not adjacent but have their activation timings one after the other, share a common overlapping time period. Such embodiments can also utilize this overlapping time period to store energy, shorten the overall duration of operation, and reduce user discomfort, as in the n=1 embodiment described above.

[0085] In such embodiments where n>1, if the output periods within the large period of each high-frequency electrode subarray are continuous, then there will always be a common overlapping time period for the N, N+1..., N+nth subarrays. To avoid severe pain due to too many high-frequency electrode subarrays simultaneously present in the output period, it is preferable in this application to set the number of high-frequency electrode subarrays simultaneously present in the output period to be smaller than a preset value, which may be, for example, 3 or 4.

[0086] In such embodiments where n>1, if discontinuous high-frequency electrode subarrays exist within a large output period, there may be high-frequency electrode subarrays between the Nth subarray and the N+nth subarray that do not overlap with the Nth subarray in terms of time period. For example, the output period of the first subarray is divided into two discontinuous high-frequency energy output periods (abbreviated as output time periods), the output period of the second subarray and the output period of the first subarray do not overlap, and at least a portion of these periods lies between the two output time periods of the first subarray, while the output period of the third subarray overlaps with the output time period of the first subarray.

[0087] In such embodiments where n>1, other technical solutions that do not conflict with the n=1 embodiment, such as the functions and structures of the subarray decision module, can be found in the description above and will not be described further here.

[0088] It is important to reiterate that the pain generated by a high-frequency electrode array is closely related to the area over which high-frequency energy is being emitted at the same time. Whether n=1 or n>1, in some embodiments of the present application, a certain high-frequency electrode subarray may have time periods that overlap with one or more other high-frequency electrode subarrays, and regardless of the number of high-frequency electrode subarrays in the overlapping time periods, in any overlapping time period, the high-frequency electrode subarrays that are simultaneously in the output cycle are not spatially adjacent to each other, thus avoiding the occurrence of obvious pain in the local skin.

[0089] Preferably, the high-frequency electrode array control device according to this embodiment further includes an output statistics module. The output statistics module is used to statistically collect the cumulative high-frequency energy output by each high-frequency electrode subarray from the time of initial activation to the present, and the control module is also used to control each high-frequency electrode subarray such that it is in a no-power-output state if the cumulative high-frequency energy value of the high-frequency electrode subarray is greater than or equal to a preset high-frequency energy threshold.

[0090] The hierarchical output period refers to the output period corresponding to the high-frequency electrode subarray that output high-frequency energy. In this embodiment, for each high-frequency electrode subarray, the cumulative value of high-frequency energy output by the high-frequency electrode subarray from the initial activation to the present is statistically calculated, and the high-frequency electrode subarray is controlled to a state of no power output based on a preset high-frequency energy threshold. This prevents the output of too much high-frequency energy to the same skin area of ​​the human body, which could cause pain.

[0091] Preferably, in the high-frequency electrode array control device according to this embodiment, the control module further includes a parameter acquisition unit and an output power adjustment unit.

[0092] The parameter acquisition unit is used to acquire real-time temperature parameters collected by the temperature sensor, and the output power adjustment unit is used to adjust the real-time output power of the high-frequency electrode subarray that currently outputs high-frequency energy, based on the real-time temperature parameters.

[0093] A radiofrequency therapy device may be equipped with one or more temperature sensors to detect temperature changes in the skin surface and deep tissues. Furthermore, if a radiofrequency electrode subarray that outputs radiofrequency energy currently outputs radiofrequency energy at a fixed power, the temperature of the affected skin area will rise, and this rise in skin temperature can cause pain.

[0094] Based on this, as one specific embodiment, the output power adjustment unit is used to cause a control module to control a high-frequency electrode subarray that is currently outputting high-frequency energy so that it outputs high-frequency energy at a preset power when the real-time temperature parameter is less than a preset temperature threshold, where the real-time temperature parameter is the temperature parameter of the skin region on which the high-frequency electrode subarray that is currently outputting high-frequency energy acts, and when the real-time temperature parameter is greater than or equal to a preset temperature threshold, the unit adjusts the output power of the high-frequency electrode subarray that is currently outputting high-frequency energy and causes the control module to control the high-frequency electrode subarray so that it outputs high-frequency energy at the adjusted output power, thereby keeping the temperature of the skin region on which the high-frequency electrode subarray that is currently outputting high-frequency energy acts below the preset temperature threshold, where the real-time output power is used to mean a power lower than the preset power.

[0095] In this embodiment, real-time temperature parameters collected by a temperature sensor are acquired, and the temperature of the skin area on which the high-frequency electrode subarray that currently outputs high-frequency energy acts is controlled to be below a preset temperature threshold. As a result, even when the high-frequency electrode subarray outputs high-frequency energy, the temperature of the skin area on which it acts rises and then remains stable, thereby preventing pain from being caused in the human body.

[0096] Preferably, the high-frequency electrode subarray includes at least two high-frequency electrodes that are not adjacent to each other.

[0097] For example, if the three high-frequency electrodes in A and the two high-frequency electrodes in B of Figure 2 are determined as the first subarray of the target sequence, then subsequent control of this first subarray is actually simultaneous control of these five high-frequency electrodes, and multiple high-frequency electrodes that are not spatially adjacent are considered as a single whole as one high-frequency electrode subarray at a certain activation timing in the target sequence. By determining multiple high-frequency electrodes that are not spatially adjacent as a single high-frequency electrode subarray, the number of times the process of determining the target high-frequency electrode subarray from the high-frequency electrode array is looped during treatment, i.e., the number of output cycles, can be reduced, thereby shortening the time required to complete one treatment. Furthermore, for the same total treatment area, a total treatment area consisting of multiple non-adjacent treatment areas (i.e., action areas corresponding to high-frequency electrodes) causes less pain to the human body compared to a total treatment area consisting of adjacent treatment areas.

[0098] Preferably, in the high-frequency electrode array control device according to this embodiment, the number of high-frequency electrodes in each high-frequency electrode subarray is equal, or the difference in the number is smaller than a preset threshold, in order to facilitate control of the uniformity of the distribution of therapeutic energy.

[0099] The high-frequency electrode array control device according to this embodiment includes a sub-array determination module and a control module. The sub-array determination module generates a target sequence based on multiple high-frequency electrode sub-arrays of the high-frequency electrode array, and the control module controls each high-frequency electrode sub-array in the target sequence to output high-frequency energy sequentially. In the process of transmitting high-frequency energy to the skin action area using the high-frequency electrodes, the action area corresponding to each high-frequency electrode sub-array is a local area of ​​the entire treatment area. By treating each local area step by step, the instantaneous treatment area at each point in time is reduced, thereby reducing pain in the local area. Furthermore, the control module controls the N+1 sub-array to output high-frequency energy within an overlapping time period corresponding to the output cycle of the Nth sub-array. This avoids a situation where the activation timing in the target sequence overlaps with the output cycles of two adjacent high-frequency electrode sub-arrays, resulting in a treatment gap during the operation of the high-frequency electrode array and thus a longer overall action time. Additionally, when the total number of high-frequency electrodes in the high-frequency electrode array is large, the energy accumulation during the overlapping time periods shortens the overall action time, thereby further reducing user pain.

[0100] When the high-frequency electrode array control device according to this embodiment is used in a high-frequency therapeutic device, the high-frequency therapeutic device includes a high-frequency power supply and a high-frequency electrode array, the high-frequency electrode array is electrically connected to the high-frequency power supply, and the high-frequency electrode array includes a plurality of high-frequency electrode subarrays, each containing at least one high-frequency electrode.

[0101] Specifically, the high-frequency power supply may be a single unit, meaning a single high-frequency power supply powers the high-frequency electrode array; or it may be a multiple high-frequency power supply, each connected to a switch module of the high-frequency therapy device. The switch module is controlled by the control unit of the high-frequency therapy device and is used to regulate the output and transmission of high-frequency energy by enabling conduction and interruption between the high-frequency electrode array and the high-frequency power supply.

[0102] Example 2 Based on the same concept of the invention, the present application further provides a high-frequency therapeutic device with reference to Figure 6. The high-frequency therapeutic device of this embodiment will be described in detail below, along with the schematic diagram of the functional module shown in Figure 6.

[0103] The high-frequency therapeutic device includes a high-frequency power supply, a high-frequency electrode array, and a high-frequency electrode array control device of Example 1, both of which are connected to the high-frequency electrode array.

[0104] In one specific embodiment, the radiofrequency therapy device includes one radiofrequency power supply, and each radiofrequency electrode subarray is connected in parallel to the radiofrequency power supply, and the output power of the radiofrequency power supply remains constant during the overlapping time period.

[0105] If the radiofrequency therapy device includes only one radiofrequency power supply, all radiofrequency electrode subarrays included in the radiofrequency electrode array are powered via the same radiofrequency power supply. In this embodiment, for each radiofrequency electrode subarray other than the last radiofrequency electrode subarray in the target sequence (the Nth subarray), if the period during which the radiofrequency electrode subarray outputs radiofrequency energy coincides with the overlapping time period corresponding to its output cycle, power is allocated in parallel between the radiofrequency electrode subarray and another adjacent radiofrequency electrode subarray (the N+1th subarray) whose activation timing in the target sequence follows.

[0106] Specifically, if the total power output by the high-frequency power supply to each high-frequency electrode subarray in the target sequence, except for the last high-frequency electrode subarray, is a predetermined value, then the high-frequency power supply needs to output power to this Nth subarray and the N+1th subarray. As a result, the average power of this Nth subarray within the overlapping time period corresponding to its output cycle will be smaller than the average power of other periods outside of that overlapping time period in its output cycle. If the total power output by the high-frequency power supply is a variable value, the high-frequency electrode array control device can control the total output power of the high-frequency electrode array to increase within the overlapping time period corresponding to the output cycle of the high-frequency electrode subarray.

[0107] In another specific embodiment, the high-frequency power supply includes a plurality of sub-high-frequency power supplies, each used to control a high-frequency electrode subarray corresponding to a different output period, such that the output power of each high-frequency electrode subarray remains constant.

[0108] If a radiofrequency therapy device includes multiple sub-radiofrequency power supplies, different radiofrequency electrode subarrays may be individually controlled by different sub-radiofrequency power supplies, i.e., individually controlled by their corresponding sub-radiofrequency power supplies. Of course, one sub-radiofrequency power supply may control multiple radiofrequency electrode subarrays. For example, if there are 20 radiofrequency electrode subarrays and 5 sub-radiofrequency power supplies, each sub-radiofrequency power supply can control 4 radiofrequency electrode subarrays. In one specific embodiment, for each radiofrequency electrode subarray other than the last radiofrequency electrode subarray in the target sequence (the Nth subarray), the sub-radiofrequency power supply connected to that subarray is different from the sub-radiofrequency power supply connected to another adjacent radiofrequency electrode subarray (the N+1th subarray) whose activation timing in the target sequence is subsequent, thereby avoiding an average power drop within the overlapping time period corresponding to the output cycle of the radiofrequency electrode subarray and shortening the treatment time.

[0109] In one specific embodiment, the radiofrequency therapy device includes a unipolar mode in which all radiofrequency electrodes included in a single radiofrequency electrode subarray have the same polarity, and the radiofrequency therapy device further includes one electrode plate whose polarity is opposite to that of the radiofrequency electrode array.

[0110] Specifically, when the operating mode of the radiofrequency therapy device is unipolar mode, for each radiofrequency electrode subarray, all the needle electrodes of the included radiofrequency electrodes have the same polarity, and the entire set of non-needle electrodes with different polarities can be attached to locations on the human body such as the back or buttocks.

[0111] 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.

[0112] Specifically, the needle electrodes of a high-frequency electrode can have either a positive or negative polarity. High-frequency electrodes with positive needle electrodes and high-frequency electrodes with negative needle electrodes can jointly constitute a single high-frequency electrode subarray.

[0113] By selecting the appropriate operating mode according to the patient's specific situation and treatment needs, better therapeutic effects can be achieved.

[0114] The above-mentioned embodiments are for illustrative purposes only and do not represent any superiority or inferiority among the embodiments. The above embodiments are merely selective embodiments of the present invention and therefore do not limit the scope of the patent of the present invention.
