Description

Radiofrequency electrode array control device and radiofrequency therapy instrument

[0001] This application claims priority to Chinese patent application No. 202410700787.6, filed on May 31, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of cosmetic medical technology, and in particular to a radio frequency electrode array control device and a radio frequency therapy instrument. Background Technology

[0003] Radiofrequency electrode arrays are a skin treatment technology that uses radiofrequency technology to treat the skin through an electrode array. Throughout the entire process of radiofrequency electrode application, the pain experienced by the patient primarily originates from the release of radiofrequency energy by the electrodes, rather than the insertion of the electrodes into the skin. This pain is one of the most significant factors affecting the user experience. Specifically, the pain generated during the release of radiofrequency energy is positively correlated with factors such as the duration of the treatment, the area treated simultaneously, and the power of the radiofrequency energy.

[0004] Radiofrequency electrode arrays are categorized into minimally invasive and non-invasive types based on whether they physically penetrate the skin. Minimally invasive radiofrequency electrode arrays include radiofrequency microneedle arrays. In traditional radiofrequency microneedle array technology, microneedles act as electrodes. After being inserted into the skin, all radiofrequency electrodes of the entire array are simultaneously charged with voltage, delivering radiofrequency discharge to the entire target skin area until the treatment ends. This treatment method covers the entire size of the radiofrequency electrode array at any given time. To achieve the desired therapeutic effect, the total radiofrequency power necessitates a longer treatment time to accumulate the radiofrequency energy received by the skin tissue, resulting in increased treatment time and greater pain for the user. While non-invasive radiofrequency electrode arrays eliminate the pain of microneedles penetrating the skin, they still require a higher power output to achieve the desired therapeutic effect. Under traditional output modes, they also suffer from the same issues of increased treatment time and greater pain.

[0005] Therefore, under the premise of the same total output power, the area of ​​action of the radio frequency electrode array in the related technology is the entire target skin area at any time. This has the problems of a large instantaneous area of ​​action and a long overall action time, which increases the user's pain overall. Technical issues

[0006] The main objective of this application is to provide a radio frequency electrode array control device and a radio frequency therapy device, which aims to solve the technical problems of large instantaneous action area and long overall action time of radio frequency electrode arrays in related technologies. Technical solutions

[0007] To achieve the above objectives, this application adopts the following technical solution:

[0008] In a first aspect, this application provides a radio frequency electrode array control device for use in a radio frequency therapy device. The radio frequency therapy device includes a radio frequency electrode array, which includes multiple radio frequency electrode subarrays, each of which includes at least one radio frequency electrode. The device includes: a subarray determination module, configured to generate a target sequence based on the radio frequency electrode array, wherein the target sequence includes at least an Nth subarray and an (N+n)th subarray with sequential activation, where N and n are both positive integers; and a control module, configured to control each radio frequency electrode subarray in the target sequence to output radio frequency energy sequentially, and to control the (N+n)th subarray to output radio frequency energy during an overlapping period corresponding to the output period of the Nth subarray.

[0009] In one possible embodiment of this application, the Nth subarray and the (N+n)th subarray are randomly selected radio frequency electrode subarrays with adjacent activation times in the target sequence, where n is 1.

[0010] In one possible embodiment of this application, the output period of any radio frequency electrode subarray is a continuous time period during the large cycle of traversing and activating all radio frequency electrode subarrays.

[0011] In one possible embodiment of this application, in the target sequence, the output cycle of at least a portion of the radio frequency electrode subarray includes a time period in which only the radio frequency electrode subarray outputs radio frequency energy.

[0012] In one possible embodiment of this application, during a large cycle of traversing and activating all RF electrode subarrays, the output cycle of the N+n subarray includes at least two discontinuous RF energy output time periods.

[0013] In one possible embodiment of this application, the subarray determination module includes: a first subarray determination submodule, used to determine the first radio frequency electrode subarray that outputs radio frequency energy after the radio frequency electrode array is started, and store it as a target radio frequency electrode subarray in the initial sequence; a second subarray determination submodule, used to determine a new target radio frequency electrode subarray from the remaining radio frequency electrode subarrays in the radio frequency electrode array other than all target radio frequency electrode subarrays and store it in the initial sequence; and a target sequence generation submodule, used to repeatedly execute the second subarray determination submodule until all radio frequency electrode subarrays in the radio frequency electrode array are target radio frequency electrode subarrays, thereby obtaining a target sequence.

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

[0015] In one possible embodiment of this application, the second subarray determining submodule is specifically used for:

[0016] From the remaining radio frequency electrode subarrays in the radio frequency electrode array excluding all target radio frequency electrode subarrays, a radio frequency electrode subarray is randomly selected as a new target radio frequency electrode subarray, and the new target radio frequency electrode subarray is stored in the initial sequence.

[0017] In one possible embodiment of this application, the apparatus further includes:

[0018] The output statistics module is used to calculate the cumulative radio frequency energy value output by each radio frequency electrode subarray from the first activation time to the current time.

[0019] The control module is also used for:

[0020] For each RF electrode subarray, if the cumulative RF energy value of the RF electrode subarray is greater than or equal to the preset RF energy threshold, the RF electrode subarray is controlled to be in a no-power output state.

[0021] In one possible embodiment of this application, the control module further includes:

[0022] Temperature parameter acquisition unit, used to acquire real-time temperature parameters collected by temperature sensor;

[0023] The output power adjustment unit is used to adjust the real-time output power of the RF electrode subarray that outputs RF energy based on real-time temperature parameters.

[0024] In one possible embodiment of this application, the number of radio frequency electrodes in each radio frequency electrode subarray is equal or the difference in number is less than a preset number threshold.

[0025] Secondly, this application also provides a radiofrequency therapy device, which includes a radiofrequency power supply, a radiofrequency electrode array, and a radiofrequency electrode array control device as described above, wherein the radiofrequency power supply and the radiofrequency electrode array control device are both connected to the radiofrequency electrode array.

[0026] In one possible embodiment of this application, the radiofrequency therapy device includes a radiofrequency power supply, and each radiofrequency electrode subarray is connected in parallel and then connected to the radiofrequency power supply. The output power of the radiofrequency power supply remains unchanged during the overlapping period.

[0027] In one possible embodiment of this application, the radio frequency power supply includes multiple sub-radio frequency power supplies, each of which is used to control radio frequency electrode subarrays corresponding to different output cycles, so that the output power of each radio frequency electrode subarray remains unchanged.

[0028] In one possible embodiment of this application, the radiofrequency therapy device includes a monopolar mode in which all radiofrequency electrodes contained in a single radiofrequency electrode subarray have the same polarity; the radiofrequency therapy device also includes an electrode plate with the opposite polarity to the radiofrequency electrode array.

[0029] In one possible embodiment of this application, the radiofrequency therapy device includes a bipolar mode in which a single radiofrequency electrode subarray includes at least two radiofrequency electrodes of opposite polarity. Beneficial effects

[0030] The above-mentioned one or more technical solutions provided in this application may have the following advantages or at least achieve the following technical effects:

[0031] This application discloses a radiofrequency electrode array control device and a radiofrequency therapy device. The device includes a subarray determination module and a control module. The subarray determination module generates a target sequence based on multiple radiofrequency electrode subarrays of the radiofrequency electrode array. The control module then controls each radiofrequency electrode subarray in the target sequence to output radiofrequency energy sequentially. During the process of delivering radiofrequency energy to the skin's treatment area using radiofrequency electrodes, the treatment area corresponding to each radiofrequency electrode subarray is a local area of ​​the entire treatment area. By treating each local area in a time-sequential manner, the instantaneous treatment area at each moment is reduced, thereby alleviating pain in the local area. Simultaneously, the control module controls the N+n subarray to output radiofrequency energy within the overlapping time period corresponding to the output cycle of the Nth subarray. This ensures that the output cycles of two radiofrequency electrode subarrays with adjacent activation times in the target sequence partially overlap, avoiding treatment gaps in the radiofrequency electrode array's operation that would increase the overall treatment time. Furthermore, when the total number of radiofrequency electrodes in the radiofrequency electrode array is large, the energy accumulation during the overlapping time period can shorten the overall treatment time, thereby further reducing user pain.

[0042] In related technologies, radio frequency electrode arrays are divided into minimally invasive radio frequency electrode arrays and non-invasive radio frequency electrode arrays. Among them, minimally invasive radio frequency electrode arrays include radio frequency microneedle arrays, which belong to the minimally invasive technology. By inserting tiny radio frequency microneedles into the epidermis or dermis of the skin, radio frequency energy is precisely delivered to the deep layers of the skin. The heating of the skin tissue by radio frequency energy stimulates the regeneration of collagen and dermis, achieving multiple effects such as skin rejuvenation, pore tightening, and reduction of fine lines.

[0043] Analysis of related technologies revealed that radiofrequency electrode arrays suffer from a large instantaneous action area and a long overall action time, resulting in strong pain for users and a poor user experience. In view of the above technical problems, this application provides a radiofrequency electrode array control device and a radiofrequency therapy instrument.

[0044] The radio frequency electrode array control device and radio frequency therapy device provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and implementation methods.

[0045] Example 1

[0046] Referring to FIG1, an embodiment of the radio frequency electrode array control device of this application is presented. The radio frequency electrode array control device can be a virtual device and is applied to a radio frequency therapy device. The radio frequency therapy device includes a radio frequency electrode array, which includes multiple radio frequency electrode subarrays, and each radio frequency electrode subarray includes at least one radio frequency electrode.

[0047] For example, Figure 2 shows a schematic diagram of a radio frequency (RF) electrode array, where A, B, and C represent three RF electrode subarrays. The RF electrode array comprises a series of interconnected, tiny RF electrodes arranged according to a certain rule. These RF electrodes are typically composed of metal, non-insulating materials, and / or insulating materials. Radiofrequency electrode arrays can be specifically divided into minimally invasive and non-invasive types. For minimally invasive arrays, such as radiofrequency microneedle arrays, the metal portion of the radiofrequency electrodes is used to deliver radiofrequency energy to the deeper layers of the skin. The electrodes are arranged in the form of metal microneedles, penetrating deep into the skin. This arrangement ensures uniform and precise delivery of radiofrequency energy to the skin during treatment. Through the physical puncture of the microneedles and the delivery of radiofrequency energy, collagen production and skin regeneration are stimulated. For non-invasive arrays, the radiofrequency electrodes are placed close to the skin surface. The metal portion of the electrodes is used to deliver radiofrequency energy to the superficial layer of the skin. The electrodes are arranged in the form of metal electrode pads, contacting the skin surface through a thin film. This type of array ensures uniform and precise delivery of radiofrequency energy to the skin surface during treatment. Through the application of the metal electrode pads and the delivery of radiofrequency energy, new cell fiber synthesis and skin tightening and repair are promoted. It is worth mentioning that the radiofrequency electrode array can be set in different positions on the radiofrequency therapy device, depending on the specific design of the device. Typically, the radiofrequency electrode array is set on the treatment end of the handpiece of the radiofrequency therapy device.

[0048] For each RF electrode subarray, the polarity of each RF electrode may be exactly the same or not exactly the same, and the polarity of each RF electrode may be specifically set according to the actual situation.

[0049] Figure 1 shows a functional module diagram of the radio frequency electrode array control device. The radio frequency electrode array control device may include a subarray determination module and a control module. The radio frequency electrode array control device provided in this embodiment will be described in detail below with reference to the functional module diagram shown in Figure 1.

[0050] The subarray determination module is used to generate a target sequence based on the radio frequency electrode array, wherein the target sequence includes at least the Nth subarray and the (N+n)th subarray with sequential activation, where N and n are both positive integers.

[0051] In this embodiment, relevant personnel can pre-divide all the radio frequency electrodes contained in the radio frequency electrode array, either in advance or in real time, to obtain multiple radio frequency electrode subarrays, and then generate the target sequence. As a specific implementation, when determining the radio frequency electrode subarrays, the spatial positions of the radio frequency electrodes contained in each subarray are adjacent to facilitate the rapid generation of multiple subarrays. In this embodiment, n=1, and the Nth subarray and the (N+n)th subarray are randomly selected radio frequency electrode subarrays with adjacent activation times in the target sequence.

[0052] 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:

[0053] The first subarray determination submodule is used to determine the first radio frequency electrode subarray that outputs radio frequency energy after the radio frequency electrode array is started (i.e., the first activated radio frequency electrode subarray) from the radio frequency electrode array, and store it as the target radio frequency electrode subarray in the initial sequence.

[0054] Before executing the first subarray determination submodule, the initial sequence is empty, that is, there are no elements in the initial sequence, which means the length of the initial sequence is zero. The first radio frequency electrode subarray that outputs radio frequency energy after the radio frequency electrode array is started is determined from the radio frequency electrode array, and the target radio frequency electrode subarray is the first element in the initial sequence.

[0055] When determining the first RF electrode subarray to output RF energy after the RF electrode array is started, all RF electrode subarrays are available for selection; that is, all are candidate RF electrode subarrays. In this embodiment, a random selection method is used to determine the first RF electrode subarray to output RF energy after the RF electrode array is started. Of course, the first subarray determination submodule can also use other methods to determine the first RF electrode subarray to output RF energy after the RF electrode array is started, such as a look-up table. This application does not limit the method for determining the target RF electrode subarray.

[0056] The second subarray determination submodule is used to determine a new target RF electrode subarray from the remaining RF electrode subarrays in the RF electrode array, excluding all target RF electrode subarrays, and store it in the initial sequence.

[0057] During a single treatment, the amount of radiofrequency energy received by the skin area treated by the radiofrequency electrode array needs to reach a certain value. Based on this, when determining the radiofrequency electrode subarray that will output radiofrequency energy later, i.e., the new target radiofrequency electrode subarray, it is selected from the remaining radiofrequency electrode subarrays in the radiofrequency electrode array, excluding all historical radiofrequency electrode subarrays. This can avoid delivering too much radiofrequency energy to the same skin area, which could have adverse effects on the human body.

[0058] The target sequence generation submodule is used to repeatedly execute the second subarray determination submodule until all RF electrode subarrays in the RF electrode array are target RF electrode subarrays, thus obtaining the target sequence.

[0059] The second subarray determination submodule can be directly connected to the first subarray determination submodule, and automatically and cyclically execute after the first subarray determination submodule performs its action; or it can be connected to the control module, and the control module can control the first and second subarray determination submodules respectively, executing the second subarray determination submodule after the first subarray determination submodule is executed, and cyclically executing the second subarray determination submodule.

[0060] In this embodiment, after the first subarray determination submodule obtains the first radio frequency electrode subarray that outputs radio frequency energy after the radio frequency electrode array is started, i.e., the target radio frequency electrode subarray, the second subarray determination submodule determines the second radio frequency electrode subarray that outputs radio frequency energy after the radio frequency electrode array is started, i.e., the new target radio frequency electrode subarray. Then, the target sequence generation submodule controls the second subarray determination submodule to execute cyclically until multiple target radio frequency electrode subarrays are determined cyclically, ensuring that all radio frequency electrode subarrays in the radio frequency electrode array are target radio frequency electrode subarrays, thereby obtaining the target sequence.

[0061] In one specific implementation, the Nth subarray and the N+1th subarray are randomly selected radio frequency electrode subarrays with adjacent activation times in the target sequence; the Nth subarray and the N+1th subarray are not spatially adjacent.

[0062] Correspondingly, the second subarray determination submodule is specifically used to: determine a set of filtered subarrays from the remaining radio frequency electrode subarrays in the radio frequency electrode array excluding all target radio frequency electrode subarrays; determine a new target radio frequency electrode subarray based on the filtered subarray set; and store the new target radio frequency electrode subarray in the initial sequence; wherein the filtered subarray set does not contain radio frequency electrode subarrays spatially adjacent to the last target radio frequency electrode subarray in the current initial sequence. The result of this method is that for the arbitrarily selected Nth and N+1th subarrays with adjacent activation times, these two sets of subarrays are not spatially adjacent.

[0063] Each radiofrequency electrode subarray outputs radiofrequency energy that acts only on a portion of the skin area to be treated. By identifying all radiofrequency electrode subarrays that are not adjacent to the last target radiofrequency electrode subarray in the current initial sequence from the remaining subarrays excluding all target subarrays, and then identifying new target radiofrequency electrode subarrays from these non-adjacent subarrays, significant local pain can be avoided due to the two radiofrequency electrode subarrays outputting radiofrequency energy acting on adjacent skin areas.

[0064] In another specific embodiment, the second subarray determining submodule is specifically used for:

[0065] From the remaining radio frequency electrode subarrays in the radio frequency electrode array excluding all target radio frequency electrode subarrays, a radio frequency electrode subarray is randomly selected as a new target radio frequency electrode subarray, and the new target radio frequency electrode subarray is stored in the initial sequence.

[0066] The time interval during which all radio frequency electrode subarrays in the target sequence are traversed and one output cycle is completed can be considered as a large cycle. Different large cycles correspond to different target sequences, where the activation order (order of output radio frequency energy) of the radio frequency electrode subarrays in each target sequence may differ. Therefore, when determining a new target radio frequency electrode subarray, the second subarray determination submodule can randomly select from the remaining electrode subarrays to generate different target sequences. In this application, for the same target treatment area, it is possible to control the execution of only one large cycle of treatment or to control the execution of more than one large cycle of treatment.

[0067] After obtaining all the identified target radio frequency electrode subarrays, the order of output radio frequency energy for target radio frequency electrode subarrays following the last radio frequency electrode subarray in the current initial sequence can also be randomly generated, ensuring that too much or too little radio frequency energy is delivered to the same skin area. As a demonstration of this method, the radio frequency output order, i.e., the activation timing, of the radio frequency electrode subarrays may differ in different target sequences.

[0068] Regardless of the specific implementation method chosen by the second subarray determination submodule, the target sequence obtained by the target sequence generation submodule follows a certain activation sequence. That is, the first element in the target sequence is the first RF electrode subarray that outputs RF energy after the RF electrode array is started, and the last element is the last RF electrode subarray that outputs RF energy after the RF electrode array is started.

[0069] After the first subarray determination submodule identifies the first RF electrode subarray that outputs RF energy after the RF electrode array starts and designates it as the target RF electrode subarray, the target sequence generation submodule can directly determine multiple target RF electrode subarrays corresponding to multiple output cycles by iterating through the remaining RF electrode subarrays in the RF electrode array. This ultimately ensures that each RF electrode subarray outputs RF energy in its corresponding output cycle. Alternatively, during the actual operation of the RF electrode array, before the start of the output cycle corresponding to the currently outputting RF energy RF electrode subarray or before the start of the overlapping period corresponding to that output cycle, the target sequence generation submodule can also determine the RF electrode subarrays that overlap with the output cycle of the currently outputting RF energy RF electrode subarray. That is, it can determine the (N+1)th subarray before the start of the output cycle of the Nth subarray or before its corresponding overlapping period, thus obtaining multiple target RF electrode subarrays to generate the target sequence. Here, the output cycle of an RF electrode subarray refers to the time period during which the RF electrode subarray outputs RF energy within a large cycle; the overlapping period corresponding to the output cycle of the Nth subarray refers to the time period during which the output cycles of the Nth and (N+1)th subarrays overlap.

[0070] This embodiment determines all target radiofrequency electrode subarrays based on the target sequence generation submodule, so that each radiofrequency electrode subarray outputs radiofrequency energy in its corresponding output cycle, thereby completing the treatment of all areas included in the skin region, and thus achieving the purpose of treatment.

[0071] The radio frequency electrode array control device provided in this embodiment will be described in detail below with reference to the functional module diagram shown in Figure 1.

[0072] The control module is used to control each RF electrode subarray in the target sequence to output RF energy sequentially, and to control the N+nth subarray to output RF energy during the overlapping period corresponding to the output period of the Nth subarray.

[0073] That is, in the target sequence, there are at least two radio frequency electrode subarrays with sequential activation times, which have overlapping periods of common output radio frequency energy. According to the activation time sequence, these two radio frequency electrode subarrays are the Nth subarray and the (N+n)th subarray, where N and n are both positive integers.

[0074] The following detailed description uses an implementation with n=1. For example, the radio frequency electrode subarray currently outputting radio frequency energy is designated as the first subarray, and the radio 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 subarray and the second subarray are two radio frequency electrode subarrays with adjacent activation times. In this case, the control module can control the second subarray to output radio frequency energy during the overlapping period corresponding to the output cycle of the first subarray.

[0075] The output cycles of each RF electrode subarray are sequential, with each output cycle having its own start and end times. For each RF electrode subarray other than the one corresponding to the last target RF electrode subarray in the target sequence, there is a partial overlap between its output cycle and the output cycle of the RF electrode subarray adjacent to its activation time. Specifically, there is a partial overlap between the output cycles of the Nth subarray and the (N+1)th subarray, known as the overlap period. The duration and start time of this overlap period can be set according to actual requirements.

[0076] In one embodiment, the Nth subarray and the N+1th subarray are radio frequency electrode subarrays that are selected from the target sequence and have adjacent activation times.

[0077] For multiple radio frequency (RF) electrode subarrays in the target sequence, the overlap can occur between two RF electrode subarrays with partially adjacent activation times, or between any two RF electrode subarrays with adjacent activation times, i.e., the Nth subarray and the (N+1)th subarray are any RF electrode subarrays with adjacent activation times in the target sequence. When any two RF electrode subarrays with adjacent activation times have overlapping periods, the overall activation time of the RF electrode array can be shortened further.

[0078] In one embodiment, the output period of any radio frequency electrode subarray is a continuous time period during the large cycle of traversing and activating all radio frequency electrode subarrays.

[0079] For example, when the Nth subarray and the (N+1)th subarray are RF electrode subarrays with adjacent activation times in the target sequence, for the RF electrode subarray (Nth subarray) other than the last target RF electrode subarray in the target sequence, there is a preset overlapping time period between its corresponding output period and the output period of the next RF electrode subarray (N+1 subarray). The number of overlapping time periods is 1, and the end time of the overlapping time period is the end time of the output period corresponding to the Nth subarray, so that the time period for the RF energy output by the RF electrode subarray (N+1 subarray) located after and adjacent to the RF electrode subarray in the target sequence is a continuous time period. The result presented by this embodiment is that the output period of any RF electrode subarray in the target sequence is a continuous time period, and any two RF electrode subarrays with adjacent activation times have an overlapping time period.

[0080] In one example of this embodiment, in the target sequence, the output period of the Nth subarray includes an overlapping period corresponding to the output period of the (N-1)th subarray and an overlapping period corresponding to the output period of the (N+1)th subarray, where N is a positive integer other than 1, and the maximum value of N is less than the total number of radio frequency electrode subarrays in the radio frequency electrode array.

[0081] For example, for each RF electrode subarray in the target sequence except the last RF electrode subarray, the overlap period corresponding to the output period of the RF electrode subarray adjacent to the next activation time can be preset to be a continuous segment of the output period. That is, the overlap period can be a certain percentage of the output period, such as 30%, 40%, or half of the output period. This percentage can be less than or equal to 50%, ensuring that in any overlap period of a large period, at most two RF electrode subarrays are in the output period, i.e., at most two RF electrode subarrays simultaneously output RF energy.

[0082] In a more specific example, the start time of the overlapping period corresponding to the output period of the Nth subarray and the (N+1)th subarray is preset to be the midpoint of the output period of the Nth subarray, and the end time of the overlapping period is the end time of the output period. The result of this implementation is that, in the target sequence, except for the first and last RF electrode subarrays, the output periods of all other RF electrode subarrays are within the overlapping period.

[0083] Figure 3 shows a time-cycle diagram for this example, illustrating the relationship between the duration of multiple consecutive output cycles and the operating time of the RF electrode array when the overlap period is set to a consecutive half-cycle within the output cycle, and the start time of the overlap period is the midpoint of the output cycle. In Figure 3, A, B, and C represent three consecutive output cycles, i.e., the output cycles of three RF electrode subarrays with adjacent activation times. As can be seen from Figure 3, for each RF electrode subarray in the target sequence except the last one, by setting the overlap period corresponding to its output cycle and the output cycle of the RF electrode subarray in the next activation time to a consecutive half-cycle within that output cycle, with the start time of this overlap period being the midpoint of the output cycle, the output cycle of each RF electrode subarray in the target sequence except the first and last RF electrode subarrays consists only of the overlap period corresponding to the output cycle of the RF electrode subarray adjacent to the previous activation time and the overlap period corresponding to the output cycle of the RF electrode subarray adjacent to the next activation time, and these two overlap periods are consecutive. This method ensures that the time periods during which each radiofrequency electrode subarray outputs radiofrequency energy are completely continuous. Except for the first and last radiofrequency electrode subarrays in the target sequence, when each radiofrequency electrode subarray outputs radiofrequency energy, there are no time periods outside the non-overlapping periods. That is, the output cycles of all other radiofrequency electrode subarrays are within the overlapping periods. This method can significantly reduce the treatment time, that is, reduce the duration of action of the radiofrequency electrode arrays, and reduce the user's pain as a whole.

[0084] In another example of this embodiment, in the target sequence, the output cycle of at least a portion of the RF electrode subarray includes a time period in which only that RF electrode subarray outputs RF energy.

[0085] For example, for each RF electrode subarray in the target sequence except the last RF electrode subarray, the duration of the overlap period between its output period and the output period of the RF electrode subarray adjacent to the next activation time can be preset to be less than half the duration of that output period. That is, in this case, the start time of the overlap period between the output period of the Nth subarray and the output period of the (N+1)th subarray can be preset to be the time corresponding to the end time of the output period of the Nth subarray minus the duration of the overlap period. The result presented by this embodiment is that, in the target sequence, except for the first and last RF electrode subarrays, at least some of the other RF electrode subarrays have non-overlapping time periods, that is, time periods during which only that RF electrode subarray outputs RF energy.

[0086] Figure 4 shows a time-cycle diagram for this example. It illustrates the relationship between the duration of multiple consecutive output cycles and the operating time of the RF electrode array when the overlapping period is set to a time interval shorter than half a cycle of the output cycle, and the start time of the overlapping period is the time corresponding to the end time of the output cycle minus the duration of the overlapping period. In Figure 4, A, B, and C represent three consecutive output cycles, i.e., the output cycles of three RF electrode subarrays with adjacent activation times. As shown in Figure 4, for each RF electrode subarray in the target sequence except the last RF electrode subarray, the duration of the overlap period between its output period and the output period of the RF electrode subarray in the next activation sequence is set to be less than half a period of the output period. In this case, the start time of the overlap period is the time corresponding to the end time of the output period minus the duration of the overlap period. In this case, the output period of each RF electrode subarray in the target sequence except the first and last RF electrode subarrays consists of the overlap period corresponding to the output period of the RF electrode subarray adjacent to the previous activation sequence, the time period during which it only outputs RF energy, and the overlap period corresponding to the output period of the RF electrode subarray adjacent to the next activation sequence. These three periods are continuous. This method ensures that the time periods during which each RF electrode subarray outputs RF energy are completely continuous. Except for the first and last RF electrode subarrays in the target sequence, each RF electrode subarray outputs RF energy with continuous overlapping and non-overlapping time periods. Among them, the non-overlapping time period means that each RF electrode subarray's output cycle has at least one time period during which only that RF electrode subarray outputs RF energy. By overlapping the working time of the RF electrode subarrays, the working duration of the RF electrode arrays is reduced, and the user's pain experience is reduced as a whole.

[0087] In another embodiment, during the large cycle of traversing and activating all RF electrode subarrays, the output cycle of any RF electrode subarray is a discontinuous time period.

[0088] For example, for any RF electrode subarray in the target sequence other than the first RF electrode subarray, the number of time periods corresponding to its output period is at least 2 and the at least 2 time periods are not consecutive, and / or the number of overlapping time periods corresponding to the output period of the RF electrode subarray adjacent to the next activation time is 1 and the end time of the overlapping time period is not the end time of the output period of the RF electrode subarray, so that the time period for the RF energy output by any RF electrode subarray in the target sequence other than the first RF electrode subarray and the last RF electrode subarray is a non-consecutive time period.

[0089] In one example of this embodiment, during the large cycle of traversing and activating all RF electrode subarrays, the output cycle of the N+n subarray includes at least two discontinuous RF energy output time periods. In one specific instance, for these at least two discontinuous RF energy output time periods, the preceding RF energy output time period overlaps with the output cycle of the Nth subarray; in another specific instance, the following RF energy output time period overlaps with the output cycle of the Nth subarray.

[0090] Where N is a positive integer, and the maximum value of N is less than the total number of RF electrode subarrays in the RF electrode array, that is, the (N+1)th subarray can be the last RF electrode subarray in the target sequence.

[0091] Figure 5 shows a time-cycle diagram for this example, illustrating the relationship between the duration of multiple consecutive output cycles and the operating time of the RF electrode array when the overlapping time period is set to a quantity of 1 and the end time is not the end time of the output cycle of the RF electrode subarray. In Figure 5, A, B, and C represent three consecutive output cycles, i.e., the output cycles of three RF electrode subarrays with adjacent activation times. As shown in Figure 5, for each RF electrode subarray in the target sequence except the last one, by setting the overlapping time period corresponding to its output cycle to a quantity of 1, and ensuring that the end time of the overlapping time period is not the end time of its output cycle, the output RF energy of all RF electrode subarrays (any N+1 subarray) except the first RF electrode subarray to output RF energy after the RF electrode array is activated (the 1st subarray) is not completely continuous. Each RF electrode subarray, except for the first and last RF electrode subarrays in the target sequence, has a non-continuous overlapping time period with the two RF electrode subarrays adjacent to it in the target sequence's activation time. That is, in Figure 5, the output cycle of any N+1 subarray includes two non-continuous RF energy output time periods: the first RF energy output time period overlaps with the output cycle of the Nth subarray, and the second RF energy output time period overlaps with the output cycle of the N+1 subarray. This method can also reduce the operating time of the RF electrode array and reduce user discomfort overall.

[0092] As can be seen from Figures 3-5, the number of RF electrode subarrays in the output cycle is 2 during any overlapping time period, that is, the number of RF electrode subarrays that output RF energy at any time is 2.

[0093] For each radiofrequency electrode subarray in the target sequence except for the last target radiofrequency electrode subarray, by setting overlapping time periods, the time periods during which two radiofrequency electrode subarrays with adjacent activation times in the target sequence output radiofrequency energy overlap. This avoids treatment gaps during the operation of the radiofrequency electrode array (i.e., avoids stop time periods within the large cycle of radiofrequency energy output by the radiofrequency electrode array). Moreover, when the total number of radiofrequency electrodes included in the radiofrequency electrode array is large, the number of time-division treatments of the radiofrequency electrode array can be reduced, thereby shortening the time required to complete one treatment and reducing the overall treatment time. At the same time, by reducing the skin area treated at the same time, the patient's perception and pain from radiofrequency energy can be reduced.

[0094] Of course, when only the last radiofrequency electrode subarray in the target sequence outputs radiofrequency energy, it indicates that the current output cycle is the last output cycle to complete this treatment. At this time, all the other radiofrequency electrode subarrays in the target sequence except for the last radiofrequency electrode subarray have completed the treatment of the skin area they are targeting.

[0095] Next, based on the description of the implementation method with n=1 above, the implementation method with n>1 in this application will be briefly described.

[0096] In this type of implementation where n>1, the control module controls the (N+n)th subarray to output radio frequency energy during the overlapping period corresponding to the output cycle of the Nth subarray. That is, in the target sequence generated by the subarray determination module, the Nth and (N+n)th subarrays, whose activation times are sequential but not adjacent, share a common overlapping period. This type of implementation can also, as in the n=1 embodiment described above, utilize the overlapping period for energy accumulation, shortening the overall operating time and reducing user discomfort.

[0097] In this type of implementation where n>1, if the output period of each RF electrode subarray is a continuous time period within a large period, then the Nth, N+1th, ..., N+nth subarrays will inevitably have a common overlapping time period. To avoid excessively large numbers of RF electrode subarrays simultaneously in the output period, this application preferably sets the number of RF electrode subarrays simultaneously in the output period to be less than a preset value, which can be, for example, 3 or 4.

[0098] In this type of implementation where n>1, if there are RF electrode subarrays with discontinuous output periods within a large period, then there can be RF electrode subarrays between the Nth subarray and the (N+n)th subarray that do not overlap with the Nth subarray in terms of time periods. For example, the output period of the first subarray is divided into two discontinuous RF energy output time periods (referred to as output periods), the output period of the second subarray does not overlap with the output period of the first subarray and is at least partially located between the two output periods of the first subarray, and the output period of the third subarray overlaps with the later output period of the first subarray.

[0099] For implementations where n > 1, other technical solutions that do not conflict with implementations where n = 1 can be found in the description above, such as the function and structure of the subarray determination module, which will not be repeated here.

[0100] It needs to be emphasized again that the pain sensation generated by the radio frequency electrode array is closely related to the area of ​​the radio frequency energy output at the same time. Regardless of whether n=1 or n>1, in some embodiments of this application, a certain radio frequency electrode subarray may overlap with more than one other radio frequency electrode subarray during the same period. No matter how many radio frequency electrode subarrays overlap during the same period, the radio frequency electrode subarrays that are simultaneously in the output cycle are not adjacent to each other in spatial position during any overlapping period, so as to avoid significant pain sensation in the local skin.

[0101] Preferably, the RF electrode array control device provided in this embodiment further includes an output statistics module. The output statistics module is used to count the cumulative RF energy value output by each RF electrode subarray from the first activation time to the current time. The control module is also used to control the RF electrode subarray to be in a no-power output state if the cumulative RF energy value of the RF electrode subarray is greater than or equal to a preset RF energy threshold.

[0102] Historical output cycle refers to the output cycle corresponding to the radio frequency electrode subarray that has output radio frequency energy. For each radio frequency electrode subarray, this embodiment calculates the cumulative radio frequency energy value output by the radio frequency electrode subarray from the first activation time to the current time, and controls the radio frequency electrode subarray to be in a no-power output state according to a preset radio frequency energy threshold. This can avoid excessive radio frequency energy output to the same skin area of ​​the human body, which may cause pain.

[0103] Preferably, in the radio frequency electrode array control device provided in this embodiment, the control module further includes a temperature parameter acquisition unit and an output power adjustment unit.

[0104] The temperature parameter acquisition unit is used to acquire real-time temperature parameters collected by the temperature sensor; the output power adjustment unit is used to adjust the real-time output power of the RF electrode subarray that outputs RF energy according to the real-time temperature parameters.

[0105] Radiofrequency therapy devices can be equipped with one or more temperature sensors to detect temperature changes in the skin surface and deep tissues. Additionally, when the radiofrequency electrode subarray outputs radiofrequency energy at a fixed power, the temperature of the affected skin area will rise, and this rise in skin temperature may cause pain.

[0106] Based on this, as a specific implementation, the output power adjustment unit is specifically used to: when the real-time temperature parameter is less than a preset temperature threshold, cause the control module to control the current output radio frequency energy RF electrode subarray to output radio frequency energy at a preset power, wherein the real-time temperature parameter refers to the temperature parameter of the skin area acted upon by the current output radio frequency energy RF electrode subarray; when the real-time temperature parameter is greater than or equal to the preset temperature threshold, adjust the output power of the current output radio frequency energy RF electrode subarray, and cause the control module to control the RF electrode subarray to output radio frequency energy at the adjusted output power, so that the temperature of the skin area acted upon by the current output radio frequency energy RF electrode subarray does not exceed the preset temperature threshold, wherein the real-time output power is less than the preset power.

[0107] This embodiment obtains real-time temperature parameters collected by a temperature sensor and controls the temperature of the skin area affected by the radio frequency electrode subarray that is currently outputting radio frequency energy to not exceed a preset temperature threshold. That is, when the radio frequency electrode subarray outputs radio frequency energy, the temperature of the skin area it affects first rises and then remains constant, which can avoid causing pain to the human body.

[0108] Preferably, the radio frequency electrode subarray includes at least two radio frequency electrodes that are not adjacent to each other.

[0109] For example, if the three radiofrequency electrodes at point A and the two radiofrequency electrodes at point B in Figure 2 are designated as the first subarray of the target sequence, then subsequent control of this first subarray actually involves controlling all five radiofrequency electrodes simultaneously. This means treating multiple spatially non-adjacent radiofrequency electrodes as a single unit, forming a radiofrequency electrode subarray for a specific activation time in the target sequence. By identifying multiple spatially non-adjacent radiofrequency electrodes as a single radiofrequency electrode subarray, the number of times the target radiofrequency electrode subarray needs to be identified from the existing array can be reduced during treatment, thus reducing the number of output cycles and consequently the time required to complete one treatment. Furthermore, given the same total treatment area, a total treatment area composed of multiple non-adjacent treatment areas (i.e., the areas of action corresponding to the radiofrequency electrodes) results in less pain compared to a total treatment area composed of adjacent treatment areas.

[0110] Preferably, in the radio frequency electrode array control device provided in this embodiment, the number of radio frequency electrodes in each radio frequency electrode subarray is equal or the difference in number is less than a preset number threshold, so as to control the uniformity of the treatment energy distribution.

[0111] The radio frequency electrode array control device provided in this embodiment includes a subarray determination module and a control module. The subarray determination module generates a target sequence based on multiple radio frequency electrode subarrays of the radio frequency electrode array. The control module then controls each radio frequency electrode subarray in the target sequence to output radio frequency energy sequentially. During the process of delivering radio frequency energy to the skin treatment area using radio frequency electrodes, the treatment area corresponding to each radio frequency electrode subarray is a local area of ​​the entire treatment area. By performing time-division treatment on each local area, the instantaneous treatment area at each moment is reduced, thereby alleviating the pain in the local area. At the same time, the control module controls the N+1th subarray to output radio frequency energy during the overlapping period corresponding to the output cycle of the Nth subarray. This ensures that the output cycles of two radio frequency electrode subarrays with adjacent activation times in the target sequence have a partial overlap time period, avoiding treatment gaps in the working process of the radio frequency electrode array that would lead to an increase in the overall treatment time. Moreover, when the total number of radio frequency electrodes in the radio frequency electrode array is large, the energy accumulation during the overlapping period can shorten the overall treatment time, thereby further reducing the user's pain.

[0112] When the radio frequency electrode array control device provided in this embodiment is applied to a radio frequency therapy device, the radio frequency therapy device includes a radio frequency power supply and a radio frequency electrode array. The radio frequency electrode array is electrically connected to the radio frequency power supply. The radio frequency electrode array includes multiple radio frequency electrode subarrays, and each radio frequency electrode subarray includes at least one radio frequency electrode.

[0113] Specifically, the radio frequency power supply may consist of only one, i.e., a single radio frequency power supply powers the radio frequency electrode array. Alternatively, the radio frequency power supply may consist of multiple, i.e., multiple radio frequency power supplies are respectively connected to the switching module of the radio frequency therapy device. The switching module is controlled by the control unit of the radio frequency therapy device and is used to realize the connection and disconnection between the radio frequency electrode array and the radio frequency power supply, so as to regulate the output and transmission of radio frequency energy.

[0114] Example 2

[0115] Based on the same inventive concept, and referring to FIG6, this application also provides a radiofrequency therapy device. The radiofrequency therapy device of this embodiment will be described in detail below with reference to the functional module diagram shown in FIG6.

[0116] The radiofrequency therapy device includes a radiofrequency power supply, a radiofrequency electrode array, and a radiofrequency electrode array control device as described in Example 1. Both the radiofrequency power supply and the radiofrequency electrode array control device are connected to the radiofrequency electrode array.

[0117] In one specific embodiment, the radiofrequency therapy device includes a radiofrequency power supply, and each radiofrequency electrode subarray is connected in parallel and then connected to the radiofrequency power supply. The output power of the radiofrequency power supply remains unchanged during the overlapping period.

[0118] When the radiofrequency therapy device contains only one radiofrequency power supply, all radiofrequency electrode subarrays contained in the radiofrequency electrode array are powered by that same power supply. In this embodiment, for each radiofrequency electrode subarray (Nth subarray) in the target sequence except for the last radiofrequency electrode subarray, when the time period during which the radiofrequency energy is output by the radiofrequency electrode subarray overlaps with the time period corresponding to its output cycle, the power is distributed between the radiofrequency electrode subarray and another radiofrequency electrode subarray (N+1th subarray) in the target sequence whose activation time is after it and adjacent to it, through a parallel connection.

[0119] Specifically, for each RF electrode subarray in the target sequence except the last RF electrode subarray, if the total power output of the RF power supply is a fixed value, then because the RF power supply needs to output power to the Nth subarray and the (N+1)th subarray, the average power of the Nth subarray during the overlapping period corresponding to its output cycle is less than its average power during other periods of the output cycle excluding the overlapping period; if the total power output of the RF power supply is a variable value, then the total output power of the RF electrode array can be increased during the overlapping period corresponding to the output cycle of the RF electrode subarray by the RF electrode array control device.

[0120] In another specific embodiment, the radio frequency power supply includes multiple sub-radio frequency power supplies, each of which is used to control the radio frequency electrode sub-arrays corresponding to different output cycles, so that the output power of each radio frequency electrode sub-array remains unchanged.

[0121] When a radiofrequency therapy device contains multiple sub-radiofrequency power supplies, different radiofrequency electrode subarrays can be controlled independently by different sub-radiofrequency power supplies. Of course, one sub-radiofrequency power supply can also control multiple radiofrequency electrode subarrays. For example, when there are 20 radiofrequency electrode subarrays and 5 sub-radiofrequency power supplies, each sub-radiofrequency power supply can control 4 radiofrequency electrode subarrays. As a specific implementation, for each radiofrequency electrode subarray (Nth subarray) in the target sequence except for the last one, the sub-radiofrequency power supply connected to this subarray is different from the sub-radiofrequency power supply connected to another adjacent radiofrequency electrode subarray (N+1th subarray) in the target sequence whose activation time is subsequent. This avoids a decrease in the average power of the subarray during the overlapping period corresponding to its output cycle, thereby shortening the treatment time.

[0122] In one specific embodiment, the radiofrequency therapy device includes a monopolar mode in which all radiofrequency electrodes contained in a single radiofrequency electrode subarray have the same polarity; the radiofrequency therapy device also includes an electrode plate with the opposite polarity to the radiofrequency electrode array.

[0123] Specifically, when the radiofrequency therapy device is in monopolar mode, for each radiofrequency electrode subarray, the polarity of all the needle electrodes of the radiofrequency electrodes it contains is the same, and the non-needle electrodes of the other polarity can be attached to the back, buttocks, or other parts of the human body.

[0124] 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 of opposite polarity.

[0125] Specifically, the needle electrodes of the radio frequency (RF) electrode have both positive and negative polarities. The RF electrodes with positive and negative polarities can together form an RF electrode subarray.

[0126] By selecting an appropriate working mode based on the patient's specific condition and treatment needs, better treatment outcomes can be achieved.
