[0002] The core issue in radiofrequency ablation is how to stably and uniformly deliver specified radiofrequency energy to a designated tissue depth to achieve the desired treatment temperature and therapeutic effect. Methods for targeted radiofrequency energy delivery mainly include using minimally invasive microneedles to directly deliver radiofrequency energy to deep tissues, or using a non-invasive method of "radiofrequency heating + cooling the epidermis." Although cooling with a cooling agent is used to attempt to lower the epidermal temperature, the horizontal heating area of ​​the epidermis is the same as that of the deep tissue, resulting in excessive heat concentration on the epidermis. Therefore, for non-invasive radiofrequency ablation, there is currently no good method to focus radiofrequency energy to deep tissues to achieve the desired treatment effect.

[0046] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0047] The core problem of RF treatment is how to stably and uniformly output the specified RF energy to the tissue layer at a specified depth to achieve the specified target treatment temperature and treatment effect. The methods of target directional RF energy mainly include the method of directly delivering RF energy to deep tissue through inserted micro-needles by using minimally invasive micro-needles, or the method of non-invasive "RF heating + spraying cold medium skin cooling". Although the cooling method of spraying cold medium is used to try to reduce the skin temperature, the horizontal heating area of the skin is the same as that of the deep tissue, which leads to excessive heat concentration on the skin. Therefore, there is no good method to focus RF energy on deep tissue to achieve the expected treatment effect for non-invasive RF.

[0048] Therefore, the present application correspondingly provides a non-invasive RF therapeutic head and its control scheme to realize non-invasive focused RF on deep tissue.

[0049] Referring to Figure 1 The embodiments of the present application disclose a non-invasive RF therapeutic head, which comprises:

[0050] The non-invasive radio frequency treatment head body is provided with a treatment surface 11;

[0051] A plurality of pairs of radio frequency electrode groups 12, including at least two pairs of target radio frequency electrode groups, the center positions of the target radio frequency electrode groups overlap, and the distribution form of the target radio frequency electrode groups is determined based on a preset focusing treatment depth; wherein the driving mode of the plurality of pairs of radio frequency electrode groups 12 to the action area is an alternating driving mode, and each pair of radio frequency electrode groups 12 includes a first radio frequency electrode and a second radio frequency electrode with opposite polarities.

[0052] In the embodiment, the non-invasive radio frequency treatment head comprises a non-invasive radio frequency treatment head body, a treatment surface 11 is arranged on the non-invasive radio frequency treatment head body, and a plurality of pairs of radio frequency electrode groups 12 are distributed on the treatment surface 11, wherein the plurality of pairs of radio frequency electrode groups 12 comprise at least two pairs of target radio frequency electrode groups, the center positions of the target radio frequency electrode groups overlap, and the distribution form of the target radio frequency electrode groups on the treatment surface 11 can be determined based on a preset focusing treatment depth. Further, because the center positions of each pair of target radio frequency electrode groups overlap, when different target radio frequency electrode groups output radio frequency energy, although the positions of the radio frequency electrodes of each target radio frequency electrode group are different, the radio frequency energy will pass through the center position, so that in the entire output period, the deep area of the center position receives more radio frequency energy than other positions, resulting in more cumulative radio frequency energy received, that is, the radio frequency energy can be focused on the same position. In addition, through time sequence alternating driving, the transmission path of the radio frequency energy between different target radio frequency electrode groups can be avoided. It can be understood that if there are multiple pairs of radio frequency electrode groups outputting radio frequency energy at the same time, the distribution of positive and negative electrodes is very chaotic, and the closest positive and negative electrodes will be queued first, resulting in few current passing through the central area, and the skin close to the radio frequency electrode group 12 will be damaged due to the output of the radio frequency energy by the radio frequency electrode group 12. Therefore, the driving mode of the multiple pairs of radio frequency electrode groups 12 outputting radio frequency energy to the target area is an alternating driving mode, for example, there are a first pair of radio frequency electrode groups, a second pair of radio frequency electrode groups, and a third pair of radio frequency electrode groups, the first pair of radio frequency electrode groups outputs radio frequency energy in the Nth driving, the second pair of radio frequency electrode groups outputs radio frequency energy in the N+1th driving, and the third pair of radio frequency electrode groups outputs radio frequency energy in the N+2th driving. Because different pairs of radio frequency electrode groups are at different skin positions, the alternating ring driving mode can avoid the same skin position being damaged by radio frequency all the time, and reduce skin damage as much as possible, and on the other hand, in one cycle of treatment, the tissue close to the middle deep part will be heated multiple times more than the electrode, so that the focusing radio frequency treatment effect can be achieved. It should be noted that in the embodiment, in addition to the alternating driving mode which can reduce skin damage, the total area of the electrode position is also greater than the area of the overlapping region, so that the heat generated by the radio frequency treatment on the skin can also be shared, and the skin damage can be reduced.

[0053] The application has the following beneficial effects: the non-invasive radio frequency treatment head body of the application is provided with a treatment surface; a plurality of pairs of radio frequency electrode groups, including at least two pairs of target radio frequency electrode groups, the center positions of the target radio frequency electrode groups overlap, and the distribution form of the target radio frequency electrode groups is determined based on a preset focusing treatment depth; wherein the driving mode of the plurality of pairs of radio frequency electrode groups for outputting radio frequency energy to the action area is an alternating driving mode, and each pair of radio frequency electrode groups includes a first radio frequency electrode and a second radio frequency electrode with opposite polarities. As can be seen, the target radio frequency electrode groups are distributed on the treatment surface of the non-invasive radio frequency treatment head body based on the preset focusing treatment depth, that is, the radio frequency energy output by the target radio frequency electrode groups can reach different preset focusing treatment depths, and because the center positions of each pair of target radio frequency electrode groups overlap, the radio frequency electrode positions of different target radio frequency electrode groups are different, but the radio frequency energy output by them alternately will pass through the deep area corresponding to the center position, but will not output radio frequency energy repeatedly to other positions except the center position, so the deep area of the center position receives more radio frequency energy than the deep area of other positions, resulting in more cumulative radio frequency energy, which can focus radio frequency energy at the same position and can perform focused radio frequency treatment on the action area, that is, non-invasive focused radio frequency treatment on deep tissues is realized. Further, if there are a plurality of pairs of radio frequency electrode groups outputting radio frequency energy at the same time, the distribution of positive and negative electrodes is very chaotic, which will preferentially form teams of the nearest positive and negative electrodes, resulting in few current passing through the central area. Therefore, the driving mode of the plurality of pairs of radio frequency electrode groups for outputting radio frequency energy to the target area is an alternating driving mode, that is, the application does not allow all radio frequency electrode groups to output radio frequency energy at the same time, which ensures that the radio frequency energy can accurately pass through the action area, avoids interference from other electrodes, and also reduces damage to the epidermis.

[0054] In a specific embodiment, the distribution form is a single-layer distribution form, and the target radio frequency electrode groups are used to realize a single depth of the preset focusing treatment depth. The center distance of the first radio frequency electrode and the second radio frequency electrode with opposite polarities of each target radio frequency electrode group is equal.

[0055] In some embodiments of the application, the single-layer distribution form is any one of a single-layer regular polygon distribution form, a single-layer circular ring arc distribution form, and a single-layer X-shaped distribution form, and can also be other shapes, which are not listed one by one here.

[0056] The preset focusing treatment depth is a single depth, and the distribution form of each pair of target radio frequency electrode groups is a single-layer distribution form, that is, not only the center positions of each pair of target radio frequency electrode groups overlap, but also the distances between each pair of target radio frequency electrode groups and the center position are the same; for example Figure 2 a specific single-layer distribution form diagram, Figure 2The middle (a) is a single-layered regular polygon distribution form, Figure 2 The middle (b) is a single-layered circular arc distribution form, Figure 2 The middle (c) is a single-layered X-shaped distribution form. As can be seen, in the single-layered distribution form, the center positions of the target radio frequency electrode group Aa and the target radio frequency electrode group Bb are the same, and the distances between the center positions and the target radio frequency electrode group Aa and the target radio frequency electrode group Bb are the same.

[0057] In another embodiment, the distribution form is a multi-layered distribution form, and the target radio frequency electrode group is used to achieve a plurality of preset focusing treatment depths. In the multi-layered distribution form, the center distances between the first radio frequency electrode and the second radio frequency electrode of each pair of target radio frequency electrode groups located in different layers and having opposite polarities are different, and the center distances between the first radio frequency electrode and the second radio frequency electrode of each pair of target radio frequency electrode groups located in the same layer and having opposite polarities are the same, wherein the center distances between the first radio frequency electrode and the second radio frequency electrode of each pair of target radio frequency electrode groups and having opposite polarities are determined based on each preset focusing treatment depth. In this embodiment, the target radio frequency electrode group at least includes a first target radio frequency electrode group corresponding to a first preset focusing treatment depth and a second target radio frequency electrode group corresponding to a second preset focusing treatment depth, and the first target radio frequency electrode group and the second target radio frequency electrode group each include at least two pairs of radio frequency electrode groups, wherein the center distance between the first radio frequency electrode and the second radio frequency electrode of the first target radio frequency electrode group is smaller than the center distance between the first radio frequency electrode and the second radio frequency electrode of the second target radio frequency electrode group. The center of each pair of target radio frequency electrode groups is the center between the first radio frequency electrode and the second radio frequency electrode of the radio frequency electrode group, and the center distance of each pair of radio frequency electrode groups is half of the distance between the first radio frequency electrode and the second radio frequency electrode of the radio frequency electrode group.

[0058] In some embodiments of the present application, the multi-layered distribution form is any one of a multi-layered circular arc distribution form, a multi-layered elliptical arc distribution form, a multi-layered rectangular distribution form, a multi-layered single-row distribution form, and a multi-layered double-row distribution form, and can also be other shapes, which are not listed here.

[0059] The preset focusing treatment depth is a plurality of depths, and the distribution form of each pair of target radio frequency electrode groups is a multi-layered distribution form, that is, although the center positions of each pair of target radio frequency electrode groups on the surface parallel to the skin overlap, the distances between the radio frequency electrode groups of different layers and the center positions are not the same; further, the multi-layered distribution form is any one of a multi-layered circular arc distribution form, a multi-layered elliptical arc distribution form, a multi-layered rectangular distribution form, a multi-layered single-row distribution form, and a multi-layered double-row distribution form; for example Figure 3 A specific multi-layered distribution form is shown in the diagram, Figure 3 The middle (a) is a multi-layered circular arc distribution form, Figure 3The middle (b) is a multi-layer elliptical arc distribution form, Figure 3 The middle (c) is a multi-layer rectangular distribution form, Figure 3 The middle (d) is a multi-layer single-row distribution form, Figure 3 The middle (e) is a multi-layer double-row distribution form. As can be seen, the center positions of each pair of target radio frequency electrode groups overlap, the distance between each pair of target radio frequency electrode groups in the same layer and the center position is the same, that is, the center distance of each pair of target radio frequency electrode groups in the same layer is the same, but the distance between each pair of target radio frequency electrode groups in different layers and the center position is not the same, that is, the center distance of each pair of target radio frequency electrode groups in different layers is not the same. Because of the distribution of different layers, the focusing treatment depth that can be reached by the radio frequency energy output by each pair of radio frequency electrode groups is different, thereby realizing multi-depth radio frequency focusing treatment. The radio frequency electrode spacing of the multi-layer circular arc distribution form is related to the size of the treatment head and the preset focusing treatment depth, and ranges from 5mm to 50mm, and can be 10mm or 20mm. The ring spacing of the multi-layer circular arc distribution form is related to the different layer depth increment, and ranges from 2mm to 10mm, and can be 5mm.

[0060] In this embodiment, the alternating driving mode includes sequential alternating driving, interval alternating driving, and random alternating driving.

[0061] When only a pair of radio frequency electrode groups outputs radio frequency energy, it follows the conventional bipolar radio frequency output characteristics, that is, the current density is highest near the electrode, the tissue heating effect is also best, and damage to the skin is caused. In order to avoid damage to the same skin position for a long time and avoid magnetic field interference, the driving mode of the radio frequency electrode groups in this embodiment is an alternating driving mode.

[0062] In a specific embodiment of sequential alternating driving, for example Figure 4 A specific radio frequency electrode group distribution diagram is shown in FIG. 1, which includes radio frequency electrode group Aa, radio frequency electrode group Bb, radio frequency electrode group Cc, and radio frequency electrode group Dd. When the alternating cycle driving mode is sequential alternating cycle driving, the specific radio frequency electrode group output radio frequency energy sequence is as shown in FIG. 2, that is, in a round of treatment cycle, the radio frequency electrode group Aa, the radio frequency electrode group Bb, the radio frequency electrode group Cc, and the radio frequency electrode group Dd are sequentially driven. Figure 5

[0063] In a specific embodiment of interval alternating driving, for example Figure 6 ​Another RF electrode group distribution diagram is shown. In sequence, each pair of RF electrode groups is arranged in sequence, namely RF electrode group Aa, target RF electrode group Bb, RF electrode group Cc, RF electrode group Dd and RF electrode group Ee. When the alternate driving mode is interval alternation driving, in one cycle of treatment, RF electrode group Aa, RF electrode group Cc, RF electrode group Ee, RF electrode group Bb and RF electrode group Dd are driven in sequence, that is, they are not driven in sequence, but are driven at intervals, so as to avoid the activation of the RF electrode groups adjacent in time and space, and avoid the energy being concentrated in the adjacent area for a short time, causing local excessive damage.

[0064] Further, the random alternation driving is to randomly select a pair of RF electrode groups from all RF electrode groups as the current RF electrode group, and control the electrode group to output RF energy.

[0065] It should be noted that the alternate driving mode can be alternate cycle driving mode or alternate non-cycle driving mode, that is, the sequence alternation driving can be sequence alternation cycle driving or sequence alternation non-cycle driving, the interval alternation driving can be interval alternation cycle driving or interval alternation non-cycle driving, and the random alternation driving can be random alternation cycle driving or random alternation non-cycle driving.

[0066] In this embodiment, the first RF electrode and the second RF electrode of each pair of RF electrode groups are in opposite positions.

[0067] It can be understood that each pair of RF electrode groups includes a first RF electrode and a second RF electrode, the first RF electrode and the second RF electrode are in opposite positions, and the first RF electrode is of a first polarity and the second RF electrode is of a second polarity, for example, the first RF electrode is positive and the second RF electrode is negative; wherein, for example Figure 7 A specific RF depth diagram is shown. The treatment depth d is 1 / 2 of the distance between the first RF electrode and the second RF electrode in each pair of RF electrode groups. It should be noted that the RF electrode size cannot be too small, otherwise the heat will be concentrated at the electrode position.

[0068] In this embodiment, the middle region of the non-invasive RF treatment head includes a cooling module, the cooling module includes a cold spray device and a heat uniformizing sheet; or the cooling module includes a semiconductor refrigerator and a heat conducting sheet.

[0069] Further, in order to reduce the damage to the epidermal tissue, a cooling module can be arranged in the middle region of the non-invasive radio frequency treatment head, and the cooling module is used to reduce the temperature of the epidermal tissue, thereby reducing the damage; wherein one specific cooling module includes a cold spray device and a heat uniformizing sheet, and another specific cooling module includes a thermoelectric cooler (TEC) and a heat conducting sheet, which can be selected according to specific circumstances.

[0070] In the embodiment, the middle region of the non-invasive radio frequency treatment head includes a heating sheet, which is used to preheat and heat stimulate the target region.

[0071] Because the tolerance of each patient to pain is different, if the patient has a high tolerance to pain, the treatment temperature is heated as soon as possible to reduce the treatment time, so a heating sheet can be arranged in the middle region of the non-invasive radio frequency treatment head, and the heating sheet is used to preheat and heat stimulate the target region, thereby reducing the treatment time and improving the treatment efficiency.

[0072] In the embodiment, the middle region of the non-invasive radio frequency treatment head includes a contact sensor, which is used to identify whether each radio frequency electrode group contacts the epidermal layer of the target region; a temperature sensor, which is used to collect the temperature information of the target region; and a displacement sensor, which is used to determine the displacement information of the non-invasive radio frequency treatment head in the radio frequency treatment, so as to perform radio frequency treatment on the target region based on the displacement information.

[0073] The middle region of the non-invasive radio frequency treatment head can also be provided with a contact sensor, a temperature sensor and a displacement sensor, the contact sensor can identify whether each radio frequency electrode group contacts the epidermal layer of the target region, the temperature sensor can collect the temperature information of the target region, so as to perform radio frequency treatment based on the temperature information; and the displacement sensor can determine the displacement information of the non-invasive radio frequency treatment head in the radio frequency treatment, so as to perform radio frequency treatment on the target region based on the displacement information, accurately grasp the positional relationship between the treatment head and the target region, and perform more accurate radio frequency treatment.

[0074] In the embodiment, the middle region of the non-invasive radio frequency treatment head includes a monopolar radio frequency electrode, wherein the radio frequency energy output time of the monopolar radio frequency electrode is different from the radio frequency energy output time of each pair of radio frequency electrode groups.

[0075] The middle region of the non-invasive radio frequency treatment head can be provided with a monopolar radio frequency electrode, but because if the monopolar radio frequency electrode is simultaneously emitted with other radio frequencies, the current will be disturbed, so the radio frequency energy output time of the monopolar radio frequency electrode is different from the radio frequency energy output time of each pair of radio frequency electrode groups, so as to avoid the occurrence of current disturbance.

[0076] In the embodiment, the middle region of the non-invasive radio frequency treatment head comprises an ultrasonic emission window for emitting ultrasonic energy to the target region, wherein the time of emitting the ultrasonic energy at least partially overlaps with the time of outputting radio frequency energy by the corresponding radio frequency electrode group.

[0077] The middle region of the non-invasive radio frequency treatment head can be provided with an ultrasonic emission window for emitting ultrasonic energy to the target region, the focused ultrasonic signal and the radio frequency energy act on the same region, and the ultrasonic energy and the radio frequency energy act on the subcutaneous tissue at the same time, that is, the time of emitting the ultrasonic energy at least partially overlaps with the time of outputting radio frequency energy by the corresponding radio frequency electrode group, and the effects can be coordinated.

[0078] Referring to Figure 8 As shown in the drawings, the application further provides a non-invasive radio frequency treatment instrument, comprising:

[0079] The non-invasive radio frequency treatment head as disclosed above;

[0080] A treatment handle connected with the non-invasive radio frequency treatment head.

[0081] In the embodiment, the non-invasive radio frequency treatment instrument comprises the non-invasive radio frequency treatment head as disclosed above, and the non-invasive radio frequency treatment head specifically performs radio frequency treatment on the target region in a hand stamping manner. The treatment surface of the non-invasive radio frequency treatment head is provided with a plurality of pairs of radio frequency electrode groups, the plurality of pairs of radio frequency electrode groups comprise at least two pairs of target radio frequency electrode groups, the center positions of the target radio frequency electrode groups overlap, and the distribution form of the target radio frequency electrode groups is determined based on a preset focused treatment depth. The driving mode of the plurality of pairs of radio frequency electrode groups for outputting radio frequency energy to the target region is an alternating driving mode. Each pair of radio frequency electrode groups comprises a first radio frequency electrode and a second radio frequency electrode which are opposite in polarity. In this way, the deep region at the center position receives more radio frequency energy than the deep regions at other positions, and the radio frequency energy can be focused on the same position, so that focused radio frequency treatment can be performed on the target region, that is, non-invasive focused radio frequency treatment can be performed on the deep tissue. Because the different pairs of radio frequency electrode groups are located at different epidermal positions, the epidermis close to the electrodes will be damaged due to the radio frequency treatment. Therefore, the driving mode of the plurality of pairs of radio frequency electrode groups for outputting radio frequency energy to the target region is an alternating and cyclic driving mode, for example, a sequential alternating and cyclic driving mode or an interval alternating and cyclic driving mode, which can avoid the same epidermal position being damaged by radio frequency all the time, and can minimize the damage to the epidermis. The driving mode can also avoid magnetic field disorder caused by the plurality of pairs of electrode groups simultaneously outputting radio frequency energy. The non-invasive radio frequency treatment instrument further comprises a treatment handle for connecting with the non-invasive radio frequency treatment head.

[0082] Further, the distribution form of each pair of target radio frequency electrode groups can be determined based on the preset focused treatment depth. If the preset focused treatment depth is a single depth, the distribution form of each pair of target radio frequency electrode groups is a single-layer distribution form, such as any one of a single-layer regular polygon distribution form, a single-layer circular ring arc distribution form, and a single-layer X-shaped distribution form. If the preset focused treatment depth is a multiple depth, the distribution form of each pair of target radio frequency electrode groups is a multi-layer distribution form, such as any one of a multi-layer circular ring arc distribution form, a multi-layer elliptical arc distribution form, a multi-layer rectangular distribution form, a multi-layer single-row distribution form, and a multi-layer double-row distribution form.

[0083] The middle region of the non-invasive radio frequency treatment head can contain various devices according to specific conditions, and specifically can include a cooling module. The first cooling module includes a cold spray device and a heat uniformizing sheet. The second cooling module includes a semiconductor refrigerator and a heat conducting sheet.

[0084] The middle region of the non-invasive radio frequency treatment head includes a heating sheet, which is used for preheating and thermal stimulation of the target region.

[0085] Further, the middle region of the non-invasive radio frequency treatment head further includes a contact sensor, a temperature sensor, a displacement sensor, a monopolar radio frequency electrode, and an ultrasonic emission window. It should be noted that the radio frequency energy output time of the monopolar radio frequency electrode is different from the radio frequency energy output time of each pair of radio frequency electrode groups, and the ultrasonic energy emission time at least partially overlaps the radio frequency energy output time of the corresponding radio frequency electrode group.

[0086] Referring to Figure 9 As shown in the drawings, the embodiments of the present application disclose a non-invasive radio frequency treatment head control method. The non-invasive radio frequency treatment head includes a plurality of pairs of radio frequency electrode groups, and the plurality of pairs of radio frequency electrode groups include at least two pairs of target radio frequency electrode groups. The center positions of the target radio frequency electrode groups overlap, and the distribution form of the target radio frequency electrode groups is determined based on a preset focused treatment depth. Each pair of radio frequency electrode groups includes a first radio frequency electrode and a second radio frequency electrode with opposite polarities. The non-invasive radio frequency treatment head control method includes the following steps.

[0087] Step S11: determining a current radio frequency electrode group from the target radio frequency electrode groups based on an alternating driving mode.

[0088] In this embodiment, the alternate driving mode includes sequential alternate driving, interval alternate driving and random alternate driving. It can be understood that the alternate driving mode includes sequential alternate driving, interval alternate driving and random alternate driving. In a specific embodiment, a driving mode determination instruction issued by a user can be received through a preset interface. The driving mode determination instruction can be used to not only indicate whether the driving mode is an alternate driving mode, but also determine the driving mode corresponding to the driving mode determination instruction from the sequential alternate driving, interval alternate driving and random alternate driving. If the alternate driving mode is sequential alternate driving, each pair of target radio frequency electrode groups is sequentially taken as the current radio frequency electrode group based on a preset radio frequency electrode group sequence. If the alternate driving mode is interval alternate driving, each pair of radio frequency electrode groups is taken as the current radio frequency electrode group based on a preset radio frequency electrode group sequence. If the alternate driving mode is random alternate driving, each pair of radio frequency electrode groups is randomly taken as the current radio frequency electrode group.

[0089] Step S12: controlling the current radio frequency electrode group to output radio frequency energy to the action area, and controlling the previous radio frequency electrode group to stop outputting radio frequency energy; wherein the center of the action area of the previous radio frequency electrode group overlaps with the center of the action area of the current radio frequency electrode group.

[0090] In this embodiment, in order to avoid magnetic field interference caused by multiple pairs of radio frequency electrode groups simultaneously outputting radio frequency energy and reduce damage to the epidermis, the previous radio frequency electrode group stops outputting radio frequency energy when the current radio frequency electrode group outputs radio frequency energy to the action area. That is, only one pair of target radio frequency electrode groups can output radio frequency energy to the action area. When only one pair of electrodes outputs radio frequency energy, it follows the conventional bipolar radio frequency output characteristics, that is, the current density is highest near the electrodes, and the epidermal tissue heating effect is also the best. The heating effect of the deep tissue corresponding to the center position is not as good as that of the epidermal tissue. However, during a round of treatment cycle, the tissues at the deep part near the center position will be heated multiple times compared to the epidermal tissues near the electrodes, so as to achieve the treatment effect of focused radio frequency.

[0091] Further, the distribution form of the target radio frequency electrode group can be determined based on a preset focused treatment depth. If the preset focused treatment depth is a single depth, the distribution form of each pair of target radio frequency electrode groups is a single-layer distribution form, such as any one of a single-layer regular polygon distribution form, a single-layer circular ring arc distribution form, and a single-layer X-shaped distribution form. If the preset focused treatment depth is a multiple depth, the distribution form of each pair of target radio frequency electrode groups is a multi-layer distribution form, such as any one of a multi-layer circular ring arc distribution form, a multi-layer elliptical arc distribution form, a multi-layer rectangular distribution form, a multi-layer single-row distribution form, and a multi-layer double-row distribution form.

[0092] The middle region of the non-invasive radio frequency treatment head can contain various devices according to specific circumstances, which can specifically include a cooling module, the first cooling module including a cold spray device and a heat uniformizing sheet, and the second cooling module including a semiconductor refrigerator and a heat conducting sheet. Alternatively, the middle region of the non-invasive radio frequency treatment head includes a heating sheet for preheating and thermal stimulation of the target region. Further, the middle region of the non-invasive radio frequency treatment head also includes a contact sensor, a temperature sensor, a displacement sensor, a monopolar radio frequency electrode, and an ultrasonic emission window. It should be noted that the radio frequency energy output time of the monopolar radio frequency electrode is different from the radio frequency energy output time of each pair of radio frequency electrode groups, and the time of emitting ultrasonic energy at least partially overlaps with the radio frequency energy output time of the corresponding radio frequency electrode group.

[0093] As can be seen, the target radio frequency electrode group of the present application is distributed on the treatment surface of the non-invasive radio frequency treatment head body based on the preset focusing treatment depth, that is, the radio frequency energy output by the target radio frequency electrode group can reach different preset focusing treatment depths. Since the center positions of each pair of target radio frequency electrode groups overlap, the radio frequency electrode positions of different target radio frequency electrode groups are different, but the radio frequency energy they output alternately will all pass through the deep region corresponding to the center position, but will not repeatedly output radio frequency energy to other positions except the center position. Therefore, the deep region of the center position receives more radio frequency energy than the deep region of other positions, resulting in more cumulative radio frequency energy, which can focus radio frequency energy at the same position and perform focused radio frequency treatment on the action region, that is, non-invasive focused radio frequency treatment of deep tissue is achieved. Further, if there are multiple pairs of radio frequency electrode groups outputting radio frequency energy at the same time, the distribution of positive and negative electrodes is very chaotic, which will preferentially form teams of the closest positive and negative electrodes, resulting in few current passing through the central region. Therefore, the driving mode of the multiple pairs of radio frequency electrode groups of the present application for outputting radio frequency energy to the target region is an alternating driving mode, that is, the present application does not allow all radio frequency electrode groups to output radio frequency energy at the same time, which ensures that the radio frequency energy can accurately pass through the action region, avoids interference from other electrodes, and also reduces damage to the epidermis.
