[0004] With the rapid development of the medical aesthetics industry, an increasing number of new treatment technologies are being applied in the field, such as radiofrequency therapy, EMS (Electric Muscle Stimulation), and laser therapy. Radiofrequency and electrical stimulation can stimulate local collagen production and accelerate skin metabolism, thereby reducing acne scars, dark spots, and wrinkles, resulting in smoother and more refined skin. Therefore, these technologies have become a hot topic in the medical aesthetics industry.

[0005] Existing radio frequency or EMS treatments generally use radio frequency or EMS transmitting electrodes set on electrode sheets. During treatment, radio frequency energy is transmitted between two radio frequency electrodes of different polarities. Because radio frequency energy is affected by the distance between the electrodes, existing electrode sheets have uneven energy density and cannot achieve the expected treatment effect.

[0038] The present application proposes a flexible electrode sheet 1 .

[0039] As shown in Figures 1 and 3, in one embodiment of the present application, the flexible electrode sheet 1 includes a substrate 10, a radio frequency zone 20 and an electrical stimulation zone 30; the radio frequency zone 20 is provided with at least one radio frequency electrode to generate radio frequency energy, and the radio frequency zone 20 is also provided with a through groove in areas other than the radio frequency electrode; the electrical stimulation zone 30 is provided with at least one electrical stimulation electrode, and the electrical stimulation electrode is electrically connected to an external power supply to generate microcurrent; the radio frequency zone 20 and the electrical stimulation zone 30 are independently arranged on the substrate 10.

[0040] In this embodiment, the flexible electrode sheet 1 includes a radio frequency zone 20 and an electrical stimulation zone 30, which are used to transmit radio frequency signals and microcurrent signals to achieve the purpose of cosmetic treatment. The shape of the flexible electrode sheet 1 matches the shape of the skin so that it can fit the skin. The flexible electrode sheet 1 can be suitable for cosmetic treatment of skin in areas such as the cheeks, corners of the eyes, forehead, and chin. The flexible electrode sheet 1 includes a base 10, which can be a flexible circuit board, and the radio frequency zone 20 and the electrical stimulation zone 30 are arranged on the base 10. The base 10 needs to have insulation and flexibility so that it can fit the skin. The radio frequency zone 20 includes at least one radio frequency electrode, which is arranged at intervals and electrically connected to an external power supply. Radio frequency energy is transmitted between radio frequency electrodes of different polarities, thereby playing a role in treating the skin. At the same time, a groove 13a is provided at the end of the flexible electrode sheet 1 away from the gripping portion 11 to avoid the position of the eyeball and prevent the radio frequency or electrical stimulation energy emitted by the electrode from causing damage to the eyeball. The electrical stimulation area 30 is provided with electrical stimulation electrodes of different polarities and is electrically connected to an external power source. By providing the electrical stimulation electrodes, microcurrents are generated between the electrical stimulation electrodes of different polarities, thereby achieving a skin treatment effect.

[0041] The flexible electrode sheet 1 proposed in this application arranges multiple radio frequency electrodes in sequence at intervals, and the radio frequency electrodes have different polarities, so that the transmission distance of radio frequency energy between radio frequency electrodes of different polarities is shorter, so that the energy density is more uniform, which solves the problem of uneven energy density during treatment in existing therapeutic devices and improves the treatment effect.

[0042] Please continue to refer to FIG. 1 and FIG. 3 . In one embodiment of the present application, a plurality of radio frequency electrodes are provided and are sequentially spaced apart. The polarities of two adjacent radio frequency electrodes are different.

[0043] In this embodiment, multiple RF electrodes are arranged in sequence and spaced apart, and the polarities of two adjacent RF electrodes are different. RF energy can be transmitted between every two adjacent RF electrodes, further shortening the transmission distance between RF electrodes of different polarities, thereby further improving the uniformity of energy density.

[0044] Continuing to refer to Figures 1 and 3, in one embodiment of the present application, the RF electrode includes a first RF electrode 21 and a second RF electrode 22 of different polarities. The first RF electrode 21 includes a plurality of first fins 211, each connected to a first connecting portion 212. The second RF electrode 22 includes a plurality of second fins 221, each connected to a second connecting portion 222. The first connecting portion 212 is located on one side of the flexible electrode sheet 1, and the second connecting portion 222 is located on the other side of the flexible electrode sheet 1. The first connecting portion 212 and the second connecting portion 222 enclose a RF region 20. The plurality of first fins 211 and the plurality of second fins 221 are both located within the RF region 20. The first connecting portion 212 and the second connecting portion 222 serve as circuit lines for providing RF electrical signals to the first and second RF electrodes 21 and 22.

[0045] In this embodiment, the first and second RF electrodes 21, 22 transmit RF energy, which is focused on the skin to provide a cosmetic treatment. The first and second RF electrodes 21, 22 have different polarities. When energized, an RF energy field forms between them, causing frictional movement of molecules within the tissue and accumulating heat within the dermis. This promotes the contraction of existing collagen and the production of new collagen, achieving cosmetic effects such as skin tightening, wrinkle reduction, and lifting.

[0046] The first RF electrode 21 includes a first fin 211 connected to a first connecting portion 212. The first connecting portion 212 is located on one side of the flexible electrode sheet 1 and extends parallel to the side of the flexible electrode sheet 1 to increase the range of RF energy applied to the multiple first fins 211 in the first RF electrode 21. The second RF electrode 22 includes a second fin 221 connected to a second connecting portion 222. The second connecting portion 222 is located on the other side of the flexible electrode sheet 1 and extends parallel to the other side of the flexible electrode sheet 1 to increase the range of RF energy applied to the multiple second fins 211 in the second RF electrode 22. The first fin 211 and the second fin 221 are located within the RF zone 20 enclosed by the first connecting portion 212 and the second connecting portion 222. The provision of the first fin 211 and the second fin 221 increases the range of RF energy applied to the flexible electrode sheet 1, further enhancing the effectiveness of the cosmetic treatment.

[0047] 1 and 3 , in one embodiment of the present application, a plurality of first fins 211 extend from the first connection portion 212 toward the second connection portion 222 , and a plurality of second fins 221 extend from the second connection portion 222 toward the first connection portion 212 , wherein the first connection portion 212 and the second connection portion 222 both serve as circuit lines for providing radio frequency electrical signals to the first radio frequency electrode 21 and the second radio frequency electrode 22 .

[0048] In this embodiment, one end of the first fin 211 is connected to one side of the first connecting portion 212, and the other end extends toward the second connecting portion 222. One end of the second fin 221 is connected to one side of the second connecting portion 222, and the other end extends toward the first connecting portion 212. Both the first connecting portion 212 and the second connecting portion 222 are extended, expanding the range of the radio frequency zone, increasing the effective range of the radio frequency energy in the flexible electrode sheet 1, and enhancing the cosmetic effect.

[0049] Please continue to refer to Figures 1 and 3. In one embodiment of the present application, a plurality of first fins 211 are arranged at intervals along the direction in which the first connecting portion 212 extends, and a plurality of second fins 221 are arranged at intervals along the direction in which the second connecting portion 222 extends. The plurality of first fins 211 and the plurality of second fins 221 are alternately arranged, and a through groove is provided in the area between each adjacent first fin 211 and second fin 221.

[0050] In one embodiment, a plurality of through slots are provided, and each through slot is extended along the extending direction of the first fin and the second fin.

[0051] In this embodiment, a plurality of first fins 211 are provided on the first radio frequency electrode 21, and a plurality of second fins 221 are provided on the second radio frequency electrode 22, so that the effective area of ​​the radio frequency energy can be increased so as to facilitate the treatment of a larger area of ​​the skin. The plurality of first fins 211 and the plurality of second fins 221 are arranged alternately. Each first fin 211 and each second fin 221 have different polarities, so that an alternating electromagnetic field is formed in the skin area between the first fin 211 and the second fin 221, and the area is treated. By providing a plurality of first fins 211 and a second fin 221, a plurality of electromagnetic field loops with uniform energy are formed in the radio frequency zone 20, so that radio frequency treatment can be carried out on different areas of the skin in a targeted manner, thereby improving the treatment effect and convenience. At the same time, the plurality of first fins 211 and the plurality of second fins 221 are arranged at intervals in the radio frequency zone 20 enclosed by the first connecting portion 212 and the second connecting portion 222, and are extended. The first RF electrode 21 and the second RF electrode 22 are configured to consist of a plurality of first fins 211 and second fins 221 arranged at intervals, so that a larger RF action range is divided into a plurality of smaller RF action ranges, making the energy density in the RF zone 20 more uniform, so as to further improve the treatment effect.

[0052] Continuing with Figures 1 and 3 , in one embodiment of the present application, the width of the first fin 211 and the second fin 221 is 1 to 5 mm, and the distance between adjacent first fins 211 and second fins 221 is 2 to 8 mm. The width of the through-slots is 1 to 7 mm. When the width or spacing between adjacent first fins 211 and second fins 221 is small, the RF energy is concentrated in one spot, easily causing skin burns. When the width or spacing between adjacent first fins 211 and second fins 221 is large, the RF energy is uneven, resulting in poor cosmetic treatment results. Therefore, the width of the first fin 211 and second fin 221 is set to 1 to 5 mm, the spacing between adjacent first fins 211 and second fins 221 is 2 to 8 mm, and the width of the through-slots is 1 to 7 mm. This arrangement leverages the edge effect of the RF electrode, creating a closer distance between the edges of the through-slots, where the electrode energy is higher, and the center of the fins, where the energy is lower, so that the corresponding areas of skin receiving high and low energy are closer together. Due to the short distance, heat conduction is faster, making the temperature applied to the tissue by each first fin 211 and second fin 221 more uniform, thereby further improving the uniformity of the RF energy density and enhancing the therapeutic effect. In other embodiments, the first fin 211 and second fin 221 can be designed in a spiral, I-shaped, or lattice shape, and the through-grooves formed between the first fin 211 and second fin 221 can also be designed in a spiral, I-shaped, or lattice shape. This can effectively utilize the edge effect of the RF current and improve the uniformity of the RF energy.

[0053] Please continue to refer to Figures 1 and 3. In one embodiment of the present application, the flexible electrode sheet 1 further includes a temperature detection element 40. There is at least one temperature detection element 40, which is disposed on the surface of the RF electrode in the higher temperature area of ​​the RF zone 20 to detect the temperature of the skin in the treatment area.

[0054] In this embodiment, the temperature detection element 40 may be a thermistor, positioned at the location with the highest temperature within the RF zone 20. The location of the highest temperature can be determined through experimental testing. For example, the flexible electrode sheet 1 is first placed against the test skin. After the flexible electrode sheet 1 is energized, the radiofrequency electric field generated between the radiofrequency electrodes acts on the skin. Molecules within the skin tissue undergo frictional motion under the action of the radiofrequency electric field, causing the skin temperature to rise. Heat is then conducted through the skin to the surface of the radiofrequency electrode. The location of the highest temperature point on the flexible electrode sheet 1 is determined using the temperature detector 40, and the temperature detection element 40 is positioned at the corresponding location. The temperature detection element 40 is positioned on the surface of the radiofrequency electrode in the higher temperature area of ​​the radiofrequency zone 20 and electrically connected to an external power source. When the temperature is too high, the resistance of the thermistor increases and is fed back to the external host. The host then blocks electrical communication with the radiofrequency electrode to prevent skin burns caused by excessive temperature. It is understood that the temperature detection element 40 should be positioned at the location where the radiofrequency electrode temperature is higher to more accurately detect the temperature of the flexible electrode sheet 1 and avoid skin burns caused by excessive temperature. When setting the temperature detection element 40, a thermometer can be used to detect the position of the highest temperature point of the flexible electrode sheet 1, and the temperature detection element 40 can be set at the corresponding position. In other embodiments, the temperature detection element 40 can also be a temperature sensor.

[0055] In one embodiment of the present application, an adhesive is provided on the surface of the radio frequency zone 20 to enable the radio frequency electrode to adhere to the skin.

[0056] In this embodiment, an adhesive member is provided on the surface of the RF region 20, which is formed by the first connecting portion 212 and the second connecting portion 222. In one embodiment, the adhesive member can be a pad, gel, or the like, which has good adhesion and a certain degree of flexibility, so that the RF electrode can better adhere to the skin and improve the convenience of treatment.

[0057] As shown in conjunction with FIG1 and FIG3 , in one embodiment of the present application, the electrical stimulation electrode includes a first electrical stimulation electrode 31 and a second electrical stimulation electrode 32 with different polarities, and the first electrical stimulation electrode 31 and the second electrical stimulation electrode 32 are arranged at intervals.

[0058] In this embodiment, the first and second electrical stimulation electrodes 31, 32 function by stimulating the subcutaneous muscle layer through a microcurrent emitted by an electrostimulation (EMS) electrode, thereby achieving a therapeutic effect on the skin. Normally, muscles begin to move actively after receiving signals from the brain. However, EMS technology transmits these signals directly to the muscles through electrical stimulation, prompting them to perform passive, high-frequency movements. Under high-frequency movement, muscles can consume 3,000 to 4,000 joules per second of energy, thereby depleting excess fat, sugar, and carbohydrates in the surrounding tissue. Simultaneously, it stimulates the dermis, promoting collagen synthesis in cells, tightening contours, and refining the skin. The first and second electrical stimulation electrodes 31, 32 have different polarities, allowing the microcurrent signal to propagate between them. The second electrical stimulation electrode 32 is located outside the middle portion of the second connecting portion 222. The second connecting portion 222 is bent near the end, forming a clearance zone on the base 10. The first electrical stimulation electrode 31 is located within the clearance zone. The first electrical stimulation electrode 31 is set on the outside near the end of the second connecting portion 222 to facilitate the treatment of the masseter muscles of the face. The second electrical stimulation electrode 32 is set on one side of the middle part of the second connecting portion 222 to facilitate the treatment of the apple muscles of the face, that is, the zygomatic fat. At the same time, the shape of the first electrical stimulation electrode 31 can be designed to be the same as or similar to the shape of the masseter muscles, and the shape of the second electrical stimulation electrode 32 can be designed to be the same as or similar to the shape of the zygomatic fat, so as to improve the targeted treatment effect of the electrical stimulation electrodes on the facial muscles. In other embodiments, the first electrical stimulation electrode 31 and the second electrical stimulation electrode 32 can also be set at other positions of the base 10 to correspond to the treatment of muscles or tissues in other positions of the skin.

[0059] In one embodiment of the present application, the surfaces of the first electrical stimulation electrode 31 and the second electrical stimulation electrode 32 are both provided with a fitting member so that the electrical stimulation electrodes fit the skin and conduct microcurrent;

[0060] And / or, a gripping portion 11 is provided at one end of the flexible electrode sheet 1 , and a connection position 12 is provided at one end of the gripping portion 11 away from the flexible electrode sheet 1 , and the radio frequency electrode and the electrical stimulation electrode are electrically connected to the external control terminal via the connection position 12 .

[0061] In this embodiment, the fitting may be a conductive gel, and conductive gel is provided on the surface of the first electrical stimulation electrode 31 and the second electrical stimulation electrode 32. The conductive gel ensures the transmission of microcurrent between the electrical stimulation electrodes. At the same time, the conductive gel has good flexibility and viscosity, so that the flexible electrode sheet 1 can better fit the skin, further improving the treatment effect.

[0062] In cases where a fitting is provided on the surface of the electrostimulation electrode, or not, a grip portion 11 provided at one end of the flexible electrode sheet 1 is used to hold the flexible electrode sheet 1 when it is placed against the face, thereby improving the convenience of operation for medical personnel. The grip portion 11 can be formed by a protrusion at the end of the flexible electrode sheet 1. A connection point 12 is provided at the end of the grip portion 11 away from the flexible electrode sheet 1. The connection point 12 is electrically connected to an external power source to provide power to the radiofrequency electrode and the electrostimulation electrode.

[0063] The flexible electrode sheet 1 also includes a position detection element (not shown). The flexible electrode sheet 1 comes in a variety of shapes and can be configured as two mirror-symmetrical flexible electrode sheets 1, facilitating simultaneous treatment of the left and right sides of the face. The position detection element is electrically connected to an external host. Once the flexible electrode sheet 1 is connected to the host's interface, the host can automatically determine the type of flexible electrode sheet 1 by detecting the properties of the position detection element and supply power based on the set electrode properties, further enhancing operational convenience.

[0064] This application also provides a therapeutic device (not shown), which includes a main unit and a flexible electrode sheet 1. The main unit is electrically connected to the flexible electrode sheet 1 and controls the flexible electrode sheet 1 to generate radiofrequency energy and microcurrent. The specific structure of the flexible electrode sheet 1 is similar to the above-mentioned embodiments. Since this therapeutic device adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be detailed here.

[0065] In this embodiment, the host computer is electrically connected to the flexible electrode sheet 1, providing power for the electrodes. The host computer is also in communication with the flexible electrode sheet 1, enabling control of the electrode polarity, adjustment of parameters such as the RF frequency, RF power, and electrical stimulation current, and display of the flexible electrode sheet 1's operating status and parameters, thereby enhancing operational convenience for medical personnel.

[0066] In one embodiment of the present application, two flexible electrode sheets are provided and are both electrically connected to the host, the radio frequency electrodes of one flexible electrode sheet are both positive electrodes, and the radio frequency electrodes of the other flexible electrode sheet are both negative electrodes;

[0067] And / or, there are two flexible electrode sheets, and both are electrically connected to the host, the electrical stimulation electrodes of one flexible electrode sheet are both positive electrodes, and the electrical stimulation electrodes of the other flexible electrode sheet are both negative electrodes.

[0068] In this embodiment, two flexible electrode sheets are provided, each electrically connected to the host device. The polarity of the radio frequency electrodes in a single flexible electrode sheet (1) is the same: the radio frequency electrodes in one flexible electrode sheet (1) are all positive, while the radio frequency electrodes in the other flexible electrode sheet (1) are all negative. The radio frequency electromagnetic field propagates through one flexible electrode sheet (1) to the other, achieving the effect of simultaneously treating the skin on both the left and right sides of the face.

[0069] With or without limiting the polarity of the radio frequency electrodes of the two flexible electrode sheets 1, the polarity of the electrical stimulation electrodes in the same flexible electrode sheet 1 is the same, with the electrical stimulation electrodes of one flexible electrode sheet 1 all being positive and the electrical stimulation electrodes of the other flexible electrode sheet 1 all being negative. The microcurrent is transmitted through one flexible electrode sheet 1 to the other flexible electrode sheet 1, thereby achieving the effect of simultaneously treating the left and right sides of the face.

[0070] In other embodiments, the polarities of the multiple RF electrodes in each flexible electrode sheet 1 are different, the polarities of the electrical stimulation electrodes in each flexible electrode sheet 1 are different, and the RF energy and microcurrent are transmitted between the multiple RF electrodes and the multiple electrical stimulation electrodes provided on each flexible electrode sheet 1.

[0071] The present application proposes a flexible electrode sheet 1 .

[0072] As shown in Figures 5 to 8, in one embodiment of the present application, the flexible electrode sheet 1 includes a radio frequency zone 20 and an electrical stimulation zone 30; the radio frequency zone 20 is provided with a plurality of radio frequency electrodes with different polarities, and the plurality of radio frequency electrodes are electrically connected to an external power supply to generate radio frequency energy, and a through groove 15a is provided between the radio frequency electrodes; the electrical stimulation zone 30 is provided with electrical stimulation electrodes with different polarities, and the electrical stimulation electrodes are electrically connected to an external power supply to generate microcurrent; the radio frequency zone 20 and the electrical stimulation zone 30 are both attached to the skin.

[0073] In this embodiment, the flexible electrode sheet 1 further includes a substrate 10, on which the radio frequency zone 20 and the electrical stimulation zone 30 are both disposed. The substrate 10 may be a flexible circuit board made of materials such as PI (polyimide), PET (polyester), or PEN (polyethylene terephthalate), and may have a certain degree of flexibility to improve the fit between the flexible electrode sheet 1 and the skin. The shape of the flexible electrode sheet 1 matches the shape of the skin, further improving the fit between the flexible electrode sheet 1 and the skin. The radio frequency zone 20 is provided with a plurality of radio frequency electrodes of different polarities, and radio frequency signals are transmitted between the radio frequency electrodes of different polarities, thereby achieving a therapeutic effect on the skin. The electrical stimulation zone 30 is provided with electrical stimulation electrodes of different polarities and is electrically connected to an external power source. By providing the electrical stimulation electrodes, microcurrents are generated between the electrical stimulation electrodes of different polarities, thereby achieving a therapeutic effect on the skin. By providing a through groove 15a between the radio frequency electrodes, with both ends of the through groove 15a being continuous, the overall flexibility of the flexible electrode sheet 1 can be increased, further improving the fit between the flexible electrode sheet 1 and the skin.

[0074] The flexible electrode sheet 1 proposed in the present application further improves the flexibility of the flexible electrode sheet 1 by designing the shape of the flexible electrode sheet 1 to match the shape of the skin, using flexible materials to improve flexibility, and providing through grooves 15a between the radio frequency electrodes, thereby making the flexible electrode sheet 1 easier to bend to match the shape of the skin, thereby improving the fit of the flexible electrode sheet 1 to the human face, reducing the possibility of poor treatment effect due to poor fit or skin burns due to concentrated heat, and improving the treatment effect of the flexible electrode sheet 1.

[0075] 5 to 8 , a plurality of through slots 15 a are provided, and the plurality of through slots 15 a are all extended along the direction in which the RF electrodes extend.

[0076] In this embodiment, a plurality of through-grooves 15a are provided, each of which is disposed between two adjacent RF electrodes and extends in the direction in which the RF electrodes extend. By providing a plurality of through-grooves 15a between the RF electrodes, the flexibility of the flexible electrode sheet 1 is further improved, making it easier for the flexible electrode sheet 1 to adhere to the skin. The bones and muscles of the skin can cause the skin surface to be uneven. By providing a plurality of through-grooves 15a within the RF zone 20 and arranging them in sequence at intervals perpendicular to the RF electrodes, the flexible electrode sheet 1 has good flexibility at different positions, thereby improving the overall flexibility of the flexible electrode sheet 1 and improving the adherence of the flexible electrode sheet 1 to the skin.

[0077] As shown in conjunction with FIG5 and FIG7 , in one embodiment of the present application, the radio frequency electrode includes a first radio frequency electrode 21 and a second radio frequency electrode 22 ;

[0078] The first RF electrode 21 includes a plurality of first fins 211 connected to the first connecting portion 212, and the second RF electrode 22 includes a second fin 221 connected to the second connecting portion 222. The first connecting portion 212 is located on one side of the mounting surface, and the second connecting portion 222 is located on the other side of the mounting surface. The first connecting portion 212 and the second connecting portion 222 enclose a RF working area. A plurality of first fins 211 are provided, and the plurality of first fins 211 are provided in the RF working area and are arranged at intervals along the direction in which the first connecting portion 212 extends. A plurality of second fins 221 are provided, and the plurality of second fins 221 are provided in the RF working area and are arranged at intervals along the direction in which the second connecting portion 222 extends. The plurality of first fins 211 and the plurality of second fins 221 are arranged alternately. A first fin 211 and a second fin 221 are provided on both sides of each through slot 15a, respectively. The through slot 15a extends along the direction in which the first fin 211 or the second fin 221 extends.

[0079] In this embodiment, the first and second RF electrodes 21, 22 have different polarities. When the RF electrodes are energized, an electromagnetic field is formed between the first and second RF electrodes 21, 22, causing frictional movement of molecules within the tissue and accumulating heat within the dermis, promoting the contraction of existing collagen and the production of new collagen, thereby achieving cosmetic effects such as skin tightening, wrinkle reduction, and lifting. A first connecting portion 212 is provided on one side of the flexible electrode sheet 1, and a second connecting portion 222 is provided on the other side of the flexible electrode sheet 1. Both the first and second connecting portions 212, 222 extend from one end of the flexible electrode sheet 1 to the other end to increase the range of RF energy. A plurality of first fins 211 extend from one side of the first RF electrode 21. A plurality of second fins 221 extend from one side of the second RF electrode 22. The first fin 211 and the second fin 221 are disposed within the RF region 20 enclosed by the first connecting portion 212 and the second connecting portion 222. The provision of the first fin 211 and the second fin 221 increases the range of action of the RF energy of the flexible electrode sheet 1, further improving the efficiency of the cosmetic treatment. The plurality of first fins 211 and the plurality of second fins 221 are alternately disposed, each first fin 211 and each second fin 221 having different polarities. A RF electromagnetic field is formed between the first fin 211 and the second fin 221, thereby treating the area. A first fin 211 and a second fin 221 are provided on either side of each through-slot 15a, respectively. The through-slot 15a limits the distance between the first fin 211 and the second fin 221, thereby ensuring that each interacting first fin 211 and second fin 221 can better adhere to the skin. By providing multiple first fins 211 and second fins 221, radiofrequency treatment can be targeted to different areas of the skin, improving treatment efficiency and convenience. The through-slots 15a extend in the same direction as the first fins 211 or the second fins 221, further improving the fit of each interacting first fin 211 and second fin 221 to the skin, enhancing the treatment effect. An adhesive member is also provided on the surface of the radiofrequency working area. The adhesive member may be a pad, gel, or the like, with a certain degree of stickiness and flexibility, allowing the radiofrequency electrode to better fit the skin and improving the convenience of treatment.

[0080] 5 and 7 , in one embodiment of the present application, the width of the through slot 15 a is 1 to 7 mm, and the width of the first fin 211 and the second fin 221 is 1 to 5 mm.

[0081] The depth of the dermis is approximately 3 mm, and the energy focusing depth of the RF electrode is approximately half the electrode distance. Therefore, in this embodiment, the width of the through-slot 15a is designed to be 1 to 7 mm, and the width of the first fin 211 and the second fin 221 is 1 to 5 mm. The first fin 211 and the second fin 221 are respectively arranged on either side of the through-slot 15a. Therefore, the RF energy can be focused on the dermis to achieve a cosmetic effect. When the width of the through-slot 15a is too large and the widths of the first fin 211 and the second fin 221 are small, the distance between the first fin 211 and the second fin 221 is large, resulting in a large focusing depth of the RF energy, exceeding the dermis. When the width of the through-slot 15a is small and the widths of the first fin 211 and the second fin 221 are large, the distance between the first fin 211 and the second fin 221 is close, and the RF energy is focused on the epidermis, failing to achieve a cosmetic effect.

[0082] At the same time, the width settings of the through-slot 15a, the first fin 211, and the second fin 221 can utilize the edge effect to improve the uniformity of the radio frequency energy. Because the first fin 211 and the second fin 221 are respectively arranged on both sides of the through-slot 15a, the high energy at the edge of the flexible electrode sheet 1 and the low energy at the center are closer, so that the positions where the skin receives high energy and low energy are closer. Due to the short distance, the heat conduction is faster, so that the temperature of each first fin 211 and the second fin 221 acting on the tissue is more uniform. Thereby, the uniformity of radio frequency treatment is improved. The focusing depth of radio frequency energy is also related to the frequency. Therefore, in other embodiments, when the distance between the electrodes is large, the frequency can also be adjusted to achieve the purpose of treatment by focusing the radio frequency energy on the dermis.

[0083] Please continue to refer to Figures 5 and 7. In one embodiment of the present application, the electrical stimulation electrode includes a first electrical stimulation electrode 31 and a second electrical stimulation electrode 32 with different polarities, and the first electrical stimulation electrode 31 and the second electrical stimulation electrode 32 are arranged at intervals.

[0084] In this embodiment, the first and second electrostimulation electrodes 31, 32 function by stimulating the skin's muscle layer with a microcurrent emitted by an electrostimulation (EMS) electrode, thereby achieving a therapeutic effect. EMS technology uses electrical stimulation to directly transmit signals to the muscles, prompting them to engage in passive high-frequency movements, thereby depleting excess fat, sugar, and carbohydrates in the surrounding tissue. It also stimulates the dermis, promoting collagen synthesis in cells, tightening contours, and refining the skin. The first and second electrostimulation electrodes 31, 32 have different polarities to facilitate microcurrent signal propagation between them. The first and second electrostimulation electrodes 31, 32 are spaced apart. For example, the second electrostimulation electrode 32 can be positioned in the middle of the second connecting portion 222, facing away from the radiofrequency zone 20. The second connecting portion 222 is bent near the end, forming a clearance zone on the flexible electrode sheet 1. The first electrostimulation electrode 31 is positioned within the clearance zone. Positioning the first electrostimulation electrode 31 at the end of the second connecting portion 222, facing away from the radiofrequency zone 20, facilitates treatment of the masseter muscles of the skin. The second electrical stimulation electrode 32 is set on one side of the middle part of the second connecting part 222 to facilitate the treatment of the apple muscles of the skin, that is, the zygomatic fat. At the same time, the shape of the first electrical stimulation electrode 31 can be designed to be the same as or similar to the shape of the masseter muscle, and the shape of the second electrical stimulation electrode 32 can be designed to be the same as or similar to the shape of the zygomatic fat, so as to improve the targeted treatment effect of the electrical stimulation electrode on the skin muscles. In other embodiments, the first electrical stimulation electrode 31 and the second electrical stimulation electrode 32 can also be set at other positions of the flexible electrode sheet 1 to correspond to the treatment of muscles or tissues in other positions of the skin. Conductive gel is also provided on the surface of the first electrical stimulation electrode 31 and the second electrical stimulation electrode 32. The conductive gel ensures the transmission of microcurrent between the electrical stimulation electrodes. At the same time, the conductive gel has good flexibility and viscosity, so that the flexible electrode sheet 1 can better fit the skin, further improving the treatment effect.

[0085] 5 to 8 , in one embodiment of the present application, a plurality of cutouts 14 a are formed on the periphery of the substrate 10 .

[0086] In this embodiment, the shape of the incision 14a can be triangular, rectangular, or the like. The incision 14a is formed on the outer periphery of the flexible electrode sheet 1. The depth, size, and position of the incision 14a can be designed based on the location of the radiofrequency electrodes and electrical stimulation electrodes on the flexible electrode sheet 1. The incision 14a should avoid the locations of the radiofrequency electrodes and electrical stimulation electrodes. By forming the incision 14a on the outer periphery of the flexible electrode sheet 1, the flexibility of the flexible electrode sheet 1 is improved, further enhancing the fit between the flexible electrode sheet 1 and the skin.

[0087] Please continue to refer to Figures 5 to 8. In one embodiment of the present application, the substrate 10 layer includes a first side 16, a second side 17 and a third side 18. The first side 16 extends from the first end to the second end of the flexible electrode sheet 1. The second side 17 is arranged opposite to the first side 16 and extends from the first end to the second end of the flexible electrode sheet 1. The third side 18 is arranged between an end of the first side 16 facing the first end and an end of the second side 17 facing the first end, and is recessed toward the second end to form an eye-avoidance position.

[0088] The shape of the flexible electrode sheet 1 should be designed to conform to the skin. In this embodiment, the flexible electrode sheet 1 can be designed to fit the face. The first side 16 can be straight, conforming to the side closest to the nose and chin during treatment. The second side 17 can be curved, conforming to the side farther from the nose and chin during treatment. The third side 18 conforms to the area near the eyes during treatment and is recessed toward the second end to form a groove 13a. This groove 13a protects the eyes from the radiofrequency or electrical stimulation energy emitted by the electrode, preventing it from passing through the eyeball and causing damage. The junctions between the first side 16, the second side 17, and the third side 18 are smoothly rounded to prevent sharp edges from scratching the skin. The shape of the flexible electrode sheet 1 matches the shape of the skin, improving its conformability. Furthermore, a circular bump is formed at the end of the first fin 211 near the groove 13a, and a second fin 221 is positioned around the outer periphery of the circular bump to enhance the therapeutic effect of the flexible electrode sheet 1 on the canthus of the eye. The distance between the outermost edges of the radio frequency electrodes and the electrical stimulation electrodes and the edge of the flexible electrode sheet 1 can be as small as possible to increase the treatment range of the flexible electrode sheet 1 .

[0089] In one embodiment of the present application, the flexible electrode sheet 1 further includes a fit detection element (not shown), which is disposed on the surface of the radio frequency electrode or the electrical stimulation electrode to determine the fit between the flexible electrode sheet 1 and the skin.

[0090] In this embodiment, after the flexible electrode sheet 1 is fitted to the skin, a fitting detection element is used to detect whether the fit is good. The fitting detection element can be an impedance detection element. After the flexible electrode sheet 1 is fitted to the skin, the impedance value at both ends of the flexible electrode sheet 1 is detected by the impedance detection element to determine whether the fit is good. When the fit is poor, the impedance value is large. At this time, the impedance detection element can block the current of the radio frequency electrode and the electrical stimulation electrode, that is, shut down the treatment, to avoid the situation where energy is concentrated on the skin due to poor fitting, causing burns, or insufficient energy, resulting in poor treatment effect. The fitting detection component can also be a pressure detection element. After the flexible electrode sheet 1 is fitted to the skin, the pressure value is fed back by the pressure detection element to determine whether the fit is good.

[0091] Please continue to refer to Figures 5 to 8. In one embodiment of the present application, a gripping portion 11 is provided at one end of the flexible electrode sheet 1, and a connection position 12 is provided at the end of the gripping portion 11 away from the flexible electrode sheet 1. The radio frequency electrode and the electrical stimulation electrode are electrically connected to the external control terminal through the connection position 12.

[0092] In this embodiment, the gripping portion 11 provided at one end of the flexible electrode sheet 1 is used to hold the flexible electrode sheet 1 when it is fitted to the face, thereby improving the operational convenience for medical staff. The gripping portion 11 can be formed by a protrusion at the end of the flexible electrode sheet 1. A connection position 12 is provided at one end of the gripping portion 11 away from the flexible electrode sheet 1. The connection position 12 is electrically connected to the radio frequency electrode and the electrical stimulation electrode. The connection position 12 can be used to connect to an external power source or a host to power the radio frequency electrode and the electrical stimulation electrode. At the same time, the polarity, frequency, power, current and other parameters of the electrode can be adjusted by the host, further improving the convenience and therapeutic effect of the flexible electrode sheet 1 on skin treatment.

[0093] The flexible electrode sheet 1 also includes a position detection element (not shown). The flexible electrode sheet 1 includes various shapes and can be two flexible electrode sheets 1 with left and right mirror symmetry, which is convenient for treating the left and right sides of the face at the same time. The position detection element is electrically connected to the external host. When the flexible electrode sheet 1 is connected to the interface of the host, the host can automatically determine the type of flexible electrode sheet 1 by detecting the properties of the position detection element and supply power according to the set electrode properties. There is no need to determine multiple types of interface designs to match different flexible electrode sheets 1, thereby further improving the convenience of operation.

[0094] The present application also proposes a therapeutic device (not shown), which includes a therapeutic device and a flexible electrode sheet 1. The specific structure of the flexible electrode sheet 1 refers to the above embodiment. Since the present therapeutic device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0095] The therapeutic device comprises at least a main unit. This unit is electrically connected to the flexible electrode sheet 1, providing power for the electrodes. The main unit is also in communication with the flexible electrode sheet 1, enabling control of the electrode polarity, adjustment of parameters such as the electrode's radiofrequency frequency, radiofrequency power, and electrical stimulation current, and display of the flexible electrode sheet 1's operating status and parameters, thereby enhancing operational convenience for medical personnel.

[0096] The present application proposes a flexible electrode sheet 1 .

[0097] As shown in Figures 9 and 10, in one embodiment of the present application, a flexible electrode sheet 1 is used to attach to and treat cheek skin. The flexible electrode sheet 1 includes a base 10, a plurality of radio frequency electrodes and a plurality of electrical stimulation electrodes. The shape of the base 10 is at least partially arc-shaped, and one end of the base 10 is recessed toward the other end to form a groove 13a; the plurality of radio frequency electrodes are spaced apart on the surface of the base 10 and electrically connected to an external power supply for generating radio frequency energy; the plurality of electrical stimulation electrodes are spaced apart on the surface of the base 10 and electrically connected to an external power supply for generating microcurrent.

[0098] In this embodiment, the base 10 is at least partially elliptical, matching the shape of the cheek to improve the fit of the flexible electrode sheet 1 to the cheek skin. Furthermore, a groove 13a is formed at one end of the base 10, recessed toward the other end. When the flexible electrode sheet 1 is in contact with the cheek, the groove 13a aligns with the position of the mouth, preventing the mouth from affecting the fit of the flexible electrode sheet 1 to the cheek, thereby improving the fit of the flexible electrode sheet 1 to the cheek skin. Radiofrequency electrodes and electrostimulation electrodes are provided on the surface of the base 10 and are both electrically connected to an external power source. The radiofrequency electrodes generate radiofrequency energy to induce frictional movement of molecules within the skin, accumulating heat within the dermis, promoting the contraction of existing collagen and the production of new collagen, thereby achieving cosmetic effects such as skin tightening, wrinkle reduction, and lifting. The electrostimulation electrodes generate microcurrents. Through current stimulation, these signals are directly transmitted to the muscles, prompting them to perform passive high-frequency movements, thereby depleting excess fat, sugar, and carbohydrates in the surrounding tissue. Furthermore, they stimulate the dermis, promoting collagen synthesis by cells, tightening contours, and refining the skin. The present application solves the problem of poor fitting between the existing flexible electrode sheet and the face, thereby improving the effect of cosmetic treatment.

[0099] As shown in FIG9 , in one embodiment of the present application, the RF electrode includes a first RF electrode 21 and a second RF electrode 22 that are spaced apart. One end of the first RF electrode 21 and the second RF electrode 22 are both close to the groove 13 a , and the other end thereof extends along the sidewall of the substrate 10 .

[0100] And / or, the base 10 is elliptical in shape.

[0101] In this embodiment, the first RF electrode 21 and the second RF electrode 22 are spaced apart. The distance between the RF electrodes affects the RF energy density and the treatment depth of the RF energy. The distance between the first RF electrode 21 and the second RF electrode 22 can be adjusted according to the actual treatment depth and energy level required, and no further limitation is given here. The first RF electrode 21 and the second RF electrode 22 are respectively located on both sides of the substrate 10, with one end close to the groove 13a of the substrate 10 and the other end extending along the side wall of the substrate 10 to increase the energy coverage of the RF electrodes, thereby improving the RF treatment effect. At the same time, when the flexible electrode sheet 1 is attached to the cheek, the groove 13a is attached near the mouth. Therefore, one end of the first RF electrode 21 and the second RF electrode 22 is placed close to the groove 13a to improve the treatment effect of the RF energy on the skin near the masseter muscle.

[0102] When the RF electrode is limited to include the first RF electrode 21 and the second RF electrode 22 or not, the shape of the base 10 can be elliptical to match the cheek skin contour of the human face, further improving the fit between the flexible electrode sheet 1 of the facial mask and the facial skin.

[0103] Please continue to refer to Figure 9. In one embodiment of the present application, the electrical stimulation electrode includes a first electrical stimulation electrode 31 and a second electrical stimulation electrode 32 that are arranged opposite to each other. The first electrical stimulation electrode 31 and the second electrical stimulation electrode 32 are both arranged in the middle of the substrate 10.

[0104] In this embodiment, the first and second electrical stimulation electrodes 31, 32 may be rectangular in shape and positioned in the middle of the base 10 to electrically stimulate the skin in the middle of the cheek, thereby improving skin firmness in areas such as the apple of the cheek and the masseter muscles. Of course, different electrical stimulation shapes and positions may also be configured based on actual needs. The first and second electrical stimulation electrodes 31, 32 may be positioned in one location or multiple locations to achieve electrical stimulation of the skin over different areas.

[0105] In one embodiment of the present application, the plurality of electrical stimulation electrodes are arranged along the outer wall of the substrate 10 and extend from one end to the other end of the substrate 10;

[0106] And / or, the plurality of RF electrodes are spaced apart and disposed in the middle of the substrate 10 .

[0107] In this embodiment, multiple electrical stimulation electrodes are spaced apart and positioned close to the outer wall of the substrate 10, extending from one end of the substrate 10 to the other. For example, the electrical stimulation electrodes can be positioned on both sides of the substrate 10, with their shapes matching the sidewalls of the substrate 10. The microcurrent is transmitted from one side of the flexible electrode sheet 1 to the other, thereby increasing the coverage of the microcurrent and expanding the electrical stimulation treatment area.

[0108] In the case where the electrical stimulation is limited or not limited to the outer wall of the substrate 10, multiple RF electrodes are spaced apart in the middle of the substrate 10. Placing multiple RF electrodes in the middle of the substrate 10 can reduce the spacing between the RF electrodes to improve the uniformity of the RF energy density.

[0109] As shown in FIG9 and FIG10 , in one embodiment of the present application, a plurality of cutouts 14 a are formed on the periphery of the base 10 ;

[0110] And / or, a through groove 15 a is formed on the base 10 , and the through groove 15 a extends from one end to the other end of the base 10 .

[0111] In this embodiment, the shape of the incision 14a can be triangular, rectangular, or the like. Multiple incisions 14a are provided, spaced apart around the periphery of the base 10 to enhance the flexibility of the flexible electrode sheet 1 and facilitate adherence to facial skin. The depth, size, and position of the incision 14a can be designed based on the location of the RF electrodes and electrical stimulation electrodes of the flexible electrode sheet. The incision 14a should avoid these electrodes.

[0112] In cases where the incision 14a is defined or not defined on the periphery of the substrate 10, the flexible electrode sheet 1 also defines a through-groove 15a, with both ends of the through-groove 15a extending through the substrate 10. In this embodiment, the through-groove 15a is defined in the middle of the substrate 10 and extends from one end of the substrate 10 to the other. The through-groove 15a may be defined in one or multiple locations. The provision of through-groove 15a between the RF electrodes further enhances the flexibility of the flexible electrode sheet 1, allowing the RF electrodes and electrical stimulation electrodes to better adhere to the facial skin and improve the therapeutic effect.

[0113] 9 and 10 , in one embodiment of the present application, a gripping portion 11 is provided at one end of the flexible electrode sheet 1 away from the groove 13 a , and a connection position 13 is provided at one end of the gripping portion 11 away from the flexible electrode sheet 1 , through which the radio frequency electrode and the electrical stimulation electrode are electrically connected to the external control terminal;

[0114] And / or, the flexible electrode sheet 1 further includes a fit detection element (not shown), which is provided on the surface of the radio frequency electrode or the electrical stimulation electrode to determine the fit between the flexible electrode sheet 1 and the skin.

[0115] In this embodiment, a grip portion 11, located at the end of the flexible electrode sheet 1 away from the groove 13a, is used to hold the flexible electrode sheet when placed against a person's face, improving operational convenience for medical personnel. The grip portion 11 can be formed by a protrusion on the end of the flexible electrode sheet 1. A connection point 13 is provided at the end of the grip portion 11 away from the flexible electrode sheet. This connection point 13 is electrically connected to an external control terminal to provide power to the RF electrodes and electrical stimulation electrodes.

[0116] In the case where the flexible electrode sheet is limited or not to be provided with a grip portion, after the flexible electrode sheet 1 is in contact with the cheek skin, the fit detection element is used to detect whether the fit is good. The fit detection element can be an impedance detection element. After the flexible electrode sheet 1 is in contact with the skin, the impedance value at both ends of the flexible electrode sheet 1 is detected by the impedance detection element to determine whether the fit is good. When the fit is poor, the impedance value is large. At this time, the impedance detection element can block the current of the radio frequency electrode and the electrical stimulation electrode, that is, turn off the treatment, and avoid the situation where energy is concentrated on the skin due to poor fit, causing burns or insufficient energy leading to poor treatment effect. The fit detection component can also be a pressure detection element. After the flexible electrode sheet 1 is in contact with the skin, the pressure value is fed back by the pressure detection element to determine whether the fit is good.

[0117] The present application also proposes a flexible electrode sheet assembly.

[0118] As shown in FIG. 11 , in one embodiment of the present application, the flexible electrode sheet assembly includes two flexible electrode sheets 1 described above.

[0119] In this embodiment, the specific structure of the flexible electrode sheet 1 refers to the above-mentioned embodiments. Since the flexible electrode sheet assembly adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be described one by one here. Among them, the flexible electrode sheet assembly includes a flexible electrode sheet 1, wherein two flexible electrode sheets 1 are provided, and the two flexible electrode sheets 1 have the same mirror-symmetrical structure and fit the left face and the right face respectively. The two flexible electrode sheets 1 can generate radio frequency energy and microcurrent individually, or interact with each other to generate radio frequency energy and microcurrent. By providing two mirror-symmetrical flexible electrode sheets 1, the bulge of the nose and the position of the mouth can be avoided, thereby improving the fit between the flexible electrode sheet assembly and the face.

[0120] Please continue to refer to FIG11 . In one embodiment of the present application, the multiple radio frequency electrodes of one flexible electrode sheet 1 are all positive electrodes, and the multiple radio frequency electrodes of another flexible electrode sheet 1 are all negative electrodes.

[0121] And / or, the multiple electrical stimulation electrodes of one flexible electrode sheet 1 are all positive electrodes, and the multiple electrical stimulation electrodes of another flexible electrode sheet 1 are all negative electrodes;

[0122] In this embodiment, the first RF electrode 21 and the second RF electrode 22 in the same flexible electrode sheet 1 have the same polarity: the RF electrodes of one flexible electrode sheet 1 are both positive, while the RF electrodes of the other flexible electrode sheet 1 are both negative. The RF electromagnetic field propagates through one flexible electrode sheet 1 to the other, achieving the effect of simultaneously treating the skin on both the left and right sides of the face.

[0123] With or without limiting the polarity of the radiofrequency electrodes of the two flexible electrode sheets 1, the polarity of the first and second electrical stimulation electrodes 31, 32 in the same flexible electrode sheet 1 is the same, with the electrical stimulation electrodes of one flexible electrode sheet 1 both being positive and the electrical stimulation electrodes of the other flexible electrode sheet 1 both being negative. The microcurrent is transmitted through one flexible electrode sheet 1 to the other flexible electrode sheet 1, thereby achieving the effect of simultaneously treating the left and right sides of the face.

[0124] In other embodiments, the polarities of the first RF electrode 21 and the second RF electrode 22 in each flexible electrode sheet 1 are different, the polarities of the first electrical stimulation electrode 31 and the second electrical stimulation electrode 32 in each flexible electrode sheet 1 are different, and the RF energy and microcurrent are transmitted between the RF electrode and the electrical stimulation electrode provided on each flexible electrode sheet 1.

[0125] As shown in Figure 12, in one embodiment of the present application, the flexible electrode sheet assembly also includes a flexible eye electrode sheet, which is arc-shaped and is provided with a third radio frequency electrode 41 and a third electrical stimulation electrode 42 to generate radio frequency energy and microcurrent to treat the eye skin.

[0126] In this embodiment, the flexible electrode sheet assembly also includes an arc-shaped flexible eye electrode sheet for attachment to the canthus and lower orbital region to treat the skin around the eye. The eye flexible electrode sheet is provided with a third radiofrequency electrode 41 and a third electrical stimulation electrode 42, and is electrically connected to an external power source to generate radiofrequency energy and microcurrent. The first radiofrequency electrode 21 and the second radiofrequency electrode 22 may be provided in a single location or multiple locations. When provided in multiple locations, they may be spaced apart along the direction in which the eye flexible electrode sheet extends.

[0127] 12 , in one embodiment of the present application, the third RF electrode 41 has a different polarity from at least one RF electrode of the flexible electrode sheet 1 , and the third electrical stimulation electrode 42 has a different polarity from at least one electrical stimulation electrode of the flexible electrode sheet 1 .

[0128] In one embodiment, the polarity of the multiple third RF electrodes 41 can be the same or different, and the polarity of the multiple third electrical stimulation electrodes 42 can be the same or different. In this embodiment, the polarity of the third RF electrodes 41 and the third electrical stimulation electrodes 42 can both be positive, and at least one of the RF and electrical stimulation electrodes of the flexible electrode sheet 1 can be negative. This allows the RF energy and microcurrent to be transmitted along the direction from the eye to the cheek. This reduces the risk of RF energy and microcurrent passing through the eyeball, minimizing their impact on the eyeball and improving treatment safety.

[0129] The present application also proposes a therapeutic device (not shown), which includes any of the above-mentioned flexible electrode sheets 1 or flexible electrode sheet components, as well as a complete therapeutic device and a flexible electrode sheet. The specific structures of the flexible electrode sheet 1 and the flexible electrode sheet component refer to the above-mentioned embodiments. Since the present therapeutic device adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0130] The therapeutic device comprises at least a main unit. The main unit is electrically connected to the flexible electrode sheet 1 or flexible electrode sheet assembly, providing power for the electrodes. The main unit is also communicatively connected to the flexible electrode sheet 1 or flexible electrode sheet assembly, enabling control of the electrode polarity, adjustment of parameters such as the electrode's radio frequency frequency, radio frequency power, and electrical stimulation current, and display of the operating status and parameters of the flexible electrode sheet 1 or flexible electrode sheet assembly, thereby enhancing operational convenience for medical personnel.

[0131] The present application proposes a flexible electrode sheet 1 .

[0132] As shown in Figures 13 to 20, in one embodiment of the present application, the flexible electrode sheet 1 includes a base 10, a plurality of radio frequency electrodes and a plurality of electrical stimulation electrodes; the base 10 includes a first end 14 and a second end 15 connected to each other, and the first end 14 and the second end 15 are bent at the connection; the plurality of radio frequency electrodes are respectively arranged at the first end 14 and the second end 15, and the polarity of at least one radio frequency electrode is different from the polarity of the other radio frequency electrodes, and the radio frequency electrode is electrically connected to an external power supply to generate radio frequency energy; the plurality of electrical stimulation electrodes are respectively arranged at the first end 14 and the second end 15, and the polarity of at least one electrical stimulation electrode is different from the polarity of the other electrical stimulation electrodes, and the electrical stimulation electrode is electrically connected to an external power supply to generate microcurrent.

[0133] In this embodiment, the substrate 10 may be a flexible circuit board, and the material may be PI (polyimide), PET (polyester), PEN (polyethylene terephthalate), etc., which has a certain flexibility to improve the closeness of the flexible electrode sheet 1 to the skin. The substrate 10 includes a first end 14 and a second end 15 connected to each other. The first end 14 is bent relative to the second end 15 at the connection point to match the contour of the eye, so as to improve the fit between the flexible electrode sheet 1 and the eye. The radio frequency electrode is used to generate radio frequency energy. Radio frequency electrodes of different polarities can be respectively arranged at both ends of the substrate 10, or radio frequency electrodes of different polarities can be spaced apart in a direction perpendicular to the first end 14 or the second end 15. Radio frequency energy is transmitted between radio frequency electrodes of different polarities to achieve a therapeutic effect. At the same time, an electrical stimulation electrode is also provided on the substrate 10 to generate microcurrent, thereby achieving a therapeutic effect on the skin.

[0134] This application achieves a cosmetic treatment effect by providing radiofrequency electrodes and electrical stimulation electrodes on a flexible electrode sheet 1 and attaching the radiofrequency electrodes and electrical stimulation electrodes to the skin. Furthermore, the flexible electrode sheet 1 is designed to be curved to match the contours of the eye, thus resolving the problem of poor adhesion between the flexible electrode sheet 1 and the eye and improving the effectiveness of the cosmetic treatment.

[0135] As shown in FIG. 13 to FIG. 16 , in one embodiment of the present application, the angle between the first end 14 and the second end 15 is 30° to 120°;

[0136] And / or, a chamfer is provided at the connection between the first end 14 and the second end 15 .

[0137] In this embodiment, the first end 14 and the second end 15 are symmetrical along the connection. The first end 14 and the second end 15 are rectangular in shape, but may also be cylindrical. The first end 14 is bent relative to the second end 15 at the connection, forming an angle of 30° to 120° to better match the canthus of the eye, further improving the fit of the flexible electrode sheet 1 to the eye.

[0138] In the case where the angle between the first end 14 and the second end 15 is limited or not, a rounded chamfer is provided at the connection between the first end 14 and the second end 15 to avoid local concentration of radio frequency energy at the sharp edges of the flexible electrode sheet 1, resulting in uneven energy. At the same time, the sharp edges are prevented from scratching the facial skin.

[0139] As shown in Figures 17 and 18, in one embodiment of the present application, a bending portion 141 is formed at the end of the first end 14 away from the connection, and the bending portion 141 is bent along the bending direction of the first end 14, and an extension portion 151 is formed at the end of the second end 15 away from the connection, and the extension portion 151 is extended along the bending direction of the second end 15.

[0140] In this embodiment, the first end 14 extends from the end away from the connection to form an extension portion 141. The extension portion 141 increases the coverage area of ​​the flexible electrode sheet 1 on the eye, especially allowing treatment of the lower eye socket, thereby improving the therapeutic effect of the flexible electrode sheet 1. The second end 15 is bent at the end away from the connection to form a bent portion 151. The bent portion 151 further facilitates the flexible electrode sheet 1 to fit the area on both sides of the eyebrow, thereby increasing the coverage area of ​​the flexible electrode sheet 1 on the eye and further improving the therapeutic effect on the skin around the eye.

[0141] As shown in Figures 13 to 20, in one embodiment of the present application, the RF electrode includes a first RF electrode 21 and a second RF electrode 22 with different polarities. The first RF electrode 21 and the second RF electrode 22 are arranged at intervals. The first RF electrode 21 is arranged at the first end 14, and the second RF electrode 22 is arranged at the second end 15.

[0142] In this embodiment, the first RF electrode 21 and the second RF electrode 22 have different polarities. When the RF electrodes are energized, a radio frequency electromagnetic field is generated between the first RF electrode 21 and the second RF electrode 22, causing frictional movement of molecules within the tissue and accumulating heat within the dermis, thereby promoting the contraction of existing collagen and the production of new collagen, thereby achieving the cosmetic effects of skin tightening, wrinkle removal, and lifting. The first RF electrode 21 and the second RF electrode 22 are spaced apart to increase the coverage of the RF energy, thereby improving the treatment range. The distance between the RF electrodes affects the RF energy density and the treatment depth of the RF energy. The distance between the first RF electrode 21 and the second RF electrode 22 can be adjusted according to the actual treatment depth and energy level required, and no further limitation is given here.

[0143] The shapes of the first end 14 and the second end 15 can be cylindrical, rectangular, arc-shaped, etc. The first RF electrode 21 is arranged at the first end 14, and the second RF electrode 22 is arranged at the second end 15. The RF energy is transmitted along the first end 14 to the second end 15 of the flexible electrode sheet 1. The RF energy has a large range of action and a wide treatment range. The shapes of the first RF electrode 21 and the second RF electrode 22 can both be trapezoidal, and the two sides of the trapezoid are convex arcs, and are respectively close to the ends and connections of the flexible electrode sheet 1, so as to match the shapes of the first end 14 and the second end 15 and the connections, thereby reducing the distance between the RF electrode and the outer edge of the flexible electrode sheet 1 to increase the coverage of the RF energy. In other embodiments, the shapes of the first RF electrode 21 and the second RF electrode 22 can also be rectangular.

[0144] As shown in Figures 15 and 19, in one embodiment of the present application, the RF electrode includes a first RF electrode 21 and a second RF electrode 22 with different polarities. The first RF electrode 21 extends from the first end 14 to the second end 15, and the second RF electrode 22 extends from the first end 14 to the second end 15 and is spaced apart from the first RF electrode 21.

[0145] In this embodiment, the first RF electrode 21 and the second RF electrode 22 are both curved and extend from the first end 14 to the second end 15 of the flexible electrode sheet 1. The RF energy is transmitted in a direction perpendicular to the bending direction of the flexible electrode sheet 1, thereby reducing the risk of RF energy passing through the eyeball and improving the safety of RF treatment.

[0146] 15 and 19 , in one embodiment of the present application, both ends of the first RF electrode 21 are bent toward the second RF electrode 22 to form a bent portion 2111 , and both ends of the second RF electrode 22 are provided with a protruding portion 2211 , which is disposed close to the bent portion 2111 .

[0147] In this embodiment, both ends of the first RF electrode 21 are bent toward the second RF electrode 22 to form a curved portion 2111. The curved portion 2111 can be arc-shaped to match the shapes of the first end 14 and the second end 15, thereby improving the coverage of the RF electrode and reducing the uneven energy density caused by the concentration of RF energy at sharp corners. The second RF electrode 22 is provided with a raised portion 2211 at both ends that matches the curved portion 2111. The raised portion 2211 can be circular and positioned near the curved portion 2111. By providing the curved portion 2111 and the raised portion 2211 at both ends of the RF electrode, the uniformity of the energy density at the ends of the RF electrode is improved, thereby further enhancing the therapeutic effect.

[0148] As shown in Figures 13 and 17, in one embodiment of the present application, the electrical stimulation electrode includes a first electrical stimulation electrode 31 and a second electrical stimulation electrode 32 with different polarities. The first electrical stimulation electrode 31 is arranged at the first end 14, and the second electrical stimulation electrode 32 is arranged at the second end 15.

[0149] In this embodiment, the first and second electrostimulation electrodes 31, 32 function by stimulating the skin's muscle layer with a microcurrent emitted by an electrostimulation (EMS) electrode, thereby achieving a therapeutic effect. EMS technology uses electrical stimulation to directly transmit signals to the muscles, prompting them to perform passive high-frequency movements, thereby depleting excess fat, sugar, and carbohydrates in the surrounding tissue. It also stimulates the dermis, promoting collagen synthesis in cells, tightening contours, and refining the skin. The first and second electrostimulation electrodes 31, 32 have different polarities to facilitate microcurrent signal propagation between them. The first electrostimulation electrode 31 is located at the first end 14, and the second electrostimulation electrode 32 is located at the second end 15. This facilitates microcurrent transmission from one end of the flexible electrode sheet 1 to the other, thereby achieving a therapeutic effect across the widest area of ​​the canthus. The first and second electrostimulation electrodes 31, 32 can be trapezoidal or rectangular in shape. The shape and specific position of the electrostimulation electrodes can be designed to correspond to the shape and position of the muscle or tissue being treated, thereby enhancing the targeted therapeutic effect. In other embodiments, four electrical stimulation electrodes can be provided. Electrical stimulation electrodes of different polarities can be provided at one end of the flexible electrode sheet 1 or at both ends of the flexible electrode sheet 1. As long as the treatment of the skin can be satisfied, it falls within the scope of protection of this application.

[0150] As shown in FIG15 to FIG16 and FIG19 to FIG20, in one embodiment of the present application, a cutout 14a is provided on the outer periphery of the flexible electrode sheet 1;

[0151] And / or, the substrate 10 defines a through-groove 15 a , and the through-groove 15 a is located between the two RF electrodes.

[0152] In this embodiment, the shape of the incision 14a can be triangular, rectangular, etc. The incision 14a is provided on the outer periphery of the flexible electrode sheet 1, and can be provided at the connection between the first end 14 and the second end 15, to improve the flexibility of the flexible electrode sheet 1 and facilitate its fit to the skin around the eye. The incision 14a can be provided in one location or multiple locations. The depth, size, and position of the incision 14a can be designed according to the position of the radiofrequency electrodes and the electrical stimulation electrodes of the flexible electrode sheet 1. The incision 14a needs to avoid the positions of the radiofrequency electrodes and the electrical stimulation electrodes.

[0153] In cases where the incision 14a is defined or not defined on the periphery of the flexible electrode sheet 1, the base 10 further defines a through-groove 15a. The through-groove 15a extends from both ends and is located between the two RF electrodes. In this embodiment, the through-groove 15a is defined between the first RF electrode 21 and the second RF electrode 22 and extends along the direction in which the first RF electrode 21 and the second RF electrode 22 extend. The through-groove 15a may be defined in one or more locations. The provision of through-grooves 15a between the RF electrodes further enhances the flexibility of the flexible electrode sheet 1, allowing the RF electrodes and the electrical stimulation electrodes to better adhere to the skin around the eye, improving the therapeutic effect.

[0154] In one embodiment of the present application, the flexible electrode sheet 1 further includes a fit detection element (not shown), which is disposed on the surface of the radio frequency electrode or the electrical stimulation electrode to determine the fit between the flexible electrode sheet 1 and the skin.

[0155] In this embodiment, after the flexible electrode sheet 1 is fitted to the skin of the eye, a fitting detection element is used to detect whether the fit is good. The fitting detection element can be an impedance detection element. After the flexible electrode sheet 1 is fitted to the skin, the impedance detection element detects the impedance value at both ends of the flexible electrode sheet 1 to determine whether the fit is good. When the fit is poor, the impedance value is large. At this time, the impedance detection element can block the current of the radio frequency electrode and the electrical stimulation electrode, that is, shut down the treatment, to avoid the situation where energy is concentrated on the skin due to poor fitting, causing burns or insufficient energy resulting in poor treatment effect. The fitting detection component can also be a pressure detection element. After the flexible electrode sheet 1 is fitted to the skin, the pressure detection element feeds back the pressure value to determine whether the fit is good.
