Description

High-frequency output device

[0001] The present invention relates to a high-frequency output device.

[0002] Skin care devices are currently being developed to keep the skin clean through wrinkle removal, restoration of skin elasticity, and sebum removal. This is because clean skin makes a person look younger and contributes to an attractive appearance.

[0003] Skin care devices include types that transmit ultrasound to the skin (HIFU type), types that transmit high frequency (RF type), and types that transmit laser light to the skin (Optical type).

[0004] Here, a high-frequency output device that delivers high-frequency waves to the skin applies high-frequency waves generated from RF electrodes to a target area of ​​the skin through the epidermis. As a result, as high-frequency waves are delivered to the target area of ​​the skin, coagulative necrosis is induced in the target area of ​​the skin, thereby removing collagen and elastic fibers in the target area of ​​the skin and allowing new collagen and elastic fibers to be formed. In addition, coagulative necrosis in the target area of ​​the skin is also effective in improving skin pigmentation, acne scars, and wrinkles.

[0005] High-frequency output devices can be classified into a bipolar type having a first polarity RF electrode and a second polarity RF electrode, and a monopolar type having an RF electrode of the same polarity and a ground electrode.

[0006] In the bipolar type, a first polarity RF electrode and a second polarity RF electrode are positioned with the target area of ​​the skin in between, and the current applied to the first polarity RF electrode is returned to the second polarity RF electrode, so that high frequency is oscillated into a relatively narrow area between the first polarity RF electrode and the second polarity RF electrode, so that high frequency can be intensively applied to the target area of ​​the skin.

[0007] In the monopolar type, the current applied to the RF electrode of the same polarity placed on the target area of ​​the skin is returned to the counter electrode placed on the non-target area of ​​the skin (e.g., abdomen, back of the body), and since high frequency is generated in a relatively wide area between the RF electrode of the same polarity and the counter electrode, high frequency can be applied not only to the target area of ​​the skin but also to the surrounding area of ​​the target area of ​​the skin.

[0008] Meanwhile, when high-frequency waves are output to the skin from a planar RF electrode (hereinafter referred to as the 'planar electrode'), an edge effect occurs in which the high-frequency density output from the edge of the planar electrode is relatively higher than the high-frequency density output from the center of the planar electrode. Consequently, there was a problem in that the temperature of the skin area receiving high-frequency waves output from the edge of the planar electrode was relatively higher than the skin area receiving high-frequency waves output from the center of the planar electrode.

[0009] To improve this, conventionally, the high-frequency output at the edges of the planar electrode was limited by covering the edges with a film. Consequently, the conventional technology had a problem in that the size of the high-frequency output area (=skin treatment area) of the planar electrode was reduced and the skin treatment effect was also lowered as the high-frequency output at the edges of the planar electrode was limited.

[0010] The present invention has been devised to solve the aforementioned problems, and the objective of the present invention is to provide a high-frequency output device capable of preventing the occurrence of edge effects during high-frequency output and mitigating uneven temperature distribution and temperature deviations in the skin area receiving the high-frequency.

[0011] The problems that the present invention aims to solve are not limited to those mentioned above, and other unmentioned problems will be clearly understood by a person skilled in the art from the description below.

Furthermore, terms defined in commonly used dictionaries are not to be interpreted ideally or excessively unless explicitly and specifically defined otherwise.

[0052] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0053] FIGS. 1 to 16 are schematic diagrams showing various embodiments of a high-frequency output device according to one embodiment of the present invention, and FIG. 17 is a block diagram showing a high-frequency output device according to one embodiment of the present invention.

[0054] As illustrated in FIGS. 1 to 17, a high-frequency output device according to one embodiment of the present invention may include a base (10), an electrode (20), a high-frequency generator (30), and a processor (40). In one embodiment, the base (10) and the electrode (20) form a tip that is detachable and connectable from a handpiece, and the high-frequency generator (30) and the processor (40) may be included in the handpiece or the main body of the high-frequency output device.

[0055] An electrode (20) may be formed on the base (10). In one embodiment, the base (10) may have a plate shape. For example, the base (10) may include a plate-shaped surface that contacts the skin surface for high-frequency output.

[0056] The base (10) can be detachably coupled to one side of the handpiece of the high-frequency output device to be described later.

[0057] The electrode (20) is formed on the base (10) and can output high frequency to the skin when power is applied. The electrode (20) may be provided in a part of the base (10). That is, the electrode (20) is provided on the base (10) so that an electrode area including the outermost part of the electrode (20) can be formed.

[0058] Additionally, the electrode region may include a central region, a border region, and a region between the central region and the border region. In one embodiment, the central region may be defined as the central point itself within the electrode (20) or as a region extending toward the border region by a predetermined size while including the central point, the border region may be defined as the border itself within the electrode (20) or as a region extending from the border toward the central region by a predetermined size, and the region between may be defined as the space between the central region and the border region described above.

[0059] The electrode (20) may have a non-uniform electrode density. Here, the electrode density can be defined as the ratio of the area where the electrode (20) is formed per unit area of ​​the base (10). Here, the unit area (11) of the base (10) can be defined as each area among a plurality of reference areas divided into a certain size on the plane of the base (10). The size or shape of such unit area (11) is not particularly limited, and for reference, an example in which a plurality of unit areas (11) are in a grid shape is illustrated in FIG. 1.

[0060] In one embodiment, the electrode (20) may have a maximum electrode density in the central region, a minimum electrode density in the edge region, and an electrode density in the region between the central region and the edge region that is less than or equal to the maximum value and greater than or equal to the minimum value. When the electrode (20) has a specific area and has the same electrode density, when current is applied, the current is concentrated in the outermost region of the electrode (20), so that energy is not applied to the entire skin surface where the electrode (20) is in contact, and an edge phenomenon occurs in which energy is concentrated at the outermost region. To solve this, the edge region where the edge phenomenon occurs is formed with a minimum electrode density, and the central region is formed with a maximum electrode density so that energy can be applied to the entire electrode region. The region between may have an electrode density that is less than or equal to the maximum value and greater than or equal to the minimum value.

[0061] Additionally, in one embodiment, the electrode density may decrease as it moves away from the center of the base (10). That is, the central region of the electrode area corresponds to the central point, and as it moves away from the central point, the electrode density decreases, and the electrode density may be minimized in the edge region. The electrode density may decrease continuously or discontinuously as it moves away from the center.

[0062] In addition, in another embodiment, the central region forms the same electrode density over the entire area, while the border region and the intermediate region decrease as they move away from the center of the base (10). That is, the central region corresponds to an area with a specific surface area, and the central region can have the maximum electrode density in the electrode region without a change in electrode density. For example, the central region can be formed without any part where the electrode (20) is not placed. And, the border region and the intermediate region are formed to decrease as they move away from the center of the base (10), thereby preventing the occurrence of an edge effect in the border region.

[0063] Accordingly, when power of the same polarity is applied to the electrode (20) from the high-frequency generator (30), compared to when an edge effect occurs in a conventional electrode, the monopolar type high-frequency density output from the edge region of the electrode (20) decreases relatively as it moves away from the center region of the electrode (20). As a result, as the difference between the monopolar type high-frequency density output from the center region of the electrode (20) and the monopolar type high-frequency density output from the edge region of the electrode (20) is mitigated, the edge effect, in which the monopolar type high-frequency density output from the edge region of the electrode (20) is relatively higher than the monopolar type high-frequency density output from the center region of the electrode (20), is reduced. In this way, as the occurrence of the edge effect is prevented, the uneven temperature distribution of the skin area receiving the monopolar type high-frequency output from the electrode (20) is mitigated, and thermal equilibrium can be achieved.

[0064] In addition, as an embodiment, in order to further improve the edge phenomenon described above, the outer edge of the electrode (20) may be covered with a dielectric or an insulator, and as an example, the outer edge of the electrode (20) may be covered with a Kapton film.

[0065] The high-frequency generator (30) can serve to supply power to the electrode (20). The high-frequency generator (30) can be connected to the electrode (20) through a first terminal (51) and a second terminal (52). The first terminal (51) can connect one side of the high-frequency generator (30) and the electrode (20). The second terminal (52) can connect the other side of the electrode (20).

[0066] The processor (40) can control the high-frequency generator (30) so that a high-frequency pattern including at least one of a monopolar type high frequency or a bipolar type high frequency is output from the electrode (20). Here, the high-frequency pattern can be transmitted to the skin.

[0067] Hereinafter, various embodiments of the electrode (20) will be described with reference to FIGS. 1 to 16.

[0068] As shown in FIGS. 1 to 8, the electrode density may decrease as it moves away from the central region of the electrode (20).

[0069] In one embodiment of the present invention, the electrode (20) may include a first pattern (21) formed in a central region and at least one second pattern (22) formed in an intermediate region and a border region. Here, the central region and the intermediate region and border region other than the central region have different electrode patterns. The electrode pattern may be an electrode having a pattern formed by a combination of one or more unit electrodes. As the first pattern (21) and the second pattern (22) have different electrode densities, the central region and the remaining region may have different electrode densities. That is, as the first pattern (21) in the central region has a higher electrode density than the second pattern (22) in the remaining region, the edge effect can be reduced.

[0070] Additionally, in one embodiment, the second pattern (22) may have a region where no electrode is placed between the second unit electrodes (22a). That is, the second pattern (22) may be in the form where one or more second unit electrodes (22a) are placed, with the electrode existing only in a partial range and the electrode not being placed in a portion, and the electrode density may change based on the ratio of the portion where no electrode is placed. At this time, the second pattern (22) may be continuously connected with the same shape of the second unit electrodes (22a) or with the size and shape being deformed.

[0071] Additionally, in one embodiment, the first pattern (21) may be formed as a single pattern. The first pattern (21) may be formed entirely on the surface of the central region. In this case, the first pattern (21) may be a pattern with a constant electrode density. For example, the first pattern (21) provided in a central region having a specific area may be formed in a plain shape in which there is no part where electrodes are not placed. Through this, as the first pattern (21) is formed in a plain shape, the central region may have a maximum electrode density as the area of ​​the region and the area where electrodes are formed coincide.

[0072] In addition, if the first pattern (21) is different from the second pattern (22), it can be a pattern in which the electrode density changes.

[0073] Additionally, at least one second pattern (22) can be electrically connected to the first pattern (21) and formed with a gap between the electrode (20) and the border area.

[0074] In one embodiment of the present invention, with reference to FIG. 1, a first pattern (21) may be formed over the entire central region of the electrode (20), and at least one second pattern (22) may be formed at intervals along a direction away from the central region of the electrode (20).

[0075] In the present embodiment, the first pattern (21) may have a circular shape. The first pattern (21) is not limited thereto and may be formed in various shapes including angles or curvatures.

[0076] Additionally, in one embodiment, the second pattern (22) may have a plurality of circular band-shaped electrode shapes of different sizes. In this case, the band-shaped electrodes of the second pattern (22) may have a larger diameter as they move further away from the central region. In this case, the second unit electrode (22a) forming the second pattern (22) may be each of the band-shaped electrodes forming the second pattern (22), or it may be an individual unit formed by an adjacent band-shaped electrode and a connecting electrode (23a). However, the present invention is not limited thereto, and the plurality of circular band-shaped electrodes may be connected in various ways. Furthermore, the second pattern (22) is not limited to a plurality of circular band shapes of different sizes, but may be formed as band electrodes of various shapes including angles or curvatures.

[0077] In one embodiment, a connecting electrode that connects across a plurality of circular band electrodes may be provided, and a plurality of connecting electrodes may be provided to form a connecting pattern (23).

[0078] Here, connecting electrodes can be gathered to form a connecting pattern (23), and can serve to connect the first pattern (21) and the second unit electrode (22a) of the second pattern (22). That is, the connecting pattern (23) may include at least one connecting electrode (23a).

[0079] That is, the second pattern (22) has a connecting pattern (23) that connects strip-shaped electrodes arranged in a direction of increasing size away from the center of the electrode area. The connecting pattern (23) included in the second pattern (22) is extended and electrically connected to the first pattern (21) arranged in the central area. In the connecting pattern (23), at least one connecting electrode (23a) extends in a direction away from the first pattern (21) and is formed at intervals along the circumferential direction of the inter-area and border areas of the electrode (20) and can be connected to at least one second unit electrode (22a) of the second pattern (22).

[0080] In addition, in one embodiment, the first terminal (51) and the second terminal (52) are connected to the connection pattern (23) and can be electrically connected to the first pattern (21) and the second pattern (22) through the connection pattern (23).

[0081] In one embodiment, compared to the connection pattern (23) of FIG. 1, the connection pattern (23) of FIG. 2 may be composed of a larger number of connections than the connection pattern (23) of FIG. 1. Through this, as the range of high frequency output from the electrode (20) is widened, the high frequency can be transmitted to a wider area of ​​the skin. Furthermore, the width of the connection pattern (23) may become narrower as it moves away from the central area of ​​the electrode (20). Through this, as the range of high frequency output from the electrode (20) is widened, the high frequency can be transmitted to a wider area of ​​the skin.

[0082] In one embodiment, the first pattern (21) of FIG. 3 may have a polygonal shape when compared to the first pattern (21) of FIG. 1. Also, the second pattern (22) of FIG. 3 may have a polygonal shape when compared to the second pattern (22) of FIG. 1. For example, the first pattern (21) and the second pattern (22) may have an octagonal shape, but the present invention is not limited thereto.

[0083] In one embodiment, compared to the connection pattern (23) of FIG. 3, the connection pattern (23) of FIG. 4 may be composed of a larger number of connections than the connection pattern (23) of FIG. 3. Through this, as the range of high frequency output from the electrode (20) is widened, the high frequency can be delivered to a wider area of ​​the skin.

[0084] In one embodiment, referring to FIGS. 1 to 4, the spacing between adjacent second unit electrodes (22a) included in the second pattern (22) can be formed to increase as it moves further away from the central region of the electrode (20). At this time, the area formed by the second pattern (22) in the inter-region and border regions of the electrode (20) per unit area of ​​the base (10) can be gradually reduced as it moves further away from the central region.

[0085] In one embodiment, referring to FIGS. 1 to 4, the width of an adjacent second unit electrode (22a) included in the second pattern (22) can be formed to become narrower as it moves away from the central region of the electrode (20). Accordingly, the area formed by the second pattern (22) per unit area of ​​the electrode (20) can gradually become smaller as it moves away from the central region of the electrode (20).

[0086] Additionally, in one embodiment, referring to FIG. 5, the first pattern (21) includes a first unit electrode (the same number as the first pattern) formed with a specific electrode density over the entire central region having a specific area range from the center of the electrode (20), and the second pattern (22) includes a plurality of second unit electrodes (22a), and the plurality of second unit electrodes (22a) may be formed with a gap between adjacent second unit electrodes (22a) by extending radially from the first pattern (21). The plurality of second unit electrodes (22a) may be arranged continuously in a radial direction from the center or arranged in a radial line, or they may be arranged continuously in a tilted or bent shape rather than in a radial direction.

[0087] For example, the first pattern (21) is formed over the entire central region of the electrode (20), and each second unit electrode (22a) included in the second pattern (22) extends from the first pattern (21) and can be formed with spacing along the circumferential direction of the inter-region and border regions of the electrode (20). Here, the spacing between adjacent second unit electrodes (22a) included in the second pattern (22) can be formed to increase as they move further away from the central region.

[0088] In one embodiment, referring to FIG. 6, the width of an adjacent second unit electrode (22a) included in the second pattern (22) can be formed to become narrower as it moves away from the central region of the electrode (20). Accordingly, the area formed by the second pattern (22) per unit area of ​​the inter-region and border region of the electrode (20) can become smaller as it moves away from the central region of the electrode (20).

[0089] Additionally, in another embodiment, a third pattern (24) may be further included in an area where the second unit electrode (22a) of the second pattern (22) of the intermediate area and the border area is not placed. In one embodiment, the third pattern (24) may include a plurality of third unit electrodes (24a) formed by extending from the first pattern (21) or the second pattern (22).

[0090] In one embodiment, referring to FIG. 7, the third unit electrode (24a) included in the third pattern (24) is formed by extending from the second unit electrode (22a) included in the second pattern (22) and is formed spaced apart from the adjacent third unit electrode (24a).

[0091] In one embodiment, as shown in FIG. 7, the first pattern (21) may be formed over the entire central region of the electrode (20), and the second pattern (22) may be formed by extending from the first pattern (21) and may include a plurality of second unit electrodes (22a) formed at intervals along the circumferential direction of the inter-region and border regions within the electrode region, and the electrode (20) may further include at least one third pattern (24). The third pattern (24) may include at least one third unit electrode (24a), and the third unit electrode (24a) may be formed at intervals along the inter-region and border regions of the electrode (20) and extend circumferentially from each second unit electrode (22a) of the second pattern (22). At this time, at least one third unit electrode (24a) formed on one of the two adjacent second unit electrodes (22a) may be formed offset from at least one third unit electrode (24a) formed on the other of the two adjacent second unit electrodes (22a).

[0092] In one embodiment, referring to FIG. 8, the third pattern (24) may be formed in a zigzag pattern on both sides of the second pattern (22). At this time, at least one third unit electrode (24a) formed on one of the two adjacent second unit electrodes (22a) may be formed offset from at least one third unit electrode (24a) formed on the other of the two adjacent second unit electrodes (22a).

[0093] In one embodiment, the first pattern (21) of FIG. 8 may have a smaller diameter than the first pattern (21) of FIG. 7 when compared to the first pattern (21) of FIG. 7. Also, the second unit electrode (22a) of the second pattern (22) of FIG. 8 may have a larger width than the second unit electrode (22a) of the second pattern (22) of FIG. 7 when compared to the second unit electrode (22a) of the second pattern (22) of FIG. 7.

[0094] FIGS. 18 to 24 are schematic diagrams showing other embodiments of a high-frequency output device according to one embodiment of the present invention.

[0095] In one embodiment of the present invention, the electrode (20) may include an electrode hole in which no electrode is placed in the electrode region. That is, by forming one or more electrode holes in which no electrode is placed in the electrode region, the electrode density of each part within the electrode region can be set differently.

[0096] In addition, in one embodiment of the present invention, the electrode (20) includes a first pattern (21) formed in a central region and at least one second pattern (22) formed in an intermediate region and a border region, and at least one of the first pattern (21) and the second pattern (22) may include an electrode hole of a specific shape in which no electrode is placed. That is, by forming one or more electrode holes in which no electrode is placed in the electrode region, the electrode density of each part within the electrode region can be set differently.

[0097] In one embodiment, the second pattern (22) includes a plurality of electrode holes, and the plurality of electrode holes may have the same area or shape. For example, the second pattern (22) may be formed by arranging a plurality of electrode holes that match in size and shape. Additionally, for example, the second pattern may be formed by arranging a plurality of electrode holes that have the same area but different shapes.

[0098] In addition, as an embodiment, the electrode holes may be formed in a circular shape or in a specific shape that is not circular. For example, as shown in FIG. 18, the electrode density may be controlled by arranging circular electrode holes (25a) to control the electrode density in each part, or as shown in FIG. 1 to 4, the electrode density may be controlled by forming holes of a specific shape that is not circular.

[0099] In addition, as in one embodiment, with reference to FIG. 18, the number of electrode holes (25a) can gradually increase as they move away from the central region. For example, if the number of electrode holes (25a) of the same size and shape in the second pattern (22) increases as they move away from the central region, the electrode density of the second pattern (22) decreases as it moves away from the center, as the area where electrodes are not placed increases as it moves away from the central region.

[0100] Additionally, in one embodiment, referring to FIG. 18, at least one electrode hole (25a) may be formed in the electrode (20). Here, the number of electrode holes (25a) formed per unit area of ​​the electrode (20) may gradually increase as it moves away from the central region of the electrode (20). At least one electrode hole (25a) may be formed at intervals along the edge of the electrode (20) to form at least one hole array (25). This at least one hole array (25) may have a greater number of electrode holes (25a) as it moves away from the central region of the electrode (20). The hole arrays (25) may be formed at intervals in a direction away from the central region of the electrode (20).

[0101] In addition, in another embodiment, referring to FIG. 22, the second pattern (22) includes at least one hole array (29) in which at least one electrode hole (29a) is formed spaced apart along the edge of the electrode, and the hole array (29) is formed such that the spacing between the electrode holes (29a) forming the hole array (29) becomes narrower as it moves away from the central region.

[0102] Additionally, referring to FIG. 22, the electrode (20) includes a first pattern (21) formed in a central region and at least one second pattern (22) formed in an intermediate region and a border region, and the first pattern (21) and the second pattern (22) may have regions where the electrode is not placed. The regions where the electrode is not placed may be electrode holes. Thus, both the first pattern (21) and the second pattern (22) may include electrode holes. Additionally, the number of electrode holes of the first pattern (21) may increase, the area may increase, and the spacing between the electrode holes may decrease as they move further away from the central region of the electrode.

[0103] Additionally, the second pattern (22) includes a plurality of electrode holes (29a), and the spacing between adjacent electrode holes (29a) may decrease as it moves further away from the central region, and the number of electrode holes (29a) may increase as it moves further away from the central region.

[0104] The hole arrays (29) may be formed at intervals in a direction away from the central region of the electrode (20). Additionally, the hole arrays (29) may be formed such that the spacing between the electrode holes (29a) forming the hole arrays (29) becomes narrower as they move away from the central region of the electrode (20). Here, the electrode (20) may have a circular shape. However, the electrode (20) is not limited thereto and may have various shapes including angles or curvatures.

[0105] As another example, referring to FIG. 23, the electrode (20) may have a polygonal shape.

[0106] The electrode includes a first pattern formed in the central region, an intermediate region, and at least one second pattern formed in the border region, and the second pattern may have a region where the electrode is not placed.

[0107] Here, at least one electrode hole (29a') may be formed at intervals along a polygonal border. Additionally, hole arrays (29') having at least one electrode hole (29a') may be formed at intervals in a direction away from the central region of the electrode (20). The second pattern (22) includes at least one hole array (29') in which at least one electrode hole (29a') is formed at intervals along the border of the electrode, and the hole array (29') is formed such that the spacing between the electrode holes (29a') forming the hole array (29') becomes narrower as it moves away from the central region.

[0108] Additionally, the outlines of the multiple hole arrays (29') may have different shapes. For example, the hole array (29') near the central region of the electrode in FIG. 23 may have a square shape, while the hole array (29') near the border region may have an octagonal shape. However, the shape is not limited to that of the present embodiment, and the shapes of the hole arrays (29') may vary within the electrode.

[0109] Here, the electrode of FIG. 23 may be the most preferred embodiment in which the electrode density has a maximum value in the central region of the electrode, a minimum value in the edge region, and an electrode density that is less than or equal to the maximum value and greater than or equal to the minimum value in the intermediate region. Additionally, as another embodiment, referring to FIG. 20, the second pattern (22) includes a plurality of electrode holes (25b), and the area or number of electrode holes (25b) may generally increase as they move away from the central region, but in some regions, they may not increase and may form electrode holes (25b) that are relatively smaller than adjacent electrode holes (25b). Also, the second pattern (22) may have the largest area or number of electrode holes (25b) in the outermost region of the electrode compared to other regions.

[0110] In addition, as another embodiment, referring to FIG. 21, the second pattern (22) includes at least one hole array (28) in which at least one electrode hole (28a) is formed at intervals along the circumferential direction of the electrode, wherein the electrode holes (28a) formed in the at least one hole array (28) may be formed at intervals in a direction offset from the circumferential direction of the electrode (20). The hole arrays (28) may be formed at intervals in a direction away from the central region of the electrode (20). That is, the arrangement of the electrode holes (28a) may be sporadically located without a fixed rule. Here, the second pattern (22) includes a plurality of electrode holes (28a), and the plurality of electrode holes (28a) may be formed irregularly with different sizes or shapes, and the electrode holes (28a) formed at the outermost edge of the electrode may have the largest size or the largest number, and may have the lowest electrode density at the outermost edge.

[0111] In addition, in one embodiment, the electrode hole is formed as one of a plurality of unit electrode hole types having different sizes or shapes, and is characterized by forming a change in electrode density through the arrangement of a plurality of electrode holes within the second pattern (22).

[0112] In one embodiment, referring to FIG. 20, at least one electrode hole (27a) may be formed in the electrode (20). Here, among the electrode holes (27a), those formed at the outermost edge of the electrode (20) may have the largest area. Additionally, electrode holes (27a) formed in the central region of the electrode (20) may have the smallest area, and electrode holes (27a) formed in the intermediate region of the electrode (20) may have an area that becomes larger as they move away from the central region of the electrode (20), then have a smaller area, and then have an area that becomes larger again. At least one electrode hole (27a) may be formed at intervals along the circumferential direction of the electrode (20) to form at least one hole array (27). The hole arrays (27) may be formed at intervals in a direction away from the central region of the electrode (20).

[0113] In addition, as another embodiment of the present invention, with reference to FIG. 19, the electrode (20) is connected in a spiral shape from the central region to the edge region. That is, as the electrode is arranged spirally within the electrode region, the ratio of the area where the electrode is formed per unit area of ​​the base (10) decreases as it moves away from the center, and thus the electrode density decreases.

[0114] Additionally, in one embodiment, the spacing between the spiral electrodes (20) increases as they move away from the central region. Through this, the electrode density can be reduced more significantly as it moves away from the central region.

[0115] In addition, in one embodiment, the width of the spiral electrode (20) decreases as it moves away from the central region. Through this, the electrode density can be reduced more significantly as it moves away from the central region.

[0116] In addition, as another embodiment, when the electrodes are arranged in a spiral shape, a unit electrode having a specific electrode density in a band shape may be formed in the edge region. At this time, a spiral hole (26) in the shape of a spiral may be formed between the electrodes (20).

[0117] In addition, as another embodiment of the present invention, with reference to FIG. 24, the electrode (20) includes a first pattern (21) formed in a central region and at least one second pattern (22) formed in an intermediate region and the border region, and the first pattern (21) may have an area where no electrode is placed. The area where no electrode is placed may be an electrode hole. Accordingly, the first pattern (21) may include an electrode hole. In addition, the number of electrode holes of the first pattern (21) may increase, the area may increase, and the spacing between electrode holes may decrease as they move away from the central region of the electrode.

[0118] Additionally, referring to FIG. 24, at least one sub-electrode (60) may be further included. In one embodiment, the sub-electrode (60) is connected to the electrode (20), and the sub-electrode (60) may have a higher electrode density compared to the connection portion (not shown) connected to the sub-electrode (60) in the first pattern (21) or the connection portion (22a-1) connected to the sub-electrode (60) in the second pattern (22). In a state where the electrode (20) has a maximum electrode density in the central region and a minimum electrode density in the border region, the sub-electrode (60) having a higher electrode density than the surroundings in the border region or the intermediate region may be placed at a specific point to increase the energy application to that point. In one embodiment, the sub-electrode (60) may be placed at a specific point in the intermediate region or at a specific point in the border region. Also, in one embodiment, the sub-electrode (60) may be in the form of a spot. Here, the spot shape may be one of a circle, an ellipse, and a polygon, but the present invention is not limited thereto.

[0119] For example, as shown in FIG. 24, a sub-electrode (60) is formed in the edge region of the electrode (20) and connected to the electrode (20) so as to generate heat on the outer edge of the electrode (20). In this way, the sub-electrode (60) can compensate for heat loss occurring on the outer edge of the electrode (20). In one embodiment, the sub-electrode (60) may be connected to the end of the second pattern (22).

[0120] Additionally, in another embodiment, a low-density region may be formed in a part of the electrode (20) where the electrode density is lower than that of the surrounding region. In this case, when the electrode (20) is output at a high frequency, the low-density region may have a lower temperature than the surrounding region. In one embodiment, the low-density region may be implemented by adding a void to a part of the electrode (20). As another example, the low-density region may be formed by reducing the electrode density of the corresponding region of the electrode (20). The low-density region may be utilized as a means to lower the temperature of a specific region selected by the user among the entire region of the electrode (20).

[0121] Additionally, in another embodiment, the electrode (20) may have different electrode densities in the central region, the intermediate region, and the edge region. Here, the electrode (20) may have a maximum electrode density in the central region, a minimum electrode density in the edge region, and an electrode density between the maximum and minimum values ​​in the intermediate region.

[0122] In another embodiment of the present invention, the electrode (20) may include a plurality of partition electrodes by one or more partition regions extending from the center of the base (10). The partition electrodes have a central region, a border region, and an intermediate region depending on the distance from the center of the base (10).

[0123] In one embodiment, there may be two or more partition electrodes within the electrode area. For example, if the electrode (20) has two partition electrodes of the same size by means of a single partition area crossing the center, the first pattern (21) may have a semicircular shape or a semi-polygonal shape. Additionally, for example, if there are two partition areas crossing the center and perpendicular to each other, the electrode (20) may have four partition electrodes. Additionally, for example, if there are three partition areas extending from the center of the base (10) and forming an angle of 120 degrees to each other, the electrode (20) may have three partition electrodes.

[0124] Additionally, in one embodiment, a plurality of partition electrodes include a first pattern (21) in a central region and a second pattern (22) in an intermediate region and a border region. The first pattern (21) and the second pattern (22) can be applied in the same manner as implemented in the single electrode described above.

[0125] By utilizing multiple partition electrodes, monopolar application is possible when the same polarity is connected, and bipolar application is possible when different polarities are connected to each partition electrode.

[0126] Hereinafter, an embodiment having a plurality of partition electrodes will be described in detail based on FIGS. 9 to 16.

[0127] In one embodiment, referring to FIG. 9, the base (10) has a partition area that crosses the central axis, and the electrode (20) may include two first patterns (21) formed between the partition areas of the base (10), and a second pattern (22) including at least one second unit electrode (22a) that is electrically connected to each of the two first patterns (21) and formed with a gap between the partition area of ​​the base (10) and the edge area of ​​the electrode (20). Here, the first pattern (21) may have a semicircular shape. In this embodiment, the first terminal (51) and the second terminal (52) may each be connected to the two first patterns (21). In this embodiment, the first pattern (21) and the second pattern (22) may be electrically connected through at least one connecting pattern (23). At least one connection pattern (23) extends in a direction away from the first pattern (21) and is formed at intervals along the circumferential direction of the inter-region and border regions of the electrode (20) and can be connected to the second pattern (22). In this embodiment, the first terminal (51) and the second terminal (52) are connected to the connection pattern (23) and can be electrically connected to the first pattern (21) and the second pattern (22) through the connection pattern (23).

[0128] In one embodiment, the connection pattern (23) of FIG. 10 may be composed of a larger number of connections than the connection pattern (23) of FIG. 9 when compared to the connection pattern (23) of FIG. 9. Through this, as the range of the high frequency output from the electrode (20) widens, the high frequency can be delivered to a wider area of ​​the skin.

[0129] In one embodiment, when compared to the first pattern (21) of FIG. 11, the first pattern (21) of FIG. 11 may have a semi-polygonal shape.

[0130] In one embodiment, compared to the connection pattern (23) of FIG. 11, the connection pattern (23) of FIG. 12 may be composed of a larger number of connections than the connection pattern (23) of FIG. 11. Through this, as the range of the high frequency output from the electrode (20) widens, the high frequency can be delivered to a wider area of ​​the skin.

[0131] In one embodiment, referring to FIG. 13, two first patterns (21) are arranged with the partition area of ​​the base (10) in between, and at least one second pattern (22) is electrically connected to each of the two first patterns (21) and can be formed with a gap between the partition area of ​​the base (10) and the border area of ​​the electrode (20). Here, the gap between the second patterns (22) can be formed to increase as it moves away from the central area of ​​the electrode (20). In this example, at least one second pattern (22) may include a bar shape.

[0132] In one embodiment, referring to FIG. 14, the width of each second pattern (22) may be formed to become narrower as it moves away from the central region of the electrode (20). Accordingly, the area of ​​the electrode formed by the second pattern (22) per unit area of ​​the inter-region and border regions of the electrode (20) may become narrower as it moves away from the central region of the electrode (20). In this example, at least one second pattern (22) may include a cone shape.

[0133] In one embodiment, referring to FIG. 15, two first patterns (21) are formed on each side of the central region of the electrode (20) with the partition region of the base (10) in between, and the second unit electrode (22a) of the second pattern (22) extends from the first pattern (21) and can be formed at intervals along the circumferential direction of the inter-region and border region of the electrode (20). In this embodiment, the electrode (20) may further include a third pattern (24) comprising at least one third unit electrode (24a). The at least one third unit electrode (24a) included in the third pattern (24) may be formed at intervals along the direction extending from the second pattern (22) to the circumferential direction of the inter-region and border region of the electrode (20) and away from the central region of the electrode (20). At this time, at least one third unit electrode (24a) formed on one of the two adjacent second unit electrodes (22a) may be formed offset from at least one third unit electrode (24a) formed on the other of the two adjacent second unit electrodes (22a).

[0134] In one embodiment, referring to FIG. 16, the third unit electrode (24a) included in the third pattern (24) may be formed in a zigzag pattern on both sides of the second unit electrode (22a) included in the second pattern (22). At this time, at least one third unit electrode (24a) formed on one of the two adjacent second unit electrodes (22a) may be formed offset from at least one third unit electrode (24a) formed on the other of the two adjacent second unit electrodes (22a).

[0135] In one embodiment, compared to the first pattern (21) of FIG. 15, the first pattern (21) of FIG. 16 may have a smaller diameter than the first pattern (21) of FIG. 15. Also, compared to the second pattern (22) of FIG. 15, the second pattern (22) of FIG. 16 may have a larger width than the second pattern (22) of FIG. 15.

[0136] Hereinafter, a method of outputting a high frequency as current is applied to an electrode in a high frequency output device according to an embodiment of the present invention will be described in detail.

[0137] In one embodiment, the high-frequency generator (30) can supply a current having the same polarity to the electrode (20) having the embodiment of FIGS. 1 to FIGS. 16 so that a monopolar type high frequency is output from the electrode (20) according to the control of the processor (40).

[0138] As another example, when the electrode (20) is equipped with a plurality of partition electrodes, the high-frequency generator (30) can supply current by connecting different polarities to each partition electrode so that a bipolar type high frequency is output from the electrode (20) under the control of the processor (40).

[0139] In addition, as another example, the processor can continuously alternate between monopolar and bipolar outputs while switching the polarity connected to multiple partition electrodes.

[0140] Hereinafter, the monopolar type high-frequency output process of the high-frequency output device according to the present invention will be described.

[0141] First, power of the same polarity is applied from a high-frequency generator (30) to the first pattern (21) and the second pattern (22) of the electrode (20).

[0142] Next, the first pattern (21) outputs a monopolar type high frequency overall, and the second pattern (22) also outputs a monopolar type high frequency. At this time, the monopolar type high frequency density output from the second pattern (22) gradually decreases as it moves away from the central region of the electrode (20) in comparison to when an edge effect occurs. As a result, as the difference between the monopolar type high frequency density output from the first pattern (21), that is, the central region of the electrode (20), and the monopolar type high frequency density output from the second pattern (22), that is, the edge region of the electrode (20), is mitigated, an edge effect does not occur in which the monopolar type high frequency density output from the intermediate region and the edge region of the electrode (20) is relatively higher than the monopolar type high frequency density output from the central region of the electrode (20). As a result, the occurrence of an edge effect is prevented when the monopolar type high frequency output of the electrode (20), thereby mitigating the uneven temperature distribution of the skin area receiving the monopolar type high frequency output from the electrode (20) and enabling thermal equilibrium.

[0143] According to the present invention, a high-frequency output device according to one embodiment of the present invention can prevent the occurrence of edge effects during high-frequency output and has the effect of mitigating uneven temperature distribution and temperature deviation of the skin area receiving the high frequency.

[0144] Although embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will understand that the present invention may be implemented in other specific forms without altering its technical concept or essential features. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive.
