[0043] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0044] FIG. 1 is a perspective view showing a high-frequency output device according to one embodiment of the present invention, and FIG. 2 is a cross-sectional view showing a high-frequency output device according to one embodiment of the present invention.

[0045] As shown in FIGS. 1 and 2, a high-frequency output device according to one embodiment of the present invention may include a main body (10), a film (20), and an electrode (30).

[0046] The main body (10) serves as the basic body of the present invention and can be utilized as a handle for the user's grip. This main body (10) can be defined as a handpiece. In addition, the main body (10) can be provided with a power module (40), a first cable (41), a second cable (42), and a processor (50).

[0047] The power module (40) serves to apply current to the electrode (30). The first cable (41) can connect the power module (40) and the second unit electrode (32a). The second cable (42) can connect the power module (40) and the first unit electrode (31a).

[0048] For example, the power module (40) may include a switching circuit for supplying power to at least one of the second unit electrode (32a) and the first unit electrode (31a). Here, the first cable (41) may be configured in plurality, and the plurality of first cables (41) may connect the switching circuit to the plurality of second unit electrodes (32a), respectively. The second cable (42) may be configured in plurality, and the plurality of second cables (42) may connect the switching circuit to the plurality of first unit electrodes (31a), respectively. Here, the power module (40) may apply current of the same polarity to the plurality of second unit electrodes (32a) and the plurality of first unit electrodes (31a) through the switching circuit. In addition, the power module (40) may apply current of the same polarity to at least one of the plurality of second unit electrodes (32a) and at least one of the plurality of first unit electrodes (31a) through the switching circuit. In addition, the power module (40) can apply current of the same polarity to at least one of the plurality of second unit electrodes (32a) or at least one of the plurality of first unit electrodes (31a) through a switching circuit. In addition, the power module (40) can apply current of different polarities to two first unit electrodes (31a) that are arranged opposite to each other among the plurality of first unit electrodes (31a) through a switching circuit.

[0049] A film (20) may be provided on the main body (10) and may serve to fix the electrode (30). In addition, the film (20) may have thermal conductivity. In this way, the film (20) conducts heat generated from the electrode (30), thereby preventing burns from occurring on the skin that comes into contact with or is close to the electrode (30) due to overheating of the electrode (30) when the electrode (30) applies high frequency to the skin.

[0050] For example, the film (20) may include a thermally conductive material. For example, the thermally conductive material may include at least one of epoxy, urethane, and silicone, and more preferably, silicone.

[0051] As another example, the film (20) may include an insulating material to act as a dielectric material.

[0052] The electrode (30) may be formed on at least one of the first side and the second side, which is the back side of the first side, of the film (20), and may serve to output high frequency waves to the skin. Here, the first side of the film (20) may be a side of the film (20) that faces the skin, and the second side of the film (20) may be a side of the film (20) that faces the main body (10). In addition, the first side of the film (20) may be an outer side of the film (20), and the second side of the film (20) may be an inner side of the film (20).

[0053] The electrode (30) can output high frequency to the skin through power supplied from the power module (40).

[0054] Referring to FIGS. 1 and 2, the electrode (30) may include a plurality of first unit electrodes (31a) and at least one second unit electrode (32a). Here, the plurality of first unit electrodes (31a) may be coupled to the first surface of the film (20) with a gap therebetween. And, at least two of the plurality of first unit electrodes (31a) may be arranged to face each other. At least one second unit electrode (32a) may be coupled to the second surface of the film (20).

[0055] Referring to FIGS. 1 and 2, the first unit electrode (31a) can be placed in a non-overlapping area of ​​the film (20) that does not collide with the second unit electrode (32a). Accordingly, interference between the high frequency output from the second unit electrode (32a) to the skin and the first unit electrode (32a) can be prevented.

[0056] For example, the first unit electrode (31a) and the second unit electrode (32a) may have a plate shape, and preferably, a flat film shape. Accordingly, the second unit electrode (32a) may be positioned facing the skin, and the first unit electrode (31a) may be brought into contact with the target area of ​​the skin.

[0057] For example, when a bipolar type high frequency is output to the skin from a plurality of first unit electrodes (31a) and a monopolar type high frequency is output to the skin from at least one second unit electrode (32a), the bipolar type high frequency may increase the temperature of the epidermis of the skin or flow to the epidermis of the skin, and the efficiency with which the monopolar type high frequency is transmitted to the skin may be improved due to the increase in temperature. In addition, since the bipolar type high frequency outputs high frequency energy from the epidermis of the skin, it may stimulate the epidermis and upper part of the dermis of the skin, thereby providing the effect of restoring skin elasticity and removing freckles.

[0058] For example, when a monopolar type high frequency is output to the skin from a plurality of first unit electrodes (31a) and a monopolar type high frequency is output to the skin from at least one second unit electrode (32a), the monopolar type high frequency output from the plurality of first unit electrodes (31a) increases the deep temperature of the skin, thereby reducing the impedance (resistance) of the epidermis of the skin, thereby increasing the depth at which the monopolar type high frequency output from the at least one second unit electrode (32a) is transmitted to the skin, and thus the effects of lifting and fat reduction can occur. In addition, the monopolar type high frequency output from the at least one second unit electrode (32a) increases the temperature of the upper dermis, dermis, and fat layer of the skin, and thus the depth at which the monopolar type high frequency output from the first unit electrode (31a) is transmitted to the skin can increase.

[0059] The electrode (30) can receive power from the power module (40) under the control of the processor (50).

[0060] The processor (50) can control the power module (40) so that a high-frequency pattern including at least one of a monopolar type high-frequency pattern and a bipolar type high-frequency pattern is output from the first unit electrode (31a) and the second unit electrode (32a). Here, the high-frequency pattern can be transmitted to the skin.

[0061] The high-frequency pattern output from at least one of the first unit electrode (31a) and the second unit electrode (32a) may include, but is not limited to, a first single pattern in which only monopolar type high-frequency is output, a second single pattern in which only bipolar type high-frequency is output, a first alternating pattern in which monopolar type high-frequency and bipolar type high-frequency are output alternately, a second alternating pattern in which bipolar type high-frequency and monopolar type high-frequency are output alternately, or a simultaneous pattern in which bipolar type high-frequency and monopolar type high-frequency are output simultaneously.

[0062] For example, the first single pattern can output only a monopolar type high frequency to the skin from the first unit electrode (31a) and the second unit electrode (32a) by applying currents of the same polarity to the first unit electrode (31a) and the second unit electrode (32a) from the power module under the control of the processor (50). Specifically, the first unit electrode (31a) and the second unit electrode (32a) are arranged to contact or face the skin, and the counter electrode plate is in contact with a different part of the skin, and the power module can apply a current of the first polarity to the first unit electrode (31a) and the second unit electrode (32a) and apply a current of the second polarity to the counter electrode plate. Therefore, the monopolar type high frequency output to the skin from the first unit electrode (31a) and the second unit electrode (32a) can be refluxed to the counter electrode plate.

[0063] As another example, the first single pattern can output only a high frequency of monopolar type to the skin from the first unit electrode (31a) or the second unit electrode (32a) by applying a current of the same polarity from the power module to the first unit electrode (31a) or the second unit electrode (32a) under the control of the processor (50). At this time, the electrode plate can be in contact with another part of the skin.

[0064] For example, the second single pattern may output only a bipolar type high frequency to the skin from the two first unit electrodes (31a) that are positioned opposite to each other as two currents of different polarities are applied to the two first unit electrodes (31a) that are positioned opposite to each other from the power module under the control of the processor (50). At this time, the two first unit electrodes (31a) that are positioned opposite to each other may contact or invade the skin. In addition, the bipolar type high frequency output from the two first unit electrodes (31a) that are positioned opposite to each other may circulate between the two first unit electrodes (31a) that are positioned opposite to each other.

[0065] For example, the first alternating pattern may alternately repeat a first single pattern and a second single pattern under the control of the processor (50). In other words, the first alternating pattern may alternately repeat a first single pattern in which a current of the same polarity is applied from the power module to at least one of the first unit electrode (31a) and the second unit electrode (32a) and a second single pattern in which two currents of different polarities are applied to two first unit electrodes (31a) that are arranged opposite to each other from the power module under the control of the processor (50).

[0066] For example, the second alternating pattern may alternately repeat a second single pattern and a first single pattern under the control of the processor (50). In other words, the second alternating pattern may alternately repeat a second single pattern in which two currents of different polarities are applied to two first unit electrodes (31a) that are arranged opposite to each other from the power module, and a first single pattern in which a current of the same polarity is applied to at least one of the first unit electrode (31a) and the second unit electrode (32a) from the power module under the control of the processor (50).

[0067] For example, a simultaneous pattern is such that two currents of different polarities are applied to two first unit electrodes (31a) positioned opposite each other from a power module under the control of a processor (50), and a current of the same polarity is applied to a second unit electrode (32a), so that a bipolar type high frequency can be output to the skin from the two first unit electrodes (31a) positioned opposite each other, and a monopolar type high frequency can be output to the skin from the second unit electrode (32a) at the same time.

[0068] The processor (50) increases the temperature of the skin and reduces the impedance (resistance) of the skin by repeating the first alternating pattern, the second alternating pattern, and the simultaneous pattern, so that the depth at which high frequency is transmitted to the skin can be increased, and as the efficiency of high frequency transmission to the skin is improved, a skin regeneration effect can be obtained with low output.

[0069] The processor (50) may include a user interface that selectively receives a first single pattern, a second single pattern, a first alternating pattern, a second alternating pattern, and a simultaneous pattern. Here, the processor (50) may control the power module (40) according to a control signal input to the user interface. For example, the user interface may use a touch pad, a keyboard, buttons, etc. As an example, the processor (50) may be a microcomputer or a PLC (Programmable Logic Controller).

[0070] A high frequency output device according to one embodiment of the present invention may further include a cooling module (60).

[0071] The cooling module (60) can cool at least one of the film (20) and the plurality of electrodes (30).

[0072] For example, the cooling module (60) may include a cooling nozzle (61) that sprays a cooling fluid onto at least one of the film (20) and the electrode (30). Here, the cooling nozzles (61) are configured in plurality, and the plurality of cooling nozzles (61) may spray the cooling fluid onto the film (20) and the second unit electrode (32a). For reference, the plurality of cooling nozzles (61) may receive the cooling fluid from a cooler.

[0073] For example, the cooling module (60) may include a sprinkler cooler (not shown) that sprays cooling fluid onto at least one of the film and the plurality of electrodes.

[0074] In this way, by cooling the film (20) and the electrode (30) by the cooling module (60), overheating of the electrode (30) can be prevented and burns can be prevented from occurring on the skin that comes into contact with or is close to the electrode (30).

[0075] Hereinafter, various modifications of a high-frequency output device according to an embodiment of the present invention will be described, excluding the configuration described in the embodiment of the present invention, and configurations different from the embodiment of the present invention.

[0076] Fig. 3 is a cross-sectional view showing a first modified example of a high-frequency output device according to one embodiment of the present invention.

[0077] Referring to FIG. 3, in this modified example, the electrode (30) may include a plurality of first unit electrodes (31b) and at least one second unit electrode (32b). Here, the plurality of first unit electrodes (31b) may be coupled to the first surface of the film (20) with a gap therebetween. And, at least two of the plurality of first unit electrodes (31b) may be arranged to face each other. In addition, at least one second unit electrode (32b) may be coupled to the second surface of the film (20).

[0078] Referring to FIG. 3, in this modified example, the first unit electrode (31b) can be placed in a non-overlapping area that does not collide with the second unit electrode (32b) in the film (20). Accordingly, interference between the high frequency output from the second unit electrode (32b) to the skin and the first unit electrode (32b) can be prevented.

[0079] In this modified example, the first unit electrode (31b) has a needle shape, and the second unit electrode (31b) may have a plate shape of a non-invasive type, and preferably may have a flat film shape. Accordingly, the first unit electrode (31b) may be invasive to the skin, and the second unit electrode (32b) may be positioned facing the skin or in contact with the skin.

[0080] In this modified example, the depth at which the plurality of first unit electrodes (31b) penetrate the skin can be adjusted. For example, the depth at which the plurality of first unit electrodes (31b) penetrate the skin can be adjusted by a user holding the main body (10). In another example, the main body (10) is provided to be reciprocally movable by an actuator, so that the depth at which the plurality of first unit electrodes (31b) penetrate the skin can be adjusted.

[0081] In this modified example, when a bipolar type high frequency is output from a plurality of first unit electrodes (31b) to the deep skin, the bipolar type high frequency output from the plurality of first unit electrodes (31b) flows between the deep skin portions where the plurality of first unit electrodes (31b) have penetrated, electrically stimulating skin tissue, and may produce effects of removing freckles, skin elasticity, pores, and fine wrinkles. In addition, the bipolar type high frequency output from the plurality of first unit electrodes (31b) may increase the temperature of skin tissue and induce skin cell stimulation.

[0082] In this modified example, when a monopolar type high frequency is output to the skin from a plurality of first unit electrodes (31b) and at least one second unit electrode (32b), the monopolar type high frequency output from the plurality of first unit electrodes (31b) increases the temperature of the deep skin portion where the plurality of first unit electrodes (31b) have penetrated, flows into the deep skin portion and reduces the impedance (resistance) of the deep skin portion, and electrically stimulates the skin tissue, and can transmit the monopolar type high frequency output from the at least one second unit electrode (32b) to the skin more deeply and widely into the skin.

[0083] Fig. 4 is a cross-sectional view showing a second modified example of a high-frequency output device according to one embodiment of the present invention.

[0084] As illustrated in FIG. 4, in this modified example, the electrode (30) may include a plurality of first unit electrodes (31c) arranged at equal intervals on the first surface of the film (20).

[0085] In this modified example, the plurality of first unit electrodes (31c) may have a protruding shape, preferably a disc shape. Accordingly, the first unit electrodes (31c) can be brought into contact with the skin.

[0086] In this modified example, the power module (40) can apply current of the same polarity to at least one of the plurality of first unit electrodes (31c) through a switching circuit. In addition, the power module (40) can apply current of different polarities to two first unit electrodes (31c) that are arranged opposite to each other among the plurality of first unit electrodes (31c) through the switching circuit.

[0087] In this modified example, the cooling module (60) may include a cooling nozzle (61) that sprays a cooling fluid onto the film (20). Accordingly, the cooling fluid sprayed onto the film (20) can quickly cool the first unit electrode (31c) through the film (20). As a result, when a bipolar type current or a monopolar type current is applied from the plurality of first unit electrodes (31c) to the skin, even if high energy is used for the plurality of first unit electrodes (31c), a burn can be prevented from occurring on the skin that the plurality of first unit electrodes (31c) come into contact with.

[0088] FIG. 5 is a cross-sectional view showing a third modified example of a high-frequency output device according to one embodiment of the present invention, and FIG. 6 is a perspective view showing a third modified example of a high-frequency output device according to one embodiment of the present invention.

[0089] As illustrated in FIGS. 5 and 6, in this modified example, the electrode (30) may include a plurality of first unit electrodes (31d) spaced apart from each other on the first surface of the film (20) and a plurality of second unit electrodes (32d) extending toward the skin from the plurality of first unit electrodes (31d).

[0090] In this modified example, the first unit electrode (31d) may have a shape protruding from the film (20) (see FIG. 5), and preferably may have a disk shape. Here, the second unit electrode (32d) may have a needle shape.

[0091] In this modified example, the first unit electrode (31d) may have a plate shape (see FIG. 6), and preferably may have a flat film shape. Here, the second unit electrode (32d) may have a needle shape.

[0092] In this modified example, the first unit electrode (31d) and the second unit electrode (32d) can be formed as an integral body. Accordingly, after the second unit electrode (32d) is invasive into the skin, the first unit electrode (31d) can come into contact with the skin.

[0093] In this modified example, the first unit electrode (31d) and the second unit electrode (32d) are in contact with the skin (non-invasive) and invasively invasively, respectively, so that high frequency is transmitted from the skin epidermis to the upper part of the skin dermis at once, thereby shortening the time for transmitting high frequency to the skin.

[0094] FIG. 7 and FIG. 8 are cross-sectional views showing a fourth modified example of a high-frequency output device according to one embodiment of the present invention.

[0095] As shown in FIGS. 7 and 8, in this modified example, the high-frequency output device includes an adapter (33) that is provided to be reciprocally movable on the main body (10), a film (20) fixed to the adapter (33), and a plurality of through holes (21) formed at intervals in the film (20), and some of the plurality of electrodes (30) may be protruded from the through holes (21) according to the reciprocal movement of the adapter (33).

[0096] In this modified example, the electrode (30) may include a plurality of first unit electrodes (31e) spaced apart from each other on the first surface of the film (20) and a plurality of second unit electrodes (32e) that penetrate the through-hole (21) and can protrude from the through-hole (21) according to the reciprocating movement of the adapter (33). Here, one end of the second unit electrode (32e) may be coupled to the adapter (33), and the other end of the second unit electrode (32e) may be penetrated into the through-hole (21). In addition, the length at which the plurality of second unit electrodes (32e) protrude from the through-hole (21) according to the reciprocating movement of the adapter (33) may be adjusted, and thereby the depth at which the plurality of second unit electrodes (32e) are invasive into the skin may be adjusted.

[0097] In this modified example, the adapter (33) may be provided to be reciprocally movable in the direction of insertion into the main body (10) or in the direction of discharge from the main body (10) by an actuator provided in the main body (10).

[0098] In this modified example, the first unit electrode (31e) may have a needle shape, and the second unit electrode (32e) may have a plate shape, preferably a film shape. Accordingly, the first unit electrode (31e) may be invasive to the skin, and the second unit electrode (32e) may be in contact with the skin.

[0099] In this modified example, when a bipolar type high frequency is output from a plurality of first unit electrodes (31e) to the skin epidermis, the bipolar type high frequency output from the plurality of first unit electrodes (31e) can increase the temperature of skin tissue and induce skin cell stimulation.

Here, one end of the second unit electrode (32f) may be coupled to the adapter (33), and the other end of the second unit electrode (32f) may be penetrated through the through-holes (21) and the connecting holes (31h). In addition, the length at which the plurality of second unit electrodes (32f) protrude from the through-holes (21) according to the reciprocating movement of the adapter (33) may be adjusted, and thereby the depth at which the plurality of second unit electrodes (32f) are invasive into the skin may be adjusted.
