Description

Technical Field

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

Background Art

[0002] Currently, skin management devices have been developed to cleanly manage the skin by removing wrinkles, restoring skin elasticity, and removing sebum. This is to make the skin look younger and contribute to an attractive appearance.

[0003] Skin management devices include a type that transmits ultrasonic waves to the skin (HIFU type), a type that transmits high frequency (RF type) to the skin, a type that transmits laser light to the skin (Optical type), and the like.

[0004] Here, in a high-frequency output device that transmits high frequency to the skin, the high frequency generated by the RF electrode is applied to the skin through the epidermis of the skin. As a result, when high frequency is transmitted to the skin, coagulative necrosis of the skin is induced, and collagen and elastic fibers of the skin are removed, and new collagen and elastic fibers can be formed. In addition, coagulative necrosis of the skin is also effective in improving skin pigmentation, acne marks, wrinkles, and the like.

[0005] High-frequency output devices can be classified into a bipolar type that includes an RF electrode of a first polarity and an RF electrode of a second polarity, and a monopolar type in which the RF electrode has a single polarity and a ground electrode is separately provided.

[0006] In the bipolar type, the current applied to the RF electrode of the first polarity is refluxed to the RF electrode of the second polarity, and high frequency is oscillated in a relatively narrow region between the RF electrode of the first polarity and the RF electrode of the second polarity, so that high frequency can be intensively applied to the skin.

[0007] In the monopolar type, the current applied to multiple RF electrodes of the same polarity is returned to a counter electrode plate coupled to another part of the skin (e.g., the abdomen or back), and high-frequency waves are oscillated over a relatively wide area between the multiple RF electrodes and the counter electrode plate. Therefore, high-frequency waves can be applied not only to the skin but also to the surrounding areas of the skin.

[0008] On the other hand, if a monopolar type is used and multiple RF electrodes are arranged alternately, and a unidirectional current is applied to the multiple RF electrodes, there is a risk that the current will cancel out due to the magnetic fields generated by the multiple RF electrodes. As a result, the current applied to the multiple RF electrodes will be deflected and flow towards the ends or center of the multiple RF electrodes, which may cause deflected oscillation.

[0009] Thus, the phenomenon in which high-frequency waves emitted from multiple RF electrodes are deflected to either the end of the intersecting electrodes or to the center of the intersecting electrodes is called the proximity effect.

[0010] However, in monopolar types, when the proximity effect occurs, the high-frequency waves emitted from multiple RF electrodes are biased and distributed only to specific areas of the skin, which reduces the effectiveness of skin improvement. [Overview of the project] [Problems that the invention aims to solve]

[0011] The present invention has been made in view of the above circumstances, and its object is to provide a high-frequency output device that can prevent the occurrence of the proximity effect when outputting a monopolar type high frequency.

[0012] Another object of the present invention is to provide a high-frequency output device that includes a patterned electrode capable of outputting at least one of monopolar high frequencies and bipolar high frequencies.

[0013] The issues that this disclosure aims to address are not limited to those mentioned above, and other issues not mentioned can be clearly understood by an average engineer from the description below. [Means for solving the problem]

[0019] Furthermore, a single first unit electrode may be positioned in the center of the base, and a plurality of second unit electrodes may be positioned on the edge of the base, with at least two of the plurality of second unit electrodes facing each other.

[0020] Furthermore, the plurality of first unit electrodes are arranged at the center of the base, and the plurality of second unit electrodes are arranged at the edge of the base. Among the plurality of second unit electrodes, two of the second unit electrodes can be arranged opposite to each other.

[0021] In addition, the power supply module can apply two currents having the same polarity to two of the second unit electrodes arranged opposite to each other in different directions.

[0022] Furthermore, the first unit electrode and the second unit electrode can be formed into at least one of a non-invasive type, a film type, and an invasive type, respectively.

[0023] In addition, the non-invasive type can include a polygonal shape or a disc shape, and the invasive type can include a needle shape.

[0024] Furthermore, the power supply module can further include a processor for controlling the power supply module so that a high-frequency pattern including at least one of a monopolar type high-frequency wave and a bipolar type high-frequency wave is output from the first unit electrode and the second unit electrode.

[0025] In addition, the high-frequency pattern can include a first single pattern that outputs only the monopolar type high-frequency wave, a second single pattern that outputs only the bipolar type high-frequency wave, a first alternating pattern in which the monopolar type high-frequency wave and the bipolar type high-frequency wave are alternately output, a second alternating pattern in which the bipolar type high-frequency wave and the monopolar type high-frequency wave are alternately output, and a simultaneous pattern in which the monopolar type high-frequency wave and the bipolar type high-frequency wave are output simultaneously.

[0026] Furthermore, the power supply module can apply two currents having the same polarity to the first unit electrode and the second unit electrode in different directions.

Furthermore, terms defined in commonly used dictionaries shall not be interpreted ideally or excessively unless explicitly defined otherwise.

[0035] Embodiments of the present invention will be described in detail below with reference to the attached drawings.

[0036] Figure 1a is a perspective view showing a high-frequency output device according to one embodiment of the present invention; Figure 1b is a block diagram showing a high-frequency output device according to one embodiment of the present invention; Figure 2 is a schematic diagram showing the state in which the first and second electrodes of the high-frequency output device according to one embodiment of the present invention output a monopolar type high frequency; Figure 3 is a schematic diagram showing the state in which the first and second electrodes of the high-frequency output device according to one embodiment of the present invention output a bipolar type high frequency; and Figures 4a to 4c are schematic diagrams showing the state in which the first and second electrodes of the high-frequency output device according to one embodiment of the present invention output a bipolar type high frequency.

[0037] As shown in Figures 1a and 1b, a high-frequency output device according to one embodiment of the present invention may include a high-frequency output device body, a handpiece 10, a base 20, a first electrode 30, a second electrode 40, a power supply module 50, and a processor 70.

[0038] The high-frequency output device body serves as the basic body of the present invention. The high-frequency output device body can be detachably coupled to the handpiece 10 and can be connected by wire or wireless. Here, the base 20 can be detachably coupled to the handpiece 10. For example, the handpiece 10 and the base 20 can be detachably coupled via a hook groove and a fixing hook. Here, the handpiece 10 may have a hook groove, and the base 20 may have a fixing hook that is detachably fixed to the hook groove. Alternatively, the handpiece 10 may have a fixing hook, and the base 20 may have a hook groove to which the fixing hook is detachably fixed.

[0039] A power supply module 50, a first cable 51, and a second cable 52 can be provided inside the main body of the high-frequency output device.

[0040] The power module 50 is responsible for applying current to the first electrode 30 and the second electrode 40. The first cable 51 can connect the power module 50 and the first electrode 30. The second cable 52 can connect to the second electrode 40.

[0041] As an example, the outer surface of the high-frequency output device body may be provided with a power button for turning the power supply module 50 on and off, and two adjustment buttons for adjusting the intensity of the current applied from the power supply module 50 to the first electrode 30 and the second electrode 40, respectively. When the power supply module 50 is turned on by user operation, current can be applied from the power supply module 50 to at least one of the first electrode 30 and the second electrode 40.

[0042] The base 20 can serve to fix the first electrode 30 and the second electrode 40. Such a base 20 can be detachably bonded to one side of the handpiece 10. For example, the base 20 may have a plate shape. The first electrode 30 and the second electrode 40 may also be provided on the base 20.

[0043] The first electrode 30 is provided on the base 20 and may include at least one first unit electrode 31a. The second electrode 40 is provided on the base 20 and may include at least one second unit electrode 32.

[0044] Referring to Figure 1b, the first unit electrode 31a and the second unit electrode 41a can be arranged alternately on the base 20. Here, one end of the first unit electrode 31a may be offset from the adjacent second unit electrode 41a, and one end of the second unit electrode 41a may be offset from the adjacent first unit electrode 31a. Also, the second unit electrode 41a may be interposed between two adjacent first unit electrodes 31a. In this way, by arranging the first unit electrode 31a and the second unit electrode 41a alternately, when a current of the same polarity is applied to the first unit electrode 31a and the second unit electrode 41a from the power supply module 50, the monopolar high-frequency output from the first unit electrode 31a and the second unit electrode 41a is not deflected to the center of the base 20. Therefore, the proximity effect, in which the monopolar high-frequency signals output from the first unit electrode 31a and the second unit electrode 41a are deflected towards the center or outer edge of the first unit electrode 31a and the second unit electrode 41a, can be prevented.

[0045] On the other hand, the power supply module 50 can prevent the proximity effect, in which monopolar high-frequency signals output from the first unit electrode 31a and the second unit electrode 41a are deflected towards the center or outer edge of the first unit electrode 31a and the second unit electrode 41a, by applying two currents having the same polarity to the first unit electrode 31a and the second unit electrode 41a in opposite directions under the control of the processor 70.

[0046] The first electrode 30 may include a first contact terminal 32 that connects the first unit electrode 31a and the power module 50.

[0047] The second electrode 40 may include a second contact terminal 42 that connects the second unit electrode 41a and the power module 50.

[0048] For example, the first contact terminal 32 and the second contact terminal 42 may be printed circuit boards (PCBs).

[0049] For example, the first unit electrode 31a may have a shape that extends perpendicularly from the first contact terminal 32 toward the second contact terminal 42. Similarly, the second unit electrode 41a may have a shape that extends perpendicularly from the second contact terminal 42 toward the second contact terminal 32. (See Figures 4b and 4c)

[0050] The present invention may further include a switching circuit. Here, a first contact terminal 32 can connect the switching circuit to a first unit electrode. A second contact terminal 42 can connect the switching circuit to a second unit electrode. The power supply module 50 can apply a current of the same polarity to a plurality of first unit electrodes 31a and a plurality of second unit electrodes 41a via the switching circuit. Furthermore, the power supply module 50 can apply a current of the same polarity to at least one of the plurality of first unit electrodes 31a and at least one of the plurality of second unit electrodes 41a via the switching circuit. The power supply module 50 can apply a current of the same polarity to at least one of the plurality of first unit electrodes 31a or at least one of the plurality of second unit electrodes 41a via the switching circuit. In addition, the power supply module 50 can apply currents of different polarities to two second unit electrodes 41a that are arranged facing each other, via the switching circuit under the control of the processor 70.

[0051] The processor 70 can control the power module 50 so that a high-frequency pattern including at least one of monopolar and bipolar high frequencies is output from the first unit electrode 31a and the second unit electrode 41a. Here, the high-frequency pattern can be transmitted to the skin.

[0052] The high-frequency pattern can include a first single pattern that outputs only monopolar high frequencies, a second single pattern that outputs only bipolar high frequencies, a first alternating pattern in which monopolar and bipolar high frequencies are output alternately, and a second alternating pattern in which bipolar and monopolar high frequencies are output alternately.

[0053] As an example, in the first single pattern, under the control of the processor 70, two currents having the same polarity but in different directions are applied from the power supply module 50 to the first unit electrode 31a and the second unit electrode 41a, so that only monopolar high-frequency waves can be output to the skin from the first unit electrode 31a and the second unit electrode 41a. (See Figure 3) Specifically, a current of the first polarity and in the first direction is applied to the first unit electrode 31a from the power supply module 50, a current of the first polarity and in a second direction different from the first direction is applied to the second unit electrode 41a from the power supply module 50, and a current of the second polarity can be applied to the counter electrode plate placed in another part of the skin from the power supply module 50. Thus, the monopolar high-frequency waves output to the skin from the first unit electrode 31a and the second unit electrode 41a can be recirculated to the counter electrode plate. As shown in Figure 2, when the power supply module 50 applies monopolar currents of the same polarity to the first unit electrode 30 and the second unit electrode 40 in opposite directions, the proximity effect can be prevented by applying monopolar currents of the same polarity to the first unit electrode 31a and the second unit electrode 41a in opposite directions. As another example, in the first single pattern, the power supply module 50 applies currents of the same polarity to either the first unit electrode 31a or the second unit electrode 41a under the control of the processor 70, so that only monopolar high-frequency waves are output to the skin from either the first unit electrode 31a or the second unit electrode 41a.

[0054] As an example, in the second single pattern, two currents of opposite polarity are applied from the power supply module 50 to the first unit electrode 31a and the second unit electrode 41a under the control of the processor 70, so that only bipolar high-frequency waves can be output to the skin from the first unit electrode 31a and the second unit electrode 41a. (See Figure 3) In this case, the first unit electrode 31a and the second unit electrode 41a can come into contact with the skin. The bipolar high-frequency waves output from the first unit electrode 31a and the second unit electrode 41a can be recirculated between the first unit electrode 31a and the second unit electrode 41a.

[0055] As an example, the first alternating pattern can be controlled by the processor 70 to alternately repeat the first single pattern and the second single pattern.

[0056] *As an example, the second alternating pattern can be controlled by the processor 70 to alternately repeat the second single pattern and the first single pattern.

[0057] The processor 70 may include a user interface that selectively receives inputs of a first single pattern, a second single pattern, a first alternating pattern, and a second alternating pattern. Here, the processor 70 can control the power supply module 50 according to the control signals input to the user interface. For example, the user interface may be a touchpad, keyboard, buttons, etc. As an example, the processor may be a microcontroller or a PLC (Programmable Logic Controller).

[0058] For example, comparing the first unit electrode 31a and the second unit electrode 41a in Figures 1a to 3, the first unit electrode 31a and the second unit electrode 41a in Figure 4a can have a greater thickness. This widens the range of high-frequency waves output from the first unit electrode 31a and the second unit electrode 41a, allowing the high-frequency waves to be applied to a wider area of ​​the skin.

[0059] *As an example, as shown in Figure 4b, the first contact terminal 32 and the second contact terminal 42 can be configured as a single unit. Here, the single first contact terminal 32 can connect the power supply unit 50 to a single first unit electrode 31, and the single second contact terminal 42 can connect the power supply unit 50 to a single second unit electrode 41.

[0060] As an example, as shown in Figure 4c, the first contact terminal 32 and the second contact terminal 42 are configured in multiple units, and the multiple first contact terminals 32 can connect the power supply unit 50 to multiple first unit electrodes 31a, and the multiple second contact terminals 42 can connect the power supply unit 50 to multiple second unit electrodes 41a, respectively. However, although Figure 4c shows an example where there are two first contact terminals 32 and two second contact terminals 42, and two first unit electrodes 31a and two second unit electrodes 41a, the present invention is not limited thereto, and there may be two or more first contact terminals 32 and second contact terminals 42, and there may also be two or more first unit electrodes 31a and second unit electrodes 41a.

[0061] In this embodiment, the multiple first contact terminals 32 can be connected in parallel to the multiple first unit electrodes 31, and the multiple second contact terminals 42 can be connected in parallel to the multiple second unit electrodes 41, respectively.

[0062] The following describes various embodiments of the high-frequency output device according to other embodiments of the present invention.

[0063] Figures 5 to 12 are schematic diagrams showing various embodiments of a high-frequency output device according to other embodiments of the present invention.

[0064] As shown in Figures 5 to 12, the first unit electrode and the second unit electrode can each be formed in at least one of the following types: non-invasive, film type, and invasive type.

[0065] Non-invasive types may include polygonal, disc-shaped, and plate-shaped forms.

[0066] For example, a non-invasive first unit electrode may have one of the following shapes: polygonal, disc-shaped, or plate-shaped. However, it is not limited to these, and may have a variety of other shapes.

[0067] Furthermore, the non-invasive second unit electrode may have one of the following shapes: polygonal, disc-shaped, or plate-shaped. However, it is not limited to these, and may have a variety of other shapes.

[0068] The invasive type may include a needle shape. For example, the first unit electrode of the invasive type may have a needle shape. Also, the second unit electrode of the invasive type may have a needle shape.

[0069] The film type may consist of an electrode film surrounding the base 20, or the base 20 itself may be the electrode film, with a first unit electrode and a second unit electrode arranged on such an electrode film. For example, the first unit electrode of the film type may be located on the inner surface of the electrode film. Therefore, when viewed from the outside of the handpiece 10, the first unit electrode of the film type may have a shape covered by the electrode film. The second unit electrode of the film type may be located on the outer surface of the electrode film.

[0070] The power module 50 can apply a current of the same polarity to at least one of the multiple first unit electrodes via the first cable 51 under the control of the switching circuit of the processor 70, and at the same time, it can apply a current of the same polarity as the current applied to the first unit electrode to at least one of the multiple second unit electrodes via the second cable 52. Furthermore, the power module 50 can apply currents of different polarities to two second unit electrodes that are arranged facing each other, under the control of the processor 70.

[0071] As an example, the power supply module 50 can apply two currents with the same polarity to a first unit electrode and a second unit electrode, which are arranged facing each other, in opposite directions, by the control of the switching circuit of the processor 70.

Specifically, four second unit electrodes 41c may be positioned at the first, second, third, and fourth corners of the base 20, respectively. Here, the first corner may be located on the upper left side of the base 20, the second corner on the upper right side of the base 20, the third corner on the lower left side of the base 20, and the fourth corner on the lower right side of the base 20. Here, the first unit electrode 31c and the second unit electrodes 41c may be formed in a non-invasive manner. Specifically, referring to Figure 7, the first unit electrode 31c may have a plate shape, and the second unit electrode 41c may have a triangular shape. Also, referring to Figure 8, the first unit electrode 31c may have a plate shape, and the second unit electrode 41c may have an arc shape.

[0075] Referring to Figure 9, a single first unit electrode 31d is positioned in the center of the base 20, and two second unit electrodes 41d may be positioned in the frame of the base 20, facing each other in a first or second direction. Here, the first unit electrode 31d and the second unit electrodes 41d may be formed in a non-invasive manner. Specifically, referring to Figure 9, the first unit electrode 31d and the second unit electrodes 41d may have a plate-like shape.

[0076] In one embodiment, referring to Figures 10 to 12, a plurality of first unit electrodes 31e are arranged in the center of the base 20, a plurality of second unit electrodes 41e are arranged in the frame of the base 20, and two of the plurality of second unit electrodes 41e may be arranged facing each other.

[0077] Referring to Figure 10, a plurality of first unit electrodes 31e are arranged in a second direction in the center of the base 20, and a plurality of second unit electrodes 41e may be arranged as in the embodiments of Figures 6 and 7. Here, the first unit electrodes 31e and the second unit electrodes 41e can be formed in a non-invasive manner. Specifically, referring to Figure 10, the first unit electrodes 31e and the second unit electrodes 41e may have a plate-like shape.

[0078] Referring to Figure 11, a plurality of first unit electrodes 31e are arranged in a first direction in the center of the base 20, and a plurality of second unit electrodes 41e may be arranged as in the embodiments of Figures 6 and 7.

Specifically, referring to Figure 12, the first unit electrodes 31e and the second unit electrodes 41e may have a plate-like shape.

[0080] In this embodiment, the processor 70 can control the power module 50 so that a high-frequency pattern including at least one of monopolar high-frequency and bipolar high-frequency is output from the first unit electrodes 31b-31e and the second unit electrodes 41b-41e. Here, the high-frequency pattern can be transmitted to the skin.

[0081] In this embodiment, the high-frequency pattern can include a first single pattern that outputs only monopolar high frequencies, a second single pattern that outputs only bipolar high frequencies, a first alternating pattern in which monopolar and bipolar high frequencies are output alternately, a second alternating pattern in which bipolar and monopolar high frequencies are output alternately, and a simultaneous pattern in which bipolar and monopolar high frequencies are output simultaneously.

[0082] As an example, in the first single pattern, the processor 70 controls the application of two currents from the power supply module 50 to the first and second unit electrodes, which have the same polarity but different directions, so that only monopolar high-frequency waves can be output to the skin from the first and second unit electrodes. Alternatively, the first unit electrode may be supplied with a current of the first polarity and in the first direction from the power supply module 50, the second unit electrode may be supplied with a current of the first polarity and in the second direction different from the first direction from the power supply module 50, and the counter electrode plate, which is placed in another part of the skin, may be supplied with a current of the second polarity from the power supply module 50. Thus, the monopolar high-frequency waves output to the skin from the first and second unit electrodes can be recirculated to the counter electrode plate.

[0083] As another example, in the first single pattern, the processor 70 controls the application of a current of the same polarity from the power module 50 to the first unit electrode or the second unit electrode, thereby enabling the output of only monopolar high-frequency waves to the skin from the first unit electrode or the second unit electrode.

[0084] In the second single pattern, the processor 70 controls the application of two currents of different polarities from the power supply module 50 to two second unit electrodes positioned opposite each other, thereby enabling the output of only bipolar high-frequency waves to the skin from the two opposing second unit electrodes. In this case, the two opposing second unit electrodes can contact or penetrate the skin. The bipolar high-frequency waves output from the two opposing second unit electrodes can be recirculated between the two opposing second unit electrodes.

[0085] The first alternating pattern can be controlled by the processor 70 to alternately repeat the first single pattern and the second single pattern.

[0086] The second alternating pattern allows the second single pattern and the first single pattern to be repeated alternately under the control of the processor 70.

[0087] In the simultaneous pattern, the processor 70 controls the application of a current of the same polarity from the power module 50 to the first unit electrode, and two currents of different polarities are applied to two second unit electrodes positioned opposite each other. As a result, monopolar high-frequency waves are output to the skin from the first unit electrode, and at the same time, bipolar high-frequency waves are output to the skin from the two second unit electrodes positioned opposite each other.

[0088] In this embodiment, the processor 70 may include a user interface that selectively receives inputs of a first single pattern, a second single pattern, a first alternating pattern, a second alternating pattern, and a simultaneous pattern. Here, the processor 70 can control the power supply module 50 in accordance with the control signals input to the user interface. For example, the user interface may be a touchpad, a keyboard, buttons, etc.

[0089] According to the present invention, a high-frequency output device according to one embodiment of the present invention has the effect of preventing the occurrence of the proximity effect when outputting a monopolar type high frequency.

[0090] Furthermore, the high-frequency output device according to one embodiment of the present invention has the effect of being able to output at least one of monopolar high frequencies and bipolar high frequencies.

Accordingly, the embodiments described above should be understood in all respects as illustrative and not restrictive.
