Technical Field

[0001] The present invention relates to a high-frequency current output device, and more particularly, when high-frequency is transmitted to the skin, a monopolar type and a bipolar type pattern 、 or a bipolar type and a monopolar type pattern 、 are sequentially or continuously transmitted to increase collagen, elastin, etc. The present invention relates to a device for this.

[0004] As methods of transmitting high-frequency energy, the monopolar (unipolar, monopolar) type and the bipolar (bipolar, bipolar) type are the most common, and a monopolar type or a bipolar type is selectively used according to the High-frequency irradiation depth of the skin with one operating device.

[0005] Thus, the mechanism using high-frequency High-frequency irradiation can be explained in two ways.

[0006] The first is to induce contraction of the entire skin and subcutaneous tissue by heating the collagen fibers in the dermis, and the second is to promote the regenerative property of collagen through coagulative denaturation of collagen.

[0007] The bipolar type has limited heating amount and penetration depth But whereas the monopolar type can use a sufficient amount of energy deeper.

[0008] Bipolar iontophoresis is primarily effective for treating blemishes, dilated capillaries, enlarged pores, and mild wrinkles, while monopolar iontophoresis is known to be effective in improving wrinkles and skin sagging.

[0009] Thus, bipolar and monopolar types differ in the depth to which high-frequency energy is transmitted. High-frequency irradiation They are selected and used according to their purpose.

[0010] However, when selecting a pattern that combines two or more of these types, an additional operation is required to switch from monopolar to bipolar or from bipolar to monopolar. No device was supplied that could output monopolar and bipolar or bipolar or monopolar simultaneously or with a short relay time in a single operation.

[0011] Furthermore, in one high-frequency current output device 、 While monopolar and bipolar types can be selected and used, the monopolar type had a problem in that, if the same polarity was applied to the entire needle, electrode bias would occur due to the proximity effect of the needle.

[0042] Please refer to the attached drawings below. while The embodiments of the present invention will now be described in detail.

[0043] Figure 1 is a block diagram showing a system including a high-frequency current output device 1000 according to one embodiment of the present invention, Skincare device The system includes a 100, a handpiece 200, an electrode unit 300, and a high-frequency current output device 1000.

[0044] In this case, the components of the high-frequency current output device 1000 described above are either integrated into a single body, or at least some of the components are separated from each other, but these separated components can transmit and receive signals from each other via wired communication or wireless communication.

[0045] Skincare device 100 includes a first high-frequency power generation unit 110, a second high-frequency power generation unit 120, a switching circuit 130, and a control unit 140.

[0046] At this time, Skincare deviceAt 100, basically only the first high-frequency power generation unit 110 is driven, and the second high-frequency power generation unit 120 is additionally driven to prevent interference effects between multiple closely spaced electrodes in the electrode unit 300.

[0047] Here, the second high-frequency power generation unit 120 is connected to a separate electrode from the first high-frequency power generation unit 110 to supply current.

[0048] Furthermore, the electrode section 300 has multiple electrodes electrically connected to the needle tip, i.e. 、 Multiple first electrodes 3 10-1 to 310-N Reach and multiple second electrodes 3 20-1 to 320-N of include.

[0049] Figure 2 is shown in Figure 1. Skincare device This is an internal block diagram of a switching circuit 130 within 100, which includes a distributor 131 and a relay 132.

[0050] The control unit 140 is based on the present invention. Skincare device A memory for storing data for an algorithm or a program that reproduces the algorithm for controlling the operation of the first high-frequency power generation unit 110, the second high-frequency power generation unit 120, and the switching circuit 130 within 100, and a memory for storing data for a program that reproduces the algorithm, and a memory for using the data stored in the memory to perform the operation described later. either It can be implemented with a single processor (not shown).

[0051] Here, the first high-frequency power generation unit 110 and the second high-frequency power generation unit 120 are shown to be separated in order to show equal output between the electrodes.

[0052] In other words, the basic switching operation of the switching circuit 130 of the present invention is performed only through either the first high-frequency power generation unit 110 or the second high-frequency power generation unit 120. High-frequency irradiation The electrode connection inside is designed to perform switching between the RF electrode and the counter electrode plate (NE Pad).

[0053] Specifically, when the first electrode 310-N and the second electrode 320-N are located in the electrode section 300, in the monopolar type, the first electrode 310-N and the second electrode 320-N are connected to the same polarity [for example, (+)], and the opposite polarity [for example, (-)] is connected to the counter electrode plate. When switching to the bipolar type, the second electrode 320-N is connected to the opposite polarity, and the connection to the counter electrode plate is broken.

[0054] Furthermore, by providing a monopolar output, even if the first electrode 310-N and the second electrode 320-N are connected with the same polarity, the rapid on / off switching operation of the switching circuit 130 ensures that power is supplied to the first electrode 310-N and the second electrode 320-N in different sections.

[0055] This reduces the skin effect, where energy is concentrated on the outside due to the close spacing between electrodes in a monopolar design.

[0056] In order to reduce the delay in switching between the first electrode 310-N and the second electrode 320-N in a monopolar type based on this operating principle, the present invention further includes a second high-frequency power supply generation unit 120 in addition to the first high-frequency power supply generation unit 110. In the case of monopolar, the first electrode 310-N and the second electrode 320-N are connected to the respective high-frequency power supply generation units, and the delay is reduced when they are displayed alternately.

[0057] In this case, the separation of the first high-frequency power generation unit 110 and the second high-frequency power generation unit 120 can be additionally applied to prevent interference effects between multiple adjacent electrodes in the electrode unit 300 when performing alternating monopolar output.

[0058] Smooth alternating output between bipolar and monopolar types is made possible by the switching circuit 130.

[0059] The control unit 140, when a bipolar current is output after a monopolar current has been output, first figure,When a monopolar current is output, the control unit 140 controls the switching operation of the switching circuit 130 so that the first polarity electrode of the first high-frequency power generation unit 110 is connected to the first electrode 310-N and the second electrode 320-N, and the second polarity electrode of the first high-frequency power generation unit 110, which is opposite to the first polarity electrode of the first high-frequency power generation unit 110, is connected to the counter electrode plate (NE Pad), so that current flows between the first electrode 310-N and the second electrode 320-N and the counter electrode plate (NE Pad). Subsequently, when a bipolar current is output, the control unit 140 controls the switching operation of the switching circuit 130 so that the second polarity electrode of the first high-frequency power generation unit 110 is connected to the counter electrode plate (NE Pad) and then to the second electrode 320-N, so that current flows between the first electrode 310-N and the second electrode 320-N. On the other hand, when a monopolar current is output after a bipolar current has been output, the control unit 140 controls the previous description Note did The process can be controlled in reverse.

[0060] The electrode section 300 is skin It can be configured to output current directly or indirectly.

[0061] skin teeth Tighten, Acne, pigmentation This can refer to skin that has been treated with radiofrequency irradiation to address deposition. .

[0062] The electrode section 300 is composed of one or more first electrodes and one or more second electrodes.

[0063] When a current of the same polarity is applied to the first electrode 310-N and the second electrode 320-N of the electrode section 300, a monopolar type is formed, and when currents of different polarities are applied to the first electrode 310-N and the second electrode 320-N, a bipolar type is formed.

[0064] A monopolar type can refer to a type that outputs a single polarity from its electrodes.

[0065] A monopolar type can refer to an output configuration of multiple electrodes that, when high-frequency current is passed from one electrode, recirculates the same high-frequency current from a ground electrode in contact with the skin at a separate location.

[0066] The term "bipolar" can refer to a type of device that outputs different polarities from its electrodes.

[0067] A bipolar type can refer to an output configuration of multiple electrodes in which high-frequency energy is applied to the skin from the positive electrode and then recirculated from the negative electrode located around it.

[0068] Bipolar radios have two electrodes placed close together and use high-frequency waves to narrow the affected area and define a specific range. High-frequency irradiation It can be implemented so that areas other than the target area are not affected by high-frequency waves.

[0069] This invention aims to improve skin tightening effects by using both monopolar and bipolar types, and each type is used for skin tightening. High-frequency irradiation The role it plays in this process will be explained later.

[0070] The electrode portion 300 can be generated using an invasive microneedle, and multiple non-invasive electrodes are also possible.

[0071] According to one embodiment of the present invention, when an invasive electrode is formed with a plurality of microneedles, the thickness of each microneedle can be within the range of 0.15 mm to 1.0 mm, but it is most preferable that it be within the range of 0.15 mm to 0.35 mm.

[0072] At this time, the first and second high-frequency power generation units 110 and 120 from The current supplied is used to raise the temperature of the activated region (i.e., the target site) at a depth where it is electromagnetically energized beneath the skin surface through a microneedle to a level where the tissue is heated. However, the microneedles include non-insulated needles, needles with an activated region formed at the terminal end, and needles containing multiple activated regions at a specific identical location. 、It can be manufactured in a variety of forms.

[0073] Furthermore, the same applies when the electrode section 300 is composed of multiple non-invasive electrodes as when it is composed of microneedles. to The temperature of the target area is increased by the heating of the tissue. So It is used to raise something to a certain level.

[0074] In this case, the size of each of the multiple electrodes is preferably determined within the range of 0.16 mm to 3 cm, and most preferably within the range of 0.16 mm to 10 mm.

[0075] Furthermore, the height of each of the multiple electrodes can be generated within the range of 0 mm to 50 mm, and it is preferable that they be generated within the range of 0 mm to 10 mm.

[0076] On the other hand, according to one embodiment, a film provided to cover the electrode portion 300 may be further included.

[0077] At this time, the area of ​​the film is 0.25 cm². 2 ~25cm 2 It can be generated within the range.

[0078] The control unit 140 controls at least one of the first high-frequency power generation unit 110 and the second high-frequency power generation unit 120. either Based on a power source generated from one, the current from the two electrodes is transmitted to the electrode section 300. 、 Multiple electrodes either output a monopolar current or transmit currents of different polarities to the first electrode 310-N and the second electrode 320-N. 、 The aforementioned multiple electrodes can be controlled to output a bipolar current.

[0079] Specifically, when the control unit 140 outputs a bipolar current using the first high-frequency power generation unit 110, it outputs currents of different polarities to the first electrode 310-N and the second electrode 320-N, and an alternating current can be applied.

[0080] In this case, basically only the first high-frequency power generation unit 110 is driven, and the second high-frequency power generation unit 120 can be additionally driven to prevent interference effects between multiple adjacent electrodes in the electrode unit 300.

[0081] Furthermore, when the control unit 140 outputs a bipolar current using the second high-frequency power generation unit 120, it can output currents of different polarities to the first electrode 310-N and the second electrode 320-N, and an alternating current can be applied.

[0082] The same applies in this case as well. to Basically, only the first high-frequency power generation unit 110 is driven, As stated For this purpose, a second high-frequency power generation unit 120 can be additionally driven.

[0083] On the other hand, even when the control unit 140 outputs a monopolar current, basically only the first high-frequency power supply generation unit 110 is driven, As stated For this purpose, a second high-frequency power generation unit 120 can be additionally driven.

[0084] In this case, the first electrode 310-N and the second electrode 320-N will output currents of the same polarity, and an alternating current can be applied.

[0085] On the other hand, if a monopolar output is provided to the electrode section 300, a counter electrode plate (NE Pad) connected with a polarity different from the polarity applied to the electrode section 300 is required.

[0086] On the other hand, when the control unit 140 outputs current of each type 、 The relay 132 included in the switching circuit 130 can be operated.

[0087] When the distributor 131 and relay 132 included in the switching circuit 130 are operating, an interval of up to 500ms may occur between outputs.

[0088] On the other hand, the control unit 140 outputs monopolar and bipolar signals, and can select the same or different frequencies for each output.

[0089] Furthermore, the control unit 140 can have the following output patterns, in which monopolar and bipolar currents are combined and output simultaneously or sequentially according to the output setting pattern.

[0090] In other words, the control unit 140 controls monopolar and bipolar currents to be output simultaneously or sequentially according to an output setting pattern that is selected by the user or automatically set.

[0091] In this case, a monopolar current raises the temperature of the current supply region overall, while a bipolar current raises the temperature of a local region locally by supplying energy to that local region.

[0092] For example, monopolar and bipolar currents simultaneously to When output is enabled, the needle electrode outputs a bipolar current, and the needle tip, which is the surface to which the needle is attached, can output a monopolar current to the skin surface.

[0093] Furthermore, the patterns output to the output setting pattern include monopolar-bipolar patterns (MB), bipolar-monopolar patterns (BM), monopolar-bipolar-monopolar patterns (MBM), bipolar-monopolar-bipolar patterns (BMB), and others.

[0094] On the other hand, the control unit 140 is monopolar and bipolar or 、 It can have the following pattern in which bipolar and monopolar outputs are output sequentially.

[0095] For example, the continuously output patterns include monopolar-monopolar patterns (MM) or bipolar-bipolar patterns (BB).

[0096] In other words, a monopolar-monopolar pattern (MM) is a pattern in which a monopolar current is output under the first condition, and then a monopolar current is continuously output under the second condition.

[0097] Furthermore, a bipolar-bipolar pattern (BB) is a pattern in which a bipolar current is output under the first condition, and then a bipolar current is continuously output under the second condition.

[0098] In the case of a monopolar-monopolar pattern (MM), a second high-frequency power supply generation unit 120 is additionally configured. 、 By preventing interference between multiple adjacent electrodes within the electrode section 300, a uniform current of the same polarity can be output to each electrode, thereby maximizing the effectiveness of the monopolar type.

[0099] Furthermore, the control unit 140 can control the electrode unit 300 to output a monopolar current based on user input, and then, after a predetermined time has elapsed, to output a bipolar current.

[0100] Figure 10 is a block diagram illustrating the case where the power supply output is bipolar in the system shown in Figure 1, and includes a high-frequency current output device 1000.

[0101] The high-frequency current output device 1000 is Skincare device Includes 100, a handpiece 200, and an electrode unit 300.

[0102] Figure 11 is a block diagram illustrating the case where the power output is monopolar in the system shown in Figure 1.

[0103] Figure 12 is a block diagram illustrating the case in the system shown in Figure 1 where the power output is monopolar and the second high-frequency power generation unit 120 is additionally driven in addition to the first high-frequency power generation unit 110.

[0104] Figure 13 is a block diagram illustrating the case where the power supply output is a continuous output of monopolar and bipolar currents in the system shown in Figure 1.

[0105] Figure 15 is a block diagram of a system including a high-frequency current output device 2000 according to another embodiment of the present invention, Skincare device It includes 100, a handpiece 200, an electrode unit 400, and a high-frequency current output device 2000.

[0106] Skincare device 100 includes a first high-frequency power generation unit 110, a second high-frequency power generation unit 120, a switching circuit 130, and a control unit 140.

[0107] In this case, the second high-frequency power generation unit 120 is the same as the high-frequency current output device 1000 according to one embodiment shown in Figure 1. to , Skincare device At 100, basically only the first high-frequency power generation unit 110 is driven, and the second high-frequency power generation unit 120 is additionally driven to prevent interference effects between one or more adjacent electrodes in the electrode unit 300.

[0108] Furthermore, the electrode section 400 comprises a plurality of first electrodes 4 10-1 to 410-N Reach and multiple second electrodes 4 20-1 to 420-N of include.

[0109] The high-frequency current output device 2000 according to another embodiment of the present invention shown in Figure 15 is identical to the high-frequency current output device 1000 according to one embodiment of the present invention shown in Figure 1, except for the electrode section 400.

[0110] That is, the first electrode 410-N and the second electrode 420-N in the electrode portion 400 of another embodiment of the present invention are film-type electrodes (FPCBs), and are electrically insulated from each other at other positions spaced apart on the FPCB.

[0111] Furthermore, each of the first electrode 410-N and the second electrode 420-N is composed of multiple units, arranged alternately in a plate shape such as a rectangle, right triangle, or isosceles triangle, so as not to overlap, and electrically interconnected.

[0112] This is because film-type electrodes are thin films, and this is to account for potential leakage currents between electrodes that may occur when the electrodes are arranged alternately.

[0113] Figure 16 is a block diagram illustrating the case where the power output mode is bipolar, as shown in Figure 15. Skincare device Includes 100, a handpiece 200, and an electrode unit 400.

[0114] When comparing the high-frequency current output device 2000 according to another embodiment of the present invention shown in Figure 16 with the high-frequency current output device 1000 according to one embodiment of the present invention shown in Figure 10, all components except the electrode section 400 are identical. Therefore, the specific operation will be described by following the operation of the high-frequency current output device 1000 according to one embodiment of the present invention shown in Figure 10, which will be described later.

[0115] Figure 17 is a block diagram illustrating the case where the power output is monopolar in the system shown in Figure 15. Skincare device Includes 100, a handpiece 200, and an electrode unit 400.

[0116] When comparing the high-frequency current output device 2000 according to another embodiment of the present invention shown in Figure 17 with the high-frequency current output device 1000 according to one embodiment of the present invention shown in Figure 11, all components except the electrode section 400 are identical. Therefore, the specific operation will be described by following the operation of the high-frequency current output device 1000 according to one embodiment of the present invention shown in Figure 11, which will be described later.

[0117] Figure 18 is a conceptual diagram illustrating a first embodiment of impedance matching operation in the system shown in Figures 1 and 15, where the power supply output pattern is mono-bi-pattern (MB).

[0118] Figure 19 is a conceptual diagram illustrating a second embodiment of impedance matching operation in the system shown in Figures 1 and 15, where the power supply output pattern is mono-bi-pattern (MB).

[0119] Figure 20 is a block diagram of a system including a high-frequency current output device 1000 according to yet another embodiment of the present invention, Skincare device Includes 100, a handpiece 200, an electrode section 300, and a counter electrode plate (NE Pad).

[0120] As can be seen from Figure 10, it is possible to continuously output monopolar and bipolar currents. Skincare device 100, the handpiece 200, and the electrode section 300 are electrically connected to each other. Skincare device 100 includes first and second high-frequency power generation units 110, 120 and a switching circuit 130.

[0121] Furthermore, when viewed from above, the electrode section 300 has the first electrode 310-N and the second electrode 320-N arranged in a zigzag pattern relative to each other. When viewed in cross-section, as can be seen from the lower right end of Figure 1, they are electrically connected to different inner layers of a PCB stack that is insulated from each other.

[0122] Thus, the first electrode 310-N and the second electrode 320-N are arranged in a zigzag pattern to supply current to the skin and are connected to different layers that are insulated from each other to supply the current.

[0123] Furthermore, the electrode section 300 can also be formed in the form of multiple electrodes on the surface of a needle tip, or it can be formed in the form of a needle type.

[0124] The control unit 140 receives positive and negative polarity currents from both the first and second high-frequency power generation units 110 and 120. but The first and second electrodes of the electrode section 300 are subjected to current output depending on the current applied and the manner of current output. 3 10-N, 320-N to Connect them electrically in various ways.

[0125] That is, the current output mode can be bipolar, monopolar, monopolar repeating pattern, monopolar and bipolar continuous pattern. depending on, First and second electrodes of electrode section 300 3 10-N, 320-N to The form of electrical connection is different.

[0126] First, as shown in Figure 10, when the current output is bipolar, the control unit 140 controls the switching circuit 130 so that the first electrode 310-N and the second electrode 320-N of the electrode unit 300 are connected with different polarities, and applies an alternating current to produce a bipolar output. can I will try to do so.

[0127] At this time, the control unit 140 provides electrical signals to RF2+, RF2- and the counter electrode plate (NE Pad). Na Connections are not considered.

[0128] Next, as shown in Figure 11, when the current output is monopolar, the control unit 140 controls the switching circuit 130 to simultaneously connect the first electrode 310-N and the second electrode 320-N of the electrode unit 300, and controls the high-frequency current (RF1-) of the first high-frequency power generation unit 110 to connect to the counter electrode plate (NE Pad) via a separate port (NE Port), thereby producing a monopolar output. can I will try to do so.

[0129] For example, when a high-frequency current flows, if the electrode of the electrode section 300 becomes positively polarized, the counter electrode plate (NE Pad) becomes negatively polarized, and if the electrode of the electrode section 300 becomes negatively polarized, the counter electrode plate (NE Pad) becomes positively polarized, allowing current to flow into the human body.

[0130] At this time, the control unit 140 provides electrical signals to RF2+ and RF2-. Na Connections are not considered.

[0131] Next, as shown in Figure 12, when the second high-frequency power generation unit 120 is additionally driven in addition to the first high-frequency power generation unit 110, and the current output pattern is a monopolar repeating pattern, the control unit 140 controls the switching circuit 130 so that one polarity is connected from the first high-frequency power generation unit 110 to the first electrode 310-N of the electrode unit 300, and so that the same polarity as the polarity connected from the second high-frequency power generation unit 120 to the first high-frequency power generation unit 110 is connected to the second electrode 320-N.

[0132] Furthermore, the high-frequency current (RF1-) of the first high-frequency power generation unit 110 is controlled to be connected to the counter electrode plate (NE Pad) via a separate port (NE Port), thereby producing a monopolar output. can I will try to do so.

[0133] Furthermore, the control unit 140 controls the switching circuit 130 so that the same polarity is connected to the second electrode 320-N of the electrode unit 300, and controls the second high-frequency power generation unit 120 to connect the high-frequency current (RF2-) to the counter electrode plate (NE Pad) via a separate port (NE Port), thereby generating a monopolar output. can I will try to do so.

[0134] At this time, the control unit 140 basically drives the first high-frequency power generation unit 110 and additionally drives the second high-frequency power generation unit 120 to generate a monopolar repeating pattern So that I'll do that.

[0135] The reason for additionally driving the second high-frequency power generation unit 120 in this manner is to prevent interference effects between multiple adjacent electrodes within the electrode unit 300, thereby ensuring that a uniform current is supplied to the multiple electrodes.

[0136] Next, as shown in Figure 13, when the current output pattern is a monopolar and a bipolar continuous pattern, the control unit 140 controls the monopolar alternating output and the bipolar type. and By mixing them, monopolar and bipolar types are produced. and It outputs continuously while rapidly switching connections.

[0137] In other words, in the case of monopolar alternating output, if both electrodes have the same polarity, the counter electrode plate (NE Pad) will have the opposite polarity. In the case of bipolar output, the counter electrode plate (NE Pad) is not electrically connected to a separate port (NE Port), and the first electrode 310-N and the second electrode 320-N of the electrode unit 300 are controlled to alternately have different polarities from each other.

[0138] As a result, the control unit 140 sequentially outputs from the first high-frequency power generation unit 110 and the second high-frequency power generation unit 120 via the switching circuit 130, enabling continuous bipolar and monopolar patterns.

[0139] In all the embodiments described in Figures 10 to 13, the handpiece 200, which is the part held by the physician, Skincare device It is positioned between 100 and the electrode unit 300, acting as an intermediate medium, and at the same time, it is moved while in contact with the subject's skin to change the target location.

[0140] Generally, collagen fiber and elastin fiber The density is higher in aged skin than in young skin. In Although lower, the application of electrical (RF) energy stimulates the formation of collagen and elastin. A great deal It will have an effect and be useful in rejuvenation treatments such as tightening and lifting.

[0141] In particular, the monopolar-bipolar pattern (MB) is superior to other patterns in collagen and elastin. fiber This significantly increases the density of It is This was discovered through the experiment.

[0142] In one embodiment of the present invention, in a monopolar-bipolar pattern (MB) where monopolar light is irradiated first and then bipolar light is irradiated consecutively, energy can be preferentially delivered to the lower dermis layer of the skin by the monopolar light.

[0143] When bipolar irradiation is performed immediately afterward, the skin's resistance is low, allowing for even denser, more widespread, and more uniform energy delivery to the skin layer that received monopolar irradiation.

[0144] That is, electrical Na Due to its properties, areas with higher temperatures have lower electrical resistance. Therefore, in a monopolar system, areas where the skin temperature rises have relatively lower resistance, allowing electricity to flow more smoothly.

[0145] Generally, in human tissue, the impedance (resistive component) decreases by 1.5% to 2% as the temperature increases, while electrical conductivity increases inversely. High frequencies selectively guide current along the path that allows for smoother current flow. explore The principle is applied.

[0146] In other words, The monopolar type, which is applied first, plays the role of raising the overall temperature of the skin area, and the bipolar type, which is applied afterward, plays the role of supplying energy locally to the skin area in the elevated temperature state, concentrating the ablation effect on the skin tissue. The principle of the advantages of the monopolar-bipolar pattern (MB) output compared to the bipolar output alone can be explained in detail as follows.

[0147] It output a monopolar type. Immediately When outputting a bipolar type, high frequency As mentioned above Due to its characteristics, the current is higher than when a bipolar type is output alone. fibrous It can flow to deeper areas through the fibrous septa.

[0148] However, the tissue surrounding the adipose tissue is All It is made of collagen fibrous Because it is a septum, a bipolar single output current is generally used. targetWhile it can be assumed that the fat layer is not affected, when the skin area is preheated with monopolar output, the current flows to the deeper lower dermis and even to the shallower subcutaneous fat layer. It started to happen This location can generate heat.

[0149] This means that when applying energy with the output of a monopolar-bipolar pattern (MB), it is possible to apply more effective energy than when using a bipolar pattern alone.

[0150] To be more specific, the upper dermis contains oxytalan fiber (oxytalan fibers) fiber Although it is widely distributed, fiber It helps to give elasticity to the skin and prevent fine wrinkles.

[0151] When vertically oriented electrical (RF) energy is transmitted through monopolar irradiation, the overall temperature of the tissue rises.

[0152] If bipolar irradiation is performed immediately afterward, the reduced resistance and increased conductivity allow the current to flow smoothly, transmitting electrical (RF) energy not only to the epidermis but also to the upper dermis.

[0153] This concentrates electrical (RF) energy on the upper dermis, which is crucial for elastin production, thereby promoting the formation of collagen and elastin. A great deal It will have an impact.

[0154] Here, the predetermined time is skin At the temperature depending on It can be decided.

[0155] That is, the control unit 140 after the electrode unit 300 outputs a monopolar current. skin The predetermined time can be determined based on the temperature change.

[0156] Specifically, monopolar current skin When applied, skin The temperature may rise.

[0157] Subsequently, if the current type of the electrode section 300 is changed from monopolar to bipolar, the time in between is skin No current is supplied to it. skin The temperature may drop.

[0158] The control unit 140 at this time skin To prevent the temperature from dropping below a specific temperature, a predetermined time is set, and within that time, a bipolar current is applied. skin It can be controlled to apply to [specific context].

[0159] If continuous irradiation of a monopolar-bipolar pattern (MB) or bipolar-monopolar pattern (BM) is not possible within a short relay time of little to no time within the thermal damage time (TDT), which is the time required to inflict thermal damage on the desired tissue without surrounding thermal damage, then the above High-frequency irradiation The desired effect is not achieved.

[0160] On the other hand, the control unit 140 can control the electrode unit 300 to output in monopolar or bipolar mode sequentially based on the user's manual operation, so that it outputs in monopolar or bipolar mode after the initial output.

[0161] In other words, the control unit 140 can either output a monopolar pattern from the electrode unit 300 and then convert it to a monopolar-bipolar pattern (MB), or output a monopolar pattern and then convert it to a monopolar-monopolar pattern (MM), or output a bipolar pattern and then convert it to a monopolar-monopolar pattern (BM), or output a bipolar pattern and then convert it to a bipolar-bipolar pattern (BB).

[0162] Actual experimental results showed that mono-bi-pattern (MB), mono-mono-pattern (MM), bi-mono-pattern (BM), and bi-bi-pattern (BB) were more effective than using only existing monopolar or bipolar types of collagen. fiber Increase and elastin fiber The increase effect is significant, As stated Among the current output options, the mono-bi-pattern (MB) in particular shows a decrease in CD80 (M1 marker), an increase in CD206 (M2 marker), and intracutaneous of Decreased TNF-α and increased IL-10, within aged skin of RAGE and NF-KB decrease, collagen increase, fibrillin (FBN) increase, collagen fiber Increase in elastin fiber It was found that the increase effect was even greater.

[0163] In particular, in the case of a bi-mono pattern (BM), where bipolar energy is applied first and then immediately followed by monopolar energy, the electrical (RF) energy is transmitted to the upper layers of the skin more smoothly than in a mono-bi-pattern (MB).

[0164] The reason for this is that the higher the temperature, the smoother the current flows. Therefore, when a bipolar application of electrical (RF) energy is transmitted shallowly in the horizontal direction, the electrical conductivity of the monopolar application that immediately follows increases, and the electrical (RF) energy is transmitted in the direction that allows the current to flow more smoothly.

[0165] This pattern is effective when targeting the upper layers of the skin to improve issues such as pigmentation, redness, and pores.

[0166] At this time, when RF is applied in mono-bi-pattern (MB) or bi-mono-pattern (BM), the impedance measured in monopolar is Mo The impedance measured in the bipolar type is: Ba Ipola type 、 Each party will be compensated (matched).

[0167] Impedance matching is the process of matching one output terminal to the input terminal. and This refers to a method of compensating for reflections caused by the impedances of two different connection points when connecting them.

[0168] In this invention, the monopolar impedance and bipolar impedance are compensated for, patient Applying high-frequency energy appropriate for each type High-frequency irradiation Make it so that the effect appears.

[0169] This can be explained in detail as follows:

[0170] Monopolar and bipolar types differ in the length over which electricity is recirculated.

[0171] Therefore, monopolar antennas have a higher impedance on average than bipolar antennas.

[0172] The impedance of a monopolar antenna is approximately 300Ω on average, while that of a bipolar antenna is approximately 100Ω on average.

[0173] A high impedance value means high resistance, requiring more energy to be supplied.

[0174] The average impedance of monopolar and bipolar types is around 200Ω. When impedance matching is performed using the average value, problems arise because monopolar types consume less energy, while bipolar types consume more energy.

[0175] However, until now, impedance matching methods have involved either measuring before a shot begins and compensating for that shot, or measuring at the point where a shot ends and compensating for the next shot.

[0176] However, when transmitting a monopolar-bipolar pattern or a bipolar-monopolar pattern in a single shot, both monopolar and bipolar types must be applied to that single shot. Therefore, the point where impedance is measured and the point where it is compensated for are different, which can lead to the intended result. High-frequency irradiation effect but The problem was that it was difficult to have high expectations.

[0177] Therefore, in one embodiment of the present invention, impedance matching is performed in the following manner.

[0178] First, the impedance of the tissue is measured after the shot, and the set power is transmitted during the period (duration) of the set value.

[0179] Furthermore, real-time in units of 1 to 2 ms. in The impedance will be measured and compensated for, and real-time impedance sensing and compensation will be performed even while RF is being applied.

[0180] Also, when measuring and compensating for impedance in a single shot (e.g., mono-bi-pattern), the monopolar impedance is measured when the monopolar shot ends. 、 After transmitting power corresponding to the measured impedance, the bipolar impedance is measured when the bipolar shot ends. 、 It transmits power corresponding to the measured impedance.

[0181] Furthermore, as shown in Figure 18, the first shot measures the impedance of the monopolar and bipolar types, and the second shot performs impedance matching of the monopolar and bipolar types.

[0182] In other words, in the case of a mono-bi-pattern (MB), after measuring the monopolar and bipolar types in the first shot, the impedance value measured in the first shot is matched in the second shot to adjust the power of the second shot.

[0183] Figure 18 illustrates the impedance matching operation in the case of a mono-bi-pattern (MB), where impedance measurement is performed after the shot. However, this is also possible in the case of a bi-mono pattern (BM).

[0184] In another embodiment of the present invention, impedance matching is performed in the following manner.

[0185] As one embodiment, impedance is measured before or after the RF output and used to compensate for and adjust the RF output conditions. For example, the RF output (primary detail shot within the output shot, for example) 、 After measuring the impedance before a monopolar shot, the impedance of the first-order detail shot can be compensated, and the RF output of a specific shot (first-order detail shot within the output shot, for example) can be adjusted. 、 The impedance is measured following the monopolar shot, and the subsequent shot (secondary detail short in the output shot, for example) is measured. 、 Adjust the output conditions for bipolar shots.

[0186] Specifically, as shown in Figure 19, when measuring and compensating for impedance before a single shot (e.g., a mono-bi-pattern), the impedance of a monopolar type is measured before a monopolar type shot. 、 After transmitting power corresponding to the measured impedance, the bipolar impedance is measured in the preceding stage of the bipolar shot. 、 It transmits power corresponding to the measured impedance.

[0187] Furthermore, in the second shot that immediately follows, monopolar and bipolar impedance matching are performed.

[0188] As another example, the control unit 140 can output current on the electrode unit 300 in a mono-by-mono pattern (MBM).

[0189] This pattern is electrical (RF) energy of The current is transmitted from deep vertical to shallow horizontal and then back to deep vertical. During this process, the current flows deeper and more abundantly beneath the skin, which can influence fat reduction and collagen production.

[0190] At this time, the initial monopolar output applied determines the epidermis and dermis. of overall Na Raise the temperature 、 Lower the skin's resistance to allow electricity to flow more easily.

[0191] The epidermis is the area of ​​the skin with the highest impedance, but by first raising the skin temperature with a monopolar output, the current flows more efficiently through the epidermis. To do so It plays a role in creating a suitable environment.

[0192] Furthermore, the second bipolar output applied causes a localized current to flow through the epidermal layer, which has reduced resistance, thereby increasing the temperature of the epidermal layer. As the temperature of the epidermal layer rises, its resistance decreases, allowing the next monopolar output to be applied in sequence. of It plays a role in helping the output energy penetrate deeper into the tissue.

[0193] Furthermore, the third applied monopolar output lowers the skin's impedance, allowing effective current to flow to deeper tissues. like The environment is prepared, and the electric current flows not only to the dermis but also to the fat layer, playing a role in assisting in fat reduction.

[0194] In other words, fat is usually connected by septums, but since septums are more electrically conductive than fat, the third monopolar type conducts current throughout the entire fat layer through the septums.

[0195] This stimulates the fat layer, which in turn activates the secretion of stem cells, potentially reducing the fat layer. However, it also plays a role in increasing skin elasticity by generating collagen and elastin in the dermis.

[0196] Therefore, this pattern is seen in patients whose skin has aged but who have a lot of fat under the skin, such as on the face. Take This can be considered a useful pattern.

[0197] As another example, the control unit 140 can output current on the electrode unit 300 in a bi-mono-bi-pattern (BMB).

[0198] This pattern allows effective electrical (RF) energy to be transmitted to the epidermis without causing cell death, affecting melanin, and experimental results showing its usefulness in improving age spots have recently been published in a relevant paper.

[0199] Therefore, this pattern is effective when you want to prevent the recurrence of blemishes because it transmits powerful electrical (RF) energy to the epidermal layer to improve blemishes and strengthen the basement membrane.

[0200] On the other hand, mono-bi-patterns and bi-mono patterns can be output continuously.

[0201] Furthermore, the control unit 140 can output a bipolar signal after one or more monopolar signals.

[0202] For example, the control unit 140 can output current on the electrode unit 300 in a mono-mono-bi pattern, outputting a monopolar output followed by a bipolar output.

[0203] Furthermore, the control unit 140 can output current on the electrode unit 300 in a mono-by-by pattern, where a bipolar output is output immediately after a monopolar output.

[0204] Furthermore, it can output a monopolar signal after one or more bipolar signals.

[0205] For example, the control unit 140 can output current on the electrode unit 300 in a bi-by-mono pattern, outputting a bipolar type output followed by a bipolar type output.

[0206] Furthermore, the control unit 140 can output current on the electrode unit 300 in a bi-mono-mono pattern, where a monopolar output is output immediately after a bipolar output.

[0207] On the other hand, the significance of this output pattern lies in the alternating use of monopolar and bipolar types, and the output form, such as the order of the types, is limited. So do not have.

[0208] The control unit 140 determines that the electrode unit 300 outputs the bipolar current based on the user's input operation, and for a predetermined time but Progress did Later, the electrode unit 300 can be controlled to output the monopolar type current.

[0209] Here, the predetermined time can be set to a time of 500ms or less.

[0210] According to another embodiment of the present invention, the control unit 140 can determine a predetermined time to be within a range of 500 ms.

[0211] On the other hand, if multiple electrodes are formed in the electrode section 300 using multiple needle-type electrodes, the first electrode 310-N and the second electrode 320-N, Ni -dollar of Insertion do In the process, bipolar current and 、 Monopolar current and, Outputting patterns that change each other High-frequency irradiation It can also be done.

[0212] On the one hand, the control unit 140 can determine the output energy of the monopolar type and the bipolar type within the range of 2 W to 400 W.

[0213] In addition, the control unit 140 can determine the output time (pulse duration) of the monopolar type and the output time of the bipolar type within the range of 10 ms to 9000 ms, and it is preferable to determine within the range of 10 ms to 990 ms.

[0214] The control unit 140 can determine the frequency of the current generated by the first high-frequency power supply generation unit 110 and the second high-frequency power supply generation unit 120 within the range of 0.3 MHz to 67.8 MHz, and it is preferable to determine within the range of 0.5 MHz to 67.8 MHz.

[0215] In addition, the control unit 140 can control a switching element 130 that can transmit two electrodes or currents of different polarities to the electrode unit 300.

[0216] Corresponding to the performance of the components of the high-frequency current output device 1000 shown in FIG. 1, at least either one component can be added or deleted.

[0217] Also, it will be easily understood by those having ordinary knowledge in the art that the mutual positions of the components can be changed corresponding to the performance or structure of the system.

[0218] On the other hand, each component shown in FIG. 1 means a component of hardware such as software and / or a Field Programmable Gate Array (FPGA) and an Application Specific Integrated Circuit (ASIC).

[0219] FIG. 3a is a vertical cross-sectional view of a plurality of electrodes according to an embodiment of the present invention, and FIG. 3b is a plan view of a plurality of electrodes according to an embodiment of the present invention.

[0220] FIG. 4a is a vertical cross-sectional view when a plurality of electrodes according to an embodiment of the present invention are provided on a non-invasive electrode, and FIG. 4b is a plan view of the plurality of electrodes in the case of FIG. 4a.

[0221] FIG. 5a is a plan view when a plurality of electrodes according to an embodiment of the present invention are provided on an invasive electrode, and FIG. 5b is a side view of the plurality of electrodes in the case of FIG. 5a.

[0222] FIG. 6 is an image showing the results of collagen generation by the output of monopolar or bipolar current of the present invention.

[0223] Referring to FIG. 6, in the case of the bi-bipolar pattern (BB) that outputs in the bipolar type after the bipolar type output, the bi-monopolar pattern (BM) that outputs in the monopolar type after the bipolar type output, the mono-monopolar pattern (MM) that outputs in the monopolar type after the monopolar type output, and the mono-bipolar pattern (MB) that outputs in the bipolar type after the monopolar type output, the results of collagen generation can be compared. Here, the area of the collagen generation result value of the bi-bipolar pattern (BB) is C1, the area of the collagen generation result value of the bi-monopolar pattern (BM) is C2, the area of the collagen generation result value of the mono-monopolar pattern (MM) is C3, and the area of the collagen generation result value of the mono-bipolar pattern (MB) can be C4.

[0224] As a result of conducting tissue experiments as shown in FIG. 6, it can be confirmed that the high-frequency output of the continuous mono-bipolar pattern (MB) of the monopolar type and the bipolar type and the continuous bi-monopolar pattern (BM) of the bipolar type and the monopolar type is most effective for collagen generation than the bipolar type or the monopolar type. Ta [[ID=1​​​​​​​

[0226] Collagen present in the skin denatures due to factors such as UV exposure, family history, and the aging process, leading to wrinkles. Therefore, various treatment methods that act only on individual skin layers have clinical limitations because they cannot cause the overall biochemical changes in collagen itself.

[0227] In practice, for clinical effectiveness across all skin layers, bipolar (or monopolar) types are used first. High-frequency irradiation Furthermore, they have changed the type and are using a monopolar (or bipolar) type.

[0228] When selecting the type, choose between monopolar and bipolar. to, Alternatively, an additional operation (task) is required to switch from bipolar to monopolar, and due to technical limitations, devices that can output monopolar and bipolar, or bipolar and monopolar, simultaneously or with a short relay time in a single operation were not supplied.

[0229] The apparatus according to the present invention enables continuous output in a single pattern (MB, BM, MBM, BMB, MMB, BBM, etc.) by combining monopolar and bipolar types or bipolar and monopolar types. High-frequency irradiation It can maximize the effect.

[0230] Furthermore, as shown by the dotted line in Figure 3b, the multiple electrodes within the electrode section 300 can be divided into a monopolar electrode group (A) and a bipolar electrode group (B), allowing for simultaneous output of monopolar and bipolar currents for each group.

[0231] In Figure 3b, for ease of understanding, we have illustrated a division into four groups, but it is also possible to further subdivide these into subgroups.

[0232] In one embodiment of the present invention, when monopolar irradiation is performed first, followed by bipolar irradiation, collagen and collagen are irradiated in both the upper and lower dermis. fiber increases such as but Confirmation can It is confirmed that this energy transmission pattern causes a total biochemical change in the collagen itself by applying a thermal effect to the entire layer of the skin. but Confirmation can has been done.

[0233] In terms of electrical characteristics, since the resistance of a high-temperature part is low, electricity flows well.

[0234] When the monopolar type is used to transmit energy to the lower dermis of the skin and then the bipolar type is immediately irradiated, due to the low resistance, the energy is transmitted more densely, widely, and uniformly to the skin layer where the monopolar type has been transmitted. This is the principle.

[0235] When the bipolar type is irradiated first and then the monopolar type is continuously irradiated, similarly, since the resistance of the part where the bipolar type is transmitted is low, electricity flows well.

After the user sets a monopolar-bipolar or bipolar-monopolar pattern via the setting window, if the pattern output key 1 is input, the control unit 140 can output various combination patterns of monopolar and bipolar types set by the user.

[0242] Figure 9 shows the range of high-frequency heat transfer when an electrode according to one embodiment of the present invention operates in a bipolar manner, in a monopolar manner, and in a monopolar-bipolar (MB) pattern.

[0243] According to one embodiment of the present invention, the high-frequency output device according to one embodiment outputs a new energy transfer pattern by changing the method of energy transfer, resulting in an immediate reaction in which the length of collagen proteins shortens due to denaturation of collagen proteins caused by heat generated by high frequency, causing skin contraction, and a delayed reaction in which damaged tissue is regenerated by high-frequency heat while new collagen synthesis increases. and, Induce 、 By transmitting energy to all layers of the skin High-frequency irradiation It will be effective.

[0244] Figure 14 shows a comparison of the expression levels of factors associated with skin aging when the electrode unit 300 operates in a mono-mono pattern (MM), mono-bi-pattern (MB), bi-mono pattern (BM), and bi-bi-pattern (BB) on young and aged skin according to one embodiment of the present invention.

[0246] As shown in Figure 14, the expression of MMP2 / MMP3 / MMP9 was significantly higher in aged skin than in young skin.

[0247] These phenomena were significantly reduced by the application of electrical (RF) energy in all four patterns, but the reduction was most pronounced in the mono-bi pattern (MB).
