Description

High frequency current output device {HIGH FREQUENCY CURRENT OUTPUT DEVICE}

The present invention relates to a high-frequency current output device.

Currently, high-frequency current output devices are used to perform high-frequency irradiation for tightening, acne, and pigmentation.

Examples of the operation of such a high-frequency current output device include an invasive device, such as a needle, in which high frequencies are transmitted by making a hole in the skin, and a non-invasive method that transmits high frequencies on the skin surface.

The most common methods of transmitting high-frequency energy are the monopolar type and the bipolar type. With a single operating device, the monopolar type or the bipolar type can be used depending on the depth of high-frequency irradiation to the skin. is used selectively.

In this way, the mechanism of high-frequency irradiation using high frequencies can be explained in two ways.

First, it causes contraction of the entire skin and subcutaneous tissue through heating of dermal collagen fibers, and second, it promotes collagen regeneration through collagen coagulation degeneration.

The bipolar type has limited heating amount and penetration depth, whereas the monopolar type can use a sufficient amount of energy at a greater depth.

The bipolar type is known to be effective in treating blemishes, capillary dilatation, enlarged pores, and mild wrinkles, while the monopolar type is known to be effective in improving wrinkles and sagging skin.

As such, the bipolar type and monopolar type are selected and used depending on the purpose of high-frequency irradiation because the depth to which high-frequency energy is transmitted is different.

However, when selecting a pattern that is a combination of these two or more types, additional operations are required to change from monopolar type to bipolar type or from bipolar type to monopolar type, and you can change between monopolar type and bipolar type or bipolar type and monopolar type with one operation. Devices that output simultaneously or with a short relay time were not supplied.

In addition, monopolar type and bipolar type can be selected and used in one high-frequency current output device, but the monopolar type has a problem in that when the same polarity is given to all needles, electrode bias occurs due to the proximity effect of the needles. .

Therefore, there is a need for devices and research that can maximize the high-frequency irradiation effect by enabling continuous output of monopolar type and bipolar type or bipolar type and monopolar type in one pattern.

Figure 1 is a block diagram of a system including a high-frequency current output device 1000 according to an embodiment of the present invention, including a skin care device 100, a handpiece 200, an electrode unit 300, and a high-frequency current output device. Includes an output device 1000.

At this time, the components of the above-mentioned high-frequency current output device 1000 are integrated into one body, or at least some components are separated from each other, but the separated components transmit and receive signals through mutual wired or wireless communication. This is possible.

The skin care device 100 includes a first high-frequency power generator 110, a second high-frequency power generator 120, a switching circuit 130, and a control unit 140.

At this time, in the skin care device 100, only the first high-frequency power generator 110 is basically driven, and the second high-frequency power generator 120 is used to prevent interference between a plurality of adjacent electrodes in the electrode portion 300. is run additionally.

Here, the second high-frequency power generator 120 is connected to an electrode separate from the first high-frequency power generator 110 and supplies current.

In addition, the electrode unit 300 includes a plurality of electrodes electrically connected to the needle tip, that is, a plurality of first electrodes 310-1 to 310-N and a plurality of second electrodes 320-1 to 320-N. Includes.

FIG. 2 is an internal block diagram of the switching circuit 130 in the skin care device 100 shown in FIG. 1 and includes a distributor 131 and a relay 132.

The control unit 140 includes an algorithm or an algorithm for controlling the operation of the first high-frequency power generator 110, the second high-frequency power generator 120, and the switching circuit 130 in the skin care device 100 of the present invention. It may be implemented with a memory that stores data for a reproduced program, and at least one processor (not shown) that performs an operation described later using the data stored in the memory.

Here, the first high-frequency power generator 110 and the second high-frequency power generator 120 are only shown as separated to show equal output between electrodes.

That is, the basic switching operation of the switching circuit 130 of the present invention is through only one of the first high-frequency power generator 110 and the second high-frequency power generator 120, so that the electrode is connected to the RF electrode during high-frequency irradiation. Switching between pole plates (NE Pad) is performed.

Specifically, when the first electrode (310-N) and the second electrode (320-N) are in the electrode unit 300, and when it is a monopolar type, the first electrode (310-N) and the second electrode (320-N) N) is connected to the same polarity (for example, (+)) and the opposite polarity (for example, (-)) is connected to the opposite electrode, and when converted to the bipolar type, the second electrode 320-N is connected to the opposite polarity. connected, and the opposite plate becomes disconnected.

In addition, as a monopolar type output is provided, even if the first electrode 310-N and the second electrode 320-N are connected to the same polarity, the first electrode 310-N and the second electrode 320-N are connected to the same polarity through the rapid on/off switching operation of the switching circuit 130. The section in which power is supplied to the first electrode (310-N) and the second electrode (320-N) is varied.

Accordingly, in the monopolar type, energy is output with a close spacing between electrodes, and the skin phenomenon in which energy is concentrated to the outside can be reduced.

In order to reduce the delay in switching from the monopolar type to the first electrode (310-N) and the second electrode (320-N) according to this operating principle, in the present invention, in addition to the first high frequency power generator 110, a second It is further provided with a high-frequency power generator 120, and when monopolar, the first electrode (310-N) and the second electrode (320-N) are connected to the high-frequency power generator, respectively, so that the delay can be reduced when outputting alternately. There will be.

At this time, the separation of the first high-frequency power generator 110 and the second high-frequency power generator 120 is performed between a plurality of adjacent electrodes in the electrode unit 300 in the case of monopolar type-monopolar type alternating output. It can be additionally applied to prevent interference effects.

Smooth alternating output between the bipolar type and monopolar type is possible by the switching circuit 130.

When the bipolar type current is output after the monopolar type current is output, the control unit 140 first controls the switching operation of the switching circuit 130 when the monopolar type current is output, to the first high frequency power generator. The electrode of the first polarity of (110) is connected to the first electrode (310-N) and the second electrode (320-N), and the first high frequency that is opposite to the first polarity of the first high frequency power generator 110 The electrode of the second polarity of the power generator 110 is connected to the counter electrode (NE Pad), so that a current flows between the first electrode (310-N) and the second electrode (320-N) and the counter electrode (NE Pad). Flow can be controlled. Afterwards, when outputting a bipolar type current, the control unit 140 controls the switching operation of the switching circuit 130 to connect the electrode of the second polarity of the first high-frequency power generator 110 to the counter electrode (NE Pad). In the connected state, it is switched to be connected to the second electrode 320-N, so that current can be controlled to flow between the first electrode 310-N and the second electrode 320-N. On the other hand, when a monopolar type current is output after a bipolar type current is output, the control unit 140 may control the above process in reverse.

The electrode unit 300 may be configured to output current directly or indirectly to the skin.

The object may refer to skin undergoing tightening, acne, or pigmentation treatment.

The electrode unit 300 consists of one or more first electrodes and one or more second electrodes.

When a current of the same polarity is applied to the first electrode 310-N and the second electrode 320-N of the electrode unit 300, a monopolar type is formed and the first electrode 310-N and the second electrode (310-N) When currents of different polarities are applied to 320-N), a bipolar type is formed.

The monopolar type may refer to a type that outputs a single polarity from an electrode.

The monopolar type may refer to an output form of a plurality of electrodes that operate to reflux high frequencies from a ground electrode in contact with the skin at a separate location when high frequencies flow from the electrodes.

The bipolar type may refer to a type that outputs different polarities from electrodes.

The bipolar type may refer to an output form of a plurality of electrodes that operates so that when high-frequency energy flows from the anode of the plurality of electrodes to the skin, it flows back to the cathode provided nearby.

The bipolar type has two electrodes attached at narrow intervals to narrow the affected area by using high high frequencies, so it can be implemented so that it is not affected by high frequencies except for the designated high frequency irradiation area.

The purpose of the present invention is to improve skin tightening by using both the monopolar type and the bipolar type, and the role each type plays in the skin tightening high-frequency irradiation process will be described later.

The electrode unit 300 may be produced with an invasive microneedle, or a plurality of non-invasive electrodes may be used.

According to one embodiment of the present invention, when the invasive electrode is formed of a plurality of microneedles, the thickness of each microneedle may be within the range of 0.15 mm to 1.0 mm, but is most preferably within the range of 0.15 mm to 0.35 mm. desirable.

At this time, the current provided from the first and second high-frequency power generators 110 and 120 is used to change the temperature of the electromagnetically energized active area depth (i.e., target area) under the skin surface through the microneedle to tissue heating. Microneedles can be manufactured in various forms, such as non-insulated needles, needles with an active area formed at the distal end, and needles containing multiple active areas at the same specific location.

In addition, even when the electrode unit 300 is composed of a plurality of non-invasive electrodes, it is used to increase the temperature of the target area to a level at which tissue heating occurs, as in the case where the electrode unit 300 is composed of a microneedle.

At this time, the size of each of the plurality of 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.

Additionally, the height of each of the plurality of electrodes may be within the range of 0 mm to 50 mm, and is preferably within the range of 0 mm to 10 mm.

Meanwhile, according to one embodiment, a film provided to cover the electrode unit 300 may be further included.

At this time, the area of the film can be created within the range of 0.25 cm2 to 25 cm2.

The control unit 140 transfers the current of the two electrodes to the electrode unit 300 based on the power generated from at least one of the first high frequency power generator 110 and the second high frequency power generator 120. A plurality of electrodes output a monopolar type current, or currents of different polarities are transmitted to the first electrode (310-N) and the second electrode (320-N) so that the plurality of electrodes output a bipolar type current. You can control it to do so.

Specifically, when the control unit 140 outputs a bipolar type current using the first high frequency power generator 110, currents of different polarities are applied to the first electrode 310-N and the second electrode 320-N. In the case of outputting, alternating current may be applied.

In this case, basically only the first high-frequency power generator 110 is driven, and the second high-frequency power generator 120 may be additionally driven to prevent interference effects between a plurality of adjacent electrodes in the electrode unit 300. .

In addition, when the control unit 140 outputs a bipolar type current using the second high frequency power generator 120, currents of different polarities are applied to the first electrode 310-N and the second electrode 320-N. In the case of output, alternating current may be applied.

In this case as well, basically only the first high frequency power generator 110 is driven, and the second high frequency power generator 120 may be additionally driven for this purpose.

Meanwhile, even when the control unit 140 outputs a monopolar type current, basically only the first high-frequency power generator 110 is driven, and the second high-frequency power generator 120 may be additionally driven for this purpose. You can.

In this case, a current of the same polarity may be output to the first electrode 310-N and the second electrode 320-N, and an alternating current may be applied.

Meanwhile, when a monopolar type is output to the electrode unit 300, a counter plate (NE Pad) connected with a polarity different from the polarity applied to the electrode unit 300 is required.

Meanwhile, when the control unit 140 outputs each type of current, the relay 132 included in the switching circuit 130 may be operated.

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

Meanwhile, the control unit 140 outputs monopolar type and bipolar type, and can select the same or different frequencies for each output.

Additionally, the control unit 140 may have the following output pattern in which monopolar type and bipolar type currents are combined and output simultaneously or sequentially in an output setting pattern.

That is, the control unit 140 controls the monopolar type current and the bipolar type current to be output simultaneously or sequentially according to an output setting pattern selected by the user or automatically set.

At this time, the monopolar type current increases the overall temperature of the current supply area, and the bipolar current is a current that locally increases the temperature of the local area as energy is supplied to the local area.

For example, when a monopolar type current and a bipolar type current are output simultaneously, the needle electrode outputs a bipolar type current, and the needle tip attachment surface, which is the surface where the needle is coupled to the needle tip, outputs a monopolar type current. It can be printed on the skin surface.

In addition, the patterns output as output setting patterns are monopolar - bipolar pattern (MB), bipolar - monopolar pattern (BM), monopolar - bipolar - monopolar pattern (MBM), and bipolar - monopolar - bipolar pattern (BMB). Includes etc.

Meanwhile, the control unit 140 may have the following pattern in which monopolar type and bipolar type or bipolar type and monopolar type are output sequentially.

For example, a pattern that is continuously output includes a monopolar-monopolar pattern (MM) or a bipolar-bipolar pattern (BB).

That is, the monopolar - monopolar pattern (MM) is a pattern in which a monopolar type current is output under a first condition, and then a monopolar type current is continuously output under a second condition.

In addition, the bipolar - bipolar pattern (BB) is a pattern in which a bipolar type current is output under a first condition, and then a bipolar type current is continuously output under a second condition.

Among them, in the case of monopolar-monopolar pattern (MM), a second high-frequency power generation unit 120 is additionally configured to prevent interference effects between a plurality of adjacent electrodes in the electrode unit 300, so that each electrode is uniformly identical. Since polarity current can be output, the effect of the monopolar type can be maximized.

In addition, the control unit 140 can control the electrode unit 300 to output a monopolar type current based on the user's input operation and, after a predetermined time, output a bipolar type current. there is.

First, as shown in FIG. 10, when the current output mode is a bipolar type, the control unit 140 causes the switching circuit 130 to switch the first electrode 310-N and the second electrode (310-N) of the electrode unit 300. 320-N) is controlled so that different polarities are connected, and alternating current is applied to enable bipolar type output.

At this time, the control unit 140 does not consider electrical connections to RF2+, RF2-, and the counter electrode (NE Pad).

Next, as shown in FIG. 11, when the current output mode is a monopolar type, the control unit 140 causes the switching circuit 130 to connect the first electrode 310-N and the second electrode unit 300. The electrodes (320-N) are controlled to be connected simultaneously, and the high frequency current (RF1-) of the first high frequency power generator 110 is controlled to be connected to the counter electrode (NE Pad) through a separate port (NE Port). Enables monopolar type output.

For example, when a high-frequency current flows, if the electrode of the electrode unit 300 becomes (+) polarized, the counter electrode (NE Pad) becomes (-) polarized, and the electrode of the electrode unit 300 becomes (-) polarized. In this case, the counter electrode (NE Pad) becomes positive polarity, allowing current to flow within the human body.

At this time, the control unit 140 does not consider electrical connections for RF2+ and RF2-.

Next, as shown in FIG. 12, when the second high-frequency power generator 120 is driven additionally to the driving of the first high-frequency power generator 110, and the current output mode is a monopolar repetitive pattern, The control unit 140 controls the switching circuit 130 to connect one polarity from the first high-frequency power generation unit 110 to the first electrode 310-N of the electrode unit 300, and connects the second electrode ( 320-N) is controlled so that the same polarity as the polarity connected from the second high-frequency power generator 120 to the first high-frequency power generator 110 is connected.

In addition, the high frequency current (RF1-) of the first high frequency power generator 110 is controlled to be connected to the counter electrode (NE Pad) through a separate port (NE Port) to enable monopolar type output.

In addition, 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 the high frequency current ( Control RF2-) to be connected to the counter electrode (NE Pad) through a separate port (NE Port) to enable monopolar type output.

At this time, the control unit 140 basically drives the first high-frequency power generator 110 and additionally drives the second high-frequency power generator 120 to enable a monopolar repeating pattern.

In this way, the reason for additionally driving the second high-frequency power generation unit 120 is to prevent interference effects between a plurality of adjacent electrodes in the electrode unit 300 and to ensure that a uniform current is supplied to the plurality of electrodes.

Next, as shown in FIG. 13, when the current output mode is a monopolar and bipolar continuous pattern, the control unit 140 mixes the monopolar crossover output and the bipolar type, thereby generating the monopolar type and the bipolar type. It outputs continuously while switching connections quickly.

That is, in the case of the monopolar type crossover output, if all electrodes have the same polarity, the counter electrode (NE Pad) has the opposite polarity, and in the case of the bipolar type, the counter electrode (NE Pad) is electrically connected to a separate port (NE Port). Instead, the first electrode 310-N and the second electrode 320-N of the electrode unit 300 are controlled to cross each other and have different polarities.

Through this, the control unit 140 sequentially performs the output of the first high-frequency power generator 110 and the second high-frequency power generator 120 through the switching circuit 130, thereby enabling continuous bipolar type and monopolar type operation. It makes patterns possible.

In all of the embodiments described in FIGS. 10 to 13, the handpiece 200, which is the part held by the doctor, is located between the skin care device 100 and the electrode unit 300 and serves as an intermediary, while simultaneously It moves while in contact with the skin and changes the target point.

In general, the density of collagen fibers and elastin fibers is lower in aged skin than in young skin, and the application of electrical (RF) energy has a significant impact on collagen and elastin formation, making it suitable for rejuvenation procedures such as tightening and lifting. It becomes useful.

In particular, the monopolar-bipolar pattern (MB) has been experimentally shown to significantly increase the density of collagen and elastin fibers compared to other patterns.

According to one embodiment of the present invention, in the case of a monopolar-bipolar pattern (MB) in which the monopolar type is irradiated first and then the bipolar type is irradiated, energy can be delivered to the lower dermis layer of the skin preferentially through the monopolar type.

If the bipolar type is irradiated immediately afterward, the energy can be delivered more densely and evenly to the skin layer to which the monopolar type was delivered due to the low resistance of the skin.

In other words, due to electrical characteristics, areas with high temperatures have low electrical resistance, so in areas where the temperature of the skin is increased in the monopolar type, resistance is relatively low and electricity can flow easily.

In general, as the temperature of human tissue increases, the impedance, which is a resistance component, decreases by 1.5% to 2%, and the electrical conductivity increases in inverse proportion, and the principle of high frequency selectively finding a path for current to flow better is that Applies.

In other words, the monopolar type, which is irradiated first, serves to increase the overall temperature of the skin area, and the bipolar type, which is irradiated later, supplies energy locally to the relevant skin area while the temperature is raised to provide ablation (ablation) to the skin tissue. It plays a role in concentrating the ablation effect. The principles of the advantages of monopolar-bipolar pattern (MB) output compared to the single output of the bipolar type are explained in detail as follows.

When outputting the bipolar type immediately after outputting the monopolar type, the current will flow deeper through the fibrous septae than when outputting the bipolar type alone due to the above characteristics of high frequencies. You can.

However, since everything around the fat tissue is a fibrous diaphragm made of collagen, it can be expected that the single output current of the bipolar type will generally not affect the fat layer, but the output of the monopolar type can preheat the skin area ( In pre-heating conditions, current may flow deeper into the lower dermis or even the shallow subcutaneous fat layer, causing heat generation at that location.

Because of this, when energy is applied through monopolar-bipolar pattern (MB) output, effective energy can be applied deeper than when outputting the bipolar type alone.

Looking more specifically, the upper dermal layer contains many elastic fibers called oxytalan fibers, which give elasticity to the skin and help prevent fine wrinkles.

When vertical electrical (RF) energy is delivered by monopolar type irradiation, the overall temperature of the tissue increases.

When bipolar type irradiation is performed immediately thereafter, electrical (RF) energy is transmitted not only to the epidermis but also to the upper dermis, where current flows easily due to lowered resistance and increased conductivity.

Through this, electrical (RF) energy is applied intensively to the upper dermal layer, which is important for elastin production, thereby greatly affecting the formation of collagen and elastin.

Here, the predetermined time may be determined according to the temperature of the skin.

That is, the control unit 140 may determine the predetermined time based on a change in skin temperature after the electrode unit 300 outputs a monopolar type current.

Specifically, when a monopolar type current is applied to the skin, the temperature of the skin may increase.

Afterwards, when the current type of the electrode unit 300 is changed from the monopolar type to the bipolar type, current is not supplied to the skin during the period, so the skin temperature may drop.

The controller 140 may determine a predetermined time so that the skin temperature does not fall below a certain temperature during this time and control the bipolar type current to be applied to the object within that time.

Monopolar-bipolar pattern (MB) or bipolar-monopolar pattern (BM) within little or very short relay time within the thermal damage time (TDT: thermal damage time), which is the time required to cause thermal damage to the desired tissue without thermal damage to the surrounding area. The above high-frequency irradiation effects can only be achieved if continuous irradiation is possible.

Meanwhile, the control unit 140 can control the electrode unit 300 to sequentially output the monopolar type or bipolar type and then output the monopolar type or bipolar type based on the user's manual operation.

That is, the control unit 140 outputs the electrode unit 300 as a monopolar type and then changes it into a monopolar-bipolar pattern (MB) as a bipolar type, or changes the electrode unit 300 into a monopolar-monopolar pattern after it is output as a monopolar type. It may be a pattern (MM), or it may be output as a bipolar type and then become a monopolar type as a bipolar - monopolar pattern (BM), or it may be output as a bipolar type and then become a bipolar type as a bipolar - bipolar pattern (BB).

As a result of actual experiments, mono-bi pattern (MB), mono-mono pattern (MM), bi-mono pattern (BM), and bi-bi pattern (BB) produce more collagen than when using only the existing monopolar type or bipolar type. The effect of increasing fibers and elastin fibers was significant, and among the above current output options, especially mono-bipattern (MB), decreased CD80 (M1 marker), increased CD206 (M2 marker), and TNF-α in the skin. and increase in IL-10, decrease in RAGE and and NF- _K B in aged skin, increase in collagen, increase in fibrillin (FBN), increase in collagen fibers, and increase in elastin fibers. I was able to.

In particular, in the case of the bi-mono pattern (BM), in which the bipolar type is applied first and then the monopolar type, electrical (RF) energy is transmitted to the upper layer of the skin better than the mono-bi pattern (MB).

The reason is that the higher the temperature, the better the current flows. Due to the application of the bipolar type, in which electrical (RF) energy is transmitted shallowly in the horizontal direction, the electrical conductivity increases due to the monopolar type applied immediately, allowing the current to flow better. This is because electrical (RF) energy is transmitted to the flowing direction.

This pattern targets the upper layer of the skin and can be said to be an effective pattern when trying to improve pigmentation, redness, and pores.

At this time, when RF is applied with a mono-bi pattern (MB) or bi-mono pattern (BM), the impedance measured in the monopolar type is compensated (matched) to the monopolar type, and the impedance measured in the bipolar type is compensated (matched) to the bipolar type. do.

Impedance matching refers to a method of compensating by reducing reflection due to the impedance of two different connection terminals when connecting an output terminal and an input terminal.

In the present invention, the impedance of the monopolar type and the impedance of the bipolar type are compensated to apply high frequency energy appropriate to each patient type, thereby producing a high frequency irradiation effect appropriate to the type.

This is explained in detail as follows.

There is a difference in the length at which electricity is circulated between the monopolar type and the bipolar type.

Therefore, the monopolar type has a higher impedance on average than the bipolar type.

The impedance of the monopolar type is 300 Ω on average, and the impedance of the bipolar type is about 100 Ω on average.

If the impedance value is high, the resistance is high, so more energy must be supplied.

The average impedance value of the monopolar type and bipolar type is about 200 Ω, and when impedance matching is performed using the average value, problems arise in impedance matching as the monopolar type consumes less energy and the bipolar type consumes a lot of energy.

However, the method of matching impedance so far has been to measure at the front end of the shot and compensate for that shot, or to measure at the end of the shot and compensate for the next shot.

However, when transmitting a monopolar-bipolar pattern or bipolar-monopolar pattern in one shot, both the monopolar type and the bipolar type must be applied in one shot, so the point of measuring impedance and the point of compensation are different. There was a problem that it may be difficult to expect the intended high-frequency irradiation effect.

Accordingly, in one embodiment of the present invention, the impedance is matched in the following manner.

First, measure the impedance of the tissue at the back of the shot and ensure that the set power is delivered during the duration of the set value.

In addition, real-time impedance is measured and compensated in 1 to 2 ms units, and impedance is detected and compensated in real time even while RF is applied.

Additionally, when measuring and compensating for impedance in one shot (e.g., mono-bi pattern), measure the monopolar type impedance at the end of the monopolar type shot, deliver power corresponding to the measured impedance, and then deliver power corresponding to the measured impedance. When the type shot ends, the bipolar type impedance is measured and power corresponding to the measured impedance is delivered.

Additionally, as shown in FIG. 18, monopolar type impedance and bipolar type impedance are measured in the first shot, and monopolar type impedance matching and bipolar type impedance matching are performed in the second shot.

That is, in the case of a mono-bi pattern (MB), after measuring the monopolar type and measuring the bipolar type in the first shot, the power of the second shot is adjusted by matching the impedance value measured in the first shot in the second shot.

FIG. 18 exemplarily illustrates an impedance matching operation in which impedance measurement is performed at the rear of a shot in the case of a mono-bi pattern (MB), but it is also possible in the case of a bi-mono pattern (BM).

In another embodiment of the present invention, impedance is matched in the following manner.

In one embodiment, the impedance is measured before or after RF output and used to compensate and adjust the RF output conditions. For example, you can measure the impedance before the RF output (the first detail shot within an output shot, e.g. a monopolar shot) and then compensate for the impedance of the first detail shot, and then measure the impedance before the RF output of a particular shot (the first detail shot within the output shot, for example, a monopolar shot). Following the second detailed shot (e.g. monopolar shot), the impedance is measured and the output conditions are adjusted for the next subsequent shot (second detailed shot within the output shot, e.g. bipolar shot).

Specifically, as shown in Figure 19, when measuring and compensating the impedance at the front end of one shot (e.g., mono-bi pattern), the monopolar type impedance is measured at the front end of the monopolar type shot. After delivering the power corresponding to the measured impedance, the bipolar type impedance is measured at the front of the bipolar type shot and the power corresponding to the measured impedance is delivered.

In addition, in the second shot that immediately follows, monopolar type impedance matching and bipolar type impedance matching are performed.

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

In this pattern, electrical (RF) energy is transmitted in the deep vertical direction → shallow horizontal direction → deep vertical direction. In this case, the current flows deeper and more under the skin, which can affect fat reduction and collagen production.

At this time, the monopolar type output applied first raises the overall temperature of the epidermis and dermis and lowers the resistance value of the skin so that electricity can flow easily.

The part of the skin with the highest impedance is the epidermis, and the monopolar type output first raises the temperature of the skin, thereby creating an environment in which current can flow more efficiently through the epidermis.

In addition, due to the second applied bipolar type output, current flows locally through the epidermal layer with low resistance, raising the temperature of the epidermal layer. As the temperature of the epidermal layer rises, the resistance decreases, so the monopolar type output to be applied next It helps the output energy penetrate deeper.

In addition, due to the third monopolar type output, the impedance of the skin is lowered, creating an environment in which effective current can flow deeper, and the current flows not only to the dermis but also to the fat layer, helping to reduce fat. do.

In other words, fat is usually connected by a septum, and since the septum has higher electrical conductivity than fat, the third monopolar type sends electric current through the septum to the entire fat layer.

Accordingly, stimulating the fat layer activates the secretion of stem cells, thereby reducing the fat layer, but also plays a role in increasing skin elasticity by producing collagen and elastin in the dermal layer.

Therefore, this pattern can be said to be a useful pattern for patients whose skin has progressed in aging but who have a lot of fat under the skin, such as on the face.

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

This pattern transmits effective electrical (RF) energy to the epidermis without causing cell death and affects melanin, so experimental results useful for improving freckles have recently been published in a certain paper.

Therefore, this pattern can be said to be an effective pattern when trying to prevent the recurrence of melasma because strong electrical (RF) energy is delivered to the epidermal layer to improve melasma and strengthen the basement membrane.

Meanwhile, mono-bi patterns and bi-mono patterns can be output continuously.

Additionally, the control unit 140 may output a bipolar type after outputting a single or multiple monopolar types.

For example, the control unit 140 may output current on the electrode unit 300 in a mono-mono-bi pattern that outputs a monopolar type, then outputs a monopolar type, and then outputs a bipolar type.

Additionally, the control unit 140 may output current on the electrode unit 300 in a mono-by-bye pattern that outputs a monopolar type and then continuously outputs a bipolar type.

Additionally, a monopolar type can be output after single or multiple bipolar types are output.

For example, the control unit 140 may output a current on the electrode unit 300 in a by-by-mono pattern that outputs a bipolar type, then outputs a bipolar type, and then outputs a monopolar type.

Additionally, the control unit 140 may output current on the electrode unit 300 in a bi-mono-mono pattern that continuously outputs a monopolar type after outputting a bipolar type.

Meanwhile, the pattern output in this way is meaningful in that it uses monopolar types and bipolar types alternately, and the output form, such as the order of the types, is not limited.

The control unit 140 can control the electrode unit 300 to output the bipolar type current based on the user's input operation and, after a predetermined time, to output the monopolar type current. there is.

Here, the predetermined time may be determined to be 500 ms or less.

According to another embodiment of the present invention, the control unit 140 may determine the predetermined time to be within the range of 500 ms.

Meanwhile, when a plurality of electrodes in the electrode unit 300 are formed in the first electrode 310-N and the second electrode 320-N in a plurality of needle types, bipolar type current and mono current are generated during the needle insertion process. High-frequency irradiation may be performed while outputting a pattern that mutually changes polar-type currents.

Meanwhile, the control unit 140 can determine the output energy of the monopolar type and bipolar type within the range of 2 watts to 400 watts.

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

The control unit 140 may determine the frequency of the current generated by the first high-frequency power generator 110 and the second high-frequency power generator 120 within the range of 0.3 MHz to 67.8 MHz, and in the range of 0.5 MHz to 67.8 MHz. It is desirable to decide within.

Additionally, the control unit 140 may control the switching element 220 that can transmit currents of two electrodes or different polarities to the electrode unit 300.

At least one component may be added or deleted in accordance with the performance of the components of the high-frequency current output device 1000 shown in FIG. 1.

Additionally, it will be easily understood by those skilled in the art that the mutual positions of the components may be changed in response to the performance or structure of the system.

Meanwhile, each component shown in FIG. 1 refers to software and/or hardware components such as Field Programmable Gate Array (FPGA) and Application Specific Integrated Circuit (ASIC).

Figure 6 is an image showing the results of collagen production according to the monopolar type or bipolar type current output of the present invention.

Referring to Figure 6, a bi-bi pattern (BB) that outputs a bipolar type after outputting a bipolar type, a bi-mono pattern (BM) that outputs a monopolar type after outputting a bipolar type, and a monopolar type after outputting a monopolar type. Collagen production results can be compared in the case of mono-mono pattern (MM) printing, monopolar type printing, and mono-bipattern (MB) printing in bipolar type. Here, the area of the collagen production result of the bi-bi pattern (BB) is C1, the area of the collagen production result of the bi-mono pattern (BM) is C2, and the area of the collagen production result of the mono-mono pattern (MM) is C2. The area of the value may be C3, and the area of the collagen production result of the mono-bi pattern (MB) may be C4.

As a result of the tissue experiment as shown in Figure 6, the continuous mono-bi pattern (MB) of the monopolar type and the bipolar type and the continuous bi-mono pattern (BM) of the bipolar type and the monopolar type were better than the bipolar type or the monopolar type. ) It can be confirmed that the high frequency output is the most effective in collagen production.

The facial skin is largely composed of three layers. The outer layer is the epidermis, and beneath the epidermis is the dermis layer, which is rich in collagen. Below the dermis, there is a complex network of collagen fibers called the subcutaneous layer (fat layer).

Collagen present in the skin is denatured due to exposure to ultraviolet rays, family history, aging process, etc., causing wrinkles to form. Therefore, various high-frequency irradiation methods that only act on each skin layer have clinical limitations because they do not cause overall biochemical changes in collagen itself.

In fact, in clinical practice, in order to achieve clinical effects on all skin layers, high-frequency irradiation is first performed with the bipolar (or monopolar) type, and then the type is changed and the monopolar (or bipolar) type is used.

When selecting a type, additional operations (operations) are required to change from monopolar type to bipolar type or from bipolar type to monopolar type, and with one operation, monopolar type and bipolar type or bipolar type and monopolar type can be switched at the same time or with a short relay time. The device that outputs was not supplied due to technical limitations.

The device according to the present invention combines monopolar type and bipolar type or bipolar type and monopolar type to enable continuous output in one pattern (MB, BM, MBM, BMB, MMB, BBM, etc.), thereby achieving high frequency irradiation effect. can be maximized.

In addition, as shown by the dotted line in FIG. 3B, the plurality of electrodes in the electrode unit 300 are divided into a monopolar type electrode group (A) and a bipolar type electrode group (B), so that the monopolar type current and the bipolar type current are generated. Current can be output simultaneously for each group.

In Figure 3b, for ease of understanding, it is illustrated that it is divided into 4 groups, but it can be further subdivided to form subgroups.

According to one embodiment of the present invention, when the monopolar type was first irradiated and then the bipolar type was irradiated, an increase in collagen and collagen fibers was confirmed in both the upper and lower dermis, and this energy transfer pattern was transmitted to all layers of the skin. It was confirmed that heat action causes overall biochemical changes in collagen itself.

Due to electrical characteristics, places with high temperatures have low electrical resistance, so electricity flows easily.

When energy is delivered to the lower dermal layer of the skin with the monopolar type and then irradiated with the bipolar type, the principle is that because the resistance is low, the energy is delivered more densely and evenly to the skin layer to which the monopolar type was delivered.

If the bipolar type is irradiated first and then the monopolar type is irradiated in succession, the area where the bipolar type is delivered has low resistance, so electricity flows easily. This means that high-frequency irradiation is performed on the epidermis and upper dermis, including spots, capillaries, and pores. The necessary energy is transmitted.

In addition, the monopolar type, which is delivered following the bipolar type, delivers high-frequency energy to the lower dermis, so it is possible to obtain a synergistic high-frequency irradiation effect due to deep heat generation.

7 and 8 are diagrams showing a user interface provided by a high-frequency current output device to control current output of a plurality of electrodes according to an embodiment of the present invention.

As shown in FIG. 7, when the pattern output key 1 in the user interface is input, the control unit 140 outputs a combination pattern of bipolar type and monopolar type, and outputs it in a specific area 2 of the user interface. Information indicating the pattern being developed can be displayed.

That is, the user may control the high-frequency current output device 1000 to output current in various combination patterns of monopolar type and bipolar type through the user interface.

In addition, the user can select various patterns according to the current output option through the user interface of the device main body, and within the pattern, set the output time of the monopolar type and/or bipolar type, and set the energy output intensity. By adjusting these settings, you can receive various high-frequency irradiation effects in various patterns.

That is, as shown in FIG. 8, when a specific area 3 in the user interface is selected, the control unit 140 displays a setting window for a monopolar-bipolar (MB) pattern or a bipolar-monopolar (BM) pattern to the user. Provided, after the pattern of monopolar-bipolar or bipolar-monopolar is set by the user through the setting window, when the pattern output key (1) is input, various combination patterns of the monopolar type and bipolar type set by the user are provided. can be output.

Figure 9 is a diagram showing the high-frequency heat transfer range when the electrode according to an embodiment of the present invention operates in a bipolar type, a monopolar type, and a monopolar-bipolar (MB) pattern.

According to one embodiment of the present invention, the high-frequency output device according to one embodiment changes the method of transmitting energy and outputs a new energy transfer pattern, so that the protein length becomes shorter due to denaturation of collagen protein due to heat generation by high frequency. The effect of high-frequency irradiation can be obtained by delivering energy to all layers of the skin by inducing an immediate response in which the skin contracts and a delayed response in which collagen synthesis increases as damaged tissues are regenerated by high-frequency heat.

Figure 14 shows that the electrode unit 300 has mono-mono pattern (MM), mono-bi pattern (MB), bi-mono pattern (BM), and bi-mono pattern (BM) for young skin and aged skin according to an embodiment of the present invention. - This is a diagram comparing the results of expression levels of factors related to skin aging when operating in a bi-pattern (BB).

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

This expression was significantly reduced by the application of electrical (RF) energy in all four patterns, with the most significant reduction in the mono-bi pattern (MB).
