Abstract
The invention discloses a high-frequency current output device capable of realizing sequential and continuous output of unipolar current and bipolar current. The device is characterized by comprising: an electrode section including one or more first electrodes and one or more second electrodes; a first high-frequency power supply generating section; a switching circuit; and a control section that controls a switching operation of the switching circuit based on the power generated from the first high-frequency power generation section to output at least one of a unipolar type current, which applies the same polarity to the first electrode and the second electrode, and a bipolar type current, which applies currents of different polarities from each other.
Description
Technical Field
The present invention relates to a high-frequency current output device, and more particularly, to a device for increasing collagen, elastin, or the like by sequentially or continuously transmitting a single-pole type and a double-pole type or a double-pole type and a single-pole type at a time when a high frequency is transmitted to the skin.
Background
Currently, high-frequency current output devices are used for various Rejuvenation (Rejuvenation) procedures such as tightening, acne, and pigmentation.
Examples of the operation of such a high-frequency current output device are invasive devices such as needles that perforate the skin to deliver high frequencies, and non-invasive methods of delivering high frequencies at the skin surface.
As a method of transmitting high frequency energy, monopolar (monopolar) type and bipolar (bipolar) type are most common, and a monopolar type or a bipolar type is selectively used according to the treatment depth of the skin using one operation device.
As described above, the therapeutic mechanism using high frequency can be described in two ways.
The first is to cause contraction of the skin and the entire subcutaneous tissue by heating the dermal collagen fibers, and the second is to promote collagen regeneration by collagen coagulation and denaturation.
Bipolar heating and penetration depth are limited, as opposed to monopolar, which can use a sufficient amount of energy more deeply.
It is known that bipolar type is mainly effective for spots, telangiectasia, pore expansion, slight wrinkles, etc., and monopolar type is effective for improving wrinkles and skin sagging.
As described above, since the depths of the bipolar type and the monopolar type for transmitting high frequency energy are different, the use is selected according to the purpose of treatment.
However, when a mode that is a combination of two or more types is selected, an additional operation of switching from the monopolar type to the bipolar type or from the bipolar type to the monopolar type is required, and there is no provision for a device that outputs the monopolar type and the bipolar type or the bipolar type and the monopolar type simultaneously by one operation or outputs the monopolar type and the bipolar type or the bipolar type and the monopolar type with a short take-over time.
In addition, although a single high-frequency current output device may be selected and used, a single-pole type and a double-pole type may be used, the single-pole type has a problem in that when all the needles are given the same polarity, an electrode aggregation phenomenon occurs due to a proximity effect of the needles.
Accordingly, there is a need for devices and studies that enable continuous output of a single-pole type and a double-pole type or a double-pole type and a single-pole type in one mode to maximize therapeutic effects.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 is a diagram showing 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 treatment device 100, a handpiece 200, an electrode section 300, and the high-frequency current output device 1000.
At this time, the above-mentioned components of the high-frequency current output device 1000 are provided in one body, or are separated from each other between at least a part of the components, and these separated components can transmit and receive signals to and from each other by wired communication or wireless communication.
The skin treatment device 100 includes a first high-frequency power supply generating section 110, a second high-frequency power supply generating section 120, a switching circuit 130, and a control section 140.
At this time, in the skin treatment device 100, basically, only the first high-frequency power supply generating section 110 is driven, and the second high-frequency power supply generating section 120 is additionally driven in order to prevent interference effects between the plurality of electrodes in the vicinity of the electrode section 300.
Here, the second high-frequency power supply generating section 120 and the first high-frequency power supply generating section 110 are connected to separate electrodes and supply current.
Further, the electrode part 300 includes a plurality of electrodes electrically connected to the needle tip, that is, includes a plurality of first electrodes 310-1 to 310-N and a plurality of second electrodes 320-1 to 320-N.
Fig. 2 is an internal block diagram of the switching circuit 130 in the skin treatment device 100 shown in fig. 1, including the dispenser 131 and the relay 132.
The control section 140 may be implemented as a memory storing data of an algorithm or a program for reproducing the algorithm for controlling the operations of the first high-frequency power supply generating section 110, the second high-frequency power supply generating section 120, and the switching circuit 130 in the skin treatment device 100 of the present invention, and at least one processor (not shown) performing operations described later using the data stored in the memory.
Here, the first high-frequency power supply generating section 110 and the second high-frequency power supply generating section 120 are shown separated only for the purpose of representing uniform output between electrodes.
That is, the basic switching operation of the switching circuit 130 of the present invention is to switch the electrode connection between the RF electrode and the counter electrode plate (NE pad) during the operation by only one of the first high-frequency power supply generating section 110 and the second high-frequency power supply generating section 120.
Specifically, when the first electrode 310-N and the second electrode 320-N are provided in the electrode portion 300, the first electrode 310-N and the second electrode 320-N are connected to the same polarity [ as an example, (+) ], and the opposite polarity [ as an example, (-) ] is connected to the counter electrode plate, and when the electrode portion is converted to the bipolar type, the second electrode 320-N is connected to the opposite polarity, and the counter electrode plate is disconnected.
Further, as the output of the unipolar type is provided, the interval of supplying power to the first and second electrodes 310-N and 320-N will be changed by the switching operation of the fast on/off of the switching circuit 130 even if the first and second electrodes 310-N and 320-N are connected with the same polarity.
Thus, in the monopolar type, energy is output at a relatively close interval between the electrodes, and the skin phenomenon in which energy is concentrated to the outside can be reduced.
According to the operation principle as described above, in order to reduce the delay of switching to the first electrode 310-N and the second electrode 320-N in the unipolar type, in the present invention, the second high-frequency power supply generating section 120 is provided in addition to the first high-frequency power supply generating section 110, and the first electrode 310-N and the second electrode 320-N are respectively connected to the high-frequency power supply generating sections in the unipolar case, so that the delay can be reduced in the alternate output.
In this case, in the case of performing the single-pole-type alternating output, the first high-frequency power supply generating section 110 and the second high-frequency power supply generating section 120 may be additionally applied to prevent interference effects between the plurality of electrodes in the vicinity of the electrode section 300.
Between the bipolar and monopolar type, a smooth alternating output may be achieved by means of the switching circuit 130.
The control section 140 may control as follows: when outputting a bipolar current after outputting a unipolar current, first, the switching operation of the switching circuit 130 is controlled to connect the first polarity electrode of the first high-frequency power supply generating unit 110 to the first electrode 310-N and the second electrode 320-N, and the second polarity electrode of the first high-frequency power supply generating unit 110 opposite to the first polarity electrode is connected to the counter electrode plate (NE pad) to cause a current to flow between the first electrode 310-N and the counter electrode plate (NE pad) and between the second electrode 320-N and the counter electrode plate (NE pad), and then, when outputting a bipolar current, the switching operation of the switching circuit 130 is controlled to switch the second polarity electrode of the first high-frequency power supply generating unit 110 from being connected to the counter electrode plate (NE pad) to be connected to the second electrode 320-N, so that a current flows between the first electrode 310-N and the second electrode 320-N, and vice versa, and when outputting a bipolar current, the bipolar current is controlled to flow in reverse directions.
The electrode unit 300 may be configured to directly or indirectly output a current to the subject.
The subject may refer to skin that performs tightening, acne, pigment treatments.
The electrode portion 300 is formed by one or more first electrodes and one or more second electrodes.
The unipolar type is formed if the same polarity current is applied to the first and second electrodes 310-N and 320-N of the electrode part 300, and the bipolar type is formed if different polarity currents are applied to the first and second electrodes 310-N and 320-N.
The unipolar type may refer to a type in which a single polarity is output from an electrode.
The unipolar type may be an output form of a plurality of electrodes operated such that the high frequency is reflowed to the ground electrode in contact with the skin at other positions when the high frequency flows out from the electrodes.
The bipolar type may refer to a type in which different polarities are output from the electrodes.
The bipolar type may be an output form of a plurality of electrodes that is operated such that high-frequency energy flows back to a negative electrode provided around a positive electrode when high-frequency energy flows into the skin from the positive electrode among the plurality of electrodes.
In the bipolar type, since two electrodes are adjacent at a narrow interval, it is possible to reduce the affected area by using a high frequency so that the portions other than the predetermined treatment portion are not affected by the high frequency.
The present invention aims to achieve an effect of improving skin tightening by using both the unipolar type and the bipolar type, and the like, and what function each type plays in the skin tightening treatment will be described later.
The electrode portion 300 may be formed as an invasive microneedle (micro) or may be implemented as a plurality of non-invasive electrodes.
According to an embodiment of the present invention, when the invasive electrode is formed using a plurality of microneedles, the thickness of each microneedle may be generated in the range of 0.15mm to 1.0mm, and most preferably in the range of 0.15mm to 0.35 mm.
At this time, the current supplied from the first high-frequency power supply generating section 110 and the second high-frequency power supply generating section 120 is used to raise the temperature of the depth of the active region (i.e., target site) that is electromagnetically energized below the skin surface by the microneedle to a level at which the tissue heats, and the microneedle may be formed in various forms such as an uninsulated needle, a needle having an active region formed at the distal end portion, a needle including a plurality of active regions at specific identical positions, and the like.
In addition, in the case where the electrode portion 300 is configured by a plurality of non-invasive electrodes, the temperature of the target site is raised to a level at which the tissue is heated, as in the case of the microneedle.
At this time, it is preferable that the size of each of the plurality of electrodes is determined to be in the range of 0.16mm to 3cm, and most preferably, is determined to be in the range of 0.16mm to 10 mm.
Further, the height of each of the plurality of electrodes may be generated in the range of 0mm to 50mm, preferably, in the range of 0mm to 10 mm.
In addition, according to an embodiment, a film provided to cover the electrode part 300 may be further included.
At this time, the area of the film may be made to be 0.25cm 2 To 25cm 2 Within a range of (2).
The control section 140 may control as follows: based on the power generated from at least one of the first high-frequency power generation unit 110 and the second high-frequency power generation unit 120, the current of two electrodes is transmitted to the electrode unit 300, so that the current of one polarity type is output to the plurality of electrodes, or the current of different polarities is transmitted to the first electrode 310-N and the second electrode 320-N, so that the current of two polarity type is output to the plurality of electrodes.
Specifically, the control unit 140 may apply an alternating current when a bipolar current is output from the first high-frequency power supply generating unit 110, i.e., when currents having different polarities are output to the first electrode 310-N and the second electrode 320-N.
In this case, basically, only the first high-frequency power supply generating section 110 is driven, and the second high-frequency power supply generating section 120 may be additionally driven in order to prevent interference effects between the plurality of electrodes in the vicinity in the electrode section 300.
In addition, the case where the control unit 140 outputs a bipolar current by the second high-frequency power supply generating unit 120 is a case where currents of different polarities are output to the first electrode 310-N and the second electrode 320-N, and an alternating current may be applied.
In this case, basically, only the first high-frequency power supply generating section 110 is driven, and the second high-frequency power supply generating section 120 may be additionally driven for the above purpose.
In addition, the control unit 140 basically drives only the first high-frequency power supply generating unit 110 when outputting a unipolar current, and may additionally drive the second high-frequency power supply generating unit 120 for the above purpose.
In this case, the same polarity current may be output at the first electrode 310-N and the second electrode 320-N, and the alternating current may be applied.
In addition, when outputting the unipolar type to the electrode portion 300, a constitution of being connected to a counter plate (NE pad) having a polarity different from the polarity applied to the electrode portion 300 is required.
In addition, the control section 140 may enable the relay 132 included in the switching circuit 130 to operate when outputting various types of currents.
In the case where the distributor 131 and the relay 132 included in the switching circuit 130 operate, an intermittent interval of at most 500ms may be generated between outputs.
The control unit 140 may output both the unipolar type and the bipolar type, and may select the same or different frequencies at the time of each output.
The control unit 140 may have a mode as described below in which the current of the unipolar type and the current of the bipolar type are outputted in combination, and the current is outputted simultaneously or sequentially in the output setting mode.
That is, the control unit 140 controls the unipolar current and the bipolar current to be simultaneously or sequentially output by the user selection or according to the automatically set output setting mode.
In this case, the unipolar current is a current that increases the temperature of the entire current supply region, and the bipolar current is a current that locally increases the temperature of the local region by supplying energy to the local region.
For example, in the case where the monopolar type current and the bipolar type current are simultaneously output, the bipolar type current may be output from the needle electrode, and the monopolar type current may be output from the needle tip attachment surface, which is the surface of the needle tip to which the needle is bonded, to the skin surface.
Further, the modes output in the output setting mode include a monopolar-bipolar mode MB, a bipolar-monopolar mode BM, a monopolar-bipolar-monopolar mode MBM, a bipolar-monopolar-bipolar mode BMB, and the like.
The control unit 140 may have the following modes of continuously outputting the single-pole type and the double-pole type or the double-pole type and the single-pole type.
For example, the modes of continuous output include a monopolar-monopolar mode MM or a bipolar-bipolar mode BB.
That is, the monopolar-monopolar mode MM is a mode in which a current of a monopolar type is output under a first condition and then a current of a monopolar type is continuously output under a second condition.
Further, the bipolar-bipolar mode BB is a mode in which a bipolar current is outputted under a first condition, and then a bipolar current is outputted continuously under a second condition.
In the case of the monopolar-monopolar mode MM, the second high-frequency power supply generating unit 120 is additionally provided to prevent interference effects between a plurality of electrodes in the electrode unit 300, and thus, the same polarity current can be uniformly output from each electrode, thereby maximizing the monopolar effect.
The control unit 140 may control the electrode unit 300 to output a unipolar current based on an input operation by a user, and the electrode unit 300 to output a bipolar current after a predetermined time has elapsed.

Fig. 15 is a block diagram of a system including a high-frequency current output device 2000 according to another embodiment of the present invention, including a skin treatment device 100, a handpiece 200, an electrode section 400, and the high-frequency current output device 2000.
The skin treatment device 100 includes a first high-frequency power supply generating section 110, a second high-frequency power supply generating section 120, a switching circuit 130, and a control section 140.
At this time, the second high-frequency power supply generating section 120 is basically driven only the first high-frequency power supply generating section 110 in the skin treatment device 100, and the second high-frequency power supply generating section 120 is additionally driven in order to prevent interference effects between one or more electrodes close to each other in the electrode section 300, as in the high-frequency current output device 1000 according to an embodiment shown in fig. 1.
Further, the electrode part 400 includes a plurality of first electrodes 410-1 to 410-N and a plurality of second electrodes 420-1 to 420-N.
The high-frequency current output apparatus 2000 according to another embodiment of the present invention shown in fig. 15 is identical to the high-frequency current output apparatus 1000 according to an embodiment of the present invention shown in fig. 1 except for the electrode part 400.
That is, the first electrode 410-N and the second electrode 420-N in the electrode part 400 of another embodiment of the present invention are electrically insulated as film type electrodes (FPCBs) at different positions spaced apart from each other on the FPCBs, respectively.
Further, each of the first electrodes 410-N and the second electrodes 420-N is constituted in plurality, alternately arranged in a plate shape having a rectangular shape, a right triangle shape, an equilateral triangle shape, or the like in a non-overlapping manner with each other, and electrically connected to each other.
This is because the film-type electrodes are thin film-type electrodes having a relatively small thickness, and thus are intended to cope with leakage currents between electrodes that may occur when the electrodes are alternately arranged.

Fig. 20 is a block diagram of a system including a high-frequency current output device 1000 according to still another embodiment of the present invention, including a skin treatment device 100, a handpiece 200, an electrode section 300, and a counter electrode plate (NE pad).
As shown in fig. 10, the skin treatment device 100, the handpiece 200, and the electrode section 300 are electrically connected to each other so as to be able to continuously output a single-pole type and a double-pole type current, and the skin treatment device 100 includes a first high-frequency power supply generating section 110 and a second high-frequency power supply generating section 120, and a switching circuit 130.
Further, when the electrode part 300 is viewed from above, the first electrode 310-N and the second electrode 320-N are arranged in a zigzag shape with each other, and when viewed in cross section, as viewed from the right lower end of fig. 1, are electrically connected to different inner layers in a Printed Circuit Board (PCB) stack that is insulated from each other.
As described above, the first electrode 310-N and the second electrode 320-N are arranged in a zigzag shape to supply current to the skin, are connected to different layers insulated from each other, and supply current.
The plurality of electrodes of the electrode portion 300 may be formed on the surface of the needle tip or may be formed in a needle shape.
The control part 140 receives the electric currents of the (+) polarity and the (-) polarity from both the first and second high-frequency power generation parts 110 and 120, and is variously electrically connected with the first and second electrodes 310-N and 320-N of the electrode part 300 according to the current output form.
That is, the current output forms are bipolar, unipolar, monopolar repetition mode, monopolar and bipolar continuous mode, respectively, and are different from the form in which the first electrode 310-N and the second electrode 320-N of the electrode portion 300 are electrically connected.
First, as shown in fig. 10, in the case where the current output form is of the bipolar type, the control section 140 controls the switching circuit 130 to connect different polarities to the first electrode 310-N and the second electrode 320-N of the electrode section 300, and applies an alternating current to enable bipolar output.
At this time, the control unit 140 does not consider the electrical connection to the electrode plate (NE pad) of RF2+, RF 2-.
Then, as shown in fig. 11, in the case where the current output form is of the unipolar type, the control section 140 controls the switching circuit 130 to connect the first electrode 310-N and the second electrode 320-N of the electrode section 300 simultaneously, and controls the high-frequency current RF 1-of the first high-frequency power supply generating section 110 to be connected to the counter plate (NE pad) through a separate port (NE port) to enable the unipolar type output.
For example, when a high-frequency current flows, the counter plate (NE pad) is in the (-) polarity when the electrode of the electrode portion 300 is in the (+) polarity, and the counter plate (NE pad) is in the (+) polarity when the electrode of the electrode portion 300 is in the (-) polarity, so that the current flows in the human body.
At this time, the control unit 140 does not consider the electrical connection between the RF2+ and RF 2-.
Then, as shown in fig. 12, in the case where the second high-frequency power supply generating section 120 is additionally driven on the basis of the driving of the first high-frequency power supply generating section 110, in the case where the current output form is the single-pole repetition mode, the control section 140 controls the switching circuit 130 to connect one polarity of the first high-frequency power supply generating section 110 to the first electrode 310-N of the electrode section 300 and to connect the same polarity of the second high-frequency power supply generating section 120 as the polarity connected to the first high-frequency power supply generating section 110 to the second electrode 320-N.
Further, the high-frequency current RF 1-of the first high-frequency power supply generating section 110 is controlled to be connected to the counter plate (NE pad) through a separate port (NE port) to enable monopolar output.
Further, the control section 140 controls the switching circuit 130 to connect the same polarity to the second electrode 320-N of the electrode section 300 and controls the high-frequency current RF2 of the second high-frequency power supply generating section 120 to be connected to the counter plate (NE pad) through a separate port (NE port) to enable monopolar output.
At this time, the control unit 140 basically drives only the first high-frequency power supply generating unit 110, and additionally drives the second high-frequency power supply generating unit 120 to enable the monopole repetition mode.
As described above, the second high-frequency power supply generating section 120 is additionally driven to supply a uniform current to the plurality of electrodes in order to prevent interference effects between the plurality of electrodes in the vicinity of the electrode section 300.
Then, as shown in fig. 13, in the case where the current output form is the monopolar and bipolar continuous mode, the control section 140 rapidly switches the connection of the monopolar type and the bipolar type and continuously outputs by mixing the case of the monopolar alternating output and the case of the bipolar type.
Namely, the control is as follows: in the case of the monopolar type alternate output, if the electrodes are all of the same polarity, the counter plate (NE Pad) has opposite polarity, and in the case of the bipolar type, the counter 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 part 300 alternately have polarities different from each other.
Thus, the control unit 140 sequentially executes the outputs of the first high-frequency power supply generating unit 110 and the second high-frequency power supply generating unit 120 by the switching circuit 130, thereby realizing the bipolar type and the unipolar type continuous modes.
In all of the embodiments illustrated in fig. 10 to 13, the handpiece 200, which is a portion held by a doctor, is located between the skin treatment device 100 and the electrode section 300 to function as an intermediate medium while moving and changing the target point in a state of being in contact with the skin of the subject.
Generally, collagen fibers and elastin fibers of aged skin have a lower density than young skin, and the application of electrical (RF) energy will have a great impact on collagen and elastin formation, and thus are useful for rejuvenation such as tightening and pulling.
In particular, experiments have shown that monopolar-bipolar mode MB significantly increases the density of collagen and elastin fibers compared to other modes.
In accordance with an embodiment of the present invention, in the case of the monopolar-bipolar mode MB of the bipolar type being irradiated first and then continuously, energy may be transferred to the lower dermis layer of the skin preferentially in the monopolar type.
Then, in the case of the bipolar type irradiation, since the electric resistance of the skin is low, the energy can be more densely and more widely, uniformly, and better transferred to the skin layer to which the unipolar type is transferred.
That is, because of the electrical characteristics, the resistance at the position where the temperature is high is low, and therefore the resistance at the position where the temperature of the skin is raised by the monopole is relatively low, so that the electric current can be supplied better.
In general, the principle of application to human tissue is that as the temperature increases, the impedance as a resistive component decreases by 1.5% to 2%, while the conductivity increases inversely proportional, and a path (path) where the current flows better is selectively found at high frequencies.
In other words, the monopolar type of irradiation first serves to raise the overall temperature of the skin region, and the bipolar type of irradiation later serves to locally supply energy to the corresponding skin region in a state of temperature rise and concentrate the ablation (ablation) effect to the skin tissue. The principle of the advantages that the monopolar-bipolar mode MB output has over the bipolar-only output is described in detail below.
In the case of outputting the bipolar type immediately after outputting the unipolar type, due to the above-described characteristics of the high frequency, the current can flow further through the fibrous septums (fibrous septaes) to a deeper depth than the bipolar type alone.
However, since the periphery of adipose tissue is a fibrous membrane composed of collagen, it is expected that bipolar type output current alone does not generally affect the fat layer, whereas in a state where the skin region is preheated (pre-heating) by the unipolar type output, the current flows to the lower dermis (lower dermis) which is more deep, even the superficial subcutaneous fat layer, and causes heat generation at this location.
Thus, when energy is applied in the monopolar-bipolar mode MB, effective energy can be applied more deeply than when bipolar type is output alone.
More specifically, there are a number of spandex fibers distributed in the upper dermis, known as acid hydrolysis resistant fibers (oxyalan fibers), which help impart elasticity to the skin and prevent fine wrinkles.
If the vertical form of electrical (RF) energy is delivered by a monopolar type of irradiation, the temperature of the tissue will rise overall.
In the case where bipolar irradiation is performed immediately thereafter, electric (RF) energy is transferred not only to the epidermis but also to the upper dermis at a position where current flows well due to reduced electrical resistance and increased electrical conductivity.
Thus, by intensively applying electrical (RF) energy to the upper dermis layer important for elastin production, collagen and elastin formation are greatly affected.
The pre-determined time may be determined from the temperature of the subject.
That is, the control unit 140 may determine the predetermined time based on the temperature change of the object after the electrode unit 300 outputs the unipolar current.
Specifically, if a unipolar type current is applied to the object, the temperature of the object may increase.
Then, in the case where the current type of the electrode portion 300 is changed from the unipolar type to the bipolar type, since no current is supplied to the subject during the time in which the type change is performed, the temperature of the subject may be lowered.
The control part 140 may determine a predetermined time and control the bipolar type current to be applied to the object during the time to prevent the temperature of the object from falling below a specific temperature during the time.
The above clinical operation effect can be obtained only when continuous irradiation of the monopolar-bipolar mode MB or the bipolar-monopolar mode BM is achieved with little or very short take-over time within the thermal injury time (TDT: thermal damage time) which is the time required to thermally damage the desired tissue without thermal injury to the periphery. The control unit 140 may control the electrode unit 300 to sequentially output in a monopolar type or a bipolar type based on a manual operation by a user, and then output in a monopolar type or a bipolar type.
That is, the control section 140 may switch the electrode section 300 to the following mode: a monopolar-bipolar mode MB of outputting in monopolar mode and then outputting in bipolar mode; or a monopolar-monopolar mode MM in which the output is monopolar and then the output is monopolar; or a bipolar-monopolar mode BM which outputs bipolar and then monopolar; or a bipolar-bipolar mode BB in which the output is bipolar and then the output is bipolar.
From the results of the experiments actually conducted, it was found that the increase in collagen fibers and the increase in elastin fibers was greater in the single-dual mode MB, single-single mode MM, dual-single mode BM, and dual-dual mode BB than in the case of the conventional single-pole type or bipolar type alone, and that the increase in collagen fibers, the increase in elastin fibers, and the increase in collagen fibers, was greater in the current output options above, especially the decrease in CD80 (labeled M1) for single-dual mode MB, the increase in CD206 (labeled M2), the decrease in TNF- α and the increase in IL-10 in skin, the decrease in RAGE and NF-KB in aged skin, the increase in collagen, the increase in Fibrillin (FBN), the increase in elastin fibers.
In particular, in the case of applying the bipolar type immediately after applying the mono-polar type dual-mono-mode BM, electric (RF) energy is transferred to the upper layer of the skin better than the mono-dual mode MB.
This is because the higher the temperature, the better the current flows, and thus, since a bipolar type is applied that makes the electric (RF) energy transferred shallowly in the horizontal direction, the conductivity is increased by a monopolar type applied next, so that the electric (RF) energy is transferred to a position where the current flows better.
This mode is said to be effective when the upper layer of the skin is targeted to improve pigments, flushes, pores, and the like.
At this time, when RF is applied in the single-dual mode MB or the dual-single mode BM, the impedance measured at the monopole type is compensated (matched) to the monopole type, and the impedance measured at the dipole type is compensated (matched) to the dipole type.
The impedance matching (impedance matching) is a method of compensating for the difference between the impedance of two connection terminals, which are different from each other, by reducing reflection when connecting the output terminal to the input terminal.
In the present invention, a suitable type of high-frequency energy is applied to each operated person by compensating for a single-pole type impedance and a double-pole type impedance, thereby exhibiting an operation effect suitable for the respective type.
This will be described in detail below.
The unipolar and bipolar types differ in the length of the electrical return.
Therefore, the average impedance of the unipolar type is higher than that of the bipolar type.
The impedance of the unipolar type is 300 Ω on average, and the impedance of the bipolar type is about 100 Ω on average.
The higher the impedance value, the higher the resistance and therefore more energy needs to be supplied.
When impedance matching is performed on an average value, the impedance average value of the unipolar type and the bipolar type is about 200Ω, and the impedance matching causes a problem that the amount of energy consumed by the unipolar type is small and the amount of energy consumed by the bipolar type is large.
However, in the impedance matching method so far, the front end at which the transmission (shot) starts is measured and the corresponding transmission is compensated, or the point at which the transmission ends is measured and the next transmission is compensated.
However, in the case of transmitting the monopolar-bipolar mode or the bipolar-monopolar mode in one transmission, both of the monopolar type and the bipolar type need to be applied to one transmission, and therefore, there is a problem that it is difficult to expect an intended surgical effect due to a difference between a point of measuring impedance and a point of compensation.
Thus, in one embodiment of the present invention, the impedance is matched using the method described below.
First, the impedance of the tissue is measured at the back end of the emission and the set power is delivered for a set period (duration).
Further, the impedance is measured and compensated in real time in units of 1ms to 2ms, and even during the application of RF, the impedance is detected and compensated in real time.
Further, in the case where the impedance is measured and compensated in one transmission (for example, a single-double mode), the single-pole type impedance is measured and power corresponding to the measured impedance is transferred at the end of the single-pole type transmission, and then the double-pole type impedance is measured and power corresponding to the measured impedance is transferred at the end of the double-pole type transmission.
Further, as shown in fig. 18, in the first emission, the unipolar type impedance and the bipolar type impedance are measured, and in the second emission, the unipolar type impedance matching and the bipolar type impedance matching are performed.
That is, in the case of the single-dual mode MB, after the unipolar type measurement and the bipolar type measurement are performed in the first transmission, the impedance value measured at the time of the first transmission is matched in the second transmission to adjust the power of the second transmission.
The operation of impedance matching performed at the back end of the transmission for impedance measurement in the case of single-dual mode MB is exemplarily shown in fig. 18, but may also be the case of dual-single mode BM.
In another embodiment of the present invention, the impedance is matched using the method described below.
As an example, the impedance is measured before or after RF output to use the measured impedance to compensate and adjust RF output conditions. For example, the impedance is measured before RF output (one of the output transmissions, e.g., a monopole transmission), and then the impedance of the one particular transmission can be compensated, after RF output of the particular transmission (one of the output transmissions, e.g., a monopole transmission), the impedance is measured and the output conditions for the next transmission (a second particular transmission of the output transmissions, e.g., a dipole transmission) are adjusted.
Specifically, as shown in fig. 19, in the case where the front end of one transmission (for example, single-dual mode) measures and compensates for the impedance, the single-pole type impedance is measured at the front end of the single-pole type transmission and power corresponding to the measured impedance is transferred, and then the double-pole type impedance is measured at the front end of the double-pole type transmission and power corresponding to the measured impedance is transferred.
In addition, in the next second emission, a unipolar resist matching and a bipolar resist matching are performed.
As another example, the control part 140 may output a current on the electrode part 300 in a single-double-single mode MBM.
This mode transfers electrical (RF) energy in the deep vertical direction to the shallow horizontal direction to the deep vertical direction, at which point the current will flow deeper and more under the skin, which can have an impact on fat loss and collagen production.
At this time, due to the monopolar output applied for the first time, the overall temperature of epidermis and dermis is raised to lower the resistance value of the skin, so that better energization is possible.
The location of highest impedance in the skin is the epidermis, which is first raised in temperature by the unipolar output, thus serving to create an environment for more efficient current flow at the epidermis.
In addition, since the bipolar output applied for the second time causes a current to locally flow in the skin layer having a reduced resistance to raise the temperature of the skin layer, if the temperature of the skin layer is raised, the resistance is lowered, and thus functions to assist the penetration of the energy of the monopolar output applied for the next time to a deeper depth.
In addition, since the third application of the monopolar type output reduces the impedance of the skin to create an environment in which an effective current can flow deeper, the current flows not only to the dermis but also to the fat layer, thereby contributing to the reduction of fat.
That is, the fat is typically connected by a membrane (septum), which has a higher conductivity than fat, so that the third unipolar type causes current to flow through the membrane to the entire fat layer.
Thus, if the fat layer is stimulated, the secretion of stem cells (stem cells) becomes active to decrease the fat layer, but collagen and elastin of the dermis layer are also produced, and function to increase the elasticity of the skin.
Therefore, this mode is said to be a mode useful for patients having a high fat under the skin such as the face, while aging of the skin progresses.
As yet another example, the control part 140 may output a current on the electrode part 300 in a double-single-double mode BMB.
This mode does not cause cell death in the epidermis and transmits efficient electrical (RF) energy, affecting melanin, and thus, experimental results useful for improving plaque have been recently published in some paper.
Therefore, this mode is effective in preventing recurrence of spots by transmitting strong electric (RF) energy to the epidermis layer to improve spots and making the basal lamina (basement membrane) firm.
In addition, the single-double mode and the double-single mode may be continuously output.
Further, the control section 140 may output the bipolar type after outputting the single or multiple single-pole type.
For example, the control part 140 may output a current on the electrode part 300 in a single-double mode in which a single-pole type is output followed by a single-pole type.
Further, the control unit 140 may output a current to the electrode unit 300 in a single-double mode in which a single-polarity type is output and then a double-polarity type is continuously output.
In addition, the unipolar type may be output after the single or multiple bipolar types are output.
For example, the control part 140 may output a current on the electrode part 300 in a double-single mode in which a bipolar type is output followed by a bipolar type.
Further, the control unit 140 may output a current to the electrode unit 300 in a bipolar-type and then a single-type double-single-mode.
The pattern thus output is significant in terms of alternating unipolar and bipolar types, and the output form such as the order of the types is not limited.
The control unit 140 may control the electrode unit 300 to output the bipolar current based on an input operation of a user, and may cause the electrode unit 300 to output the unipolar current after a predetermined time has elapsed.
Here, the predetermined time may be determined to be 500ms or less.
According to another embodiment of the present invention, the control part 140 may determine the predetermined time to be a time within a range of 500 ms.
In addition, in the case where 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 shapes, a mode in which a bipolar current and a monopolar current are changed to each other during insertion of the needle into the treatment site of the subject may be outputted to perform the treatment operation.
In addition, the control section 140 may determine the output energy of the unipolar type and the bipolar type to be in the range of 2 watts to 400 watts.
Further, the control unit 140 may determine the output time (pulse duration) of the single-pole type and the output time of the double-pole type to be in the range of 10ms to 9000ms, preferably in the range of 10ms to 990 ms.
The control part 140 may determine the frequency of the current generated by the first high-frequency power generation part 110 and the second high-frequency power generation part 120 in the range of 0.3MHz to 67.8MHz, preferably in the range of 0.5MHz to 67.8 MHz.
Further, the control section 140 may control the switching element 220 capable of transmitting two electrodes or currents of different polarities to the electrode section 300.
At least one component may be added or deleted in accordance with the performance of the component of the high-frequency current output device 1000 shown in fig. 1.
Furthermore, one of ordinary skill in the art will readily appreciate that the mutual positions of the constituent elements may vary corresponding to the performance or structure of the system.
In addition, each of the constituent elements shown in fig. 1 refers to software and/or hardware constituent elements such as a field programmable gate array (FPGA: field Programmable Gate Array) and an application specific integrated circuit (ASIC: application Specific Integrated Circuit).

Fig. 6 is an image showing collagen production results of a unipolar or bipolar type current output according to the present invention.
Referring to fig. 6, the collagen production results in the following cases can be compared: a dual-dual mode BB output in bipolar mode and then output in bipolar mode; a dual-single mode BM output in a bipolar type and then in a monopolar type; single-single mode MM outputting in a monopolar type and then outputting in a monopolar type; single-dual mode MB output in unipolar mode followed by output in bipolar mode. Here, the area of the collagen production result value of the dual-dual mode BB may be C1, the area of the collagen production result value of the dual-single mode BM may be C2, the area of the collagen production result value of the single-single mode MM may be C3, and the area of the collagen production result value of the single-dual mode MB may be C4.
As a result of the tissue experiment shown in fig. 6, it was confirmed that the high frequency output of the single-double mode MB, which is continuous in the single-pole type and the double-pole type, and the double-single mode BM, which is continuous in the double-pole type and the single-pole type, was most effective for collagen production, compared to the bipolar type or the single-pole type.
The facial skin is mainly composed of three layers. The outer layer is the epidermis, beneath which there is a collagen-rich dermis (dermis) layer, beneath which there is a complex network of collagen fibers called the subcutaneous layer (subcutaneous layer, fat layer).
Collagen present in the skin is denatured by exposure to ultraviolet light, family history, aging process, etc., and wrinkles are generated. Thus, various treatments that act only on individual skin layers do not cause an overall biochemical change in collagen itself and are clinically limited.
In practice, clinically, for the clinical effect of all the skin layers, a bipolar (or monopolar) type treatment is used first, and then a monopolar (or bipolar) type is used, changing the type.
When the type is selected, an additional operation (work) to change from the monopolar type to the bipolar type or from the bipolar type to the monopolar type is required, and it is impossible to provide a device capable of outputting the monopolar type and the bipolar type or the bipolar type and the monopolar type simultaneously or with a short take-over time by one operation due to technical limitations.
The device according to the present invention can achieve continuous output in one mode (MB, BM, MBM, BMB, MMB, BBM, etc.) by combining the single-pole type and the double-pole type or the double-pole type and the single-pole type, thereby maximizing the therapeutic effect.
As indicated by the broken line in fig. 3B, the plurality of electrodes in the electrode section 300 are divided into a monopolar electrode group a and a bipolar electrode group B, so that a monopolar current and a bipolar current can be simultaneously output to the respective groups.
In fig. 3b, for ease of understanding, a case of dividing into four groups is illustrated, but it may be subdivided to form subgroups.
According to an embodiment of the present invention, in the case of irradiating the unipolar type first and continuously irradiating the bipolar type, an increase in collagen, collagen fibers, etc. is confirmed in both the upper dermis and the lower dermis, and it is confirmed that this energy transfer mode heat acts on all skin layers to cause an overall biochemical change in collagen itself.
Because of the electrical characteristics, the electrical resistance of the high temperature location is low, and therefore better power is supplied.
The principle is that, in the case where the bipolar type is irradiated immediately after the energy is transferred to the lower dermis layer of the skin by the monopolar type, the energy can be transferred more widely, uniformly, and better to the skin layer to which the monopolar type is transferred, with higher density, due to low impedance.
In the case of irradiating the bipolar type first and continuously irradiating the bipolar type, similarly, the electric resistance of the portion to which the bipolar type is transferred is low, so that the electric current is better supplied, and the energy necessary for the treatment is transferred to the epidermis and the upper dermis such as the spots, capillaries, pores, and the like.
Furthermore, the continuous unipolar type transmits high-frequency energy to the lower dermis after bipolar type transmission, so that a synergistic therapeutic effect due to the generation of deep heat can be obtained.
Fig. 7 and 8 are diagrams showing a user interface provided by a high-frequency current output device in order to control current output of a plurality of electrodes according to an embodiment of the present invention.
As shown in fig. 7, when an input of the mode output key 1 in the user interface is received, the control unit 140 may output in a combined mode of the bipolar type and the unipolar type, and display information indicating the mode being output in the specific area 2 of the user interface.
That is, the user can control the high-frequency current output device 1000 to output current in various combinations of the unipolar type and the bipolar type modes through the user interface.
In addition, the user can select various modes according to the current output options of the output current through the user interface of the device main body, and can set the output time of the unipolar type and/or the bipolar type, the setting of the energy output intensity, and the like in the corresponding modes, so that various therapeutic effects can be provided in various modes through these settings and adjustments.
That is, as shown in fig. 8, when the specific area 3 in the user interface is selected, the control unit 140 may provide the user with a setting window of the monopolar-bipolar MB mode or the bipolar-monopolar BM mode, set the monopolar-bipolar mode or the bipolar-monopolar mode by the user through the setting window, and then output various combinations of the monopolar mode and the bipolar mode set by the user when receiving the input of the mode output key 1.
Fig. 9 is a diagram showing high-frequency heat transfer ranges in the case where an electrode according to an embodiment of the present invention operates in a bipolar type, in the case where it operates in a monopolar type, and in the case where it operates in a monopolar-bipolar MB mode.
According to an embodiment of the present invention, the high frequency output device according to an embodiment can output a new energy transmission mode by changing the manner of transmitting energy, thereby inducing an immediate response to skin contraction due to a shortened protein length caused by denaturation of collagen protein due to heat generated by high frequency, and transmitting energy to all skin layers with a delayed response to increase new synthesis of collagen due to regeneration of tissue damaged by high frequency heat, thereby obtaining a surgical effect.
Fig. 14 is a graph showing a result of comparing the appearance level of the skin aging-related factor in the case where the electrode section is operated in the single-single mode MM, the single-double mode MB, the double-single mode BM, and the double-double mode BB for young skin and aged skin according to an embodiment of the present invention.
The figure shows the results of confirming the levels of MMP and beta-actin (beta-actin) as skin aging-related factors by immunoblotting (Western blot) as a method for detecting specific proteins by utilizing specific interactions between proteins.
As shown in fig. 14, the appearance of MMP2/MMP3/MMP9 was significantly higher in aged skin than in young skin.
This occurrence is greatly reduced by the application of electrical (RF) energy in all four modes, especially in the single-dual mode MB.
