피부의 표적 부위가 상기 진공캡의 공동부 쪽으로 흡착될 수 있도록 상기 진공캡에 기준음압을 제공하는 진공장치와,a vacuum device for providing a reference sound pressure to the vacuum cap so that the target area of the skin can be adsorbed toward the cavity of the vacuum cap;
상기 진공캡의 공동부가 음압을 유지하는 조건에서 상기 기준음압을 압력가변 밸브에 의해 1초당 0.5~50회 주기의 펄스 형태로 가변시킬 수 있도록 하고, 상기 진공캡과 피부와의 접촉부 사이에 밀착 불량이 발생하여 상기 공동부 내의 기준음압이 설정된 범위를 벗어나면 상기 진공장치가 자동으로 가동되어 상기 기준음압이 유지되도록 하는 기준음압 가변장치와,Under the condition that the cavity of the vacuum cap maintains the negative pressure, the reference sound pressure can be varied in the form of a pulse with a cycle of 0.5 to 50 times per second by a pressure variable valve, and the adhesion between the vacuum cap and the skin-contacting part is poor. When this occurs and the reference sound pressure in the cavity is out of a set range, the vacuum device is automatically operated to maintain the reference sound pressure;
상기 피부의 표적 부위가 상기 진공캡의 공동부 쪽으로 흡착되었을 때 그 흡착된 피부가 상기 진공캡의 공동부 내에서 접촉되도록 상기 진공캡의 내측 벽에 노출되어 구성되는 RF전극과,an RF electrode configured to be exposed to the inner wall of the vacuum cap so that the adsorbed skin is contacted within the cavity of the vacuum cap when the target portion of the skin is adsorbed toward the cavity of the vacuum cap;
상기 진공장치, 상기 기준음압 가변장치, 상기RF전극의 구동을 제어하는 컨트롤러를 포함하고,A controller for controlling driving of the vacuum device, the reference sound pressure variable device, and the RF electrode,
상기 기준음압 가변장치와, 상기 피부의 표적 부위를 치료하는 RF전극의 구동은 단독 구동, 동시 구동, 교대구동 중 어느 하나의 구동을 선택하여 이루어지도록 제어되되, 상기 제1 몸체부와 상기 진공캡의 탈부착은 상기 제1 몸체부의 단부에 구성되는 진공튜브 결속구와, 전원공급용 커넥터와, 클립으로 이루어진 진공캡 접속유닛의 동시 결합 및 동시 분리에 의해 이루어지는 것을 특징으로하는 진공캡의 탈부착 및 각도 조절이 가능한 핸드피스가 기재되어 있다.The driving of the reference sound pressure variable device and the RF electrode for treating the target part of the skin is controlled to be made by selecting any one of single driving, simultaneous driving, and alternating driving, the first body part and the vacuum cap attachment and detachment of the vacuum cap, characterized in that it is made by simultaneous coupling and simultaneous separation of a vacuum cap connection unit composed of a vacuum tube binding hole, a power supply connector, and a clip formed at the end of the first body part A possible handpiece is described.
상기와 같이 구성되는 핸드피스의 RF전극은 + 극성과 - 극성을 갖는 한쌍의 전극으로 이루어지고 + 극성에서 - 극성 쪽으로 고주파가 흡착된 지방층을 통과하여 흐르는 과정에서 고주파가 지방층을 파괴하여 비만등을 치료하는 메커니즘으로 되어있다. The RF electrode of the handpiece configured as described above consists of a pair of electrodes having a + polarity and a - polarity, and in the process of flowing through the adsorbed fat layer from the + polarity to the - polarity, the high frequency waves destroy the fat layer to reduce obesity, etc. mechanism of treatment.
그러나, 고주파가 + 극성에서 - 극성 쪽으로 흐르기 때문에 + 극성과 접촉된 피부 쪽에서 지방 분해 효율 또는 병변의 치료 효율이 더 높고 - 극성과 접촉된 피부 쪽에서는 상대적으로 지방분해 및 병변의 치료효율이 떨어지는 단점이 있다. However, since the high frequency flows from the + polarity to the - polarity, the lipolysis efficiency or the treatment efficiency of the lesion is higher on the skin side in contact with the + polarity, and the lipolysis and treatment efficiency of the lesion is relatively low on the skin side in contact with the - polarity There is this.
이와 같은 원인은 피부 지방층에 RF고주파가 인가될 때 그 피부 지방층이 저항체로 작용하여 - 극성 쪽으로 갈수록 고주파의 밀집도가 떨어져 지방층의 분해효율이 점점 감소하기 때문인 것으로 추정된다.It is presumed that the cause of this is that when RF high frequency is applied to the skin fat layer, the skin fat layer acts as a resistor - the density of the high frequency decreases toward the polarity, and the decomposition efficiency of the fat layer gradually decreases.
상기와 같은 단점 때문에 고주파 조사 시간을 길게하거나 고주파의 출력을 조정하는 방법이 있으나, 이 경우 피시술자의 피부에 통증을 유발할 수 있고, 시술 피부의 발열로 인한 빠른 온도 상승으로 냉각 과정이 필요하여 시술 시간이 지연되는 단점이 있다. Due to the above disadvantages, there is a method of lengthening the radio frequency irradiation time or adjusting the output of the radio frequency, but in this case, it may cause pain to the skin of the subject, and a cooling process is required due to the rapid temperature rise due to the heat of the treated skin. There is a downside to this delay.
또, 피부가 흡착된 상태에서는 RF전극의 물리적인 위치 및 방향을 쉽게 바꿀수 없어 피부 흡착부의 지방분해 효율의 균형을 맞추는데는 한계가 있다.In addition, in the state where the skin is adsorbed, the physical position and direction of the RF electrode cannot be easily changed, so there is a limit in balancing the lipolysis efficiency of the skin adsorption part.

In addition, various cooling devices (not shown) for cooling the skin in contact with the RF electrode, the vacuum cap 310 or the cavity 315 of the vacuum cap according to the temperature sensing signal of the temperature sensor 331 may be additionally installed. can
상기 한쌍의 RF전극(320a,320b)은 진공캡(310)의 마주보는 양측 내벽에 각각 양(+),음(-) 전극으로 장착되며, 고주파 발생부(미도시)로부터의 RF 고주파를 발생시켜 진공캡의 공동부 내측으로 흡인된 피부의 표적 부위에 RF 고주파를 인가할 경우 지방 조직을 구성하는 세포 분자들의 이온들은 RF전극의 교류 전류에 의하여 양(+) 전하는 음극으로 음(-) 전하는 양극으로 끌려가 분극 현상(polarization phenomenon)이 발생하게 된다. 상기 분극 작용으로 지방 세포 조직 내에 줄(Joul) 열이 집중적으로 발생하게 되면 지방 세포가 분해되므로 비만 등의 치료로 이어진다.The pair of RF electrodes 320a and 320b are respectively mounted as positive (+) and negative (-) electrodes on both inner walls of the vacuum cap 310 facing each other, and generate RF high frequency from a high frequency generator (not shown). When RF high-frequency waves are applied to the target area of the skin sucked into the cavity of the vacuum cap, the ions of the cell molecules constituting the adipose tissue become positive (+) and negative (-) charges by the alternating current of the RF electrode. It is attracted to the anode, causing a polarization phenomenon. When Joule heat is intensively generated in adipose tissue due to the polarization action, fat cells are decomposed, leading to treatment of obesity.
특히, 본 발명은 도 4 및 도 5와 같이 한쌍의 RF전극(320a,320b)의 극성을 스위칭할 수 있는 회로(500)를 구성하고, RF전극의 극성에 대한 스위칭은 고주파 인가 신호입력 버튼(465)의 푸시 회수에 연동하여 이루어진다. 한 예로 상기 RF전극(320a,320b)의 극성 스위칭은 고주파 인가 신호입력 버튼(465)을 1~5회 누를 때마다 이루어지도록 할 수 있다.In particular, the present invention constitutes a circuit 500 capable of switching the polarity of a pair of RF electrodes 320a and 320b as shown in FIGS. 4 and 5, and switching for the polarity of the RF electrode is performed using a high-frequency application signal input button ( 465) in conjunction with the number of pushes. For example, the polarity switching of the RF electrodes 320a and 320b may be performed every time the high-frequency application signal input button 465 is pressed 1 to 5 times.
즉, 시술자가 고주파 인가 신호입력 버튼(465)을 1~5회 누를 때마다 RF전극의 극성이 1회 스위칭되도록 할 수 있다. 예를들어 고주파 인가를 위해 버튼(465)을 3회 누를 때마다 RF전극의 극성이 스위칭되도록 하는 경우 3회까지는 전극의 극성이 바뀌지 않고 4회째 극성이 스위칭되도록 구성할 수 있다. 또, 상기 버튼(456)에 의한 고주파 인가 신호입력은 한 예로 각 버튼을 푸시할 때마다 소정 펄스 형태로 0.1~10초 동안 지속된다.That is, whenever the operator presses the high-frequency application signal input button 465 1 to 5 times, the polarity of the RF electrode can be switched once. For example, when the polarity of the RF electrode is switched every time the button 465 is pressed three times for high-frequency application, the polarity of the electrode does not change up to three times and the polarity of the fourth time can be switched. In addition, the high-frequency application signal input by the button 456 continues for 0.1 to 10 seconds in the form of a predetermined pulse each time each button is pushed, for example.
상기 고주파 인가 신호입력 버튼(465)은 시술자가 버튼을 누르기 쉽도록 손잡이 부분인 제2 몸체부(420)에 구성되는 것이 바람직하다.The high-frequency application signal input button 465 is preferably configured in the second body portion 420, which is a handle portion, so that the operator can easily press the button.
본 발명은 상기와 같이 고주파 인가 신호입력 버튼(465)의 푸시 회수에 연동하여 극성이 스위칭 되는 RF전극을 통하여 상기 진공캡에 흡착된 피부를 가로질러 교대로 고주파를 인가할 수 있도록 구성함으로써 RF 고주파의 출력 및 조사 시간을 작게 하더라도 흡착부의 피부 영역에 분극의 분포를 고르게하여 치료할 수 있다.The present invention is configured to alternately apply a high frequency frequency across the skin adsorbed to the vacuum cap through an RF electrode whose polarity is switched in conjunction with the number of pushes of the high frequency application signal input button 465 as described above. Even if the output and irradiation time are small, it can be treated by evening the distribution of polarization in the skin area of the adsorbent.
상기와 같이 흡착부의 피부 영역에 분극의 분포를 고르게할 경우 치료 과정에서 고주파의 조사 시간 및 출력을 작게할 수 있기 때문에 피시술자의 피부에 통증을 유발하는 것을 줄일 수 있고, 시술 피부의 발열로 인한 온도 상승 속도를 줄일 수 있는 장점이 있다.As described above, when the distribution of polarization in the skin region of the adsorption unit is even, the irradiation time and output of the high frequency can be reduced during the treatment process, so it is possible to reduce the pain in the skin of the person being treated, and the temperature caused by the heat of the treated skin It has the advantage of reducing the ascent rate.
상기 컨트롤러(380)에 구성되는 한쌍의 RF전극(320a,320b)의 극성을 스위칭하는 회로(500)는 시술자가 고주파 인가 신호입력 버튼(465)을 온/오프하는 신호를 받아 출력제어부(460)에서 제어한다.The circuit 500 for switching the polarity of the pair of RF electrodes 320a and 320b configured in the controller 380 receives a signal for the operator to turn on/off the high-frequency application signal input button 465 to the output control unit 460 controlled in
상기 스위칭 회로(500)는 컨트롤러(380)와 연결되는 출력제어부(460)와 트랜지스터 등을 이용한 개폐 회로나 전자식 스위치를 이용하여 구성되는 스위칭소자(461,462)로 구성할 수 있다.The switching circuit 500 may include an output control unit 460 connected to the controller 380 and switching elements 461 and 462 configured using an opening/closing circuit using a transistor or an electronic switch.
예를 들어 도 4와 같이 버튼(465)의 온 신호에 따라 출력제어부(460)를 통하여 RF전극에 전원이 공급되면 컨트롤러(380)는 + 극성과 연결된 스위칭소자(461)와 - 극성과 연결된 스위칭소자(462)의 접점 구동을 컨트롤 하여 RF전극(320a)은 + 극성, RF전극(320b)은 - 극성을 갖도록 한다.For example, when power is supplied to the RF electrode through the output control unit 460 according to the ON signal of the button 465 as shown in FIG. 4 , the controller 380 switches the switching element 461 connected to the + polarity and the switching connected to the - polarity. By controlling the contact driving of the element 462, the RF electrode 320a has a + polarity and the RF electrode 320b has a - polarity.
도 4의 상태에서 도 5와 같이 스위칭소자(461,462)의 접점을 바꾸어주면 RF전극(320a)은 - 극성, RF전극(320b)은 + 극성으로 스위칭된다.In the state of FIG. 4, when the contacts of the switching elements 461 and 462 are changed as shown in FIG. 5, the RF electrode 320a is switched to a - polarity, and the RF electrode 320b is switched to a + polarity.
상기와 같이 진공캡 내의 흡착된 피부와 접촉되는 RF전극(320a,320b)의 극성을 스위칭하는 이유는 도 6 내지 도 8을 참고하여 설명한다.The reason for switching the polarity of the RF electrodes 320a and 320b in contact with the skin adsorbed in the vacuum cap as described above will be described with reference to FIGS. 6 to 8 .
진공캡(310) 내로 흡착된 피부를 가로질러 RF전극으로 고주파를 인가하면 피부(245)를 구성하는 세포 분자들의 이온들이 RF전극의 교류 전류에 의하여 양 전하는 음극으로 음 전하는 양극으로 끌려가 분극 현상이 발생하는데, 이 분극의 분포는 도 6과 같이 양극의 RF전극(320a) 쪽에서 크고, 음극의 RF전극(320b) 쪽에서 작게 일어난다. 따라서 피부와 접촉되는 양극과 음극이 항상 고정된 위치에 있으면 양극과 접촉된 피부쪽의 발열 온도가 높을 뿐 아니라 치료효과 또한 양극과 접촉된 피부쪽이 높아지게 되는 현상이 발생할 수 있다. When a high frequency is applied to the RF electrode across the skin adsorbed into the vacuum cap 310, the ions of the cell molecules constituting the skin 245 are attracted to the negative electrode by the alternating current of the RF electrode, and the negative charge is attracted to the positive electrode, causing polarization. This occurs, and the distribution of polarization is large on the positive RF electrode 320a side and small on the negative RF electrode 320b side, as shown in FIG. 6 . Therefore, if the anode and cathode in contact with the skin are always in a fixed position, not only the heating temperature of the skin side in contact with the anode is high, but also the treatment effect may occur in which the skin side in contact with the anode becomes high.
본 발명은 이러한 치료 효과의 불균형을 개선하기 위해 스위칭 회로(500)를 구동하여 도 7과 같이 RF전극(320a)을 음극, RF전극(320b)을 양극이 되도록 스위칭하면 진공캡(310)의 위치를 변경시키지 않더라도 분극의 분포를 바꾸어 줄수 있다.The present invention drives the switching circuit 500 to improve the imbalance of the treatment effect, and as shown in FIG. 7 , when the RF electrode 320a is switched to be a negative electrode and the RF electrode 320b is switched to be a positive electrode, the position of the vacuum cap 310 is Even if you do not change the polarization distribution, you can change it.
즉, 스위칭 회로(500)를 통하여 고주파 인가 신호입력 버튼(465)의 푸시 회수에 연동하여 한쌍의 RF전극(320a,320b)의 극성을 바꾸어주면 도 8과 같이 진공캡(310) 내로 흡착된 피부(245) 영역에 분극의 분포가 고르게 일어나도록 하여 치료 효과를 극대화 할 수 있다. That is, if the polarity of the pair of RF electrodes 320a and 320b is changed in conjunction with the number of pushes of the high frequency application signal input button 465 through the switching circuit 500, the skin absorbed into the vacuum cap 310 as shown in FIG. The treatment effect can be maximized by allowing the distribution of polarization to occur evenly in the (245) region.
본 발명은 치료 과정에서 진공캡 내에 흡착된 피부에 진동 펄스를 가하기 때문에 RF 고주파에 의한 분극의 분포가 더 활성화되는 경향이 있다.In the present invention, since a vibration pulse is applied to the skin adsorbed in the vacuum cap during the treatment process, the distribution of polarization by RF high frequency tends to be more activated.
물론 치료과정에서 피부의 온도가 소정 온도(한예로 42℃)를 넘으면 RF전극(320a,320b)의 전원을 차단하도록 한다.Of course, when the skin temperature exceeds a predetermined temperature (for example, 42° C.) during the treatment process, the power of the RF electrodes 320a and 320b is cut off.
상기와 같이 구성되는 본 발명의 핸드피스(300)의 구동 과정은 도 9를 참고하여 설명한다.The driving process of the handpiece 300 of the present invention configured as described above will be described with reference to FIG. 9 .
먼저, 제1 몸체부(410)에 진공캡(310)을 끼워 결합하고, 손잡이 기능을 하는 제2 몸체부(420)의 각도를 적절히 조정한다(S10).First, the vacuum cap 310 is fitted and coupled to the first body 410, and the angle of the second body 420 serving as a handle is appropriately adjusted (S10).
이어서, 진공캡(310)의 개방부 가장자리에 표적 부위의 피부(245)를 밀착 시킨다(S20).Then, the skin 245 of the target site is closely attached to the edge of the opening of the vacuum cap 310 (S20).
이어서, 진공캡(310)의 공동부(315)가 기준음압이 될때까지 진공장치(350)를 구동(S30)하여 진공캡 내의 공동부(315)로 피부(245)가 흡인되도록 함으로써 RF전극(320a,320b)과 피부(245) 표면이 접촉되도록 한다.Then, the vacuum device 350 is driven (S30) until the cavity 315 of the vacuum cap 310 becomes the reference negative pressure, so that the skin 245 is sucked into the cavity 315 in the vacuum cap, so that the RF electrode ( 320a, 320b) and the surface of the skin 245 are brought into contact.
이어서, 시술자의 제어신호에 따라 컨트롤러(380)는 기준음압 가변장치(360)의 구동 여부를 판단한다(S40).Next, according to the operator's control signal, the controller 380 determines whether the reference sound pressure variable device 360 is driven (S40).
단계 S40에서 기준음압 가변장치(360)의 구동이 선택되지 않으면 단계 S70으로 이동한다. 단계 S40에서기준음압 가변장치(360)의 구동이 이루어지는 경우에는 기준음압의 변동 음압을 1초당 0.5~50회 즉, 0.5~50Hz의 범위 내에서 음압 펄스의 파장과 진폭을 선택하고(S50), 그 음압 펄스의 진폭에 따라 표적 부위의 피부가 상하 방향으로 유동하므로 피부의 마사지가 이루어진다(S60). 진공캡(310)과 피부와의 접촉부 사이에 밀착 불량이 발생하여 공동부(315) 내의 기준음압이 소정의 설정된 범위를 벗어나면 진공장치(350)가 자동으로 가동되어 기준음압을 유지하도록 하여야 한다. If the driving of the reference sound pressure variable device 360 is not selected in step S40, it moves to step S70. When the driving of the reference sound pressure variable device 360 is performed in step S40, the wavelength and amplitude of the sound pressure pulse within the range of 0.5 to 50 times per second, that is, 0.5 to 50 Hz, for the fluctuation of the reference sound pressure (S50), Since the skin of the target area flows in the vertical direction according to the amplitude of the sound pressure pulse, the skin is massaged (S60). When the reference sound pressure in the cavity part 315 is out of a predetermined range due to poor adhesion between the vacuum cap 310 and the contact part with the skin, the vacuum device 350 is automatically operated to maintain the reference sound pressure. .
이어서, 시술자의 제어신호에 따라 컨트롤러(380)는 RF전극(320a,320b)을 구동하는지 여부를 판단한다(S70). RF전극(320a,320b)은 RF전극(320a,320b)의 극성을 스위칭하는 회로(500)를 개재하여 컨트롤러(380)에 의해 제어된다. 상기 RF전극(320a,320b)의 극성 스위칭은 고주파 인가 신호입력 버튼(465)의 푸시 회수에 연동하여 이루어진다. Next, according to the operator's control signal, the controller 380 determines whether to drive the RF electrodes 320a and 320b (S70). The RF electrodes 320a and 320b are controlled by the controller 380 via a circuit 500 for switching the polarities of the RF electrodes 320a and 320b. The polarity switching of the RF electrodes 320a and 320b is performed in association with the number of pushes of the high-frequency application signal input button 465 .
RF전극(320a,320b)을 통한 RF 고주파가 표적 부위의 피부에 교대로 소정 펄스파가 0.1~10초 조사되면 치료(S90)가 시작되고, 치료시작 후 RF 고주파에 의해 표적 부위의 피부 온도가 42℃ 이상으로 상승할 경우 온도감지센서(331)가 이를 감지(S100)하고 컨트롤러(38)는 RF전극(320a,320b)의 구동을 일시 중지한다.When a predetermined pulse wave is alternately irradiated with a predetermined pulse wave for 0.1 to 10 seconds on the skin of the target area with the RF high frequency through the RF electrodes 320a and 320b, the treatment (S90) starts, and after the start of treatment, the skin temperature of the target area is lowered by the RF high frequency wave. When the temperature rises above 42° C., the temperature sensor 331 detects it (S100) and the controller 38 temporarily stops the operation of the RF electrodes 320a and 320b.
피부 온도가 42℃ 이하이면 RF전극(320a,320b)에 의한 치료 과정이 반복되지만 피부 온도가 42℃ 이상이면 RF전극(320a,320b)의 구동을 일시 중지하여 피부(245)가 냉각(S100)될 수 있도록 한다. 상기 피부의 냉각은 별도의 냉각장치를 통하거나 시간 지연에 따른 자연 냉각을 이용할 수 있다.If the skin temperature is below 42 ℃, the treatment process by the RF electrodes 320a and 320b is repeated, but when the skin temperature is 42 ℃ or more, the operation of the RF electrodes 320a and 320b is temporarily stopped to cool the skin 245 (S100) make it possible The skin may be cooled through a separate cooling device or natural cooling according to a time delay may be used.
상기 과정을 거쳐 치료가 이루진 후 시술자는 치료 종료(S120)를 판단한다. After the treatment is completed through the above process, the operator determines the end of treatment (S120).
이어서, 치료가 종료되면 음압이 해제(S130)되고, 시술자는 진공캡(310)을 핸드피스의 제1 몸체부(410)로부터 분리(S140)한다.Then, when the treatment is finished, the negative pressure is released (S130), and the operator separates the vacuum cap 310 from the first body portion 410 of the handpiece (S140).
도 9에서는 편의상 기준음압 가변장치(360)의 구동을 먼저 판단하고, RF전극(320a,320b)의 구동을 나중에 판단하는 것으로 설명하였다. 상기 RF전극과 기준음압 가변장치의 구동은 상기 예시된 구동 프로세스에 한정되지 않고 각각 단독적으로 구동하거나, 동시 구동, 교대 구동 중 어느 하나의 구동을 선택하여 동작할 수 있다. In FIG. 9, for convenience, the driving of the reference sound pressure variable device 360 is first determined, and the driving of the RF electrodes 320a and 320b is determined later. The driving of the RF electrode and the reference sound pressure variable device is not limited to the above-exemplified driving process, and each may be driven independently, or may be operated by selecting any one of simultaneous driving and alternating driving.
