Description

ＨＩＦＵ 스킨케어 디바이스용 카트리지 내에 설치되는 초음파 트랜스듀서 이송 메커니즘 장치An ultrasonic transducer transfer mechanism device installed in a cartridge for a HIFU skin care device
본 발명은 초음파를 이용한 스킨케어 디바이스에 관하며, 특히 고강도 집속형 초음파(High Intensity Focused Ultrasonic: HIFU)를 이용해서 피부 미용 및 치료적 목적의 처치를 도모하는 디바이스 관련 기술에 관한다. The present invention relates to a skin care device using ultrasound, and in particular, relates to a device-related technology for pursuing skin care and treatment for therapeutic purposes by using high intensity focused ultrasound (HIFU).
HIFU 디바이스는 강력 집속 초음파를 이용해서 인체에 직접적으로 열을 가하는 특성이 있다. 종래 HIFU 디바이스는 고강도(집속 영역 강도 1000W/cm2 이상)의 초음파를 한 초점에 집속하여 종양 조직을 괴사(necrosis) 혹은 제거(ablation)함으로써, 간암, 자궁암, 유방암 등의 암을 치료하는 장비로 알려졌다. HIFU 장비를 이용한 치료 방법은 비침습적 방법으로 외과적 수술 방법에 비하여 환자의 회복 속도가 빠르며 안전하다는 인식으로 인해 그 수요가 늘어나는 추세이다. The HIFU device has the characteristic of directly applying heat to the human body using strong focused ultrasound. Conventional HIFU device is a device that treats cancers such as liver cancer, uterine cancer, breast cancer, etc. by focusing high-intensity (focusing area intensity 1000W/cm 2 or more) ultrasound into one focus and necrosis or ablation of tumor tissue. Became known. The treatment method using HIFU equipment is a non-invasive method, and the demand is increasing due to the recognition that the patient's recovery speed is faster and safer than the surgical method.
초음파는 인체조직을 통과할 때에는 해롭지 않으나, 초점을 형성하는 고강도의 초음파는 조직의 종류에 상관없이 괴사를 일으킬 수 있을 만큼 충분한 에너지를 발생한다. HIFU 디바이스는 전기 에너지를 초음파 주파수 범위의 기계적 진동 에너지로 변환시키는 초음파 트랜스듀서의 선형/회전 운동을 통해 신체의 타깃 초점에 고강도의 에너지를 집속시키는 것이 중요하며, 그러므로 트랜스듀서의 정확한 운동제어가 필요하다. 초점거리, 초점 위치의 정확도, 조사시간, 초점영역에서의 온도 등도 중요한 요소이다. 그리고 이들 요소에 대한 연구와 기술은 많이 발전되어 왔다.Ultrasound is not harmful when passing through human tissue, but high intensity ultrasound that forms a focus generates enough energy to cause necrosis regardless of the type of tissue. For HIFU devices, it is important to focus high-intensity energy at the target focus of the body through the linear/rotational motion of an ultrasonic transducer that converts electrical energy into mechanical vibration energy in the ultrasonic frequency range. Therefore, precise motion control of the transducer is required. Do. Focal length, accuracy of focus position, irradiation time, and temperature in the focus area are also important factors. And research and technology for these factors have been developed a lot.
위와 같은 HIFU 기술은 다양하게 응용되고 있다. 종양 조직에 대한 치료 목적뿐만 아니라, 주름개선 등의 피부 미용과 비만 치료 목적으로도 사용되고 있다. 그런 예로서 하기의 특허문헌 1은 장비 본체에 연결해서 사용하는 HIFU 시술 핸드피스를 개시하고 있다. HIFU technology as described above has been applied in various ways. It is used not only for treatment of tumor tissues, but also for skin care such as wrinkle improvement and obesity treatment. As such an example, the following Patent Document 1 discloses a HIFU surgical handpiece connected to the main body of the equipment and used.
그런데 하기 특허문헌 1의 HIFU 시술 핸드피스는 병원에서 사용하는 고가의 장비와 연결돼서 사용하는 것으로 고강도 초음파를 시술 대상자의 피부에 가하기 위한 전력을 장비 본체로부터 공급받기 때문에 휴대해서 사용할 수 없다는 문제점이 있었다. 따라서 시술자는 그런 장비가 있는 병원까지 가야만 하는 불편함을 겪어야 했다. However, the HIFU procedure handpiece of Patent Document 1 below is used in connection with expensive equipment used in hospitals, and there is a problem that it cannot be used by carrying the power to apply high-intensity ultrasound to the skin of the subject to be treated from the equipment body. . Therefore, the practitioner had to experience the inconvenience of having to go to a hospital with such equipment.
또한 카트리지 외부에 설치되는 모터로 카트리지 내부에 있는 트랜스듀서를 구동하는 구조로 소비전력이 커지며 모터 구동에 따라 발생하는 열 때문에 방열대책이 까다로운 단점도 있었다. 특히 트랜스듀서의 정확한 위치 제어를 보장하기 위한 구동 수단을 구현함과 동시에 물 속에 위치하는 이송자 모듈이 소재의 항상성을 유지해야 했는데 이것이 기술적으로 오랫동안 해결하기 어려운 과제였다. In addition, since the motor installed outside the cartridge drives the transducer inside the cartridge, power consumption is increased, and heat dissipation measures are difficult due to the heat generated by driving the motor. In particular, while implementing a driving means to ensure accurate position control of the transducer, the transport module located in the water had to maintain the homeostasis of the material, which has been a technically difficult task for a long time.
본 발명의 발명자는 이러한 문제를 해결하기 위해 매우 오랜 기간 연구하고 노력하여 기술개발을 한 끝에 본 발명을 완성하기에 이르렀다. In order to solve this problem, the inventor of the present invention has completed the present invention after a very long period of research and effort to develop technology.

It is added that if the cartridge for a skin care device of the present invention is implemented by the function/configuration/structure described in the claims, it can be used by attaching and detaching it to the body of various physical/electronic configurations. For example, a handpiece that is used by connecting a commercial power source may be the main body.
본 명세서에서 도시되어 있는 형태와 이하에서 설명되는 구성은 하나의 바람직한 실시예라는 점을 감안하자. 본 발명의 스킨케어 디바이스용 카트리지의 원리와 구성을 설명하려면, 먼저 본체 구성과 함께 설명해야 하기 때문에 아무래도 본체에 대한 실시예 설명이 필요할 것 같았다. 그러므로 예시적으로 본체 실시예를 제시한다.It is to be noted that the form shown in the specification and the configuration described below are one preferred embodiment. In order to explain the principle and configuration of the cartridge for a skin care device of the present invention, it was necessary to explain the embodiment of the body first, since it must be described together with the body configuration. Therefore, a main body embodiment is presented as an example.
도시되어 있는 것처럼, 내부에 제어기에 설치되어 있는 본체(100) 외부는 사용자가 손으로 잡고 사용하기 편리한 물리적인 구조로 되어 있다. 바람직하게는, 길이는 200~250mm, 폭은 60~80mm, 카트리지(200)가 장착되어 있는 상태에서의 두께는 50~80mm인 것이 좋다. 케이스 재질은 ABS, PC 등의 플라스틱 부재로 이루어져 있으며 실링 부재로 실리콘을 사용할 수 있다As shown, the outside of the main body 100 installed in the controller inside has a physical structure that is convenient for the user to hold and use by hand. Preferably, the length is 200-250mm, the width is 60-80mm, and the thickness in the state in which the cartridge 200 is mounted is preferably 50-80mm. The case material is made of plastic materials such as ABS and PC, and silicone can be used as a sealing member.
본체(100)의 표면에는 전원 버튼(101)이 구성된다. 전원 버튼(101)이 설치된 표면과 같은 표면에 디스플레이(105)가 설치되어 있다. 그리고 측면에는 초음파 세기를 강/중/약으로 스텝을 조절하는 스텝 버튼(103)이 설치되어 있다. A power button 101 is formed on the surface of the main body 100. The display 105 is installed on the same surface as the surface on which the power button 101 is installed. In addition, a step button 103 is installed on the side to adjust the step of the ultrasonic intensity to strong/medium/weak.
전원 버튼(101)을 0.5초 이상 누르면 부저음과 함께 디스플레이(105)가 켜진다. 디스플레이(105)에는 본 발명의 휴대용 HIFU 스킨케어 디바이스(1)의 다양한 상태가 숫자/문자/기호/아이콘/그림 등으로 표시될 수 있다.When the power button 101 is pressed for 0.5 seconds or more, the display 105 is turned on with a buzzer sound. On the display 105, various states of the portable HIFU skin care device 1 of the present invention may be displayed as numbers/letters/symbols/icons/pictures, and the like.
전원 버튼(101) 및 스텝 버튼(103)의 조작과, 배터리 상태 등에 따라 디스플레이(105)가 어떻게 표시되는지를 설명함으로써, 본 발명의 기능과 동작이 어떻게 이루어지는지 알 수 있다. 그러므로 이에 대해 예시적으로 상세히 설명한다.By explaining how the display 105 is displayed depending on the operation of the power button 101 and the step button 103 and the battery status, it is possible to know how the functions and operations of the present invention are performed. Therefore, it will be described in detail by way of example.
앞에서 설명한 것처럼, 전원 버튼(101)을 0.5초 이상 누르면 디바이스는 부팅되고 부저음과 함께 디스플레이(105)를 통해 상태표시가 점등된다. 바람직하게는 전원 ON시 상태표시 점등은 사용자가 사용할 수 있는 Shot 수가 표시되도록 한다. As described above, when the power button 101 is pressed for 0.5 seconds or more, the device is booted up and the status display is turned on through the display 105 with a buzzer sound. Preferably, the status display lights up when the power is turned on so that the number of shots the user can use is displayed.
본 발명에서 1SHOT이란 카트리지(200)에 장착된 초음파 조사 동작 동안 모터가 1mm 간격 주기로 10mm 거리를 이동하여 다시 원점으로 돌아오는 초음파 조사 이벤트를 뜻하며, "SHOT 수"라 함은, 이런 고강도의 초음파를 조사한 이벤트의 개수를 뜻한다. 전원이 ON된 상태에서 전원 버튼(101)을 수초 이상 (예컨대 3초) 누르면 부저음과 함께 전원 오프 상태표시로 변경되면서 전원이 오프된다. In the present invention, 1SHOT refers to an ultrasonic irradiation event in which the motor moves 10mm distance at 1mm intervals and returns to the origin during the ultrasonic irradiation operation mounted on the cartridge 200, and "the number of shots" refers to such high intensity ultrasonic waves. It means the number of events investigated. When the power button 101 is pressed for a few seconds or more (for example, 3 seconds) while the power is turned on, the power is turned off while changing to a power off state display with a buzzer sound.
본체(100) 내부에 있는 배터리가 방전되면 디스플레이(105)의 배터리 아이콘이 방전되었음을 나타내도록 표시되고, 수초 간격으로 부저음을 내보내며 사용자에게 충전하라고 경고한다. 충전용 크래들(도 2의 300)에 본체(100)를 거치한 후, 충전용 크래들 입력단에 어댑터 연결시에는 충전중임을 나타내도록 디스플레이(105)가 점등된다. When the battery in the main body 100 is discharged, the battery icon of the display 105 is displayed to indicate that the battery icon is discharged, and a buzzer sound is emitted every few seconds to warn the user to charge. After the main body 100 is mounted on the charging cradle (300 in FIG. 2), when the adapter is connected to the charging cradle input terminal, the display 105 is lit to indicate that charging is in progress.
사용자가 동작 모드로 사용하는 방법은 이러하다. 도 1의 본체(100)를 파지한 다음에, 카트리지(200)의 헤드 부위를 사용하고자 하는 오브젝트에 완전히 밀착한 후에, 전원 버튼(101)을 짧게 1번 누르면 부저음과 함께 SHOT 아이콘이 표시 점등되고, 모터 구동과 함께 초음파가 조사되며, 표시창에 사용한 사용 횟수가 숫자로 표시된다. 이러한 동작 모드에서, 사용자는 미리 스텝 버튼(103)을 이용해서 초음파 세기를 강/중/약으로 조절할 수 있다. 이러한 초음파 세기는 디스플레이(105)를 통해 아이콘으로 표시될 수 있다. This is how the user uses it as an operation mode. After holding the main body 100 of Fig. 1, after completely contacting the head of the cartridge 200 with the object to be used, pressing the power button 101 once briefly displays the SHOT icon with a buzzer sound and lights up. , The ultrasonic wave is irradiated with the motor driving, and the number of times used is displayed in numbers on the display window. In this operation mode, the user can adjust the ultrasonic intensity to strong/medium/weak by using the step button 103 in advance. The ultrasonic intensity may be displayed as an icon through the display 105.
카트리지(200)의 교환주기가 되면 디스플레이(105)에 "CHANGE"라는 글자가 표기되어 점등되고, 사용자에게 카트리지 교환을 안내한다. 바람직한 실시예에서, 본 발명의 카트리지 최대 사용 횟수는 10,000shot이다. 더 적게 혹은 더 많이 사용될 수도 있다.When the replacement cycle of the cartridge 200 is reached, the word “CHANGE” is displayed on the display 105 and is lit, and the user is guided to change the cartridge. In a preferred embodiment, the maximum number of uses of the cartridge of the present invention is 10,000 shots. It can be used less or more.
도 2는 크래들(300)을 포함해서, HIFU 스킨케어 디바이스(1)의 구성을 분리해서 나타내었다. 2 shows the configuration of the HIFU skin care device 1, including the cradle 300, separated.
HIFU 트랜스듀서가 내장된 카트리지(200)는, 도시되어 있는 것처럼, 본체(100)의 헤드 부분의 아래쪽 수용부에 장착하고 분리된다. 카트리지(200)를 본체 헤드 수용부에 끼워 장착하면 카트리지(200) 커넥터 단자부(210)가 본체 커넥터부와 전기적인 접촉을 형성한다. 카트리지(200)에는 고강도 집속 초음파 조사 시의 매질 역할을 하는 증류수를 보관하고 있으며, 이 증류수가 혹시 발생할지도 모를 과열 현상을 냉각시키는 기능도 수행한다. 그러므로 카트리지(200)의 표면에는 증류수 투입구(205)가 설치되어 내부의 밀폐된 증류수 탱크(미도시)와 연결되어 있다. The cartridge 200 with a built-in HIFU transducer, as shown, is mounted and separated from the lower receiving portion of the head portion of the main body 100. When the cartridge 200 is inserted into the body head receiving portion and mounted, the connector terminal portion 210 of the cartridge 200 forms electrical contact with the body connector portion. The cartridge 200 stores distilled water serving as a medium during high-intensity focused ultrasonic irradiation, and this distilled water also performs a function of cooling an overheating phenomenon that may occur. Therefore, a distilled water inlet 205 is installed on the surface of the cartridge 200 to be connected to an inner sealed distilled water tank (not shown).
크래들(300)에는 어댑터를 연결하여 충전할 수 있는 충전부(320)가 설치된다. 이 충전부(320)는 바람직하게는 Micro 5pin USB 충전 커넥터로 구성될 수 있다. 카트리지(200)가 본체(100) 헤드에 장착된 상태에서, 휴대용 HIFU 스킨케어 디바이스의 충전과 거치를 위해 크래들(300)에 결합할 수 있다. 카트리지(200) 헤드를 크래들(300)의 거치 홈(310)에 끼운다. 그러면 거치 홈(310)에 내장된 UV 램프(미도시)가 점등되면서 카트리지(200) 헤드 부분을 UV로 소독함과 동시에, 크래들 충전단자(307)를 통해 본체(100) 내부의 배터리를 충전한다(크래들 충전단자(307)는 도 3의 본체 충전단자(107)와 전기적으로 연결된다). 그때 본체(100) 디스플레이(105)를 통해 충전상태가 표시된다. A charging unit 320 capable of charging by connecting an adapter is installed in the cradle 300. The charging unit 320 may preferably be configured with a Micro 5pin USB charging connector. In a state where the cartridge 200 is mounted on the head of the body 100, it may be coupled to the cradle 300 for charging and mounting a portable HIFU skin care device. Insert the head of the cartridge 200 into the mounting groove 310 of the cradle 300. Then, a UV lamp (not shown) built in the mounting groove 310 is lit, disinfecting the head of the cartridge 200 with UV, and charging the battery inside the main body 100 through the cradle charging terminal 307 (The cradle charging terminal 307 is electrically connected to the main body charging terminal 107 of FIG. 3). At that time, the state of charge is displayed through the display 105 of the main body 100.
크래들(300)과 본체(100)가 서로 결합된 상태에서 분리되기 전에는 휴대용 HIFU 스킨케어 디바이스(1)는 동작하지 않는다. The portable HIFU skin care device 1 does not operate until the cradle 300 and the main body 100 are separated from each other in a coupled state.
도 3은 본체(100)와 카트리지(200)를, 도 2와는 반대 방향에서 바라본 도면이다. 본체(100)의 헤드 수용부(109) 개구를 통해 카트리지(200)를 장착한다. 그러면 도 2에서 도시된 카트리지 커넥터 단자부(210)와 본체의 커넥터 단자부(110)가 전기적인 컨택을 형성함으로써 본체의 제어부가 카트리지의 내부 모듈을 제어할 수 있게 된다.3 is a view of the main body 100 and the cartridge 200 viewed from the opposite direction to that of FIG. 2. The cartridge 200 is mounted through the opening of the head receiving portion 109 of the main body 100. Then, the cartridge connector terminal portion 210 shown in FIG. 2 and the connector terminal portion 110 of the main body form an electrical contact, so that the controller of the main body can control the internal module of the cartridge.
카트리지(200)에서 조사되는 고강도 집속 초음파는 작용부의 카트리지 윈도우(220)를 통해 오브젝트에 전달된다.The high intensity focused ultrasonic waves irradiated from the cartridge 200 are transmitted to the object through the cartridge window 220 of the working portion.
한편, 사용자는 카트리지 교환버튼(212)를 눌러서 카트리지(200)를 본체(100)에서 분리할 수 있다. Meanwhile, the user can separate the cartridge 200 from the main body 100 by pressing the cartridge exchange button 212.
도 4는 본 발명의 바람직한 일 실시예에서 카트리지(200)의 구성을 다섯 가지 방향에서 입체적으로 나타내었다. 도 4(c)가 배면이 된다. 4 shows the configuration of the cartridge 200 in a three-dimensional manner in five directions in a preferred embodiment of the present invention. Fig. 4(c) is the back side.
카트리지(200)의 PCB(250)에는 내부 전자 요소들(미도시)을 포함한 제어부가 설치되어 있으며, 카트리지 커넥터 단자부(210)가 외부로 노출되어 있다. 이 PCB(250)는 카트리지(200) 하우징 외부의 배면돌출부(240)에 설치된다. 배면돌출부(240)는 카트리지(200) 배면 외부 표면에서 돌출하여 형성되는데, PCB(250)가 끼워지도록 PCB(250) 두께만큼의 수용홈(미도시)이 마련되어 있다. 그리고 배면돌출부(240)의 수용홈에 PCB(250)를 장착한다. 그리고 PCB(250)와 전기적으로 연결된 케이블이 하우징 내부에 위치하는 트랜스듀서 이송 메커니즘 장치와 연결된다. A control unit including internal electronic elements (not shown) is installed on the PCB 250 of the cartridge 200, and the cartridge connector terminal portion 210 is exposed to the outside. The PCB 250 is installed on the rear protrusion 240 outside the housing of the cartridge 200. The rear protrusion 240 is formed to protrude from the rear outer surface of the cartridge 200, and a receiving groove (not shown) equal to the thickness of the PCB 250 is provided so that the PCB 250 is inserted. Then, the PCB 250 is mounted in the receiving groove of the rear protrusion 240. In addition, a cable electrically connected to the PCB 250 is connected to a transducer transfer mechanism device located inside the housing.
카트리지(200)의 배면 반대방향으로 2개의 챔버가 설치된다. 제1챔버(291)와 제2챔버(292)는 서로 연통되어 있으며, 증류수를 수용하는 탱크 역할을 한다. 제1챔버(291)에는 피에조 모터(216)를 포함한 트랜스듀서 이송 메커니즘 장치가 설치된다. 트랜스듀서 이송 메커니즘 장치는 후술하는 이송자, 이송자 모듈을 포함한다. Two chambers are installed in the opposite direction to the rear surface of the cartridge 200. The first chamber 291 and the second chamber 292 are in communication with each other and serve as a tank for receiving distilled water. A transducer transfer mechanism device including a piezo motor 216 is installed in the first chamber 291. The transducer transport mechanism device includes a transporter and a transporter module to be described later.
하우징의 외부 정면이 작용부가 되는 제2챔버(292)는 제1챔버(291)보다 폭이 좁게 정면을 향해 돌출한다. 이 외부 돌출 표면이 작용부가 되며, 오브젝트와 면 접촉한다. 제2챔버(292) 안에는 HIFU 트랜스듀서의 하우징이 위치한다. The second chamber 292, in which the outer front of the housing is an acting part, protrudes toward the front with a width smaller than that of the first chamber 291. This external protruding surface becomes the acting part and makes surface contact with the object. The housing of the HIFU transducer is located in the second chamber 292.
상기 제1챔버(291)의 배면돌출부에 대응되는 입구에는 상기 챔버들(291, 292) 안에 수용되어 있는 증류수가 바깥으로 누설되지 않도록 실링하는 실링 부재(207)가 끼워져 있다. A sealing member 207 that seals the distilled water contained in the chambers 291 and 292 to prevent leakage to the outside is fitted at an inlet corresponding to the rear protrusion of the first chamber 291.
도 5는 도 4의 카트리지(200)의 중앙 부분을 배면에서 정면 반향으로 절단한 다음 나타내는 분리 사시도이며, 도 6은 도 5의 분리 사시도를 결합한 단면도이다.FIG. 5 is an exploded perspective view showing a central portion of the cartridge 200 of FIG. 4 after being cut in a frontal echo, and FIG. 6 is a cross-sectional view combined with the exploded perspective view of FIG. 5.
도 5 및 도 6을 통해서 카트리지(200) 내부의 구성과 실링 부재(207)의 설치 방법 및 위치를 용이하게 파악할 수 있다. 또한 배면돌출부(240)와 PCB(250)의 구성도 정확하게 이해할 수 있다.5 and 6 it is possible to easily grasp the internal configuration of the cartridge 200 and the installation method and location of the sealing member 207. In addition, the configuration of the rear protrusion 240 and the PCB 250 can be accurately understood.
증류수 투입구(205)는, 바람직하게는 주사기를 이용해서 증류수 투입이 실시되기 때문에 작은 구멍이어도 충분하고, 더욱 정확하게는 대략 직경 1~3mm 볼트를 이용하여 개폐할 수 있는 너트가 설치된다. 또한 이 증류수 투입구(205)에 방수 러버가 끼워지는 것이 좋다.Since the distilled water inlet 205 is preferably injected with distilled water using a syringe, a small hole may be sufficient, and more precisely, a nut that can be opened and closed using a bolt of approximately 1 to 3 mm in diameter is provided. In addition, it is preferable that a waterproof rubber is fitted into the distilled water inlet 205.
또한 배면 하우징을 전면 하우징과 결합하기 위한 체결 너트(206)가 6개 설치되는 것이 좋다(도 5에서는 카트리지(200) 하우징의 절반만 도시되었으므로 체결 너트(206)가 일부만 보인다).In addition, 6 fastening nuts 206 for coupling the rear housing to the front housing are preferably installed (in FIG. 5, only half of the cartridge 200 housing is shown, so only a part of the fastening nut 206 is visible).
초음파 트랜스듀서(201)는 이송자 모듈(211)과 결합되어 있다. 그러므로 이송자 모듈(211)이 움직임에 수반하여 초음파 트랜스듀서(201)의 위치가 변경된다. 이송자 모듈(211)의 상부에는 이송자(202)가 피에조 모터(216)와 연결되는 카본 축(215)에 설치되어 선형 변위한다. 도면에서는 이송자(202)가 카본 축(215)을 따라 수평방향으로 변위한다. The ultrasonic transducer 201 is coupled to the transporter module 211. Therefore, as the transporter module 211 moves, the position of the ultrasonic transducer 201 is changed. At the top of the transporter module 211, a transporter 202 is installed on a carbon shaft 215 connected to the piezo motor 216 to linearly displace. In the drawing, the transporter 202 is displaced in the horizontal direction along the carbon axis 215.
카본 축(215) 위쪽에는 이송자 모듈 레일(217)이 설치되어 있다. 또한 이송자 모듈(211)의 상단부에는 레일 연결부(212)가 구성된다. 이 레일 연결부(212)가 이송자 모듈 레일(217)에 설치됨으로써 이송자 모듈(211)이 좌우로 틀어지는 것을 방지해준다. 이송자(202)가 물리적인 변위를 실행할 때 레일 연결부(212)도 이송자의 수평 변위에 추종하여 함께 변위한다.A transporter module rail 217 is installed above the carbon shaft 215. In addition, a rail connection part 212 is configured at the upper end of the transporter module 211. The rail connection part 212 is installed on the transfer module rail 217 to prevent the transfer module 211 from twisting left and right. When the transporter 202 performs a physical displacement, the rail connection part 212 is also displaced according to the horizontal displacement of the transporter.
그러므로 이송자 모듈(211)은 이송자(202)를 통해 카본 축(215)을 따라 수평 변위하고 동시에 상단부의 레일 연결부(212)를 통해 이송자 모듈 레일(217)을 따라 수평 변위한다. Therefore, the transporter module 211 is horizontally displaced along the carbon axis 215 through the transporter 202 and at the same time horizontally displaced along the transporter module rail 217 through the rail connection 212 at the upper end.
카본 축(215)의 한쪽 단부는 카본 축 고정대(218)에 고정되고, 다른 한쪽은 피에조 모터(216)에 연결되어 있다. 압전 리니어 모터인 피에조 모터(216)는 모터 수납부(219)에서 구동된다. 모터 수납부(219)는 밀봉되어 있다. 따라서 제1챔버(291)에 들어 있는 증류수가 피에조 모터(216)의 구동을 방해하지 못하게 되고, 피에조 모터(216)의 정밀한 기능을 보장하는 효과를 거둔다.One end of the carbon shaft 215 is fixed to the carbon shaft holder 218 and the other is connected to the piezo motor 216. The piezo motor 216, which is a piezoelectric linear motor, is driven in the motor accommodating part 219. The motor housing 219 is sealed. Accordingly, the distilled water contained in the first chamber 291 does not interfere with the driving of the piezo motor 216, thereby ensuring the precise function of the piezo motor 216.
한편 제1챔버(291) 안에 설치된 이송자 감지 센서가 이송자의 위치를 감지한다.Meanwhile, a transporter detection sensor installed in the first chamber 291 detects the position of the transporter.
피에조 모터(216)가 구동되면 이송자(202)가 정해진 위치로 변위하며, 그에 따라 전술한 바와 같이 이송자 모듈(211) 아래쪽에 설치되는 초음파 트랜스듀서(201)의 위치가 결정된다. When the piezo motor 216 is driven, the transporter 202 is displaced to a predetermined position, and accordingly, the position of the ultrasonic transducer 201 installed below the transporter module 211 is determined as described above.
초음파 트랜스듀서(201)에서 오브젝트를 향해 조사되는 고강도 초음파는 작용부 중앙에 설치되는 윈도우(203)를 통과하게 되는데, 이 윈도우(203)에는 폴리이미드 또는 플리메틸펜텐 등의 초음파 투과 필름이 사용될 수 있다.The high-intensity ultrasonic waves irradiated from the ultrasonic transducer 201 toward the object passes through a window 203 installed in the center of the working part, and an ultrasonic transmissive film such as polyimide or polymethylpentene may be used for the window 203. have.
도 7은 본 발명의 바람직한 어느 실시예에 따른 피에조 모터(216)와 이송자(202)의 관계를 예시적으로 나타낸다. 도 7(a)는 한쪽 끝에 피에조 모터(216)가 설치된 카본 축(215)에 이송자(202)가 설치된 상태를, 도 7(b) 및 도 7(c)는 이송자(202)의 내부 구성에 대한 이해를 돕기 위해 각 부재가 분리되어 있는 상태를, 도 7(d)는 이송자(202)의 각 부재가 결합된 상태의 구성을 나타낸다.FIG. 7 exemplarily shows the relationship between the piezo motor 216 and the transporter 202 according to a preferred embodiment of the present invention. Fig. 7(a) shows a state in which the transporter 202 is installed on the carbon shaft 215 in which the piezo motor 216 is installed at one end, and Figs. 7(b) and 7(c) show the internal configuration of the transporter 202. In order to help understand the situation, each member is separated from each other, and FIG. 7 (d) shows a configuration in which each member of the transporter 202 is coupled.
본 발명의 실시예에서 이송자(202)의 중앙 홀(213)로 카본 축(215)이 관통한다. 이 중앙 홀(213)을 통해 피에조 모터(216)에 의해 발생되는 변위가 이송자(202)에 선형적으로 전달된다. 이 중앙 홀(213)을 기준으로 이송자(202)의 몸체는 도시되어 있는 것처럼 상하 두 조각으로 서로 분리될 수 있으며, 또한 서로 끼워져서 카본 축(215)에 설치된다.In the embodiment of the present invention, the carbon shaft 215 passes through the central hole 213 of the transporter 202. The displacement generated by the piezo motor 216 is linearly transmitted to the conveyer 202 through this central hole 213. Based on this central hole 213, the body of the transporter 202 can be separated from each other into two pieces, upper and lower, as shown, and is also fitted to each other to be installed on the carbon shaft 215.
서로 대향하는 한 쌍의 이송자 조각(202a, 202b)에는 각각 볼록한 이송자 고정 가이드(202c)와 오목한 이송자 고정 홀(202d)이 설치되어 있다. 제1이송자 조각의 이송자 고정 가이드(202c)는 제2이송자 조각의 이송자 고정 홀(202d)에 끼워진다. 마찬가지로 제1이송자 조각의 이송자 고정 홀(202d)에는 제2이송자 조각의 이송자 고정 가이드(202c)가 삽입됨으로써 각각의 이송자 조각이 결합하여 하나의 이송자(202)를 구성한다. A convex conveyer fixing guide 202c and a concave conveyer fixing hole 202d are provided in the pair of conveyer pieces 202a and 202b facing each other, respectively. The transporter fixing guide 202c of the first transporter piece is fitted into the transporter fixing hole 202d of the second transporter piece. Likewise, the transporter fixing guide 202c of the second transporter piece is inserted into the transporter fixing hole 202d of the first transporter piece, so that each transporter piece is combined to form one transporter 202.
이송자 조각(202a, 202b)의 등 부분은 오목부(202e, 202f)의 형상을 갖는다. 그리고 이 오목부(202e, 202f)에 각각 상하로 금속 재질의 판스프링(214)을 끼움으로써 상하 이송자 조각(202a, 202b)이 더욱 견고하게 일체로 결합된다. 상기 이송자 판스프링(214)은 물이 채워진 제1챔버(291) 안에 장시간 위치하기 때문에 내부식성의 재질로 이루어지는 것이 좋다. 본 발명의 발명자는 스테인리스 강 SUS316으로 제작된 이송자 판스프링(214)를 사용하였다. 이 이송자 판스프링(214)의 유지력(Holding Force)는 바람직하게는 100~140 kgf 사이로 정해진다. 이송자는 물속에서 장기간 변위한다는 점을 감안한다면 이송자 판스프링(214)의 유지력이 100kgf보다 작으면 이송자(202) 조각(202a, 202b)의 결합이 느슨해져서 구동의 정확성이 확보되지 못할 우려가 커진다. 이송자 판스프링(214)의 유지력이 140kgf보다 크면 이송자(202)가 파손될 우려가 있다.The back portions of the transporter pieces 202a and 202b have the shape of concave portions 202e and 202f. And by inserting a plate spring 214 made of a metal material up and down in the concave portions 202e and 202f, the upper and lower transporter pieces 202a and 202b are more rigidly coupled together. Since the transporter leaf spring 214 is located in the first chamber 291 filled with water for a long time, it is preferable to be made of a corrosion-resistant material. The inventor of the present invention used a feeder plate spring 214 made of stainless steel SUS316. The holding force of the transporter leaf spring 214 is preferably set between 100 and 140 kgf. Considering that the transporter is displaced in water for a long period of time, if the holding force of the transporter leaf spring 214 is less than 100kgf, the coupling of the transporter 202 pieces 202a and 202b becomes loose, and thus there is a greater concern that the accuracy of driving may not be secured. If the holding force of the transporter leaf spring 214 is greater than 140kgf, the transporter 202 may be damaged.
위와 같은 구성을 통해서 본 발명의 카트리지(200) 내부에서 초음파 트랜스듀서(201)가 선형으로 이동하는 메커니즘이 완성된다. 도 8을 살펴보자. Through the above configuration, a mechanism for linearly moving the ultrasonic transducer 201 in the cartridge 200 of the present invention is completed. Let's look at Figure 8.
초음파 트랜스듀서(201)는 동작을 개시하면 도 8(a)의 초기 위치에서 도 8(b), 도 8(c)의 위치로 선형적으로 이송된다. 피에조 모터(216)가 구동하면 이송자 모듈에 의해 초음파 트랜스듀서(201)는 카본 축(215)을 통해 1mm씩 수평방향으로 이동한다. 그러면 초음파 트랜스듀서(201)를 통해 만들어지는 초음파 초점(F)의 위치 또한 변경되며, 따라서 오브젝트에 형성되는 초음파 초점 영역도 변경된다. 그렇게 고강도 집속 초음파를 조사하고, 또한 초음파 초점(F)의 위치를 바꿈으로써 피부 미용효과를 거둔다.When the ultrasonic transducer 201 starts its operation, it is linearly transferred from the initial position of FIG. 8(a) to the positions of FIGS. 8(b) and 8(c). When the piezo motor 216 is driven, the ultrasonic transducer 201 is moved horizontally by 1 mm through the carbon shaft 215 by the transporter module. Then, the position of the ultrasonic focal point F generated by the ultrasonic transducer 201 is also changed, and thus the ultrasonic focal region formed on the object is also changed. Thus, by irradiating high-intensity focused ultrasound and changing the position of the ultrasound focus (F), a skin cosmetic effect is achieved.
도 9에 도시된 것처럼, 초음파 트랜스 듀서(201)를 통해 조사되는 고강도 초음파가 집속되는 초점(F)는 오브젝트의 피부층(S) 중 초음파 초점 영역(S1)에만 초점을 형성한다. 본 발명에서는 특히 1Shot 동안에, 총 10회 초음파를 조사하도록 설정될 수 있다. 1mm 당 1회씩 조사하고, 그럴 때마다 모터 구동을 통해 1mm씩 변위(X)함으로써 1Shot 동안에 10mm의 초점영역(Y)이 형성된다. As illustrated in FIG. 9, a focus F on which high-intensity ultrasonic waves irradiated through the ultrasonic transducer 201 are focused forms a focus only on the ultrasonic focus area S1 of the skin layer S of the object. In the present invention, it may be set to irradiate a total of 10 ultrasonic waves, especially during 1Shot. Irradiation is performed once per 1 mm, and each time it is displaced (X) by 1 mm through motor driving, a focus area (Y) of 10 mm is formed during 1 shot.
즉, 초음파 초점 영역(S1) 피부 조직에서만 고강도 초음파가 가해져서, 예컨대 65~100℃ 열에 의한 상처가 생긴다. 이와 같이 피부 조직에 자극을 주고, 인체가 그 자극에 자연스럽게 반응하도록 함으로써 주름뿐 아니라 피부 탄력 향상을 도모할 수 있다. 한편 고강도 초음파 집속의 원리상 초음파 트랜스듀서(201)의 윈도우와 접촉하는 오브젝트의 표피에는 아무런 상처를 남기지 않는다. That is, the high-intensity ultrasound is applied only to the skin tissue of the ultrasound focus area S1, so that, for example, a wound caused by heat at 65 to 100° C. In this way, it is possible to improve skin elasticity as well as wrinkles by giving the skin tissue a stimulus and allowing the human body to respond naturally to the stimulus. Meanwhile, according to the principle of high-intensity ultrasonic focusing, no scar is left on the epidermis of an object that contacts the window of the ultrasonic transducer 201.
