22 : 지지부 31 ∼ 33 : 1차 내지 3차렌즈 22: support part 31 to 33: primary to tertiary lens

본 발명은 레이저 핸드피스에 관한 것으로, 더욱 상세하게는 레이저를 다수의 조사빔으로 분산 변환시킨 후 일정한 면적에 대해 조사함으로써 시술시간을 절감하고, 치료효과는 극대화시킬 수 있는 레이저 핸드피스에 관한 것이다.The present invention relates to a laser handpiece, and more particularly, to a laser handpiece which can reduce the procedure time and maximize the therapeutic effect by dispersing and converting the laser into a plurality of irradiation beams. .

일반적으로 피부질환에 사용되는 치료법으로는 레이저, 자외선, 아이피 엘(IPL)을 이용하는 광치료법이 있다.In general, the treatment used for skin diseases include laser, ultraviolet light, IPL (phototherapy) using the light therapy.

상기 광치료법 중에서 레이저에 관하여 살펴보면, 레이저(LASER : Light amplification by stimulated emission of radiation)는 일반 태양광선과는 달리 단색광이며 평행광이고 파의 위상이 같다는 특징을 갖고 있다.When looking at the laser of the light therapy, the laser (LASER: Light amplification by stimulated emission of radiation (LASER) is characterized by a monochromatic light, parallel light and the same phase of the wave, unlike the normal sunlight.

즉, 한가지 파장만을 갖고 있어서 태양광선과는 달리 파장에 따라 붉은 색 혹은 노란색 등 한 색깔로 보이게 된다.In other words, because it has only one wavelength, it looks red or yellow, depending on the wavelength, unlike sunlight.

이처럼 한가지 파장만을 갖고있다는 것이 치료에 매우 중요한 변수가 된다.This single wavelength is a very important variable for treatment.

즉, 다른 정상 피부조직은 손상시키지 않으면서 우리가 치료하고자 하는 목표(예를 들어 비정상적인 혈관 혹은 색소)를 선택적으로 파괴할 수 있는 근거가 된다.In other words, it is the basis for the selective destruction of the target (eg abnormal blood vessels or pigments) we want to treat without damaging other normal skin tissues.

레이저가 피부에 조사되었을 때 일어나는 상호작용(interaction)을 살펴보면, 광선이 피부에 조사될 때에 광선은 그 파장에 따라 피부의 특정 물질에 흡수된다.Looking at the interactions that occur when a laser is irradiated to the skin, when the light is irradiated to the skin, the light is absorbed by a particular substance on the skin according to its wavelength.

피부를 구성하고 있는 물질은 각기 특정 파장의 빛을 잘 흡수하는 성질을 갖고 있는데 이 물질을 발색단(chromophore)라고 한다.Each of the substances that make up the skin absorbs light of a certain wavelength, which is called a chromophore.

예를 들어 탄산가스 레이저에서 방출되는 적외선 에너지는 주로 물에 흡수된다.For example, infrared energy emitted by carbon dioxide lasers is mainly absorbed by water.

그런데 우리 몸의 70% 정도가 물로 구성되어 있기 때문에 조사된 레이저 에너지들은 우리 몸의 어느 부위에나 흡수되어 열을 발생시킴으로써 조직을 파괴시키게 된다.Since about 70% of our body is made up of water, the irradiated laser energy is absorbed in any part of our body and generates heat, destroying tissue.

따라서, CO2 레이저는 비특이적으로 조직을 파괴시킬 필요가 있을 때에 사용된다.Therefore, CO 2 lasers are used when there is a need to destroy tissue nonspecifically.

혈관 내에 있는 적혈구에는 532nm, 577nm 또는 585nm의 파장의 빛이 잘 흡수된다.Erythrocytes in the blood vessels absorb light at wavelengths of 532 nm, 577 nm or 585 nm.

그리고 기미나 주근깨의 원인이 되는 멜라닌이라는 색소는 532nm, 755nm, 그리고 1064nm 파장의 빛에 잘 흡수된다.The pigment melanin, which causes blemishes and freckles, is well absorbed by light at wavelengths of 532 nm, 755 nm, and 1064 nm.

그러므로 이런 레이저 광선과 피부 조직간의 상호작용을 이용하면 치료하고자 하는 목표만을 파괴하고, 주변 조직에는 가능한 손상을 주지 않도록 하는 선택적 광열분해(Photothermolysis) 치료가 가능해질 수 있다.Thus, the interaction between these laser beams and skin tissues may enable selective photothermolysis treatments that destroy only the targets to be treated and avoid possible damage to surrounding tissues.

따라서, 최근에는 레이저를 이용한 치료장치가 출시되어 사용중에 있는데 이를 살펴보면,Therefore, recently, a laser treatment device has been released and is in use.

상기 패널조작부의 입력신호에 대해 신호처리가 이루어지며, 상기 신호처리에 의해 레이저의 슈퍼펄스 스캐닝 및 레이저 발진 제어신호를 출력하는 중앙제어부; 및 상기 슈퍼펄스 스캐닝 제어신호에 의해 구동신호를 출력시키는 스캐너구동부와, 상기 구동신호에 의해 방향 또는 각도를 조절할 수 있도록 회전력을 발생시키는 스텝모터와,A central controller configured to perform signal processing on an input signal of the panel operator, and output a super pulse scanning and laser oscillation control signal of a laser by the signal processing; And a scanner driver for outputting a driving signal by the super pulse scanning control signal, and a step motor for generating a rotational force to adjust a direction or an angle by the driving signal.

상기 굴절부로부터 출력된 레이저가 반사되며, 상기 반사된 레이저를 해당 시술부위에 슈퍼펄스 스캔할 수 있도록 방향 또는 각도가 조절되는 미러로 이루어진 슈퍼펄스 스캔부(400)를 포함하여 이루어진다.The laser output from the refraction unit is reflected, and comprises a super-pulse scan unit 400 made of a mirror whose direction or angle is adjusted so as to super-scan the reflected laser to the surgical site.

여기서, 상기 굴절부에는 레이저빔을 최종 방출하기 위해 굴절부 선단에는 조작이 자유로운 핸드피스가 설치된다. Here, the handpiece freely manipulated is installed at the tip of the refracting part to finally emit the laser beam.

상기 핸드피스는 치료용 레이저 펄스의 폭, 간격, 파장을 선택적으로 조절하여 출력시키는 단말부이다.The handpiece is a terminal unit for selectively adjusting the width, interval, and wavelength of the laser beam for treatment.

종래 핸드피스는, 도 1b에 도시된 바와 같이, 전원이 입력되면 레이저가 출력되도록 플래시 램프(102)와, 반사경(101)으로 구성되어, 단일의 레이저빔(90) 조사가 가능하게 된다.As shown in FIG. 1B, the conventional handpiece includes a flash lamp 102 and a reflector 101 so that a laser is output when power is input, so that a single laser beam 90 can be irradiated.

따라서, 넓은 시술면적에 대해 레이저빔을 조사하기 위해서는, 제어부의 제어에 따라 스텝모터 및 미러가 작동하여 조사각도를 수시로 변경시켜 일정간격으로 레이저빔을 조사하여야 하므로, 시술시간이 길어지게 되는 문제점이 있었다.Therefore, in order to irradiate a laser beam over a large treatment area, the step motor and the mirror operate under the control of the controller to change the irradiation angle from time to time to irradiate the laser beam at a predetermined interval, which leads to a long procedure time. there was.

또한, 종래 핸드피스로는 단일점으로만 레이저빔이 출력되는데, 촛점의 직경을 미세하게 하는데 한계가 있어 미세한 조사점(도트)를 형성하기가 어려우므로, 넓은 면적의 환부에 대해서는 시술시간이 오래걸리고, 흉터가 남게 되는 문제점이 있었다.In addition, the laser beam is output to a single handpiece only by a single point, and there is a limit in making the diameter of the focus fine, so that it is difficult to form a fine irradiation point (dot), so that the procedure takes a long time for a large area affected. There was a problem of getting scars and scars.

본 발명은 상기한 종래 기술의 문제점을 해소하기 위해 안출된 것으로, 단일의 레이저빔을 분산시켜 다수의 미세한 조사점으로 이루어진 조사부를 형성함으로써, 넓은 면적의 시술부위에 대해 최소한의 시술횟수로 시술할 수 있으며, 아울러 미세한 조사점을 형성하여 시술함으로써 흉터 등 후유증이 전혀 없도록 한 레이저 핸드피스를 제공하는데 그 목적이 있다.The present invention has been made to solve the above-described problems of the prior art, by dispersing a single laser beam to form an irradiation section consisting of a plurality of minute irradiation points, to be performed with a minimum number of procedures for a large area of the treatment site In addition, it is also an object of the present invention to provide a laser handpiece in which there are no aftereffects such as scars by forming a fine irradiation point and performing the procedure.

이하 본 발명의 바람직한 실시예를 첨부된 도면을 토대로 상세하게 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명을 설명함에 있어, 종래와 동일한 구성에 대해서는 동일한 구성부호를 사용하고, 그 반복 설명은 생략하기로 한다.In describing the present invention, the same components as those in the related art are denoted by the same reference numerals, and repeated description thereof will be omitted.

첨부된 도 2는 본 발명에 따른 레이저 핸드피스에 대한 단면도이고, 도 3은 본 발명에 따른 레이저 핸드피스에 의해 형성된 레이저빔 조사부를 나타낸 도면이다.2 is a cross-sectional view of the laser handpiece according to the present invention, and FIG. 3 is a view showing a laser beam irradiation unit formed by the laser handpiece according to the present invention.

도 2에 나타낸 바와 같이, 본 발명에 따른 레이저 핸드피스(A)는, 내측에 렌즈수납부(20)가 형성되고, 하단에는 지지부(22)가 형성되며 상기 레이저 발생부(200)와 연결된 본체(2); 레이저빔(b1)을 확산시키는 1차렌즈(31)와; 상기 1차렌즈(31)를 통해 확산된 레이저빔(b1)을 회절 및 굴절시켜 다수개의 조사빔(b2)을 형성하도록 하는 2차렌즈(32)와; 상기 2차렌즈(32)를 통과한 조사빔(b2)을 X-Y 교차점에 조사되도록 정렬하여 소정 영역의 레이저빔 조사부(b3)를 형성하는 3차렌즈(33)로 구성된다. As shown in FIG. 2, the laser handpiece A according to the present invention includes a lens housing 20 formed at an inner side thereof, a support 22 formed at a lower end thereof, and a main body connected to the laser generator 200. (2); A primary lens 31 for diffusing the laser beam b1; A secondary lens 32 diffracting and refracting the laser beam b1 diffused through the primary lens 31 to form a plurality of irradiation beams b2; The radiation beam b2 passing through the secondary lens 32 is arranged to be irradiated at the X-Y crossing point to form a tertiary lens 33 forming a laser beam irradiation part b3 of a predetermined region.

상기 본체(2)는 1차 내지 3차렌즈(31∼33)를 수용하는 통체로써, 하단의 지 지부에는 통기공(220)이 형성된다.The main body 2 is a cylinder for accommodating the primary to tertiary lenses 31 to 33, and a vent hole 220 is formed at a lower supporting portion.

상기 1차렌즈(31)는, 레이저빔(b1)을 확산시킬 수 있도록 볼록렌즈로 형성된다.The primary lens 31 is formed of a convex lens so as to diffuse the laser beam b1.

상기 2차렌즈(32)는, 볼록렌즈로 된 픽셀렌즈가 다수개로 조합되어 이루어진 것으로, 상기 1차렌즈(31)를 통과하여 단일로 입사된 레이저빔(b1)을 상기 픽셀렌즈를 통해 회절 및 굴절시켜 분산시킴으로써 다수개의 조사빔(b2)으로 분할시킨다.The secondary lens 32 is formed by combining a plurality of convex pixel lenses, and diffracts the laser beam b1 incident through the primary lens 31 through the pixel lens. It is divided into a plurality of irradiation beams b2 by refracting and dispersing.

또한, 2차렌즈(32)의 표면코팅 두께에 따라 회절 및 굴절 정도를 조절할 수 있다.In addition, the degree of diffraction and refraction may be adjusted according to the surface coating thickness of the secondary lens 32.

그리고, 2차렌즈(32)를 통과하면서 필요에 따라 조사빔(b2)의 갯수가 정해지게 되는데, 레이저빔 조사부(b3)가 장방형으로 형성되어야 하므로, 가로 × 세로는 7 × 7 또는 9 × 9 개로 설정함이 바람직하다. The number of irradiation beams b2 is determined as necessary while passing through the secondary lens 32. Since the laser beam irradiation portion b3 should be formed in a rectangle, the width × length is 7 × 7 or 9 × 9. It is preferable to set to open.

상기 3차렌즈(33)는, 전술한 2차렌즈(32)를 통과한 다수개의 조사빔(b2)이 외부로 퍼져나가지 않고 레이저빔 조사부(b3) 내에 조사될 수 있도록 집중시키게 되며, 통상 오목렌즈로 이루어진다.The tertiary lens 33 concentrates the plurality of irradiation beams b2 passing through the above-described secondary lens 32 so that they can be irradiated into the laser beam irradiation unit b3 without spreading to the outside and are usually concave. It consists of a lens.

즉, 레이저빔 조사부(b3)는 장방형이 가장 적당하고, 그 내측으로만 조사빔(b2)이 조사될 수 있도록 집중시키게 되며, 특히 레이저빔 조사부(b3)를 X-Y 좌표값으로 설정한 후 X-Y 교차점에 조사빔(b2)이 조사될 수 있도록 한다.That is, the laser beam irradiator b3 has the most suitable rectangular shape, and concentrates the irradiation beam b2 to be irradiated only inside thereof. In particular, the laser beam irradiator b3 is set to the XY coordinate value and then the XY intersection point. The irradiation beam b2 can be irradiated.

이와 같이 구성된 본 발명의 핸드피스의 작용을 설명하면 다음과 같다.Referring to the operation of the handpiece of the present invention configured as described above are as follows.

본 발명에 적용되는 레이저는 파장이 10.6 nm인 CO2 레이저, 파장이 1320nm 인 Nd YAG 레이저, 파장이 1064 nm인 Nd YAG 레이저, 파장이 2940 nm인 Er YAG 레이저가 사용된다.As the laser applied to the present invention, a CO 2 laser having a wavelength of 10.6 nm, an Nd YAG laser having a wavelength of 1320 nm, an Nd YAG laser having a wavelength of 1064 nm, and an Er YAG laser having a wavelength of 2940 nm are used.

또한, 레이저의 조사는 의사의 처방에 따라 침투깊이, 면적, 열적손상 등을 고려하여 선택적으로 사용된다.In addition, laser irradiation is selectively used in consideration of penetration depth, area, thermal damage, etc. according to a doctor's prescription.

전술한 레이저 중에서 침투깊이는, Er YAG 레이저＞ Nd YAG 레이저(1064 nm)＞ Nd YAG 레이저(1320nm) ＞ CO2 레이저(10.6 nm) 순이다.The penetration depth among the above-mentioned lasers was Er YAG laser> Nd YAG laser (1064 nm)> Nd YAG laser (1320 nm)> CO 2 laser (10.6 nm).

레이저발생장치에서 발생된 레이저빔(b1)은 1차렌즈(31)를 통과하면서, 비교적 넓은 직경을 갖도록 확산된다.The laser beam b1 generated in the laser generating device passes through the primary lens 31 and is diffused to have a relatively large diameter.

이후, 2차렌즈(32)를 통과하면서, 픽셀렌즈를 통해 다수개의 조사빔(b2)으로 분할된다.Then, while passing through the secondary lens 32, it is divided into a plurality of irradiation beam (b2) through the pixel lens.

이후, 3차렌즈(33)를 통과하면서 분할된 조사빔(b2)은 대략 장방형의 레이저빔 조사부(b3)를 형성하게 된다.Thereafter, the irradiation beam b2 split while passing through the tertiary lens 33 forms a substantially rectangular laser beam irradiation part b3.

따라서, 비교적 넓은 부위에 대한 시술이 수행될 수 있어 시술시간이 단축될 수 있고, 또한 분할된 조사빔으로 출력되므로 환부에 대한 손상을 절감할 수 있게 된다.Therefore, the procedure can be performed on a relatively large area, so that the procedure time can be shortened, and the damage to the affected part can be reduced since the procedure is output as a divided irradiation beam.

또한, 핸드피스 본체(2)의 일측에는 공기를 분사하는 공기분사부(미도시)가 더 설치된다. 즉, 공기분사부를 통해 적정압력으로 공기를 분사함으로써 레이저 시술시 발생되는 연기를 제거하여 보다 쾌적하고 정확한 시술이 가능하게 된다. In addition, an air injection unit (not shown) for injecting air is further provided at one side of the handpiece main body 2. That is, by injecting air at an appropriate pressure through the air injection unit to remove the smoke generated during the laser treatment it is possible to more comfortable and accurate procedures.

상기 공기분사부는 에어콤프레셔와 이에 연결된 노즐로 구성되며, 이는 공지 의 기술구성이므로 그 상세한 설명은 생략한다.The air injection unit is composed of an air compressor and a nozzle connected thereto, and since it is a known technical configuration, its detailed description is omitted.
