본 발명은 파장가변 레이저를 이용한 지방 융해 장치에 관한 것으로, 더욱 상세하게는 광파라메트릭 발진기에 의해서 다양한 파장의 레이저를 생성하는 레이저 장치에서 생성된 다양한 파장의 레이저를 이용하여 부위별 또는 지방량에 따라 파장을 다르게 적용하는 기술에 관한 것으로, 특히 상기 레이저 장치에서 가변 된 레이저 파장들을 각각의 파이버로 전송하는 것에 관한 것이다.The present invention relates to a fat melting apparatus using a wavelength tunable laser, and more particularly, by using a laser of various wavelengths generated in a laser device that generates lasers of various wavelengths by an optical parametric oscillator, The present invention relates to a technique of differently applying wavelengths, and more particularly, to transmitting variable laser wavelengths to respective fibers in the laser device.
지방 흡입술(liposuction)은 인체의 지방층에 있는 지방을 제거하는 기술이다. 상기와 같은 지방 흡입술은 직접적으로 지방을 제거하기 때문에 운동 또는 식이요법 등으로 하는 것보다 빠르게 제거가 있어야 하는 특정 부위의 지방을 쉽게 제거할 수 있는 장점이 있다. 또한, 운동이나 식이요법 등은 일차적으로 지방세포의 크기를 줄이는 방법이므로 지방세포가 완전히 제거되지 않는 한 추후에 쉽게 지방층이 두꺼워지지만 상기와 같은 지방흡입술에 의해서 시술할 경우 근본적으로 지방세포 수를 줄일 수 있기 때문에 운동이나 식이요법 등에 의한 것보다 쉽게 지방을 제거할 수 있다.Liposuction is a technique for removing fat from the fat layer of the human body. Liposuction as described above has the advantage that it is easy to remove the fat of a specific area that should be removed faster than to exercise or diet because it directly removes fat. In addition, exercise or diet is primarily a method of reducing the size of fat cells, so the fat layer is easily thickened later unless the fat cells are completely removed, but when the liposuction procedure is performed, the number of fat cells is basically reduced. This can make it easier to remove fat than by exercise or diet.
상기와 같은 지방 흡입술은 일반적으로 가는 관 형태의 캐뉼라를 사용하여 지방층에 삽입한 후 이를 전후방향으로 움직임으로써 지방세포를 분리 및 파괴하여 지방을 흡입하는 방식이다.Liposuction as described above is a method of inhaling fat by separating and destroying fat cells by inserting them into the fat layer by using a cannula in the form of a thin tube and then moving them forward and backward.
상기 방식의 지방 흡입술의 편리성을 위해서 진동식 또는 초음파식 지방 흡입 장치들이 추가되는 기술이 고안되고 있지만 여전히 사용자의 힘이 많이 작용하는 문제점이 있다.For the convenience of the liposuction method of the above-mentioned method has been devised a technique in which the vibration or ultrasonic liposuction apparatus is added, there is still a problem that the user's power is much working.
상기의 문제점들을 보완하기 위해서 레이저 지방융해 기술은 레이저 에너지를 이용하여 지방층의 지방 세포를 파괴하는 기술이다. 파괴된 지방은 림프 시스템에 의해서 자연적으로 체외로 배출되거나 흡입으로 제거될 수도 있다. 지방층까지 레이저 에너지를 전달하기 위해서 중공형 바늘 또는 캐뉼라가 사용되며 상기 중공형 바늘 또는 캐뉼라까지 레이저 에너지 전달은 파이버가 사용되기도 한다. 지방 흡입 방식에 대비되는 상기의 레이저 지방융해 방식은 외상의 현저한 감소 및 더욱 큰 지방 제거 효과가 있으며 지방층으로 바늘을 삽입함으로써 손상될 수 있는 작은 혈관을 소작 (cauterize)하는데 있어서 레이저 지방분해가 효과적이라고 할 수 있다. 또한 상기와 같은 경우 실질적으로 혈액 손실을 최소화할 수 있다.In order to solve the above problems, the laser lipolysis technique is a technique of destroying fat cells of the fat layer by using laser energy. Destroyed fat may be naturally excreted by the lymphatic system or removed by inhalation. A hollow needle or cannula is used to deliver laser energy to the fat layer, and a fiber is also used for laser energy delivery to the hollow needle or cannula. Compared to liposuction, the above laser lipolysis method has a significant reduction in trauma and greater fat removal effect, and laser lipolysis is effective in cauterizing small blood vessels that can be damaged by inserting a needle into the fat layer. can do. In addition, such a case can substantially minimize blood loss.
레이저 지방 융해 기술은 레이저가 파장에 따라 에너지가 지방에 흡수되는 정도가 다르기 때문에 파장을 선택적으로 사용하여 넓은 영역 또는 좁은 영역 그리고 많은 지방량 또는 적은 지방량을 분해할 수 있다. 기존 기술은 여러 가지 파장을 선택적으로 하기 위해서 여러 가지 파장의 레이저 장치를 혼합해서 사용하였다. 상기와 같은 경우 선택적으로 지방을 융해하기 위해서 여러 개의 레이저 장치가 필요하다는 단점을 가지고 있다. 따라서, 본 발명에서는 단일 레이저 장치에서 여러 가지의 파장을 출력할 수 있는 파장가변 레이저를 이용하여 선택적으로 지방 융해하는 것에 대해서 기술한다.Laser fat fusion technology uses lasers to selectively break down large areas or narrow areas and large or small amounts of fat because the laser absorbs energy into the fat at different wavelengths. The existing technology used a mixture of laser devices of various wavelengths to selectively select various wavelengths. In this case, there are disadvantages in that several laser devices are required to selectively melt fat. Accordingly, the present invention describes a selective fat melting using a wavelength tunable laser capable of outputting various wavelengths in a single laser device.

Such a wavelength tunable laser uses a nonlinear optical medium suitable for phase matching conditions, and uses the laser to sum sum generation (SFG), difference frequency generation (DFG), and optical in the nonlinear optical medium. Optical parametric generation and amplification (OPG & OPA) methods can be used to extend the wavelength-variable region from ultraviolet to infrared without the need for a separate resonator. In particular, an additional resonator including a nonlinear optical medium such as an optical parametric oscillator (OPO) can be configured to resonate the light generated by the light mediating effect in the resonator, thereby widening the wavelength control range.
