Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem with the conventional optical system of a laser irradiator for beautiful skin that laser light may cause blindness or damage eyeballs when it is cast to the air by mistake because laser light is generally in parallel or a bit constricted and cast to the skin or the irradiation area cannot be easily controlled by changing the distance from a lens to the skin because the irradiation area on the skin is roughly constant irrespectively the distance from the lens to the skin. <P>SOLUTION: The optical system once focuses laser light before it is cast to the skin. When it is cast to the skin, it becomes scattered light. Consequently, even when laser is cast in the air by mistake, the light is immediately scattered and the possibility that the eyes are damaged is extremely lowered even if the light gets into the eyes. By varying the distance from the lens to the skin, the irradiation area on the skin can be easily adjusted. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、美肌用のレーザー照射装置の光学系に関するThe present invention relates to an optical system of a laser irradiation apparatus for beautifying skin.

従来、肌のシワの軽減、シミの減少、ニキビ跡の修復といった目的のために、美肌用のレーザー照射装置が開発されている。Conventionally, a laser irradiation apparatus for beautifying skin has been developed for the purpose of reducing skin wrinkles, reducing spots, and repairing acne scars.

これらのレーザー照射装置は、シミの軽減を目的とした場合には、レーザー光は肌に散在するメラニンに吸収され、その結果メラニンが分解されてシミが軽減する。また、肌のシワの軽減やニキビ跡の修復を目的とした場合には、レーザー光は、皮膚内の真皮層の大部分を形成している、コラーゲンもしくはその周囲の水分に吸収され、結果として、コラーゲンを生成する線維芽細胞の活性化をうながし、コラーゲンの増加により、シワの軽減やニキビ跡の修復が発生し、結果として、美肌効果につながることになる。When these laser irradiation apparatuses aim to reduce spots, laser light is absorbed by melanin scattered on the skin, and as a result, melanin is decomposed to reduce spots. For the purpose of reducing wrinkles on the skin and repairing acne scars, the laser light is absorbed by collagen or its surrounding water, which forms the majority of the dermis layer in the skin. It stimulates the activation of fibroblasts that produce collagen, and the increase in collagen causes wrinkles reduction and acne scar repair, resulting in a skin beautifying effect.

このように、美肌用のレーザー照射装置には、いくつもの有益な効果があるが、その光学系に関しては、従来レーザー光線を平行もしくは、少しだけ絞って肌に照射するのが一般的になっている。このような光学系であれば、肌に照射した時の肌に対する効果は、充分に得られるが、万が一レーザー照射装置のレーザー部とレンズ部からなるハンドピース部を肌に接触させないで、空中で誤照射してしまったような場合、レーザー光線は、強度が非常に高いために、光線が眼に入ってしまうと、失明や眼球の損傷といった事故を引き起こしかねない。As described above, the laser irradiation apparatus for beautifying skin has a number of beneficial effects. However, with respect to the optical system, it has become common to irradiate the skin with a laser beam that is parallel or slightly reduced. . If it is such an optical system, the effect on the skin when irradiated to the skin can be obtained sufficiently, but in the unlikely event that the handpiece part consisting of the laser part and the lens part of the laser irradiation device does not contact the skin, in the air In case of accidental irradiation, the intensity of the laser beam is so high that if it enters the eye, it may cause an accident such as blindness or eyeball damage.

また、このような光学系の場合、レーザーから照射された光線を肌に照射する場合の照射面積は、レンズから肌までの距離に拘らずほぼ一定であり、ハンドピースの簡単な設計変更(つまり、レンズから目標とする肌までの距離の変更)により、簡単に照射面積をコントロールすることができないといった問題がある。In the case of such an optical system, the irradiation area when the light beam emitted from the laser is irradiated on the skin is almost constant regardless of the distance from the lens to the skin, and a simple design change of the handpiece (that is, There is a problem that the irradiation area cannot be easily controlled by changing the distance from the lens to the target skin).

このような問題を解決するために、本発明では、レーザーから照射された光がレンズを通過して肌に照射される際に、肌に照射する直前に一度光が焦点を結ぶことを光学系の特徴とする。In order to solve such a problem, in the present invention, when the light emitted from the laser passes through the lens and is irradiated onto the skin, the optical system once focuses the light immediately before irradiating the skin. It is characterized by.

このように、肌に照射する直前に一度光が焦点を結ぶ光学系であれば、万が一レーザー照射装置のレーザー部とレンズ部からなるハンドピース部を肌に接触させないで、空中で誤照射してしまったような場合にも、レーザー光線は、ハンドピースから離れるにつれて、どんどん拡散していくことになり、もしも、その光線が眼に入ってしまった場合にも、光線の強度は十分に低くなっており、眼球に損傷を与える可能性は極めて低くなる。In this way, if the optical system focuses light once just before irradiating the skin, the handpiece part consisting of the laser part and the lens part of the laser irradiation device should not be brought into contact with the skin and accidentally irradiated in the air. Even in such a case, the laser beam will spread more and more as it moves away from the handpiece, and if it enters the eye, the intensity of the beam will be sufficiently low. The possibility of damaging the eyeball is very low.

また、肌に照射される直前に一度光が焦点を結ぶ光学系であれば、ハンドピースの簡単な設計変更(つまり、レンズから目標とする肌までの距離の変更)により、簡単に照射面積をコントロールすることができる。レーザー光線の照射面での照射強度については、レーザーの制御により、自在にコントロール可能であるので、照射面積を変化させてもフルーエンス(単位面積あたりの照射エネルギー)を一定に保つことも可能である。In addition, if the optical system focuses light just before it is irradiated onto the skin, the irradiation area can be easily reduced by a simple design change of the handpiece (that is, a change in the distance from the lens to the target skin). Can be controlled. Since the irradiation intensity on the irradiation surface of the laser beam can be freely controlled by controlling the laser, the fluence (irradiation energy per unit area) can be kept constant even if the irradiation area is changed.

本発明の光学系を使用すれば、ハンドピース部を肌に接触させないで、空中で誤照射してしまい、それが万が一眼に入ることがあっても、眼に損傷を与えることがなく、また、ハンドピースの簡単な設計変更(レンズから目標とする肌までの距離の変更)により、容易に照射面積をコントロールすることができる。If the optical system of the present invention is used, the handpiece part will not be in contact with the skin, it will be accidentally irradiated in the air, and even if it may enter the eye, it will not damage the eye, The irradiation area can be easily controlled by a simple design change of the handpiece (change of the distance from the lens to the target skin).

美肌用レーザー照射装置の構成を図1に示す。美肌用レーザー照射装置は、大きくレーザー光線を肌に照射するハンドピース部2とハンドピース部2内に収納されたレーザーを制御するコントローラ部1から構成される。ハンドピース部2内には、レーザー及びレンズが収納されており、トリガースイッチ3を押すことにより、ハンドピース部2より、レーザー光線が0.1〜2秒の間の任意の一定時間だけ肌に照射される。The structure of the laser irradiation apparatus for beautiful skin is shown in FIG. The laser irradiating apparatus for beautifying skin is composed of a handpiece part 2 that irradiates the skin with a laser beam and a controller part 1 that controls a laser housed in the handpiece part 2. A laser and a lens are housed in the handpiece unit 2, and when the trigger switch 3 is pressed, the laser beam is irradiated from the handpiece unit 2 to the skin for an arbitrary period of time between 0.1 and 2 seconds. Is done.

美肌用レーザー照射装置のハンドピース部2内に収納された光学系を図2に示す。光学系は、レーザー4とレンズ(1)5とレンズ(2)6から構成され、レーザー4から照射されたレーザー光線は、光線軌跡8のような軌跡をたどり、レンズ(1)5とレンズ(2)6を通過して、肌7に照射される。ここで、レンズ(2)6を通過した光線が、肌7に照射される直前に一度焦点を結び、その後拡散した光線が肌7に照射されることが、この光学系の特徴である。The optical system accommodated in the handpiece part 2 of the laser irradiation apparatus for beautiful skin is shown in FIG. The optical system includes a laser 4, a lens (1) 5, and a lens (2) 6, and a laser beam irradiated from the laser 4 follows a locus such as a ray locus 8, and the lens (1) 5 and the lens (2 ) 6 is passed and irradiated to the skin 7. Here, the optical system is characterized in that the light beam that has passed through the lens (2) 6 is focused once before being irradiated on the skin 7, and then the diffused light beam is irradiated on the skin 7.

従来の美肌用レーザー照射装置のハンドピース部2内に収納された光学系の例を図3および図4に示す。それぞれの光学系において、レーザー4から照射された光線は、レンズ(3)9を通過した後に肌7に照射されるか、レンズ(4)10およびレンズ(5)11を通過した後に肌7に照射されるが、いずれにせよ肌7に照射される際の光線の状態は、ほぼ平行状態にあるか、少し絞られた状態にある。このような光学系であると、万が一ハンドピース部2が肌から離れた状態でレーザーが発光してしまったような場合に、その光線が眼に入ってしまうと大変危険である。また、肌7に照射される光線の照射面積を変更したい場合、レンズ(3)9と肌7の距離、もしくはレンズ(5)11と肌7の距離を大きく変更しなければならず、ハンドピース部2の設計の変更を容易に行うことができない。An example of an optical system housed in the handpiece part 2 of a conventional laser irradiation apparatus for skin beautification is shown in FIGS. In each optical system, the light beam irradiated from the laser 4 is applied to the skin 7 after passing through the lens (3) 9, or is applied to the skin 7 after passing through the lens (4) 10 and the lens (5) 11. In any case, the state of the light rays when irradiating the skin 7 is almost parallel or slightly narrowed. In the case of such an optical system, if the laser beam is emitted with the handpiece part 2 away from the skin, it is very dangerous if the light enters the eye. Further, when it is desired to change the irradiation area of the light beam applied to the skin 7, the distance between the lens (3) 9 and the skin 7 or the distance between the lens (5) 11 and the skin 7 must be greatly changed. The design of the part 2 cannot be changed easily.

しかし、今回発明した図2の光学系であれば、万が一ハンドピース部2が肌7から離された状態でレーザーが発光してしまった場合でも、ハンドピースを出た光線は拡散していく一方で、急激に単位面積あたりの照射エネルギーは減少し、仮に眼に入ったとしても、眼に損傷を与える可能性は極めて低くなる。また、肌7上での照射面積を変更したい場合は、レンズ(2)6と肌7の距離を少し変化させるだけで、照射面積を容易に変更することができる。However, in the case of the optical system of FIG. 2 invented this time, even if the laser is emitted in the state where the handpiece part 2 is separated from the skin 7, the light emitted from the handpiece is diffused. Thus, the irradiation energy per unit area suddenly decreases, and even if it enters the eye, the possibility of damaging the eye becomes extremely low. Moreover, when it is desired to change the irradiation area on the skin 7, the irradiation area can be easily changed by slightly changing the distance between the lens (2) 6 and the skin 7.
