Aesthetic treatment device and method
An aesthetic treatment device including: a multi illumination system having at least one source in the visible region, disposed around a periphery of a predetermined area of skin; an imaging device, sensitive to the illumination system, to discern features on or in the skin within the predetermined area of skin to be treated; multiple treatment light sources mounted on an optical bench and aimed and focused to a point of treatment in the predetermined area of skin; a mechanical guidance system to guide the multiple treatment light sources; and a pulse generator to control power output of the multiple treatment light sources based upon the treatment to be applied to the predetermined area of skin.
1. A method for performing a dermatological treatment on a predetermined area of skin, comprising:
placing an illumination system having an aperture on the predetermined area of the skin;
exposing the predetermined area of skin through the aperture;
illuminating the predetermined area of skin with the illumination system which has the aperture by emitting, from multiple illumination light sources disposed around a periphery of the aperture, multiple illumination beams having different wavelengths in the UV to infrared region in free space across the aperture over the predetermined area of skin and in a parallel direction to the skin surface;
generating an image of the illuminated predetermined area of the skin with an imaging device by imaging the illuminated predetermined area of the skin through the aperture and through a central hole of a hollow focusing lens; and
generating laser beams from multiple treatment laser sources having different wavelengths, the multiple treatment laser sources arranged on a circumference of an optical bench in pairs by same wavelength, wherein the illumination system, the laser sources, the optical bench and the hollow lens are housed together in a handpiece;
adjusting a power output of the laser beams based on the dermatological treatment to be applied to the predetermined area of skin;
propagating the laser beams through the aperture of the illumination system, focusing the laser beams under the skin with the hollow focusing lens, moving a focal point of the laser beams by tilting the hollow lens relative to the aperture of the illumination system, and performing the dermatological treatment with the propagated multiple treatment light sources based on the generated image.
2. The method according to claim 1 , the method further comprising bending and focusing the laser beams according to wavelength and penetrating the surface of the skin at multiple different locations, wherein each pair of focused laser beams has a focal point along a focal axis at a different depth under the skin from each other pair of focused laser beams.
3. The method according to claim 2 , wherein the focal points of the laser beams are under the surface of the skin.
4. The method according to claim 2 , wherein the propagating of the laser beams comprises directing the laser beams parallel to one another towards a lens, and bending and aiming the parallel laser beams at the focal points under the skin.
5. The method according to claim 4 , wherein the propagating of the laser beams comprises using the lens which is a circular lens to bend and aim the parallel beams at the focal points under the skin.
6. The method according to claim 4 , wherein the aiming points of the laser beams are each along an optical axis of the lens, but at a different distance from other pairs of focused beams from the lens.
7. The method according to claim 5 , wherein the aiming points of the laser beams are each along an optical axis of the lens, but at a different distance from other pairs of focused beams from the lens.
8. The method according to claim 4 , wherein the lens is a circular lens with an the central hole to provide a free line of sight for the imaging device to the predetermined area of skin.
9. The method according to claim 2 , wherein the illumination system has the aperture along an optical axis, and the imaging device is along the optical axis.
