Laser therapy system with UVA and IR laser light for directional generation of a dermal collagen matrix

摘要

The present invention refers to a Laser therapy system and a method for skin treatment, comprising:
a unit for dispensing a Photosensitizer containing agent;a first light source which generates at least one first light with a first wavelength;a second light source as a Laser light source which generates at least a second light with a second wavelength;an optical system which is connected to the first and to the second light source, comprising an electromechanical displacement device with an optical deflection and focusing system such that the first and second light gets focused and a respective focus point can be controllably positioned in the skin; anda control unit for controlling the electromechanical displacement device and the first and the second light source such that the respective light spot with a controlled energy and position in the skin is produced.

1. A laser therapy system for skin treatment in a volume-like treatment region in a depth of the skin, comprising:
a) a photosensitizer-containing agent; b) a dispenser for applying the photosensitizer-containing agent on the skin; c) a first light source which generates at least one first light with a first wavelength in the ultraviolet A (UVA) range to mediate formation of collagen and elastin cross-linking in the treatment region in the presence of the photosensitizer containing agent when focused in the treatment region; d) a second light source including an infrared (IR) laser light source which generates at least one second light with a second wavelength to increase permeability of blood corpuscles in end arterioles in the treatment region; e) an optical system in communication with the first and the second light source and with which the at least one first and second light is taken up and focused in the treatment volume comprising an optical deflection and focusing system comprising an adapter plate said optical system is configured to deflect and focus through said adapter plate said first light to first focus points and said second light to second focus points into the treatment region, said first focus points are focused between and around respective papillae in said skin, said second focus points are focused at end arterioles within the respective papillae in said skin; f) an imaging system, said imaging system comprising means for recognizing said papillae and areas between the papillae and generating image data; and g) a control unit comprising a processor unit configured to receive image data from the said imaging system, to compute and assign xyz positions for the first focus points between and around papillae in said skin and the second focus points on end arterioles, and to control the optical system, the first light source and the second light source, such that said first focus points are focused between and around the papillae and said second focus points are focused at the end arterioles within the papillae.
