ABSTRACT:
The invention relates to a process of treatment in the field of dermatology, for the treatment of cutaneous angio dysplasias, using the energy emitted by a laser source, as well as to an apparatus for the treatment of skin angiomas implementing the process. The apparatus includes a laser source suitable for supplying laser radiation, a treatment instrument for receiving the laser radiation from the source and whereby a plurality of consecutive laser shots is effected to form a plurality of resulting impacts on the area of the body to be treated. Following each shot, the area of the body thus treated has, at the resulting impact, at least a given relaxation time. The apparatus includes a support frame, an optical fiber disposed in the frame. The optical fiber has two ends, the first of the ends being suitable for connection to the laser source via the connecting means, the second end being mobile and suitable for generating a displaceable laser spot. An automatic control unit with memory controls in time and space sequential scanning of the second end of the optical fiber, and permits a sequence of consecutive laser shots such that two consecutive laser shots form two resulting impacts, which are not contiguous, if the time lapse between the two consecutive laser shots is less than the given thermal relaxation time, and the impacts of the different consecutive laser shots completely cover the surface through the contiguous juxtaposition of the different impacts resulting from the different laser shots.
