Problems solved by technology

[0036] In view of these additional difficulties related to the distance from or adjacent to the area to be treated, virtually none of the laser devices in the prior art incorporate infrared sensors due to the significant inaccuracy of the measurements

Embodiment Construction

[0062] As the light source, a laser source or an LED source can be used, but a laser source is preferably used. The laser source emits in a wavelength range of 0.6 μm to 2.5 μm, preferably 0.7 μm to 2.2 μm, particularly preferably 1.1 μm to 1.6 μm, for example 1.21 μm. The light source allows 1 to 500J / cm 2 , preferably 2 to 250 J / cm 2 , particularly preferably 5 to 200 J / cm 2 Skin fluence is delivered to the treated skin surface.

[0063] In the case of the device according to the invention, the field of view of the infrared sensor is not therefore more divergent, but has a constriction (focal point) around which the diameter of the field of view is smallest. Therefore, a field of view with a diameter of 1.5mm to 8mm can be obtained practically at a distance of 10mm to 60mm from the sensor. It is thus possible to place the sensor away from the treatment area, thereby avoiding disturbances due to diffusion of the laser light. In fact, the intensity of light interference d...

Abstract

The invention relates to a mechanism for the use of light beams for dermatological treatments, comprising: a laser source (1) adapted to direct the laser beam to at least one area (2) within the area of ​​the skin to be treated; a non-contact measuring device, Sensitive to temperature-dependent radiation for measuring the skin area corresponding to the treated skin area (2); and means (13) for controlling said laser source by said measuring means, the device is characterized in that said non-contact The measuring device comprises an infrared sensor (4) and an objective lens (20) adapted to focus the field of view (5) of the infrared sensor such that the skin area contained in the field of view (5) is fully included in the skin area (2) treated by the device.

Description

technical field [0001] The present invention relates to a device for dermatological treatment using a laser beam preferably having a wavelength of 1.1 μm to 1.6 μm, for example 1.21 μm. Background technique [0002] From the document WO 2009 / 071592 it is known that there are devices for the perioperative and postoperative treatment of surgical trauma. The device uses a laser source with a wavelength of 0.6 μm to 2.5 μm that shapes its beam so that when the laser irradiates the skin, the distribution of energy over the area to be treated is uniform. More specifically, the beam is shaped into a rectangle to match the geometry of the incision, and the incision is then treated in segments equal in size to the length of the rectangle formed by the laser beam. [0003] The difficulty with this device lies in the fact that, for each segment, the power and exposure time of the laser must be determined in order to heat the edge of the cut to a certain temperature which must be preci...
