An apparatus for cutting a tissue part (10a) out of a tissue (10) by means of focused laser radiation exhibits the following: - a suction ring (28) which has a sealing surface (42) that is capable of being applied onto a surface (22) of the tissue (10), - devices (34, 36, 46) for generating an underpressure in a cavity (38) that is delimited by the sealing surface (42), by the surface (22) of the tissue (10) and by the suction ring, and - an applanation plate (30) that is capable of being pressed against the surface of the tissue (20) for the purpose of shaping, and - a body (40) that is opaque to the laser radiation, that interacts with the suction ring (28) and with its inner edge (40a) defines an edge (14) of the tissue part (10a).
L'invention concerne un dispositif de découpe d'un fragment de tissu (10a) dans un tissu (10) à l'aide d'un faisceau laser focalisé. Ce dispositif comprend : - un anneau aspirant (28) ayant une surface d'étanchéité (42) qui peut être appliquée sur la surface (22) du tissu (10), - des équipements (34, 36, 46) destinés à produire une dépression dans un espace vide (38) qui est délimité par la surface d'étanchéité (42), la surface (22) du tissu (10) et l'anneau d'aspiration, - une plaque d'aplatissement (30) qui peut être appliquée à la surface du tissu (10) pour lui donner une forme, et un corps opaque au rayonnement laser (40) qui coopère avec l'anneau d'aspiration (28) et définit par son bord intérieur (40a) un bord (14) du fragment de tissu (10a).
