摘要: A system of additive-manufacturing by laser melting of a powder bed. The system includes a first laser unit selectively emitting a first laser beam to form at least one layer of material by melting the powder bed; a second laser unit selectively emitting a second laser beam to machine at least a portion of the layer of material; and an optical unit enabling to focus the first laser beam on the powder bed to be melted and the second laser beam on the layer of material to be machined. The system is able to produce a part by successive stacking of melted then machined layers of material. A process of additive-manufacturing by laser melting of a powder bed is also contemplated.

摘要: The present invention relates to a device for holding human or animal corneal tissue previously removed for photon treatment thereof with electromagnetic radiation, notable in that the holding device comprises: a stack of elements along a longitudinal axis (A-A′) of the device, said stack comprising: a first plate (1) that is transparent to the electromagnetic radiation, a peripheral seal (4) positioned on the first plate (1), the peripheral seal (4) being intended to extend around the corneal tissue (6), a second plate (2) that is transparent to the electromagnetic radiation on the peripheral seal (4), an immobilizing system (51, 52) for immobilizing the stack of elements and able to press the first and second plates (1, 2) firmly against the corneal tissue in order to apply mechanical stress to the anterior and posterior faces of the corneal tissue.

摘要: The invention concerns a cutting process for producing a plurality of implants from a previously removed human or animal cornea, wherein the process comprises the following steps: depositing (200) the cornea in a holding device, cutting (300), using a laser source, the cornea contained in the holding device to obtain a cut cornea, detaching (400) each implant from the cut cornea, decellularizing (500) each detached implant to obtain decellularized implants, lyophilizing (600) each decellularized implant to obtain lyophilized implants, sterilizing (700) each lyophilized implant to obtain sterilized implants, packaging (800) each sterilized implant to obtain packaged implants.
