Title
(EN) SURGICAL LUMINAIRE
(FR) APPAREIL D'ECLAIRAGE CHIRURGICAL
Abstract
(EN)
A luminaire (10) used in a surgical field includes a pair of lenses (32, 34) positioned along an optical axis of the luminaire, for focusing a beam of light provided by a fiber optic (16). A mechanism (28) displacing the lenses with respect to one another to vary the spot sizes positioned adjacent to or apart from one another without rotating the optic fiber or the lenses. The luminaire also includes a reflecting mirror (36), positioned along the optical axis, for reflecting the beam of light into the surgical field, one or more filters (40) mounted to an exit aperture of the luminaire for filtering the beam of light, a plurality of linear polarizer (42, 44) mounted to an exit aperture (18) and to a surgical loupe respectively, and a fiber optic beam width reducer (58) reducing the beam width emitted from the fiber optic to a spot size beyond the spot size achieved by displacing the lenses.
(FR)
Un appareil d'éclairage (10) utilisé en chirurgie comprend une paire de lentilles (32, 34) placées le long d'un axe optique de l'appareil qui permettent de concentrer un faisceau lumineux généré par une fibre optique (16). Un mécanisme (28) déplaçant les lentilles l'une par rapport à l'autre fait varier le diamètre du point d'impact du faisceau, lorsque les lentilles sont placées l'une à côté de l'autre ou sont espacées l'une de l'autre, sans faire tourner la fibre optique ou les lentilles. L'appareil d'éclairage comporte également un miroir réfléchissant (36), positionné le long de l'axe optique, et conçu pour renvoyer le faisceau lumineux dans le champ opératoire. Au moins un filtre (40) est fixé sur un orifice de sortie de l'appareil d'éclairage pour filtrer le faisceau lumineux, une pluralité de polariseurs linéaires (42, 44) sont fixés respectivement sur un orifice de sortie (18) et sur une loupe chirurgicale, et un réducteur (58) de largeur du faisceau de fibre optique réduit la largeur du faisceau de fibre optique émis par la fibre optique pour obtenir une réduction du diamètre du point d'impact du faisceau plus importante que celle obtenue par le déplacement des lentilles.
