Title (DE) KNOCHENPLATTE
(EN) BONE PLATE
(FR) PLAQUE POUR LIAISON OSSEUSE
Abstract:
(DE) Die Knochenplatte (1) besitzt mehrere sich zur Knochenkontaktfläche (2) hin verjüngende konische Plattenlöcher (3) und zwei zur Verankerung der Knochenplatte (1) bestimmte Knochenschrauben (4). Die Knochenschrauben (4) sind mit einem zur Einführung in die konischen Plattenlöcher (3) bestimmten, darauf abgestimmten, konischen Kopfteil (5) mit strukturierter Mantelfläche und einem zur Verankerung im Knochen bestimmten Gewindeteil (6) versehen. Die strukturierte Mantelfläche weist eine höhere Härte als das Material der Knochenplatte (1) im Bereich ihrer Plattenlöcher (3) auf.
(EN) The bone plate (1) proposed has several conical holes which taper towards the surface (2) in contact with the bone and two screws (4) designed to anchor the plate (1) in place. Each of the screws (4) has a conical head (5), with a patterned curved surface, shaped to fit into the conical holes (3) in the plate, plus a threaded shank (6) designed to anchor the screw in the bone. The patterned curved surface of the screw head is harder than the material of which the plate (1) is made in the vicinity of the holes (3).
(FR) L'invention concerne une plaque (1) pour liaison osseuse, qui possède plusieurs trous (3) coniques se rétrécissant en direction de la surface de contact (2) des os et deux vis (4) destinées à l'ancrage de la plaque. Les vis (4) sont constituées d'une tête conique (5) conçue pour être introduite dans les trous coniques (3) de la plaque, la tête ayant une forme adaptée et une surface latérale structurée, et d'une partie filetée (6) destinée à l'ancrage dans l'os. La surface latérale structurée a une dureté supérieure à celle du matériau de la plaque (1) dans la zone de ses trous (3).
