Abstract

La présente invention concerne une vis pour un implant et, plus particulièrement, une vis pour un implant pouvant empêcher que la vis ne se dévisse, qui maintient la fixation d'un élément de fixation et d'une butée, maintenant ainsi un état de fixation stable. Une vis pour un implant selon la présente invention comprend une partie vis et une partie tête. La partie tête présente une pluralité de cavités formées sur la surface périphérique extérieure, qui est insérée dans une butée et entre en contact avec celle-ci, selon la direction circonférentielle, se couplant ainsi à la butée située sur l'extrémité supérieure d'un élément de fixation. Et la partie tête est formée pour avoir un diamètre qui diminue en allant de sa partie supérieure vers sa partie inférieure. Selon la présente invention, des cavités sont formées sur la surface périphérique extérieure selon la direction circonférentielle de telle sorte que, pendant un couplage de vis, la surface inférieure de la vis, qui est couplée à une butée, est déformée vers les cavités. La surface inférieure déformée applique ensuite une force sur la butée de telle sorte qu'un couplage de vis entre la vis et l'élément de fixation ne se dévisse pas. Et, étant donné que le diamètre diminue de la partie supérieure vers la partie inférieure, et qu'au moins une pluralité de cavités sont formées, un contact de surface latérale au niveau de chaque partie cavité entraîne une déformation, augmentant ainsi la force du couplage de vis entre la vis et l'élément de fixation. De plus, selon la présente invention, le côté extérieur de la surface inférieure de la partie tête est formé pour faire davantage saillie que son côté intérieur, de telle sorte qu'une déformation de la partie tête est plus grande au niveau de la partie de contact avec la butée, empêchant ainsi le détachement du couplage de la vis et de l'élément de fixation.
