Abstract

Ensemble d'un élément de fixation fileté et de son outil d'entraînement. Un outil analogue à un tournevis peut s'engager dans l'extrémité d'une vis ou d'un autre type d'élément de fixation. L'outil et l'élément sont agencés de façon que, lorsqu'ils sont en prise et utilisés, ils ne risquent pas de se dégager par inadvertance. Dans ce but, la tête de l'élément de fixation comprend deux fentes perpendiculaires et la lame du tournevis comprend à son extrémité un ergot disposé dans le sens de sa largeur. La lame et l'ergot s'engagent dans les fentes de façon à verrouiller le tournevis et l'élément de fixation qui, cependant, peuvent être séparés. Application à la chirurgie osseuse pour la mise en place de vis de jonction.Set of a threaded fastener and its driving tool. A screwdriver-like tool can engage the end of a screw or other type of fastener. The tool and element are so arranged that when engaged and in use there is no risk of inadvertent release. For this purpose, the head of the fastening element comprises two perpendicular slots and the blade of the screwdriver comprises at its end a lug arranged in the direction of its width. The blade and the lug engage in the slots so as to lock the screwdriver and the fastener which, however, can be separated. Application to bone surgery for the placement of junction screws.
