Abstract

L’invention concerne un implant (1) orthopédique comprenant au moins une première partie (2) et une deuxième partie (3) destinées à être assemblées entre elles par l’intermédiaire d’une vis (4) de serrage traversant un premier orifice (21) débouchant ménagé au travers de la première partie (2) et venant en prise dans un deuxième orifice (31) ménagé dans la deuxième partie (3). Selon l’invention, la vis (4) de serrage comprend : - une première extrémité (41) pourvue d’un filet orienté selon un premier sens coopérant avec un taraudage ménagé dans le premier orifice (21) et orienté dans le même premier sens ; - une deuxième extrémité (42) pourvue d’un filet orienté selon un deuxième sens inverse coopérant avec un taraudage ménagé dans le deuxième orifice (31) et orienté dans le même deuxième sens inverse ; de sorte que la rotation de la vis (4) dans le deuxième sens permet le rapprochement de la première partie (2) et de la deuxième partie (3) pour leur assemblage, et la rotation de la vis (4) dans le premier sens permet l’éloignement de la première partie (2) et de la deuxième partie (3) pour leur désassemblage. Figure pour l’abrégé : Fig. 4The invention relates to an orthopedic implant (1) comprising at least a first part (2) and a second part (3) intended to be assembled together by means of a clamping screw (4) passing through a first orifice ( 21) emerging through the first part (2) and engaging in a second orifice (31) formed in the second part (3). According to the invention, the clamping screw (4) comprises: - a first end (41) provided with a thread oriented in a first direction cooperating with a thread formed in the first orifice (21) and oriented in the same first direction ; - a second end (42) provided with a thread oriented in a second opposite direction cooperating with a thread formed in the second orifice (31) and oriented in the same second opposite direction; so that the rotation of the screw (4) in the second direction allows the approximation of the first part (2) and the second part (3) for their assembly, and the rotation of the screw (4) in the first direction allows the removal of the first part (2) and the second part (3) for their disassembly.
