Title (EN) ENDOSSEOUS SCREWS AND ORTHOPAEDIC DEVICE TO ASSIST THE RIGID OSTEOSYNTHESIS OF FRACTURES
(FR) VIS ENDO-OSSEUSES ET DISPOSITIF ORTHOPÉDIQUE DESTINÉ À ASSISTER L'OSTÉOSYNTHÈSE RIGIDE DE FRACTURES
Abstract:
(EN) Endosseous screw (1) for fixing a plate (102) to a bone site (300), comprising an at least partially threaded shaft (2), insertion means for inserting the screw into a bone site and a distal portion (33) provided for engaging said plate to fasten it to said bone site and comprising a head (3) having facets (30) defining an external peripheral profile provided for engagement with a tubular manipulating wrench, to allow the screw (1) to be extracted from the bone site (300) into which it has been inserted, wherein the facets (30) are curvilinear and the external peripheral profile defined by same facets (30) has a convex barrel- like shape, in order to allow a stable coupling between the tubular manipulating wrench and said profile, which is maintained during the untightening phase of screw from plate, even when said tubular manipulating wrench is oriented in an inclined direction with respect to a longitudinal axis (x) of the endosseous screw (1).
(FR) L'invention concerne une vis endo-osseuse (1) destinée à fixer une plaque (102) sur un site osseux (300), qui comprend un arbre au moins partiellement fileté (2), des moyens d'insertion destinés à insérer la vis dans un site osseux et une partie distale (33) prévue pour s'engager avec ladite plaque afin de l'attacher audit site osseux et qui comprend une tête (3) comprenant des facettes (30) qui définissent un profil périphérique externe prévu pour s'engager avec une clé tubulaire de manipulation, afin de permettre l'extraction de la vis (1) du site osseux (300) dans lequel elle a été insérée. Selon l'invention, les facettes (30) sont curvilignes et le profil périphérique externe défini par ces mêmes facettes (30) a une forme cylindrique convexe, afin de permettre un couplage stable entre la clé tubulaire de manipulation et ledit profil, qui est maintenu pendant la phase de desserrage de la vis de la plaque, même lorsque ladite clé tubulaire de manipulation est orientée dans une direction inclinée par rapport à un axe longitudinal (x) de la vis endo-osseuse (1).
