Description Description
La présente invention concerne une tige d'instrument chirurgical de coupe rotatif notamment foret, mèche, taraud, fraise, comprenant une embase agencée pour l'accouplement de l'instrument à un dispositif d'entraînement. The present invention relates to a rotary cutter surgical instrument rod, in particular drill, drill bit, tap, cutter, comprising a base arranged for coupling the instrument to a drive device.
Lors d'interventions chirurgicales, divers instruments de coupe rotatifs tels que mèche, taraud, foret, fraise, sont utilisés et doivent être accouplés à un dispositif d'entraînement en rotation. During surgical procedures, various rotary cutting instruments such as drill bits, taps, drills, cutters, are used and must be coupled to a rotary drive.
Pour une grande partie des dispositifs connus, la tige comprend une embase présentant une forme permettant l'accouplement avec le mandrin, embout, raccord ou autres éléments similaires du dispositif d'entrainement en rotation. Parmi les embases que l'on rencontre le plus souvent pour de tels instruments (mèche, fraise, foret, taraud, ...) il y a celles qui présentent une section triangulaire perpendiculairement à l'axe de rotation, c'est-à-dire que l'embase présente une surface latérale prismatique, formée de trois plans parallèles à l'axe de rotation. Souvent l'embase au départ a une forme cylindrique et les trois faces planes formées par fraisage n'ont pas d'arête commune droite mais le raccord entre les faces planes est cylindrique. For a large part of the known devices, the rod comprises a base having a shape allowing the coupling with the mandrel, end piece, fitting or other similar elements of the rotary drive device. Among the bases that are most often encountered for such instruments (drill bit, drill, drill, tap, ...) there are those which have a triangular section perpendicular to the axis of rotation, that is to say -to say that the base has a prismatic lateral surface, formed of three planes parallel to the axis of rotation. Often the base at the start has a cylindrical shape and the three flat faces formed by milling have no common straight edge but the connection between the flat faces is cylindrical.
Une autre embase que l'on rencontre très souvent a une forme cylindrique et présente une seule face plane s'étendant uniquement sur une partie de l'embase cylindrique et le plan de la face est plus près de l'axe de la tige, c'est-à-dire que la section perpendiculairement à l'axe de la tige et légèrement supérieure à un demi-cercle. Another base which is very often encountered has a cylindrical shape and has a single flat face extending only over part of the cylindrical base and the plane of the face is closer to the axis of the rod, c that is to say that the section perpendicular to the axis of the rod and slightly greater than a semicircle.
Les fabricants de ces instruments rotatifs sont obligés d'avoir des doubles stocks du même outil mais avec une embase différente en fonction du type d'accouplement de l'utilisateur final. Cette obligation est coûteuse pour le fabricant aussi bien au point de vue fabrication que stockage. The manufacturers of these rotary instruments are obliged to have double stocks of the same tool but with a different base depending on the type of coupling of the end user. This obligation is costly for the manufacturer both from the manufacturing and storage point of view.
Ceci est vrai également pour les utilisateurs, tels que les hôpitaux et les cabinets médicaux, lesquels, en raison des appareils d'entraînement utilisés qui peuvent être de types différents, sont obligés d'acheter des mèches, forets, fraises, ... avec les deux types d'embases d'accouplement pour pouvoir utiliser leurs appareils. This is also true for users, such as hospitals and medical offices, who, because of the training devices used which may be of different types, are forced to buy bits, drills, cutters, ... with the two types of coupling bases to be able to use their devices.
La présente invention a pour but de proposer une tige d'instrument de coupe rotatif dont l'embase peut être accouplée indifféremment avec des dispositifs d'entraînement acceptant soit des embases dont la section perpendiculairement à l'axe de la tige est triangulaire, soit celles dont la section présente un demi cercle. The object of the present invention is to propose a rod for a rotary cutting instrument, the base of which can be coupled either with drive devices accepting either bases the section of which is perpendicular to the axis of the rod is triangular, or those whose section has a semi-circle.
La tige selon l'invention est caractérisée par le fait que ladite embase est formée de trois faces planes parallèles à l'axe de rotation dont l'une présente en un point intermédiaire de sa dimension parallèle à l'axe de rotation un décrochement formant entre ledit point et l'extrémité libre de l'embase une face plane plus proche dudit axe que le reste de la face plane. The rod according to the invention is characterized in that said base is formed of three plane faces parallel to the axis of rotation, one of which has an offset at an intermediate point of its dimension parallel to the axis of rotation forming said point and the free end of the base have a flat face closer to said axis than the rest of the flat face.
L'avantage d'une tige avec une telle embase est donc qu'elle peut être indifféremment utilisée avec un dispositif d'accouplement destiné à recevoir des tiges avec embases dont la section perpendiculairement à l'axe de la tige a une forme triangulaire, de préférence un triangle équilatéral, ou avec un dispositif d'accouplement destiné à recevoir des tiges présentant une embase dont la section perpendiculairement à l'axe de la tige a une forme approximativement demi-circulaire. The advantage of a rod with such a base is therefore that it can be indifferently used with a coupling device intended to receive rods with bases whose section perpendicular to the axis of the rod has a triangular shape, of preferably an equilateral triangle, or with a coupling device intended to receive rods having a base whose section perpendicular to the axis of the rod has an approximately semicircular shape.
Selon une exécution préférée de l'invention, l'embase a au départ une forme cylindrique et les plans des trois faces se coupent au-delà de la surface latérale du cylindre de sorte que la surface latérale de l'embase présente alternativement des faces planes et des parties cylindriques. According to a preferred embodiment of the invention, the base has a cylindrical shape at the start and the planes of the three faces intersect beyond the lateral surface of the cylinder so that the lateral surface of the base alternately has planar faces. and cylindrical parts.
Selon une exécution préférée l'embase présente également une gorge périphérique permettant d'assurer axialement la tige. According to a preferred embodiment, the base also has a peripheral groove making it possible to secure the rod axially.
L'invention sera décrite plus en détail à l'aide du dessin annexé. The invention will be described in more detail using the attached drawing.
La fig. 1 est une vue de côté d'une tige selon l'invention. Fig. 1 is a side view of a rod according to the invention.
La fig. 2 est une vue de la même tige tournée autour de son axe de 90°. Fig. 2 is a view of the same rod turned around its 90 ° axis.
Les fig. 3 et 4 sont des coupes selon les lignes III-III et IV-IV de la fig. 1. Figs. 3 and 4 are sections along lines III-III and IV-IV of FIG. 1.
Dans l'exemple qui suit, nous avons décrit une mèche dont la tige est munie d'une embase selon l'invention, néanmoins ceci peut être appliqué de la même manière à tout instrument rotatif tels que foret, fraise, taraud, ... In the example which follows, we have described a drill bit whose rod is provided with a base according to the invention, nevertheless this can be applied in the same way to any rotary instrument such as drill, milling cutter, tap, ...
La mèche M comprend donc une tige 1 présentant une embase de préférence cylindrique 2 formée de trois faces 4, 5, 6 planes disposées symétriquement par rapport à l'axe A de la tige 1. L'une des faces et notamment la face 4 présente, en un point approximativement au milieu de sa longeur, un décrochement 3 formant une face 4a qui se trouve plus près de l'axe A de la tige. The wick M therefore comprises a rod 1 having a preferably cylindrical base 2 formed by three faces 4, 5, 6 planes arranged symmetrically with respect to the axis A of the rod 1. One of the faces and in particular the face 4 has , at a point approximately in the middle of its length, a recess 3 forming a face 4a which is closer to the axis A of the rod.
De préférence les trois faces planes 4, 5 et 6 ne forment pas d'arête rectiligne mais les raccords sont les parties des cylindres 7, 8, 9 restant après avoir coupé le cylindre par les plans contenant les faces 4, 5, 6. La face plane 4a bien qu'étant plus près de l'axe A de la tige 1 est raccordée au reste des deux autres faces également par deux surfaces cylindriques. Preferably the three flat faces 4, 5 and 6 do not form a straight edge but the connections are the parts of the cylinders 7, 8, 9 remaining after having cut the cylinder by the planes containing the faces 4, 5, 6. The flat face 4a although being closer to the axis A of the rod 1 is connected to the rest of the other two faces also by two cylindrical surfaces.
Selon une variante d'exécution on peut prévoir une gorge 10 permettant de maintenir axialement l'instrument. According to an alternative embodiment, it is possible to provide a groove 10 making it possible to maintain the instrument axially.
Bien que cette invention est avant tout destinée à l'accouplement de mèche, foret, fraise, taraud chirurgicaux, elle n'est pas limitée à ce type d'instrument et peut être également utilisée en mécanique. Although this invention is primarily intended for the coupling of drill bits, drills, cutters, surgical taps, it is not limited to this type of instrument and can also be used in mechanics.
