INSTRUMENTATION RACHIDIENNE A TIGE ORIENTABLE
La présente invention a trait à une instrumentation rachidienne à tige orientable et vise plus particulièrement un perfectionnement aux instrumentations du type décrit dans FR
A-2.657.775.SPINAL INSTRUMENTATION WITH ADJUSTABLE ROD
The present invention relates to spinal instrumentation with an adjustable rod and is more particularly aimed at improving instrumentation of the type described in FR
A-2,657,775.
Dans le brevet français FR-A-2.657.775 est décrit notamment une instrumentation rachidienne à tige destinée à réduire et contenir le rachis, comprenant plusieurs vis pédiculaires à tête cylindrique filetée recevant une pièce s'encastrant dans le corps de la vis et dans laquelle est reçue une tige de solidarisation bloquée entre ladite pièce et la partie conique d'un écrou de blocage engagé sur la tête de la vis. In French patent FR-A-2,657,775 is described in particular a spinal instrumentation with rod intended to reduce and contain the spine, comprising several pedicle screws with threaded cylindrical head receiving a part fitting into the body of the screw and in which is received a securing rod blocked between said part and the conical part of a locking nut engaged on the head of the screw.
Ce système permet de bloquer la tige par rapport aux vis, mais la tige se trouve dans une position par rapport à la vis, à savoir orthogonal à la vis, qui est la même pour toutes les vis et ne peut être modifiée. This system makes it possible to block the rod relative to the screws, but the rod is in a position relative to the screw, namely orthogonal to the screw, which is the same for all the screws and cannot be modified.
Le but de la présente invention est précisément de proposer un agencement de fixation de la tige par rapport à la vis permettant de régler à volonté l'angle forme par les axes respectifs de la tige et de la vis et de bloquer dans cette position la tige sur la vis. The object of the present invention is precisely to propose an arrangement for fixing the rod relative to the screw allowing the angle formed by the respective axes of the rod and the screw to be adjusted as desired and the rod to be locked in this position. on the screw.
A cet effet, l'invention a pour objet une instrumentation rachidienne à tige orientable, comprenant des vis pédiculaires à tête filetée séparée de la pointe de la vis par un corps intermédiaire permettant le vissage, une pièce de réception blocage d'une tige de solidarisation présentant un trou pour son enfilement sur ladite tête filetée et munie d'un logement pour recevoir la tige latéralement à la vis et un écrou reçu sur la tête filetée et muni d'une face inférieure tronconique susceptible de venir en contact avec la tige et la verrouiller, caractérisée en ce que
- le trou de ladite pièce de réception-blocage est oblong dans une direction parallèle à l'axe de la tige et la face inférieure de la pièce est en contact avec ledit corps intermédiaire par des portées sphériques, en sorte que ladite pièce peut pivoter de manière à déplacer la tige dans un plan parallèle à l'axe de la vis et contenant l'axe de la tige,
- et en ce que ladite face inférieure tronconique de l'écrou vient en contact, en une zone opposée à la zone de contact avec la tige, avec une surface tronconique correspondante ménagée sur ladite pièce de réception-blocage.To this end, the subject of the invention is spinal instrumentation with an adjustable rod, comprising pedicle screws with threaded head separated from the point of the screw by an intermediate body allowing the screwing, a receiving part blocking a fixing rod. having a hole for its threading on said threaded head and provided with a housing for receiving the rod laterally to the screw and a nut received on the threaded head and provided with a frustoconical underside capable of coming into contact with the rod and the lock, characterized in that
the hole of said receiving-blocking piece is oblong in a direction parallel to the axis of the rod and the underside of the piece is in contact with said intermediate body by spherical bearings, so that said piece can pivot by so as to move the rod in a plane parallel to the axis of the screw and containing the axis of the rod,
- And in that said frustoconical lower face of the nut comes into contact, in a zone opposite to the zone of contact with the rod, with a corresponding frustoconical surface formed on said receiving-blocking part.
Avec un tel dispositif, lorsque la tige de solidarisation est en place dans son logement récepteur, son angulation par rapport à l'axe de la vis pédiculaire peut être ajustée à volonté et bloquée à la valeur choisie, par pivotement de la tige dans un plan contenant son axe et parallèle à l'axe de la vis, puis serrage de l'écrou de blocage. Ce pivotement, qui s'effectue autour du centre des portées sphériques ménagées entre la pièce réceptrice de la tige et le corps intermédiaire de la vis, permet de donner à la tige une inclinaison de quelques degrés, pouvant atteindre et dépasser 150 par exemple, par rapport à la position habituelle, immuable, des dispositifs antérieurs, orthogonalement à l'axe de la vis pédiculaire. With such a device, when the securing rod is in place in its receiving housing, its angulation relative to the axis of the pedicle screw can be adjusted at will and locked at the selected value, by pivoting the rod in a plane containing its axis and parallel to the axis of the screw, then tightening the locking nut. This pivoting, which takes place around the center of the spherical bearing surfaces formed between the receiving part of the rod and the intermediate body of the screw, makes it possible to give the rod an inclination of a few degrees, which can reach and exceed 150 for example, by relative to the usual, immutable position of the anterior devices, orthogonally to the axis of the pedicle screw.

Sur la figure 1 on a représenté en 1 une vis pédiculaire comprenant une partie inférieure ou pointe filetée 2, destinée à pénétrer dans le corps vertébral, et une partie supérieure 3 également filetée, séparées par un corps intermédiaire 4 permettant le vissage de la vis 1 et de forme hexagonale dans le mode de réalisation illustré. In Figure 1 is shown in 1 a pedicle screw comprising a lower part or threaded tip 2, intended to penetrate into the vertebral body, and an upper part 3 also threaded, separated by an intermediate body 4 allowing the screw 1 to be screwed and hexagonal in the illustrated embodiment.
La partie supérieure filetée 3 est séparée du corps 4 par une partie lisse 5 dont le diamètre correspond par exemple au diamètre à fond de filet de la partie 3 et qui est elle-même raccordée au corps hexagonal 4 par une surface sphérique 6. The threaded upper part 3 is separated from the body 4 by a smooth part 5 whose diameter corresponds for example to the thread-bottom diameter of the part 3 and which is itself connected to the hexagonal body 4 by a spherical surface 6.
En 7 est représentée une pièce de réception-blocage d'une tige de solidarisation conventionnelle 8, cylindrique et à surface lisse, et en 9 un écrou de blocage de la tige 8 sur la pièce 7, susceptible d'être vissé sur la partie filetée 3 de la vis 1. L'écrou 9 est de forme hexagonale et présente une face inférieure tronconique 10 à la manière connue. In 7 is shown a reception-blocking part of a conventional securing rod 8, cylindrical and with a smooth surface, and in 9 a rod blocking nut 8 on the part 7, capable of being screwed onto the threaded part. 3 of the screw 1. The nut 9 is hexagonal in shape and has a frustoconical underside 10 in the known manner.
La pièce 7 est constituée d'une plaquette 11 percée d'un trou 12 pour l'engagement libre de la partie filetée 3
La face inférieure de la plaquette 11 est munie, au niveau du trou 12, d'un lamage 13 définissant deux ressauts 14 en regard dont l'écartement correspond sensiblement au diamètre (entre faces) du corps hexagonal 4. The part 7 consists of a plate 11 pierced with a hole 12 for the free engagement of the threaded part 3
The lower face of the plate 11 is provided, at the level of the hole 12, with a countersink 13 defining two opposite projections 14 whose spacing corresponds substantially to the diameter (between faces) of the hexagonal body 4.
Le trou 12 est de section oblongue avec un grand axe 15 (figure 4) parallèle à la tige 8 en position sur la pièce 7 (figure 5). The hole 12 is of oblong section with a large axis 15 (Figure 4) parallel to the rod 8 in position on the part 7 (Figure 5).
Le bord du trou 12, côté lamage 13, est chanfreiné suivant une surface sphérique 16 de même courbure que la surface 6 du corps 4. The edge of the hole 12, counterbore side 13, is chamfered along a spherical surface 16 of the same curvature as the surface 6 of the body 4.
La plaquette 11 est prolongée d'un côté par une partie incurvée 17 définissant sur sa face supérieure, à la manière connue, un logement cylindrique 18 d'axe parallèle à l'axe 15, de réception de la tige 8. The plate 11 is extended on one side by a curved part 17 defining on its upper face, in the known manner, a cylindrical housing 18 with an axis parallel to the axis 15, for receiving the rod 8.
La plaquette 11 est prolongée, du côté opposé au logement 18, par un bossage 19 servant d'appui à l'écrou de blocage 9. The plate 11 is extended, on the side opposite to the housing 18, by a boss 19 serving to support the locking nut 9.
Ce bossage 9 définit une surface cylindrique 20 dont les génératrices sont orthogonales à l'axe du trou 12 et dont l'axe passe par le centre de courbure 21 (figure 3) de la surface sphérique 16, ledit centre 21 étant par ailleurs situé sur l'axe 12a du trou 12. Par ailleurs, le bord intérieur du bossage 19 est chanfreiné suivant une surface tronconique 22 correspondant à la face tronconique 10 de l'écrou 9. La surface tronconique 22 est centrée sur un axe perpendiculaire à l'axe du trou 12 et l'angle au sommet du cône engendrant la surface 22 est complémentaire de l'angle au sommet du cône engendrant la surface 10.This boss 9 defines a cylindrical surface 20 whose generatrices are orthogonal to the axis of the hole 12 and whose axis passes through the center of curvature 21 (FIG. 3) of the spherical surface 16, said center 21 being moreover located on the axis 12a of the hole 12. Furthermore, the internal edge of the boss 19 is chamfered along a frustoconical surface 22 corresponding to the frustoconical face 10 of the nut 9. The frustoconical surface 22 is centered on an axis perpendicular to the axis of the hole 12 and the angle at the top of the cone generating the surface 22 is complementary to the angle at the top of the cone generating the surface 10.
La figure 5 illustre le dispositif de l'invention en position montée, l'écrou 9 n'étant pas encore serré. Dans cette position, la pièce 7 est calée en rotation autour de la vis 1 par le lamage (13,14) qui vient s'enfourcher sur l'extrémité du corps hexagonal 4. La tige 8 est reçue dans le logement 18 avec son axe orthogonal à l'axe du trou 12 et les surfaces sphériques 16 et 6 sont en contact. FIG. 5 illustrates the device of the invention in the mounted position, the nut 9 not yet being tightened. In this position, the part 7 is locked in rotation around the screw 1 by the counterbore (13,14) which straddles the end of the hexagonal body 4. The rod 8 is received in the housing 18 with its axis orthogonal to the axis of the hole 12 and the spherical surfaces 16 and 6 are in contact.
En serrant l'écrou 9, la face tronconique 10 va venir en contact, d'un côté, avec la tige 8 et, du côte opposé, avec la surface tronconique 22. By tightening the nut 9, the frustoconical face 10 will come into contact, on one side, with the rod 8 and, on the opposite side, with the frustoconical surface 22.
Avant le serrage on peut donner à la tige 8 une angulation a (figure 6) par rapport à une ligne 23 orthogonale à l'axe 24 de la vis pédiculaire 1, de l'ordre de quelques degrés, de part ou d'autre de la ligne 23, l'angulation a pouvant atteindre et dépasser par exemple une quinzaine de degrés. Before tightening, the rod 8 can be given an angulation a (FIG. 6) relative to a line 23 orthogonal to the axis 24 of the pedicle screw 1, of the order of a few degrees, on either side of line 23, the angulation a being able to reach and exceed for example about fifteen degrees.
L'inclinaison de la tige 8 se fait par rotation de la pièce 7 sur le corps 4 (figure 7) grâce aux portées sphériques (6,16) entre ces deux organes et au trou oblong 12 dans lequel la partie 5 peut avoir angulairement un certain débattement. The inclination of the rod 8 is effected by rotation of the part 7 on the body 4 (FIG. 7) thanks to the spherical bearings (6.16) between these two members and to the oblong hole 12 in which the part 5 can have an angular some travel.
En serrant l'écrou 9, la face tronconique 10 vient en contact avec la surface tronconique 22 le long d'un segment 25 de génératrice qui demeure constamment dans un plan perpendiculaire au plan de débattement de la tige 8 et contenant l'axe 24 de la tige 8, quelle que soit l'angulation a de la tige 8 dans le plan de débattement, ce qui assure une bonne stabilité du blocage de la tige 8 dans sa position.By tightening the nut 9, the frustoconical face 10 comes into contact with the frustoconical surface 22 along a segment 25 of a generator which remains constantly in a plane perpendicular to the plane of movement of the rod 8 and containing the axis 24 of the rod 8, whatever the angulation a of the rod 8 in the deflection plane, which ensures good stability of the blocking of the rod 8 in its position.
L'écrou 9 représenté sur la figure 7 est muni, en outre, d'un frein 26 délimité par une entaille 27 ménagée orthogonalement à l'axe de l'écrou, au voisinage de l'extrémité supérieure de l'écrou. Ledit frein 26, une fois l'écrou 9 serré et bloqué, est déformé pour éviter tout desserrage ultérieur intempestif de l'écrou. The nut 9 shown in Figure 7 is further provided with a brake 26 defined by a notch 27 formed orthogonally to the axis of the nut, in the vicinity of the upper end of the nut. Said brake 26, once the nut 9 is tightened and locked, is deformed to avoid any untimely subsequent loosening of the nut.
Enfin, l'invention n'est évidemment pas limitée au mode de réalisation représenté et décrit ci-dessus mais en couvre au contraire toutes les variantes, notamment en ce qui concerne la forme de la pièce 7, de la partie 17-18 de réception de la tige 8, du bossage 19 d'appui de l'écrou 9 et les forme et agencement des surfaces 10,22 de contact entre l'écrou 9 et la pièce 7. Finally, the invention is obviously not limited to the embodiment shown and described above but on the contrary covers all the variants thereof, in particular as regards the shape of the part 7, of the receiving part 17-18 of the rod 8, of the boss 19 for supporting the nut 9 and the shape and arrangement of the surfaces 10, 22 of contact between the nut 9 and the part 7.
