Description

L'invention concerne une plaque-agrafe pour ostéosynthèse.The invention relates to a staple plate for osteosynthesis.

II est connu, en chirurgie osseuse, d'utiliser des plaques et vis ainsi que des lames-plaques pour maintenir des fragments osseux l'un contre l'autre, de façon stable, afin d'obtenir une sollicitation osseuse optimale pour l'ostéogenèse et la consolidation. Des lames-plaques sont utilisées principalement dans le domaine des ostéotomies tibiales. It is known, in bone surgery, to use plates and screws as well as plate blades to hold bone fragments against each other, in a stable manner, in order to obtain optimal bone stress for osteogenesis. and consolidation. Plate slides are used mainly in the field of tibial osteotomies.

Dans le domaine rachidien et tout particulièrement dans le domaine du rachis cervical, il est souvent nécessaire de stabiliser deux vertèbres adjacentes en compression ou en distraction ou de maintenir l'un contre l'autre des fragments de vertèbre pour faciliter l'ostéogenèse et la consolidation. Il est souvent utilisé, pour cela, des implants à vis dont les têtes sont reliées par des tiges ou des plaques. Toutefois, de tels moyens, bien que donnant satisfaction en chirurgie rachidienne, peuvent être considérés comme contraignants et surdimensionnés dans leur application aux vertèbres cervicales.In the spinal area and especially in the area of the cervical spine, it is often necessary to stabilize two adjacent vertebrae in compression or distraction or to hold fragments of the vertebrae against each other to facilitate osteogenesis and consolidation . Screw implants are often used for this, the heads of which are connected by rods or plates. However, such means, although satisfactory in spinal surgery, can be considered restrictive and oversized in their application to the cervical vertebrae.

La présente invention a pour but de remédier à ces inconvénients.The object of the present invention is to remedy these drawbacks.

Cette invention, telle qu'elle se caractérise, résout ie problème consistant à créer une plaque-agrafe avec laquelle, d'une part, les vertèbres ou les morceaux de vertèbres puissent être parfaitement stabilisés dans une position idéale en rapport avec les effets recherchés, et d'autre part, une bonne rigidité longitudinale puisse être obtenue malgré la faible épaisseur de la plaque et les sollicitations auxquelles sont soumises les vertèbres dans cette partie du rachis. This invention, as it is characterized, solves the problem of creating a staple plate with which, on the one hand, the vertebrae or the pieces of vertebrae can be perfectly stabilized in an ideal position in relation to the desired effects, and on the other hand, good longitudinal rigidity can be obtained despite the small thickness of the plate and the stresses to which the vertebrae are subjected in this part of the spine.

La plaque-agrafe pour ostéosynthèse réalisée d'une seule pièce, constituée d'une plaque munie de plusieurs picots et de deux trous de passage des vis de fixation selon l'invention se caractérise principalement en ce que la plaque est galbée transversalement et comporte quatre picots ou plus répartis symétriquement deux par deux à chaque extrémité ou/et le long de la plaque, au niveau ou entre les trous de passage des vis de fixation, lesquels sont oblongs dans le sens longitudinal de la plaque, laquelle comporte, en son milieu, un orifice fileté de fixation d'un positionneur-impacteur ces trous pouvant etre remplacés par une fixation de chaque côté de la plaque.The staple plate for osteosynthesis produced in one piece, consisting of a plate provided with several pins and two holes for the fixing screws according to the invention is mainly characterized in that the plate is curved transversely and has four pins or more distributed symmetrically two by two at each end and / or along the plate, at or between the holes for the fixing screws, which are oblong in the longitudinal direction of the plate, which has, in its middle , a threaded orifice for fixing a positioner-impactor these holes can be replaced by a fixing on each side of the plate.

Les picots comportent latéralement et symétriquement des dents d'ancrage.The pins have laterally and symmetrically anchoring teeth.

Toutes les formes extérieures d'ancrage de ces picots peuvent être utilisées. Toutefois, nous avons pensé que la forme harpon était la meilleure.All the external forms of anchoring of these pins can be used. However, we thought the harpoon shape was the best.

Les picots sont reliés à la plaque par des parties courbes raccordées au galbe de ladite plaque.The pins are connected to the plate by curved parts connected to the curve of said plate.

La plaque-agrafe est réalisée préférentiellement par découpagepliage à froid dans une bande métallique en acier ou en titane
Emboutissage. Coupe au fil, à l'eau ou usinage.The staple plate is preferably produced by cutting and cold folding from a metallic strip of steel or titanium
Stamping. Cut with wire, water or machining.

La plaque-agrafe se monte par l'intermédiaire d'un positionneurimpacteur constitué d'une embase rectangulaire épousant le galbe de la plaque et la courbure des picots, au milieu de laquelle se monte une tige épaulée, à embout fileté de dimensions et de pas correspondant à ceux de l'orifice fileté situé dans le milieu de la plaque ou d' une pince. The staple plate is mounted by means of an impact positioner consisting of a rectangular base matching the curve of the plate and the curvature of the pins, in the middle of which is mounted a shouldered rod, with a threaded end of dimensions and pitch corresponding to those of the threaded hole located in the middle of the plate or a clamp.

Les avantages obtenus, grâce à cette invention, consistent essentiellement en ceci que les vertèbres ou les fragments osseux sont parfaitement stabilisés après agrafage, ce qui permet une prise massive des fragments empêchant tout mouvement dans le plan de l'ostéotomie, et que cette plaque-agrafe dont le prix de revient est très faible peut être aisément mise en place sans risque de déformation au moment de l'impactage.The advantages obtained, thanks to this invention, consist essentially in that the vertebrae or the bone fragments are perfectly stabilized after stapling, which allows a massive grip of the fragments preventing any movement in the plane of the osteotomy, and that this plate- clip whose cost price is very low can be easily installed without risk of deformation at the time of impacting.

D'autres caractéristiques et avantages apparaîtront dans la description qui va suivre d'un mode de réalisation de la plaqueagrafe selon l'invention, destinée à l'ostéosynthèse des vertèbres cervicales, donné à titre d'exemple non limitatif au regard des dessins annexés, sur lesquels - la figure 1 représente une vue de côté de la plaque-agrafe, - la figure 2 représente une vue de face de la plaque-agrafe selon la figure 1., - la figure 3 représente une vue de dessus de la plaque-agrafe selon la figure 1, - la figure 4 représente une vue développée de la plaque-agrafe selon la figurel, - la figure 5 représente une vue longitudinale en coupe du positionneur-impacteur monté sur une plaque-agrafe, - la figure 6 représente une vue en perspective de la plaqueagrafe fixée sur deux vertèbres cervicales adjacentes.Other characteristics and advantages will appear in the following description of an embodiment of the staple plate according to the invention, intended for osteosynthesis of the cervical vertebrae, given by way of nonlimiting example with regard to the appended drawings, in which - Figure 1 shows a side view of the staple plate, - Figure 2 shows a front view of the staple plate according to Figure 1., - Figure 3 shows a top view of the plate- clip according to Figure 1, - Figure 4 shows a developed view of the clip plate according to the figure, - Figure 5 shows a longitudinal sectional view of the positioner-impactor mounted on a clip plate, - Figure 6 shows a perspective view of the clip plate fixed on two adjacent cervical vertebrae.

Les figures représentent une plaque-agrafe 10 constituée d'une plaque galbée 11 munie de picots 12, de trous oblongs 13 de passage de vis de fixation 2 et d'un orifice fileté 1 4 de manutention et d'impaction par l'intermédiaire d'un positionneurimpacteur 30 constitué d'une embase 31 dans le milieu de laquelle se monte une tige épaulée 32 à embout fileté 33.The figures represent a staple plate 10 consisting of a curved plate 11 provided with pins 12, oblong holes 13 for the passage of fixing screws 2 and a threaded orifice 1 4 for handling and impaction by means of an impact positioner 30 consisting of a base 31 in the middle of which a stepped rod 32 with threaded end 33 is mounted.

En examinant plus en détail les figures l à 4, on remarque que la plaque 11 est galbée transversalement pour augmenter son moment d'inertie transversal et, par conséquent, d'augmenter sa résistance à la flexion et que les picots 1 2 sont reliés aux côtés de la plaque par une partie courbe d'assez grand rayon destinée à éliminer tout risque de réduction des caractéristiques mécaniques dans la zone de pliage comme ce serait le cas avec un pliage à angle droit.By examining Figures 1 to 4 in more detail, it will be noted that the plate 11 is curved transversely to increase its transverse moment of inertia and, consequently, to increase its resistance to bending and that the pins 1 2 are connected to the sides of the plate by a curved part of fairly large radius intended to eliminate any risk of reduction of the mechanical characteristics in the bending zone as would be the case with bending at right angles.

On remarque que les picots 1 2 comportent des dents 121 assurant un blocage cortical complémentaire de celui assuré par les vis de fixation 2 introduites dans les trous oblongs 1 3 de la plaque galbée 11. It is noted that the pins 1 2 have teeth 121 ensuring cortical blocking complementary to that provided by the fixing screws 2 introduced into the oblong holes 1 3 of the curved plate 11.

En se reportant à la figure 5, on remarque que la plaque-agrafe 10 peut être aisément mise en place sans risque de déformation, par l'intermédiaire du positionneur-impacteur 30, dont l'embase 31 épouse parfaitement la forme du galbe de la plaque 1 1 et de la courbure des picots 1 2. Ainsi, tout effort appliqué sur la tige épaulée 32 est retransmis intégralement à la plaque-agrafe qui est maintenue en appui contre l'embase par l'intermédiaire de l'embout fileté 33 vissé dans l'orifice fileté 14 de la plaque galbée 11. Après positionnement et impaction, il sera ainsi très facile de démonter le positionneur-impacteur 30 par simple rotation de la tige 32 de celui-ci dans le sens du dévissage de l'embout fileté 33. Il suffit alors de consolider l'assemblage par l'intermédiaire des vis 2 dont la têtue fraisée prend appui sur les bords des trous oblongs 13.Referring to FIG. 5, it can be seen that the staple plate 10 can be easily put in place without risk of deformation, by means of the positioner-impactor 30, the base 31 of which perfectly matches the shape of the curve of the plate 1 1 and the curvature of the pins 1 2. Thus, any force applied to the shouldered rod 32 is fully transmitted to the staple plate which is held in abutment against the base by means of the threaded end piece 33 screwed in the threaded orifice 14 of the curved plate 11. After positioning and impaction, it will thus be very easy to dismantle the positioner-impactor 30 by simple rotation of the rod 32 thereof in the direction of unscrewing the threaded end piece 33. It then suffices to consolidate the assembly by means of the screws 2, the milled head of which bears on the edges of the oblong holes 13.

En examinant maintenant la figure 6, on remarque qu'il est ainsi possible, par ces moyens, de solidariser deux vertèbres adjacentes 4 et 5.Now examining FIG. 6, it is noted that it is thus possible, by these means, to join two adjacent vertebrae 4 and 5 together.

La plaque-agrafe selon l'invention peut être obtenue par découpage pliage classique ou découpée par électrokrosion ou par rayon laser.The staple plate according to the invention can be obtained by conventional folding cutting or cutting by electrokrosion or by laser beam.

Toutefois, elle pourrait être réalisée par moulage préférentiellement, le métal utilisé est du TA6V4EU. However, it could preferably be produced by molding, the metal used is TA6V4EU.
