Description

ENSEMBLE POUR PREPARATION D'ARTHRODESE INTERVERTEBRALE
La présente invention a pour objet un ensemble pour discectom ie. ASSEMBLY FOR PREPARATION OF INTERVERTEBRAL ARTHRODESIS
The present invention relates to an assembly for discectom ie.

Les différentes techniques d'arthrodèse sont connues depuis longtemps. La plus simple de ces méthodes est la méthode dite intraarticulaire, selon laquelle on joint les surfaces de l'os ensemble après avoir éliminé le cartilage articulaire. Si nécessaire, on bloque les articulations par des plaques servant de pont extérieur à travers l'articulation (méthode extraarticulaire). The various arthrodesis techniques have been known for a long time. The simplest of these methods is the so-called intraarticular method, in which the surfaces of the bone are joined together after removing the articular cartilage. If necessary, the joints are blocked by plates serving as an external bridge through the joint (extraarticular method).

Dans le cas des lésions de la colonne vertébrale, on réalise un ancrage osseux temporaire des vertèbres blessées de manière similaire, par voie opératoire. In the case of lesions of the spine, temporary bone anchoring of the injured vertebrae is carried out in a similar manner, by the operative route.

L'ancrage peut être réalisé par plusieurs méthodes. II est connu d'utiliser des plaques simples, des plaques pourvues de fixations dynamiques à ressort, des dispositifs mécaniques comprenant des vis et des tiges ou bien d'autres fixateurs externes. Anchoring can be achieved by several methods. It is known to use simple plates, plates provided with dynamic spring fasteners, mechanical devices comprising screws and rods or other external fasteners.

II faut préparer un alésage entre les deux vertèbres, à l'emplacement du disque. Pour que ces deux vertèbres fusionnent, il faut dans cet alésage placer des cages remplies d'os ou l'os seul. It is necessary to prepare a bore between the two vertebrae, at the location of the disc. So that these two vertebrae merge, it is necessary in this bore to place cages filled with bone or the bone alone.

Les cages permettent de maintenir l'écart entre les vertèbres pour que la greffe puisse prendre. The cages help maintain the gap between the vertebrae so that the graft can take.

Au cours de l'opération, beaucoup de difficultés résident dans le fait que les alésages pour les cages doivent être réalisés dans un endroit approprié, d'une manière appropriée et en grande sécurité. Notamment, la qualité de la fixation peut être améliorée de manière importante si les alésages peuvent être réalisés dans les tissus osseux appropriés, de façon reproductible et, en même temps, la lésion des nerfs, des veines, etc..., qui sont à proximité, doit être évitée. During the operation, many difficulties reside in the fact that the bores for the cages must be carried out in an appropriate place, in an appropriate manner and in great safety. In particular, the quality of the fixation can be improved significantly if the bores can be made in the appropriate bone tissue, in a reproducible manner and, at the same time, the lesion of the nerves, veins, etc. which are proximity, should be avoided.

La présente invention vise donc un ensemble pour discectomie permettant l'élimination des désavantages. The present invention therefore relates to a discectomy assembly allowing the elimination of disadvantages.

La présente invention vise donc un ensemble pour discectomie permettant l'élimination des désavantages mentionnés ci-dessus et la réalisation des alésages de façon reproductible et en grande sécurité au cours de la préparation de l'arthrodèse.  The present invention therefore relates to an assembly for discectomy allowing the elimination of the disadvantages mentioned above and the production of the bores in a reproducible manner and in great safety during the preparation of the arthrodesis.

Ce but est atteint à l'aide de l'ensemble selon l'invention comprenant un tube guide, des forets et des tarauds. This object is achieved using the assembly according to the invention comprising a guide tube, drills and taps.

L'extrémité du tube guide est biseautée et pénètre dans la matière osseuse. The end of the guide tube is bevelled and enters the bone material.

On fixe ainsi ledit tube dans la position adéquate pendant la durée de l'intervention. Said tube is thus fixed in the appropriate position for the duration of the intervention.

Le tube guide est pourvue d'une tête à paroi épaissie dans laquelle une poignée perpendiculaire sur l'axe du tube est fixée. The guide tube is provided with a thickened wall head in which a handle perpendicular to the axis of the tube is fixed.

Les tiges des forets et des tarauds, de différentes dimensions, s'ajustent aux alésages des tubes. The rods of the drills and taps, of different dimensions, adjust to the bores of the tubes.

Les tarauds ont des diamètres supérieurs à ceux des forêts. The taps have diameters larger than those of forests.

L'ensemble selon l'invention permet la réalisation d'alésages entre les deux vertèbres, dans le disque, à l'endroit et sous l'angle bien défini par le tube guide qui protège la dure-mère et ses racines, en grande sécurité et en qualité reproductible. The assembly according to the invention allows the production of bores between the two vertebrae, in the disc, at the location and at the angle well defined by the guide tube which protects the dura mater and its roots, in great safety. and in reproducible quality.

L'invention a principalement pour objet un ensemble d'instruments chirurgicaux pour la préparation d'arthrodèse intervertébrale, caractérisé par le fait qu'il comporte des forets aux tiges allongées de différentes dimensions ainsi que des tubes guides dans les alésages desquels les tiges des forets et des tarauds s'ajustent. The invention mainly relates to a set of surgical instruments for the preparation of intervertebral arthrodesis, characterized in that it comprises drills with elongated stems of different dimensions as well as guide tubes in the bores of which the stems of the drills and taps adjust.

L'invention a également pour objet un ensemble, caractérisé par le fait que le tube guide est pourvu d'une tête à paroi épaissie et qu'une poignée perpendiculaire sur l'axe du tube est fixée dans la tête. The invention also relates to an assembly, characterized in that the guide tube is provided with a thickened wall head and that a perpendicular handle on the axis of the tube is fixed in the head.

L'invention a également pour objet un ensemble, caractérisé par le fait qu'il contient également des filières de différentes dimensions, pourvues de tiges allongées qui s'ajustent dans l'alésage du tube guide. The invention also relates to an assembly, characterized in that it also contains dies of different dimensions, provided with elongated rods which adjust in the bore of the guide tube.

L'invention a également pour objet un ensemble, caractérisé par le fait que sur les tiges des forets et/ou des tarauds, on a prévu des butées. The invention also relates to an assembly, characterized in that on the rods of the drills and / or taps, there are provided stops.

L'invention a également pour objet un ensemble, caractérisé par le fait que les tiges des forets et des tarauds sont pourvues de supports. The invention also relates to an assembly, characterized in that the rods of the drills and taps are provided with supports.

L'invention a également pour objet un ensemble, caractérisé par le fait que les tiges des tarauds sont pourvues de poignées. The invention also relates to an assembly, characterized in that the rods of the taps are provided with handles.

L'invention pourra être encore mieux comprise à l'aide de i'exemple qui suit et du dessin annexé.  The invention can be understood even better with the aid of the example which follows and the attached drawing.

Sur le dessin:
- la figure 1 montre le tube guide selon l'invention,
- la figure 2 montre le foret faisant partie de l'ensemble selon l'invention,
- la figure 3 montre le taraud faisant partie de l'ensemble selon l'invention.On the drawing:
FIG. 1 shows the guide tube according to the invention,
FIG. 2 shows the drill forming part of the assembly according to the invention,
- Figure 3 shows the tap forming part of the assembly according to the invention.

Dans le mode d'exécution présenté sur la figure 1, L'alésage 2 du tube guide 1 possède le même diamètre tout le long du tube. Sur la face extérieure, en haut du tube, on a prévu une tête 3, une poignée 4 étant fixée sur cette tête. In the embodiment presented in FIG. 1, the bore 2 of the guide tube 1 has the same diameter all along the tube. On the outside, at the top of the tube, a head 3 is provided, a handle 4 being fixed on this head.

La figure 2 montre le foret 5 comprenant une mèche 6 et une longue tige 7, solidarisée avec une tête support 8 pouvant être munie d'une poignée (non représentée). Figure 2 shows the drill 5 comprising a drill bit 6 and a long rod 7, secured to a support head 8 which can be provided with a handle (not shown).

La figure 3 montre un taraud ou une filière 9 pourvu d'un peigne 10 et d'une poignée 12 relié par l'intermédiaire d'une longue tige 11. FIG. 3 shows a tap or a die 9 provided with a comb 10 and a handle 12 connected by means of a long rod 11.

La tige du foret 5 ainsi que celle du taraud 9 ont le même diamètre, ces tiges s'ajustent d'une manière précise à l'alésage 2 du tube guide 1. Entre la tige 7 et la tête 8 du foret 5 ainsi qu'entre la tige 11 et la poignée 12 de la filière 9, on a prévu un épaulement formant une butée 13 ayant un diamètre supérieur à celui de l'alésage 2. The rod of the drill 5 as well as that of the tap 9 have the same diameter, these rods adjust in a precise manner to the bore 2 of the guide tube 1. Between the rod 7 and the head 8 of the drill 5 as well as between the rod 11 and the handle 12 of the die 9, a shoulder is provided forming a stop 13 having a diameter greater than that of the bore 2.

Au cours de l'opération, en dirigeant le tube guide 1 d'une manière précise, on peut l'ajuster à l'endroit où l'on veut réaliser l'alésage. On fait le forage à l'aide du foret 5 en maintenant le tube guide 1 pendant cette opération à l'endroit désiré. La profondeur de l'alésage peut être définie de façon précise étant donné que la butée 13 se trouve retenue par le tube guide 1, donc les alésages préparés par le même tube guide et le même foret auront obligatoirement les mêmes dimensions. During the operation, by directing the guide tube 1 in a precise manner, it can be adjusted to the place where one wishes to make the bore. Drilling is carried out using the drill 5 while maintaining the guide tube 1 during this operation at the desired location. The depth of the bore can be precisely defined since the stop 13 is retained by the guide tube 1, so the bores prepared by the same guide tube and the same drill will necessarily have the same dimensions.

De façon similaire, le taraud 9 entre également dans le tube guide 1, ce qui permet de réaliser le filetage avec grande sécurité et d'une manière précise également, sans que l'outil ne puisse basculer ou se coincer. Similarly, the tap 9 also enters the guide tube 1, which allows the threading to be carried out with great safety and also in a precise manner, without the tool being able to tilt or get caught.

On peut éviter avec une grande sécurité d'endommager des arêtes de coupe et de tissu osseux par le fait qu'au moment d'arriver au fond de l'alésage, la butée 13 au bout de la tige 1 1 du taraud 9 se trouve retenue par le tube guide 1 et on ne peut pas continuer le filetage. Damage to cutting edges and bone tissue can be avoided with great security by the fact that when reaching the bottom of the bore, the stop 13 at the end of the rod 1 1 of the tap 9 is located retained by the guide tube 1 and the thread cannot be continued.

Bien entendu, I'exemple présenté ne sert que pour l'illustration de l'invention et n'a aucun effet limitatif à l'étendue des revendications qui suivent. II est évident que, restant toujours dans le cadre de l'invention,
L'ensemble peut être réalisé avec beaucoup de variantes. Of course, the example presented only serves to illustrate the invention and has no limiting effect on the scope of the claims which follow. It is obvious that, still remaining within the scope of the invention,
The set can be made with many variations.
