Abstract

Invention concernant un implant inter-vertébral composite destiné à être placé entre les apophyses épineuses et formé d'une coque métallique en deux parties pouvant s'emboîter l'une dans l'autre et d'un noyau en textile synthétique.The invention relates to a composite intervertebral implant intended to be placed between the spinous processes and formed of a metal shell in two parts which can fit into each other and of a synthetic textile core.

Description

IMPLANT INTEREPINEUX A COQUE METALLIQUE DOUBLE
Le dispositif objet du présent brevet vise à stabiliser deux ou plusieurs vertébres consécutives en les fixant entre elles deux par deux au moyen d'un implant inter-épineux à coque métallique bivalve à noyau textile synthétique.INTEREPINOUS IMPLANT WITH DOUBLE METAL HULL
The device which is the subject of this patent aims to stabilize two or more consecutive vertebrae by fixing them two by two using an interspinous implant with a bivalve metal shell with synthetic textile core.

On a proposé pour fixer les apophyses épineuses entre elles des cales interépineuses semi-rigides avec des dispositifs d'amarrage incorporés de mise en place facile. Semi-rigid interspinous wedges have been proposed for fixing the spinous processes therebetween with incorporated mooring devices for easy positioning.

Ce dispositif n'apporte pas d'amortissement. This device does not provide any depreciation.

De ce fait, on peut craindre qu'il ne génère des vibrations entrainant à la longue des fissures au niveau de l'implantation sur les apophyses épineuses. As a result, it is feared that it will generate vibrations which in the long term will cause cracks in the area of implantation on the spinous processes.

L'implant objet du présent brevet est composite. The implant which is the subject of this patent is composite.

I1 comprend un noyau en matière synthétique tressée qui a un rôle de comblement dont la taille varie en fonction de l'espace interépineux à appareiller et une coque métallique faite de deux parties, qui contiennent le noyau en matière synthétique tressée et évitent son fluage. I1 comprises a core of braided synthetic material which has a filling role whose size varies according to the interspinous space to be fitted and a metal shell made of two parts, which contain the core of braided synthetic material and prevent its creep.

Ces deux parties métalliques sont réalisées de manière à ce que la pièce caudale puisse s'emboiter dans la coque craniale et coulisser légèrement à l'intérieur de cette dernière, réalisant ainsi un amortissement lors des mouvements réciproques des vertébres. These two metal parts are made in such a way that the caudal part can fit into the cranial shell and slide slightly inside the latter, thus achieving damping during the reciprocal movements of the vertebrae.

Sur les deux pièces métalliques se fixent des appendices métalliques, deux sur la partie craniale et deux sur la partie caudale, formant des tenons destinés à recevoir et à contenir les apophyses épineuses correspondantes, formant les mortaises. On the two metal parts are attached metal appendages, two on the cranial part and two on the caudal part, forming tenons intended to receive and contain the corresponding spinous processes, forming the mortises.

L'implant est formé de trois parties
A) Le noyau textile tressé est enroulé sur lui-même de manière à s'adapter à la forme de la pièce métallique craniale dans laquelle il s'emboite. The implant is made up of three parts
A) The braided textile core is wound on itself so as to adapt to the shape of the cranial metal part in which it fits.

B) Une partie métallique supérieure en forme de demi-cylindre creux comportant à décrire
* une face supérieure en forme de demi-disque dont le coté aplati est antérieur et le coté en demi cercle est postérieur.B) An upper metal part in the form of a hollow half-cylinder comprising to describe
* an upper face in the form of a semi-disc whose flattened side is anterior and the semi-circular side is posterior.

L'union entre les deux cotés est arrondie de manière à éviter tout angle vif. Sur la partie craniale de cette face s'implantent deux tenons destinés à s'ajuster au bord inférieur de l'apophyse supérieure.The union between the two sides is rounded so as to avoid any sharp angles. On the cranial part of this face are implanted two tenons intended to adjust to the lower edge of the upper process.

* une face postérieure arrondie en demi-cylindre. * a posterior face rounded in half-cylinder.

* une face antérieure plane se raccordant sans angle vif à la partie postérieure. * a flat anterior face connecting without sharp angle to the posterior part.

* le demi-cylindre ainsi réalisé est évidé à sa partie caudale de manière à recevoir le noyau textile de remplissage. * the half-cylinder thus produced is hollowed out at its caudal part so as to receive the textile filling core.

C) Une partie métallique inférieure en forme de plateau formant un demi-disque avec un coté aplati antérieur et un coté semicirculaire postérieur se raccordant à angle mousse. Ce demidisque reçoit à sa partie craniale une tige métallique perpendiculaire qui est destinée à se fixer à l'intérieur du noyau textile dans un orifice ménagé à cet usage.C) A lower metal part in the form of a plate forming a half-disc with an anterior flattened side and a posterior semicircular side connecting at a foam angle. This semi-disc receives at its cranial part a perpendicular metal rod which is intended to be fixed inside the textile core in an orifice provided for this purpose.

De l'autre coté du demi-disque sont fixés deux appendices formant un tenon destiné à contenir le bord cranial de l'apophyse épineuse de la vertébre inférieure. On the other side of the half-disc are attached two appendages forming a tenon intended to contain the cranial edge of the spinous process of the lower vertebra.

La taille du demi-disque inférieur lui permet de coulisser à l'intérieur de la partie métallique craniale. The size of the lower half-disc allows it to slide inside the cranial metal part.

La mise en place de l'implant se fait par un abord chirurgical, par voie postérieure, de la colonne vertébrale. The implant is placed by a surgical approach, posteriorly, of the spine.

L'espace inter-épineux est débarrassé des ligaments inter-épineux et des débris périostés.The interspinous space is cleared of interspinous ligaments and periosteal debris.

* les apophyses épineuses sont préparées à l'aide de rapes, reproduisant en creux la forme des tenons supérieurs et inférieurs.* the spinous processes are prepared using rapes, reproducing in hollow the shape of the upper and lower posts.

* quand la préparation osseuse est suffisante, une famille de fantômes, reproduisant l'encombrement total pour chaque taille d'implant, est utilisée pour choisir la bonne taille de l'implant * puis l'implant choisi est ajusté entre les apophyses épineuses à frottement dur.* when the bone preparation is sufficient, a family of phantoms, reproducing the total size for each size of implant, is used to choose the correct size of the implant * then the implant chosen is adjusted between the spinous processes with friction hard.

* la fixation peut être complétée par l'utilisation d'attaches en textile synthétique, passées dans les espaces inter-épineux supérieurs et inférieurs. * the fixation can be completed by the use of synthetic textile fasteners, passed in the upper and lower interspinous spaces.
