Description

MODULE PROTHETIQUE DE CROISSANCE, EXTENSIBLE. PROSTHETIC GROWTH MODULE, EXTENSIBLE.

La présente invention concerne un module prothetique de croissance, extensible, et destiné principalement au traitement des tumeurs osseuses primitives chez les enfants. The present invention relates to an expandable prosthetic growth module intended mainly for the treatment of primary bone tumors in children.

Les modules de croissance connus fonctionnent tous sur le principe du ridoir, c'est-à-dire qu'ils comportent une vis sans fin tournant dans deux butées situées chacune à une extrémité du module. The known growth modules all operate on the turnbuckle principle, that is to say that they comprise an endless screw rotating in two stops each located at one end of the module.

Ces modules présentent deux inconvénients. These modules have two drawbacks.

En effet, sous l'action de contraintes de rotation, ces modules se de' verrouillent constamment et la vis sans fin n'est alors plus bloquée en rotation. Indeed, under the action of rotation constraints, these modules are locked constantly and the worm is then no longer blocked in rotation.

De plus, ces modules ne sont pas adaptables à des queues de reconstruction anatomique à ancrage diaphysaire conique autobloquant, et, en fin de croissance, la mise en place d'une prothèse définitive oblige à changer le module, mais également la queue de reconstruction alors que son scellement diaphysaire est généralement bon.  In addition, these modules are not adaptable to tails of anatomical reconstruction with self-locking conical diaphyseal anchoring, and, at the end of growth, the installation of a final prosthesis requires changing the module, but also the tail of reconstruction then that its diaphyseal sealing is generally good.

La présente invention a pour but d'éliminer ces inconvénients. The object of the present invention is to eliminate these drawbacks.

Le module selon l'invention permet un blocage efficace, indépendant des contraintes de rotation, de sa pièce mobile par rapport à sa pièce fixe, un blocage efficace entre ce module et une queue de reconstruction à ancrage diaphysaire, et aussi une désolidarisation aisée de ce module avec la queue de reconstruction à ancrage diaphysaire. The module according to the invention allows an effective blocking, independent of the rotation constraints, of its moving part with respect to its fixed part, an effective blocking between this module and a reconstruction tail with diaphyseal anchoring, and also an easy detachment of this module with reconstruction tail with diaphyseal anchoring.

La présente invention a pour objet un module prothétique de croissance, extensible, comportant un corps relié de manière articulée ou non à un autre module fixé dans un os en regard, et une pièce mobile reliée à â une queue de reconstruction à ancrage diaphysaire. The present invention relates to a prosthetic growth module, extensible, comprising a body connected in an articulated manner or not to another module fixed in a facing bone, and a movable part connected to a reconstruction tail with diaphyseal anchoring.

Selon l'invention, ce module comporte une bague tournante, introduite dans un évidement du corps et munie d'un orifice central fileté et traversé par la pièce mobile, le corps comportant au moins une vis empêchant la rotation de la pièce mobile, la rotation de la bague entraînant alors le déplacement longitudinal de la pièce mobile, ce qui rend ce module extensible. According to the invention, this module comprises a rotating ring, inserted into a recess in the body and provided with a threaded central orifice and traversed by the moving part, the body comprising at least one screw preventing rotation of the moving part, rotation of the ring then causing the longitudinal displacement of the movable part, which makes this module extensible.

Selon une autre caractéristique de 1 invention, la ou les vis qui empêchent la rotation de la pièce mobile, assurent également un blocage longitudinal efficace de la pièce mobile, après réglage de la longueur du module. According to another characteristic of 1 invention, the screw or screws which prevent the rotation of the moving part, also ensure effective longitudinal locking of the moving part, after adjusting the length of the module.

Selon une autre caractéristique de 1 invention, la pièce mobile comporte une embase munie d'un orifice borgne comportant un cône morse femelle et un crantage permettant la réception d'une queue de reconstruction à ancrage diaphysaire munie d'un cône morse mâle et d'un crantage complémentaire, ce qui rend ais la désolidarisation entre le module et la queue de reconstruction à ancrage diaphysaire.  According to another characteristic of 1 invention, the movable part comprises a base provided with a blind orifice comprising a female Morse cone and a notch allowing the reception of a reconstruction tail with diaphyseal anchoring provided with a male Morse cone and a complementary notching, which makes ais the separation between the module and the tail of reconstruction with diaphyseal anchoring.

Selon une autre caractéristique de 1 invention, l'embase comporte une vis dont une extrémité est engagée dans une rainure de la queue de reconstruction à ancrage diaphysaire, cette vis assurant une bonne immobilisation de la queue sur le module prothétique. According to another characteristic of 1 invention, the base comprises a screw, one end of which is engaged in a groove of the reconstruction tail with diaphyseal anchoring, this screw ensuring good immobilization of the tail on the prosthetic module.

Il est décrit ci-après, à titre d'exemple et en référence aux dessins annexés, un module prothétique selon l'invention. A prosthetic module according to the invention is described below, by way of example and with reference to the accompanying drawings.

La figure 1 montre le module et une partie d'une queue de reconstruction à ancrage diaphysaire;
la figure 2 est une coupe selon Il de la figure 1.Figure 1 shows the module and part of a reconstruction tail with diaphyseal anchoring;
FIG. 2 is a section along II of FIG. 1.

Dans la figure , le module 10 comporte un corps 11, une pièce mobile 12 et une bague filetée 13. In the figure, the module 10 comprises a body 11, a moving part 12 and a threaded ring 13.

Le corps 10 comporte, sur pratiquement toute sa longueur, un orifice central 14 à paroi lisse, un évidement 15 permettant l'introduction de la bague 13 et enfin deux orifices filetés 16 et 17 permettant l'introduction de deux vis de guidage et de blocage 24,25. Ce corps comporte également un orifice 27 assurant sa fixation à un autre module fixé dans l'os en regard qui peut être, par exemple, le tibia. The body 10 comprises, over practically its entire length, a central orifice 14 with a smooth wall, a recess 15 allowing the introduction of the ring 13 and finally two threaded orifices 16 and 17 allowing the introduction of two guide and blocking screws 24.25. This body also includes an orifice 27 ensuring its attachment to another module fixed in the opposite bone which may be, for example, the tibia.

La pièce mobile 12 est constituée principalement d'une partie filetée 18 qui pénètre dans l'orifice 14 du corps 11, et une embase 19 qui reçoit l'extrémité d'une queue de reconstraction 1 logée dans le fémur, par exemple. The movable part 12 mainly consists of a threaded part 18 which penetrates into the orifice 14 of the body 11, and a base 19 which receives the end of a reconstruction tail 1 housed in the femur, for example.

La partie 18 de la pièce mobile 12 du module comporte, sur toute la longueur filetée, une encoche 29 mieux visible en figure 2, dans laquelle viennent s engager les vis 24 et 25. The part 18 of the movable part 12 of the module comprises, over the entire threaded length, a notch 29 better visible in FIG. 2, in which the screws 24 and 25 engage.

L'embase 19 comporte, en regard de la partie filetée, un orifice comportant un cône morse femelle 20 et une partie cylindrique munie d'un crantage 21. Ce cône morse 20 reçoit un cône mâle complémentaire 2 de la queue 1 et le crantage 21 reçoit un crantage complémentaire 4 de la queue 1. Entre le cône morse mâle 2 et le crantage mâle 4, la queue est munie d'une rainure 3 et, entre le cône morse femelle 20 et le crantage femelle 21, l'embase 19 est munie d'un orifice fileté 22 recevant une vis 23 dont l'extrémité s'engage dans la rainure 3 de la queue 1, afin de solidariser en translation la queue 1 et la pièce mobile 12 du module. The base 19 comprises, opposite the threaded part, an orifice comprising a female Morse cone 20 and a cylindrical part provided with a notch 21. This Morse cone 20 receives a complementary male cone 2 of the tail 1 and the notch 21 receives a complementary notch 4 of the tail 1. Between the male walrus cone 2 and the male notch 4, the tail is provided with a groove 3 and, between the female morse cone 20 and the female notch 21, the base 19 is provided with a threaded orifice 22 receiving a screw 23 whose end engages in the groove 3 of the tail 1, in order to secure in translation the tail 1 and the moving part 12 of the module.

La bague filetée 13, engagée dans l'évidement 15 du corps 11, comporte huit orifices 26 répartis sur sa circonférence et permettant sa rotation au moyen d'un outil spécial engagé dans un orifice 26. The threaded ring 13, engaged in the recess 15 of the body 11, has eight holes 26 distributed around its circumference and allowing its rotation by means of a special tool engaged in a hole 26.

La queue de reconstruction 1 est une queue à ancrage sans ciment, fabriquée en titane pour augmenter sa résistance et avoir une élasticité plus proche de celle de l'os. Seule l'extrémité de cette queue est représentée, mais bien entendu, cette queue a une forme conique adaptée au canal médullaire de l'os, de façon à favociser l'augmentation de la surface de contact ainsi que l'ancrage osseux. Cet ancrage se fera directement sur la queue après recouvrement de celle-ci d'une substance ostéo-inductrice.  The reconstruction tail 1 is a cementless anchor tail, made of titanium to increase its resistance and have an elasticity closer to that of the bone. Only the end of this tail is shown, but of course, this tail has a conical shape adapted to the medullary canal of the bone, so as to promote the increase in the contact surface as well as the bone anchoring. This anchoring will be done directly on the tail after covering it with an osteoinductive substance.

La queue 1 comporte en outre un orifice 5 qui permet le verrouillage de cette queue sur l'os. The tail 1 further comprises an orifice 5 which allows the locking of this tail on the bone.

Un tel module est mis en place de la manière suivante
après avoir engage la queue à ancrage diaphysaire dans l'os, le module est mis en place suc l'extcémité de la queue, et la vis 23 est bloquée, assurant ainsi l'immobilisation longitudinale entre la queue et le module. Le corps du module est ensuite connecté, au moyen de l'orifice 27, au module en vis-à-vis. Such a module is implemented in the following manner
after engaging the tail with diaphyseal anchoring in the bone, the module is put in place at the end of the tail, and the screw 23 is blocked, thus ensuring the longitudinal immobilization between the tail and the module. The body of the module is then connected, by means of the orifice 27, to the facing module.

Quand l'enfant grandit, il est nécessaire de temps à autre, de rallonger le module et l'opération s'effectue alors de la manière suivante
après déblocage des vis 24 et 25, le chirurgien fait tourner, àa'l'aide d'un outil spécial engagé successivement dans les orifices 26, la bague 13 dans le sens approprié à l'allongement de ce module.When the child grows up, it is necessary from time to time to lengthen the module and the operation is then carried out as follows
after the screws 24 and 25 are released, the surgeon rotates, using a special tool successively engaged in the orifices 26, the ring 13 in the direction appropriate for the elongation of this module.

arrivé à l'allongement désiré, on bloque les deux vis 24 et 25.arrived at the desired elongation, we lock the two screws 24 and 25.

En cas de nécessités techniques, on peut facilement enlever le module prot'nétique pour le remplacer par un autre module, ou en fin de croissance, on peut remplacer le module par un module adulte, sans retirer la queue de reconstruction 1. Pour ce faire, il suffit de débloquer la vis 23 et de désolidariser 1'embase 19 de la queue 1.  In case of technical needs, the prot'netic module can be easily removed to replace it with another module, or at the end of growth, the module can be replaced by an adult module, without removing the reconstruction tail 1. To do this , it suffices to unlock the screw 23 and separate the base 19 from the tail 1.
