Description

Dispositif d'articulation pour l'assemblage de plusieurs éléments, notamment pour fixateur externe destiné à l'osté- ostynthèse. Articulation device for the assembly of several elements, in particular for an external fixator intended for osteo-synthesis.

La présente invention a pour objet un dispositif d'articulation pour l'assemblage de plusieurs 6 ments notamment pour fixateur externe destiné à l'ostéosynthèse. The present invention relates to an articulation device for the assembly of several elements, in particular for an external fixator intended for osteosynthesis.

Pour la liaison de plusieurs éléments, il est connu d'utiliser des moyens de liaison qui sont souvent compliqués et ne permettent pas une orientation dans toutes les directions. For the connection of several elements, it is known to use connection means which are often complicated and do not allow orientation in all directions.

Conformément à la présente invention, on utilise un dispositif d'articulation dans lequel les éléments à assembler et les organes de liaison entre ces éléments comportent chacun au moins une face annulaire crantée qui est susceptible d'être engagée avec une face annulaire crantée correspondante d'un autre élément ou organe de liaison ladite face annulaire crantée présentant un alésage central pour le passage d'un organe de fixation d'un élément d'un organe de liaison. According to the present invention, an articulation device is used in which the elements to be assembled and the connecting members between these elements each comprise at least one notched annular face which is capable of being engaged with a corresponding notched annular face of another element or connecting member said notched annular face having a central bore for the passage of a fastening member of an element of a connecting member.

Ce dispositif présente des possibilités nombreuses de liaisons rigides et orientables sans limite de direction dans l'espace. This device presents numerous possibilities of rigid and orientable connections without limit of direction in space.

Ce procédé d'articulation peut être utilisé dans différents domaines de construction, notamment des structures métalliques et des assemblages de structures très sophistiquées qui exigent une grande rigidité. This articulation process can be used in various construction fields, in particular metallic structures and assemblies of very sophisticated structures which require great rigidity.

Suivant une autre caractéristique de l'invention, le dispositif d'articulation est utilisé dans le domaine médical de l'ostéosynthèse. According to another characteristic of the invention, the articulation device is used in the medical field of osteosynthesis.

Ce fixateur est conçu avec une articulation crantée multifaces qui présente des orientations multiples, une fiabilité de rigidité et une très grande simplicité d'emploi par rapport aux fixateurs fabriqués actuellement.
Cette conception du dispositif d'articulation permet d'éliminer toute une série de pièces mécaniques fra giles qui nécessitent pour leur réalisation des matériaux résistants qui sont lourds et difficiles a usiner ou des matériaux légers qui nécessitent une protection de surface, résistent mal aux températures de l'autoclave et aux agents chimiques.This fixator is designed with a multi-sided notched articulation which has multiple orientations, a reliability of rigidity and a very great simplicity of use compared to the fixers currently manufactured.
This design of the articulation device makes it possible to eliminate a whole series of fragile mechanical parts which require, for their production, resistant materials which are heavy and difficult to machine, or light materials which require surface protection, do not withstand temperatures well. autoclave and chemical agents.

Ce dispositif d'articulation permet de concevoir une fabrication d'éléments du fixateur en matière plastique suivant deux versions. This articulation device makes it possible to design a production of elements of the plastic fixer in two versions.

Premièrement pour plusieurs usages on peut réaliser un appareil constitué d'un matériau composite résistant à la stérilisation médicale et à l'usure mécanique. First, for several uses, an apparatus made of a composite material resistant to medical sterilization and mechanical wear can be produced.

Secondement, on peut réaliser un appareil qui ne sert qu'une seule fois et qui peut être jeté après son utilisation. Secondly, one can make a device which is used only once and which can be discarded after its use.

Dans ce dernier cas, il sera présenté sous emballage stérilisé et prêt à l'emploi. In the latter case, it will be presented in sterilized packaging and ready for use.

Pour la chirurgie ce procédé présente les avantages suivants:
- Plus de récupération de pièces,
- Plus de stérilisation après chaque emploi,
- Plus de réparations de pièces défectueuses ayant déjà été utilisées.For surgery, this process has the following advantages:
- No more parts recovery,
- No more sterilization after each use,
- No more repairs to defective parts that have already been used.

Pour le malade ce procédé a pour avantage de permettre de réaliser des appareils ultra-légers donc plus faciles à supporter. For the patient, this process has the advantage of making it possible to produce ultra-light devices which are therefore easier to bear.

D'autres caractéristiques et avantages de l'invention seront mieux compris à la lecture de la description qui va suivre de plusieurs modes de réalisation et en se référant aux dessins annexés, sur lesquels:
- la figure 1 est une vue éclatée d'un dispositif d'articulation suivant l'invention.Other characteristics and advantages of the invention will be better understood on reading the following description of several embodiments and with reference to the appended drawings, in which:
- Figure 1 is an exploded view of a hinge device according to the invention.

- la figure 2 est une vue en élévation d'un fixateur externe destiné à l'ostéosynthèse. - Figure 2 is an elevational view of an external fixator for osteosynthesis.

- la figure 3 est une vue en plan du dispositif fixateur représenté à la figure 2.  - Figure 3 is a plan view of the fixing device shown in Figure 2.

A la figure 1 on a représenté un dispositif d'articulation suivant l'invention qui comprend un élément 1 destine a être assemble r# un autre élément 3 par l'inter mrdiaire d'un organe de liaison 2 en forme d'équerre.  In Figure 1 there is shown a hinge device according to the invention which comprises an element 1 intended to be assembled r # another element 3 by means of a connecting member 2 in the form of a square.

L'élément 1 comporte une face annulaire crantée 4 qui est engagée avec une face annulaire crantée correspondante 5 de longane de liaison 2. Dans la partie centrale de la face annulaire 4, il est prévu un alésage 6 dans lequel est engagée une vis 7 dont la partie filetée 7a, est vissée dans un trou taraudé 8 disposé au centre de la face annulaire 5, pour fixer l'organe de liaison 2, sur l'élément 1. The element 1 comprises a notched annular face 4 which is engaged with a corresponding notched annular face 5 of connecting longan 2. In the central part of the annular face 4, there is provided a bore 6 in which is engaged a screw 7 of which the threaded part 7a is screwed into a threaded hole 8 disposed in the center of the annular face 5, to fix the connecting member 2, on the element 1.

Sur l'autre face perpendiculaire a la face annulaire 5 l'organe de liaison 2 comporte une autre face annulaire 5a, identique qui est engagée avec une face annulaire crantée 9de l'élément 3. La fixation est réalisée comme précédemment par une vis 10 qui est engagée dans un alésage 8a de l'organe de liaison 2 et vissée dans un trou taraudé prévu dans lapartie centrale de la face annulaire crantée 9 de I 'élément 3. On the other face perpendicular to the annular face 5 the connecting member 2 comprises another identical annular face 5a which is engaged with a notched annular face 9 of the element 3. The fixing is carried out as previously by a screw 10 which is engaged in a bore 8a of the connecting member 2 and screwed into a threaded hole provided in the central part of the notched annular face 9 of the element 3.

Cette disposition permet d'orienter tout d'abord l'él#ment 1 dans n'importe quelle position angulaire autour de l'axe XX1 par rapport a l'organe de liaison 2 et i 'élé:nent 3 dans nl SLmporte quelle position angulaire autour de l'axe YYl, par rapport à l'organe de liaison 2. This arrangement makes it possible first of all to orient the element # 1 in any angular position around the axis XX1 with respect to the connecting member 2 and the element: in 3 nl SLmport which position angular around the axis YYl, relative to the connecting member 2.

De même, 1l'élément 3 comporte une autre face annulaire crantée 9ag perpendiculaire d la face annulaire crante 9 et contre laquelle est engagée une face annulaire crantée 11, d'un organe de liaison 12 qui est assemblé avec
L'élément 12 au moyen d'une vis 13 engagée dans un trou ta raude 14 disposé au centre de la face annulaire crantée 9a.Likewise, the element 3 comprises another notched annular face 9ag perpendicular to the notched annular face 9 and against which is engaged a notched annular face 11, of a connecting member 12 which is assembled with
The element 12 by means of a screw 13 engaged in a stiff hole 14 disposed in the center of the notched annular face 9a.

L'organe de liaison 12 présente un alésage 15 et une fente 16 pour le montage et la fixation d'une barre ronde non représentée au dessin. The connecting member 12 has a bore 15 and a slot 16 for mounting and fixing a round bar not shown in the drawing.

Aux figures 2 et 3 on a représenté un fixateur externe destine a l'ostéosynthèse qui comprend une barre creuse 17 dans laquelle est montée coulissante une barre 18 de façon a constituer un ensemble télescopique dont le réglage est obtenu par une vis 19 et un écrou 20 montés à l'une des extrémités de la barre 17,
L'extrémité libre de la barre 18 présente comme dans l'exemple précédent des faces annulaires crantées 9, 9a, dont l'une 9a, est engagée avec une face annulaire crantée Sa d'un organe de liaison en équerre 2, qui présente une autre face annulaire perpendiculaire 5 qui est engagée avec une face annulaire 4 d'un élément 21 d'une pince.Figures 2 and 3 there is shown an external fixator for osteosynthesis which comprises a hollow bar 17 in which is slidably mounted a bar 18 so as to constitute a telescopic assembly whose adjustment is obtained by a screw 19 and a nut 20 mounted at one end of the bar 17,
The free end of the bar 18 has, as in the previous example, notched annular faces 9, 9a, one of which 9a, is engaged with a notched annular face Sa of a connecting member at angle 2, which has a another perpendicular annular face 5 which is engaged with an annular face 4 of an element 21 of a clamp.

La pince comprend un autre blément 21a, qui est fixé sur l'é- lément 21, au moyen de vis 22, 22a, l'une des vis 22 servant également à la fixation de la pince sur l'organe de liaison 2.The clamp comprises another clamp 21a, which is fixed to the element 21, by means of screws 22, 22a, one of the screws 22 also serving to fix the clamp to the connecting member 2.

Les éléments 21, 21a présentent des garnitures en matériau plastique 23, 23a, comportant des logements 24 dans l'un desquels est montée une broche 25 qui est susceptible d'être engagé avec une partie d'un os. The elements 21, 21a have fittings made of plastic material 23, 23a, comprising housings 24 in one of which is mounted a pin 25 which is capable of being engaged with part of a bone.

Cette articulation permet d'orienter au moyen de l'organe de liaison 2 la broche 25 dans toutes les directions. This articulation makes it possible to orient by means of the connecting member 2 the pin 25 in all directions.

Sur la tige 17 est monté coulissant un élément 26 en forme d'étrier qui est maintenu serré sur ladite tige au moyen d'une vis 27. On the rod 17 is slidably mounted a member 26 in the shape of a stirrup which is held tight on the said rod by means of a screw 27.

A sa partie supérieure l'étrier 26 comporte une face annulaire crantée 28 identique a celles décrites ci-dessus et qui est engagée avec une face annulaire crantée correspondante 29 d'un élément de pince 30 analogue à l'élément 21. At its upper part, the stirrup 26 has a notched annular face 28 identical to those described above and which is engaged with a corresponding notched annular face 29 of a clamp element 30 similar to the element 21.

La pince qui est constituée des éléments 30, 30a, avec leurs garnitures 31, 31a, assurent le serrage d'une deuxième broche 32 qui est maintenue serrée entre lesdites garnitures par des vis 33, 33a. The clamp which consists of the elements 30, 30a, with their linings 31, 31a, ensure the tightening of a second pin 32 which is held tight between said linings by screws 33, 33a.

Dans ce cas également, on peut régler la position angulaire de la broche 32 qui est susceptible d'être engagée avec une partie d'un os.  In this case also, one can adjust the angular position of the pin 32 which is capable of being engaged with part of a bone.

Toutes les combinaisons peuvent être envisagées en ajoutant a l'étrier 26 un organe de liaison d'équerre 2 ou tout autre organe de liaison de forme dif férente comportant des faces annulaires crantées 4, 5, Sa, 9. All combinations can be envisaged by adding to the stirrup 26 a square connecting member 2 or any other connecting member of different shape having notched annular faces 4, 5, Sa, 9.

Bien entendu, l'invention n'est pas limitative et l'homme de l'art pourra y apporter des modifications sans sortir du domaine de l'invention.  Of course, the invention is not limiting and those skilled in the art may make modifications to it without departing from the scope of the invention.
