Description

"OBTURATEUR POUR CAVITES OSSEUSES"
La présente invention concerne un obturateur pour cavités osseuses réalisé en au moins un matériau biocompatible résorbable."SHUTTER FOR BONE CAVITES"
The present invention relates to a obturator for bone cavities made of at least one absorbable biocompatible material.

L'invention trouve une application particulièrement avantageuse à la pose, avec ciment chirurgical, de prothèses ou d'implants en chirurgie orthopédique. The invention finds a particularly advantageous application in the fitting, with surgical cement, of prostheses or implants in orthopedic surgery.

Lors d'une pose d'une prothèse ou implant destiné à être fixé par du ciment chirurgical à l'intérieur d'une cavité osseuse, tel que le canal médullaire d'un os, un obturateur est généralement placé à un endroit précis de ladite cavité pour: - éviter que le ciment ne pénètre plus profondément que nécessaire dans le canal médullaire, - rendre plus homogène la répartition du ciment autour de la prothèse ou implant, et obtenir ainsi, une fixation meilleure et plus durable. When placing a prosthesis or implant intended to be fixed by surgical cement inside a bone cavity, such as the medullary canal of a bone, a obturator is generally placed at a precise location of said cavity to: - prevent the cement from penetrating deeper than necessary into the medullary canal, - make the distribution of cement around the prosthesis or implant more homogeneous, and thus obtain a better and more durable fixation.

Actuellement, la mise en place de tels obturateurs en matériau biocompatible résorbable exige: - un nombre important d'obturateurs de différents diamètres, - l'utilisation préalable de gabarits, - au moins trois temps opératoires, - une attention supplémentaire et contraignante dans une phase opératoire critique, ce qui pour certains chirurgiens n'est pas en rapport avec le gain escompté. Currently, the installation of such shutters in absorbable biocompatible material requires: - a large number of shutters of different diameters, - the prior use of templates, - at least three operating times, - additional and restrictive attention during a phase critical operating, which for some surgeons is not related to the expected gain.

Aussi, la présente invention a pour but de proposer
un obturateur pour cavités osseuses, réalisé en au moins un matériau biocompatible résorbable, qui permettrait de simplifier notablement les opérations de positionnement dans lesdites cavités, tout en garantissant des qualités d'obturation bien supérieures à celles actuellement obtenues.Also, the present invention aims to provide
a obturator for bone cavities, made of at least one absorbable biocompatible material, which would make it possible to considerably simplify the positioning operations in said cavities, while guaranteeing sealing qualities much superior to those currently obtained.

Ce but est atteint, conformément à l'invention, du fait que ledit obturateur comporte un élément en matériau souple apte à s'expanser latéralement de manière à produire une obturation forcée desdites cavités osseuses. This object is achieved, according to the invention, because said obturator comprises an element made of flexible material capable of expanding laterally so as to produce a forced obturation of said bone cavities.

I1 est également proposé divers modes de réalisation d'obturation forcée par expansion latérale de l'élément en matériau souple de l'obturateur de l'invention. I1 is also proposed various embodiments of forced shutter by lateral expansion of the element of flexible material of the shutter of the invention.

Selon un premier mode de réalisation par déformation sous compression, ledit élément en matériau souple est un composant de forme sensiblement cylindrique, traversé par un axe en matériau rigide, muni d'une pluralité de crans de retenue et portant à une première extrémité une butée fixe pour ledit composant, ledit composant souple étant surmonté, à une deuxième extrémité dudit axe rigide, par une rondelle de verrouillage, également en matériau rigide, destiné à coopérer avec lesdits crans de retenue lorsque le composant souple est soumis à un effort de compression appliqué sur ladite rondelle de verrouillage. According to a first embodiment by compression deformation, said element made of flexible material is a component of substantially cylindrical shape, crossed by an axis of rigid material, provided with a plurality of retaining notches and carrying at a first end a fixed stop for said component, said flexible component being surmounted, at a second end of said rigid axis, by a locking washer, also made of rigid material, intended to cooperate with said retaining notches when the flexible component is subjected to a compressive force applied to said locking washer.

Selon un deuxième mode de réalisation par remplissage, ledit élément en matériau souple est une enveloppe fermée par une vanne rigide d'introduction à l'intérieur de ladite enveloppe d'un matériau fluide sous pression. According to a second embodiment by filling, said element made of flexible material is an envelope closed by a rigid valve for introducing inside said envelope of a fluid material under pressure.

Enfin, selon un troisième mode de réalisation par recouvrement élastique, ledit élément en matériau souple est un bouchon réalisé en un matériau de reprise de forme après compression latérale dudit bouchon. Finally, according to a third embodiment by elastic covering, said element made of flexible material is a stopper made of a material for resuming shape after lateral compression of said stopper.

De même, un procédé de mise en place de l'obturateur, objet de l'invention, à l'intérieur d'une cavité osseuse est remarquable en ce que, ledit procédé consiste, à l'aide d'un ancillaire, à amener ledit obturateur à la position choisie par le praticien, puis à mettre l'obturateur en expansion latérale dans ladite cavité osseuse. Likewise, a method of placing the obturator, object of the invention, inside a bone cavity is remarkable in that, said method consists, using an ancillary device, in bringing said obturator in the position chosen by the practitioner, then putting the obturator in lateral expansion in said bone cavity.

L'obturateur conforme à l'invention présente un grand nombre d'avantages par rapport aux obturateurs connus. The shutter according to the invention has a large number of advantages compared to known shutters.

L'expansion de l'obturateur est obtenue une fois que celui-ci est positionné dans la cavité osseuse, à l'emplacement déterminé par le praticien. L'obturateur mis en expansion latérale occupe alors la totalité de ladite cavité avec adéquation parfaite aux formes irrégulières de la section osseuse à l'endroit retenu par le chirurgien. The expansion of the obturator is obtained once it is positioned in the bone cavity, at the location determined by the practitioner. The obturator set in lateral expansion then occupies the whole of said cavity with perfect adequacy to the irregular shapes of the bone section at the location retained by the surgeon.

L'obturateur de l'invention évite l'utilisation de gabarits ou encore d'un ancillaire à force pour enfoncer et mettre en place ledit obturateur. The shutter of the invention avoids the use of templates or even a force-fitting ancillary device for driving in and putting in place said shutter.

L'invention évite également les risques du fuite et de migration de l'obturateur dans le canal intra-médullaire, lors de la mise en pression du ciment chirurgical. Les contraintes mécaniques de l'obturateur en expansion latérale sont en effet supérieures à celles de la pression exercée par le ciment. The invention also avoids the risks of leakage and migration of the obturator in the intramedullary canal, when the surgical cement is pressurized. The mechanical stresses of the lateral expansion shutter are in fact greater than those of the pressure exerted by the cement.

En effet, dans le cas de canal médullaire trop rectiligne ou avec un faible rétrécissement du fut dans la partie diaphysaire, par exemple le canal médullaire huméral, les obturateurs accrochent mal et le risque de migration lors de la mise en pression du ciment demeure important et laisse aléatoire la bonne fixation de l'implant.  In fact, in the case of a medullary canal that is too straight or with a slight narrowing of the barrel in the diaphyseal part, for example the humeral medullary canal, the obturators hang poorly and the risk of migration during the pressurization of the cement remains high and leaves random the correct fixation of the implant.

En outre, la mise en oeuvre de l'invention n'exige qu'un seul temps opératoire, l'expansion latérale, l'adéquation avec la cavité osseuse et la tenue mécanique de l'élément souple étant réalisées simultanément. In addition, the implementation of the invention requires only one operating time, the lateral expansion, the adequacy with the bone cavity and the mechanical strength of the flexible element being carried out simultaneously.

Le ou les matériaux biocompatibles résorbables constituant l'obturateur de l'invention peuvent être choisis parmi les produits suivants: le collagène, l'alginate, le dextran, la caséine, ou une combinaison de ces produits. Une rigidité plus ou moins grande de ces matériaux est obtenue en modifiant leur composition, notamment leur teneur en eau. The absorbable biocompatible material or materials constituting the obturator of the invention can be chosen from the following products: collagen, alginate, dextran, casein, or a combination of these products. More or less rigidity of these materials is obtained by modifying their composition, in particular their water content.

La description qui va suivre en regard des dessins annexés, donnés à titre d'exemples non limitatifs, fera bien comprendre en quoi consiste l'invention et comment elle peut être réalisée. The description which follows with reference to the appended drawings, given by way of nonlimiting examples, will make it clear what the invention consists of and how it can be implemented.

La figure 3a est une vue de côté d'un troisième mode de réalisation d'un obturateur conforme à l'invention. Figure 3a is a side view of a third embodiment of a shutter according to the invention.

Les figures 3b et 3c sont des vues de côté montrant l'obturateur de la figure 3a à l'intérieur d'une cavité osseuse respectivement avant et après expansion latérale. Figures 3b and 3c are side views showing the obturator of Figure 3a inside a bone cavity before and after lateral expansion respectively.

La figure 1 montre en vue de côté un obturateur 100 pour cavités osseuses, notamment pour la pose avec ciment chirurgical d'une prothèse ou d'un implant en chirurgie orthopédique. Cet obturateur est globalement réalisé en matériaux biocompatibles résorbables, tels que ceux mentionnés précédemment. Figure 1 shows a side view of a shutter 100 for bone cavities, in particular for the installation with surgical cement of a prosthesis or an implant in orthopedic surgery. This shutter is generally made of absorbable biocompatible materials, such as those mentioned above.

L'obturateur 100 de la figure 1 comporte un élément 110 en matériau souple qui se présente comme un composant de forme sensiblement cylindrique, traversé par un axe 120 en matériau rigide qui peut être de même nature que ledit matériau souple mais de concentration en eau différente. The shutter 100 of FIG. 1 comprises an element 110 of flexible material which is presented as a component of substantially cylindrical shape, crossed by an axis 120 of rigid material which may be of the same nature as said flexible material but with a different water concentration .

L'axe 120 est muni d'une pluralité de crans 121 de retenue et porte, à une première extrémité, une butée 122 fixe pour ledit composant souple 110. The axis 120 is provided with a plurality of retaining notches 121 and carries, at a first end, a stop 122 fixed for said flexible component 110.

Comme on peut le voir sur la figure 1, le composant 110 est surmonté, à une deuxième extrémité de l'axe 120 rigide, par une rondelle 130 de verrouillage, également en matériau rigide, qui peut être d'ailleurs le même que celui de l'axe 120. Cette rondelle 130 de verrouillage est destinée à coopérer avec lesdits crans 121 de retenue lorsque le composant 110 souple est soumis à un effort de compression, représenté par les deux flèches
F, appliqué sur la rondelle 130 de verrouillage.As can be seen in FIG. 1, the component 110 is surmounted, at a second end of the rigid axis 120, by a locking washer 130, also made of rigid material, which can moreover be the same as that of the axis 120. This locking washer 130 is intended to cooperate with said retaining notches 121 when the flexible component 110 is subjected to a compressive force, represented by the two arrows
F, applied to the locking washer 130.

Ainsi, sous l'action de l'effort F de compression, ladite rondelle 130 de verrouillage appuie sur le composant souple 120 qui subit de ce fait une expansion latérale par déformation dans direction montrée par les flèches F'. Cette expansion latérale est apte à remplir la cavité osseuse 10 dans laquelle l'obturateur 100 est placé, et d'y produire une adéquation complète du composant souple 110 contre les parois 11 desdites cavités par obturation forcée. Thus, under the action of the compression force F, said locking washer 130 presses on the flexible component 120 which therefore undergoes lateral expansion by deformation in the direction shown by the arrows F '. This lateral expansion is able to fill the bone cavity 10 in which the obturator 100 is placed, and to produce there a complete adequacy of the flexible component 110 against the walls 11 of said cavities by forced obturation.

L'expansion latérale du composant 110 peut être réglée, en fonction de la section de la cavité 10 à obturer, à l'aide des crans 121 de retenue qui empêchent la rondelle 130 de verrouillage, et donc le composant
110, de remonter le long de l'axe 120 sous l'action de
la force élastique de rappel développée par ledit
composant souple 110 lorsqu'il est comprimé.The lateral expansion of the component 110 can be adjusted, depending on the section of the cavity 10 to be closed, using retaining notches 121 which prevent the washer 130 from locking, and therefore the component
110, to go up along the axis 120 under the action of
the elastic restoring force developed by said
flexible component 110 when compressed.

A l'aide d'un ancillaire, non représenté, le
chirurgien peut déformer à volonté le composant souple
110 jusqu'à ce qu'il estime que l'obturation de la
cavité osseuse 10 est complète. Le composant 110 est
alors maintenu dans cette position grâce à la
coopération entre la rondelle 130 de verrouillage et le
cran de retenue immédiatement supérieur.Using an ancillary, not shown, the
surgeon can deform the flexible component at will
110 until he feels that shuttering the
bone cavity 10 is complete. Component 110 is
then kept in this position thanks to the
cooperation between the locking washer 130 and the
immediately higher retaining notch.

Dans l'exemple de réalisation des figures 2a, 2b et
2c, ledit élément en matériau souple est une enveloppe
210 fermée par une vanne 220 rigide permettant
l'introduction, à l'intérieur de ladite enveloppe 210,
d'un matériau 230 fluide sous pression. Celui-ci provoque une expansion latérale de l'obturateur 200 dans
le sens des flèches F' par gonflement de l'enveloppe
souple 210 qui vient alors en appui forcé contre la paroi intérieure 11 de la cavité osseuse 10.In the embodiment of Figures 2a, 2b and
2c, said element made of flexible material is an envelope
210 closed by a rigid valve 220 allowing
the introduction, inside said envelope 210,
of a material 230 fluid under pressure. This causes lateral expansion of the shutter 200 in
the direction of the arrows F 'by swelling of the envelope
flexible 210 which then comes into forced abutment against the internal wall 11 of the bone cavity 10.

Enfin, selon le mode de réalisation des figures 3a,
3b et 3c, ledit élément en matériau souple est un bouchon 300 réalisé en un matériau de reprise de forme apte à recouvrir son volume initial notamment par
expansion latérale après qu'il ait été mis en compression.Finally, according to the embodiment of FIGS. 3a,
3b and 3c, said element made of flexible material is a plug 300 made of a material for resumption of shape capable of covering its initial volume in particular by
lateral expansion after it has been compressed.

Ledit matériau de reprise de forme peut être par exemple du collagène alvéolé. Said return-to-shape material may for example be honeycomb collagen.

La pose de l'obturateur 300 consiste à comprimer latéralement le matériau de reprise de forme, à introduire le bouchon 300 ainsi comprimé à l'intérieur de la cavité osseuse 10, puis à laisser le bouchon 300 ,reprendre sa forme initiale, ce qui produit une obturation forcée de la cavité osseuse 10 à condition toutefois que la section initiale du bouchon 300 soit plus soit plus grande que celle de ladite cavité.  The fitting of the obturator 300 consists in laterally compressing the shape recovery material, in introducing the plug 300 thus compressed inside the bone cavity 10, then in leaving the plug 300, resuming its initial shape, which produces forced closure of the bone cavity 10 provided, however, that the initial section of the plug 300 is greater or greater than that of said cavity.
