DISPOSITIF DE FIXATION POUR PROTHESE MOBILE COMPORTANT UN IMPLANT SOUS CUTANE ET UNE PARTIE EXTERNE AMOVIBLE FIXING DEVICE FOR MOBILE PROSTHESIS COMPRISING A CUTANEOUS IMPLANT AND A REMOVABLE EXTERNAL PART
La présente invention concerne un dispositif de fixation pour prothèses mobiles en deux parties distinctes, l'une placée sous la peau du patient appelée "implant", l'autre fixée sur une prothèse mobile appelée "pont d'attache". Ce dispositif permet d'appliquer facilement sur le patient sans fixation définitive, toute prothèse médicale ou paramédicale et toute prothèse capillaire, avec toutes les garanties d'hygiène et de sécurité. Le dispositif selon l'invention a pour objet de remédier aux inconvénients inhérents aux autres procédés de fixations mobiles, l'implant étant souple et recouvert de métal précieux et/ou d'un polymère, pour éviter tout risque de rejet par l'organisme du patient. De la même façon, le pont d'attache es lui aussi recouvert d'un métal précieux et/ou d'un élasto ère et d'un coussin hypoallergique pour éviter tout risque dermatologique. Le nombre, la forme et le positionnement du dispositif sont suffisants pour assurer une fixation parfaite de la prothèse sans risque d'arrachement accidentel, alors que la force d'attraction et la surface d'appui des pièce en contact sont calculées pour ne pas comprimer exagérément la peau. Le dispositif faisant l'objet du brevet présente une nette amélioration des technologies actuelles de fixations mobiles, car tout en offrant les avantages d'une fixation efficace, sécurisante, pratique et saine, il permet la séparation volontaire instantanée des deux parties pour les opérations d'hygiène courante.The present invention relates to a fixing device for mobile prostheses in two distinct parts, one placed under the skin of the patient called "implant", the other fixed on a mobile prosthesis called "attachment bridge".

D'autres caractéristiques et avantages de l'invention seront mieux compris à la lecture de la descriptionqui va suivredes différents modes de réalisation et en se référant aux dessins annexés, sur lesquels on représente:Other characteristics and advantages of the invention will be better understood on reading the description which follows of the various embodiments and with reference to the appended drawings, in which:
-FIG 1- Implant en forme de disque souple 1, composé d'un noyau central 2 en métal ferreux, enfermé entre deux enveloppes souples 3 et 4 matricées en métal précieux ou recouvertes d'un plaquage résistant en métal précieux et percé d'orifices périphériques 5. Le disque 1 est soudé par un cordon étanche, afin que le noyau central 2 noyé entre les deux enveloppes 3 et 4, résiste indéfiniment à la corrosion et aux agents chimiques de l'organisme. Sa forme et sa souplesse permettent, une fois son implantation sous-cutanée et grâce à sa grande stabilité dimentionnelle, d'obtenir un grand confort pour le patient. A cet effet, les orifices 5 percés de part en part du disque 1, sont destinés à améliorer le blocage de l'implant, en permettant le développement des fibres collagènes du tissu conjonctif, supprimant ainsi les risques éventuels de déplacement. -FIG 2- Coupe de l'implant montrant le disque 1, le noyau central 2, les deux enveloppes 3 et 4 et les orifices périphériques 5. Pendant la phase de soudage des deux enveloppes 3 et 4 avec un cordon de soudure, on utilise un voile de carbone qui évite la fusion des métaux, qui restent ainsi bien séparés. Cette particularité de l'usinage présente l'avantage d'exclure tout risque de porosité des enveloppes 3 et 4 en métal précieux, et donne une finition laquée du disque 1, indispensable à son utilisation sous-cutanée.-FIG 1- Implant in the form of a flexible disc 1, composed of a central core 2 of ferrous metal, enclosed between two flexible envelopes 3 and 4 stamped in precious metal or covered with a resistant plating in precious metal and pierced with orifices peripherals 5. The disc 1 is welded by a waterproof cord, so that the central core 2 embedded between the two envelopes 3 and 4, indefinitely resists corrosion and chemical agents of the organism. Its shape and flexibility allow, once its implantation subcutaneous and thanks to its great dimensional stability, to obtain great comfort for the patient. To this end, the orifices 5 drilled right through the disc 1 are intended to improve the blocking of the implant, by allowing the development of collagen fibers of the connective tissue, thus eliminating the possible risks of displacement. -FIG 2- Section of the implant showing the disc 1, the central core 2, the two envelopes 3 and 4 and the peripheral orifices 5. During the welding phase of the two envelopes 3 and 4 with a weld bead, we use a carbon veil which avoids the fusion of metals, which thus remain well separated. This particularity of the machining has the advantage of excluding any risk of porosity of the envelopes 3 and 4 in precious metal, and gives a lacquered finish to the disc 1, essential for its subcutaneous use.
Il est bien entendu que toutes les parties du disque 1 et notamment les angles et rebords, sont adoucis afin de garantir le maximum de confort au porteur. -FIG 3- Implant en forme de plaque souple 6, formée d'un noyau central 2 en métal ferreux, enfermé dans deux enveloppes en élastomère 7 et 8. Cette plaque qui peut avoir la forme définie sur la figure 3 ou toute autre forme, comporte un orifice d'ancrage 9 et un marquage de découpe 10, destinés au chirurgien. Cet implant est fabriqué en bande continue, soit à froid en employant des bandes d'élastomères préformées type si1icône réticulé avec interposition du noyau central 2 et collage avec colle silicone monocomposant et pressage, soit à chaud, en employant des bandes d'élastomère type silicone non réticulé, avec interposition du noyau central 2, pressage et chauffage entre 130 et 150°C jusqu'à réticulation de 1'élastomère par vulcanisation Dans ces deux types de mise en oeuvre du produit, il faut traiter préalablement le noyau central 2 avec un primaire d'adhésion, pour rendre l'ensemble parfaitement homogène. Le perçage de l'orifice d'ancrage 9 et le marquage de découpe 10, sont effectués ensuite directement sur la bande d'implants. -FIG 4- Coupe de l'implant montrant le noyau central 2, et les deux enveloppes en élastomère 7 et 8. -FIG 5- Implant en forme de bande mince souple 12 en métal ferreux recouvert soit d'un plaquage en métal précieux, soit d'un revêtement en élastomère résistant aux agents chimiques de l'organisme. Cet implant en fer malléable est facilement 5 formable à la main, pour épouser les contours du crâne du patient. -FIG 6- Coupe de l'implant en forme de bande souple mince en métal ferreux 12.It is understood that all the parts of the disc 1 and in particular the angles and edges, are softened in order to guarantee maximum comfort for the wearer. -FIG 3- Implant in the form of a flexible plate 6, formed of a central core 2 of ferrous metal, enclosed in two elastomer envelopes 7 and 8. This plate which may have the shape defined in FIG. 3 or any other shape, has an anchoring hole 9 and a cutout marking 10, intended for the surgeon. This implant is manufactured in a continuous band, either cold using bands of preformed elastomers type si1icon crosslinked with interposition of the central core 2 and bonding with single-component silicone glue and pressing, or hot, using bands of elastomer type silicone uncrosslinked, with interposition of the central core 2, pressing and heating between 130 and 150 ° C until crosslinking of the elastomer by vulcanization In these two types of application of the product, the central core 2 must be treated beforehand adhesion primer, to make the whole perfectly homogeneous. The drilling of the anchoring hole 9 and the cutting marking 10 are then carried out directly on the implant strip. -FIG 4- Section of the implant showing the central core 2, and the two elastomer envelopes 7 and 8. -FIG 5- Implant in the form of a flexible thin strip 12 of ferrous metal covered either with a precious metal plating or with an elastomer coating resistant to the chemical agents of the organism. This malleable iron implant is easily formable by hand to conform to the contours of the patient's skull. -FIG 6- Cut of the implant in the form of a thin flexible strip of ferrous metal 12.
Tous ces implants peuvent être également fabriqués suivant 0 d'autres principes et notamment par l'application d'un traitement de surface au collagène destiné à favoriser la prolifération des fibroblastes et des yofibroblastes, qui vont s'orienter selon des lignes parallèles de tension mécanique et selon des lignes de pression. 5 -FIG 7- Représentation de la disposition géographique sur un crâne, des implants en bande mince souple 12. -FIG 8- Représentation de la disposition géographique des implants recouverts de métal précieux 1, sur la tête 11 du patient. -FIG 9- Représentation de la disposition géographique de bandes d'implants recouverts d'élastomère.6 sur la tête 11. -FIG 10- Représentation d'un pont d'attache en forme de plaque ou de bague 13, composé d'un micro-aimant sanarium cobalt fer et/ou toute autre matière magnétique.All these implants can also be manufactured according to other principles and in particular by the application of a collagen surface treatment intended to promote the proliferation of fibroblasts and yofibroblasts, which will orient themselves along parallel lines of mechanical tension. and along pressure lines. 5 -FIG 7- Representation of the geographic arrangement on a skull, flexible thin strip implants 12. -FIG 8- Representation of the geographic arrangement of implants covered with precious metal 1, on the patient's head 11. -FIG 9- Representation of the geographic arrangement of bands of implants covered with elastomer. 6 on the head 11. -FIG 10- Representation of an attachment bridge in the form of a plate or ring 13, composed of a micro-magnet sanarium cobalt iron and / or any other magnetic material.
Ce pont d'attache 13 est fixé soit directement soit indirectement sur la prothèse médicale ou para-médicale, ou sur la monture de la prothèse capillaire portant les cheveux naturels ou synthétique par l'intermédiaire d'un système mécanique de fixation tel que: fil de couture, agrafage, bouton pression ou bande adhésive, ou bande accrocheuse On peut intercaler entre le pont d'attache et la peau pour des raisons de confort supplémentaire, un coussin hypoallergique. -FIG 11- Coupe du pont d'attache en forme de bague 13. -FIG 12- Coupe du pont d'attache 13 en forme de bague, comportant un fond 14 destiné à diminuer les risques de déformation du contact entre peau et prothèse mobile. -FIG 13- Pont d'attache en forme de bande souple 15, constituée de lamelles magnétiques 16 collées, et portant des trous longitudinaux 17 destiné à l'accrochage sur la monture de la prothèse mobile. -FIG14- Pont d'attache en forme de bandé souple15 , constituée d'un revêtement contenant des particules métalliques magnétiques18, et percée de trous de montage sur les montures des prothèses 17.

On peut aussi utiliser avec ce système des modes de fixation, tels que: fil de couture, agrafage, bouton pression ou bande..adhésive.This attachment bridge 13 is fixed either directly or indirectly on the medical or paramedical prosthesis, or on the frame of the capillary prosthesis carrying natural or synthetic hair by means of a mechanical fixing system such as: wire sewing, stapling, press stud or adhesive strip, or catchy strip A hypoallergenic cushion can be inserted between the attachment bridge and the skin for reasons of additional comfort. -FIG 11- Cross section of the attachment bridge in the form of a ring 13. -FIG 12- Cross section of the attachment bridge 13 in the form of a ring, comprising a bottom 14 intended to reduce the risk of deformation of the contact between the skin and mobile prosthesis . -FIG 13- Attachment bridge in the form of flexible strip 15, consisting of magnetic strips 16 glued, and carrying longitudinal holes 17 intended for attachment to the frame of the mobile prosthesis. -FIG14- Attachment bridge in the form of a flexible band15, consisting of a coating containing magnetic metallic particles18, and pierced with mounting holes on the mounts of the prostheses 17. These two types of flexible attachment bridge are easily exploited tables, the technician being able to cut his flexible strip 15 directly to the desired length, before it is placed on the frame. It is also possible to use with this system fixing methods, such as: sewing thread, stapling, snap button or adhesive tape.
Le principe du dispositif est simple. Les implants l 6 et 12 posés sous la peau du patient par le chirurgien, après cicatrisation définitive des incisions, la présentation des ponts d'attache 13 en face des implants peut être effectuée. Par simple effet de magnétisme les deux parties vont se trouver attirées l'une contre l'autre, assurant ainsi un contact permanent. Les prothèses se trouvant fixées aux ponts d'attache vont se trouver positionner durablement, jusqu'à arrachement volontaire du patient pour les soins d'usage. La pose des implants par un chirurgien, ne nécessite qu'une intervention bénigne sous anesthésie locale, aucun phénomène de rejet n'étant à craindre compte tenu de la qualité des matières employées, don la pureté doit être,voisine de 100%. On peut par exemple comme nous l'avons déjà indiqué, utiliser un dispositif identique pour résoudre des problèmes.de fixation externe d'appareils médicaux ou para-médicaux, comme des poches en matière plastique, des appareils d'assistance médicale, des intraveineuses portables avec pompe doseuse d'injection de produits actifs, des comprimés médicamenteux percés au "laser" et des réserves à membrane semi-perméable qui diffusent en continu le traitement médical du malade.The principle of the device is simple. The implants 6 and 12 placed under the patient's skin by the surgeon, after final healing of the incisions, the presentation of the attachment bridges 13 in front of the implants can be carried out. By simple effect of magnetism the two parts will be attracted one against the other, thus ensuring a permanent contact. The prostheses being fixed to the attachment bridges will be positioned durably, until voluntary removal of the patient for the usual care. The placement of the implants by a surgeon, requires only a benign intervention under local anesthesia, no rejection phenomenon being to be feared taking into account the quality of the materials used, therefore the purity must be close to 100%. We can for example, as we have already indicated, use an identical device to solve problems of external fixation of medical or paramedical devices, such as plastic bags, medical assistance devices, portable intravenous with dosing pump for injection of active products, medicated tablets pierced by "laser" and reserves with semi-permeable membrane which continuously diffuse the medical treatment of the patient.
L'emploi d'un tel dispositif est intéressant pour le monde médical moderne, car cette.technique applicable pratiquement sur n'importe quelle partie du corps humain, permet au patient devant subir des traitements de longue durée comme les traitements hormonaux par exemple, et/ou au patient traité sur un organe cible, de limiter voire d'éliminer tout risque secondaire sur l'organisme. De plus cette technologie supprime pour le malade, l'usage toujours contraignant des bandes dermiques, des ceintures ou des sangles. Enfin l'invention n'est nullement limitée aux moyens constituants des équivalents techniques ainsi que leurs combinaisons, mais elle couvre également des modes de réalisation qui n'en différeraient que par des détails, par des variantes d'exécution ou par l'utilisation de moyens identiques.The use of such a device is interesting for the modern medical world, because this . technique applicable to practically any part of the human body, allows the patient to undergo long-term treatments such as hormonal treatments for example, and / or the patient treated on a target organ, to limit or even eliminate any secondary risk on the organism. In addition, this technology eliminates for the patient, the always binding use of dermal bands, belts or straps. Finally, the invention is in no way limited to the means constituting technical equivalents and their combinations, but it also covers embodiments which would differ only in details, in variant embodiments or in the use of identical means.
On voit ainsi, que de nombreux types de montage peuvent être retenus.It is thus seen, that many types of assembly can be retained.
Un gabarit de positionnement est fourni au chirurgien en fonction de la surface à couvrir, pour qu'il puisse disposer facilement les implants sur le patient. Le chirurgien peut donner une radiographie de positionnement des implants au prothésiste, pour que celui-ci repère facilement la disposition des ponts d'attache 16 sur les montures.A positioning template is provided to the surgeon according to the surface to be covered, so that he can easily place the implants on the patient. The surgeon can give an implant positioning radiography to the prosthetist, so that the latter can easily identify the arrangement of the attachment bridges 16 on the frames.
Dans un autre mode de réalisation, on peut prévoir de fixer les implants en métal ferreux directement sur la table osseuse du patient. II va de soi que l'utilisation et la mise en oeuvre du dispositif n'est pa limitée aux moyens exposés dans le cadre des revendications qui suivent, si ceux-ci sont exécutés suivant son esprit, notamment en ce qui concerne le système de fixation magnétique et/ou la forme des pièces décrites dans le dispositif. In another embodiment, provision may be made to fix the ferrous metal implants directly on the patient's bone table. It goes without saying that the use and implementation of the device is not limited to the means set out in the context of the claims which follow, if these are carried out according to the spirit, in particular as regards the fixing system magnetic and / or the shape of the parts described in the device.
