Abstract

A sheet with a fibrillar structure has a rough surface, close to the natural conjunctive structure, and is so formed of a bio-compatible polymer, and may be impregnated with a very small amt. of a medical elastomer or plastomer.

Description

L'invention concerne une plaque de reconstitution pour le domaine de la chirurgie. The invention relates to a reconstruction plate for the field of surgery.

Dans les interventions chirurgicales touchant ou approchant le cerveau ou la moelle épinière, il faut protéger ou reconstituer les enveloppes de ces tissus dits nobles et, en particulier, la membrane extérieure appelée dure-mère contre la fibrose cicatricielle post clururgicale. Dans ce but, il est habituel d'utiliser un morceau de dure-mère prélevé sur cadavre, traité et stérilisé, placé au contact direct des tissus nobles par le chirurgien.Hors ce matériau présente plusieurs inconvénients : il est coûteux du fait de sa provenance humaine et des traitements nécessaires, et surtout peut transmettre des maladies (sida, hépatite, Creutzfeldt-jakob...). Ces maladies ne sont pas forcément détectables par les tests de laboratoire : il existe des périodes de latence pendant lesquelles les porteurs de ces maladies sont déjà contagieux, c'est dire peuvent transmettre la maladie, et où les tests de laboratoire ne sont pas encore positifs. In surgical procedures touching or approaching the brain or the spinal cord, it is necessary to protect or reconstitute the envelopes of these so-called noble tissues and, in particular, the outer membrane called dura mater against postclururgical scar fibrosis. For this purpose, it is usual to use a piece of dura mater taken from a corpse, treated and sterilized, placed in direct contact with the noble tissues by the surgeon. However, this material has several disadvantages: it is expensive because of its origin human and necessary treatments, and above all can transmit diseases (AIDS, hepatitis, Creutzfeldt-jakob ...). These diseases are not necessarily detectable by laboratory tests: there are latency periods during which the carriers of these diseases are already contagious, that is to say can transmit the disease, and where laboratory tests are not yet positive .

L'invention a pour objet d'éviter ces risques de transmission de maladies par les tissus d'origine humaine ou animale, en réalisant une plaque présentant une structure fibrillaire proche de la structure conjonctive naturelle, fabriquée en matériau synthétique, donc exempte de maladie afin de protéger les tissus nobles contre la fibrose cicatricielle. The object of the invention is to avoid these risks of transmission of diseases by tissues of human or animal origin, by producing a plate having a fibrillar structure close to the natural connective structure, made of synthetic material, therefore free of disease so protect noble tissue against scar fibrosis.

L'invention consiste à utiliser un tissu textile poreux de construction serrée, que l'on peut imprégner d'une très faible quantité d'un élastomère médical afin de rendre les fils du tissu plus lisses, moins perméables et non traumatisants pour les tissus mais aptes à laisser passer les fluides biologiques. The invention consists in using a porous textile fabric of tight construction, which can be impregnated with a very small amount of a medical elastomer in order to make the threads of the fabric smoother, less permeable and non-traumatic for the tissues but suitable for letting biological fluids through.

On peut d'ailleurs améliorer l'aspect lisse en réalisant sur une face du produit un côté totalement lisse par dépôt d'une couche uniforme d'élastomère et en laissant l'autre côté plus rugueux pour permettre sa réhabitation par les tissus de l'hôte. Le côté lisse sera placé en regard des tissus nobles et le côté rugueux en regard des tissus conjonctifs ou musculaires pour permettre la réhabitation tissulaire. We can also improve the smooth appearance by making a completely smooth side on one side of the product by depositing a uniform layer of elastomer and leaving the other side rougher to allow it to be re-used by the tissues of the host. The smooth side will be placed opposite the noble tissues and the rough side opposite the connective or muscular tissues to allow tissue rehabitation.

Le tissu textile peut être un tricot, un tissu serré, ou de façon plus satisfaisante, un produit dit non tissé réalisé en enchevêtrant des fils par technique de jet d'air, par exemple, ou par soudure fil à fil. Ces produits présentent l'avantage d'une structure fibrillaire proche de la structure conjonctive naturelle. The textile fabric can be a knitted fabric, a tight fabric, or more satisfactorily, a so-called non-woven product produced by entangling threads by air jet technique, for example, or by thread-to-thread welding. These products have the advantage of a fibrillar structure close to the natural connective structure.

A titre d'exemple de réalisation d'une plaque selon l'invention, on utilise un produit non tissé 100% polyester. Ce produit, après nettoyage par les techniques connues, est imprégné avec une silicone de grade médical par trempage puis égouttage et polymérisation à l'étuve. As an exemplary embodiment of a plate according to the invention, a 100% polyester nonwoven product is used. This product, after cleaning by known techniques, is impregnated with a medical grade silicone by soaking then draining and polymerization in an oven.

La plaque obtenue est légèrement perméable du fait de la faible quantité de silicone, très souple et pouvant se déformer facilement pour les mêmes raisons; elle permet le passage des fluides biologiques. The plate obtained is slightly permeable due to the small amount of silicone, very flexible and which can easily deform for the same reasons; it allows the passage of biological fluids.

Selon un mode préférentiel de réalisation de l'invention, on a déposé 8mg/cm2 d'élastomère sur un non tissé de 0,45 mm d'épaisseur pesant 8mg/cm2. According to a preferred embodiment of the invention, 8 mg / cm 2 of elastomer has been deposited on a 0.45 mm thick nonwoven weighing 8 mg / cm 2.

Si on désire obtenir une face parfaitement lisse, on réalise, avant polymérisation, le dépôt par calandrage d'une fine couche de silicone sur une face du produit, l'ensemble étant ensuite polymérisé à l'étuve. A partir d'un non tissé de 0,45 mm d'épaisseur initiale, on obtient après imprégnation et calandrage d'une couche de silicone sur une face un produit final de 0,60 mm d'épaisseur environ. If it is desired to obtain a perfectly smooth face, before coating, polymerization is carried out by calendering a thin layer of silicone on one side of the product, the assembly then being polymerized in an oven. From a non-woven fabric with an initial thickness of 0.45 mm, a final product with a thickness of approximately 0.60 mm is obtained after impregnation and calendering of a layer of silicone on one side.

L'exemple de réalisation avec un non tissé peut, bien entendu, être étendu à tout type de construction textile, tricot de tout type, tissu, voire tresse plate. Les épaisseurs et masse des tissus, les quantités déposées peuvent varier en fonction des tissus et des applications. The exemplary embodiment with a nonwoven can, of course, be extended to any type of textile construction, knitting of any type, fabric, or even flat braid. The thicknesses and mass of the fabrics, the quantities deposited can vary depending on the fabrics and applications.

Le matériau du tissu ayant une structure fibrillaire proche de la structure conjonctive naturelle est un polymère biocompatible qui peut être du polyester, du polyamide, du polypropylène, du polytétrafluoroéthylène ou tout matériau biocompatible, très souple et non traumatisant pour les tissus. The material of the tissue having a fibrillar structure close to the natural connective structure is a biocompatible polymer which can be polyester, polyamide, polypropylene, polytetrafluoroethylene or any biocompatible material, very flexible and non-traumatic for the tissues.

L'élastomère biocompatible utilisé peut être de la silicone, du polyuréthanne ou tout autre élastomère biocompatible résorbable ou non résorbable. The biocompatible elastomer used can be silicone, polyurethane or any other absorbable or non-absorbable biocompatible elastomer.

Un plastomère peut également être utilisé pour imprégner le tissu et particulièrement le polyamide, polychlorure de vinyle, polyester, polyuréthanne ou polyoléfine. A plastomer can also be used to impregnate the fabric and in particular polyamide, polyvinyl chloride, polyester, polyurethane or polyolefin.

L'application décrit une plaque pour les traitements de neurochirurgie touchant ou approchant la dure mère, mais l'invention permet de réaliser des plaques pour d'autres interventions : plaques de renfort pour la chirurgie orthopédique, chirurgie viscérale, dont le traitement des hernies, chirurgie gynécologique, chirurgie cardiaque et vasculaire et de façon générale toutes les applications médicales et vétérinaires bénéficiant de plaques à structure fibrillaire proche de la structure conjonctive naturelle, imprégnées d'une très faible quantité d'un élastomère médical afin de rendre les fils du tissu plus lisses, moins perméables et non traumatisants pour les tissus. The application describes a plate for neurosurgical treatments touching or approaching the dura mater, but the invention makes it possible to produce plates for other interventions: reinforcement plates for orthopedic surgery, visceral surgery, including the treatment of hernias, gynecological surgery, cardiac and vascular surgery and in general all medical and veterinary applications benefiting from plates with fibrillar structure close to the natural connective structure, impregnated with a very small amount of a medical elastomer in order to make the threads of the tissue more smooth, less permeable and non-traumatic for the tissues.

Selon un autre mode de réalisation de l'invention, on imprègne un produit textile tubulaire afin d'obtenir une prothèse vasculaire souple et élastique, mais gardant sa forme tubulaire et légèrement perméable pour laisser passer les fluides biologiques.  According to another embodiment of the invention, a tubular textile product is impregnated in order to obtain a flexible and elastic vascular prosthesis, but retaining its tubular shape and slightly permeable to let the biological fluids pass.
