Abstract

The prosthesis consists of a plate of synthetic biocompatible material in the form of non-woven synthetic fibres with an asymmetrical medial cavity (1), the base (4) of which is offset relative to its centre (3). The rear edge (2) of the plate is raised by about 2 mm relative to its front edge, and its surface in contact with the eyeball is coated with a smooth and supple material. The plate can vary in thickness between 1.5 and 2.5 mm, and can be used as part of an assembly of plates to adjust the height of the eye.

Description

PROTHESE <B>ORBITALE</B> présente invention concerne une prothèse orbitale.  ORBITAL PROSTHESIS </ B> The present invention relates to an orbital prosthesis.

est connu dans l'état de la technique de procéder à la reconstruction des planchers orbite après des gros fracas de la face par une technique consistant à positionner une plaque en métal sous 1'#i1. Cette plaque est formée manuellement par le chirurgien ce qui est difficile mettre en #uvre et conduit à des reconstructions approximatives. It is known in the state of the art to proceed with the reconstruction of the orbiting floors after a big crash of the face by a technique consisting in positioning a metal plate under FIG. This plate is manually formed by the surgeon which is difficult to implement and leads to approximate reconstructions.

'invention vise à remédier à cet inconvénient en proposant une prothèse dont la forme est adaptée à la reconstruc ion orbitale, et évitant d'éventuelles formations de phénomènes électros iques ou radioélectriques. The invention aims to remedy this disadvantage by proposing a prosthesis whose shape is adapted to orbital reconstruction, and avoiding any formation of electro or radioelectric phenomena.

A cet effet, l'invention concerne selon son acception la plus générale une prothèse chirurgicale pour la formation d'un plancher d'orbite caracterisé en ce qu'elle formée par une plaque en un matériau biocompatible synthétique présentent une cavité médiane. For this purpose, the invention relates, in its most general sense, to a surgical prosthesis for the formation of an orbital floor characterized in that it is formed by a plate made of a synthetic biocompatible material having a median cavity.

préférence, la cavité est dissymétrique. Selon un mode de réalisation préféré, le bord arrière de plaque est surélevé par rapport au bord avant de la plaque. La surélévation est d'environ mm. preferably, the cavity is asymmetrical. According to a preferred embodiment, the trailing edge of the plate is elevated with respect to the front edge of the plate. The elevation is about mm.

Avantageusement, la plaque peut être réalisée suivant différentes épaisseurs allant de 1, millimètres à 2,5 millimètres ou plus. Advantageously, the plate can be made in different thicknesses ranging from 1 millimeter to 2.5 millimeters or more.

Selon une variante préférée, plaque est réalisée en un matériau synthétique de fibres non tissées. Cette plaque réalisée dans un tel matériau peut avantageusement être découpée pendant l'intervention afin de s'adapter à l'anatomie du patient. According to a preferred variant, plate is made of a synthetic material of non-woven fibers. This plate made of such a material can advantageously be cut during the procedure in order to adapt to the anatomy of the patient.

L'invention sera mieux comprise à la lecture la description qui suit, se référant à un exemple limitatif de réalisation et aux figures annexées où - la figure 1 représente une vue schématique d'une prothèse selon un plan de coupe transversal ; - la figure 2 représente une vue de dessus d'une telle prothèse. The invention will be better understood on reading the description which follows, referring to a limiting embodiment and to the appended figures in which: - Figure 1 shows a schematic view of a prosthesis according to a transverse sectional plane; - Figure 2 shows a top view of such a prosthesis.

La prothèse selon l'invention est formée une plaque de matériau synthétique non tissé de différentes épaisseurs allant de 1,5 mm à 2,5 mm. The prosthesis according to the invention is formed a plate of nonwoven synthetic material of different thicknesses ranging from 1.5 mm to 2.5 mm.

Le fond (4) de la cavité (1) est décalé rapport au centre (3) de la plaque (1), de forme oblongue. Les parois de la cavité présentent une pente plus importante vers l'arrière (5). The bottom (4) of the cavity (1) is offset relative to the center (3) of the plate (1), oblong shape. The walls of the cavity have a greater slope towards the rear (5).

La plaque présente en vue de dessus une forme sensiblement ovale, avec une cavité (1) de section sensiblement circulaire, comme représentée schématiquement en figure par des courbes de niveau concentriques. The plate has a top view in a substantially oval shape, with a cavity (1) of substantially circular section, as shown schematically in the figure by concentric contour lines.

Le matériau synthétique permet d'éviter d'éventuels problèmes de phénomènes électrique lors séances de radiothérapie. The synthetic material makes it possible to avoid possible problems of electrical phenomena during radiotherapy sessions.

Les prothèses peuvent être empilées les unes dans les autres afin de permettre une adaptation de position 1'#i1 et éviter les problèmes de vision occasionnées par un décalage de hauteur entre les deux yeux. The prostheses can be stacked into each other to allow for positional adjustment and avoid vision problems caused by a height shift between the two eyes.

coté recevant 1'#i1 est revêtu d'une couche de silicone ou d'un matériau lisse et souple. Eventuellement les deux faces de la plaque sont recouvertes d'un produit évitant l'irritation.receiving side 1 '# i1 is coated with a layer of silicone or a smooth and flexible material. Optionally both sides of the plate are covered with a product avoiding irritation.
