An external prosthesis (40) and a method for affixing the prosthesis to the user by means of compliantly housed magnets (30) interacting with surgical steel implants (10) inserted beneath the skin of the user. The implants are surgical steel buttons coated with methylmethacrylate to avoid the release of corrosion products and silastic, a biocompatible material. The implant (10) is inserted beneath the patient's skin along with a biocompatible mesh material (15) to provide additional strength. A flexible carrier (21) is formed with a hollow cylindrical shape to allow a magnet (30) to move freely within the carrier (21). The opening of the flexible carrier (21) is covered with a mesh (31). The flexible carrier/magnet/mesh combination (20) is formed into the prosthesis (40) so that the prosthesis (40) aligns with the surgical steel implants (10) and allows freedom of movement within the flexible carrier (21). The mesh material (31) allows for breathability and also avoids skin strangulation from excess pressure of the magnet (30) on the surgical steel implant (10).

L'invention concerne une prothèse externe (40) et un procédé de pose de prothèse sur une personne, au moyen d'aimants (30), logés de façon adaptable, et interagissant avec des implants en acier chirurgical (10) insérés sous la peau de la personne. Les implants sont des boutons en acier chirurgical, recouverts de méthacrylate de méthyle pour éviter la libération de produits de corrosion, et de Silastic, un matériau biocompatible. On insère l'implant (10) sous la peau du patient, avec un matériau du type filet biocompatible (15), pour fournir une résistance supplémentaire. On forme un support souple (21) de forme cylindrique et creuse, pour permettre à un aimant (30) de se déplacer librement à l'intérieur dudit support (21). L'ouverture du support flexible (21) est recouverte d'un filet (31). On installe l'ensemble support/aimant/filet (20) dans la prothèse (40) de façon que les aimants de la prothèse (40) s'alignent avec les implants en acier chirurgical (10) et puissent se déplacer librement à l'intérieur du support souple (21). Le matériau de filet (31) permet à la fois de laisser respirer la peau, et de lui éviter de subir une compression excessive résultant de la pression de l'aimant (30) sur l'implant en acier chirurgical (10).
