Title (EN) METHODS OF FORMING A POLYMERIC COMPONENT
(FR) PROCÉDÉS DE FORMATION D'UN COMPOSANT POLYMÈRE
Abstract:
(EN) A method of forming a plurality of polymeric components comprises the steps of: providing an array of preforms (10), each preform (10) comprising crosslinked polymeric material; providing non-crosslinked polymeric material (28) around at least a portion of each preform (10); fusing the array of preforms (10) to the non- crosslinked polymeric material (28) so as to form a plurality of hybrid components; removing a portion of each preform (10) so as to deposit a crosslinked surface layer on the non-crosslinked polymeric material (28); and fashioning the hybrid components into the plurality of polymeric components. The polymeric components may constitute the whole or a part of a prosthesis, such as an acetabular cup prosthesis for use in hip resurfacing.
(FR) La présente invention concerne un procédé de formation d'une pluralité de composants polymères, le procédé comprenant les étapes suivantes : l'obtention d'un ensemble de préformes (10), chaque préforme (10) comprenant un matériau polymère réticulé ; la disposition d'un matériau polymère non réticulé (28) autour d'au moins une partie de chaque préforme (10) ; la fusion de l'ensemble de préformes (10) au matériau polymère non réticulé (28) afin de former une pluralité de composants hybrides ; l'élimination d'une partie de chaque préforme (10) afin de déposer une couche superficielle réticulée sur le matériau polymère non réticulé (28) ; et le façonnage des composants hybrides afin d'obtenir la pluralité de composants polymères. Les composants polymères peuvent constituer la totalité ou une partie d'une prothèse, telle qu'une prothèse à cupule acétabulaire utilisable pour la reconstruction de la hanche.
