Abstract
The invention relates to a method and a device for manufacturing an articular prosthesis implant using a mould comprising a ceramic imprint (1) moved by a piston (2), the ceramic imprint (1) pressing the thermoplastic material introduced into the mould.
Claims9
Device for manufacturing an articular prosthesis implant (3) comprising the following steps:
- heating to a malleability temperature a thermoplastic material used to form at least partially the implant (3);
- inside a mould cavity and using a ceramic imprint (1) of the mould moved by a piston (2), pressing the thermoplastic material so that this material flows inside the mould cavity and takes the shape of the imprint (1);
- allowing the thermoplastic material to cool down;
- extracting the implant (3) obtained from the mould.
Manufacturing method according to the preceding claim, wherein the thermoplastic material is selected from ultra-high-molecular-weight polyethylene (UHMWPE) or polyetheretherketone (PEEK) or polyetherketoneketone (PEKK) and their derivatives.
Manufacturing method according to any one of the preceding claims, wherein a metal base (5), against which the thermoplastic material is pressed, is introduced into the mould cavity.
Manufacturing method according to any one of the preceding claims, wherein the ceramic is selected from alumina, composite, zirconia or oxynium.
Device for manufacturing an articular prosthesis implant (3) comprising:
- at least a mould comprising a ceramic imprint (1);
- at least a piston (2) configured to move the ceramic imprint (1) between at least two predefined positions, so that in one of these positions, the ceramic imprint (1) presses a thermoplastic material previously introduced into the mould cavity and so that, in the other position, the ceramic imprint (1) is not in contact with said thermoplastic material.
Manufacturing device according to the preceding claim, wherein the piston (2) is made of ceramic.
Manufacturing device according to the preceding claim, wherein the piston (2) and the imprint (1) form a monobloc element.
