INSERT FOR USE IN A WEAR COUPLE INCLUDING A SPHERICAL WEAR PARTNER
Publication/Patent Number: US2021282934A1 Publication Date: 2021-09-16 Application Number: 17/053,281 Filing Date: 2019-05-06 Inventor: Juszczyk, Mateusz Maria   Assignee: CeramTec GmbH   IPC: A61F2/30 Abstract: The invention describes an implant for wear couples in endoprosthetics, comprising at least one shell, into which an insert, preferably a ceramic insert, is introduced. The insert has an outer side, with an outer face, and an inner side, and a hemispherical wear region for accommodating a spherical wear partner being formed on the inner side. The aim of the invention is to reduce the height of the implant as much as possible and to ensure that, e.g., the pelvic bone does not have to be milled down as much. According to the invention, the insert is therefore designed in the form of a ring or annular structure. In order to reduce friction between the spherical wear partner and the implant to a minimum, the implant has a specially designed inner geometry.
