METHOD OF TESTING CERAMIC COTYLOID CAVITIES FOR HIP JOINT ENDOPROSTHESES |
摘要 |
<p>A ceramic socket or ceramic socket insert for a hip joint prosthesis is tested prior to implantation in a human body by subjecting the portions of the interior of the socket or socket insert to a load that generates stresses that are greater than the physiological load. This may be accomplished either by pressing a hemispherically-shaped deformable material such as polymer or plastic into the interior of the socket or socket insert or by exposing the interior of the socket or socket insert to a fluid under pressure. The interior of the socket or socket insert may be sealed off with a test punch that has a supply line for the fluid. To reduce the amount of fluid that is required, the test punch may have a bulge that projects into the interior of the socket or socket insert and leaves only a gap for the fluid. In the method of testing, the interior of the socket or socket insert is subjected to a load that generates stress such that a defective socket or socket insert is destroyed and a non-defective socket or socket insert survives unharmed.</p> |
