TESTING APPARATUS FOR AN ORTHOPAEDIC SPECIMEN SUCH AS A KNEE IMPLANT PROSTHESIS

摘要

A testing apparatus is provided for exposing an associated specimen to movement along multiple axes. A test chamber is dimensioned to receive the associated specimen. A first device is operatively connected to the test chamber to impose a first, rotational movement on the associated specimen, a second device is operatively connected to the test chamber to impose a second, rotational movement different than the first movement on the associated specimen, a third device is operatively connected to the test chamber to impose a generally planar movement or linear translation on the associated specimen, and a fourth device is operatively connected to the test chamber to impose a load force on the associated specimen. A drive mechanism is operatively connected to the first, second, third, and fourth devices so that the movements and forces imposed by respective ones of the devices are commonly driven by the drive mechanism.
