  • Patent number: 8298241
    Abstract: The invention relates to a universal extractor for total endoprostheses (TEP) of the knee joint. The object of the invention, namely to make available a universal extractor for artificial knee joints that avoids the disadvantages of the prior art, is achieved by the fact that the universal extractor comprises the following parts: a T-piece with an extraction plate and with a securing arm, the securing arm being fork-shaped and slotted at its distal end and supporting the extraction plate at its proximal end; a scissor mechanism with clamping jaws located at its free distal ends, said securing arm holding the scissor mechanism by means of a securing pin about which the scissor mechanism can move; and an eyebolt which is mounted on the proximal end of the scissor mechanism and has a knurled nut, the eyebolt being adjustable and connecting the ends of the scissor mechanism to each other, so as to permit fixing or release of the clamping jaws which have a shovel-shaped, U- to V-shaped geometry.
