Patent ID: 10568748

Abstract:
The invention relates to a connection device for connecting a first and a second prosthesis part, in particular of a tibial and a femoral trial prosthesis for trial arrangement on the corresponding bones, wherein the connection device has a first connection element and a second connection element. The first connection element has inner walls, serving as a guide, and a mating piece and serves for arrangement on the first prosthesis part, and the second connection element is enclosed at least in part by the inner walls of the connection element and is movable in a displacement direction along the inner walls relative to the first connection element and has a groove for receiving a portion of the second prosthesis part. The second connection element is movable, in the direction of displacement relative to the first connection element, to an open position in which the second connection element is at least in part pushed out of the first connection element and the groove of the second connection element is at least in part exposed such that the portion of the second prosthesis part can be inserted into and guided out of the groove, and to a closed position in which the second connection element is at least in part pushed into the first connection element and the mating piece of the first connection element lies opposite the groove of the second connection element, in such a way that the portion of the second prosthesis part received in the groove is prevented, by the mating piece of the first connection element, from withdrawal from the groove.
