A bone clamp for securing of a measurement aid to a bone comprises a first clip and a second clip and an adapter. The adapter comprises a pulling mechanism and a locking mechanism, whereby the position of the first clip relative to the second clip can be altered by actuation of the pulling mechanism, wherein the position of the first clip relative to the second clip can be fixed by actuation of the locking mechanism. The first clip and the second clip each have an inner face which is oriented in the direction of the bone, wherein the first clip has one or more spikes on the inner face and wherein the second clip has a sliding edge on the inner face.

A ligament-tensioning device and method for activation of the ligament and/or capsule system in the implantation of a joint implant. The device includes a distal bearing plate for bearing against a distal skeletal part, and also includes first and second proximal bearing plates, each of which partially overlaps the distal bearing plate in a first in-use position, for bearing against a proximal skeletal part. The device further includes means for relative displacement of the proximal bearing plates to increase their spacing from the distal bearing plate. The displacement means includes a scissor-type guide means that supports the respective proximal bearing plate in the ventral-dorsal as well as the medial-lateral parallel position with respect to the distal bearing plate.

A pre-load unit, for inserting a lens into the eye of a human or animal, includes a housing, a lens-receiving part arranged on or in the housing, having a section that protrudes from the housing, and two separate leaf-like units which, at least at their ends directed away from the housing, are in releasable contact with each other and form a chamber of storing an optical lens. A slide which is arranged movably in the interior of the housing can be moved between the leaf-like units of the lens-receiving unit. The pre-load unit may be combined with a grip piece, wherein the pre-load unit and the grip piece are connected to each other in such a way that the pre-load unit can be moved inside the grip piece.

A marker for a navigation system for determining the spatial position (e.g., of a surgical instrument), said marker including a retroreflective ball (). A retroreflective surface () of the ball () is protected by a dimensionally stable, translucent or transparent shell () in such a way that the reflected image remains essentially uninfluenced in terms of contour and the position of the centre of gravity.

A method of finding the position of a mechanical axis running in the longitudinal direction through a limb that is rotatably supported by its first end in a center of rotation that is not fixed and is not accessible for the mechanical determination of coordinates, by means of an optical coordinate-measurement device with an indicator to detect measurement-point coordinates in one rotational position of the limb such that, for each rotational position, a multi-point indicator rigidly attached near the second end of the limb signals several measurement-point coordinates, and, from the sets of measurement-point coordinates detected in a plurality of rotational positions, at least one group is selected that can be assigned to the same site of the center of rotation, and the measurement-point-coordinate sets assigned to this site of the center of rotation are used to calculate the mechanical axis.

A knee-joint prosthesis with a tibial part having a flat tibial bearing surface, with a bearing body that can be shifted thereon in the anterior-posterior direction and includes two concave bearing shells within which a femoral joint part can be movably seated, and with a rotational guide that permits rotation of the bearing body on the tibial bearing surface about an axis of rotation perpendicular to said surface. The rotation guide includes a steering rod that is seated at the bearing body so as to be pivotable relative thereto and at the tibial part is guided in the medial/lateral direction and/or rotationally guided.

Knee-joint endoprosthesis

A device for localizing and executing resection cuts on the femur ( ) for preparing an implantation of a total endoprosthetic knee joint is provided. The device includes a reference device ( ) adapted to be releasably attachable to the femur ( ) in the distal area of the femur ( ). Alignment of the reference device ( ) relative to the femur ( ) should be accurately positionable. An adjustment device ( ) is connected to the reference device ( ). The adjustment device ( ) is movable relative to the reference device ( ) and is provided with a linearly movable base part ( ) for the attachment of an instrument ( ). A first drive device ( ) linearly moves the adjustment device ( ) relative to the reference device ( ) in the direction ( ) of a first axis (X) of a system of coordinates (X, Y, Z). A second drive device ( ) linearly moves the base part ( ) in the direction ( ) of another, second axis (Y) of said system of coordinates (X, Y, Z). Both the first and second drive devices ( ) include a motor drive.
