Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A device for localizing and executing resection cuts on the femur (1) for preparing an implantation of a total endoprosthetic knee joint is provided. The device includes a reference device (5) adapted to be releasably attachable to the femur (1) in the distal area of the femur (1). Alignment of the reference device (5) relative to the femur (1) should be accurately positionable. An adjustment device (10) is connected to the reference device (5). The adjustment device (10) is movable relative to the reference device (5) and is provided with a linearly movable base part (10g) for the attachment of an instrument (11, 14). A first drive device (5v, 21) linearly moves the adjustment device (10) relative to the reference device (5) in the direction (10b) of a first axis (X) of a system of coordinates (X, Y, Z). A second drive device (10f, 17) linearly moves the base part (10g) in the direction (10d) of another, second axis (Y) of said system of coordinates (X, Y, Z).

Abstract: A pump having electronic and mechanical components which allow an individually adjustable operation. Certain components periodically transform a driving current for an electrical drive. An adjustable clock generator adjusts transformation frequency. Pumping volume is determined and limited as desired by means of a position detection device. The pump also includes components for measuring the driving current that interact with an adjustable current-limiting device, thus allowing the pumping pressure of the pump to be adjusted and limited. The pump may include several pump cylinders which are controlled by a position control circuit in such a way that the generated partial vacuum follows a predetermined time characteristic.
