Abstract: A method for correcting colors of a color reproduction of a digital microscope and a digital microscope are described. In a first step of a method according to the invention, a color image of a sample that is to be examined under the microscope is recorded. When the recording is performed, wavelength-dependent properties of a microscope illumination unit that illuminates the sample are determined in order to describe a state of the microscope illumination unit, in that settings selected at the microscope illumination unit are captured. A set of correction values is determined, which is associated with a state of the microscope illumination unit that is selected in accordance with the state of the microscope illumination unit determined when the recording is performed. In a further step, the colors of the recorded color image of the sample are corrected by applying the correction values of the previously determined set.

Abstract: The invention relates to a method for operating a microscope device having a first and a second zoom microscope, wherein a zoom adjustment of the second zoom microscope is carried out in dependence upon a zoom adjustment of the first zoom microscope.

Abstract: A wide range zoom system, for microscopes. The zoom system includes five lens groups, of which, starting at the object side, the second and fourth lens group are displaceable in the axial direction relative to the first, third and fifth lens group. A stop of variable opening diameter that is stationary relative to the first, third and fifth lens group is provided between the second and fourth lens group, wherein the maximum opening diameter of said stop is in middle zoom magnifications. As magnification increases, the object-side aperture increases non-linearly in relation to the magnification, such that in regions of low magnifications the object-side aperture increases more sharply than in regions of higher magnifications.

Abstract: An intramedullary implantation system includes a nail with a head having a first locking element. A targeting guide includes a tubular body and a bore with first and second open ends. A locking device includes a shaft with a distal end having a non-threaded second locking element such that the locking device has a first angular orientation relative to the tubular body in which the first and second locking elements are engaged to secure the nail to the targeting guide. The locking device has a second angular orientation relative to the tubular body in which the first locking element is disengaged from the second locking element.

Abstract: An intramedullary nail configured for use in a bone, the nail including at least one bore configured to receive a bone screw. The bore includes at least one member configured to engage the threads of the screw to prevent axial motion of the screw within the bore after application. The member may be integrally formed in the bore or may be a separate member added to the bore. The member may have a variety of cross sectional shapes, such as a rectangular shape, circular shape or a triangular shape.

Abstract: A hydrogel bone plate spacer is provided for placement between a bone plate and an underlying bone to form a fracture fixation construct at a bone fracture site. The spacer includes a hydrogel able to absorb fluid from the fracture site.

Abstract: A system for percutaneous fracture repair of a bone is provided. The system includes a plate having a first feature and a second feature. The first feature and the second feature are spaced apart from each other. The plate defines a longitudinal axis of the plate. The system also includes a first attachment component operably associated with the first feature. The first attachment component cooperates with the bone. The system also includes a second attachment component operably associated with the second feature. The second attachment component is percutaneously inserted into the second feature. The second attachment component is operably associated with the plate to provide a compressive force in the bone. The compressive force has a component of the force in the longitudinal axis. The second attachment component is adapted for cooperation with the bone.

Abstract: According to the present invention, a fracture repair system for engagement with a bone is provided. The system includes a plate. The plate has a body portion and an internal wall defining a plate hole through the body portion. The system also includes one or more bushings having a radially exterior surface and an opposite radially interior surface defining a passageway. The exterior surface of the bushings and the interior wall of the plate are configured to permit polyaxial rotation of the bushings within the plate hole. The system also includes an attachment component having a distal portion sized for clearance passage through the passageway and into the bone and an opposite proximate portion sized to press the bushings against the internal wall of the plate to form a friction lock between the bushings and the plate in a selected polyaxial position. The attachment component is positionable in an orientation extending divergently from the center of the plate.
