  • Patent number: 9155577
    Abstract: A locking element and a corresponding housing are disclosed, for the locking of the locking element in housing. The locking element includes a locking piece, for example a head, with a peripheral outer surface, running essentially in the direction of a longitudinal axis with at least one clamping surface extending outwards from the longitudinal axis in the form of a wedge, in order to lock the locking piece on the locking element with a corresponding inner contour of the housing. The peripheral outer surface is at least approximately spherical, parabolic, elliptical or hyperbolic in embodiment, viewed in the direction of the longitudinal axis in the region of the clamping surface, which is also true for the inner contour of the housing in the region of the recess, whereby the recess cooperating with the clamping surface can also be cylindrical.

  • Patent number: 8366751
    Abstract: A bone plate has at least one plate hole whose hole axis runs obliquely in relation to the underside of the plate. The hole axis has an elevation angle (?) in relation to the plane of the underside of the plate which is different from 90°, and in which plate the upper face of the plate runs at least partially not parallel to the underside of the plate, at least in the area around the plate hole, but instead runs at a right angle to the hole axis. The plate hole is designed such that a bone screw, which is screwed into the plate hole, can be blocked in the plate hole at an angle selected from a predefined angle range around the elevation angle (?) of the hole axis of the plate hole only by cooperation of the plate hole with the bone screw, without other additional auxiliary means.

  • Patent number: 6730091
    Abstract: The blockable bone plate consists of a plurality of plate members which are connected to each other via webs. A screw hole is provided in at least some plate members, preferably in each plate member. The screw hole is surrounded by a spherical countersink on the upper surface of the plate. Provided internally in the screw hole there is an engagement contour which consists of contour valleys and contour peaks partially running in a horizontal and radial peripheral direction on the wall of the screw hole. The engagement contour is preferably produced by milling and has for example a pointed, round, trapezoidal or serrated configuration. A blocking thread is provided under the screw head of the screw intended for blocking. As the screw is screwed in, the blocking thread engages in the engagement contour. The particular advantages lie in increased security against the screw coming loose and in the possibility of also inserting the screw through the plate at an inclination.
