  • Publication number: 20210030442
    Abstract: A bone plate for reconstruction or trauma treatment of a bone which comprises first and second ends, a first contact surface for contacting and securing on a first region of the bone, and a plurality of receiving mechanism each having at least one opening for receiving at least one securing element. At least two adjacent wings extend at least from the first end of the main section, each has a second contact surface for contacting and securing to a second region of the bone, as well as at least one receiving mechanism having at least one opening for each receiving a securing element. A minimum bending stiffness of the main section, in relation to an axis (x) running perpendicular to the first contact surface, is greater than the minimum bending stiffnesses of the wings, but smaller than the total minimum bending stiffness of all wings extending from the first end.

  • Patent number: 10751100
    Abstract: A bone screw comprising a first end having an engagement contour for engaging with a tool to facilitate insertion or removal of the bone screw, and a blocking element is arranged at a second end thereof. The blocking element is provided with a circumferential outside surface which comprises at least one clamping surface which—when viewed in an azimuth plane perpendicular to a longitudinal axis of the bone screw—widens outwardly in a wedge-shaped manner away from the longitudinal axis. The bone plate includes at least one opening which is at least partially delimited by an inside wall having an inner contour for receiving and fixing the blocking element of the bone screw. At least one bone screw and at least one bone plate together form a surgical set.

  • Patent number: 9554837
    Abstract: A fixation device is used to fix an elongate element, in particular a wire, in an opening of a retaining structure, in particular of an implant plate. The fixation device has a main body. The main body is provided with a bore for receiving the elongate element. The main body is radially deformable in a clamp area, such that the diameter of the bore can be reduced. The main body has an outer contour which is designed in such a way that, when the fixation device is inserted into the opening of the retaining structure, the clamp area is deformed such that the elongate element is clamped securely in the bore.

  • 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.

  • Publication number: 20050090825
    Abstract: A bone plate is provided for treating a fracture, especially a fracture of an atrophic mandible, which bone plate comprises a plurality of eyelets through the holes of which screws can be screwed into the bone fragments in order to fasten the bone plate to the bone fragments so that the bone fragments on one side and on the other side of the fracture are maintained in a desired position relative to one another by means of the bone plate. The bone plate has a plate thickness in the range of from 0.5 mm to 1.

  • 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.

  • Patent number: 5822865
    Abstract: A cutting pliers for cutting implant plates features two handgrips (10) joined via a hand-grip pivot (11), which handgrips actuate by way of leverage pivots (14) a pliers holding jaw (15) and a pliers punching jaw (16). Formed on the pliers holding jaw (15) are holding pins (19, 20, 21) adapted for entering matching recesses of the implant plates being cut. A cutting device (18) is fashioned on the pliers punching jaw (16). Implant plates of different implant systems, with half-round, burrless cuts, can be cut with said cutting pliers.

  • Patent number: 5605080
    Abstract: The present invention involves screwdriver having a grip, a driver blade insertable into and rotationally affixed to said grip and a chuck. The chuck encloses and is longitudinally displaceable relative to the driver blade. The chuck has collets extending from an end disposed near the blade tip. The collets have claws extending from their free ends which are adapted to retain a screw on the blade tip when the chuck is in a retaining position. The collets may be either inwardly biased or outwardly biased. A sleeve, for pressing the collets inward, is provided for embodiments employing outwardly biased collets. A stop device is provided for inhibiting the longitudinal displacement of the chuck towards the blade tip beyond the retaining position. The stop device comprises a groove in the blade shaft and a cooperating detent spring located on the chuck. The free end of the detent spring extends toward the blade tip and is biased inward so that it is disposed within the groove.
