Patent number: 11771478Abstract: An instrument for locking and unlocking a head of a bone anchor relative to a receiving part of a polyaxial bone anchoring device includes a tube assembly with an inner tube and an outer tube at least partially around the inner tube, and an actuator assembly including an actuating mechanism movable from a first orientation to a second orientation to displace the inner tube and the outer tube relative to one another between a first axial position configured to unlock the bone anchoring device such that the head is pivotable relative to the receiving part, and a second axial position configured to lock the head. The actuator assembly is adjustable between a first configuration where the tube assembly assumes the first axial position when the actuating mechanism is moved, and a second configuration where the tube assembly assumes the second axial position when the actuating mechanism is moved.Type: GrantFiled: June 25, 2021Date of Patent: October 3, 2023Assignee: BIEDERMANN TECHNOLOGIES GMBH & CO.

Patent number: 11134991Abstract: A stabilization device for bones or vertebrae includes a rod having a rod axis and a plurality of distinct external surfaces that extend parallel to the rod axis, such that for a cross-section of the rod, the distinct external surfaces are arranged at respective angles relative to one another around the rod axis, a bone anchoring device including a receiving part having a channel for receiving the rod and a contact surface for supporting the rod, and a fixation member with a contact surface for fixing the rod in the channel. When the rod is fixed in the channel with the fixation member, the contact surfaces of the receiving part and the fixation member together form surface portions that are shaped to correspond to at least three of the distinct external surfaces, such that the rod is clamped along the at least three distinct external surfaces.Type: GrantFiled: July 31, 2018Date of Patent: October 5, 2021Assignee: BIEDERMANN TECHNOLOGIES GMBH & CO.
