    摘要: An osteosynthetic fixation device consists of a fixation element 1 which has a conical head section 11 and an anchoring element 12 abutting it which is for attachment into the bone. The fixation device also consists of a spherically formed, layered, slotted clamping piece 2 which has a conical borehole 21 for installation of the conical head section 11, and which is meant for locking within a connecting piece 3 equipped with a spherically shaped layered borehole 31. Fixation piece 1 has an axially arrayed tension element 4, permitting axial displacement and wedging of conical head section 11 in the borehole 21 that corresponds with it. The fixation device is appropriate for use as a plate/screw system, an internal or external fixator, and in particular for spinal column fixation.

    摘要: The connection device (20) for adjustable connection of a first with a second structural element (12, 13), particularly tubes or rods, for a setting device has an external component (21) with a cylindrical hole and two internal components (22) inserted into the hole so that they can be slid axially and rotatably, each of which said internal components (22) has through openings (24, 25) crossways to the axial direction of the components to hold a structural element (12, 13). By means of loading means (23, 29), designed as a nut/screw connection, the internal component (2) is pushed axially to the external component (21) and thereby grips the inserted structural elements (12, 13). A recess (26) in the internal component (22) effectuates a flexible radial deformation of the internal against the external component (22, 21), said deformation being created through the inserted structural element (12, 13), and an additional bonding of the connection device (20) is thereby achieved, which considerably improves the setting.
