The inclined surfaces of the first and second clamping elements are in contact. A screw extends at least partly through both the first and second clamping elements. The screw engages in one of the clamping elements such that the axial distance between the two clamping elements and the diameter of the clamping section that can come in contact with a surface of the opening in the medical device will be changed upon actuation of the screw. | 08-06-2009 |
20090198292 | Wire fixation device - A wire fixation device for fixing a tensioned wire or a pin to a medical device has a wire post having a head portion with an opening having a predetermined longitudinal axis for reception of a wire or pin. The wire post has a neck portion for being in engagement with an opening of the medical device. A locking element is adapted to be introduced into opening having an opening with inclined sections that are inclined to the longitudinal axis. A clamping cone abuts on an abutment element. The clamping cone has a clamping opening to accommodate a wire and has inclined outer surfaces that are inclined to the longitudinal axis and which are encompassed with the conical section of the locking element. Upon an axial displacement of the locking element relative to the clamping cone a radial force is exerted onto the clamping cone leading to a reduction of the diameter of the clamping opening such that if a wire or a pin is received in the clamping opening a radial force results onto the wire or the pin. | 08-06-2009 |
20090264882 | External fixation system - An orthopedic fixation ring for an external fixator has a ring or a ring-segment extending around a center axis. The ring comprises a first surface running perpendicular to the center axis, a second surface which is parallel to the first surface, and a plurality of spaced apart through openings running parallel to the center axis and extending through the fixation plate. The fixation plate has at least a third surface which is parallel to the first surface spaced outwardly thereof with respect to the center axis. A further set of through openings extends from the first surface to the third surface. A fourth surface may be provided which is axially displaced from the second surface with respect to the center axis. The ring preferably is circular or part-circular and is molded from carbon fiber reinforced PEEK. | 10-22-2009 |

20090148232 | External fixation clamp - An insert for an external fixation has two jaws for clamping a rod-shaped element. The insert includes a locking element and is an angled piece having two free ends, with at least one engagement edge for engagement into the rod-shaped element being provided at its one free end. The insert has a recess or bore for engagement with a locking shaft of the clamp provided at the free end thereof that lies opposite to the free end having the rod engagement edge. The insert is angled so that it may extend through a passageway in one of the jaws and into a cavity formed in the jaw for receiving the rod. The insert rod engaging edges are tapered to bite into the rod to prevent its movement. | 06-11-2009 |
20090264883 | Radiolucent orthopedic fixation plate - An orthopedic fixation plate comprises a plurality of cylindrical holes for attaching connectors of a external fixation system, wherein the fixation plate comprises two supporting elements around each orifice of a cylindrical hole wherein the supporting elements are connected with a sleeve and said supporting elements are also connected with a longitudinally oriented ring element arranged in a radial distance of said sleeve. | 10-22-2009 |
20110288549 | EXTERNAL FIXATION SYSTEM - An orthopedic fixation ring for an external fixator has a ring or a ring-segment extending around a center axis. The ring comprises a first surface running perpendicular to the center axis, a second surface which is parallel to the first surface, and a plurality of spaced apart through openings running parallel to the center axis and extending through the fixation plate. The fixation plate has at least a third surface which is parallel to the first surface spaced outwardly thereof with respect to the center axis. A further set of through openings extends from the first surface to the third surface. A fourth surface may be provided which is axially displaced from the second surface with respect to the center axis.
