  • Shackle element for clamping a fixation rod, a method for making a shackle element, a hook with a shackle element and a rode connector with a shackle element
    Patent number: 6749361
    Abstract: A shackle element, a method of making a shackle element, a hook and a rod connector. The shackle element (18) is used for fastening a hook (12), or respectively a rod connector, on a fixation rod (10). The shackle element (18) forms a groove with a lateral opening for inserting the fixation rod (10). The groove is delimited by a groove bottom (18.1) and two lateral walls (18.2, 18.3). After mounting the groove bottom (18.1) encloses the fixation rod (10) over an angle of 180° plus a partial angle. The lateral walls are arranged under a small angle; their distance increases with growing distance from the groove bottom so that the lateral opening is large enough for introducing the rod. The lateral walls are intended to be pushed together by means of a screw device (20.1, 20.2) for clamping the fixation rod (10). The groove bottom (18.1) encloses the fixation rod (10) over an angle of 180° plus a partial angle.

  • Clamping arrangements for an orthopedic fixation device and use thereof
    Patent number: 5984928
    Abstract: The clamping arrangement (1, 6) comprises a clamping body (6) and an implant pin (1) fastened therein. The clamping body (6) has a recess (7) for receiving the implant pin (1) and a slit (10), starting at the recess (7), by means of which two clamping jaws (8, 9) are formed which, when pressed together, cause the fastening of the implant pin (1). The slit (10) is arranged in such a way that its imagined extension contains the longitudinal axis of the implant pin (1). To reduce material fatigue and wear, either the outer surface of the implant pin (1) or the wall of the recess (7) have set-back areas (6.7, 6.8), which do not touch the surface respectively located opposite them. With suitable embodiment and arrangement, the set-back areas and the relief recesses (1.3, 1.4, 6.3, 6.4) can be created in the same step, in particular by means of a screw thread or several channels in the implant pin (1) or the recess (7).
