  • Patent number: 9993333
    Abstract: A system (100) for a controlled stressing of a reconstructed or re-natured ligament of a human or animal body comprises an anchoring element (10) for implantation in a first bone (50), at least one connecting element (120) and a holding element (30), which fixes the at least one connecting element (20) in a second bone. According to the invention, an elastomer element (125) is arranged in the anchoring element and/or in the connecting element (120) and provides a defined elastic action through the cooperation of elastomer element (125) with the connecting element (120).

  • Patent number: 9032618
    Abstract: A method for insulating (5) a conductive bar (1) includes wrapping an insulating tape (2) around the conductive bar (1), enclosing it in a flexible container (4), applying a vacuum, impregnating the insulating tape (2) with an impregnating resin, curing the impregnating resin, and removing the conductive bar (1) with the insulation (5) around it from the flexible container (4). In addition, together with the insulating tape (2), an impregnating tape (3) made of the impregnating resin is wrapped around the conductive bar (1). In order to impregnate, the impregnating tape (3) is melted.

  • Patent number: 7618417
    Abstract: A clamping element for the clamping of multiple rod-shaped elements has two opposing jaws, which have a number of corresponding grooves for the acceptance of a corresponding number of rod-shaped elements such as bone pins. Spring elements are provided, with which in the resting position the closed jaws are tensed, to hold the rod-shaped elements in position.

  • Patent number: 7241074
    Abstract: A one-piece clamping element has two opposing clamping jaws forming a laterally open cavity to receive a rod-shaped element. A hinge is located between the jaws, arranged opposite the cavity, and connecting the clamping jaws with one another and thus allowing them to be movable with respect to one another. Each clamping jaw has one bore, aligned flush with one another. One clamping jaw has a receptacle for an anti-rotation device. The receptacle makes it preferable—with the exception of an immediate tightening of the screw in this or another place of an external fixator clamping element used for the same patient—to use the clamping element only once and discarding it after use. Two identical clamping elements, with the possible exception of the size of the rod receptacle, can be placed on top of one another to form an articulation element.

  • Patent number: 6808526
    Abstract: An osteosynthesis screw (1) used especially for application by a translaminar vertebral screw, comprises a shaft (3) at least partially provided with a thread (2) and a head (4) formed at one of its ends and having a notch (5) for a tool. Said shaft (3) has a section (A) with a thread (2) on the end section oriented towards the head (4). The remaining section (B) of the shaft (3) up to the free end is produced without a thread. The head (4) has a diameter (D1) corresponding at least approximately to the outer diameter (DA) of the thread (2) and is provided with the inner notch (5) for a tool. The section (A) of the shaft (3) with the thread (2) has a configuration of uniform thickness, e.g. a trilobular configuration. Thus, the invention provides an osteosynthesis screw (1) exhibiting a short section (A) with a thread (2) and a long section (B) without a thread, said screw having a pull-out head (4) which is secured both axially and rotationally.

  • Patent number: 6786909
    Abstract: An implant for osteosyntheses including a plate with a plurality of holes following in succession in the longitudinal direction whereby at least most of the holes intended to receive the screws are offset in alternation generally away from a center plane whereby a center axis of each of the holes forms an acute angle with the center plane of the plate.
