  • Publication number: 20140046387
    Abstract: Disclosed is a clamping element for setting a bone fracture. The element comprises a flexible and substantially non-plastically deformable continuous loop inside which at least two fixing elements can be pushed through, and an extension element of alterable length that can be inserted into and is expandable inside the continuous loop in such a manner that in order to enable the extension element to apply forces to the fixing elements, said forces being directed towards each other, a predetermined tensile stress can be generated over the circumference of the continuous loop. Also disclosed is a setting device comprising the clamping element.

  • Patent number: 8597300
    Abstract: A bone fracture fixation system comprises a bone plate configured to bear against a proximal surface of the bone and a plurality of elongated tension elements, each sized to pass through an opening in the bone plate and through the bone from the proximal surface to a distal surface thereof. Each tension element is anchored to the bone and maintained in tension by a distal anchor attached to said tension element and configured to engage the distal surface of the bone and a proximal anchor engageable between the bone plate and the tension element. In one method for fixation of a bone fracture, the bone plate is positioned on a proximal surface of the bone while the tension element is introduced into the bone and through an opening in the bone plate from an opposite distal surface of the bone.

  • Publication number: 20130310884
    Abstract: A surgical assembly has a first section having a first hole with a smallest diameter and a second section having a threaded second hole with a minor thread diameter smaller than the smallest diameter of the first hole. The first hole encloses a center axis of the second hole and a clearance is provided between the first section and the second section. The assembly includes a screw member having a length for engaging the first hole and the second hole so as to bridge the clearance. The screw member has a first portion with a largest outer diameter smaller than or equal to the smallest diameter of the first hole, and a threaded second portion axially spaced from the first portion and configured to threadedly engage the second hole. A major thread diameter of the second portion is larger than the smallest diameter of the first hole.

  • Publication number: 20130310885
    Abstract: The present invention discloses a securing device that is used to secure a fixation device to two bone portions to promote healing between the two bone portions. The bone portions commonly include a skull bone portion and a skull bone flap or implant, and the fixation device is commonly a cranial clamp. The securing device provides for securing the fixation device in a uniform, single movement as opposed to currently available products. The securing device has two handles pivotably connected, and a gripping means moveably associated with one handle. As the handles are activated, the gripping means travels proximally along the one handle and grips an elongated section of the fixation device and exerts a tensioning force along the shaft of the elongated section prior to the cutting means cutting the elongated shaft to secure the fixation device in place.

  • Patent number: 8579950
    Abstract: A pair of clamps are attached to a damaged bone one each side of a fracture site during a surgical reduction, one clamp on each side of the fracture site, after which the two clamps are slidably engaged to a single alignment bar, with the clamps then being adjusted to properly align the bone for a surgical attachment using a bone plate. Each clamp provides axially adjustable plate retainers which slides along a track on the end of each segment of the each clamp to position the retainers at a location where the bone plate is to be attached to the bone. Upon positioning, the bone plate is held against the bone with the bone still in proper alignment wherein screws anchor the plate to the bone, stabilizing the fracture site during the plate attachment procedure.

  • Patent number: 8540713
    Abstract: A clamp applicable to both temporary and definitive orthopaedic external fixation systems comprising a first coupling element having a pair of opposite jaws defining one or more seats to house a first component of the orthopaedic external fixation system. A second coupling element comprises a pair of opposite jaws defining one or more seats to house a second component of the orthopaedic external fixation system. An interconnection pin passes through and connects the first and second coupling elements along an axis of rotation. A fastening means is arranged to bring the clamp from a slack configuration. The first and second coupling elements are relatively rotatable along the axis of rotation to a locked configuration, and are relatively rotatable with each other. These fastening means include manually operable temporary fastening means to temporarily lock the clamp, and definitive fastening means operable with a fastening tool, to definitively lock the clamp.

The receiving portions of one clamp assembly may receive at least two fixation components such as screws, pins or wires. The receiving portions of the other clamp assembly may receive at least one connector such as a rod, bar and/or ring. A biasing structure may be positioned between the first and second clamp assemblies and may allow for the fixation components to be snapped into the receiving portions through the insertion portions. Two or more adjustable fixation clamps may be used to form an external fixation system. At least two screws, pins or wires may be inserted into bone and one of the clamp assemblies may be attached thereto. A guide may be used for insertion of screws, pins or wires into bone.
