Definitions

  • the invention is especially related to a magnetic apparatus which is used to remove the wire retainers.
  • These wire retainers fasten the Kirschner wire that is used for compressing and fixing the fractured fragments by being past through the fracture line. After bone healing gained by these, wire retainers, these wire retainers are taken out of the skin with the help of this magnetic apparatus.
  • Kirschner wire k-wire
  • screw k-wire
  • plate screw k-wire
  • intramedularry nail k-wire
  • intramedularry nail k-wire
  • external fixation The purpose of these techniques is to fix the fractured fragments in the desired position until healing.
  • the advantages and disadvantages of these techniques change according to the type of fracture and shape the treatment plan of the surgeon.
  • the fragments are first placed into their original places. Compression between the fragments is obtained according to the principle of forming mutual force between the screw head, and the screw threads which is the working principle of screw. In this technique it is required to increase the dimensions of the screw to increase the compression force and the adherence. However, if the sizes of the fragments are small, the dimension of the screw can not be increased. Due to the screw size, no space may be left to locate an additional screw between the fragments. Additionally, as a surgical technique, first the bone is drilled with a drill and then, thread holes are opened for screw thread and afterwards, the screw is placed. Additionally, before these processes, sometimes k-wire is needed to be placed to guide the screw. As a result, the surgical technique is relatively complex. Moreover, the compression provided by screw threads may not be enough for patients with osteoporosis.
  • the main objective of the invention is to present an embodiment comprising magnet in order to take the "wire retainers" - which is a subject to the patent with examination - out of the skin after bone healing with little damage to the soft tissues.
  • the object of the invention is to take the wire retainers out with percutaneous techniques during the removal of implants by minimizing the damage given to the bones and the surrounding soft tissue.
  • Figure 1 is the general view of the magnetic apparatus subject to the invention.
  • Figure 2 is the view of the magnetic apparatus subject to the invention in usage with cannula. DESCRIPTION OF THE REFERENCES R. Retainer
  • the invention is used together with "A wire retainer" which is subject to the patent application number 2010/05662 from Turkish Patent Institute and used in the fixation of the broken bones.
  • Said magnetic apparatus especially provides the removal of the wire retainers subject to the patent application number 2010/05662, with percutaneous techniques.
  • Magnetic apparatus subject to the invention in general comprises;
  • a magnet (2) located at the end part (1 ) of the body (3) and shaped in accordance with the dimensions of wire retainer (R), for gripping the wire retainer (R) and preventing its disconnection from the apparatus while removing it from its location;
  • This magnetic apparatus developed for wire retainer (R) provides the removal of said retainer (R) after the completion of the healing of fracture.
  • it provides access to the wire retainer (R) through the working cannula (6) with percutaneous . technique.
  • Manual guiding is possible by means of holding part (4).
  • the end part (1 ) of the invention may comprise magnet grooves having different shapes, varieties and dimensions in accordance with the dimension and shape of the wire retainer (R).
  • the magnet may have different diameters, shapes, dimensions and varieties.
  • the shape of the body (3) subject to the invention may have a different shape (other than cylinder, such as hexagonal, rectangle) and length.
  • the holding part (4) of the invention may be "T", "L", "C” shaped or may have another shape.
  • the magnetism of the invention may be provided by electrical systems.
