Definitions

  • the invention is especially related to a squeezing apparatus which locks the wire retainer on kirshner wire, after placing the kirschner wire and the wire retainer in desired position.
  • These wire retainers fasten the Kirschner wire that is sed for compressing and fixing the fractured fragments by being past through the fracture line .
  • Kirschner wire k-wire
  • screw plate screw
  • intramedularry nail intramedularry nail
  • 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.
  • the compression provided by screw threads may not be enough for patients with osteoporosis.
  • fixation of the broken bones with plate and screw after reducing, the broken fragments are fixed to their locations by plates held by screws.
  • the plates are held by screws, all of the disadvantages of screw technique are also experienced in here.
  • the process of placing plates requires the abrasion of more tissue surrounding the bone. This means more incision and more vascularization problem for the bone pieces.
  • the plate may prevent the healing of skin where the subcutaneous tissue is very thin and may be felt by hand. When the bone pieces are small or very close to the joints, it is impossible to place the plates. Additionally, when they are needed to be taken out, the surrounding tissue is damaged again.
  • the main objective of the invention is to present an apparatus in order to place the wire retainers subject to the patent with examination, into the body during surgery with little damage to the soft tissues.
  • the object of the invention is to achieve bone healing by giving minimum harm to the bones and the surrounding soft tissue by using the wire retainers with percutaneous techniques.
  • An object of the invention is to provide the fixation after reducing with the help of thin wires and providing compression at the fracture line and to make it possible to compress small fragments.
  • An object of the invention is to use the thin k-wires for both compression and support by the virtue of a wire retainer.
  • Another object of the invention is to eliminate the important problem of collapsing of small fragments in fractures which are close to the joints such as knees by placing multiple k-wires beneath the fractured fragments.
  • An object of the invention is to eliminate the problem of formation of new fractures due to these thick slots by the usage of k- wires which are much thinner than these slots.
  • Another object of the invention is to provide compression over the wire by using the wire with the wire retainer subject to application 2010/05662 in cases where the bone anatomy such as fractures around the elbow does not allow the usage of thick fixation tools.
  • Another object of the invention is to carry out the surgery without groove opening, drilling etc.

  • Figure 2 is the general view of the squeezing apparatus subject to the invention from a different angle.
  • Figure 3 is the detailed/close up view of the tip of the squeezing apparatus subject to the invention.
  • Figure 4 is the usage view of the squeezing apparatus subject to the invention with working cannula and the gripper.
  • Detail A shows the squeezing apparatus when it grips the wire and when it is positioned for squeezing.
  • the invention is used together with "A wire retainer" which is subject to the patent application number2010/05662 from Turkish Patent Institute and used for the fixation of the broken bones.
  • Said squeezing apparatus (S) especially provides the usage of the retainer (T) subject to the patent application 2010/05662, with percutaneous techniques.
  • the invention is related to a squeezing apparatus (S) which rotates screwed system of the retainer and locks the retainer (R) by squeezing retainer (R) by the virtue of:
  • Wire holder squeezing apparatus (S) is developed to lock the retainer (R) subject to the patent titled "A wire retainer", after it is located onto the desired location on the bone ( Figure 4).
  • the squeezing apparatus (S) allows the upper part of the retainer (R) to be rotated on the k-wire (5) thanks to the k-wire channel (2) therein.
  • the shaped end (1 ) is shaped in accordance with the shape of the upper part of the wire retainer (R) ( Figure 3).
  • the wire retainer (R) is immobilized on the k-wire by the squeezing apparatus (S) with during the locking maneuver, which is rotation of the upper part of the retainer (R).
  • Access to the desired location where the retainer (R) is provided with the body (3) by the percutaneous technique and the opportunity for manual guidance and rotation is provided with the holding part (4).
