The invention relates to medicine, namely to oral and maxillofacial surgery, and can be used in reconstructive surgery and traumatology.

Reposition displaced zygomatic bone and the zygomatic arches after their fracture is a necessary condition to achieve the normal architecture of the lateral division cf the Known Elevator Karapetyan (B. A. Smirnov, I. S. Karapetyan, 1967. A. C. the USSR 275300, Bulletin "Discoveries and inventions", 22, 1970, S. 69), used for intraoral reposition the zygomatic bone and the zygomatic arches, consisting of a handle and shtykovidnoe part.

This Elevator has a number of disadvantages, such as: the inability to move the bone fragments at the time of reset in all directions. Does not reposition of bone fragments in comminuted fractures in the correct anatomical position, has a damaging effect on the surrounding tissue.

Known perforating, cutting, dissecting and scalping tools designed to remove abnormal tissue from the nasal cavity and paranasal sinuses. The tools are made from an alloy based on titanium nickelide brand T-20. The main advantage of the tools is sufficient plasticity of the working part, allowing impart necessary for operative intervention form at high cutting properties and wear resistance. The tools consist of a handle, a neck and a working part in the form of a sickle cutting part or loop-like knife (kN. Medical materials and implants with shape memory. - Publishing house of Tomsk University, Tomsk, 1998. - S. 401-404).

Closest to the claimed is a tool and.with. The USSR 736971, And 61 In the 17/24, 1980, B. I. 20, page 20 to reposition the zygomatic bone.

The tool includes a handle and a working part in the form of a rod and two teeth.

Disadvantages of tool:

- does not provide a reduction of 2 or more bone fragments;

- its use is causing significant trauma to the operated tissues;

- difficulty aseptic processing before the operation.

The objective of the invention is low-impact and safe reposition the zygomatic bones and arcs in the correct anatomical position, creation of conditions for obtaining a favorable functional and aesthetic outcomes.

This objective is achieved in that the device is made in the form of an instrument containing the handle and the working part. The working part is made of Nickel-titanium, having the effect of thermoplate. Consists of stable rod, bent at an angle of 20 degrees relative to the handle, and part of that change shape with two subulate teeth, diverging at an angle of 30 degrees and oriented towards a stable rod at an angle of 60 degrees. At the ends of the subulate teeth are through holes cdaetsya the presence of his signs, missing from the prototype:

1. The working part of the device is made of titanium nickelide with the effect of thermoplate and consists of a stable core and a part that can change shape.

2. Changing part of the device is made of two subulate teeth.

3. Stable rod bent at an angle of 20 degrees relative to the handle in accordance with the contours of the face in this area, making it convenient for insertion under the bone fragments.

4. Two subulate teeth, diverging at an angle of 30 degrees, taking in the wound V-shaped, providing a large area of contact with the bone, simultaneously capture two or more bone fragments.

5. The introduction of the tool is through the puncture in the skin or mucous membrane, as in this moment subulate teeth is reduced, and take the form of sewing.

6. The variable geometry form the working part and the orientation of its subulate teeth at an angle of 60 degrees relative to a stable core allows a force sufficient to offset the bone fragments in the correct anatomical position.

7. At the ends of the subulate teeth are through holes for applying ligatures.

Suscestvennoj and scientific literature, information about similar devices, have the same set of features.

The device illustrated by the drawings presented on

Fig.1:

a). General view of the tool side,

b). Front view;

Fig.2. General view of the instrument at the time of thermomechanical steps:

b). The front view.

The tool consists of a handle 1 and a working part. The working part is made of titanium nickelide with the effect of thermoplate and includes a stable part 2, made in the form of a rod, bent at an angle of 20 degrees relative to the handle, and the part that changes the form, in the form of two subulate teeth 3, diverging at an angle of 30 degrees and oriented towards a stable rod at an angle of 60 degrees. At the ends of the subulate teeth are through holes 4 for applying ligatures.

The device operates as follows. Before the reposition of bone fragments device is cooled solution of chloroethyl or liquid nitrogen. Two subulate teeth 3 are deformed, they are given subulate form that allows you to easily enter the tool through a single puncture, thereby to avoid excessive damage to the surrounding soft tissues. Then the device is inserted under the bone to reposition. In the process nagrywania at an angle of 30 degrees, take in the wound V-shaped, providing a large area of contact with the bone, simultaneously capture two or more bone fragments, working part takes the initial position for the reposition of bone fragments up to 1.5 cm, which allows you to set the bone fragments in the anatomical position. At the ends of the styloid processes are through holes that are intended for ligatures.

Thus, the tool to reposition the zygomatic bone and the zygomatic arches helps to achieve good aesthetic and functional results by malotravmatichnosti and reliability reposition of bone fragments.

1. Tool to reposition the zygomatic arches and bones, containing the handle and the working end in the form of a rod and two prongs, wherein the working part is made of titanium nickelide with the effect of thermoplate and consists of stable rod, bent at an angle of 20owith respect to the handle and part of that change shape in the form of teeth, which are made subulate, diverging at an angle of 30oand oriented towards a stable rod at an angle of 60o.

2. The instrument under item 1, characterized in that at the ends of the subulate teeth have
