This invention relates to medicine, in particular to surgical instruments.

A device is known which contains two pivotally connected spring-loaded branches having pens and shaped working sponges for gripping medical instruments.

However, the device does not allow to firmly hold the brace for osteosynthesis when inserting it into the bone, especially when the brace has a complex spatial configuration in different planes and is made of a material that has a shape memory effect that requires specific preparation. In addition, the pre-formed bone channels should correspond exactly to the legs of the brace. Failure to maintain the exact distance between the bone canals can make it impossible to install the brace or reduce the compression force and stability of the osteosynthesis.

The purpose of the invention is to reduce time and improve accuracy when installing an osteosynthesis bracket made of a material with a shape memory effect having a complex configuration.

Figure 1 shows the forceps, a general view; Fig. 2 is the same from the side of the base; in FIG. 3, a bracket for osteosynthesis.

The tongs contain two pivotally connected spring-loaded branches 1 having handles 2 and working jaws 3, are provided with a support unit 4 in the form of a rod 5 at one end 6 with a handle 7, and at the other 8 with a base 9 having grooves 10 and holes 11 for accommodating the staples, and working sponges 3 are made in the form of L-shaped forks 12 in contact with the base 9.

The device works as follows.

After processing the bone fragments intended for osteosynthesis and tight matching, the forceps with the base 9 are pressed tightly with one hand to the bones so that the through holes 11 are on opposite sides of the line of connection of the phage by the same distance. Through the holes 11 on the bones form channels. The holes 11 on the base 9 of the tongs are arranged so that they correspond to the position of the legs of the bracket in the working position. The brace for osteosynthesis, pliers and forceps are cooled with chloroethyl do. After that, pliers grab the bracket and give it a working form by straightening arcuate branches. Holding the forceps with the handle 7 with one hand, the surgeon with the fingers of the same hand presses the handles 2 of the branches 1, while the working jaws 3 of the branches 1 and the L-shaped forks 12 are moved away from the rod 5

-base 9.

Then the pliers clamp in the working position is installed on the base 9 so that the straightened curved halves of the bracket fully fit into the corresponding groove 10. The handles 2 of the branch 1 lower and the L-shaped forks 12 fit tightly to the surface of the base 9, closing the groove 10 and hold there is a bracket in it. The pliers straighten the legs of the staples. The surgeon with one hand aligns the bone fragments, with the other, holding the forceps with the bracket, inserts the legs of the bracket into the previously formed bone channels, tightly pressing the base 9 to the surface of the synthesized fragments. In the subsequent simultaneous clamping of the handle 2 branches 1 to the rod 5, the L-shaped forks 12 are pushed back and the groove 10 is released. The stops on the handles 2 branches 1 prevent

excessive discrepancy of branches 1 deep in the wound, which prevents tissue trauma. Forceps are removed from the glands. A staple installed in the bone canals, due to heating above 10 ° C, tends to accept

original form, carried out a stable compression osteosynthesis of bone fragments.
