The invention relates to medicine, namely to traumatology and orthopedics.

An intraosseous fixator for the treatment of fractures of long tubular bones is known, which contains an empty hollow body with lobes in the form of lobes and a rod with conical protrusions and thrust pads 1

However, in the limestone Ustronstze, in order to ensure stable fixation of bone fragments, its use requires the longitudinal reaming of the medullary canal. Ch7o increases the amount of operating surgery.

The aim of the invention is to provide stable fixation of bone fragments by maintaining postchal pressure on the wall of the medullary canal and reducing trauma.

The goal is achieved by the fact that in intraosseous phi: a catcher for the treatment of fractures of long tubular bones, containing sosociu: fixed hollow body with fixation in the form of petals and a rod with conical protrusions and useful platforms K01- a ledge; mounted on a rod with a capacity i displacements ;, with a rod snpg: women cylindr1: scam springs, mouth ,; new but a mixture of conical projections h persistent; 1 7;

After splicing of the fragments, the retainer is removed.

The proposed fixer provides physiological conditions for the repair of bone fragments in various types of fractures: oblique, helical, comminuted, transverse, since the petals act on the walls of the bone canal along the Bceft to its length in three planes, taking into account the individual characteristics of the bone marrow channel, while ensuring reliable fixation of bone fragments
