SU1225557A1 - Apparatus for osteosynthesis - Google Patents

Description

The invention relates to medicine, namely to traumatology and orthopedics, and is intended for the osteosynthesis of small spongy bones, such as the bones of the foot or the foot.

The purpose of the invention is the provision of continuously-stressed osteosynthesis of small spongy bones.

FIG. 1 shows an osteosynthesis device, general view; in fig. 2 is a section A-A in FIG. one.

The device comprises a housing 1 and parallel needles 2 and 3 installed therein, which freely move therein and have stops 4 and 5. The housing 1 has a lock 6 of the needle 2. Loop 7 is formed on the spoke 1, and the stop 5 is separated from its end. The needle 2 is installed in the loop 7 of the needle 3 and on it is located a spring 8 and washers 9. The spring 8 rests, on the one hand, into the housing 1, and on the other - into the loop 7 of the spokes 2.

The device works as follows.

After the needles 2 are pinned through the fragments of the fine spongy bone, until the stop 4 is pressed, the distal end of the spokes is clipped with the stop 4, and it sinks under the skin. It is advisable to hold the spokes

perpendicular to the fracture plane of the bone. In parallel with the needle 2, the needle 3 is inserted until it stops 5 in such a way that the loop 7 covers the needle 2. The needle insertion point 3 is located near the exit point of the needle 2. To prevent rotational displacements of the bone fragments, the needle 3 passes its edge through to prevent injury to the articular surfaces of the bone, this point should not extend beyond the bone. On the needle 2, a calibrated compression spring 8 with shields 9 is put on, then case 1 is put on the free ends of both spokes.

 so that the spokes pass through two parallel through holes on the faces of housing 1. With the help of a spun givatel, the spokes 2 are tensioned and the spring 8 is compressed. After the compressive force reaches the desired value, the spoke 2 is fixed in housing 1 with clamp 6. The end of the spokes 3 freely passes through the hole in the housing 1.

Compression is kept constant by spring 8.

If the tension of the spring weakens during the treatment, it is further tightened.
