Abstract

The invention relates to medical technology. The purpose of the invention is to reduce trauma when approaching the edges of the wound. The device contains threaded rods 1 and 2 with openings 3. Rods 1 and 2 are connected by rods 4 and 5 through bosses 6 and 7 with help and lock nuts. Rods 4 and 5 through springs 8 and 9 are interconnected by bushings 10 and 11 with nuts 12 and 13. The holes 3 fix the ends of the needles 14 by tightening nuts 15. The assembled unit for skin distraction is mounted at the edge of the wound, produced simultaneously The insertion of needles into the skin into the skin, the height of their insertion, is regulated by lowering or raising the support legs 16. A sleeve 11 with a spring 9 and a nut 13 is put on the straight end of the rod 4. A similar assembly is mounted at the other end of the wound. 1 3. p. F-ly, 2 ill.

The invention relates to the medical technology I, namely to traumatology and surgery.

The aim of the invention is to reduce the morbidity with the approach of the wound edges.

FIG. 1 shows a device for the distraction of skin and soft tissues ;; in fig. 2 is a section A-A in FIG. one.

The device contains two threaded rods 1 and 2 with holes 3, which are perpendicular to their axis at the same distance. In the middle part of the threaded rods 1, 2 are connected by rods 4, 5 through the lugs 6, 7 using locknuts. The straight ends of the rods 4, 5 through springs 8, 9 are interconnected by sleeves 10, 11 with the help of nuts 12 and 13, in the hole 3 of the threaded rods 1, 2 the ends of the needles 14 are fixed by tightening the nuts 15, - The tips, located at the ends of the threaded rods, are attached to the ends of the support legs JQ.

16 tighter nuts 17.

The installation of a device for skin distraction and soft tissue distraction is different and is carried out in separate units. The assembled assembly includes a threaded rod 1, a rod 4 with a welded boss 6, needles 25 14 fixed by tightening nuts 15 (the number of exciting hooks depends on the length of the wound and is installed in the holes of the threaded rods 1 at a distance of 25-30 mm). In this case, the height of attachment of the rectilinear sections of the needles 14 in the hole x 3 of the rod 1 is determined by the skin relief of the wound edge. Thereafter, straight holes of the support legs 16 are installed in the holes located at the ends of the rod 1 and secured with nuts

17 until light fixation, preventing them from falling out. After assembly, the assembly is mounted at the edge of the wound, the needles 14 are simultaneously inserted into the skin, their height is adjusted by lowering or lifting 3 holes of the supporting legs 16, 40 into the holes, under which ends the gauze balls are laid, followed by

their stitching interrupted sutures to the skin. After that, a sleeve 11 between the rod supports with a spring 9 and a nut 45 is put on the straight end of the connecting ipangi 4. From the opposite end of the wound, a similarly assembled unit is mounted in a similar way. Then, a straight-line portion of the rod 5 is drawn into the sleeve 10 of the interstrip support;

The spring 8 tightens the nuts 12 and 13 to create a primary tension on the skin.

The installation of the device for the distraction of soft tissues is also carried out in separate units, but with previously removed needles 14, which are inserted into the soft tissues separately. An indent from the edges of the wound, previously commensurate with the distance between the apertures 3, on the rods x 1, 2, marks are applied to the skin. After the skin has been punctured, the needles 14 are successively inserted into soft tissues, with the exciting part of them being fixed to rigid anatomical formations of soft tissues — aponeurosis, fascia, and fascia joints. After that, for each row of needles 14 a separate unit is mounted with their fixing by tightening nuts 15 with the subsequent connection of the units.

The device works as follows.

The approach of the wound edges during the distraction of the skin and soft tissues is due to the metered rotation of the nuts 12, 13 on the rods 4 and 5, which provides the necessary compression of the springs 8 and 9, which ensure the approximation of the device assemblies with the skin or soft tissues. After loosening the springs 8, 9, nuts 12, 13 are tightened in succession until the edges of the wound approach. After the end of the distraction and signs of adhesion of the wound edges, the device is disassembled, with the nodes first being disconnected, followed by loosening the legs 16, removing the needles 14.

Claims (2)

1. A device for distraction of skin and soft tissues, comprising a body with needles installed therein so that they can be removed, a distraction mechanism, characterized in that, in order to reduce the trauma when the wound edges approach, the body is made in the form of two threaded rods with nuts and holes, in which needles are inserted, and the distraction mechanism is made in the form of two shtangs, the curved part of which is rigidly connected to a threaded boss placed on a threaded rod, which are interconnected by a threaded spring-loaded sleeve street nuts, and on the ends of the threaded rods are installed supporting legs. 2. A device according to claim 1, characterized in that the needles are curved sickle-shaped at an angle. 4 -A Fa G. 2
