    The subject of the invention is a surgical strut for treatment of the back-bone. The strut has a rod having a round cross section provided at one end with a number of through holes disposed perpendicularly to the rod axis. The axes of neighboring holes form an angle of 90 DEG . Said holes are aimed at fitting a pin fixing the position of the hook, mostly the pectoral one, mounted on the rod. Said hook is provided with a round hole the wall whereof is from the side of the front face provided with four recesses disposed on the periphery every 90 DEG , constituting the seats for the pin. In order to maintain a suitable elasticity the rods of the struts having the lengths smaller than 250 mm have a differentiated diameter the dimension whereof in relation to the rod length constitutes a ratio of 1:20 through 1:35. The hook co-operating with this section of the rod, mostly the lumbar hook, is provided with a blind hole wherein the rod end is supported.

    2. The distractor according to claim 1, d tl, which is based on the fact that the other hook is made with a blind hole along the rod.
    3. The distractor according to claim 1, characterized in that the ratio of the diameter of the rod to its length is made within 1: 20-1: 35.,
    The invention relates to medical technology, namely, a distractor for the surgical treatment of the spine, and can be used to treat scoliotic and nyphotic spinal curvature, especially in young people.
    A known distractor for the surgical treatment of the spine, containing a sliding rod with hooks mounted at its ends ti
    The closest to the invention according to the Technical essence and the achieved effect is a distractor for the surgical treatment of the spine, containing a round rod with hooks 123 mounted on it.
    A disadvantage of the known technical solutions is that their manufacture is laborious, they have a low elasticity and often burst on the patient's body, creating a danger to his health and life.
    The purpose of the invention is to simplify the design and increase its strength.
    The goal is achieved by the fact that in a distractor for surgical treatment of the spine, containing a round rod with hooks mounted on it, one end of the rod is made with through holes, the axes of which are perpendicular to the axis of the rod, a pin is installed in one of the holes the hooks are hollowed out for the pin.
    In addition, another hook is made with a blind hole for the rod, and the ratio of the diameter of the rod to its length is performed within 1: 20-1: 35
    FIG. 1 shows a distractor for surgical treatment of the spinal column, side view; in fig. 2 is a hook section} in FIG. 3 - section of the rod in place
    the passage of the pin; in fig. 4 narrowed distractor, side view.
    The spine surgical dissector contains a round rod 1 with hooks mounted on it for lumbar 2 and chest 3. At one end of rod 1 from the chest hook 3 there are through holes 4, the axes of which are perpendicular to the axis of the rod axis, 1, and
    0 of the holes 4 is installed pin 5, and the holes themselves are arranged in a checkerboard pattern. The chest hook 3 has, on the front side in a plane perpendicular to the axis, four mutually
    5 perpendicular grooves 6 under the pin.
    In the narrowed distractor, the lumbar hook has a blind hole 7 for the rod 1.
    0
    The ratio of the diameter of the rod 1 to its length is 1: 20-1: 35.
    Hooks 2 and 3 are bent-. 8, which are used to mount the device in an instrument holder for
    5 distraction.
    A distractor is used as follows.
    After skin incision and exposure from one side of the spinous processes,
    0 arcs, articular processes of the vertebrae, forming a curvature, begin to install the distractor. The installation locations of the hooks 2 and 3 are the border vertebrae. A hook 3 is inserted on the upper border vertebra, a hook 2 is inserted on the lower border. Depending on the length of the curvature site, the hook 3 is moved. on the rod 1 and fix it with the help of the pin 5 entering the recesses b on the hook 3.
    0
    Thus, the invention makes it possible to adjust the length of the patch to be adjusted simply and firmly.
