The invention relates to medicine, namely to devices designed for tightening ligature nodes.

A known tool for tightening the ligature assemblies, comprising a handle and a stand with a flat tip, is equipped with guide bore grooves Cl J.

However, when the double knot is tightened with a known tool, the previous loop weakens when the next loop of the knot is tightened.

The purpose of the invention is to prevent the precursor loop from loosening when the subsequent loop of the assembly is tightened.

This goal is achieved by the fact that in the tool for tightening the ligature units containing a handle and a stand with a flat tip, provided with guide side grooves, the rod with the end is mounted with the possibility of longitudinal movement of the rod with the end bent toward the tip.

FIG. 1 shows a tool for tightening ligature units, general view; in fig. 2 is a view B in FIG. one; on r. 3 - section A-A in FIG. 2} in FIG. 4 - curved end of the rod; in fig. 5 - knot tightening.

The tool for tightening the ligature assemblies consists of a flat tip 1 having ends at the end and guide grooves 2 on the sides, and an upper strap 3 connected to tip 1 by racks 4 and 5. The fixing rod 6 has a handle 7 at one end, and at the other end bent end 8. A guide bush is placed between the pillars 4 and 5

9 with an internal key, mounted on axles 10 connected to the uprights 4 and 5. A spring 11 and a finger rest 12 are attached to the strap 3.

On the plank 3, between the fasteners of the pillars 4 and 5 there is an elongated cut-out 13. The rod 6 is passed through the sleeve

9 and a recess 13, and the spring 11 presses the rod to the edge of the bar 13 near the tool axis. The bent end 8 of the bar 6 is pressed to the tip 1 so that it enters the notch of the end of the bar.

 The tool is used as follows.

The free ends of the ligature tie the first loop. Plant the ends of the ligature into the side guide grooves 2 of the tip 1 and push the loop forward, simultaneously pulling the ends of the ligature, while the tip 1 and the rod 6 are closed. When the loop is advanced up to the stop in the fabric and tucked, it is held with the bent end 8 of the rod 6, pressing the handle 7, simultaneously acting on the stop 12, pull tip 1 upward and release the ends of the ligature from the grooves 2. Leaving the loop pressed, the second the loop, again, the ends of the ligature are cut into the grooves 2 of the tip 1 and tie the second loop to jraop 1. Then the rod 6 is retracted to the side, overcoming the resistance of the spring 11, until it reaches the edge of the cutout 13 of the bar 3. comes out of the notch on the end of the tip 1 and from the loop. Clamp tip 1, pull the ends of the pigment and finally tie the knot.
