SU649416A1 - Implement for tightening ligature nodes - Google Patents

Description

one

The invention relates to medical technology, in particular to surgical instruments.

The known tool for tightening the ligature assemblies comprises spring bravshi and movably connected to the daisy rod with a notch on the floor 1.

The disadvantage of such a tool is that the second loop of the knot is inserted into the tool during opening, and then the rod with the ends of the ligature and the second loop is moved to its original position until the jaw is closed. At the same time, the time of filling with a ligature of the tool increases and the time required for tightening the ligature knot increases.

The aim of the invention is to reduce the time of inserting the ligature into the tool.

This goal is achieved by the fact that one of the branches is made with the possibility of longitudinal movement relative to the other. The rod on the side surfaces at the end has guiding split rings with inward-curved ends.

FIG. 1 shows the proposed tool with closed branches, a longitudinal section; in fig. 2 is a section A-A in FIG. one; in fig. 3 - tool, view

from the side; Fig. 4 is the same, longitudinal section with raised movable branch.

The tool contains spring branches 1 and 2, the rod 3 movably connected to them with a notch on the end face 4. The branch 2 is made with the possibility of longitudinal movement relative to the branch 1. On the lateral surfaces of the rod 3 at the end face there are guiding split rings 5 and 6.

When applying the ligature with the elongated ends 7 at a distance from the wound site, loops 8 and 9 are alternately pressed. Loop 9 is inserted into the tool. In this case, the branch 2 is in the raised position (Fig. 4). Then, branch 2 is brought to the position in which both branches are closed (Fig. J, 3).

The ends 7 of the ligature are threaded into rings 5 and 6. Tension the lugs of the ligature 7 with the aid of a tool and immerse the loops in the depth of the wound. Stretch the loop 8, then, moving the rod, push the branches and tighten the loop 9.

Thus form a knot.

The tool is removed from the wound.

The tool allows you to quickly, atraumatic and securely put a knot on the fabric in the hard-to-reach areas of the surgical floor.
