The invention relates to medical technology, namely to surgical instruments.

The purpose of the invention is to increase the speed of application of surgical instruments.

FIG. 1 shows a clip, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 is a view B in FIG. one; in fig. 4 is a view of B in FIG. one; in fig. 5 - gearing of the sleeve with the branch and the rod.

The lock for surgical instruments consists of two branches 1 and 2 with ring handles 3 and 4, stem 5, handle 6, bushings 7 with protrusions 8 and grooves 9 made in its opening, longitudinal groove 10 on stem 5, through openings 11 on the sleeve 7, a spacer in the form of a wedge 12 with a spike 13, a support bar 14, a limiting flap 15 in the form of a flat bar.

At the same time, the larger base of the groove 10 is edged towards the annular handle 4. At the end of the rod 5 there is a flange 16, on the rod 5 there are two parallel bevels 17. In the branch 2 a through hole 18 is made. In the opposite walls of the sleeve 7 they are made coaxially one a hole 11, the configuration of which can be of any shape, for example conical, whose longitudinal axis is in the same plane with the longitudinal axis of the hole 18, the holes of the sleeve 7, the longitudinal axis of the wedge 12 and the longitudinal axis of the rod 5 and the longitudinal conical groove 10, and small Starting through the tapered holes 11 faces the sponge. The support bar 14 is located in the clamping part, between the ring handle 4 and the sleeve 7, in which a longitudinal groove 19 is made, the longitudinal axis of which is parallel to the inner surface of the branch 2, under the spike 13 of the spacer element made in the form of a wedge 12, whose working surfaces can be any profile, for example, smooth, on the peripheral part of the support bar 14, on the side of the annular handle 4, a restrictive valve 15 is installed in the slots 20, the alternating protrusions 8 and the depressions 9 being made in the opening 18 coaxially with the opening of the sleeve 7.

The lock is assembled in the following sequence: using the tweezers, the rod 5 is clamped with the left hand and the ends connected to it are inserted into the opening of the sleeve 7 and into the opening 18. The flange 16 is removed as well. , then the spike 13 of the wedge 12 is inserted into the groove 19, from the side of the annular handle 4, after which the restrictive flap 15 is inserted into the grooves 20 from above.

The lock is used as follows.

For the moment of the operation, the clamp is taken in the right hand, disclosing defects 1 and 2, as a result of which the rod 5 passes unhindered inside them, making a stepless movement of the rod, and as a result, ensuring the stepless operation of the clip, which is facilitated by two parallel bevels 17 on the rod 5. The rod 5 is fixed against the branch 2 by inserting the wedge 12 with the handle 6 until the lugs 8 and the cavities 9 of the opening of the sleeve 7 and the branch 2 interact.

Claims (5)

1. A lock for surgical instruments, consisting of two pivotally connected branches, on one branch, on its inner side, there is a rod passing through a sleeve installed on the other branch, and a stopping element, characterized in that, in order to increase speed Surgical instruments are placed on the rod, in the sleeve and in the hole in the branch, alternating protrusions and depressions are made, a longitudinal groove is made on the rod, in the opposite walls of the sleeve, one coaxially through hole, the longitudinal axes of which are one in the same plane with the longitudinal axes of the axial bore of the sleeve coaxial with it the through hole in the branch, with the longitudinal axes of the rod and the spacer in the form of a wedge with a handle that is placed in the holes made in the walls of the sleeve and the groove of the rod the supporting part of the wedge is made in the form of a pin located in the corresponding longitudinal groove made in the support plate connected to the branch on its inner side, in the support plate in its peripheral part on the side of the annular handle Positive damper. 2. The lock according to claim i, characterized in that, in order to securely fix the wedge in the groove of the rod, the rod is made elastic. 3. The lock according to claim 1, characterized in that, for the purpose of the stepless operation of the tool in a larger branch solution, two parallel bevels are made on the rod, facing the sponge and toward the non-working part of the branch. 4. The lock according to claim 1, characterized in that, for the purpose of ease of manufacture, the projections and depressions are made in the form of a thread of a triangular profile having the same clamp. 5. The lock according to claim 1, characterized in that, in order to prevent the rod from falling out of the holes in the sleeve and in the branch, at the end of the rod there is a flange whose diameter is larger than the internal diameter of the through hole of the sleeve and coaxial with it in the branch. . one/ // 15 / AT 5 ± 3.
