Abstract

1. An osteotome containing a handle and a working element provided with a cutting part, characterized in that the handle and the working element are arranged in one longitudinal straight line, and the cutting part is made with uniformly spaced teeth along the entire length, with each cavity provided with a sharpening made at an angle to the longitudinal axis of the osteotome. 2. Osteotome according to claim 1, characterized in that on the osteotome handle a surface is made in the form of a hexagon.

Description

The utility model relates to regional medicine, namely, to surgical instruments used in orthopedics and traumatology, in particular to osteotomes for violating bone integrity.

A device for processing the surface of the bone, containing a handle and a working part with a notch, while the teeth of the notch have an angle at the apex of 40-60 °, located in a checkerboard pattern, with the adjacent rows of teeth having the opposite direction (A.S. 584853 USSR, publ. .25.12.77, bull. 47).

Known by an osteotome containing a handle and a working part with a cutting edge at the end and a protrusion on the side surface, in which the protrusion is made in the form of a pointed tenon forming a broken line with the cutting edge, the working part is provided with a side located along the working part from the side opposite to the protrusion (A Soviet Union 1360711, M1SI A 61 17/16. Osteotome. Published on December 23, 87 Bul. 47).

A device for corrective, osteotomy containing a bit with a handle and a working part in the form of a gutter, equipped with an additional bit with a working part in the form of a gutter and a handle, and the bits are set so that the convex surface of the gutter of one bit is in contact with the concave surface of the gutter of another bit , the handles are bent at right angles to the axes of the bits, and the convex and concave surfaces of both bits have corrugations (AS 865282 USSR, MKM A61B17 / 18. Device for corrective osteotomy. Publish. 09/23/81 . Byul.35).

However, the known device is designed to enable rotation of bone fragments in a given direction when the integrity of the bone is violated for

OCTEOTOM

elimination of the equinus deformity of the foot, and the corrugation of both bits discourage their strong connection with the bone. It is not intended for its use in violation of the integrity of bones of small sizes, in particular in children, because simultaneous introduction of chisels significantly destroys the bone and disrupts blood circulation in its fragments.

The objective of this useful model is to develop such an osteotome design that will allow you to dissect the small size of the bone in any direction, including at an angle, as well as prevent the formation of large fragments.

The problem is solved in that in the osteotome containing the handle and the working element is equipped with a cutting part, in which the handle and the working element are located along one longitudinal straight line, and the cutting part is completely filled with evenly spaced teeth, while each cavity is provided with a sharpening made at an angle to the longitudinal axis of the osteotome.

In addition, for convenience and safety of use during the implementation of the osteotomy, a surface in the form of a hexagon can be made on the handle of the osteotomy.

The proposed utility model is explained by a detailed description of a specific implementation example with links to the attached figure on which:

figure 1 depicts an osteotome with a cutting part equipped with teeth;

Figure 2 shows a sharpening depression.

The osteotome contains a working element 1 (Fig. 1) in the form of a plate or a segment of the lateral surface of the cylinder with a cutting part 2 and a handle 3. The cutting part 2 and the handle 3 are located along one longitudinal blind. On the cutting part 3, uniformly spaced teeth 4 are made. The depressions 5 (FIG. 2) are provided with a sharpening 6 made at an angle to the longitudinal axis of the osteotome.

The handle 3 (Figure 1) is equipped with a shock pad 7 and a surface made in the form of a hexagon 8.

The osteotome is used as follows.

In the operating room, while performing an osteotomy, a surgeon holding an osteotomy by the handle 3

(FigL), sets its working element 1 on the bone, if necessary at an angle and,

hitting a hammer on the strike pad 7, carries out the dissection of the bone. At indications

the surgeon only performs a bone incision, and then, having installed the key on the hexahedron 8,

rotation for it completes the violation of the integrity of the bone by osteoclasia.

The proposed osteotome allows you to dissect the bone in any direction, including at an acute angle, while the teeth of the cutting edge prevent slipping both from the bone and along it.

The use of this osteotome prevents the formation of large bone fragments, since the teeth of the cutting edge of the working part weaken the bone in the corresponding direction.

The use of this osteotome significantly reduces the concussion of the bone from being struck with a hammer, since it does not require excessive effort upon impact.

Osteotome is easy to manufacture and use. Used in clinical departments of the Russian Science and Technology Center. Acad. G.A. Ilizarova.
