Abstract

The utility model relates to the field of medicine. The purpose of the utility model is to reduce the complexity and trauma during the collection and destruction of the brain of the tubular bones. The device includes a rod with a handle and a working section of a spiral-shaped groove-shaped cross section and a guide tube with a side hole at the distal end. 2 pf, 7 ill.

Description

The case model belongs to the field of medicine, and more specifically to surgical devices used in surgical treatment of patients with arteriosclerosis obliterans of the lower limb arteries.

A device for taking bone marrow containing a body, a needle with a mandrel and an adjusting nut (1) is known.

The disadvantage of this device is the inability to use it to remove and destroy bone marrow in the tubular bones.

A device for marrow puncture is known, which contains a needle with a cannula and mandrin, a stop with a through channel and a support platform (2, 3).

The disadvantage of this device is the complexity of its use for the destruction of bone marrow of the tubular bones.

A device for extracting the contents of tubular organs, containing a rod with screw packing (4).

The disadvantage of this device is the increased trauma and the complexity of its use for the collection and destruction of the brain of the tubular bones.

A device for taking bone marrow containing a body, a needle with a cannula and a mandrin and a needle position lock (5) is known.

The disadvantage of this device is the increased complexity of its use in the destruction of the brain in the tubular bones.

It is also known a device for processing internal cavities of tubular bones, containing a rod with a handle and a working part made of an elastic flexible material (6).

The disadvantage of this device is the increased invasiveness and laboriousness during the collection and destruction of the brain of the tubular bones.

The purpose of creating a utility model is to reduce the morbidity and complexity during the collection and destruction of the brain of tubular bones.

This goal is achieved by the fact that the working section is made by a groove-shaped cross-section of a spiral shape with a spiral pitch 0.5-1.0 of the length of the working part, and the working section is equipped with a guide tube made with a blind distal end and a side hole, while the side wall of the hole from the side of the distal end of the guide tube is made at an angle to the longitudinal axis of the Central hole, and at the proximal end of the guide tube is a flange with an arrow indicating the location of the side hole.

Comparison of the proposed device with others known in the field of medicine, showed its compliance with the criteria of a utility model.

The utility model is illustrated by graphic material. In Fig.1 shows a rod with a working section; figure 2 is a section aa in figure 1; on

figure 3 is a section bB in figure 1; figure 4 shows a tube-guide in the context; figure 5 is a view along arrow B in figure 4; in Fig.6 is a view along arrow G in Fig.4; figure 6 is a variant of the use of the device.

The utility model includes a rod 1 with a handle 2 and a working section 3, made gutter-shaped cross-section (see figure 3) and a spiral shape with a spiral pitch of 0.5-1.0 length of the working part (see figure 1). The working section is equipped with a guide tube 4 with a blind distal end 5 and a side hole 6, while the side wall 7 of the hole 6 from the side of the distal end 5 of the guide tube 4 is made at an angle to the longitudinal axis 8 of the central hole 9 of the guide tube 4, and at the proximal end of the guide tube 4, a flange 10 is installed with an arrow-pointer 11 for placing the side hole 6 (see Fig. 4, Fig. 5, Fig. 6).

For the collection and destruction of the brain in the tubular bones, the device is used as follows (see Fig.7).

By a known method, an incision 12 of the surface B of the patient’s body is made. A hole 14 of the required diameter is made in the tubular bone 15. A guide tube 4 is placed in the hole 14. A lateral hole 6 is placed in the predetermined direction in the directional arrow 11. By slowly screwing the working section 3 by the handle 2, place it in the bone channel. In this case, the bone marrow is destroyed and placed in the spiral part of the working area. Remove the working section 3 from the guide tube 4 and repeat the process. If necessary, the lateral hole 6 of the picking tube 4 is installed in the opposite side of the tubular bone 15 and the process is repeated (see Fig.6). Since the working section 3 is made of an elastic flexible material, it easily passes through the pickling tube and changes its direction.

Using the proposed device allows with minimal labor and trauma to produce a fence and the destruction of the brain in the tubular bones.

The device is simple in design and reliable in operation.

The proposed device is advisable to use in the surgical units of medical institutions.
