The device comprises a cylindrical body and a cutting element, wherein a cutting edge is made at the distal end of the body, a threaded section is made on the distal part of the body, on which a threaded support washer is installed, the working end of the body is made with a tapered thread, and a thread is made on the proximal end of the body, on which a threaded sleeve with a tapered axial bore corresponding to the syringe cannula is installed.

Description

The utility model relates to medicine, and more particularly to surgical instruments used to perform osteoperforation of tubular bones in the treatment of patients with obliterating diseases of the arteries of the lower extremities.

A device for processing bone tissue containing a shaft with a cutting part fixed on it, made in the form of a spiral (1).

The disadvantage of this device is the increased trauma during osteoperforation of the tubular bones.

A device for processing bone tissue, comprising a body, a central shaft and two coaxially placed milling cutters (2), is known.

The disadvantage of this device is the inconvenience of use, increased design complexity and the possibility of injury to surrounding tissues.

A device is known for forming holes in bone tissue, comprising a body and a working element (3).

The disadvantage of this device is the increased invasiveness and inconvenience of use during osteoperforation of the tubular bones.

A device for drilling bones containing a working element and a drive (4) is known.

The disadvantage of this device is the increased complexity of the design and the invasiveness of the surrounding tissues.

A device for drilling bones containing a body and a working element (5) is known.

The disadvantage of this device is the inconvenience of use and the possibility of injury to surrounding tissues.

A device for drilling bones is known, comprising a body with a conical bell, a working tool, a drive and a base in the form of a disk with slots (6).

The disadvantage of this device is the increased complexity of the design and inconvenience of use.

A bone perforator is also known, comprising a cylindrical body and a cutting element (7) located therein.

The disadvantage of this device is the increased complexity of use and the possibility of injury to surrounding tissues.

The purpose of creating a utility model is to reduce the complexity of the use and trauma of surrounding tissues.

This goal is achieved by the fact that the working end of the housing is conical in shape and provided with a tapered thread, the end of the housing is made with a toothed cutting edge, on the distal part of the housing

a threaded portion on which a threaded support washer is mounted, wherein a thread is made on the proximal portion of the housing, on which a threaded sleeve is installed with an axial conical bore corresponding to the syringe cannula.

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

The utility model is illustrated by graphic material. Figure 1 shows the proposed device, a General view; figure 2 shows the proposed device, a General view without a cutting element.

A device for osteoperforation of tubular bones comprises a cylindrical body 1 in which a cutting element 2 is located with a pointed working end 3 at the distal end and a handle 4 at the proximal end. The working end of the housing 1 is made conical in shape and provided with a taper thread 5. The working end of the housing 1 is made with a cutting gear edge 6. On the distal part of the housing 1 there is a threaded section 7 on which a threaded washer is mounted.

A handle 9 is fixed on the proximal portion of the housing 1. A thread 10 can be made on the proximal end of the housing 1, on which a threaded sleeve 11 with an axial conical bore 12 corresponding to the syringe cone is installed.

The proposed device for osteoperforation of the tubular bones is used as follows.

An incision is made in the patient’s skin at a given location. The assembled device (see Fig. 1) is inserted into the wound and, by rotating the cutting element 2 by the handle 4 with a pointed working end 3, a channel is formed in the bone. Then, by rotation for the handle 9, screwing and fixing into the oblique fabric of the housing 1 is carried out using a threaded cutting end 6 and taper thread 5. The cutting element 2 is removed from the housing 1. A channel is formed in the next place with a similar device. Remove the cutting element. A sleeve 11 is installed on the thread 10 of the housing 1. A syringe plug (not shown in the drawing) with a washing solution is installed in the conical hole 12 of the sleeve 11. The contents of the syringe are squeezed into the bone cavity. The bone marrow will be squeezed out of the second formed opening.

When installing the body 1 in the bone tissue 6, the conical thread 5 at its distal end allows you to securely fix the body 1 in the bone tissue, preventing it from escaping from the bone and excluding the possibility of muscle tissue being drawn into the bone canal, which in turn eliminates the possibility of additional trauma.

Using the proposed device reduces the complexity of osteoperforation of the tubular bones and trauma to the surrounding soft tissues.

The device is simple in design, requires minimal labor and is reliable to use.

The device can and should be used in angiosurgery units of medical institutions for osteoperforation of the tubular bones in the treatment of obliterating diseases of the arteries of the lower extremities.
