Description

The utility model relates to medicine, and more specifically to medical equipment used to conduct an artificial vessel to perform reconstructive operations for obliterating diseases of the arteries of the lower extremities.

A known probe containing a rod of elastic material with olive at the working end (1).

The disadvantage of this probe is the increased invasiveness of its use.

A device for forming channels under the skin of a patient is known, comprising a body made of two connected U-shaped parts with a sharp tip (2).

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

A device for installing a prosthesis in a blood vessel containing a tubular guide is known. Tip and return spring (3).

This device cannot be used to form tunnels in body tissues.

Known surgical instrument containing a tubular shaft with a tip (4).

The disadvantage of this tool is the increased invasiveness of its use.

A device for tunneling is known, containing a conductor, a U-shaped expander, a drive gear mechanism, the conductor being made of two interconnected plates and a flexible rod (5).

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

A device is known for the formation of channels in biological tissues, containing a tubular guide, a control rod stem with a knife and a shank (6).

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

A device for equipping canals in tissues is also known, comprising a guide tube with an arcuate blade at the end (7).

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

The purpose of creating a utility model is to reduce trauma and increase usability.

This goal is achieved by the fact that a removable non-pointed tip is installed on the distal working end of the guide tube, a handle is installed on the proximal portion of the guide tube, and

the outer surface of the guide tube is a longitudinal pointer line, the device further comprising a probe conductor located in the inner channel of the guide tube and provided with a handle at the proximal end and a gripper at the distal end, and a longitudinal pointer line is made along the entire length of the probe conductor . The cross-sectional guide tube has an oval shape.

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. Figure 1 shows the proposed device, side view; figure 2 is also a top view; figure 3 shows the probe conductor, figure 4 is a section aa in figure 2.

The proposed device for tunneling contains a guide tube 1, in cross section having the shape of a circle or oval. A removable tip 2 is installed on the distal working end of the guide tube 1, and a handle 3 is located on the proximal portion of the guide tube. A longitudinal pointer line 4 is made along the entire outer surface of the guide tube 1. The device is additionally equipped with a probe probe 5 with a handle 6 on proximal end and grab 7 at the distal end. Along the entire length of the probe conductor 5, a longitudinal pointer line is made (not shown in the drawing).

A device for tunneling in order to conduct an artificial vessel is used as follows.

Determine the necessary parameters of the artificial vessel and the injection site of the device on the patient’s body. Holding the handle 3, the tip 2 is inserted into the area of proximal access to the artery along the vascular bundle, the guide tube 1 is drawn to the required distance and its working distal end is removed from the area of distal access to the artery by puncture. The removable tip 3 is removed and a probe conductor 5 is inserted into the proximal end of the guide tube 1, at the end of the probe conductor 5 emerging from the distal end of the conductor tube 1, the end of the artificial vessel is fixed by means of a gripper 7 and passed through the guide tube 1 located along the vascular bundle. Then remove the tube guide from the wound.

The passage of the artificial vessel through the guide tube 1 is visually controlled by the pointer line 4 and by the pointer line on the probe conductor 5. More precisely, the coincidence of these lines on the distal and proximal sections of the guide tube 1 and the probe conductor 5 eliminates the possibility of bending and twisting of the artificial vessel. After carrying out an artificial vessel, all the necessary manipulations are performed according to known methods.

The implementation of the guide tube 1 in the transverse segment in the form of an oval (see figure 4) eliminates the possibility of bending and twisting of the conducted artificial vessel. Capture 7 may be of any known design.

The proposed device is simple in design and reliable in operation. Its use allows to conduct an artificial vessel with minimal labor and trauma.

The utility model will find wide application in the practice of the work of angiosurgical units of medical institutions.
