Description

The utility model relates to medicine, namely to otorhinolaryngology and can be used to remove hypertrophic tissues in the treatment of sinusitis.

The closest technical solution is a device for the treatment of chronic rhinitis, containing a body made in the form of a tube. Three windows with cutting edges are made in the wall of the working end of the tube, which are evenly spaced around the circumference of the tube in the immediate vicinity of the end face, which is plugged and rounded. At the other end of the tube there is a fitting connected to the vacuum pump of the suction device by means of a rubber tube. The fitting serves simultaneously as the handle of the device. Windows have a length and a width, the ratio of which to the diameter of the tube is 2: 1 and 0.7: 0.8: 1. (Patent RU No. 2240061, M. AB61B 17/24, 07.24.2003.

A disadvantage of the known device is that the end of the straight tube is plugged, rounded and it is surgically impossible to remove pathological tissues from the paranasal sinuses.

The objective of the utility model is to create a device for surgical treatment that allows you to remove pathological tissues from the paranasal sinuses and to exclude possible complications after surgery.

The problem is achieved in that in a device for the surgical treatment of sinusitis containing a metal tube made with the possibility of connection by means of a rubber tube with a fitting of a vacuum pump in an aspiration device, new is that on the outer surface of the metal tube there are two through holes in which are installed nozzles, a metal tube and nozzles are connected to silicone hoses, valves and nozzles in the form of metal tubes with external diameters equal to 3.5-4.0 mm, internal diameters of 3.0-3.5 mm and inside with cutting edges 2.0-2.5 mm high at an angle of 45 ° around the circumference, on the first hose the nozzle is made curved in the form of an arc at the end at an angle of 90 °, on the second hose the nozzle is made curved in the form of an arc at the end at an angle of 135 °; on the third hose, the nozzle is made at the end in the form of a straight tube.

Bending the nozzle at an angle of 90 ° allows you to enter the fronto-nasal pocket and remove pathological tissues along the entire perimeter of the pocket with a cutting edge. Bending the nozzle at an angle of 135 ° allows the nozzle to enter the maxillary sinus and remove pathologically altered tissue using the cutting edge from the upper, front-outer sinus wall and lower sinus wall. A direct nozzle is inserted into the cells of the ethmoid labyrinth and allows you to remove tissue along the edges of the labyrinth and in the posterior part of the maxillary sinus.

During the operation, pathologically altered tissues are removed from the cells of the ethmoid labyrinth with a device with a straight tube nozzle. Tissue removal from the maxillary sinus through the anastomosis is carried out in the posterior sinus by a device with a nozzle at an angle of 135 °. In the lateral and anterior sections of the maxillary sinus perform device with a nozzle 90 °. All stages of the surgical operation are carried out sequentially and the nozzles on the hoses do not change. The ends of the nozzles are made with cutting edges at an angle of 45 ° for the effective removal of pathological tissues along the circumferences of the ends of the nozzles.

A device for the surgical treatment of sinusitis consists of a metal tube 1. On the outer surface 2 of the tube 1 there are two through holes 3 and 4, in which the nozzles 5 and 6 are installed. The tube 1 and the nozzles 5 and 6 are connected to silicone hoses 7, 8, 9, valves 10, 11, 12 and nozzles 13, 14 and 15. The nozzles 13, 14 and 15 are made in the form of metal tubes with external diameters of 3.5-4.0 mm, internal diameters of 3.0-3.5 mm and inside with cutting edges 2.0-2.5 mm high at 45 ° angles. On the hose 7, the nozzle 13 is made curved in the form of an arc at the end at an angle of 90 °. On the hose 9, the nozzle 15 is made of a curved arc at the end at an angle of 135 °. On the hose 8, the nozzle 14 is made at the end of the tube 1 in the form of a straight tube. The fitting 16 is connected by means of a rubber tube 17 to a vacuum pump 18 in an aspiration device.

The device operates as follows. During the operation, pathologically altered tissue cells of the ethmoid labyrinth are removed with the device with nozzle 14. Tissues from the maxillary sinus through the anastomosis in the posterior sections are removed with the nozzle 15. In the lateral and front sections of the maxillary sinus, pathologically altered tissues are removed with the device with the nozzle 13. All stages of the surgical operation perform sequentially with three nozzles. The inventive utility model is illustrated by drawings where:

in FIG. 1 shows a General view of the device;

in FIG. 2 shows a view of the I section of the end sections of the nozzles

in FIG. 3 shows a view of a II tube with two nozzles and with hoses;

The technical result of the proposed device for the surgical treatment of sinusitis is: effective removal of pathological tissues from all walls of the ethmoid labyrinth, maxillary sinus and fronto-nasal pocket; the device allows you to remove pathological tissues, hemorrhagic sinus contents. The proposed device for the surgical treatment of sinusitis can reduce the time for operations by half.
