The jaws are mounted in the same plane as the pressure plates and are equipped with tires with a tread-drain. Tires are mounted on the outside. The tread-drainage is made in the form of a strip of hygroscopic material, which is placed on the tires of the branch. The strip is impregnated with an antiseptic.

The disadvantage of this device is the lack of reliability of fixing adjacent tissues;

There is a method of treating purulent wounds according to Izmailov-Beschastnov (Russian Federation Pat. No. 2299024, A61B 17/04, 05/20/2007). A device is applied to the edges of the wound to bring together the edges of the wound. After surgical treatment of the wound, foam rubber is placed in its cavity, impregnated with an antiseptic solution and modeled on the shape of the wound. The edges of the wound are temporarily dosed for 12 hours by the device. Bred after 12 hours, the edges of the wound device. Remediation of the wound. The edges of the wound are reduced for 12 hours by the device. Repeatedly repeating the extension of the wound edges, debridement and rapprochement of the wound edges with the device until the wound cavity is completely cleansed. Remove the foam. Suture.

The disadvantage of this device is the presence of a gaping wound, which leads to pronounced cicatricial changes in the surrounding tissues, which subsequently makes it difficult to compare the edges of the wound defect and sharply worsens the cosmetic characteristics of the treatment results.

наружного диаметра канала.A device is known for minimally invasive debridement of purulent cavities (RF patent No. 2262353, АВВ 17/02, 20.10.2005). The device comprises a tube with holes and a cylindrical conductor. The distal section of the tube is equipped with measuring marks. The proximal end of the tube ends with an olive, to which a ligature is attached. The ligature and the tube are made with the possibility of conducting through separate channels of a cylindrical conductor and with the possibility of fixation. The tube is made with the possibility of bending during traction for the ligature and is divided into 2 channels. One channel of the tube serves to supply an antiseptic solution under pressure and is equipped with valves. Another channel is designed to evacuate the fluid from the abscess cavity and has evacuation openings the size of

the outer diameter of the channel.

The disadvantage of this device is the lack of effectiveness of the rehabilitation of the residual cavity of the abscess, especially in the treatment of large abscesses and the presence of intracavitary pockets.

A known method for the metered closure of wounds of the extremities with skin defects and purulent complications (RF patent No. 2372865, A61B 17/56, 11/20/2009). The device works as follows: Kirchner spokes are carried out in the area of healthy tissues along the edges of the wound. In places where the knitting needles reach the surface of the skin, under the knitting needles are ribbons of cuffs. Insert the ends of the tapes into the locks and tighten to the required tissue tension. As the wound heals, a metered approach of its edges is carried out by tightening self-locking plastic cuffs. The method provides a convenient, metered, uniform approximation of the edges of the wound of any configuration, with correction of its circumference and the full adequacy of all layers of soft tissue of the wound.

The disadvantage of this method is the use of the device is possible only on skin with severe subcutaneous tissue, which limits its use on the limbs.

Analysis of existing devices and methods for treating wound surfaces showed that none of them can be a prototype for the design of the device proposed by the authors for the treatment of extensive purulent wounds.

The technical result of the invention is to increase the effectiveness of the treatment of extensive purulent wounds by fixing skin flaps and reliable information of the edges of the wound, ensuring complete debridement, good access and review of the surgical wound.

A device for treating extensive purulent wounds consists of a proximal, median and distal half rings, with slotted openings for belts made at the ends of the proximal and distal half rings and cylinders for the drainage system installed vertically at the proximal end and horizontally at the distal end. The half rings are located on telescopic spokes, between which an elastic plastic stop is installed between the proximal and distal ends. Slides with grooves are fixed on the half rings on both sides, in which telescopic spokes with threaded holes are located, where through one the shock absorbing wound holders are inserted, which are a body with a freely rotating cylinder and with an adjustment handle in the upper part, and a working half ring is located in the lower part, on which they put on a rubber shock absorber, on which, in turn, put on a ligature, which is sewn through the shock absorber to the edge of the wound.
