Description

The utility model relates to the field of medicine, and more specifically to medical equipment, namely, devices designed to treat a wound surface in open surgical operations.

A known clamp containing two branches, which are curved, connected by a hinge axis, have rings for the fingers, handles and working parts in the form of clamping jaws. A longitudinal through groove is made on the clamping jaw of one of the jaws. Needle tabs are located on the clamping jaw of the other jaw. The needle protrusions have the ability to enter the groove of the jaw of the first jaw when the clamp is closed. The sponges are made with an elastic coating on the working surface (RF patent No. 2330624, А61В7 / 28, 08/10/2008).

However, it is inconvenient for use in small wounds.

Known surgical instrument, which consists of a working body with handles, housing, traction and springs. The spring is made compression-return and is connected at one end to a fixed handle and the other end through an axis to a movable handle. The second axis of the movable handle is the connection with the thrust of the working body (RF patent No. 2178992, A61B 17/00, 02/10/2002).

The disadvantage of this device is the unreliability of the fixation of abrasive material.

Known surgical instrument for tissue fixation, in which on the interconnected branches there are working parts in the form of a transverse plate and an arc that contains from 2 to 10 locking needles with a length of 2 to 10 mm. The needles are located at an equal distance from each other, oriented to the transverse plate and mounted on the transverse part of the arc, made in the form of a U-shaped limiter of the surgical field (RF patent No. 2107470, АВВ 17/122, 03/27/1998).

The disadvantage of this device is the inability to securely fix the abrasive material.

Known surgical instrument for holding and fixing tissues, which contains connected ends of the spring-loaded branches with a stopper and with working jaws located at an angle to the longitudinal axis of the branch. The working jaws have internal spikes and parallel radial surfaces in the form of guides of the cutting tool on the sides opposite to the branches. The working jaws are located transverse to the longitudinal axis and have parallel radius surfaces in the form of recesses made on the longitudinal axis of the jaw. The chord of the recesses is 1 / 8-2 / 3 of the length of the working jaws. The inner spikes have cross sections in the form of circles, or ovals, or polygons. (RF patent №2218884, АВВ 17/30, 12/20/2003).

The disadvantage of this device is the unreliability of the fixation of abrasive material.

A well-known surgical instrument, selected by the authors as a prototype, includes two curved handles - branches, which are connected by a lock and equipped with racks. Handles contain rings at one end and sponges at the other. One of the sponges on the back surface has a thrust plate for moving the second sponge above it. The plate is located on the convex surface of the sponge. A protrusion is made on the free edge of the plate to prevent the movable jaw from leaving the plate with optimal separation of the jaws. Sponges have cuts on working surfaces (RF patent No. 2193359, АВВ 17/16, 11/27/2002).

The disadvantage of this device is the excessive deformation of the abrasive material.

The technical result of the utility model is reliable fixation of the working element at the end of the device for better processing and stimulation of the reparative process.

The technical result is achieved by the fact that the device for treating infected wounds contains two branches connected by a hinge, equipped with a clamp, a ring is located at the lower ends of the branch, and a working part with a working element is located at the upper ends, and the device is additionally equipped with a cleaning roller, consisting of a hollow sleeve, inside which there is a freely rotating shaft, at the ends of which grooves are made, and the working part of the jaw is made in the form of two needle holders, the ends of which s are placed in the grooves of the rotating shaft, and the working element, made in the form of a spongy abrasive material, is removable and placed on the hollow sleeve.

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, where in FIG. 1 shows an assembly model of the device, front view in the working position; in FIG. 2 shows an assembly model of the device, front view in the initial position; in FIG. 3 shows an assembly model of the device side view.

A device for treating infected wounds consists of jaws 1 interconnected by a hinge 2, at the lower ends of the jaws there are rings 3 for fingers. The jaws are fastened with a cremeler lock 4. At the upper ends of the jaw there is a working part 5 made in the form of two needle holders 6. The cleaning roller consists of a hollow sleeve 7 inside which there is a freely rotating shaft 8, at the ends of which grooves 9 are made in which the needle holders 6 are fixed working part 5 of the device. On the surface of the hollow sleeve 7 is a removable working element 10 made in the form of a sponge abrasive material.

A device for treating infected wounds works as follows (Fig. 1). Pre-produce necrectomy of the wound, blunt and acute way. Then, for better treatment and stimulation of the reparative process, a device for treating infected wounds is used. The fingers are inserted into the rings 3 of the jaw 1, unclench the silicon retainer 4 and reveal the upper parts of the jaw. Preliminarily, a removable working element 10 is placed on the surface of the hollow sleeve 7 in the form of a spongy abrasive material 10. The freely rotating shaft 8 is fixed with the working part 5 by inserting the needle holders 6 into the grooves 9. The ends of the jaw are clamped, holding on to the rings 3 and fixed with a clamp 4 . Produce treatment of the wound surface. After processing, the spongy abrasive material is removed and disassembled in the reverse order.

Using the proposed device will ensure reliable fixation of the working element, reduce the complexity and improve ease of use. Provides complete and reliable cleaning, freedom of manipulation within the surgical field. Reliability and completeness of cleaning improves the working conditions of the surgeon, which, in turn, improves the quality and accelerates the course of surgery.

A device for treating infected wounds will be widely used in the surgical units of medical institutions.

Clinical example.

Patient A, 74 years old, down at the department of vascular surgery V.D. Seredavina 11/24/18 g with a diagnosis of Trophic ulcer of the right lower leg 11/25/18 performed surgery - necrectomy of the wound surface of the trophic ulcer. Operation progress: Dull and sharp paths excised and removed necrotic tissue from the wound surface of the trophic ulcer. To stimulate the reparative process in the wound of the proposed device for the treatment of infected wounds. The wound surface is carefully treated with a working element, drained, an atraumatic dressing is applied. The general condition of the patient is satisfactory. Examined on days 2, 5, 7 and 14 with a mandatory treatment of the wound surface with a working element, a device for treating infected wounds. Wound healing by secondary intention.
