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.

Known clip 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, АВВ 17/28, 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 interconnected branches have working parts in the form of a transverse plate and an arc that contains from 2 to 10 stop needles from 2 to 10 mm long. 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 tool 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.

Known surgical instrument, selected by the authors as a prototype, including two curved branches-jaws, 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.

Analysis of existing devices for treating wound surfaces showed that none of them can be a prototype for the design of the device proposed by the authors.

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 in that the device for treating infected and purulent-necrotic wounds contains a housing in which the handle of the cleaning roller is located, a plastic tube with a flexible configuration for feeding an antiseptic and a plastic suction tube with a flexible configuration. In the upper right part of the handle of the cleaning roller there is a stop, then the working part is located, and on the opposite side there is a removable threaded stop-clamp. The working part of the device is a cleaning roller, which consists of a cylinder on which sponge abrasive material is located. A plastic tube with a flexible configuration for feeding an antiseptic is made with a gradient of decreasing the cross section from larger to smaller and is located on one side of the cleaning roller, while the end of the tube is plugged, and on its shower part there are holes for irrigation of spongy abrasive material with an antiseptic solution. A plastic suction tube with a flexible configuration is located on the other side of the cleaning roller, and there are perforation holes in the suction section to draw in the wound wash water.

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, side view, in the working position.

A device for treating infected and purulent-necrotic wounds contains a housing 1, in which the handle of the cleaning roller 2 is located. In the upper right part of the handle of the cleaning roller 2 there is a stop 3, then there is a working part 4, on the left side there is a removable threaded stop-clamp 5. The working part itself is a cleaning roller 2, which consists of a cylinder 6, on which a sponge abrasive material 7 is located. In the housing 1 passes a plastic tube 8 with a flexible configuration for feeding an antiseptic ka, made with a gradient of decreasing the cross section from larger to smaller, which is located on one side of the cleaning roller 2. The end of the tube 8 is plugged, and on its shower part 9 there are holes 10 for irrigation of the sponge abrasive material 7 with an antiseptic solution. Also in - the housing 1 passes a plastic tube-suction 11 of a flexible configuration with a suction part 12, which is located on the other side of the cleaning roller 2. In the suction part 12 there are perforation holes 13 for collecting wound wash water.

A device for treating infected and purulent-necrotic wounds is used as follows (Fig. 1). Pre-produce necrectomy of the wound in a blunt and acute way. Then the device is connected to a dropper with an antiseptic solution and a suction. The device is taken by the housing 1 and at the same time they turn on the supply of an antiseptic, connecting the tube 8 and the suction, connecting the suction tube 11. Sponge abrasive material 7 starts to be irrigated with the antiseptic 10 from the holes. The wound surface is processed. Perforation holes 13 of the suction part 12 is the abstraction of the wash water of the wound. The wound is cleansed. The device is disassembled in the reverse order.

Using the proposed device reduces the complexity and improves ease of use, provides a complete and reliable cleaning, freedom of manipulation within the surgical field. Reliability and completeness of cleaning improves the surgeon's working conditions, which, in turn, allows to improve the quality of treatment and accelerate the course of surgery.

A device for treating infected and purulent-necrotic surface wounds will find wide application in the surgical units of medical institutions.
