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 device for treating a wound surface is known, which contains a shank and a head with an abrasive coating from the drug Ximedon. The size and shape of the head is chosen depending on the area and topography of the processed surface. The shank is made for fixing in the cartridge of a surgical electric drill (patent RU No. 2289332, АВВ 17/32, 12/20/2006).

The disadvantage of this device is the difficulty of dosing the thickness of the removed devitalized tissues.

A device for treating wounds is known, which is a wound dressing that comes into contact with the wound surface. The coating for covering the wound surface and the wound dressing is a sealing film (patent RU No. 2389457, A61F 13, 05.20.2019).

The disadvantage of this device is the inconvenience of use in the abdominal cavity.

A device in the form of a napkin for cleaning, surgical treatment of wounds or skin is known. The napkin contains at least one carrier layer, filaments located on it and protruding from it, preferably made exclusively of synthetic fibers, preferably polymer fibers. At least some threads, preferably at least 50%, on their side opposite to the carrier layer have freely protruding cut ends extending at an angle to the direction of their longitudinal extent. The napkin is used complete with packaging (patent RU No. 2524874, A61F 13/00, 08/10/2014).

The disadvantage of this device is the unreliability of composite materials.

A device for treating chronic wounds is known, including a device for cleaning the wound, a reservoir with an extracellular polymer substance solvation system and an aspiration device (patent RU No. 2513142, А61М 3/02, 20.046.2014).

The disadvantage of this device is its bulkiness.

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 work surface. EFFECT: more reliable retention of a tissue layer during excision (patent RU No. 2330624, АВВ 17/28, 08/10/2008).

The disadvantage is the inconvenience of use in small wounds.

The objective of the utility model is to stimulate the healing processes of non-healing wounds and trophic ulcers.

The technical result of the utility model is to increase the efficiency of surgical intervention by stimulating the healing processes of non-healing wounds and trophic ulcers due to reliable and complete cleaning of the wound surface.

The technical result is achieved in that a device for treating a wound surface containing two intersecting branches connected by a hinge axis, at one end of which there are rings for fingers and a cremalier retainer, and at the other end are working parts that are made in the form of clamps having the shape of half rings, on the inner working part of which small teeth are made for tight fixation of the bilateral sponge at the border of the transition of the soft part to the hard one, without deformation of the latter.

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 initial position; in FIG. 2 shows a disclosed model of the device, front view; in FIG. 3 shows a double-sided sponge; in FIG. 4 shows an assembly model of the device, front view in the working position; in FIG. 5 shows a cross section of the working part with a sponge in a lateral projection.

The device for processing the wound surface has two intersecting branches 1, interconnected by a hinge 2. At one end of the branch there are rings for the fingers 3, and a cremallera retainer 4, and at the other end there are working parts 5, which are made in the form of half rings. Small teeth 6 are made on the inner side of the working part. This allows tightly holding the double-sided sponge 7 in its middle part without excessive deformation of the material and cleaning in full.

A device for processing a wound surface works as follows (Fig. 4). Pre-produce necrectomy of the wound in a blunt and acute way. Then, for better processing and stimulation of the reparative process using a tampon holder. The working parts 5 of the device are fixed on a double-sided sponge 7 at the border of the transition of the soft part into the hard part with the help of a cremallera clamp 4. After cleaning the wound, the device is removed.

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 working conditions of the surgeon, which, in turn, improves the quality and accelerates the course of surgery.

A device for the treatment of wound surfaces 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 using the proposed device for processing the wound surface. 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 the obligatory treatment of the wound surface with the working element of the tampon holder. Wound healing by secondary intention. Discharged for outpatient treatment at the clinic at the place of residence 05.12.18. Examined by a surgeon at the outpatient clinic SOKB im. V.D. Seredavina 01/11/19 - satisfactory general condition, wound healing by secondary intention, no relapse.
