Description

The utility model relates to medicine, namely to the field of experimental pharmacology and is intended for the implementation of models related to the formation of a skin flap on the “leg” in laboratory animals.

A flap in surgery is a tissue site that has a significant area with a relatively small thickness, separated from the body, for example, by surgery (http: //www.medkmg.rn/vocabulary/show/96562; Encyclopedic dictionary of medical terms).

When implementing some pharmacological models in laboratory animals, a skin flap is also formed, incl. skin flap on the “leg” (http://www.rntv.ru/tvpreg.hnnl?id=108702&d=; Protasov MV et al. Possibility of predicting epithelialization of wounds in rats by changing the activity of matrix metalloproteinases in wound exudate / Cytology . -2009. - T.51, No. 4. - S. 311-314.).

To create a skin flap using knives of various designs - dermatomes. For the purposes of plastic surgery, dermatomas of various designs are used to remove a skin flap (http://www.dermatom.ru/select/select.htm; Patent RU No. 94839, publ. 06/10/2010; Patent RU No. 56802, publ. 09/27/2006 ; Certificate RU No. 553, published on July 16, 1995). There are two most common types of dermis toms - reciprocating and disk.

A high-tech medical tool with improved characteristics is proposed - dermatome.

It is intended for cutting and perforation of skin grafts during plastic surgery, as well as for cutting necrotic tissue (http: //www.sciinnov.rn/icatalog_new/entry_81641.htm).

There is a device for modeling the wound surface of a given size in laboratory animals (RU No. 79701, publ. 10.01.2009), which includes a handle and a rubber pad, as well as four metal rods with pointed ends for fixing the device on the skin without displacement.

The disadvantage of these devices is their unsuitability for the formation of a skin flap on the "leg" in laboratory animals.

The objective of this utility model is to create a device for forming a skin flap on the "leg" in laboratory animals.

The problem is solved by creating a device for the formation of a skin flap on the "leg" in laboratory animals, which has a handle and a base, the base having a U-shaped end knife with a gear sharpening around the perimeter.

Distinctive features of the proposed technical solution is that the device has a U-shaped end knife, which allows you to form a skin flap on the "leg" of laboratory animals, and the serrated knife sharpening allows you to tightly fix the device on the skin of the animal without displacement.

Comparison of the proposed device with others known in the field of experimental medicine, showed its compliance with the criteria of a utility model.

The utility model is represented by graphic material, in which figure 1 shows the proposed device for the formation of a skin flap on the "leg" in laboratory animals.

The device contains a base 1, a handle 2, an end knife 3. The parameters of the proposed device depend on the size of the used laboratory animals and the requirements of the experiment.

The device operates as follows.

The device is applied to the skin of the experimental animal with the base 1, holding it by the handle 2, after applying the device to the skin, it is tightly fixed by the end knife 3. Using a scalpel, the lines bounded by the U-shaped end knife are drawn around. In this case, the fourth side of the flap is not injured, but is saved as a “leg”. After removing the device from the skin of the experimental animal, the flap is cut from the side of the slots, and remains to hang on the not cut side of the flap - on the "leg".

Thus, the proposed device, it is possible to form a skin flap on the "leg" in laboratory animals, ensuring its standard size, avoiding unnecessary injury to laboratory animals.

The proposed device for modeling a skin flap on a “leg” in laboratory animals can and should be used to solve problems of experimental pharmacology, including in preclinical studies.
