Abstract

The utility model relates to the field of medicine and veterinary medicine, namely to experimental pharmacology, and refers to a group of devices used to implement pharmacological models associated with the formation of a skin flap on a pedicle in laboratory animals. The device includes a handle and a base with a U-shaped end knife with serrated sharpening, placed in a protective casing, fixed on the working part of the base by a compression spring. With a short press on the handle, the protective cover moves up along the base along with the spring, while the knife forms a skin incision that is even in depth. Using the device, it is possible to form a uniformly cut skin flap on a feeding leg of a standard size in laboratory animals.

Description

The utility model relates to the field of medicine and veterinary medicine, namely to experimental pharmacology, and refers to a group of devices used to implement pharmacological models associated with the formation of a skin flap on a pedicle in laboratory animals.

An electrosurgical dermatome is known (Patent RU No. 94839, publ. 06/10/2010), consisting of a ceramic blade with a monopolar electrode, containing a contact for supplying electric current on the handle, and a ceramic cutting blade with a metal-dielectric composite structure at the distal end.

Known dermatome (Patent RU No. 56802, publ. 09/27/2006), containing a handle and a working part with a cutting edge, characterized in that the working part is made in the form of a U-shaped gutter with an angle of inclination of the bottom of the gutter at an angle of 5-10 ° to longitudinal axis, and a millimeter scale is made at the bottom of the gutter.

Known as a dermatome (Certificate RU No. 553, publ. 07/16/1995), containing a body with a glass, a removable rotary cover and a mechanism for fixing the cover from axial movement relative to the glass, a cutting unit with a movable knife, a drive for moving the knife with an electric motor and a mechanism for fixing the electric motor in housing, a power input unit having a cable and a connector, and an on-off mechanism, characterized in that the cover fixing mechanism in it is made in the form of a cylindrical split spring hollow crown latch placed in the inner cavity of the cover, fixedly fixed on the motor housing in such a way that its "crown" with cuts is directed in the direction opposite to the electric motor, and on the open side of the "crown" on its outer surface, protrusions are made at the edge, placed in an annular groove on the wall of the inner cavity of the cover.

Known high-tech medical tool with improved characteristics - dermatome (http://www.sciinnov.rn/icatalog_new/entry_81641.htm), designed for cutting and perforating skin grafts during skin plastic surgery, as well as for cutting necrotic tissue.

A device for modeling a wound surface of a given size in laboratory animals (RU No. 79701, publ. 01/10/2009) is known, 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.

A device for forming a skin flap on a "leg" in laboratory animals is known, which has a U-shaped end knife with serrated sharpening (RU No. 110524, publ. 20.11.2011).

All of the above devices are unsuitable for the formation of a skin flap on the feeding leg in laboratory animals and for ensuring uniform penetration of the knife along the entire perimeter of its sharpening.

The technical problem solved by the proposed device is to expand the arsenal of technical means for the formation of a skin flap on a feeding leg in laboratory animals, ensuring uniform penetration of the knife along the entire perimeter of its sharpening.

The technical result consists in the implementation of this purpose.

To achieve a technical result, a device for forming a skin flap on a pedicle in laboratory animals consists of a handle, a base with a U-shaped end knife with serrated sharpening, a movable protective casing fixed on the working part of the base by a compression spring.

The utility model is illustrated by a drawing showing the proposed device for forming a skin flap on a pedicle in laboratory animals. The positions in the drawing indicate:

1 - handle,

2 - base,

3 - U-shaped end knife with serrated sharpening,

4 - movable protective cover,

5 - compression spring.

The device works as follows

The base 2 of the device is installed with a protective cover 4 in the area of the flap formation on the feeding leg. With a short press on the handle 1 of the base 2, the protective cover 4 moves together with the spring 5 up the base 2, while the knife 3 forms a skin incision uniform in depth. After removing the device from the skin of the experimental animal, the flap is trimmed from the side of the slots, and remains hanging on the non-cut side of the flap - on the feeding leg.

Due to the proposed design of the device, uniform penetration of the knife of the device for the formation of a skin flap on a feeding leg of a standard size in laboratory animals is achieved along the entire perimeter of the knife sharpening.

Thus, the technical result is achieved.

Claims (1)

A device for forming a skin flap on a feeding leg in laboratory animals, comprising a handle, a base with a U-shaped butt knife with serrated sharpening, characterized in that a movable protective casing is installed on the working part of the base, fixed with a compression spring.
