Abstract

Children's gynecological spatula, consisting of a handle and a working part with villi for collecting biological material, and an atraumatic polymer ball at the free end, characterized in that the working part has a conical shape from 10 to 20 mm in length, from 2 to 3 mm in diameter; on the surface of the working part at a 90 ° angle to it, villi are staggered from 1 to 2 mm high; the working part in the area of connection with the handle has an external thread; the handle is a hollow cylinder with a length of 100 to 170 mm, having an internal thread for connecting to the working part; below the connection with the working part, the handle is bent at an angle of 140 °.

Description

The utility model relates to medical equipment, namely to disposable medical children's gynecological instruments for collecting biological material from the surface of the vaginal mucosa for bacteriological and cytological studies.

Known medical spatula for collecting biological material, made of plastic. It contains a handle, at the opposite ends of which there are working surfaces with external edges. Through holes are made through the outer edges of the working surfaces. The holes are separated by jumpers. The lateral surfaces of the holes form the inner working edges [1].

The disadvantage of a spatula is that it has a small surface for collecting biological material; is a reusable spatula that requires treatment with an expensive disinfectant solution, washing and boiling.

Known combination sampling tool, which contains an elongated handle and two shanks. At the remote ends, one working body was taken for sampling. The shanks are directed with their remote ends along the longitudinal axis of the handle to the opposite sides of it and have a width of no more than the width of the handle. One working body is made in the form of a spoon, the width of which is not less than the width of the end of the shank at the place of its connection with the spoon. The second working body is made in the form of a flat spatula with a width that is greater than the width of the handle. The length of the handle is not more than half the distance between the remote ends of the shanks and not more than the length of the shank, at the end of which a spoon is made [2].

The disadvantages of the tool is that it has a handle of complex shape, time-consuming to manufacture and use.

Known urogenital probe having a handle and a working part in the form of a brush with a spiral arrangement of villi, the free end of the working part is equipped with a polymer ball to ensure atraumatic probe [3].

The disadvantages of the tool is that its design is not suitable for the collection of biological material from the walls of the vagina in virgo girls. This tool is taken by us as a prototype.

The purpose of creating a utility model is to develop a gynecological spatula that takes into account the anatomical features of the genitals in virgo children of different ages.

This goal is achieved in that the working part of the spatula has the shape of a cone with a length of 10 to 20 mm, a diameter of 2 to 3 mm; on the surface of the working part at a 90 ° angle to it, villi are staggered from 1 to 2 mm high; the working part in the area of connection with the handle has an external thread; the handle is a hollow cylinder with a length of 100 to 170 mm, having an internal thread for connecting to the working part; below the connection with the working part, the handle is bent at an angle of 140 °.

In childhood, the genitals have their anatomical features in different periods. So with age, the shape, length and position of the vagina changes. Therefore, varying the length of the working part and the length of the handle of the spatula allows the doctor to choose the required length of the working part and or the handle of the instrument, depending on the anatomical features of the baby's vagina. At an acute angle to the vertical axis of the pelvis, the vagina begins to be established only closer to eight years. Therefore, the connection of the working part of the spatula with the handle, which is bent at an angle of 140 ° allows anatomically and slightly traumatic sampling of biological material, penetrate the spatula beyond the hymen and take biological material directly from the walls of the vagina. In most cases, girls take material only from the vaginal lumen or from the external genital organs, which does not ensure the completeness of the diagnostic picture. The proposed children's spatula is simple and convenient for the doctor.

The technical result of the use of a spatula is to ensure anatomical collection of biological material from the walls of the vagina in virgo children of different ages.

A pediatric gynecological spatula consists of a working part and a handle, and the working part of the spatula has a cone shape from 10 to 20 mm long, 2 to 3 mm in diameter with an atraumatic polymer ball on top; on the surface of the working part at a 90 ° angle to it, villi are staggered from 1 to 2 mm high; the working part in the area of connection with the handle has an external thread; the handle is a hollow cylinder with a length of 100 to 170 mm, having an internal thread for connecting to the working part; below the connection with the working part, the handle is bent at an angle of 140 °.

The tool is illustrated with graphic material. The figure 1 shows a pediatric gynecological spatula consisting of a working part 1 having the shape of a cone and a handle 2. At the top of the working part 1 there is an atraumatic polymer ball 3. On the surface of the working part 1, villi 4 are staggered at a 90 ° angle to it. The working part 1 in the area of connection with the handle 2 has an external thread 5. The handle 2 is a hollow cylinder having an internal thread 6. For connecting to the working part 1, the handle 2 is bent at an angle 7 of 140 °.

Children's gynecological spatula is used as follows.

Depending on the age of the child virgo and, accordingly, the anatomical features of the vagina, the gynecologist selects the handle and the working part of the spatula of certain lengths and fastens them through a threaded connection. Getting a spatula for hymen, carries out the collection of biological material directly from the walls of the vagina due to the presence on the surface of the working part of the villi from 1 to 2 mm high, staggered to it at an angle of 90 °. The working part with the biological material collected on it is disconnected from the pen and sent to a diagnostic study. It is possible to use a hollow cylindrical handle of the tool as a container for transporting the working part with biomaterial to the laboratory.

A pediatric gynecological spatula can be recommended for collecting biological material from the walls of the vagina in virgo children of different ages in gynecological hospitals.
