Description

The field of technology.

The utility model relates to medical prostheses and can be used to compensate for tissue deficiency in the area of the removed nipple-areolar complex (hereinafter - SAK) in patients who underwent surgery on the mammary gland.

Often, women who have had breast surgery experience depression, which is a problem for many patients. Depression can make it difficult for a patient to recover from surgery and increase fatigue after chemotherapy and radiation. It may take time for patients to get used to breast loss. For psycho-emotional recovery and cosmetic appearance, patients can use exoprostheses of SAH.

The level of technology.

There are a large number of exoprostheses of NAO made outside the Russian Federation, in particular in China, Korea and Taiwan, which do not always correspond to the anatomical appearance, the lack of variety of models and the short fixation period and not officially registered in the Russian Federation. Delivery of this product to patients is carried out by mail and has a high cost (about 280 y.e.).

Known exoprosthesis of the company MedProm (International Quality Certificate TUV NI 60014004. 02.27.2006).

However, the known exoprosthesis does not correspond to the natural appearance and has a short fixation period.

The closest analogue is the Silima® self-adhesive nipple prosthesis, which is made of self-adhesive silicone and can be fixed both on the silicone exoprosthesis and on the skin (http://www.silima.su/catalog/exo/soski.php).

The disadvantages of this exoprosthesis are: an unnatural appearance that does not correspond to the anatomical appearance of the nipple, a short fixation period, and the lack of variety of models.

The essence of the technical solution.

The technical problem to which the utility model is directed is to improve the quality of life of patients who underwent breast surgery, reduce the cost of the exoprosthesis, improve its appearance, taking into account the individual approach to each patient.

The technical result consists in the creation of an individual exoprosthesis of the nipple-areolar complex, which imitates the nipple-areolar complex (SAC) and is waterproof.

The technical result is achieved by the fact that the exoprosthesis of the NAO is made according to an individual impression of a two-component soft silicone on a platinum basis, and the areola is made translucent. For staining NAO use dye for silicone makeup.

The utility model is illustrated by graphic materials:

FIG. 1 - cast of the nipple-areolar complex of alginate powder.

FIG. 2 - filling the nipple with two-component soft silicone on a platinum basis.

FIG. 3 - a) coloring the nipple in tone using special dyes; b) filling the areola and staining to the desired tone.

FIG. 4 - a) separation of the silicone form from the alginate cast; b) the type of finished exoprosthesis: 1 - an exoprosthesis of NAO, 2 - a nipple, 3 - an areola, 4 - Montgomery tubercles.

FIG. 10 is a view of patient P., after attachment of an exoprosthesis of SAH.

The essence of the utility model is not limited to the description below.

Implementation of a utility model.

Before or after the operation to remove the mammary gland, the patient is made an NAP cast and a color tone is selected for the manufacture of an exoprosthesis. When making an impression, medical alginate powder is used to take impressions (for example, Phase Plus Zhermack clinical, production: Italy). After the mold has completely dried (Fig. 1), a two-component, soft platinum-based silicone is gradually poured into the mold cavity, at the first stage, the nipple cavity is poured (Fig. 2), stained in the required tone with a special dye for silicone makeup (for example, Smooth -On Silc Pig) (Fig. 3a). Next, the areola is filled and stained in the required tone with the above dyes (Fig. 3b). The cast mold forms dry at room temperature for 30 minutes. The finished CAA exoprosthesis is separated from the alginate cast (Fig. 4a). The finished exoprosthesis (Fig. 4b) completely imitates the nipple-areolar complex 1, the nipple 2, and the areola 3 with Montgomery 4 tubercles.

Use of utility model.

Example 1. Patient I., 41 years old (Fig. 5). Operation performed: Subcutaneous mastectomy.

Before a mastectomy, the patient was made a cast of NAO and selected a color tone for the manufacture of an exoprosthesis. When performing the impression, medical alginate powder was used to take impressions (Phase Plus Zhermack clinical, made in Italy). After complete drying, the mold cavity was filled in two stages using two-component soft platinum-based silicone for makeup Smooth-On Ecoflex 00-30. The first step was the filling of the nipple (Fig. 2), stained in the selected tone using dyes for silicone makeup Smooth-On Silc Pig (Fig. 3a). The second stage was the filling of the areola and stained (Fig. 3b). At the request of the patient, the areal of the nipple was made smaller. The poured form was left to dry at room temperature for 30 minutes. After drying, the silicone form (exoprosthesis SAK) was separated from the alginate cast (Fig. 4a). Exoprosthesis 1 (Fig. 4b) fully corresponds to the removed NAO and completely imitates the nipple 2, areola 3, and Mantgomery 4 tubercles.

Two months after surgery, the patient came to the reception (Fig. 6). After examination, an exoprosthesis of SAH (Fig. 4b) was attached to the skin. To do this, latex was coated on the attachment side of the exoprosthesis and fixed to the skin with silicone glue for long-term mobile makeup Smooth-On Skin Tite (Fig. 7). The patient was given recommendations on the use of an exoprosthesis of SAH.

The long-term result three months after using the exoprosthesis of NAO: the patient is satisfied, leads an active lifestyle (swims, sunbathes), does not experience inconvenience in intimate life.

Example 2

Patient P., 47 years old (Fig. 8). The patient underwent surgery: Subcutaneous mastectomy (Fig. 9).

Before the operation, a cast was made. An exogenous prosthesis was prepared according to the above procedure. After complete drying, the exoprosthesis SAK was attached to the skin using latex and silicone glue for long-term mobile makeup Smooth-On Skin Tite (Fig. 10).

The long-term result 2.5 months after using the exoprosthesis of NAO: the patient is completely satisfied, socially adapted, leads an active lifestyle.

Industrial applicability - the NAO exoprosthesis has a simple design, is not complicated to manufacture, does not require sophisticated technological equipment, and can be used in oncological institutions, where the removal of NAO is most often performed in patients with breast cancer. An exoprosthesis is more cost-effective than its counterparts and avoids difficulties in ordering such products in foreign companies. Due to the tight fit to the skin, you can lead an active lifestyle. In addition, in case of loss, an exoprosthesis can always be made according to the finished cast for 40-30 minutes, even at home.
