The technical field

The invention relates to medicine and techniques and methods of performing surgical and plastic surgery. In particular, the invention relates to implants used in reconstructive plastic and aesthetic operations.

Prior art

Implants for reconstructive, plastic and aesthetic surgery known (Azatan "reconstruction of the female breast". Publishing House Of Academy Of Sciences Of Hungary. 1989 Nimalendran "Clinical operative oral and maxillofacial surgery", "Medicine", Moscow, 1985, pp. 94-95). Known implants are made of various polymeric and biological materials and contain shell, General characteristics - strength, mesh, smooth, smooth or textured surface, density, bioinert. After implantation in the region of the defect implants to replace the defect, to eliminate contour deformation and long hold postoperative outcome. All known mesh implants are usually carefully filed to the edges of the defect and only after that they perform a support function. Apply mesh implants and cosmetic breast surgery. Also used implants with a textured surface of the shell, the nab, the emer prostheses for augmentation mammoplasty company McGan.

Germination of recesses on the surface of such prostheses connective tissue does not give stable fixing them in the long term. Over time, the gravitational forces lead to slipping dentures down, sagging Breasts and poor aesthetic results.

Similarly worsen postoperative aesthetic results and after rhinoplasty, when over time the tip of the nose is sliding with silicone implant and hanging over the lip.

Closest to the claimed technical solution is the endoprosthesis, the shell of which is made with a textured surface. Textured surface contains irregularities between threads, which germinate connective tissue. But this is not enough for long-lasting and durable retention of the implant in the soft tissues.

We propose a new surface of the endoprosthesis, which allows you to capture not only the implant without the usual filing of the soft tissues, but also soft tissue.

Disclosure of inventions

The problem is solved in that the implant for reconstructive, plastic and aesthetic surgery of the bioinert polymer material contains a shell, the surface of which is made with protrusions in the form of inclined conical pointed ends himcourage C is Osintsev, in this orientation, location, and spacing between the burrs are made different depending on the purpose of the endoprosthesis, and the excess ends of the protrusions above the surface respectively, the appointment is from 0.01 to 5 mm

The present of the invention is a surgical implant, the shell of which is firmly fixed in the body and keeps the denture yourself soft tissue from movements that are generated by the movements of the body and the gravitational effects on the body.

The problem is solved by the specified running the shell of the endoprosthesis.

It is advisable that the tabs-burrs tape endoprosthesis was performed on one side of the tape or on its two sides with one orientation and staggered.

It is also advisable that the tabs-burrs were made on both sides and had an opposite direction from the middle of the endoprosthesis continuous form.

It is also possible alternation of the direction of the ledges-burrs through each row.

Implants of three-dimensional form can be different ways of applying tabs-Burr:

- one-way one-way ledges-Burr

also the alternation of the direction of inclination of the projections of burrs on each of the hundred who he is.

Brief description of drawings

Further, the invention is illustrated with specific examples of its implementation and the accompanying drawings, on which:

The main variant of carrying out the invention

The endoprosthesis 1 for p is constructive and reconstructive plastic surgery ribbon-like shape with the shell 2, surface 3 which is made with the protrusions 4 in the form of inclined conical pointed ends 5 himcourage burrs 6. Interval 7 between the burrs 6 is different, depending on the purpose of the endoprosthesis. Exceeding 8 all 5 of burrs 6 respectively the appointment of the endoprosthesis can be made different from 0.01 to 5 mm

In figure 1,2,3,4 shows the different implementation of the protrusions of burrs on the surface of the shell of the endoprosthesis: unidirectional on one side and on two sides of the tape respectively, in opposite directions from the middle belt of the implant (figure 5 and 6).

7 and 8, the tape endoprosthesis with alternating orientation of the projections of burrs through each row on both sides. It is preferable to arrange the tabs in a checkerboard pattern with the aim of preserving and increasing the strength of the shell of the endoprosthesis and the best fixing it to the soft tissues.

Figure 9 shows the volume endoprosthesis 9, the surface of which is made tabs-burrs 6-sided orientation on one side of the shell 10.

Figure 10 shows the volume implant with alternating tilt tabs-Burr 6 on each side.

Surgery to eliminate sagging of soft tissues of neck as follows. With wire scalpel is made of undercutting dermal-fat flap on the target markup and thus creating a subcutaneous tunnel in the neck, then in the ear areas on both sides are made slits in the skin about 1.5-2 see Through these incisions on the created tunnel stretched mesh belt implant (figure 5), then he pulls up on both sides with the necessary force and is pressed to the soft tissues. This ledge-burrs 6 on the ribbon cling to the wound surface and the skin side and platysma, locking the tape in position, thereby eliminating the sagging neck. Then sutured wound. Figure 11 schematically illustrates a surgical correction of the nose 13, implant 14, the skin and subcutaneous tissue 15.

Industrial applicability

As shown, the invention can be used in various reconstructive, aesthetic and plastic surgery.
