Abstract

FIELD: medicine; plastic surgery.

SUBSTANCE: invention used at cosmetic operations performance. The surgical suture is executed from a metal, polymeric or biological material. The suture has elements of bracing of hypodermic tissues. The suture has the helicoid form. The suture is executed in the form of a compression or stretching spring. Diameter of a spiral makes 0.5 mm to 5 mm. Diameter of a suture makes 0.1 mm to 1 mm. A helicoid form suture in the form of a compression or stretching spring is fixed by the forward end to the pointed end of an aspirating needle. The suture is densely coiled on a needle or is fixed in an aspirating needle gap. A needle and a suture are entered into a hypodermic fat along the selected contour. If there is a stretching spring a needle with a suture are entered in the stretched condition. If there is a compression spring a needle with a suture are entered in the compressed condition. A suture is leaved subcutaneously in a strained state with aspiration to be constricted or be stretched under the influence of spring properties. Thus the suture, according to a condition compresses a subcutaneously-fatty fat with creation of effect of a tightening of ptotic tissues. At putting a needle in it is rotated on a course of coiling of suture coils. At putting a needle out it is rotated in an opposite direction. In that specific case a suture is fixed in a gap of an aspirating needle with a backlash between diameter of a spiral and an internal wall of a needle from 0.2 to 2 mm. Two sutures are put in parallel in that specific case. Sutures ends are pulled towards each other and among themselves. Sutures ends are put under the skin and the uniform structure tightening of ptotic tissues is created. The offered method and device allow out-patient under local anaesthesia to carry out minimally invasive, simple, bloodless interventions without formation of cicatrixes with the short rehabilitation period. Thus operation can be applied as separately, and in a combination with other surgical interventions at cosmetic operations. The method and the suture allow to tight in regular intervals of soft tissues upwards, to receive proof effect of sentinel piles and rhytides effacement, effect of a rejuvenation of the growing old face, remaining at mimic movements, at face skin massage, at nutrition chewing process.

EFFECT: reception of proof effect of sentinel piles and rhytides effacement at mimic movement preservation.

Description

The invention relates to medicine, to materials and methods for performing aesthetic operations. In particular, it relates to medical materials used in plastic surgery for cosmetic surgery.

State of the art

Surgical threads for cosmetic operations are known, they are made of various materials: metal, polymer, biological. General characteristics of the threads: strength, smooth surface, bioinertness. Recently, filaments with microscopic protrusions at an angle have been proposed and used, which allow the filaments to pass through the tissues in only one direction.

Depending on the nature of the operation, various surgical sutures are used. These are threads from wires: tantalum, gold, nickel and others. Non-metallic threads are used from lavsan, nylon, kapron, polypropylene, vicryl, polysorb and other materials.

Correction of facial wrinkles with a decrease and loss of skin elasticity, ptosis (sagging) of soft tissues remains one of the main problems of cosmetic surgery. For this purpose, surgical sutures without protrusions are used in aesthetic surgery only for surgical suturing in an open wound. Thus, it is possible to tighten and hem the lowered soft tissues only after appropriate incisions and mobilization of skin-fat flaps.

Filaments with protrusions allow you to tighten and fix soft tissue without surgical incisions. Methods for setting such threads through skin punctures using special needles have been developed and used. Such manipulations allow you to get a pretty good lift of the soft tissues of the lateral areas of the eyebrows, cheekbones, mental and submental areas, create good aesthetic contours of these parts of the face. This is achieved by the fact that in these areas of the face the effect of facial and chewing muscles is not very pronounced, the protrusions are not exposed to them and the fixation of tightened tissues is stable. At the same time, such threads, placed in places where muscle activation is expressed, do not lead to long-term, stable results: in the next 10-14 days after their setting a relapse occurs - prolapse of soft tissues, since the natural action of the muscles leads to weakening of the protrusions and even their separation. It:

- the frontal region, for raising the eyebrows and the nose, and with them the skin of the upper eyelids;

- the angle of the mouth, for raising the soft tissues of the near-mouth areas and eliminating wrinkles of “sadness”;

- cheeks, for raising the soft tissues of these areas;

- neck, for tightening the skin of the neck, for smoothing wrinkles of the skin of the neck.

The closest to the merits of the claimed invention are surgical threads for cosmetic operations WO 03/103733. These threads are made with nicks on their surface, while the implementation of these nicks is subordinate to the purpose of using these threads.

Disclosure of invention

The problem is solved in that the thread for cosmetic operations, made of metal, polymer or biological material with elements of fixation of subcutaneous tissue, is made in a spiral shape in the form of a compression or tension spring with an outer diameter of the spiral from 0.5 to 5 mm, and the diameter of the thread material from 0.1 to 1 mm, which provides a good result of tissue tightening with the application of a slight operating injury. A method is also proposed for performing a cosmetic operation using a surgical thread, which consists of introducing it into the subcutaneous tissue for the purpose of tightening and fixing them and characterized in that the spiral-shaped thread in the form of a compression or tension spring is attached with its front end to the sharp end of the puncture needle and the thread is tightly wound the needle or the specified thread is strengthened in the lumen of the puncture needle, then the needle with the thread is inserted in the stretched state along the needle length with the tension spring or in the compressed state with the compression spring in the cellulose along the intended contour, and after the needle is punctured, the thread is unfastened, the needle is pulled out, and the thread is left subcutaneously in a tense position with a tendency to compress or stretch under the influence of spring properties, while compressing subcutaneous fat in accordance with the condition, creating the effect of tightening ptosis tissue moreover, when the needle is inserted, it is rotated along the winding of the threads, and when it is withdrawn, it is rotated in the opposite direction.

Fastening the thread in the lumen of the puncture needle can be carried out with a gap between the diameter of the spiral and the inner wall of the needle of the order of 0.2 mm to 2.0 mm.

By the nature of the operation, subcutaneous tissue can be fixed over the intended area. For this purpose, two parallel threads are introduced, then their ends are drawn towards each other, connected together, sunk under the skin (by massaging the skin with your fingers) and create a single structure that tightens the ptosis tissue.

The implementation of the invention

Surgical thread 1 spiral shape is made of metal, polymer or biological material. Depending on the nature of the cosmetic operation, the threads are used in various sizes. The diameter 2 of the spiral can be from 0.5 to 5 mm, and the diameter of the material 3 threads from 0.1 mm to 1 mm. The nature of the operation is dictated by the use of threads from the appropriate materials. Surgical threads - spirals are made with the properties of compression or tension springs. The spring properties of the threads are given by methods of thermal action on them, which differ depending on the material of the thread.

A variety of cosmetic surgeries and their place of execution in patients also require different ways of performing them. A spiral-shaped thread is inserted into the subcutaneous soft tissue using a puncture needle 4. A thread is wound onto a thin needle from the outside so that each turn 5 is snug against adjacent turns. The front end 6 of the thread is fastened to the sharp end of the 7 needles. When introducing a spiral with the properties of a tension spring, it is stretched along the needle 8 long by 2-3 times and the second end 9 of the thread is strengthened to the other end 10 of the puncture needle 4. If the spiral is loosened, it becomes short.

In the extended state, the filament-helix is injected subcutaneously into the soft tissues as follows.

The needle is pierced with a needle and the needle is pulled subcutaneously along a predetermined contour, moreover, it is inserted in a spiral like a gimlet, rotating along the winding 5 of the threads. In the right place, the needle 4 is punctured on the surface of the skin 11 and the end of the thread 9 is held with tweezers or a clamp. Then, with cautious spiral movements, but in the opposite direction with respect to the introduction of the needle, it is withdrawn from the subcutaneous tissue, and the thread-spring 1 remains subcutaneously in a stressed state, that is, in an effort to compress under the influence of spring properties. According to the condition of the thread, subcutaneous fat is compressed, thus creating the effect of tightening ptosis tissues.

Another method of operation is characterized in that the spiral thread 1 is placed in the lumen 12 of the puncture needle 4 with a gap 13 between the diameter of the spiral and the inner wall of the needle of the order of 0.2 mm to 2 mm and a needle with a thread is inserted into the subcutaneous tissue. In the described methods of application, the thread-spiral can be with the properties of a compression and tension spring. When using a filament-helix with the properties of a compression spring, it is squeezed when inserted subcutaneously into soft tissues, and after removing the needle, the filament-helix with a tendency to unclench remains in the subcutaneous soft tissues.

Another example of the application of the method is that two spiral filaments 14, 15 are introduced subcutaneously in parallel, then their ends 16, 17 are subcutaneously led towards each other, connected 18, 19 and form a single structure that tightens ptosis tissues. This manipulation allows you to evenly pull the soft tissue up and thereby achieve the effect of smoothing wrinkles and skin folds. In this case, facial movements of the skin of the face, the process of chewing food, and even massage the skin do not lead to a loss of the achieved effect, since together with stretching and squeezing the skin, the spring threads in the subcutaneous tissue are stretched and compressed, maintaining their previous shape. Subsequently, these threads are covered with fibrous tissue, which helps to stabilize the effect. Several such threads, performed subcutaneously in the necessary areas of an aging face, create a rejuvenating effect.

Industrial applicability

As shown in the description, the present invention can be widely used in various cosmetic and plastic surgeries, both independently and in combination with other surgical interventions.

When using spiral-shaped filaments, in many cases there is no need to carry out heavy surgical operations such as ritidoplasty. Manipulations with the use of such threads are simple and bloodless, they do not leave scars, they are performed on an outpatient basis under local anesthesia and a short rehabilitation period. They can be combined with the setting of threads with notches and other minimally invasive procedures and procedures that are used in cosmetic surgery.
