Description

The invention relates to materials for face and body soft tissue tightening and can be used in medicine, in particular plastic surgery, surgery, cosmetology, dermatovenereology, gynecology.

Surgical materials for soft tissue tightening are widely known, which use a combination of rigid and elastic threads that provide additional tension due to elastic deformation of elastic threads described in the documents: CH)); - US 11045299 B2 "Implant for tissue lifting" published 06/29/2021 (Patent holder: Kim Jong Woo (KR)); - KR 100745571 B1 "Linear tension material for plastic surgery" (03.08.2007) (Patent holders: Lee Jung II (KR) and Han Kwang Nee (KR)); - RU 2323689 C2 "Sheathed elastic surgical thread" (05/10/2008) (Patent holder: Capurro Sergio (IT)); - WO 2009112683 A2 "Surgical thread for reconstruction in the field of cosmetic surgery and medicine" (09/17/2009) (Applicants: 1st Surgiconcept (FR); Frismand Jean (FR)).

Common disadvantages of the known designs are the complexity of making and manufacturing threads, as well as the high probability of inflammation of the soft tissues due to the high value of the fecundity of the threads from these documents compared, for example, with polypropylene threads, as well as the unreliability of attachment to soft tissues at the attachment point.

The invention is directed to the creation of a surgical thread for tissue tightening, which would solve the mentioned disadvantages identified in the prior art.

The technical result of the invention is to create a safe in terms of tissue inflammation and fastening of a surgical thread for tissue tightening, with a simple design and manufacture.

The technical result is achieved due to a set of essential features, in which the surgical thread for tissue tightening consists of threads with locking elements connected to a shock-absorbing element, while the threads with locking elements have a lower linear density than the shock-absorbing element, while the threads with locking elements and shock-absorbing element is made of non-biodegradable material, wherein the shock-absorbing element is made with the possibility of attachment to tissues, while the threads with locking elements are made with the possibility of connection with a surgical needle, while the first thread with locking elements is connected to the shock-absorbing element on one side, and the second and the third thread with locking elements are connected on the opposite side of the damping element.

In particular cases, threads with locking elements are made of polypropylene. In additional embodiments, the locking elements of the threads are oriented in the opposite direction when the threads are tensioned with the locking elements. In additional embodiments, the shock-absorbing element is made of silicone. In additional embodiments, the shock-absorbing element is made in the form of a ring. In yet another embodiment, threads with locking elements are connected to the shock-absorbing element at opposite ends of its diameter. In yet another embodiment, the arc angle of the circular segment defined by the connection points of the second and third threads with the locking elements with the damping element is sharp, straight or blunt. In another embodiment, the damping element is made in the form of a U-shaped insert, and threads with locking elements are connected to the ends of the damping element.

The essence of the invention is illustrated by figures 1-10.

Surgical thread for tissue tightening (Fig. 1-10) consists of threads (1) with locking elements (3) connected to a shock-absorbing element (2). Threads (1) with locking elements (3) have a lower linear density than the damping element (2). Threads (1) with locking elements (3) and damping element (2) are made of non-biodegradable material. The damping element (2) is made with the possibility of attachment to the tissues (Fig. 4, 5). Threads (1) with locking elements (3) are made with the possibility of connection with surgical needles (4).

The stop elements (3) of the threads (1) can be oriented in the opposite direction of the tension of the threads (1) with the stop elements (3). The shock-absorbing element (2) can be made in the form of a ring, and threads (1) with locking elements (3) can be connected to the shock-absorbing element at opposite ends of its diameter (Fig. 1).

The first thread with locking elements can be connected to the shock-absorbing element (2) on one side, and the second and third threads with locking elements can be connected to the opposite side of the shock-absorbing element (Fig. 2, 4, 5, 8, 9). The shock-absorbing element can be made in the form of a U-shaped insert, and the threads (1) with locking elements (3) can be connected to the ends of the shock-absorbing element (Fig. 3, 10).

When performing a tissue tightening operation, threads (1) with locking elements (3) connected to a shock-absorbing element (2) with surgical needles (4) enter the tissues and pass through them with their subsequent tension, due to the interaction of locking elements (3) with tissues, after which they are fixed at the point of attachment of the surgical thread (5).

Due to the execution of threads (1) with locking elements (3) having a lower linear density than the shock-absorbing element (2), as well as the execution of the shock-absorbing element (2) with the possibility of attachment to tissues, an enhanced tightening is provided due to the action of the shock-absorbing element, as well as a uniform and optimal distribution of loads caused by tissue tension acting on the threads, shock-absorbing element (2) and the attachment point of the surgical thread (5), as well as the likelihood of damage and inflammation of the tissues surrounding them (1, 2, 3), and also increases the reliability of fastening surgical thread for tissue tightening. At the same time, the execution of threads (1) with locking elements (3) and shock-absorbing element (2) from biodegradable materials reduces the wick effect.

Thus, due to the combination of threads (1) with locking elements (3) in a surgical thread for tightening tissues, connected to a shock-absorbing element (2) from a biodegradable material, and at the same time having a lower linear density than a shock-absorbing element (2) made with the possibility of attachment to tissues, enhanced tissue tightening is provided, uniform and optimal distribution of loads caused by tissue tension with a reduced wick effect, which together ensures the creation of a safe, in terms of tissue inflammation and fastening, surgical thread for tissue tightening, while being easy to perform and manufacture. As a result of the operation, the claimed thread provides enhanced, reliable and safe tissue tightening, which can last for a long time.

As part of the creation of the invention, prototypes (Fig. 6-10) of the claimed surgical thread for tissue tightening were developed and tested. Tests of prototypes (Fig. 6-10) were carried out in accordance with state standards: GOST R 53005-2008 Surgical suture materials General technical requirements. Test methods and GOST 23362-2001 Synthetic textured threads, Method for determining the linear density, as well as taking into account the well-known method for determining the wicking of the suture material (Bontsevich D.N. Capillarity and wicking of the modified and traditional suture material. Problems of health and ecology. 2007; (3 ): 135-140) which showed the implementation of the claimed tissue tightening thread and confirmed the creation of a safe, in terms of tissue inflammation and fastening, surgical thread for tissue tightening, with an easy to perform and manufacture design.

A special case of the description of the technique

For lifting the lower third of the face (mental and submental area), polypropylene threads with converging notches on the needles are used. Modification "C". In the region of the mastoid process, 5 mm away from the ear, an injection is made. Then the needle with the thread passes through the fold to the front surface and there it exits through a 2 mm puncture made in advance. Then the second arm of the thread, making a fixation on the mastoid process, goes into the same hole. A silicone ring is attached to these two threads - a shock absorber with a diameter of 2 mm, a thickness of 1.5 mm and a width of 2 mm. Then, a second notched polypropylene thread is passed through this shock absorber ring and left for now. Then the first thread, both of its shoulders with the help of needles, is carried back to the mastoid process. They unfold there (through a puncture and an injection into the same hole) and, diverging at a distance of 15 mm, go submentally subcutaneously in the direction of the labiomental fold and, not reaching it 5 mm, exit externally. After that, the tension of the soft tissues is done, the threads are cut and the ends are sunk. After that, the two arms of the second thread enter the 2-millimeter hole made, from which they exit, and pass subdermally through the cervical-chin angle with a distance of 40 mm to the opposite side in the projection of the opposite angle of the lower jaw. Then the same manipulation is carried out on the opposite side.
