Definitions

  • Thread for tightening the soft tissues of the face and body
  • the invention relates to materials for lifting the soft tissues of the face and body (hereinafter referred to as lifting) and can be used in plastic surgery, surgery, cosmetology, dermatovenereology, gynecology.
  • Threads containing locking notches for fixation in tissues are widely known. Examples of such threads are lifting threads known from the descriptions to patents RU 2584079 C1, 05/20/2017, RU 2 341 210 C2, 12/20/2008 or US 8267961 B2, 09/18/2012.
  • the disadvantages of the known threads include their slight elastic stretch in the axial direction, which depends only on the properties of the thread material.
  • the need to select the shape of the locking notches for fabrics of different thicknesses and densities is another disadvantage of the known threads.
  • the closest analogue of the invention is a thread containing a base with pointed ends and locking notches for fixation in tissues (RU 2528077 C1, 09/10/2014).
  • the thread known from the description to the patent RU 2528077, can be used for lifting and can be made with locking notches of various shapes for fabrics of various thicknesses and densities, but it has a slight elastic stretch in the axial direction.
  • the invention is aimed at solving the technical problem of creating a thread for lifting with an elastic effect, which, if necessary, can significantly elongate when stretched and contract when the axial load is removed to provide a tissue lifting effect.
  • the technical result of the invention is to provide maximum and adequate tissue lifting, both in areas with a high mechanical load on tissues (tissue lifting of the upper and lower extremities, chest, abdomen, tissue lifting in the perineum), and in areas with minimal mechanical load on tissues. (during face and neck tissue lifting), due to a specific thread design.
  • lifting using the thread of the claimed design has many advantages, namely: reliable fixation in the tissues; elasticity; the ability to lift "heavy"tissues; due to the larger area (when unfolding the thread), there is no contouring of the thread through the skin; achieving a lasting effect; when used as a suture material, it securely fixes the edges without contact of the thread with the outer surface of the skin.
  • the thread for lifting contains a flexible base, including a section on which pairwise parallel locking sections are made, connected by jumpers, while each of the locking sections is oriented to the longitudinal axis of this section at an angle of 5 - 90 ° , has pointed ends or rounded ends or rounded ends with pointed ends, oriented with ends or pointed ends in opposite directions, and the possibility of fixation in tissues across the longitudinal axis of the section of the locking segments, moreover, the jumpers are made with the possibility of connecting their ends with opposite ends of the locking segments or connecting the ends of the jumpers with the centers of the locking segments.
  • the flexible base of the thread may contain pointed ends.
  • the pointed ends of the base can be made in the form of arrow-shaped tips (arrows), as well as a one-sided hook (harpoon).
  • a ligature eye may be contained.
  • the thread for lifting may contain a flexible base with a diameter of 0.05 mm to 2.0 mm. Thanks to this fact, it is possible to manufacture a thread for a specific application. So, for example, thicker threads can be used in areas with more “heavy” tissues or areas with increased mechanical stress (lifting in the areas of the upper and lower extremities, chest, abdomen, perineum). Thin threads can be used in areas with thinner skin (face and neck area).
  • the base of the thread may additionally contain at least one smooth section at one or both ends of the base and / or a section containing locking notches (possible arrangements: two-sided symmetrically / asymmetrically located, “arrow-shaped” elements, one-sided symmetrically / asymmetrically located, " arrow-shaped "elements) for fixation in tissues.
  • a section with locking notches can be located at the end of the thread for reliable fixation of the distal end of the thread and additional fixation of the lifting effect.
  • the section with stop notches can also be located in the center of the thread between 2 sections with stop cuts.
  • the section on which pairwise parallel locking sections are made, connected by bridges, is located between the smooth sections of the thread.
  • the ends of the locking segments are connected by a jumper asymmetrically, that is, the end of one locking segment is connected to the opposite end of the other locking segment. Moreover, the closer to the ends the fixation occurs, the less force is required to straighten the locking segments when the thread is tensioned. Due to this fact, it is possible to manufacture threads with different force of opening of the locking segments.

  • Example 1 Patient M, 48 years old. As a result of various procedures (cryolipolysis, massage, lymphatic drainage, etc.) and following a strict diet, she dramatically reduced body weight by 45 kg. Examination revealed deep nasolabial folds, ptosis of the upper eyelid, hernia of the lower eyelid, deformity of the facial contour, hypotension of the buccal regions. When examining the body, a transverse fold of subcutaneous fat 5 cm thick was found on the anterior abdominal wall (the measurement was carried out with a caliperometer).
  • a thread with the construction shown in Fig. 22 We used a thread with a diameter of 2 mm and with an inclination of the stop segments 10 located first at an angle of 50° and then fixed in the tissues at an angle of 90°. This provided a significant tightening of tissues with a high mechanical load. As a result, the transverse fold of subcutaneous fat decreased by 1.5 cm.

Abstract

L'invention concerne des matériaux pour retendre des tissus mous du visage et du corps (lifting) et peut être utilisée en chirurgie plastique, en chirurgie, en cosmétologie, en dermatologie et en gynécologie. Ce fil pour lifting comprend une base flexible comprenant une section sur laquelle sont formés par paires des entailles d'amortissement parallèles connectées par des pontets; chacune des entailles d'amortissement est orientée vers l'axe longitudinal de la section donnée selon un angle de 5-90°, possède des extrémités aiguës ou des extrémités arrondies ou des extrémités arrondies avec des pointes aiguës, orientées au niveau des extrémités ou des pointes aiguës vers les côtés opposés en vue de la fixation dans les tissus transversalement à l'axe longitudinal de la section des entailles d'amortissement; les pontets sont réalisés de manière à ce que leurs extrémités soient connectées aux extrémités opposées des entailles d'amortissement de section ou afin de connecter les extrémités des pontets avec les centres des entailles d'amortissement. Cette invention permet un lifting maximal et adéquat des tissus tant dans les zones présentant une contrainte mécanique élevée que celles présentant une contrainte mécanique minimale sur les tissus grâce à une structure donnée du fil de lifting.
