Definitions

  • the present Invention relates to threads used in aesthetic surgery and surgical interventions, provided with an innovative conception and important practical and functional improvements in conformity with the required specifications and norms; having innovative and proper characteristics, provided with essential requirements of novelty and inventive act, which results in a series of actual and extraordinary advantages inherent to its applicability and usability.
  • the said threads used in aesthetic surgery and surgical interventions also known as "up thread", are used in face lifting procedures. These surgeries are performed in regions having facial flaccidity, since they are previously analyzed and diagnosed by a specialist in the subject. Generally, they are used to attenuate, alleviate or prevent wrinkles, facial grooves, neck flaccidity, lifting eyebrows, among others.
  • the up thread is made of polypropylene, which is a non-biodegradable and biocompatible material with strong resistance, and inert in the human organism. It is the same material of threads used in internal sutures, which is used in other types of surgeries; however, up threads used in aesthetic surgeries have small hooks projecting from the proper thread. These hooks are important for the desired aesthetic function, since they have a tensioning function to combat flaccidity, as well as they are responsible by the fastening of the thread in the patient, where they are implanted in the facial subcutaneous adipous tissue, above the muscular layer.
  • the action of the tensions created by the shape of the hooks of the up thread makes the sagging region presents a traction force, lifting the tissues and helping to minimize the effect of flaccidity that the patient already has or will acquire over the years.
  • the lifting of sagging tissues is also enhanced by the natural reaction of the organism, which stimulates the production of elastin and collagen around the thread, transforming the polypropylene thread into a supporting ligament of facial soft tissues.
  • a thread comprises two coplanar tiny cogs or barbs directed upwardly and a tiny cog or barb in the inverse direction, i.e., they are directed downwardly, in a plane perpendicular to the two parallels.
  • This thread is intended to attend an activity comprising two forces, wherein the first is a supporting force that does not allow the soft tissue to return to the original position after it has been implanted; and the second is a traction force that will elevate the soft tissues to a higher position.
  • the threads of the present invention instead of the hooks being directed only to a determinate direction, as in up threads known in the state of the art, the threads of the present invention have hooks in opposite direction, wherein the said hooks are disposed in a plane perpendicular to the other hooks.
  • the thread used in aesthetic surgery and surgical interventions of the present invention is advantageous in relation to the threads known in the state of the art, by the fact that produces an additional fastening and traction forces on the sagging tissues, in a more efficient way; produces greater tension on the region that is desirable to recover; and allows the action of these additional hooks to provide a better distribution of tension of the thread on the tissues.
  • the tension generated is lower in relation to the threads having additional hooks disposed in pairs.
  • the set of tiny cogs or barbs works with a coplanar pair, a perpendicular pair, and with a pair of tiny cogs or barbs displaced from this set, in an opposite direction.
  • this thread has a combination of traction and supporting, wherein the four tiny cogs or barbs disposed upwardly at the superior segment (two and two perpendiculars) are intercalated with a pair of coplanar tiny cogs or barbs to assist in inhibiting the return of the tissue, providing an efficient alternative, when required by the tissue.
  • the direction is inversed.
  • this second embodiment of the present invention looks for a supporting as the main action, which is intercalated with a secondary single traction, i.e., four tiny cogs or barbs (two coplanar and two perpendicular), which, when they are downwardly, they exert a supporting intercalated by a pair in a opposite direction, and when they are upwardly, they exert a secondary traction.
  • a secondary single traction i.e., four tiny cogs or barbs (two coplanar and two perpendicular)

  • the thread used in aesthetic surgery and surgical interventions of the present invention is advantageous in relation to the threads known in the state of the art, by the fact that it produces traction and supporting force on the sagging tissues, in a more efficient way; moreover, it looks for a supporting as the main action, which is intercalated with a secondary single traction, on the region that is desirable to recover, wherein the action of these tiny cogs or barbs allows a better distribution of tension of the thread on the tissues.

  • the set of tiny cogs or barbs works with a coplanar pair and a perpendicular pair, wherein the tiny cogs or barbs of the superior segment are disposed upwardly and the tiny cogs or barbs of the inferior segment are disposed downwardly.
  • This arrangement aims to pull when the doctor observes that the tissue is softer than others, since the said four tiny cogs or barbs which are directed to only a direction tend to exert more effort than to the double and perpendicular tiny cogs or barbs.
  • the said four tiny cogs or barbs are in an inverse direction to stop the return of the tissue, consequently, the application of the thread is not only destined to re-lift the facial tissue, but also other tissues, justifying the necessity of adjusting the traction and the positions of the tiny cogs or barbs, according to their ease of firming the tissue.
  • the thread will exert traction, as the main action; and if the tiny cogs or barbs are directed downwardly at the superior segment of the thread, the thread will exert supporting, as a secondary action; therefore, as the implanted superior segment of the thread will make the traction effort, it is placed upwardly.

  • the application of threads with additional hooks, whether single or in pairs, as well as the application of threads with tiny cogs or barbs will depend on the clinical conditions of the patient to be evaluated by the specialist.

Abstract

L’invention concerne des fils, également connus sous le nom de « fils de relèvement », qui sont utilisés dans les interventions de rhytidectomie. Ces actes chirurgicaux sont réalisés dans des régions présentant une certaine flaccidité faciale analysée et diagnostiquée au préalable par un spécialiste en la matière. Ils servent généralement à atténuer, réduire ou éviter les rides, les sillons faciaux, la flaccidité du cou, l’affaissement des sourcils, entre autres.
