Definitions

  • the present invention relates to a surgical thread for use in plastic surgery, and more particularly to a surgical thread, which is made of a polymer material having excellent elasticity and resilience and has open pores formed on the surface thereof, such that the surgical thread can be infiltrated with tissue cells after a surgical operation and, at the same time, can move integrally with skin tissue upon the contraction and relaxation of muscles, whereby the surgical thread can show excellent effects upon surgical lifting or sling operations for face wrinkles, neck, breast, buttocks and the like.
  • a surgical method which has been used for the longest method, is face lift for making the skin tight by lifting up the skin, removing the excess of the skin and then closing the incision with sutures, but this surgical method is highly risky in itself, even though it has a rapid effect. Also, it can leave scars in front of the ear and the forehead and requires a recovery period of about 6 weeks, and thus cannot be readily selected. Furthermore, the method has shortcomings in that, because aged skin remains as it is, wrinkles continue to progress, and the skin becomes thinner, and thus the aging thereof is facilitated.
  • the surgical threads all have protrusions formed on the outer surface thereof, in which these protrusions serve to pull the skin by firmly engaging with dermal muscles slack in the skin and to restore skin firmness.
  • the protrusions have a sharp tip portion, they can irritate nervous tissue to cause pain. Also, because the protrusions are conical in shape, they can project out of the skin, when they are not firmly fixed in the skin.
  • the products are made of a plastic or polymer material having no elasticity in itself, they firmly engage with dermal muscles after insertion, so that they cannot follow the movement of human tissue that elastically moves as the skin is pulled. For this reason, when persons inserted with the products laugh, yawn, or chew food, the products can give foreign-body sensations and result in an unnatural look or facial shape.

  • the difference in diameter between the center portion 40 and the body portion is preferably about 0.5-1.5 mm.
  • the thickness is limited to said thickness is that said thickness is allowed to minimize a possibility for the surgical thread to be felt, and minimize the diameter of a tissue tunnel into which the thread is inserted during a surgical operation.
  • center portion 40 and the body portion 50 can be made to have different diameters through a conventional thread forming process.
  • the open pores 20 are formed over the entire length of the center portion 40 and the body portion 50 except for the end portion 60.

Abstract

L'invention concerne un fil destiné à une utilisation dans la chirurgie plastique, et fabriqué à partir d'un polymère possédant une élasticité et une résilience excellentes, ainsi que des pores ouverts sur leur surface. Le fil chirugical de l'invention est fabriqué à partir de polyorganosiloxane, notamment du diméthylsiloxane, un dérivé ou un copolymère de celui-ci, à élasticité et résilience excellentes et qui convient à la greffe, pouvant ainsi se déplacer solidairement avec les tissus cutanés lors de la contraction et de la décontraction des muscles et, ménagés sur sa surface, des pores ouverts au lieu de saillies pointues, de manière à pouvoir être aisément infiltrés de cellules tissulaires après des opérations chirurgicales. Le fil chirurgical n'entraîne en outre aucun effet secondaire après des opérations chirurgicales, peut être utilisé de façon semi-permanente, et peut donner satisfaction aux patients, puisqu'il améliore grandement les effets de la rhytidectomie ou de la fronde chirurgicale.
