Definitions

  • the present invention relates to a method for the percutaneous implantation of artificial hair using an implantation needle.
  • the object of the invention is now to improve the percutaneous implantation method of the aforementioned type so that complications such as post-implantative or. post-operative infections practically no longer occur or removal of the implanted hair is readily possible.
  • an uncomplicated implantation of artificial hair can be expected from the known state of the art, as long-term trials and clinical studies can demonstrate. Since the main causes of post-implantative resp. post-operative infections, namely interface at the inner end of the thread and sharp-edged deformation at the welding point of the overlapping parts of the thread relocated to the outside or infections are completely avoided, infections hardly occur. If removal of an implant still appears advisable, it can also be easily removed while avoiding the usual injuries by first pulling alternately on both ends of the hair, so that the thread is gently but continuously completely detached from its changes and then released without any significant resistance one or the other side is pulled out. The latter is also possible if the implant is provided in the area of the planted bay with one or more knots forming abutments against tension.
  • Another very significant advantage is that by implanting a double hair with a needle stroke, which results in a significantly higher hair density with a comparatively same implantation density.
  • plastic threads are available as material for the implant, which have emerged from corresponding chemical and biological tests, such as polyester resin single threads of 0.06 to 0.1 mm in diameter, which are produced by melt spinning a linear polymer from polyethylene terephthalate become. These threads are characterized by extremely low toxicity, high heat resistance and a feeling close to natural hair.
  • the implantation needle to be used can be of a conventional type.
  • the method according to the invention can be used at any point on the body, for example for cosmetic corrections of the main or whiskers.
  • a double hair is formed, the bay 2 of which, if necessary, see with one or more nodes 2 ', by means of a conventional implantation needle (not shown in detail) while penetrating the epidermis 3 and corium 5 into the deep part of the subcutaneous tissue 7.
  • the bay and subsequent inner hair sections of the implant are completely surrounded by fibrous connecting tissue 9 and the implant is thus fixed.

Abstract

En implantant un filament synthétique (1) replié, on obtient un cheveu double dont l'anse (2) constitue la racine implantée. Une croissance du tissu autour de l'anse de chaque cheveu implanté permet la fixation par un tissu de soutien (9). Par ce procédé, on évite en particulier des infections après implantation ou après opération.
