In this case, the coil shape is easily elastically deformed, and thus, the yarn 120 is arbitrarily moved at the treatment site by the forces F1 and F2 (for example, in FIG. 15, left side LSD or right side RSD).

Therefore, the thread 120 is stably filled in the treatment site to improve the sagging or wrinkles (L) of the skin (S) can effectively produce a treatment effect on the treatment site.

Abstract

La présente invention concerne un dispositif d'insertion de fil pour enrouler densément un fil autour de la circonférence d'une aiguille d'insertion et nouer une partie d'extrémité arrière du fil densément enroulé autour de la circonférence de l'aiguille d'insertion. Le dispositif d'insertion de fil selon un mode de réalisation comprend : l'aiguille d'insertion ayant une extrémité pointue et comprenant un trou qui est formé dedans, s'étendant dans une direction longitudinale et ouverte vers la pointe ; et le fil comprenant une première partie allongée insérée dans le trou de l'aiguille d'insertion, une partie d'enroulement s'étendant depuis la première partie allongée et enroulée autour de la circonférence de l'aiguille d'insertion dans le sens longitudinal de l'aiguille d'insertion sur le côté extérieur du trou de l'aiguille d'insertion, et une seconde partie allongée pour former une partie de nœud attachée de manière à empêcher le déroulement de la partie d'enroulement, dans lequel, lorsque le fil est inséré dans le corps humain par l'aiguille d'insertion, la partie d'enroulement est amenée à l'intérieur du corps humain et reste dans celui-ci dans une forme dans laquelle la partie d'enroulement est densément enroulée autour de la circonférence de l'aiguille d'insertion.
