A hair transplantation device can include a generally tubular guide configured to locate a hair follicle bulb by sliding over a hair shaft down to an upper surface of a hair follicle. The guide can have a blunt distal end configured not to transect the hair follicle bulb. The hair transplantation device also includes an outer tubular member sized and configured to be advanced around the guide. The outer tubular member has a dilator and a harvester. The device can be used in a follicle transplantation method in which the guide locates a hair follicle bulb, and the outer tubular member is slid over the guide. Once the outer tubular member is aligned with the guide, the harvesting portion is advanced, cutting dermal tissue surrounding the hair follicle. The outer tubular member is then withdrawn with the hair follicle, relocated in a recipient area, and the hair follicle implanted.
L'invention concerne un dispositif de transplantation de poils comprenant un guide de forme générale tubulaire conçu pour localiser un bulbe de follicule pileux par coulissement sur une tige pilaire vers la surface supérieure d'un follicule pileux. Le guide peut comprendre une extrémité distale émoussée conçue pour ne pas infecter le bulbe de follicule pileux. Le dispositif de transplantation de poils comprend également un élément tubulaire externe dimensionné et conçu pour être avancé autour du guide. L'élément tubulaire externe comprend un dilatateur et un élément de recueil. Le dispositif peut être utilisé dans un procédé de transplantation de follicules dans lequel le guide localise un bulbe de follicule pileux et l'élément tubulaire externe est coulissé sur le guide. Une fois l'élément tubulaire externe aligné avec le guide, la partie de recueil est avancée, coupant le tissu dermique entourant le follicule pileux. L'élément tubulaire externe est ensuite retiré avec le follicule pileux, replacé dans une zone de destination et le follicule pileux est implanté.
