Abstract

La présente invention concerne un instrument pour le prélèvement et l'application de greffons capillaires folliculaires humains au moyen d'aiguilles jetables, offrant une solution pratique, simple, efficace et peu coûteuse, et dont la fonction (greffe de cheveux humains) peut être sensiblement améliorée avec des économies en temps, en coût et en personnel, par comparaison avec l'opération fastidieuse et très coûteuse de l'état actuel de la technique au niveau mondial, qui consiste à couper de nombreuses bandes de peau chevelue, à les diviser une par une en petits morceaux présentant entre 1 et 3 follicules par greffon, et à les implanter manuellement dans leur lit récepteur. Selon la présente invention, un appareil unique permet à une personne seule de réaliser (économiser) le travail de 7 personnes. En effet, ledit équipement permet non seulement de couper les greffons pileux, mais aussi de les préparer, de les sectionner, de les saisir, de les disposer individuellement ou par groupes de 3 en ligne. Il permet non seulement de les transporter dans l'aiguille, mais également de les préinjecter dans les lits récepteurs et de les réimplanter, avec un taux de croissance et de développement atteignant 100%. Ledit appareil est maniable, portable et léger. Il est démontable et polyvalent et permet de réaliser plusieurs fonctions à la fois de manière simultanée. En outre, il peut être manié par une seule personne. L'invention concerne un appareil manuel mécanique pneumatique pourvu d'aiguilles à pointe carrée ou ronde, facilitant le prélèvement et l'application de greffons de peau chevelue humaine et permettant de prélever sélectivement les unités folliculaires en îlots sans endommagement des follicules ou du plexus sous-jacent. Ces modifications se traduisent par un fonctionnement amélioré, ledit appareil présentant une meilleure efficacité, occasionnant moins de lésions des follicules et permettant d'obtenir un taux de survie accru.
