Abstract

La présente invention concerne un dispositif d'évaluation de cheveux pour une chirurgie de greffe de cheveux, qui : capture des images de cheveux collectés pendant une chirurgie de greffe de cheveux et, sur la base d'informations d'image, mesure l'état des cheveux, comme l'épaisseur des cheveux et le point de savoir si la surface des cheveux est ou non endommagée ; affiche le nombre total de follicules pileux en temps réel ou guide l'emplacement et la distribution d'une greffe de cheveux à l'intérieur d'une zone de greffe de cheveux ; affiche le nombre de cheveux greffés en temps réel, réduisant ainsi la fatigue d'un chirurgien pendant une chirurgie ; permet même à un médecin ayant peu d'expérience chirurgicale d'effectuer sans problème une chirurgie de greffe de cheveux en réduisant la difficulté de la chirurgie ; et peut augmenter la satisfaction d'un patient de greffe de cheveux par l'intermédiaire d'une chirurgie de greffe de cheveux planifiée.
