Abstract

Cette invention concerne un scalpel (11) avec une pointe acérée, un tube de guidage (12) logé contre le scalpel et une aiguille d'insertion (13) dont la partie d'extraction du cheveu (13a) située en bout de scalpel traverse le tube de guidage, tous ces constituants étant logés coulissant dans un corps (10). La partie d'extraction du cheveu (13a) vient s'accrocher sur la racine (31a) du cheveu (31) cependant que l'aiguille d'insertion s'insère dans le tube de guidage. Le scalpel peut dépasser d'une longueur spécifiée hors du corps de manière à pénétrer dans un tissu sous-cutané (46). De même, le tube de guidage renfermant l'aiguille d'insertion peut pénétrer dans le tissu sous-cutané par une incision pratiquée au moyen du scalpel. L'aiguille d'insertion reste en place dans le tissu sous-cutané (46) afin que la racine du cheveu soit retenue par la partie d'extraction de la racine pendant le rappel du scalpel et du tube de guidage, puis cette aiguille est elle-même rappelée dans le corps. Cette technique et ce dispositif permettent de transplanter les racines capillaires de manière uniforme, sans risque d'écrasement desdites racines, sans hémorragie importante, rapidement, pour une croissance normale des cheveux.
