HAIR FOLLICLE CORING TOOL AND SYSTEM BASED THEREON

摘要

A tool for coring a portion of one or more hair follicles incorporates an elongate hollow tubular member with at least one cut-out disposed between its distal end and proximal end. The cut-out allows for removal of debris that moves it way up the hollow tubular member from the opened distal tip. The needle can also include a radially-extending projection that cooperates with zero or more ring-shaped members that are slipped concentrically over the distal end of the hollow tubular member to set the penetration depth of the coring needle. The tool can also include a stepped interface that is adapted to snag a root of a hair follicle unit cored by the hollow tubular member upon its withdrawal away from the patient's body.
