Advances in Hair Transplantation Technology: Multiphasic Device for Follicular Unit Excision

Skinmed. 2019 Jul 1;17(4):241-246. eCollection 2019.

Abstract

Follicular unit excision (FUE) requires the careful excision of hair-bearing follicular units. The follicle can only be detached from the skin once the epidermis, dermis, and subcutaneous tissues are cut, and each layer requires a different amount of force. Traditional FUE devices can be set only to a single speed during a single excision. The Trivellini Device is a first-in-class programmable multiphasic device that is able to accommodate the cutting of various layers of tissue in a single program, while ensuring minimal transection of hair grafts. We detail the advances in the field of motorized FUE embodied by the multiphasic devices.
