Novel Follicular Unit Excision Device That Reduces Graft Injury and Improves Ergonomics in Hair Transplantation Surgery

Abstract

Purpose: Follicular unit excision (FUE) surgery is becoming increasingly popular and the number of grafts transplanted in a single session is increasing. Furthermore, complicated surgeries and those requiring a longer surgical time such as non-shaven FUE and long hair FUE are more actively being performed worldwide. The main aim in FUE surgery is to obtain the best quality grafts while minimizing follicular damage during donor harvest. This article describes a novel FUE device that achieves these goals. Patients and Methods: We describe a novel FUE device with Bluetooth function, fingertip touch sensor, multiphasic movement, automated operation by setting the interval time between punching motions, ergonomic design, various innovative functions, and an easily upgradable application used to operate the handpiece. We also report the concept of design, mechanism of action, methods of use, and effect of each innovative function. Results: The various state-of-the-art features of the device minimize the risk of follicular injury when working with a wide variety of scalp and hair follicle types and conditions. In addition, it enables successful donor harvesting by reducing the surgeon’s workload and improving ergonomics. Conclusion: We introduce an innovative and new device for use in FUE surgery. This novel device has the potential to increase the convenience, scalability, and safety of FUE surgery.
