A challenge in follicular unit excision (FUE) is the lack of a single device that can adequately meet the requirements of a range of patient donor variables, such as hair curliness, race, body and head hair locations, and non-shaven short- and long-hair FUE. This study aimed to describe a novel FUE device developed based on skin responsiveness to serve as a single all-purpose FUE donor harvester.
We describe an all-purpose FUE device that consists of an all-purpose punch and a functionally complementing punch driver. The mechanism of action and method of use are reported. Several patients with a diversity of FUE challenges for three experienced FUE practitioners using the novel device are presented using photos and videos. The practitioners also reported their comparative experiences with using prior FUE systems in similar situations.
The novel device demonstrated success in a variety of FUE scenarios without requiring specialized provider skills. The device responds to changing skin firmness and thickness, which are the primary causes of inconsistent performance in FUE devices between patients and within patients from one body/head area to another. It also minimized challenges of unpredictable hair curliness and angles by its innate ability to self-navigate the subsurface course of hair follicles, to which the FUE practitioner is typically blinded.
We describe a novel FUE device that overcomes the challenges of previous FUE technologies and has potential applicability to a diverse range of FUE scenarios. Our experience suggests that further validation is warranted.
毛囊单位提取（FUE）面临的一个挑战是缺乏一种能够充分满足一系列患者供体变量要求的单一设备，这些变量包括头发卷曲度、种族、身体和头部毛发位置，以及非剃发的短发和长发FUE。本研究旨在描述一种基于皮肤反应性开发的新型FUE设备，用作单一的通用FUE供体采集器。
我们描述了一种通用FUE设备，它由一个通用打孔器和一个功能互补的打孔驱动器组成。报告了其作用机制和使用方法。展示了几张照片和视频，呈现了几位患者面临各种FUE挑战，三位经验丰富的FUE从业者使用这种新型设备为他们进行治疗的情况。这些从业者还报告了他们在类似情况下使用先前FUE系统的比较经验。
这种新型设备在各种FUE场景中均取得了成功，且无需专业医生技能。该设备能够应对皮肤硬度和厚度的变化，而皮肤硬度和厚度变化是导致不同患者之间以及同一患者身体/头部不同区域之间FUE设备性能不一致的主要原因。它还凭借其天生的自行在毛囊皮下路径导航的能力，将不可预测的头发卷曲度和角度带来的挑战降至最低，而FUE医生通常对此并不了解。
我们描述了一种新型FUE设备，它克服了以往FUE技术的挑战，并且在各种FUE场景中具有潜在的适用性。我们的经验表明有必要进行进一步验证。
