Follicular unit excision (FUE) is used to harvest follicular units for hair transplantation using trephine punches. The characteristics of FUE punches can impact the success of this technique; thus, many innovative punch designs and devices have been developed. With many options available, it can be difficult for the hair restoration surgeon to know which punch best suits the needs of their patients.
To provide a comprehensive review of punch shapes and devices available.
Search of PubMed, reference mining of relevant publications, and hand searching trade publications.
We examined FUE punches and devices and consolidated descriptive information for each to create textual and visual guides. No single punch shape or device may suit all cases; thus, it is important to know the best uses and limitations of each.
The surgeon should have a comprehensive knowledge base of available punch shapes and devices and understand the advantages and disadvantages of each. It is also beneficial to have an in-depth knowledge of skin properties and follicular unit structure. Ultimately, understanding the dynamics behind punch excision will enhance the FUE technique.
毛囊单位提取（FUE）使用环钻打孔器来提取毛囊单位进行毛发移植。FUE 打孔器的特点会影响该技术的成功，因此，许多创新的打孔器设计和设备已经被开发出来。由于有许多选择，毛发修复外科医生很难知道哪种打孔器最适合患者的需求。
提供可用的打孔器形状和设备的全面综述。
在 PubMed 中搜索，参考相关出版物的挖掘，以及手工搜索贸易出版物。
我们检查了 FUE 打孔器和设备，并对每个设备的描述信息进行了整合，以创建文字和视觉指南。没有一种打孔器形状或设备可以适用于所有情况，因此，了解每种设备的最佳用途和局限性非常重要。
外科医生应该全面了解可用的打孔器形状和设备，并了解每种设备的优缺点。深入了解皮肤特性和毛囊单位结构也很有帮助。最终，了解打孔器切除的背后的动态将增强 FUE 技术。
