The technique of follicular unit excision for harvesting grafts for hair transplantation procedures has become very popular. This technique relies on the use of small punches to remove viable grafts. Many different punch shapes have been developed to accommodate the varying nature of skin and hair characteristics, resulting in hair transplant surgeons requiring a variety of punches to suit a wide range of patients, which can be overwhelming to the beginner when trying to decide on the optimal choice of a punch to suit a particular skin characteristic. We describe a novel multipurpose ring punch that can be used on patients with a variety of skin and hair characteristics, as well as for shaved and long hair FUE. Features of this punch include an octagonal ring that protrudes from the outer wall of the punch and functions to control the punch's trajectory into the deeper dermis during incision. Additionally, this punch has a dull, notched edge which allows for use in long hair and shaved FUE without sacrificing ease of incision through the epidermis. This punch is the first of its kind to have this breadth of versatility with a one-size-fits-all design.
毛囊单位提取技术已成为毛发移植手术中非常流行的一种技术。这种技术依赖于使用小打孔器来提取有活力的移植物。已经开发出许多不同形状的打孔器来适应不同的皮肤和毛发特征，这导致毛发移植外科医生需要各种打孔器来满足广泛的患者需求，这对于初学者来说可能是压倒性的，因为他们试图确定最佳的打孔器选择来适应特定的皮肤特征。我们描述了一种新型的多用环形打孔器，可用于具有各种皮肤和毛发特征的患者，以及用于剃发和长发 FUE。这种打孔器的特点包括一个从打孔器外壁突出的八角形环，其功能是在切口时控制打孔器进入更深的真皮的轨迹。此外，这种打孔器具有钝的、有缺口的边缘，允许在长发和剃发 FUE 中使用，而不会牺牲通过表皮的切口的容易程度。这种打孔器是同类产品中第一款具有这种多功能性的设计，一种尺寸适合所有。
