Abstract:
Follicular unit excision is widely used for hair transplantation because it lacks a donor scar and is associated with less postoperative pain. Obtaining high-quality grafts and minimizing hair follicle damage during graft harvesting are key. This review elaborates on the types and dynamics of punches used in follicular unit extraction. We also describe the utility and advantages of a new \"Multi-Wave Punch,\" a new type of punch designed to optimize graft extraction and reduce follicular injury. This multi-wave punch is composed of three different parts. The cutting edge at the end is blunt-angled. Adjacent is the leading edge, which is characterized by several horizontally oriented multi-wave shapes. Most proximal is the main body, which is decagonal in shape. Because of the multi-wave and decagonal structure, the punch easily enters the outer layers of the scalp. The wave energy is transmitted to the surrounding tissue, separating hair follicles from adjacent tissue, facilitating extraction, reducing follicular damage, and ensuring higher quality grafts.
摘要:
毛囊单位切除广泛用于毛发移植,因为它没有供体疤痕,并且术后疼痛较少。获得高质量的移植物并在移植物收获期间最大限度地减少毛囊损伤是关键。本文综述了毛囊单位提取中使用的冲头的类型和动力学。我们还描述了一种新的“多波冲床”的效用和优点,“一种新型的冲头,旨在优化移植物提取并减少卵泡损伤。这种多波冲头由三个不同的部分组成。端部的切削刃是钝角的。相邻的是前缘,其特点是几个水平定向的多波形。最接近的是主体,形状是十角形的。由于多波和十边形结构,冲头很容易进入头皮的外层。波能传递到周围的组织,从邻近的组织中分离毛囊,促进提取,减少卵泡损伤,并确保更高质量的移植物。
