A new compound curved needle has been developed for skin and skin-graft closure from a unique stainless steel alloy, American Society for Testing Materials (ASTM) 45500. This needle has a short, straight, sharpened point with a reverse cutting edge and a curved distal section. In spite of its geometry, it exhibits sharpness and resistance to bending and breakage similar to that of a needle with a single radius of curvature that is manufactured from the same alloy. The design of this new needle enables the surgeon to pass it through the skin with greater accuracy to a controlled depth and length of bite.
一种新型复合弯针已由一种独特的不锈钢合金——美国材料与试验协会（ASTM）45500制成，用于皮肤及皮肤移植缝合。这种针有一个短而直的尖锐针尖，带有反向刀刃和弯曲的远端部分。尽管其几何形状特殊，但它的锋利度以及抗弯曲和抗断裂能力与由相同合金制成的单一曲率半径的针相似。这种新型针的设计使外科医生能够更准确地将其穿过皮肤，达到可控的咬入深度和长度。
