A new compound curved needle has been designed and developed for intradermal suture closure from a unique stainless steel alloy, American Society of Testing Materials (ASTM) 45500. This needle has a short, straight, sharpened point with a reverse cutting edge, followed by a curved distal section. Despite its geometry, it exhibited a similar resistance to bending and breakage as did a curved needle with a single radius of curvature manufactured from the same alloy. The design of this new needle enabled the physician to pass it through the dermis with a greater accuracy to a controlled depth and length of bite than curved cutting edge needle with a single radius of curvature.
一种新型复合弯针已被设计并开发出来，用于采用美国材料与试验协会（ASTM）45500标准的独特不锈钢合金进行皮内缝合闭合。这种针有一个短而直的尖锐针尖，带有反向切割边缘，接着是一个弯曲的远端部分。尽管其几何形状不同，但它与由相同合金制造的具有单一曲率半径的弯针相比，在抗弯曲和断裂方面表现出相似的性能。这种新针的设计使医生能够比具有单一曲率半径的弯形切割边缘针更精确地将其穿过真皮，达到可控的咬入深度和长度。
