A new compound curved tapercut needle has been designed and developed for oral mucous membrane closure from a unique stainless steel alloy, American Society for Testing Materials (ASTM) 45500. This tapercut needle has a short, relatively straight point, followed by a curved distal section. Despite its geometry, it exhibited similar sharpness as well as resistance to bending and breakage, as did the standard tapercut needle with a single radius of curvature manufactured from the same alloy. The design of this new needle enabled the surgeon to pass it through the oral mucous membrane with a greater accuracy to a controlled depth and length of bite than the standard tapercut needle with a single radius of curvature. In addition, the new needle design aids in the suturing of mucous membranes in confined spaces.
一种新型复合弯曲斜角切割针已被设计并开发出来，它由一种独特的不锈钢合金——美国材料与试验协会（ASTM）45500制成，用于口腔黏膜闭合。这种斜角切割针有一个短的、相对较直的针尖，后面跟着一个弯曲的远端部分。尽管其几何形状不同，但与由相同合金制造的具有单一曲率半径的标准斜角切割针相比，它表现出了相似的锋利度以及抗弯曲和抗断裂性能。这种新型针的设计使外科医生能够比具有单一曲率半径的标准斜角切割针更精确地将其穿过口腔黏膜，达到可控的咬合深度和长度。此外，这种新型针的设计有助于在狭窄空间内缝合黏膜。
