A curved Mayo scissor is a heavy-duty surgical scissors designed mainly for cutting thick, dense tissue and, in many settings, sutures or dressings. The curved blade gives better access into deeper operative fields, while the blunt, robust build helps reduce accidental damage to nearby structures.Mayo scissors come in straight and curved forms and in different lengths; the curved version is typically used for deeper dissection and cutting thick tissue, while the straight version is often used for sutures. They are generally larger and sturdier than finer dissecting scissors, with a design aimed at power and control rather than delicate precision.
