Searching for a labeled Mayo scissors diagram usually means you're trying to identify a specific part of the instrument—for training, procurement, or instrument tray verification. This guide breaks down the anatomy of a Mayo scissor and the sizes commonly stocked in surgical trays.

Mayo scissors: labeled parts

A Mayo scissor has four main anatomical parts, moving from tip to handle:

  • Blade tip — the cutting point, either straight or curved depending on the pattern.
  • Blade — the cutting edge running from the tip to the box lock, thicker and more robust than those of dissecting scissors like Metzenbaum.
  • Box lock (pivot joint)—the hinge point where the two halves of the scissor cross and pivot.
  • Finger rings (bows)—the loops the surgeon's thumb and ring finger pass through to control the blades.

Straight vs. curved Mayo scissors

Straight Mayo scissors are typically used for cutting sutures and dense tissue like fascia, where a direct line of sight and cutting force matter more than maneuverability.

Curved Mayo scissors are preferred for dissection in confined or deeper areas, since the curve lets the surgeon see around the blade tip during use.

Mayo scissors size guide

Mayo scissors are typically stocked in the following lengths, with longer sizes used for deeper access:

  • 5.5" (14cm) — fine work, shorter reach procedures
  • 6.75" (17cm) — general-purpose, most common tray size
  • 7.5" (19cm) — standard for abdominal and gynecological procedures
  • 9" (23cm) — deeper access, larger body habitus, or bariatric procedures

Gulmaher Surgico stocks Mayo scissors across these sizes in both straight and curved patterns, including the Mayo-Lexer, Mayo-Noble, and Mayo-Stille variants. Browse our Mayo scissors range or contact us for bulk or custom specifications.
