Types of Surgical Scissors: Patterns, Blade Geometry & Clinical Uses

Surgical scissors vary significantly in blade thickness, shank-to-blade ratio, tip geometry, and alloy hardness. Selecting the wrong pattern accelerates blade dulling and compromises tissue handling.

1. Mayo Dissecting Scissors Mayo scissors feature semi-blunt, sturdy blades with a shorter handle-to-blade ratio. Straight Mayo scissors are commonly reserved for cutting sutures and dressings, while curved Mayo patterns dissect denser fascia and heavy connective tissue.

2. Metzenbaum Dissecting Scissors Metzenbaum scissors pair long handles with slim, tapered blades engineered exclusively for delicate soft-tissue dissection. Using Metzenbaum blades on heavy sutures or gauze quickly misaligns the tips.

3. Operating, Iris & Tenotomy Patterns - **Operating Scissors:** Standard sharp/blunt, sharp/sharp, or blunt/blunt utility patterns for general dressing and suture work. - **Iris Scissors:** Compact 10–11.5 cm fine-point scissors used in ophthalmic, dermatologic, and precise superficial trim work. - **Tenotomy Scissors:** Precision micro-tips (such as Stevens Tenotomy) designed for confined surgical fields.
