1. Scissors

• Mayo Scissors: Used for cutting heavy body tissues or sutures; available in straight (sutures) or curved (fascia) types.
• Metzenbaum Scissors: Lightweight, used for cutting delicate, soft tissues and in blunt dissection.
• Iris Scissors: Fine, micro-scissors used for precise, delicate tissue work.

2. Forceps & Clamps

• Artery Forceps (Hemostats): Locking clamps used to control bleeding (e.g., Mosquito, Crile, Kelly forceps).
• Tissue & Dressing Forceps: Standard, non-locking grasping tools (e.g., Adson Plain and Toothed forceps).
• Sponge Holding Forceps: Used to securely hold and manipulate surgical swabs/sponges without damaging surrounding tissue.
• Towel Clips (Backhaus): Used to secure surgical drapes and towels to the patient’s skin.

3. Retractors

• Handheld Retractors: Used by assistants to hold incisions open (e.g., Langenbeck or Deaver retractors).
• Self-Retaining Retractors: Mechanically hold themselves open, allowing hands-free operation (e.g., Gelpi, Weitlaner, or Alm retractors).

4. Needle Holders

• Mayo-Hegar Needle Holder: Standard, heavy-duty grip for larger, robust surgical needles.
• Olsen-Hegar Needle Holder: Combines a needle holder with built-in scissors, primarily used in delicate or routine suturing.

1. Cutting and Dissecting Instruments

Used for making incisions, dissecting tissue, and cutting sutures.

• Scalpel Handles: Common sizes include No. 3 (fits No. 10, 11, 12, and 15 blades) and No. 4 (fits larger blades like No. 20).
• Mayo Scissors: Heavy scissors used to cut thick tissues; available with straight or curved blades.
• Metzenbaum Scissors: Finer, longer scissors used for delicate tissue dissection.
• Iris Scissors: Delicate, small scissors primarily used in ophthalmic or precise facial/neurological surgery.

2. Grasping and Holding Instruments

Tools designed to pick up, hold, or retract tissues and surgical materials.

• Adson Tissue Forceps: Thumb forceps with or without small teeth, used for grasping skin and delicate tissues.
• DeBakey Forceps: Atraumatic, non-toothed forceps used to handle delicate structures (e.g., blood vessels or bowel) without causing damage.
• Allis Clamps: Ratcheted forceps with inward-curving teeth, used for grasping firm tissues like fascia.
• Babcock Clamps: Similar to Allis clamps but with smooth, rounded jaws, designed to hold delicate organs without trauma.
• Sponge Holding Forceps: Ring-handled clamps (like Foerster) used to hold gauze sponges to absorb fluid or prep the surgical site.

3. Clamping and Occluding Instruments

Ratcheted instruments used to control bleeding (hemostasis) or secure tubes. [1]

• Mosquito Hemostats: Small, fine clamps used for precise control of bleeding in shallow wounds.
• Crile Clamps: Larger and slightly stronger than mosquitoes; used for clamping larger vessels.
• Kocher Clamps: Traumatic, toothed clamps used to securely hold tough tissue or clamp heavy, dense structures.
• Towel Clips: Used to fix surgical drapes to the patient’s skin or to secure tubing/cables. [1, 2, 3, 4, 5]

4. Retracting Instruments

Used to hold incisions open or keep organs/tissues out of the surgeon’s field of view. [1, 2]

• Army-Navy Retractors: Handheld, double-ended retractors used in shallow incisions.
• Langenbeck Retractors: Handheld, L-shaped hook retractors for pulling back skin and fatty tissue.
• Richardson Retractors: Handheld, curved-blade retractors used in deep abdominal or chest cavities.
• Weitlaner Retractors: Self-retaining retractors with prongs, commonly used in orthopedic or spinal surgeries.

5. Suturing and Stapling Instruments

Used to hold suture needles and close wounds.

• Needle Holders: (e.g., Mayo-Hegar, Castroviejo) Instruments with textured jaws designed to securely grip and maneuver surgical needles during wound closure.

6. Suction Instruments

Used to remove fluids, blood, and smoke from the surgical field to maintain clear visibility.

• Frazier Suction Tip: An angled, narrow tube with a thumb-hole for precise suction, often used in neurosurgery or ENT.
• Yankauer Suction Tip: A robust, rigid plastic or metal tube used for removing large volumes of fluid.
