What Are Surgical Scissors?

Surgical scissors are specialized instruments used to cut tissue, sutures, bandages, and other materials during surgical procedures. Unlike ordinary scissors, surgical scissors are engineered for high precision, minimal tissue damage, and long-term durability under sterilization and repeated use.

They typically consist of:

• Two sharp blades connected at a pivot.

• Finger rings or loops for manual operation.

• Varied blade shapes (straight, curved, blunt, or pointed).

Each surgical scissor is carefully crafted for specific medical applications—from deep tissue dissection to surface-level bandage cutting. The quality and functionality of surgical scissors directly impact the outcome of a procedure, making their design and use critical to medical practice.

History and Evolution of Surgical Scissors

The use of cutting instruments in medicine dates back to ancient Egypt, where bronze and iron tools were used for basic surgeries. However, modern surgical scissors began to evolve in the 19th century alongside advancements in surgical techniques and sterilization practices.

With the invention of stainless steel in the early 1900s, scissors could now withstand high temperatures during autoclaving. As surgery became more specialized, so did the instruments. Manufacturers began producing scissors with specific designs tailored for delicate tissues, hard structures, or deep surgical fields.

In recent decades, further innovation has introduced titanium blades, tungsten carbide inserts, and even robotic surgical scissors controlled via AI-assisted systems, marking a dramatic evolution from their humble origins.

Key Features of Surgical Scissors

A good pair of surgical scissors combines sharpness, precision, control, and durability. Here are the key components that define a high-quality surgical scissor:

1. Blade Type

• Straight Blades – Ideal for surface-level cutting and suture removal.

• Curved Blades – Used for cutting deeper tissues while maintaining visibility.

• Blunt Tips – Prevent accidental punctures; good for safe dissection.

• Sharp Tips – Offer better access in confined or tough tissues.

2. Handle Design

Most surgical scissors come with ring handles, but ergonomic designs with soft-grip coatings are now available for comfort and prolonged use.

3. Blade Edge

• Plain Edge – Smooth and ideal for soft tissue cutting.

• Serrated Edge – Offers grip and reduces slippage, often used in orthopedic procedures.

4. Material Composition

High-quality surgical scissors are made from:

• Surgical-grade stainless steel

• Tungsten carbide inserts for added hardness

• Titanium for lightweight and anti-magnetic properties

• Use: Cutting heavy tissues like fascia, muscles

• Material: Strong stainless steel for durability

2. Metzenbaum Scissors

• Blades: Longer, thinner, curved

• Use: Cutting delicate tissue

• Popular in: Abdominal and cardiovascular surgeries

3. Iris Scissors

• Blades: Fine, small, and very sharp

• Use: Eye surgeries, microdissections

• Known for: Extreme precision

4. Operating Scissors

• Blades: Can be sharp/sharp, blunt/blunt, or sharp/blunt

• Use: General-purpose cutting of tissue or sutures

5. Suture Scissors

• Feature: Hooked tip for lifting sutures

• Use: Cutting and removing stitches

6. Bandage Scissors (Lister)

• Blade: Angled lower blade with blunt tip

• Use: Cutting dressings and bandages safely

7. Potts-Smith Scissors

• Blades: Angled and very fine

• Use: Vascular surgeries

8. Tenotomy Scissors

• Blades: Extremely delicate and short

• Use: Precise cutting of small, soft tissue structures

Each type serves a unique surgical role, and a single procedure may require several types depending on its complexity.

Applications of Surgical Scissors Across Medical Fields

Surgical scissors are used in virtually all medical disciplines. Here’s how they are applied:

1. General Surgery

• Cutting muscle, tissue, or sutures

• Dissecting deeper layers of skin or fascia

2. Orthopedics

• Serrated scissors are used to handle dense, fibrous tissue

• Cutting tendon sheaths and ligaments

3. Cardiothoracic Surgery

• Fine scissors like Potts-Smith are used for vessels and valves

4. Gynecology

• Curved scissors are used for uterine and pelvic tissue dissection

5. Ophthalmology

• Iris scissors are used for ultra-fine procedures like corneal repair

6. Neurosurgery

• Micro scissors for brain and spinal cord tissue

7. Emergency Rooms

• Bandage scissors for quick access

• Multipurpose operating scissors for trauma wounds

No matter the specialty, surgical scissors provide the accuracy and speed needed for effective surgical interventions.

Handling Techniques and Best Practices

Proper handling ensures better results and safety. Here are some techniques:

• Always grip scissors with the thumb and ring finger for control.

• Use the index finger along the shaft to stabilize.

• Select the right blade type based on tissue depth and density.

• Apply gentle pressure; forcing cuts can damage tissue and dull blades.

• Avoid using surgical scissors on non-biological materials, which can dull or damage the blade edge.

Training and practice are essential. Surgeons spend years perfecting their scissor-handling technique to ensure smooth, efficient, and safe tissue manipulation.

Sterilization and Maintenance

To maintain performance and prevent cross-contamination, proper care is essential:

Cleaning

• Rinse immediately after use.

• Use neutral pH enzymatic cleaners to avoid corrosion.

Inspection

• Check for alignment, dullness, or loosened pivot joints.

Sharpening

• Professional sharpening prolongs scissor life.

• Tungsten carbide blades require special sharpening tools.

Sterilization

• Autoclave under standard surgical instrument protocols.

• Avoid overexposure to steam to preserve blade integrity.

Storage

• Store in dry, sterile trays, avoiding blade-on-blade contact.

• Use individual pouches or compartments for high-end or fine scissors.

With proper care, high-quality scissors can remain functional and precise for 10 years or more.
