DERMATOME

Dermatome in Plastic Surgery – Detailed Specifications

A dermatome is a specialized surgical instrument used in plastic surgery to harvest thin, uniform layers of skin for grafting procedures. It is essential in treating burns, trauma injuries and reconstructive surgeries.

Types of Dermatomes

1. Air-Powered (Pneumatic) Dermatome:

   • Operates using compressed air for precision.
   • Preferred for large-area skin grafts due to consistent cutting depth and speed.

2. Electric Dermatome:

   • Powered by electricity for continuous, smooth operation.
   • Offers precise depth control for uniform skin graft thickness.

3. Manual (Drum) Dermatome:

   • Operated manually with a handle and roller.
   • Suitable for small or localized skin grafts.

Key Specifications and Features

1. Cutting Depth Control

• Adjustable depth settings, typically ranging from 0.1 mm to 1.0 mm for precise graft thickness.
• Fine-tuned controls for enhanced accuracy in delicate procedures.

2. Blade Specifications

• Material: Surgical-grade stainless steel for sharpness and durability.
• Size Options: Blades vary in width from 25 mm to 100 mm for different graft sizes.
• Designed for easy replacement to maintain precision.

3. Power Source (for Electric and Pneumatic Models)

• Electric Models: Operate at 110V/220V AC with adjustable speed controls.
• Pneumatic Models: Require air pressure levels around 90-100 psi for stable performance.

4. Handle and Ergonomics

• Lightweight design with ergonomic grips for surgeon's comfort.
• Balanced weight distribution for better control during procedures.

5. Skin Tensioning Mechanism

• Ensures uniform stretching of the skin to achieve even graft thickness.
• Reduces the risk of irregular cuts or skin damage.

6. Safety Features

• Protective Guards: Prevents accidental deep cuts.
• Auto Shut-off (in electric models): Ensures safety in case of overheating or malfunctions.

7. Sterilization and Maintenance

• Constructed with materials compatible with autoclave sterilization.
• Detachable components for easy cleaning and maintenance.

Recommended Accessories

• Sterile Blades: For single-use applications to maintain hygiene.
• Graft Carriers: To secure and transfer harvested skin safely.
• Measuring Guides: To ensure uniform skin thickness.

Applications in Plastic Surgery

• Burn Treatment: Harvesting skin grafts to cover damaged tissue.
• Scar Revision: Removing thickened or damaged skin layers.
• Reconstructive Surgery: Skin grafting for trauma injuries, chronic ulcers or deformity corrections.

Conclusion

Dermatomes play a crucial role in plastic surgery, offering precision, efficiency and consistency in skin graft harvesting. Selecting the appropriate dermatome model—manual, electric or pneumatic—depends on the procedure type, desired graft thickness and surgical complexity. Modern dermatomes with advanced depth control and ergonomic designs enhance surgical outcomes while ensuring patient safety.
