Surgical Manual Plaster Cutter

DESCRIPTION

A Surgical Manual Plaster Cutter (often called an Engel or Stille Plaster Shear) is a non-powered, hand-operated orthopedic instrument designed to cut through plaster of Paris or synthetic fiberglass casts.

Unlike electric oscillating saws, these tools rely on mechanical leverage, making them indispensable in settings where power is unavailable or when a silent, heat-free removal is preferred.

Key Features & Anatomy

• High-Leverage Handles: Long, ergonomic handles designed to multiply the force applied by the hand, allowing the clinician to cut through thick casting material with minimal effort.

• Specialized Blades:

  • Lower Blade: Features a flat, rounded, or “duck-billed” tip that slides safely between the patient’s skin and the cast to prevent lacerations.

  • Upper Blade: A sharp, often serrated cutting edge that shears through the material against the lower jaw.

• Material: Typically forged from high-grade stainless steel to ensure durability, corrosion resistance, and the ability to withstand repeated sterilization (autoclaving).

• Spring Action: Many models include a leaf spring between the handles to automatically reopen the jaws, reducing hand fatigue during long procedures.

  Advantages vs. Electric Saws

  • Silent Operation: Ideal for pediatric or anxious patients who may be frightened by the loud noise of an electric oscillating saw.

  • No Heat Generation: Eliminates the risk of “friction burns” that can occasionally occur with high-speed electric blades.

  • Portability: Requires no batteries or wall outlets, making it a staple for emergency kits, field hospitals, or home visits.

  • Precision: Provides a tactile feel, giving the surgeon more control when making small adjustments or “windowing” a cast.

  Safety & Maintenance

  While the lower blade is designed to protect the skin, practitioners must still use a “gliding” motion rather than a “pinching” motion to ensure the guard stays parallel to the limb. Post-procedure, it is vital to clean any plaster dust from the pivot screw to maintain smooth mechanical action.
