Can tungsten carbide scissor blades be replaced?

• A. Yes, they can be replaced
• B. No, they cannot be replaced
• C. Only if damaged
• D. Only in special circumstances

Answer: (B)

Tungsten carbide scissor blades are known for their exceptional hardness and durability, which makes them ideal for surgical instruments. However, once the blades are manufactured and attached to the scissors, they are typically not designed for replacement. This is primarily due to the complex manufacturing processes and the precise alignment required for optimal functionality.

In surgical settings, maintaining the integrity and performance of these instruments is crucial for patient safety and effective procedures. Even if they become dull over time, rather than replacing the blades, these instruments are usually sharpened or serviced by specialized professionals to restore their cutting efficiency. Thus, replacing tungsten carbide scissor blades is generally not an option, reinforcing that they cannot be replaced through standard processes. This is the reason why the statement that they cannot be replaced is accurate.
