What is indicated by a gold color on the handle of a surgical instrument?

• A. It is made of a precious metal
• B. It contains tungsten carbide
• C. It is a sign of counterfeit instruments
• D. It is a feature of disposable instruments

Answer: (B)

The gold color on the handle of a surgical instrument is indicative of tungsten carbide. This material is commonly used in high-quality surgical instruments due to its exceptional hardness and durability. The gold color often signifies areas of the instrument that have been coated with tungsten carbide to enhance its performance and longevity. This coating helps maintain a sharp edge and reduces wear during surgical procedures.

Tungsten carbide is particularly favored in surgical instruments because it provides improved resistance to corrosion and ensures that the instrument can withstand the rigors of repeated sterilization processes. This feature is crucial in maintaining instrument integrity over time, leading to improved surgical outcomes.

The other options present misunderstanding regarding the purpose and significance of the gold coloration on surgical instruments. In this context, only the presence of tungsten carbide accurately explains the significance of that coloration on instrument handles.
