Phenolic material is primarily used in which part of surgical instruments?

• A. The blades
• B. The handles
• C. The tips
• D. The joint areas

Answer: (B)

Phenolic material, a type of thermosetting plastic, is commonly utilized in the handles of surgical instruments due to its advantageous properties. Handles require a material that provides a firm grip, resistance to moisture, and can withstand repeated sterilization processes without degrading or losing structural integrity. Phenolic resin has excellent mechanical strength and is not only durable but also resistant to heat and various chemicals, making it ideal for the demands of a surgical environment. This combination of characteristics ensures that surgical instruments are comfortable for long-term use while maintaining safety and effectiveness during procedures.

Other components of surgical instruments like blades, tips, and joint areas typically require metals or alloys for their strength and precision rather than plastics. These areas are critical for the instrument's functionality and performance, which is why they are made from materials with specific properties suited to cutting or connecting actions.
