B) To prevent needle rusting
C) To provide a non-slip grip
D) To increase the overall weight of the holder
E) To enhance needle sharpness

Answer 1

Tungsten carbide inserts on needle holders are utilized to provide a non-slip grip, ensuring the needle is held securely during surgical procedures for precision and safety.

Step-by-step explanation:

The purpose of a tungsten carbide insert on a needle holder is to provide a non-slip grip. This hard material ensures that the needle is held firmly and prevents it from rotating or slipping while suturing tissues, which is essential for precision and safety during surgical procedures. The use of tungsten carbide is particularly useful for microsurgical instruments where utmost precision is required.

The purpose of a tungsten carbide insert on a needle holder is to enhance needle sharpness. Tungsten carbide is a hard and durable material that can be used to coat the tips or edges of instruments, including needle holders. The sharpness of the tungsten carbide insert allows for more precise and controlled needle placement during medical procedures, reducing the risk of tissue damage.
