What is the name of a surgical knife used in operations?

The name of a surgical knife used in operations is referred to as a scalpel. A scalpel is specifically designed for making incisions in skin and other tissues, making it a crucial tool in surgical procedures. It is typically characterized by its sharp, thin blade that allows for precision in cutting, which is essential for minimizing damage to surrounding tissues.

While the other choices represent surgical tools, they serve different functions. Surgical scissors are used for cutting tissues and sutures, forceps are used for grasping or holding tissues and materials during surgery, and a scalpel blade refers specifically to the blade portion of the scalpel, not the complete instrument. Hence, the scalpel is the correct and complete term for the surgical knife utilized in operations.
