Which knife handle is used to hold blades like 10, 11, 12, and 15?

The No. 3 knife handle is specifically designed to accommodate a variety of blades, including the commonly used 10, 11, 12, and 15 blades. Each of these blades serves different purposes depending on the surgical procedure. The No. 3 handle provides a secure grip and a proper alignment for these blades, allowing for precise incisions and effective surgical performance. The ergonomic design of the handle helps surgeons and surgical technologists maintain control during procedures, contributing to the overall safety and success of the surgery.

In contrast, the other options do not serve this purpose, as they include either incorrect handles or unrelated surgical instruments. For instance, the No. 4 handle is larger and intended for larger blades that are typically used for more extensive surgeries. The No. 10 blade refers to a specific type of blade and not a handle, while straight mayo scissors are designed for cutting tissues and do not hold blades at all. Understanding the correct handle to use with specific blades is essential in surgical practice, ensuring that the right tools are available for the task at hand.
