Surgical blades, also known as scalpels, are essential tools used during surgical procedures to cut through skin and tissue. They come in various types, each designed for specific procedures. The size and shape of the blades are indicated by numbers, which determine their characteristics. Surgical blades are typically made from stainless steel or carbon steel, ensuring durability and effectiveness.

There are different forms of surgical blades available to cater to the needs of surgeons and medical staff. They are usually sold separately from the blade handle. Disposable scalpels, both sterile and non-sterile, consist of a plastic handle connected to a surgical blade. Safety scalpels have a protective cover that keeps the blade covered until it is ready to be used, reducing the risk of accidental contact.

Some commonly used surgical blades include the number 10, which has a large curved cutting edge for making incisions and cutting soft tissue. The number 11 is elongated and triangular, ideal for precise cuts in shallow recessed areas. The number 12 is a small, pointed crescent-shaped blade, often used as a suture cutter. The number 15 has a small, curved cutting edge for precise incisions, while the number 22 is larger and used for creating incisions through thick skin.

The edge, spine, and slot are distinguishing features of surgical blades. The edge refers to the sharp cutting surface, the spine is the unsharpened rigid edge, and the slot allows the blade to securely lock onto the handle.

The most common type of surgical blade used in surgery is the non-attached, replaceable blade, which can be easily locked onto the handle. This allows for convenience and flexibility during procedures. Surgical blades play a crucial role in ensuring precise and efficient surgical techniques.
