Surgical blades, or scalpels, are used for cutting skin and tissue during surgical procedures. There are different types of blades specific to the type of procedure. Surgical blades vary by size and shape. The number of the blade indicates the blade size and shape. theses numbers are as below:
10, 10A , 11, 11P, 12, 12D, 13, 15, 15SM, 15c, 18, 19, 20, 21, 22, 22A, 23, 24, 25, 26 & 36
Surgical blades are typically made with stainless steel or carbon steel.
Common Surgical Blade Sizes:
Surgical blades come in a variety of forms giving surgeons and medical staff the right blade for the procedure. Surgical blades are typically sold separate from the blade handle. Surgical blades are available in disposable scalpels (sterile and non-sterile). Disposable scalpels are single-use scalpels that commonly use a plastic handle connected to a surgical blade. Safety scalpels are scalpels that have a covering around the blade that covers the blade until it is used. Safety scalpels help prevent accidental contact with the surgical blade.
Some of the most common blades are described below:
- The number 10 blade has a large curved cutting edge is one of the more traditional blade shapes and is used for making large incisions and cutting soft tissue.
- The number 11 blade is an elongated, triangular blade sharpened along the hypotenuse edge. It has a pointed tip making it ideal for stab incisions and precise short cuts in shallow recessed areas.
- The number 12 blade is a small, pointed crescent-shaped blade sharpened along the inside edge of the curve. It sometimes used as a suture cutter.
- The number 15 blade has a small, curved cutting edge ideal for making short, precise incisions.
- The number 22 blade is a larger version of the number 10 blade with a curved cutting edge and a flat, unsharpened back edge. It is often used for creating large incisions through thick skin.
