When it comes to surgeries involving skin or tissue cutting, surgical blades are the tools that come to mind for their precision and durability. These blades are often made from stainless steel, carbon steel, or high‑carbon steel, materials selected for their hardness, durability, and capacity to maintain a very sharp cutting edge. The surgical blades are available in multiple sizes, both reusable and disposable. In this blog, we will discuss the different types of surgical blades, their uses, and how to make the right choice.
What are Surgical Blades?
Surgical blades are essential, detachable cutting instruments that easily fit into the surgical scalpel handle for use on deep and superficial surfaces. They are disposable, single-use items, supplied in sterile, individually wrapped packaging to guarantee maximum safety and sharpness. The blades come in different variations, indicated by a numerical code stamped on their surface (e.g., #10, #15, #22). The numbers assigned to each surgical blade are not random; they correspond to specific shapes and sizes that dictate the blade's primary function.
- Blades with numbers below 20 (e.g., #10, #15) are generally used with the smaller, more common #3 handle and are suitable for more delicate, precise work.
- Blades numbered 20 and above (e.g., #22, #24) are used with the larger #4 handle and are typically employed for making large incisions in thick tissue.
Common Types of Surgical Blades and Their Uses
The following are the common types of surgical blades, along with their uses, to help you understand the difference between them.
#10 Blade
This is the most classic surgical blade, designed with a curved cutting edge and a rounded point to help make large, shallow incisions in skin and muscle. It is a general-purpose blade often used for initial incisions in general, cardiac, and orthopedic surgery.
#11 Blade
This particular type of surgical blade is triangular, with a long, sharp, pointed tip and a straight cutting edge along the hypotenuse. They are mainly used to make incisions and short, precise cuts in confined or recessed areas, especially when inserting chest drains and making short, linear cuts.
#12 Blade
The blade no. 12 is a small, pointed, crescent-shaped blade with the cutting edge on the inside curve, primarily used for suture removal, especially in dental or ear, nose, and throat (ENT) surgery.
#15 Blade
This blade is very similar to the #10 blade but is significantly smaller and more curved, for making small, curved incisions and dissecting superficial tissue. It is primarily used in plastic surgery, hand surgery, and podiatry, as well as for excising small skin lesions.
Larger Blades (#20, #21, #22, #23, #24, #25 …)
These surgical blades are comparatively larger versions of the #10, #11, and #15 designs, but are designed to fit the #4 handle. The blades #20 and #22 are the original, larger version of the #10 blade used for long, deep incisions through thick or tough tissue. On the other hand, the #23 blade has a leaf-shaped cutting edge, which is ideal for making long incisions in delicate tissue.
How Surgeons Choose the Right Blade
The following are several factors for which the selection of a specific blade is a crucial part of pre-operative planning.
- The type of procedure determines the necessary cut; for example, a cardiac bypass requires large incisions, while an eye procedure demands micro-scalpels.
- The density, size, and thickness of the tissue being cut determine the appropriate blade.
- The type of incision is also considered, whether it should be long and straight or highly curved.
- The depth and confinement of the surgical site influence the choice of the surgical blade.
