What are 2 different types of surgical blades?

Surgical blades play a crucial role in diverse surgical procedures. They come in a multitude of shapes and sizes, meticulously crafted to serve specific purposes with utmost precision. Two of the most common types of surgical blades are scalpel blades and lancets.

Scalpel blades are typically used to make larger incisions and dissections. These blades come in various shapes, such as straight, curved, and triangular, offering a diverse range of options to choose from. Scalpel blades are also available in different sizes, with each size numbered according to its width. Some of the most common scalpel blade numbers include:

  • No. 10: Curved blade used for making general incisions
  • No. 11: Triangular blade used for making precise incisions
  • No. 15: Bard-Parker blade, a versatile blade used for a variety of procedures

Lancets are small, sharp blades used to make smaller incisions, such as those made to draw blood or perform a biopsy. Lancets are typically single-use and are available in a variety of sizes.

Scalpel blades as well as lancets are commonly crafted from stainless steel, carbon steel, or ceramic materials. Stainless steel is the most common material used for surgical blades, as it is durable and resistant to corrosion. While carbon steel blades offer superior sharpness compared to their stainless steel counterparts, they do come with the drawback of being more susceptible to rusting. Ceramic blades are the sharpest type of surgical blade, but they are also the most expensive and fragile.

The selection of a surgical blade for a particular procedure hinges upon the individual requirements of the surgeon. Careful consideration must be given to ensure the best match between blade type and surgical needs. For example, a surgeon performing a complex cardiac surgery will need to use a variety of different scalpel blades to make precise incisions and dissections. A surgeon performing a simple blood draw will only need to use a small lancet.
