Surgical instruments have a long history, but their modern versions have only been around for a relatively short period of time. Available in different shapes and sizes for diverse surgeries, contemporary scalpel blades and handles are typically crafted from hardened and tempered steel, stainless steel, and high carbon steel, with blade shapes designed according to their intended use. Recognized as indispensable surgical tools, scalpel blades contribute to precise incisions and minimal scarring, which is particularly crucial in minimally invasive, ophthalmic, cardiovascular, and endoscopic surgeries. Cutting in a firm and controlled way, usually at angles of 30–90 degrees from the tissues, necessitates holding the instrument in various ways, often placing a steadying forefinger along the back of the instrument. The tissue through which the scalpel is incising should also be steadied and put under a slight degree of tension.
The demonstration of surgical scalpels in this video provides valuable insights into their usage. The handles are available in different designs, serving two functions: fitting the appropriate size of surgical blades and ensuring a firm hold to reduce the chance of slipping.
Surgical blades come in sterile packaging, and the number on a surgical blade communicates both its size and shape. This video demonstration aids in understanding how each blade is tailored to meet certain demands in surgery.
