A surgical blade is also known as the scalpel is an important tool for performing surgical procedures and tissue dissections. They differ in sizes and shapes. They have different numbers which indicate their size and shape. The differentiating factor of surgical blades is the spine, slot, and edge.
The surgical blades or scalpels can be single-use disposable or re-usable. The re-usable scalpel has permanently attached blades which can be re-used and also be sharpened. The disposable scalpels usually come with a plastic handle and an extensible knife and can be used only once.
During surgery, the non-attached and replaceable blade is the most commonly used scalpel blade.
