Scalpel

Various scalpels

Scalpel is a small and extremely sharp bladed instrument used for surgery, anatomical dissection, and various arts and crafts (called a hobby knife). Scalpels may be single-use disposable or re-usable. Re-usable scalpels can have permanently attached blades that can be sharpened or, more commonly, removable single-use blades. Disposable scalpels usually have a plastic handle with an extensible blade (like a utility knife) and are used once, then the entire instrument is discarded. Scalpel blades are usually individually packed in sterile pouches but are also offered non-sterile.

History

The earliest known scalpels were made of flint or obsidian during the Stone Age. In the Bronze Age and the Iron Age, scalpels were made of bronze and iron respectively. The Greeks and the Romans made scalpels of steel. The scalpel itself did not change significantly over time, but the materials used to make it did.

Types of Scalpels

There are two types of scalpels: disposable and re-usable. Disposable scalpels are used once and then discarded. They usually have a plastic handle and an extensible blade. Re-usable scalpels can have permanently attached blades that can be sharpened, or removable single-use blades.

Uses

Scalpels are used in surgery for making incisions. They are also used in anatomical dissection and various arts and crafts.

Safety

Scalpels are extremely sharp and must be handled with care. They should be kept out of reach of children and pets. When not in use, the blade should be covered or retracted to prevent accidental cuts.
