Surgical Knife

A surgical knife, also known as a scalpel, is a specialized type of knife used in surgery and other medical procedures. The term "scalpel" is derived from the Latin word "scallpellus," which means "small knife."

History[edit | edit source]

The use of surgical knives dates back to the Stone Age, when sharp-edged tools were used for medical procedures. The design and materials used in surgical knives have evolved over centuries, with modern surgical knives being made of stainless steel or high-grade carbon steel.

Design[edit | edit source]

A surgical knife typically consists of two parts: the blade and the handle. The blade is usually disposable and can be replaced after each use to maintain sterility. The handle is designed to provide a firm grip and precise control during surgery.

Types[edit | edit source]

There are several types of surgical knives, each designed for specific surgical procedures. These include:

Bistoury knife: A long, narrow knife used for cutting deep, narrow passages.
Lancet: A small, wide knife used for making small incisions.
Liston's knife: A large, straight knife used for amputations and major surgical procedures.
Metzenbaum scissors: A type of surgical scissors used for cutting delicate tissues.

Usage[edit | edit source]

Surgical knives are used in a variety of medical procedures, including surgery, autopsy, and biopsy. They are also used in dissection in anatomical studies.

Safety and Sterilization[edit | edit source]

Safety and sterilization are critical aspects of surgical knife usage. The blades are typically single-use to prevent cross-contamination. They are disposed of in designated sharps containers to prevent accidental injuries. The handles are sterilized before each use using methods such as autoclaving or chemical sterilants.
