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

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

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

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

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

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.
