Various scalpels A<unk>  is a tool or device for performing specific actions or carrying out desired effects during a surgery or operation, such as modifying biological tissue, or to provide access for viewing it. Over time, many different kinds of<unk> s and tools have been invented. Some<unk> s are designed for general use in all sorts of surgeries, while others are designed for only certain specialties or specific procedures. Accordingly, the nomenclature of<unk> s follows certain patterns, such as a description of the action it performs (for example, scalpel, hemostat), the name of its inventor(s) (for example, the Kocher forceps), or a compound scientific name related to the kind of surgery (for example, a tracheotome is a tool used to perform a tracheotomy). The expression<unk> ation is somewhat interchangeably used with<unk> s, but its meaning in medical jargon is the activity of providing assistance to a surgeon with the proper handling of<unk> s during an operation, by a specialized professional, usually a<unk>  technologist or sometimes a nurse or radiographer.
