A surgical instrument is a specially designed tool or device for performing specific actions of carrying out desired effects during a surgery or operation. Along time, many different kinds of surgical instruments and tools have been invented, some of them of a more general character, others designed for a specific type of surgery. Accordingly, the nomenclature of surgical instruments follows certain patterns, such as a description of the action it performs (for example, scalpel, curette), the name of its inventor(s) (for example, the Kocher forceps), or a compound scientific name related to the kind of surgery (for example, tonsillotome).
