The scalpel handle holds a scalpel blade to facilitate use during Surgery. Some plastic handles with a blade already attached are disposable and intended for single procedure use on just one patient. Metal scalpel handles are sterilized in the autoclave for reuse in multiple Surgical cases. A fresh blade slots onto the scalpel handle and can be replaced as needed during Surgery by the Surgical Technologist or Scrub Nurse. Scalpel blades are intended for limited use to make sure that a sharp blade is always available for precision work. Different types and sizes of blade can be fitted to suite the Surgeons needs.
