Surgical Instrumentation
Stainless steel
An alloy of steel with chromium and sometimes another element, such as nickel or molybdenum, that is highly resistant to rusting and ordinary corrosion.
Scissors
Surgical instruments used to cut, incise and/or dissect tissue.
Osteotomes
Chisel-like instruments used to cut or shave bone.
Chisels
Wedge-shaped instruments used to cut or shape bone.
Rongeurs
Surgical instruments used to cut or bite away bone and tissue.
Forceps
Instruments used for grasping, holding firmly or exerting traction upon objects.
Homeostatic forsceps
Surgical instruments used to control the flow of blood.
Needle holders
Surgical instruments designed to drive suture needles to close or rejoin a wound or surgical site. Also known as needle drivers.
Martensitic stainless steel
This metal is also known as 400 series stainless steel. It is magnetic and may be heat-hardened.
Retractors
Surgical instruments primarily used to move tissues and organs to keep the surgical site exposed throughout surgery.
Cannulas
Surgical instruments with a hollow barrel (or lumen) through their center. Cannulas are often inserted for drainage.
Rib spreaders
A retractor used to expose the chest.
Suction devices
Surgical instruments used to extract blood and other fluids from a surgical site.
Austenitic stainless steel
Also know as 300 series stainless steel. It is non-magnetic, cannot be heat-hardened and is more corrosion resistant than martensitic stainless steel.
Passivation
A chemical process applied during instrument manufacturing that provides a corrosion-resistant finish by forming a thin transparent oxide film.
