Stainless Steel
An alloy of steel with chromium 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 shape bone
Rongeurs
Surgical instruments used to cut or bite away at bone and tissue.
Forceps
Instruments used for grasping, holding firmly, or exerting traction upon objects
Hemostatic forceps
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)
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 through their center. They are more often inserted for drainage.
Suction devices
Surgical instruments used to extract blood and other fluids from surgical site.
Austenitic ( Stainless steel)
300 series stainless steel. It is non-magnetic, cannot be heat-hardened, and is more corrosion resistant than 400 series
Serrations
Parallel grooves in the jaws of surgical instruments
Passivation
A chemical process applied during the instrument manufacturing process that provides a corrosion-resistant finish by forming a thin, transparent oxide film.
Box Lock
Point where the two jaws or blades of an instrument connect and pivot.
Jaws
Two or more opposable parts that open and close; used for holding or crushing something between them.
Dissection
The process of cutting apart or separating tissue.
What is the primary funtion of a rongeur?
A rongeur is used to cut or bite away at bone and tissue
What is the primary funtion of Kerrison rongeur?
The Kerrison rongeur is used to remove the disc or lamina during spine surgery.
What is the appropriate medium to test the sharpness of an osteome?
To test the sharpness of an osteotome is to shave off a plastic dowel rod.
How many times should tape be wrapped around an instrument for identification purposes?
Tape should be wrapped 1 1/2 times around the tool.
Where should that tape be placed?
The tape should be placed on the shank.
What is the purpose of a stringer?
Stringers hold instruments in the open position during sterilization. They can assist in faster sterile field assembly and safer handling of the instruments.
Where are heavy instruments placed in relationship to light instruments?
Heavy instruments must be placed on the bottom or side of the tray.
