Metal Terminology
What is an extremely hard metal used in the jaws of needle holders, forceps, and pin cutters, blades of scissors, and bone files.
When tungsten carbide is present, the handle of the instrument is gold in color.
Tungsten Carbide
Titanium Nitride
Titanium
Stainless Steel
The portion of the surgical instrument that is closest to the user.
For example, the distal tip of a tissue forceps is the teeth.
Distal
Proximal
What is the selective removal of iron from stainless steel surfaces using a nitric acid bath.
This process forms a protective layer to help prevent corrosion of the metal.
Rockwell Scale
Cavitation
Passivation
LEEP Coating
What is the brown/orange/red discoloration on an instrument that can be removed using the pencil eraser test.
Rusting
Staining
What is the stainless steel that cannot be heat-hardened.
Stainless steel that falls into this category is 300 series stainless steel, which is highly
Titanium
Austenitic
Aluminum
Martensitic
What is the black coating applied to a surgical instrument that minimizes glare during the surgical procedure.
It also makes the instrument harder and more corrosion resistant.
Diamond Dust
Ceramic
Heat Fused Nylon
LEEP Coatings
What is the most commonly used metal in the manufacturing of surgical instruments.
Stainless steel may stain and/ or rust.
Stainless Steel
Sterling Silver
Titanium
Aluminum
What is the coating used in the jaws of needle holders and forceps used in delicate surgeries such as cardiovascular procedures.
No diamonds are present; rather, the jaws have tungsten carbide particles to grip very fine needles.
Titanium Nitride
Diamond Dust
Phenolic
Tungsten Carbide
What is the high-frequency pressure (sound) waves used in ultrasonic machines to form bubbles that implode on surgical instruments.
This formation of bubbles pulls the blood and mucus off the instrument.
Martensitic
Cavitation
Phenolic
Passivation
A removable part of the surgical instrument used during insertion of the instrument into the patient.
A common example is the obturator of a resectoscope sheath.

Dowel Rod
Stylet
