Surgical Instrumentation

Stainless Steel

• An alloy of steel with chromium and sometimes another element,

• such as nickel or molybdenum,

• highly resistant to rusting and ordinary corrosion.

Scissors

Surgical instruments used to

cut

incise

dissect tissue

Osteotomes

Chisel-like instruments used to

cut or shave bones

Chisel

Wedge-shaped instruments

used to cut or shave bone

Ronguers

Surgical instruments used to

cut or bite away at bone and tissues

Forceps

Instruments used for

-grasping,

-holding firmly

-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.

Mart-en-sit-ic Stainless Steel

This metal is also known as 400 series stainless steel.

magnetic and may be heat-hardened.

Retractors

Surgical instruments primarily used to

move tissues and organs

keep the surgical site exposed throughout surgery

Cannulas

Surgical instruments with a hollow barrel (or lumen) through their center.

-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.

Aus-ten-tit-ic stainless steel

Also known as 300 series stainless steel.

non-magnetic,

cannot be heat-hardened 

more corrosion-resistant than martensitic stainless steel. 

Serrations

Parallel grooves in the jaws of surgical instruments.

Rachets

The part of a surgical instrument that locks the handles in place.

Passivation

A chemical process applied during instrument manufacturing 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.
