Surgical Instruments and Inspection Master Sheet

Vocabulary flashcards covering surgical instrument anatomy, functional categories, metallurgy, inspection standards, and maintenance based on CBSPD exam objectives.

Box Lock

The hinge pin or joint of a ring-handled instrument; it is the most critical site for cracks and organic debris and is considered the weakest part of the instrument.

Jaws

The working surface of an instrument that may feature teeth, serrations (transverse, longitudinal, or cross-hatched), or tungsten carbide inserts.

Ratchet

Interlocking teeth on ring-handled instruments that allow the device to be locked closed at varied levels of tension.

Metzenbaum Scissors

Delicate scissors used specifically for tissue dissection.

Mayo Scissors

Heavy-duty scissors used for cutting sutures or heavy tissue.

Hemostats

A category of clamping/occluding instruments, such as Crile, Kelly, or Mosquito, used to compress blood vessels to stop fluid flow.

Allis Clamp

A grasping/holding instrument featuring sharp teeth used to grip tissue.

Babcock Clamp

An atraumatic grasping/holding instrument with smooth surfaces used for delicate structures like the bowel.

Self-Retaining Retractors

Instruments such as the Weitlaner or Gelpi that stay open on their own via a ratchet mechanism to expose the surgical site.

Poole Suction

An instrument used for abdominal suction that features a perforated outer sheath.

Frazier Suction

A fine suction tip used in neurosurgery or orthopedics that includes a stylet to clear any internal clogs.

Martensitic Stainless Steel (400 Series)

A hard, strong, and magnetic alloy that is heat-treated for edge retention; used for cutting edges and locking mechanisms.

Austenitic Stainless Steel (300 Series)

A malleable, non-magnetic metal that is highly resistant to corrosion; used for retractors, suction tubes, and trays.

Ebony Finish

A black, non-reflective anodized finish that absorbs laser energy to prevent light from bouncing into non-target tissues during laser procedures.

Tungsten Carbide Inserts

Super-hard metal components found in gold-handled instruments that allow jaws and edges to last 5 times longer than standard steel.

Passivation

A manufacturing process involving a chemical bath (nitric or citric acid) that removes free iron and forms a protective microscopic Chromium Oxide layer on an instrument.

Pitting

Severe localized corrosion caused by exposing stainless steel to saline, blood, bleach, or harsh chemicals.

Rust

True corrosion that eats into the metal and cannot be wiped off; instruments with this condition must be removed from service immediately to prevent spreading to other tools.

Ratchet Test

An inspection step where the instrument is closed on the first tooth and tapped against a surface; if it pops open, it fails and requires repair.

Surgical Milk

A water-soluble, non-silicone instrument lubricant applied after washing and before sterilization to prevent corrosion and keep parts moving freely.
