Surgical Instrumentation: An Interactive Approach Vocabulary Flashcards

A collection of vocabulary flashcards covering surgical instrument categories, specific biological naming conventions, and fundamental tools used in various surgical procedures as described in Renee Nemitz's 'Surgical Instrumentation'.

Surgical Instrument

A specially designed device or apparatus used to carry out a specified task during a surgical procedure.

Stainless Steel

A combination of carbon, chromium, iron, and other metals (alloys) that makes instruments strong and resistant to wear and corrosion.

Mirror Finish

A highly polished finish on stainless steel that reflects light and causes glare but is highly resistant to corrosion.

Satin or Matte Finish

A dull finish on stainless steel that reduces glare and is the preferred finish for surgical instruments.

Ebony Finish

A black chromium finish that eliminates reflection and glare; used during laser procedures to prevent light beam deflection.

Gold Plating

Signifies that tungsten carbide was incorporated into the manufacturing process to increase sharpness in scissors or strength in needle holder jaws.

Joint

The area where two halves of a ringed instrument are joined to permit opening and closing; typically a box lock or a screw joint.

Jaws

The working portion of the instrument beyond the joint, whose inner shape and tips determine how it is used on tissues.

Accessory Category

Instruments that do not fall into other categories but have specific functions, such as a mallet, screwdriver, or harmonic scalpel.

Clamping and Occluding

Instruments used to compress vessels and tubular structures to impede or obstruct the flow of blood and other fluids.

Cutting and Dissecting

Instruments with razor-sharp edges or blades, such as scalpels and scissors, used to incise, dissect, and excise tissues.

Grasping and Holding

Instruments designed to grip and manipulate body tissues, often used to stabilize tissue during excision or repair.

Probing and Dilating

Blunt, malleable instruments used to explore structures or gradually enlarge orifices and tubular structures.

Retracting and Exposing

Instruments designed to hold back wound edges, organs, or tissues to gain access to the clinical site.

Electrosurgical Pencil (Bovie)

An accessory that uses monopolar current to coagulate and cut tissue to provide homeostasis.

Harmonic Scalpel

An accessory that delivers ultrasonic energy between jaws to coagulate and divide tissue by low-temperature cavitation.

Halstead Forceps (Mosquito)

A small curved or straight clamp with fine tips and horizontal serrations used for occluding bleeders in small or superficial wounds.

Crile Forceps (Hemostat)

A curved or straight clamp with horizontal serrations running the complete length of the jaws; the most widely used clamp in all specialty areas.

Mixter Forceps (Right angle)

A $45^{\circ}$-degree angle clamp used to clamp, dissect, and occlude tissue, often for placing a tie around a tubular structure.

Curved Mayo Scissors

Heavy scissors with curved blades and blunt or sharp tips used to dissect or undermine heavy fibrous tissues.

Lister Bandage Scissors

Angled blunt scissors with a smooth flattened tip on the lower blade to cut dressings and drapes without harming the patient.

$\text{No. } 3$ Knife Handle

A handle that holds blades $"10, 11, 12, \text{ and } 15"$; used to make skin incisions or fine precision cuts.

$\text{No. } 4$ Knife Handle

A handle with a larger tip designed to hold blades $"20, 21, 22, 23, 24, \text{ and } 25"$ for larger or deeper incisions.

DeBakey Tissue Forceps

Atraumatic vascular tissue forceps with parallel fine serrations that interlock to grip securely without causing tissue damage.

Ferris-Smith Tissue Forceps (Big Uglys)

Large forceps with $1 \times 2$ interlocking teeth and crisscrossed pattern serrations used for heavy tissue, muscle, and bone.

Russian Tissue Forceps

Forceps with rounded tips and starburst pattern serrations, commonly used for grasping dense tissues and during wound closure.

Towel Clip (Penetrating)

A ratcheted instrument with curved, sharp, tine-like jaws used for holding towels in place or grasping tough tissue.

Babcock Forceps

An atraumatic forceps with a flared, rounded, hollow end and smooth tips used for grasping delicate structures like ureters and bowel.

Kocher Forceps (Ochsner)

An instrument with horizontal serrations and $1 \times 2$ large interlocking teeth at the tip used for grasping tough, fibrous, slippery tissues.

Senn Retractor

A double-ended handheld retractor with three sharp or dull claws on one end and a small narrow blade on the other.

Weitlaner Retractor

A self-retaining retractor with outward-curved prongs ($3 \times 4$) and a ratchet release device used to hold wound edges open.

Frazier Suction Tip

An angled cylindric tube measuring from $3F$ to $15F$ used for suctioning in confined spaces like the nasal cavity or craniotomies.

Poole Suction Tip

A suction tip with an outer sheath and inner cannula featuring multiple fenestrations to remove large amounts of fluid from body cavities.

Yankauer Suction Tip

A hollow tube with a bulbous tip and large opening used for effective suctioning in all types of wounds without aspiration damage to surrounding tissue.

Ryder Needle Holder

A needle holder with finely tapered jaws and carbide inserts, often used for vascular procedures and holding delicate needles.
