Surgical Instrumentation Flashcards

Which instrument is specifically designed to grasp and excise small tissue samples for pathological examination?

Answer: Biopsy forceps or punch

Biopsy forceps and punch instruments are designed with cupped or cutting jaws to grasp and remove small tissue samples while preserving sample integrity for laboratory analysis.

A trocar is used in surgery primarily to:

Answer: Create a puncture opening through which cannulas or instruments can be inserted

A trocar is a sharp-pointed instrument used to puncture the body wall, establishing an access port through which cannulas and laparoscopic instruments are introduced into a body cavity.

Microsurgical instruments differ from standard surgical instruments primarily because they are:

Answer: Significantly smaller and engineered for use under microscopic magnification

Microsurgical instruments are miniaturized, ultra-precise instruments engineered for procedures performed under microscopic magnification, requiring careful handling to prevent damage to delicate tips.

What is the primary purpose of a bone curette?

Answer: To scoop and scrape bone tissue or soft tissue from a cavity

A bone curette has a spoon-shaped or loop-shaped working end designed to scoop and scrape bone and soft tissue from cavities, common in orthopedic, neurosurgical, and dental procedures.

A malleable retractor is advantageous in surgery because it can be:

Answer: Bent by the surgeon to conform to the anatomical contours of the surgical site

Malleable retractors are made of soft, bendable metal that can be shaped by hand to the exact configuration needed to retract tissue at a specific anatomical location, maintaining that shape during the procedure.

Surgical stapler instruments benefit the operative team primarily because they:

Answer: Rapidly place a line of staples to join tissue edges, significantly reducing closure time

Surgical staplers deploy a linear or circular row of metal staples to join tissue edges (anastomosis or closure) in a single firing, dramatically reducing the time required compared to hand suturing.

Powered surgical instruments (e.g., drills, oscillating saws) require special processing considerations primarily because:

Answer: Their complex mechanisms, internal lumens, and components require specific disassembly and manufacturer-directed protocols

Powered instruments have intricate internal components, air or electrical connections, and internal lumens that require complete disassembly, targeted cleaning, lubrication, and manufacturer-specified sterilization methods to ensure both function and sterility.
