CIS - Certified Instrument Specialist Robotic and Powered Instruments Questions and Answers

Question 1

A technician is processing a da Vinci robotic instrument and notes the manufacturer's instructions for use (IFU) specify a limited number of uses.
What is the primary patient safety reason for this limitation?

Accepted Answer

The internal mechanical components, such as cables and pulleys, are subject to metal fatigue and may fail intraoperatively.

Answer

The instrument's internal software becomes outdated after a set number of procedures.

Answer

Frequent sterilization cycles degrade the external insulation, making it unsafe.

Answer

The limited use policy ensures hospitals must repurchase instruments, supporting the manufacturer's business model.

Question 2

When preparing a battery-powered surgical instrument handpiece for sterilization, what is the most critical step?

Accepted Answer

The battery must be removed, and the handpiece and empty battery housing processed according to their IFUs.

Answer

The battery should be left in place to keep the internal components sealed.

Answer

The handpiece should be placed in a peel pouch with the trigger lock in the 'off' position.

Answer

The battery contacts on the handpiece should be coated with a protective lubricant.

Question 3

Which of the following is considered the most effective method for detecting non-visible micro-tears and pinholes in the insulation of a robotic instrument's shaft?

Accepted Answer

Using a specialized electronic insulation integrity tester.

Answer

Submerging the instrument in saline and looking for air bubbles.

Answer

Running a damp, conductive cloth along the shaft to feel for snags.

Answer

Visually inspecting the shaft under a high-powered magnifying lamp.

Question 4

A sterile processing technician is manually cleaning complex robotic instruments. Which step, mandated by most manufacturers, is essential for cleaning the internal channels and lumens?

Accepted Answer

Flushing designated ports with a prescribed volume of cleaning solution using a syringe or automated irrigator.

Answer

Using a high-pressure air hose to blow out debris.

Answer

Scrubbing the exterior with a wire brush to remove baked-on soil.

Answer

Soaking the instrument in a bleach solution for at least 10 minutes to ensure disinfection.

Question 5

When processing a pneumatic (air-powered) surgical handpiece in the decontamination area, which action is strictly forbidden by most manufacturers to prevent damage?

Accepted Answer

Submerging the entire handpiece in water or enzymatic solution.

Answer

Wiping the exterior of the handpiece with a germicidal cloth.

Answer

Operating the trigger mechanism to check for smooth action.

Answer

Using a soft brush to clean the distal chuck or collet.

Question 6

An orthopedic surgeon uses a single-use sagittal saw blade during a procedure. After the case, what is the proper handling procedure for the used blade?

Accepted Answer

Dispose of it in a designated sharps container in accordance with facility policy.

Answer

Send it to the sterile processing department to be sharpened and resterilized.

Answer

Clean it and return it to the loaner tray it came with.

Answer

Place it in the regular biohazard waste bag.
