CIS Robotic and Powered Instruments Questions and Answers 2 — Questions and Answers
Question 1: What is the primary challenge in reprocessing robotic surgical instrument arms?
- They are too heavy to handle
- Complex internal lumens, articulation joints, and electrical components require specialized protocols (Correct answer)
- They can only be cleaned by the manufacturer
- They do not need sterilization
Correct answer: Complex internal lumens, articulation joints, and electrical components require specialized protocols
Robotic instruments contain complex internal lumens, multiple articulating joints, and electrical connections creating difficult-to-clean areas requiring specialized protocols.
Robotic instruments present unique challenges: narrow channels for cables trap bioburden, wrist mechanisms create sheltered areas, electrical contacts need careful cleaning, and many have manufacturer-defined maximum use counts tracked by chip.
Question 2: How should battery-powered surgical instruments be handled during decontamination?
- Submerge completely with battery installed
- Remove the battery before cleaning and process each component per manufacturer protocols (Correct answer)
- Batteries need no processing
- Run the instrument while submerged
Correct answer: Remove the battery before cleaning and process each component per manufacturer protocols
Batteries must be removed before decontamination to prevent fluid damage. The handpiece and battery each have separate cleaning and sterilization protocols.
Battery-powered instruments require component separation. Battery packs have separate cleaning protocols (usually surface wiping). Handpieces follow manufacturer IFU for cleaning. Running battery instruments while submerged can drive fluid into internal components.
Question 3: What special consideration is required when sterilizing instruments with fiber optic components?
- They cannot be sterilized
- Fiber optic cables must be loosely coiled without sharp bends and protected from crushing (Correct answer)
- They require higher temperatures
- Fiber optics must be removed and sterilized separately
Correct answer: Fiber optic cables must be loosely coiled without sharp bends and protected from crushing
Fiber optic cables must be loosely coiled at minimum bend radius and protected from compression to prevent fiber breakage that degrades light transmission.
Fiber optic bundles break when bent too sharply or crushed, causing progressive illumination loss visible as dark spots when tested against a light source. Cables should be loosely coiled within their natural curve and never stacked under heavy items.
Question 4: What is the significance of use-life tracking for robotic surgical instruments?
- A manufacturer suggestion that can be overridden
- Instruments have a validated maximum number of uses after which they must be retired (Correct answer)
- Only applies to warranty claims
- Number of uses does not affect performance
Correct answer: Instruments have a validated maximum number of uses after which they must be retired
Robotic instruments have validated maximum use counts after which mechanical reliability cannot be guaranteed, making retirement mandatory for patient safety.
Use limits are based on mechanical fatigue testing, material degradation from repeated sterilization, and cleaning efficacy decline. Most robotic platforms enforce limits via embedded chips. Circumventing use limits creates serious legal liability and patient safety risks.
Question 5: How should pneumatic surgical instruments be maintained during reprocessing?
- No special maintenance needed
- Flush internal air passages, inspect seals and O-rings, and lubricate per manufacturer specifications (Correct answer)
- Simply blow compressed air through
- Only wipe externally
Correct answer: Flush internal air passages, inspect seals and O-rings, and lubricate per manufacturer specifications
Pneumatic instruments require flushing air passages, inspecting seals and O-rings, and applying manufacturer-specified lubricant.
Pneumatic instruments require: air passage flushing to remove blood drawn in during use, seal inspection to maintain operating pressure, lubrication of bearings and moving parts, and exhaust port cleaning. All steps must follow the manufacturer's IFU.
Question 6: What testing should be performed on powered instruments after reprocessing?
- No testing needed if they look clean
- Functional testing including power activation, speed control, torque, and attachment security (Correct answer)
- Only visual inspection
- Testing only during annual maintenance
Correct answer: Functional testing including power activation, speed control, torque, and attachment security
Powered instruments must undergo functional testing after every reprocessing cycle including power, speed, torque, and attachment security.
Testing includes: power activation without hesitation or unusual noise, speed control responsiveness, direction control engagement, torque output adequacy, chuck security, trigger function, battery charge level, and irrigation function if equipped.
