Powered Instrument Care
What powers a pneumatic surgical instrument?
Compressed gas.
What is an endoscope used to do?
View internal body structures through an opening or small incision.
What integrity check is required for many flexible scopes before immersion, at the point specified by the manufacturer?
Leak testing.
Which term describes an implant removed from a patient?
Explant.
What is loaned instrumentation?
Instruments or sets borrowed from a vendor or another facility for use in a procedure.
What is fluid invasion in a powered instrument?
Unwanted liquid entry into internal spaces that are not designed to be exposed to fluid.
What is a lumen?
A hollow internal channel in an instrument or endoscope.
A scope fails its required leak test. What should happen next?
Stop routine processing, contain the device and follow the manufacturer failure pathway and facility reporting procedure.
A camera head and its scope look like one assembly. What determines their cleaning and microbial-control methods?
Each device and component IFU, intended use and compatible validated processing requirements. Their methods may differ.
What record helps identify missing or damaged items at receipt and before return?
An itemized inventory or inventory control sheet.
A powered handpiece has a metal outer case. What determines whether it may be immersed?
The current manufacturer instructions for the exact device and component. A metal case does not establish immersion compatibility.
Which scope type follows a relatively fixed viewing path and must not be bent: rigid or flexible?
Rigid endoscope.
Why does a completed AER cycle alone fail to prove that a scope is ready for use?
Required manual preparation, correct adapters and channel connections, compatibility, cycle results and postprocess steps must also be verified.
Why do robotic instruments require special attention during cleaning? Name two design features.
Examples include wristed tips, complex joints, internal channels and hidden surfaces that require prescribed brushing, flushing or connections.
A loaned tray arrives wrapped and appears clean. Can the receiving facility assume it is ready for surgery?
No. Complete the required receipt and reprocessing pathway, including verification of identity, condition, inventory and current IFUs.
A pneumatic hose has cracks and a swollen section. What should the technician do?
Remove it from service, identify the damage and follow the approved evaluation or repair pathway. Do not release it because the handpiece still runs.
What tool can help visually inspect the inside of an instrument channel?
Borescope. It supports inspection and does not replace cleaning.
A scope finishes HLD but a channel remains wet. What must happen before storage, and why?
Complete the validated drying method. Retained moisture can support microbial growth during storage.
A small insulation defect is found on an electrosurgical instrument, but its tip moves normally. Should it be released?
No. Hold it for authorized evaluation because damaged insulation can permit unintended electrical leakage despite normal mechanical movement.
A loaned set arrives shortly before surgery without its IFUs. What should the technician do?
Hold and escalate the missing instructions and insufficient processing time. Resolve the requirements before processing or release.
A powered device and its detachable battery have different processing requirements. How should the technician proceed?
Identify each component and follow its compatible IFU for removal, cleaning, drying, charging and any required sterilization. Do not apply one method to the entire assembly without validation.
A flexible endoscope looks clean externally. Why does this fail to establish internal cleanliness?
Channels, ports and other hidden surfaces may retain soil. Complete the required internal cleaning, inspection and cleaning verification under the IFUs.
Processing of a used scope was delayed beyond its manufacturer-specified interval. Can the technician simply begin the usual cycle? Explain.
Follow the exact manufacturer delayed-processing or recovery instructions and facility escalation procedure. The routine pathway alone may be insufficient.
A new patient-specific 3D-printed guide arrives without validated processing information. What should the technician do?
Hold and escalate the item. Verify intended use, material, sterile or single-use status and validated manufacturer instructions before selecting a processing pathway.
A vendor asks to collect a used loaned set immediately after surgery. What must the facility do before release?
Clean and decontaminate it under the manufacturer instructions and facility policy, reconcile the exit inventory and document its return status.
