Complex surgical instruments

Endoscope

An instrument used to examine the interior of a hollow organ or body cavity.

Light-emitting diode (LED)

Semi-conductor diode that emits light when voltage is applied

Delayed Processing

Cleaning instructions for endoscopes that have not been processed within an hour after the completion of point of use treatment.

Fixative

A substance used to keep things in position or stick them together. A chemical substance used to preserve or stabilize biological material for examination

Loaned Instruments

Instruments or sets borrowed from a vendor or other facility for emergency or scheduled surgical procedures that will be returned following use.

The first step to inspect the insulation of a laparoscopic instrument is to:

Check the collar at the distal tip

Which of the following steps happens first when processing flexible endoscopes?

Leak testing

Pneumatic cords are a cleaning concern because

They are dark in color, so soil is difficult to see

The purpose of using a decontamination battery or hose when cleaning powered surgical instruments is to:

Keep fluid from entering the unit

One of the main reasons for powered surgical instrument repair is:

Lack of preventative maintenance (PM)

Powered surgical instrument attachments:

Can be peel packaged for sterilization if approved by the manufacturer

loaned instruments should:

Be decontaminated before use

Information regarding cleaning processes for endoscopes should be provided by the:

Instrument manufacturer

Which of the following statements about endoscopes is true?

Flexible endoscopes are time-consuming to clean

Electronic testing of laparoscopic insulation should be done

in the clean assembly area prior to set assembly

Pneumatic hoses:

Should be pressurized for proper inspection

Powered surgical instrument batteries should be charged per the manufacturers’ instructions for use (IFU):

Before Sterilization

Semi-rigid endoscopes:

Are used during urological procedures

Endoscoptic cameras:

Should be inspected for cuts, nicks, or other damage to the cable

Robotic instruments:

May have exposed cables
