Read the first 7 Surgical Equipment Technology flashcards as text

  1. A surgical laser system shows reduced beam power output despite the laser being fully charged. What is the most likely cause?

    Answer: Damaged fiber optic delivery cable

    Damaged or bent fiber optic delivery cables are a common cause of reduced laser power output due to increased transmission losses.

  2. Which grounding method is used in electrosurgical units to prevent alternate-site burns?

    Answer: Isolated patient return electrode monitoring

    Isolated patient return electrode monitoring (contact quality monitoring) detects poor contact and shuts off the ESU before an alternate-site burn can occur.

  3. During a robotic-assisted surgery, a robotic arm instrument fails to respond to surgeon commands. The FIRST step a BMET should take is:

    Answer: Check the instrument-arm communication cable connections

    Verifying cable connections is the first logical troubleshooting step before escalating to more invasive actions like rebooting or replacing components.

  4. What is the purpose of the smoke evacuator in a surgical laser procedure?

    Answer: Remove laser plume containing viable cellular material and toxic byproducts

    Laser plume can contain viable bacteria, viral particles, and toxic chemicals, making smoke evacuation an essential safety measure.

  5. A C-arm fluoroscopy unit drifts out of position during a procedure. Which component is most likely responsible?

    Answer: Brake or locking mechanism on the C-arm carriage

    A faulty brake or locking mechanism allows unintended movement of the C-arm, causing positional drift during procedures.

  6. Which sterilization method is CONTRAINDICATED for sterilizing powered surgical instruments with sealed electronics?

    Answer: Steam autoclave at 134°C

    High-temperature steam autoclaving can damage sealed electronics, batteries, and sensitive components in powered surgical instruments.

  7. What does the term 'blended mode' refer to in electrosurgical unit operation?

    Answer: A combination of cut and coagulation waveforms that provides simultaneous cutting and hemostasis

    Blend mode modulates the duty cycle of the cutting waveform to add hemostatic coagulation while still cutting tissue.
