Question: What are the laparoscope diameters?
ANSWER: 2-10 mm
Question: Which degree scope is best for a field in line with
port?
ANSWER: 0 degree
Question: How to prevent fogging of scope?
ANSWER: Use anti-fog solution or put scope in hot water/hot
bath
Question: What is the most commonly used light source?
- | P a g e
ANSWER: 300 W Xenon lamp
Question: What if there is initial low pressure and high flow rate
at entry?
ANSWER: Leak in insufflator circuit; make sure everything is
plugged in correctly
Question: Benefits of monopolar?
ANSWER: Tissue is heated quickly, less thermal
damage/coagulation
Question: Monopolar voltage/frequency?
ANSWER: Low voltage/High frequency
- | P a g e
Question: What does coagulation mode do?
ANSWER: Rapid surface heating with shallow depth of
necrosis, intermittent waveform with higher voltage
Question: Risk of monopolar?
ANSWER: Current can be diverted through unintentional
pathways, leading to inadvertent tissue injury. Don’t use hybrid ports that mix metal with plastic.
Question: Why do you need a grounding pad for monopolar?
ANSWER: Capacitative coupling—transfer of energy between
two conductors separated by an insulator, transfer to passive electrode. Can release with tissue injury, but no issue if ground plate is working as capacitor can’t store the charge.
Question: Benefits of bipolar?
- | P a g e
ANSWER: Lower energy, producing less lateral tissue damage
and necrosis. Don’t need a grounding pad.
Question: Risk of bipolar?
ANSWER: Risk of cutting patient vessels before adequate
sealing, and device doesn’t work if there is metal between the jaws.
Question: Risk of ultrasonic dissection (harmonic)?
ANSWER: Active blade can injure something due to high
frequency (50 mHz).
