Most scopes rely on what rod Hopkins
lens system?
How does the Hopkins rod lens Reflected light is transmitted to coupler to light sensitive imaging
system work? chip in the camera head
As scope angle increases, light decreases
transmitted ___________
As length increases, light decreases
transmitted ________
What degree of scope is ideal 0 degree
for working in the pelvis and
high in the mediastinum
Look at fiber-optics
What do you do if your image is
Black spots = damage
blurry?
Assess for moisture
Inexpensive
Why is CO2 used in laparoscopy Not combustive
May not need tank
What happens if you warm CO2 Postop body temp and pain increases
How do you avoid losing Fully immersing suction tip in fluid being suctioned
pneumoperitoneum from
suction?
When is the picture in picture Hysteroscopy
effect helpful on the camera CBD exploration

Patient may not be significantly relaxed (sign: rhythmic
If measured pressure is same as abdominal muscle contractions)
preset pressure
Mechanical obstruction - kink in tubing, standing on tubing
, Make sure connected to port, check ports to make sure closed,
Low pressure, high flow rate
check ports for leaking, check distention of bowel or foley
Standby mode
Low pressure, no flow
Check gas level
NOT camera fog
Blank monitor
Check cords
Current flows through smaller tissue volume - less risk of lateral
tissue damage and necrosis
Benefits and risks of bipolar
current Risk of cutting vessels before sealing
Improper device function
Which current type does not Bipolar
require dispersive electrodes
At what temperature does Over 60 degrees celsius
protein denaturation occur?
How does coagulation occur Bonds are reformed in haphazard manner after heating
with monopolar energy
The tissue turning brown and Desiccation. As desiccation increases, impedance increases until
steamy with monopolar energy current stops flowing due to high resistance.
is a result of
The amount of current flowing Current density
through a cross sectional area of
tissue
Current density is _______ Inversely
proportional to tissue resistance
The _______ the contact area, the smaller
greater the current density and
faster heating
Cut
What are the three modes of
Coag
operation for cautery
Blend
Heat tissue quickly so cell water is converted to steam and the
What is the goal of cut energy
cell explodes
Why are you less likely to have Heat dissipated in steam
lateral thermal damage with
cut?
Unmodulated
Cut waveform
Low voltage
Coag
Fulguration is the result of ________
energy Rapid surface heating, superficial eschar formation, shallow
necrosis depth
Intermittent
Waveform for coag
High voltage
Why does coag have less Wide dispersement of heat
cutting potential
