SPY Flashcards
What are the specialties that allow DRE mode?
Arthroscopy, Cystoscopy, ENT, Laparoscopy
Can I used an ICG, other than AIM IC-Green?
The Stryker L10 AIM system is indicated for use with AIM ICGreen. Another solution is is considered off-label.
What is the native resolution in the 1588 AIM camera?
- HD 1920x1080p native resolution.
- CMOS 3-chip camera technology
- 9 specialty settings
How many built in lasers to L10?
Two built in lasers: IRIS and ENV
What are sizes of AIM laparoscopes?
5.4mm and 10mm laparoscopes
Proprietary lens technology
ENV
Endoscopic Near Infrared Visualization: laser within the light source that excites the AIM IC-Green causing it to fluoresce
ENV enables real time imaging of:
Vessels Blood flow Tissue Perfusion Major extra-hepatic bile ducts (Cystic duct, common bile duct, and common hepatic duct)
When excited by this near-infrared light, ICG emits light at what wavelength?
835nm wavelength (fluorescent)
ENV technology in the use of biliary mapping during lap chokes can be advantageous compared to use of intraoperative cholangiograms because:
Eliminates radiation exposure for staff, no risk of bile duct injury caused by insertion of trans cystic catheter, the average cost is $780
Gallstones:
May develop when there is too much cholesterol in bile secreted by liver
Can get lodged in the cystic duct, accumulate in the gallbladder or get stuck in the bile ducts where they can lead to inflammation or infection
Most common gastrointestinal disorder resulting in hospitalization
T/F aim safelight cable must be used with the aim platform in order for the advanced imaging modalities to function
True
There are four 1 cm incisions for portals. What are they?
Umbilicus
Anterior axillary
Midclavicular
Sub iPhone
The Common Bile Duct is formed by merging of what two biliary structures?
Where does it carry bile?
Common Hepatic Duct and Cystic Duct
Carries bile from the gall bladder and empties into upper part of small intestine
At what wavelengths do InfraVision and L10 emit infrared light?
InfraVision: 785nm
L10: 830nm
The Triangle of Calot refers to the anatomical space made up of which 3 anatomical structures?
Cystic Duct, Common Haptic Duct, liver margin (liver bed)
t/f: The strobing function can be activated from the camera head with the 1588 and L10 combo only
True
What is primary reason surgeons perform intraoperative cholangiograms?
Identification of gallstones, especially in common bile duct
CMOS
Complementary Metal-Oxide Semiconductor
Used for building circuits
It is recommended to inject _ to__ ml of ICG for assessment of biliary system
0.5; 0.75
When in spy modes, gain will adjust the intensity of the NIR signal the camera receives
True
Most surgeons rely on ______ mode for perfusion assessment
Contrast
Overlay does not allow for Auto Light and Over Lat simultaneously.
False
The _______ light source was the first introduction of multi color LED technology
L9000
Similar to 1588, the 1688 has 3 distinct laser levels to adjust
False
Though it appears to get brighter, again can only be adjusted in Oveay and ENV mode since Contrast mode only adjusts the light output
False
1688 ENV
Reduces spotlight Effect
1688 has an improved CSF mode due to increase in pixel density
False
Gain and brightness function can be applied to any buttons on the camera head in SPY mode
False
Why should I worry about perfusion in my bowel resection?
Besides technical aspects, adequate view perfusion is the main factor in ensuring integrity of an anastomosis
