FLS FLS Camera Navigation and Optics

Question 1

The standard laparoscope used in FLS tasks has a 0° or 30° lens. What is the primary advantage of the 30° (angled) lens?

Accepted Answer

It allows the surgeon to 'look around corners' by rotating the scope

Answer

It provides a wider field of view without moving the scope

Answer

It magnifies the image more than a 0° scope

Answer

It produces less light loss than a 0° scope

Question 2

In FLS box trainer tasks, the camera is typically placed through which port?

Accepted Answer

The umbilical 10–12 mm central port

Answer

The rightmost 5 mm port

Answer

The left lateral 5 mm port

Answer

A dedicated 2 mm port at the top of the box

Question 3

When the camera is positioned too close to the target tissue in the FLS box trainer, the result is:

Accepted Answer

Loss of spatial orientation and inability to see instrument tips

Answer

Better magnification and improved task performance

Answer

Improved depth perception due to shorter focal length

Answer

Reduced glare from the light source

Question 4

White balancing the laparoscope before insertion is important because it:

Accepted Answer

Calibrates the camera to display accurate colors under the operative light

Answer

Sterilizes the lens surface

Answer

Increases the frame rate of the video system

Answer

Adjusts the focal length of the lens

Question 5

The phenomenon of 'fulcrum effect' in laparoscopy means that when the surgeon moves the instrument handle to the right, the instrument tip moves:

Accepted Answer

To the left (in the opposite direction)

Answer

To the right, as with open surgery

Answer

Straight upward due to leverage

Answer

Diagonally, depending on trocar angle

Question 6

Fogging of the laparoscope lens occurs when the scope enters a colder peritoneal cavity from a warm room. The most practical intraoperative remedy is:

Accepted Answer

Warm the scope tip in warm saline or use anti-fog solution before insertion

Answer

Increase insufflation pressure to clear the lens

Answer

Replace the camera with a 0° scope

Answer

Increase the light source intensity
