Q

Fenestration - its benefit

A

The presence of a window within the times of a jaw

allows for some tissue to protrude through the window in the tines, allowing for a more secure grip

Q

What happens if a higher closing force is applied

A

can create more pressure on the tissue, which can lead to relatively higher tissue trauma

Q

Lives/ fires - definition

A

the number of uses for which instruments are indicated

22
Q

When is an instrument life/fire used?

A

when the instrument has been installed and is brought under surgeon control

23
Q

What happens when the instrument is out of lives/fires?

A

it will not engage, and a message on the system will state that the instrument has expired.

24
Q

How many lives/fires for each:
8mm?
training instruments?
Clip appliers?

A

8mm - 10-18
training - 30
clip appliers - 100

25
Q

What happens if a higher closing force is applied

A

can create more pressure on the tissue, which can lead to relatively higher tissue trauma

25
Q

Where can the number of lives/fires be found?

A

in the settings tab, under uses remaining.

26
Q

Remote center - definition

A

a fixed point in space around which the surgical arms and cannulas move. Represented by a thick black band near the distal end

27
Q

Benefit of remote center technology

A

enables the system to maneuver instruments and endoscopes in the surgical site while exerting minimal force on the patients body wall

28
Q

29
Q

What are the 7 degrees of freedom?

A
  1. Insertion
  2. External Yaw
  3. External Pitch
  4. Roll
  5. Internal Yaw
  6. Internal Pitch
  7. Grip
30
Q

Insertion -definition

A

the direction of movement that adjusts the depth of the instrument tip

31
Q

External yaw - definition

A

side-to-side rotation around remote center

A

rotation of the instrument shaft around its own central axis

34
Q

Internal yaw - definition

A

Side-to-side rotation of the instrument jaws via the distal joint of the instrument wrist

35
Q

A

up and down rotation of the instrument tips via proximal joint of the instrument wrist

36
Q

Grip - definition

A

opening and closing of the instrument jaws

Q

Grasping

A

grabbing tissue within the jaws

39
Q

Retracting

A

lifting or pulling tissue by grasping or manipulating- tissue often left in place for periods of time (static)

40
Q

Dissecting

A

separation of tissue by using jaws in and opening or pushing/sweeping movement in order to expose surrounding structures

41
Q

cutting

A

incising without energy ( cold cutting)

42
Q

Needle driving

A

driving needles through tissue

43
Q

suture tying

A

forming knots and tightening knots in suture

44
Q

suture cutting

A

cutting through suture

45
Q

needle handling

A

gripping needles, but not driving through tissue

46
Q

suture handling

A

gripping suture without damaging suture

47
Q

coagulating

A

heating of tissue that causes the tissue proteins to form coagulum that seals the bleeding sites

48
Q

transecting

A

division by cutting across ( with or without energy)

49
