24
Q

Mac flow rates on crossflow allowed through 5.8 cannula with the different dynamic settings are as follows:

A

Dynamic High: 1.6L/min
Medium: 1.2 L/min
Dynamic Low: 0.4 L/min

25
Q

What are the top three all purpose cutters?

A

Aggressive Plus, Resector, Tomcat

26
Q

What are sizes and use cases for Dual Edge Crossblade Cutter?

A

3.5, 4.0, 5.5mm

All in one functionality for tissue resection and bone debridement

Shoulder - rotator cuff and sub acromial decompression (4 and 5.5mm) , labral repair and glenoid boney work

Knee- all stump and notchplasty (5.5)

27
Q

Tomcat - what are use cases and sizes

A

With serrated edges on the inner and putter cutting surfaces, tomcat is Stryker’s most aggressive soft tissue cutter

A

Look for:

  • the pump connected to crossfire via FireWire cable
  • endure Neptune or similar device is not cranked too high
  • any of outflow cassette lines clogged
  • ensure resection device has correct dedicated suction
  • tubing clamped? Should be unclamped
29
Q

What are contributors to aggressiveness of a shaver?

A

Number of teeth
Placement of the teeth (inner and outer)
Size of cutter

30
Q

What contributes to aggressiveness of a bur?

A

Faster the RPM speeder
Fewer number of flutes
Larger the bur
Forward motion vs reverse

31
Q

On crossfire 2, why would arc to scope damage decrease?

A

Scope is less resistant that tissue. It detects when the hand piece and disposable are getting close to scope.

32
Q

What is the default handpiece button mapping specifics?

A

I - trigger/ON
II - osc vs fwd/rev
III— fwd vs rev
