Arthroscopy Flashcards
Crossfire outputs how many watts of RF power?
400
Crossfire is compatible with ALL of the following Stryker products EXCEpT?
TPS power drills and TPS foot pedal
Crossfire is the only (blank) on market?
Console with a 2 in 1 platform that can control powered resection and RF

Name the cross blades in total offering
Smooth Bite
Aggressive Max
Dual Edge 4 mm, 5.5 mm
Tomcat HC 4 mm, 5.0 mm
T/F: Pressure in the joint will be nearly double the set pressure when there is little to no outflow in Dynamic Mode.
True
Crossflow features can be controlled by what devices outside of pump?
Shaver hand piece
iSwitch
SDC3 Voice Activation
Etc.
If your surgeon uses a drain cannula for his inflow source in a knee, which dynamic mode should be selected?
Dynamic - High
T/F: It is recommended to start Dynamic Mode set pressure lower than standard mode pressure settings because of added pressure buffer.
True
How do you connect competitor resection consoles to crossflow?
Competitive Integration Cables
MAP is a weighted average of:
Systolic pressure and diastolic pressure
T/F: Crossflow connects with Stryker resection consoles via USB
False
T/F: The outflow runway has two suction tubes, Shaver and RF
False
T/F: bleeding in the joint could occur if patient blood pressure increases and pressure within the joint drops.
True
T/F: Managed Outflow will reduce the risk of:
Extravasation
Crossfire is compatible with all Stryker products in arthro cases expect?
TPS Footpedal, TPS Power drills
T/F: the Crossfire console is fully programmable via the Customizer
True
T/F: Crossfire 2 console provides improved, best-in-class COAG capabilities
True
T/F: only select Serfas probes and Anvers can be used with Crossfire?
False
Crossfire outputs how many watts of RF power?
400
The crossfire console ships with how many default settings?
Three
T/F: pressing the arrow keys on Crossfire console will increase and decrease the CUt level on Serfas energy probes
True
Crossfire is the only (blank) on the market
Console with a 2 in 1 platform that can control powered resection and RF
Mac flow rates on crossflow allowed through 5.8 cannula with the different dynamic settings are as follows:
Dynamic High: 1.6L/min
Medium: 1.2 L/min
Dynamic Low: 0.4 L/min
What are the top three all purpose cutters?
Aggressive Plus, Resector, Tomcat
What are sizes and use cases for Dual Edge Crossblade Cutter?
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)
Tomcat - what are use cases and sizes
With serrated edges on the inner and putter cutting surfaces, tomcat is Stryker’s most aggressive soft tissue cutter
Knee - ACL and ACL stump resection
No suction. What should I do with crossflow pump?
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
What are contributors to aggressiveness of a shaver?
Number of teeth
Placement of the teeth (inner and outer)
Size of cutter
What contributes to aggressiveness of a bur?
Faster the RPM speeder
Fewer number of flutes
Larger the bur
Forward motion vs reverse
On crossfire 2, why would arc to scope damage decrease?
Scope is less resistant that tissue. It detects when the hand piece and disposable are getting close to scope.
What is the default handpiece button mapping specifics?
I - trigger/ON
II - osc vs fwd/rev
III— fwd vs rev
How much more resistant is SmoothBite cutter to arthrex’ Torpedo
100%
How many window styles on Cutter does Stryker offer?
Four.
Tomcat, aggressive max, dual edge, smooth bite
Sizes of diamond bur:
Why doesn’t it skip on bone?
4.0 and 5.5
Diamond is closer together on the head of the bur. Creates less skipping. Crossblade xl has a 71% reduced skip distance compare to average fluted bur.
