3 main design benefits of echelon + stapler and GST system
Atraumatic pocket extension: hold tissue in place guiding staple legs towards pockets
Asymmetric staple legs with bent tips: mitigate trajectory due to remaining effects of tissue slippage
Close bottom cartridge channel: withstands high loads and stresses in thick or dense tissue firings
Stages of compression
Stage 1: PRE, 15 sec, management of tissue before firing device. Allows fluid to displace from tissue and prepares tissue for firing
Stage 2: Focal, device is fired
3 Key benefits of the SLR
Seamless application: simple click and go applicator for fast and easy buttress app
Seamless tissue manipulation: propriety buttress attachment material affixes buttress across entire anvil and cartridge face for no slipping, sliding, twisting, or bunching
Seamless performance: made from same trusted material used in vicryl and PDS sutures
SLR competitor
CORE Seamgaurd (absorption is 25-30 weeks)
SLR is 17 weeks
Troubleshoot Echelon + Stapler
RBRO!!!
Reverse knife switch forward to return knife to home position
Ensure the battery is securely installed
Reverse knife switch again
If knife doesnt return, then use manual override where the device will no longer be functional
Echelon 3000 trouble shoot
HBHO!!!!
Home button to reverse knife blade
Remove and reinstall battery
Home button again
Override
What innovative technology was incorporated to the updated CONTOUR CURVED?
GST, 3D
How many stages of compression does Medtronic Use
1, Focal compress, stage where stapler is fired
Tag Line for Contour Curved cutter
40mm cut line 30mm space
What are sizes and colors for Echelon powered circular device?
Purple: 23mm
White: 25mm
Blue:29
Yellow: 31
How does GST compare from Circular stapler to Echelon +?
Circular: provides precise compression
Echelon +: controls tissue movement
3 main benefits of the Powered Circular device:
GST: 33% reduction in compressive forces
Powered firing: 37% less movement at distal tip for increased stability and reduce force to fire by 97%
3D stapling: optimizes perfusion and reduces leaks by 61% at staple line
Key watch outs for the PVS:
Tissue is positioned proximal to the minimum cut line to allow for complete transection
Tissue is flat to avoid any bunching that may cause incomplete staple lines
Make sure you can see tips of the jaw to make sure no unintended tissue in jaws can result in incomplete cutting or improperly formed staples because does not have E beam.
How does MEGADYNE SMOKE EVAC minimize noise?
Connect cable and or the RF Sensor
Flow rate
Run time settings automatically turn on and off when pen is used
MEGASOFT Return electrode pad benefits:
Easy prep: no skin prep, no skin contact required, can be used w patient blankets or warming devices
Cost effectiveness: reusable up to 24 months, reduces SKU’S, reduces waste and waste disposal costs
Patient safety: eliminates adhesive related injuries, no electricity to or through patients, safe for patients with jewelry or tattoos
Been used in 100,000,000 cases
Key features and benefits of GEM:
Less instrument exchange vs scalpel (can be used for incision, coagulation, and dissection)
99.6% less hazardous surgical smoke compared stainless steel monopolar electrosurgery
Scalpel like cutting effect w significantly less lateral thermal spread than standard monopolar electrosurgery (tapered blade allows plasma to be created at lower temps
How electricity is converted to ultrasonic energy
Electricity travels from wall to generator, to transducer, piezoelectric ceramic discs cause friction, then sends vibration throughout the devices and causes blade displacement and friction when interacting with tissue
What are the tones for harmonic?
First tone: energy is active
Second tone: call to action
Tones for ENSEAL:
Activation tone: energy is being delivered
End tone: energy is no longer being delivered
Steps for use for ENSEAL
Close
Seal
Cut
Open
How is the ENSEAL curved jaw more efficient than ligasure Maryland?
Captures more tissue per bite
More secure grasping
More continuous shaft rotation
5 factors that affect cutting and coag performance of harmonic devices:
Power Level
Blade Location
Blade pressure
Blade sharpness
Tissue tension
3 phases of advanced hemostation mode and corresponding power level:
Preheating: high to reach desired temp
Vessel sealing: modulates at low power
Transection: high power to finalize transection
Key features of harmonic 1100:
Curved tapered tip for more precise dissection
Single energy activation button for reliable sealing of min and faster cutting with max up to 5mm
Improved algorithm to control blade heat to lower blade temp
Advanced hemostasis mode to seal vessels up to 7mm
Integrated transducer to simplify device set up and reduce SKU’S
