Question 1

3 main design benefits of echelon + stapler and GST system

Answer 1

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

Question 2

Stages of compression

Answer 2

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

Question 3

3 Key benefits of the SLR

Answer 3

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

Question 4

SLR competitor

Answer 4

CORE Seamgaurd (absorption is 25-30 weeks)

SLR is 17 weeks

Question 5

Troubleshoot Echelon + Stapler

Answer 5

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

Question 6

Echelon 3000 trouble shoot

Answer 6

HBHO!!!!

Home button to reverse knife blade

Remove and reinstall battery

Home button again

Override

Question 7

What innovative technology was incorporated to the updated CONTOUR CURVED?

Answer 7

GST, 3D

Question 8

How many stages of compression does Medtronic Use

Answer 8

1, Focal compress, stage where stapler is fired

Question 9

Tag Line for Contour Curved cutter

Answer 9

40mm cut line 30mm space

Question 10

What are sizes and colors for Echelon powered circular device?

Answer 10

Purple: 23mm

White: 25mm

Blue:29

Yellow: 31

Question 11

How does GST compare from Circular stapler to Echelon +?

Answer 11

Circular: provides precise compression

Echelon +: controls tissue movement

Question 12

3 main benefits of the Powered Circular device:

Answer 12

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

Question 13

Key watch outs for the PVS:

Answer 13

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.

Question 14

How does MEGADYNE SMOKE EVAC minimize noise?

Answer 14

Connect cable and or the RF Sensor

Flow rate

Run time settings automatically turn on and off when pen is used

Question 15

MEGASOFT Return electrode pad benefits:

Answer 15

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

Question 16

Key features and benefits of GEM:

Answer 16

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

Question 17

How electricity is converted to ultrasonic energy

Answer 17

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

Question 18

What are the tones for harmonic?

Answer 18

First tone: energy is active

Second tone: call to action

Question 19

Tones for ENSEAL:

Answer 19

Activation tone: energy is being delivered

End tone: energy is no longer being delivered

Question 20

Steps for use for ENSEAL

Answer 20

Close

Seal

Cut

Open

Question 21

How is the ENSEAL curved jaw more efficient than ligasure Maryland?

Answer 21

Captures more tissue per bite

More secure grasping

More continuous shaft rotation

Question 22

5 factors that affect cutting and coag performance of harmonic devices:

Answer 22

Power Level

Blade Location

Blade pressure

Blade sharpness

Tissue tension

Question 23

3 phases of advanced hemostation mode and corresponding power level:

Answer 23

Preheating: high to reach desired temp

Vessel sealing: modulates at low power

Transection: high power to finalize transection

Question 24

Key features of harmonic 1100:

Answer 24

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

Question 25

ATT algorithm in adv bipolar (ENSEAL) vs ultrasonic (harmonic)

Answer 25

Adv bipolar: senses change in tissue condition by measuring electrical impedance, generator adjust energy for precision and efficiency

Ultrasonic: monitors mechanical impedance by changes in blade frequency and generator optimizes energy delivery.

Question 26

How does LARGE JAW achieve better hemostasis than ligasure impact?

Answer 26

Larger distal tip electrode surface area

Question 27

What are the 3 grips when using the Zip pen smoke evacuation pencil?

Answer 27

Traditional

Overhand

Trigger (eliminates 100% of torque)

Question 28

Generator tones associated with ENSEAL:

Answer 28

Activation tone: energy is being delivered

End tone: energy is no longer being delivered
