Q

Coblation Technology:
1. What is Coblation
2. What is Plasma?
3. What size is Plasma bubble?
4. How is it formed?

A
  1. Controlled Ablation using Glow Discharge Plasma
  2. 4th State of Matter (energised gas)
  3. 100-200um (microns)
  4. Current to electrodes
    - vapor layer forms
    - energy into vapor layer which forms plasma
    - plasma breaks water into free radicals

Q

Coblation Frequency:

S+N vs competitors?
why is low frequency better?
Bone damage?

A

100 kHz (low)
Stryker 180kHz
Mitek 288kHz

Low Frequency:
= Tissue provides high resistence, prevents conduction
= low tissue penetration
= PRECISE

Knee cartilage 500um
Plasma bubble 100-200um
= no damage to bone

Q

What is FLOW IQ?

A

Real time flow and energy regulation which adjusts for:
1 - Tissue Type
2 - Tissue Contact
3. Plasma Quality
= CONSTANT RESECTION

22
Q

Pump functions (3)

A
  1. Distend the joint
  2. Flush the joint
  3. Control bleeding

All whilst maintaining stable, set pressure

23
Q

Definition of Flow Rate and what it does

A

Amount of fluid that passes a given point in a given time
- Keeps joint clear
- Helps blades to cut
(litres per min)

24
Q

Two issues of wrong pressure

A

Pressure too high - EXTRAVASATION (fluid into surrounding tissues)

Pressure too low (eg shavers) distended joint will collapse
