There are so many name and methods for FUE. I would like to organize them
in this form to make easy comparison.
| punch | motorized | unique point | |
| 2 step | sharp | no | |
| 3 step | sharp+dull | no | |
| Safe system | dull | yes | *1 |
| Roto core | sharp | yes | *2 |
| Neo graft | sharp | yes | *3 |
| Artas robotic | sharp+ dull | yes | *4 |
*1,Safe system
The initial rotation speed is only enough to allow the dull punch to penetrate
the skin and slow down the speed when pass deeper to separate the follicular
units from surrounding tissue. This will reduce transection rate of follicles.
*2, Roto core
Automatic rotation when downward pressure is placed. It has debris disposal
window to fasten disposal process and potential harm to the Punch tip.
*3, Neo graft
The device is used to extract follicular units and implant them in the recipient area
via a suction system. It seems a great idea, but has two major problems.
At first, suction has tendency to produce bare grafts. 2nd the contineous flows of air will dry up the delicate follicular units.
*4, Artas robotic
After initial calibration, the robot will work 100% automatic.
The quality of the grafts is excellent and transection rate is about 5-8%.
I would like to say it is the best way to have FUE procedure, if the price is
right.
