FUE (Follicle Unit Extraction) question

[e2173412]

Hello everyone. I have a question about the FUE (Follicle Unit Extraction) method of hair transplantation.

I understand how the follicular unit is inserted with a "Choi Implanter Pen" or "Implanter pen". I understand how it works and I'm okway with it.
But I can't find out anything about the device which is used to collect the follicular units which is used by the implanter pen later on.
What is it called? Where can I learn more about it?
I'd like to know as much as I can about the procedure and the devices used and how they work before deciding what transplantation method to use.
Thank you!

it's called extraction punch
The diameter should be as little as possible, preferably under 0.7 mm, not to leave scars.

Thanks for the info. Yes something like 0.7mm seems like it won't leave much scarring.

What about making new holes to put the harvested follicles to? Is the same ~0.7mm 'punch' used?
