auto-doc bed(a way to do surgery to self)

[Wex]

Automedic could be powerless. You all know a powerless device is useless.
Automedic could be not yet "sure" technology. Let's say success ratio of 90% (with failure meaning a messy death, malus to survivors); would you test your luck if you had a medic there?
Automedic could be awfully pricey or require constant repairing.
They should always need medicine to work (hopper).
