The FX-series medical assistant droid, also referred to as Fixits, was a medical droid series line produced by Medtech Industries. Only ten models (FXs-1 through 10) were made. They were often immobile, cylindrical droids with numerous "arms" that assisted patients during surgery or other medical procedures. They could help by cutting away dead flesh, holding items, or even injecting bacta fluid (which was why they were occasionally constructed at command stations during times of war to save injured soldiers).
