FX - series medical assistant droid / Legends 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 ) . During the Clone Wars , Galactic Republic forces often deployed FX - series droids by aerial insertion into forward positions and Republic Mobile Surgical Unit s , acting as mobile aid stations for critically wounded clone troopers . When Anakin Skywalker was grievously injured by Obi - Wan Kenobi on Mustafar , Palpatine brought him to a medical facility on Coruscant . Here , an FX - model droid worked on Anakin ' s body to bring him out of his critical condition . The droid later facilitated Anakin ' s transition to his half - cybernetic body . When Palpatine told the now - suited Darth Vader that Vader had killed Padmé , his fit of rage and grief caused Vader to destroy everything in the room with the Force , including the medical droids . The round " head " of the FX model that worked on Vader was crushed , as well most of its body . External containers holding presumably bacta shattered , spilling their contents . During the Galactic Civil War , both the Galactic Empire and the Alliance to Restore the Republic used FX models . Behind the scenes . incorrectly states that the FX series comprised only nine models . In the Battlefront series , FX medical droids acts as health - replenishing stations that automatically heal players whenever they stand nearby . Toy versions of FX droids . The FX first appeared in the vintage 3 3 / 4 - inch Kenner line in 1980 . Released on the new " The Empire Strikes Back " cards , FX - 7 is a unique figure in the original line , consisting of a gray tubular body and a head that can be spun 360 degrees and extended upwards by an inch . Underneath the head is a rigid white arm terminating in a claw appendage . This arm is mounted on a spinning ring , allowing it to be spun 360 degrees around the body . The main part of the body has nine white arms that can be opened out away from the body . Although these limbs have no joints , they can be slightly articulated at the elbow and shoulder . There is a major variation with the FX - 7 figure in that two different head molds exist . One head is smaller with differently situated detail from the other . Another shorter FX - 7 can be found on card ; this figure is simply missing its glued - on base that sometimes broke off during production . This shorter FX - 7 is not classed as a true variation but merely a production mistake . FX - 7 ran for five years through the " Empire " , " Jedi " and Tri - logo line . The next FX - 7 figure to be released came in the Power Of The Jedi line in 2000 – 2002 . This figure offers a far more realistic look and greater attention to detail than the vintage toy . Twice as many articulated limbs as the vintage figure , jointed at the elbow and shoulder , give it much more detail and capture a close likeness of the original production prop .
