2 - 1B surgical droid / Legends 2 - 1B surgical droids , also known as 2 - 1B medical droids , were advanced medical droids popular across the galaxy to those that could afford them . At some point , a 2 - 1B droid typically cost 4 , 300 credits . Description . The 2 - 1B series was humanoid , with many of its internal components visible through a translucent torso sheath . A 2 - 1B model ' s arms featured exceptional joint articulation with precision - crafted servogrip pincers at the end of each limb . Sometimes , in certain operations , these pincers could be removed and replaced with multiple arm attachments containing various medical tools and software packages , including hypodermic injectors and cutting saws . The droid model was highly advanced and intelligent with its programming being further advanced by some of the top physicians in the galaxy at the Rhinnal State Medical Academy , which also integrated heuristic processor s . The most useful characteristic of the 2 - 1B droids was the ease with which owners could update their programming and appendages . A 2 - 1B droid could easily become a specialist in neurosurgery , podiatry , pediatrics , cybernetic limb replacement , and alien biology with a trip to a certified service center . While advanced , 2 - 1B droids were generally paired with an FX - series medical assistant droid for medical assistance and detailed patient analysis . History . The 2 - 1B surgical droid was the result of a joint development project between Industrial Automaton and a small medical company known as Geentech during the final years of the Galactic Republic . It was developed in response to most medical droid models being unable to deal with sudden complications and to foresee unpleasant side effects in patients . Also , many patients were distrustful of being operated on by a droid . Geentech was able to address the first of these two problems by installing an advanced analytical and diagnostic computer in the 2 - 1B , making it an extremely intelligent droid unit . When the prototype matrices were completed , they were sent to the Rhinnal State Medical Academy where several of the top physicians in the galaxy enhanced its programming even further by integrating heuristic processors . The 2 - 1B was an instant success in the medical market and could be found at nearly every major clinic and emergency ward , and even on starships . It was notable for its familiarity with alien biology , most notably the Pui - ui species . A 2 - 1B could diagnose cardiac arrest in a hibernating Pui - Ui , deal with an enzyme eruption in the patient ' s third heart by inserting an Intravenous Access Unit catheter , and administer a mixed dosage of Iotramine and Clondex , as well as be aware that members of the species had a fatal allergy to perigen . This level of sophistication had not been seen in earlier droid models . Despite the 2 - 1B surgical droid ' s success , Geentech went bankrupt after the rival Genetech Corporation sued it over a copyright infringement in Geentech ' s similar name . However , Industrial Automaton acquired the rights to the 2 - 1B and continued production of the droid series . Despite its age , the 2 - 1B line continued to serve in a variety of medical and surgical capacities until the New Republic era . The proud and wealthy also used these droids to perform facial surgery and to burn away pockets of body fat . Notable units . Two 2 - 1B units were used by Emperor Palpatine in 19 BBY to resuscitate Anakin Skywalker , now Darth Vader , after his vicious scarring and dismemberment on the volcanic world of Mustafar at the hands of Obi - Wan Kenobi , replacing much of his body with bionic prosthetics . Another droid , known only as 2 - 1B , defected from the Galactic Empire to serve the Alliance to Restore the Republic . This droid was responsible for treating the famed Luke Skywalker in 3 ABY following his encounter with a wampa , and again later after his duel with Darth Vader , in which he lost his right hand . At least one red 2 - 1B unit served in the Theed Royal Palace in 32 BBY . At the same time , another unit served as a repulsorlift platform transport pilot for Coruscant Tours . Another known 2 - 1B unit was the medical droid known as Waste , who served on the Imperial prison barge " Purge " . He assisted Zahara Cody in attempting to treat those infected with the Blackwing Virus , and the droid was destroyed on board the " Purge " in 1 BBY by the zombie that it had been trying to treat . At least one more of these units was encountered by Cody aboard the Star Destroyer " Vector " , inside Bio - Lab 242 which Cody at first mistook as Waste . A 2 - 1B was found at the Aurora Medical Facility on Obroa - skai in 43 ABY .
