GH - 7 medical analysis unit The GH - 7 medical analysis unit was a model of medical droid in operation during the final years of the Galactic Republic . It was manufactured by the Chiewab Amalgamated Pharmaceuticals Company in competition with Geentech ' s 2 - 1B , and designed by a group of Columi . The GH - 7 was a multi - purpose automaton designed to handle diagnostics and surgical assistance duties . Though reminiscent of a humanoid form , the GH - 7 was not modeled on any particular species , instead designed to perform efficiently on a variety of outlying worlds among any number of alien races . The droid had access to a range of medical duties , all the while wirelessly connected to the current medical facility ' s main computer . Also , it could serve as an assistant to an organic medic , as it was made so that all of its tools were easily accessible . The GH - 7 was used on many Outer Rim medical outposts , including the CIS facility on Boz Pity and the medical center on Polis Massa . Several decades later , the GH - 7 would find use at the Aurora Medical Facility on Obroa - skai . History . Chiewab Amalgamated Pharmaceuticals Company , though one of the galaxy ' s largest medical corporations , was not known for making droids . The company could have gained the opportunity to become a forerunner and lead player in the droid market , however , if it had not spun off its subsidiary unit , Geentech . Geentech soon proved too valuable to lose when the company introduced the 2 - 1B , but by then it was too late to claim copyrights on the valuable property . Before Chiewab could even have a chance , Industrial Automaton swooped in and absorbed the solo franchise . Ever since , Chiewab worked to make amends for the 2 - 1B with the GH - 7 , its best contender . Using a percentage of the company ' s vast profits Chiewab hired a droid design staff comprised entirely of the highly intelligent Columi . The intellectual species ' love for logic and efficiency in engineering were qualities expressed in the creation of the GH - 7 . However , Core World medical facilities continued to purchase the more sophisticated 2 - 1B or the broader MD - series medical specialist droid s , making the Outer Rim a more welcoming market for the droids . After Padmé Amidala was injured by Darth Vader on Mustafar , she was taken to a medical facility on Polis Massa . There , this soft - spoken medical droid bore the news from the silent Polis Massan medics who worked diligently to save Padmé ' s life . Though they found nothing physically wrong with her , for reasons they could not pinpoint , she was losing her grasp on life . However , this news was mingled with hope for those present , Obi - Wan Kenobi , Bail Organa , and Yoda ; the Senator was pregnant with twins . Though the Polis Massan medics were unable to save Amidala ' s life , she did give birth to twin infants , Luke and Leia , giving these children a chance at life . A GH - 7 unit also assisted in treating the injuries of Jedi Padawan Zeami following the Battle of Coruscant . Design . The GH - 7 was a premier medical droid typically found in some of the better - equipped hospitals and as a personal physician to the wealthy . The GH - 7 was designed so as not to mimic any known species to ensure that a wide variety of aliens were comfortable being treated by the droid . The design settled on had a roughly humanoid torso , three main limbs , and a central head unit . The droid was kept easily customizable to account for last - minute emergency needs and use with non - Human races and was equipped with a heuristic processor to allow it to learn new techniques . A slit in the droid ' s chest also served as a hologram projector , which had the capacity to generate life - sized holograms of a patient in order to better illustrate the steps of a complicated procedure . A separate equipment tray was built into the droid ' s " crest " , which held such tools as scalpels , bone spreaders , and other diagnostic tools . Everything on the droid ' s body was arrayed to allow for easy access . The droid was mostly gray and black , with a bright green holoprojector , display , and photoreceptors , and a blue symbol on the droid ' s chest to mark the analysis chamber . On the droid ' s left hip was a black , L - shaped tray with another , smaller tray slightly above that . In addition to these , the droid boasted a specimen rack that protruded from its side and held sample jars or vials of live cultures . Repulsor fields kept the sensitive liquids perfectly balanced to inhibit spilling . The droid ' s torso sported three dexterous arms , two of which were connected to the shoulders and were single - hinged , with three dual - hinged manipulators . The third protruded from atop the right shoulder and was also single - hinged with two dual - hinged fingers . These three limbs allowed the droid to perform various delicate tasks , from collecting specimens to hypodermic injections . A fourth , less - noticeable arm housed a testing probe . This arm was used when analyzing a biological sample to insert the sample into the droid ' s built - in analysis chamber capable of two kilograms of storage . The head of the droid was a hammer - headed shape , with a flat " face " and a long sloping crest at the back of its head . A wire connected the crest to the back of the droid . Its photoreceptors were wirelessly linked to the medical mainframes of its current facility , as well as doubling as bioscanners and functions that included parallax brainwave readings as well as enabling the droid to see in dim lighting . A disc - shaped display screen exhibited video or pictographic information regarding the GH - 7 ' s testing results and its diagnostic conclusions . A comlink was built into the droid for communication over distances . The design of the GH - 7 was so successful that it won the Silver Bantha for excellence in industrial design four times and was recognized for its humanitarian work . The GH - 7 cost 4 , 840 credits , a price that made it rare to find on poorer worlds , though some patrons donated them to hospitals or clinics on fringe worlds or to serve as relief workers . Programming . The GH - 7 was programmed with considerable intelligence , enabling the droid to act as a diagnostician , a surgical assistant , anesthesiologist , and hematologist . The GH - 7 was also automatically programmed with the ability to speak Binary and was able to interface with a computer . The droid was , unlike most medical units , transported on and provided mobility by a single whisper - quiet repulsorlift cell for maximum mobility in an operating room and a crowded hospital and to reduce contact with potentially contaminated surfaces . The droid was programmed with a gentle , calming voice meant to soothe both the patients and their companions alike , in conjunction with this , the GH - 7 was programmed with a high degree of compassion , such that independent GH - 7s sought work in poor or troubled regions and attempted to heal whatever ill being it came across . It was also programmed with several mannerisms meant to give it a more benevolent and approachable feel , such as gestures or subtle movements or raises in pitch . Its largish head , while echoing the Columi ' s similarly oversized skull , gave the droid the look of a child , making it seem less threatening , as did the lack of any sharp edges and the rounded appearance . The droid was also inherently programmed with the physician ' s code and strong prohibitions against harming any intelligent organic being . This was so engrained in their programming that the droids were incapable of engaging in combat except to protect their patients , and even then only utilized weapons set to stun when against an intelligent , living target . Behind the scenes . The Polis Massan GH - 7 medical droid in " " was voiced by David Acord , who also served as the Assistant Sound Editor on " Revenge of the Sith " , Apprentice Sound Editor on " " , and Supervising Assistant Sound Editor on the DVD release of the original trilogy . Due to his cameo as the part , he named his " Star Wars " blog Experimental Surgery with GH - 7 , after the medical assistant .
