Medical droid/Legends

"Useless machine! Useless! Useless!"

- Darth Vader, in a fit of anger, attacking a 2-1B medical droid

Medical droids, medi-droids, meddroids, or Emdee droids were specialized in medical and surgical operations. A classification of first-degree droid, medical droids were actually considered to be members of the larger biological science droid classification, but were typically listed separately due to their prominence.

Overview
The galaxy was full of sentient species and it could be very hard for a flesh-and-blood doctor to know how to effectively treat more than a few of them. Medical droids had no such shortcomings, some even had a passable bedside manner. The most popular meddroids included the 2-1B surgical droid and FX-series medics. GH-7 medical analysis units were common throughout the Galactic Republic, while the Sith employed DD-13 medical assistant droids for their dark reconstruction surgery. There were even models that specialized in non-sentient creatures.

History
The Geeaych-Seven was also known as the GH-7 meddroid. Its data banks were filled with information about almost all medical problems, physical or mental. In 19 BBY, a GH-7 was deployed at Polis Massa Base to oversee the medical treatment of Padmé Amidala with the assistance of a Midwife droid as she gave birth to Luke and Leia.

A team of DD-13 cybernetic surgical droids were used to reconstruct Darth Vader in the Emperor Palpatine Surgical Reconstruction Center after he was severely injured in a duel with his former master, Obi-Wan Kenobi on Mustafar.

Luke Skywalker was treated in a Bacta tank operated by two medical droids, a 2-1B and an FX-7, in the Echo Base medical lab shortly before the Battle of Hoth in 3 ABY. The same droids would replace Skywalker's hand with a cyborg replacement after losing it to Darth Vader on Bespin.

Another medical droid pulled shrapnel out of Luke after his escape from the Cavrilhu Pirate Base.
