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.

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.
