It was a Medical Droid. In particular, a 2-1B (Too-onebee; I believe that's the one that actually did the work) and an FX-7.
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.
The droid in question is 2-1B, a medical droid.
From the Star Wars Wiki:
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 State Medical Academy of Rhinnal, which also integrated heuristic processors. 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 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.
