The 2-ZH surgical droid was a medical droid produced by Industrial Automaton primarily for military applications.
Similar in many respects to the popular 2-1B surgical droid developed in conjunction with Industrial Automaton by Geentech, the green-shelled 2-ZH droid was commonly used in military prisons.[1]
In 11 ABY this type of droid "healed" Han Solo and Chewbacca during their imprisonment on Kessel.
