the medical droid (the 2-1b) only treat luke, then is outclassed and destroyed. it never works on Vader
To the best of my knowledge he sees his lightsaber and severed hand falling below him.
Luke is resisting giving in to the Dark Side, so Darth Vader is fighting Luke with his light saber, and cuts off Luke's hand to show him his power, and to even further persuade him in joining him (Darth Vader) on the Dark Side. This act of cutting someone's hand off is called Cho Mai according to Jedi records. This is considered merciful by most Sith Lords who prefer killing their opponent.
Depends on how you look at it. Luke did cut off Vader's prosthetic hand and then realized he was doing wrong and he was going down the dark road when he saw his own prosthetic hand. Then of course, the Emperor took advantage of Luke refusing to give in to the dark side.
