>or use a wand?
If we are talking AD&D: no.
Pic realted is a breakdow of what actions can be taken in a round. As you can only take one action and casting spells/wands is different from moving (A, fleeing, or E, closing), the answer is no.
>interruption
Spells can be interrupted RAW and that's a good thing , ut magical devices not so much.
I guess if you attack the wizard's wand like you would attack a Mind Flayers separate tentacle (possible RAW)?
Item saving throws crushing/normal blow category) should absolutely apply in that case.
