the reason being is 99% of wands do NOT have healing requirements. They are either SMiting rods, or Holy Rods (divine) ... the only healing wands I have heard rumor of are pre order package wands that are already customized to your character. So you wont even access to them unfortuneately.
Good luck on your hunt though! (I'd switch an attribute as not to waste any more time on that one)
Staff ... I cant remembers at the moment though
