Yup. Most of the best orb powers do not require you to cast through the orb at all - just to wield it.IOrb doesn't require you to cast with that implement, sword does. Just cast with the sword.
Staff of Ruin doesn't require you to cast with the staff, either, if you wanna be super-technical. That could easily be a DM's call, though.
