It depends on what was in Batman's belt at the time. If Batman had something to attack Ock's senses he would probably get reasonably far away via his rope and drop a sonic and flash grenade that would detonate on impact. Even if Ock batted them away he would still be effected by them. Exploding batarangs could work as well. Yes Ock could bat them away but the shrapnel from five or six of them would find it's way to his very human body. How well do the arms work once Ock himself is disabled? Do they continue to work on their own?
