You're going to need to take that off.
Can't see from your picture, but usually there's one or two clamp bolts and maybe a positioning bolt running vertically (maybe from the triple clamp area to the clip on mount) After this it looks like you can just take it off the top of your fork.
IF the only damage in that area is the bend (see possible vertical bolt mentioned before) You might try bending it back yourself, if there's no kinks in the tube and the bend isn't bad.
Otherwise i'd be looking to wreckers for a spare, or maybe even a set of after market ones (replacing left & right so they are the same)
To help with your searching.... you're looking for a "clip on"... handle bars normally go from left to right, whereas the clip on (which you have) is clamp bolted to the top of the fork.
