You probably mean the chain of fate, but that's located on their chest. And regarding his Bankai, it was stated that it puts a lot of strain on his body when he uses it. I take it that he would be unable to use it because the power would be too much for his body to handle when he was injured, or something like that.

Regarding Cang Du, I will be disappointed if he's already dead. He hasn't had enough character development, and we've seen too little of his abilities, particularly what "The Iron" means.

I hope he survives long enough to use more of his abilities, and to show what "The Iron" means.
