This is a "Phalaenopsis type" Dendrobium from Dendrobium section Phalaeanthe, so-called due to the superficial resemblance to Phalaenopsis (moth orchid) flowers. You probably won't be able to accurately identify it beyond that (which doesn't mean you can't enjoy it!)
The canes will not grow new leaves. Some Dendrobiums grow baby plants (keikis) on the canes, and those will have leaves.
Even if they don't have leaves, the old canes will help the plant as long as they have not turned completely dry. Think of them as energy storage for future flowers.
