Can anyone translate English to Japanese?

I need help naming one of my character's weapon. Her weapon looks something like a spear and battle axe combined. On one side the axe blade resembles a dragon wing, the other looks like fire. The 'wing' controls wind and the 'fire' controls....well....fire. =_= '

The spear head controls water/ice. I want to call the weapon 'Dragon Staff' (It reverts to something like a wizard's staff when not being used) and because the one who raised and gave her the weapon was Japanese, I want the name to be in Japanese. Unfortunately I only know snatches of words and phrases. If you could translate 'Dragon Staff' I would appreciate it. I know sometimes there isn't an exact translation for some things so don't worry too much of being precise. I'm open to any other suggestions, both English and Japanese. Also I can't read katakana or kanji so if you do type in either one, have pity on me and also type it out in the english alphabet so I can read it. : P

Thank you!
