Can I buy a print head?

I have buy Ultimaker2 last year, but my nozzle is completely blocked, there are so much carbide in my extruder. I would like to buy a new nozzle so that I can fix it. But I see that "Hot end pack" have too much things that I don't needed, can I buy only nozzle(For 5mm fragment)?
