Trypanophobia is fear of what

Fear of needles
Fear of needles, known in the medical literature as needle phobia, is the extreme fear of medical procedures involving injections or hypodermic needles.

It is occasionally referred to as aichmophobia, belonephobia, or enetophobia, although these terms may also refer to a more general fear of sharply pointed objects. It has also been referred to as trypanophobia, although the origin and proper usage of that term is highly controversial.
