A puncture needle comprising:
- a needle body that includes a main portion and a distal portion tapering from the main portion and that is rotatable about a central axis of the needle body,
- the needle body including needle parts which are separated by a boundary along the central axis,
- each of the needle parts being independently translatable along the central axis,
- a surface of the needle body being configured for making contact with a subject to be punctured is smooth at least in the distal portion for reducing pain associated with rotation of the distal portion about the central axis of the needle body upon making contact with the subject.
