More Information
Summary:A medical puncture needle is configured to reliably administer a sufficient amount of a liquid medicine to thin tissue. The medical puncture needle includes: a main body having a cylindrical shape and having inside a through hole; a blade surface that has an annular shape and that is cut into a tapered shape so that a thickness of the main body reduces toward a tip part of the main body; and a blade edge that has an annular shape, the blade edge being formed at a tip of the blade surface so as to extend along a plane orthogonal to a central axis of the main body.
