Ultrasonically guided puncturing needle

摘要

An ultrasonically guided puncturing needle stabbed in a subject (P) being irradiated with an ultrasonic wave, the needle (30A) includes a cylindrical needle-like member (31A) having concaves (32A) and convexes (32D) formed on a peripheral surface of the needle-like member (31A) to reflect the ultrasonic wave, and a film (33A) formed on the peripheral surface on which the concaves (32A) and convexes (32D) are formed.
