|20140180104||ULTRASONIC PIERCING NEEDLE - An ultrasonic puncture needle for conducting puncturing while observing a puncturing condition by an ultrasonic image, includes a needle tube main body including an edge at its tip end, and a plurality of corner cube mirrors provided at a predetermined position of the needle tube main body, wherein the plurality of corner cube mirrors are provided in parallel with a center axis of the needle tube main body.||06-26-2014|
|20120117807||ULTRASONIC PIERCING NEEDLE - A puncture needle capable of clear imaging even if an angle to the irradiation direction of a detection wave is small. According to one embodiment, a ultrasonic puncture needle that conducts puncturing while observing a puncturing condition by means of a ultrasonic image is formed with an edge at the tip end of a puncture needle body, and formed at a specified position of the puncture needle body with at least one corner cube mirror formed by a triangular pyramid recess. Since a ultrasonic wave oscillated from the ultrasonic probe is reflected off the corner cube mirror to be returned to the ultrasonic probe, the reflected wave progresses in the same direction as the incident direction of the ultrasonic wave to be positively returned to the probe even when an angle formed by the irradiation route of a ultrasonic wave and the axis of the puncture needle is small.||05-17-2012|
