In order to improve the visibility in ultrasound images, an oblique pattern is engraved on the surface of the needle.
Oblique intaglio prevents us to locate the insertion points in a straight line. This significant design could keep consistent stiffness of the needle against multiple punctures.
Ideal bidirectional bevel (B type) supports operators to collect more tissues with less punctures.

19G, 22G and 25G needles could meet the demands from users and each size has its own colors so that users are able to easily distinguish between sizes.
