Title:
ULTRASOUND-GUIDED NERVE BLOCK NEEDLE
Document Type and Number:
WIPO Patent Application WO/2023/040471
Kind Code:
A1
Abstract:
An ultrasound-guided nerve block needle comprises a needle holder (2) and a needle tube (1). A front end of the needle tube (1) is cut along a diagonal direction to form a needle tip bevel (11). A front end of the needle tip bevel (11) is cut symmetrically in the vertical direction to form a faceted tip (111). The faceted tip (111) is in the shape of a bevel. A plurality of reflective recesses (12) are formed on an outer side of the needle tube (1). The center of the needle holder (2) is hollow in an axial direction. The rear end of the needle tube (1) is positionally limited to a step on the inner wall of the needle holder (2). A hole (21) is formed at the front end of the needle holder (2). The needle holder (2) is quadrilateral. A recess (23) is formed on one side of the needle holder (2). Both sides of the needle holder (2) adjacent to the recess (23) are provided with anti-slip surfaces (22). By providing corresponding recess structures at the needle tube (1) and the needle holder (2), the ultrasound-guided nerve block needle can be clearly visualized under ultrasound, and can also be easily distinguished from nerve tissue to determine the correct position of a puncture needle.
