    • A phacoemulsification tip is formed from a tube that encloses an aspiration lumen surrounded by and generally concentric with a structure section. The structure section has a plurality of structures (ridges, vanes, ribs, or fins). The plurality of structures project inward from an inner wall of the tube at the distal end of the tube. The plurality of the structures are disposed at an angle with respect to a face of the distal end of the tube. Alternatively, the plurality of the structures are disposed at a non-perpendicular angle with respect to a plane that is tangent to a curved outer surface of the tube.
    • 晶状体乳化尖端由包围由结构部分围绕并且与结构部分大致同心的抽吸腔的管形成。 结构部分具有多个结构(脊,叶片,肋或翅片)。 多个结构在管的远端从管的内壁向内突出。 多个结构相对于管的远端的表面设置成一定角度。 或者,多个结构相对于与管的弯曲外表面相切的平面以非垂直的角度设置。
