    • A surgical apparatus for removing deposits from an interior of a vessel comprising a rotatable shaft and a rotatable tip mounted to the rotatable shaft which is rotatable about its longitudinal axis upon rotation of the shaft to remove deposits from the interior of the vessel. The tip has a distal portion, a proximal portion and an intermediate portion between the distal and proximal portions. The intermediate portion is defined by a plurality of transverse cross-sectional areas, wherein each transverse cross-sectional area defines first and second axes substantially perpendicular to each other to define a width dimension along a first axis and a height dimension along the second axis. The height dimension is greater than the width dimension.
    • 一种用于从容器内部去除沉积物的手术装置,包括可旋转轴和安装到可旋转轴的可旋转尖端,所述可转动的轴在轴的旋转时可围绕其纵向轴线旋转以从容器的内部移除沉积物。 尖端具有远侧部分,近端部分和远端部分和近端部分之间的中间部分。 中间部分由多个横截面区域限定,其中每个横截面区域限定彼此基本垂直的第一和第二轴线,以限定沿着第一轴线的宽度尺寸和沿第二轴线的高度尺寸。 高度尺寸大于宽度尺寸。
