    • Disclosed is a surgical instrument for removing bone, cartilage, or similar tissue, comprising a shaft that extends in a longitudinal direction and supports a cutting plate at the distal end thereof, said cutting plate being inclined perpendicular or relative to the longitudinal direction, and a cutting element which is movably mounted on the shaft and supports a blade at the distal end thereof, said blade pointing in the direction of the cutting plate and being advanced to the cutting plate in order to cut tissue. The aim of the invention is to improve said surgical instrument in such a way that an operator can switch quickly, easily, and safely between different instruments. Said aim is achieved by disposing a first coupling element at the proximal end of the shaft, said first coupling element to be removably, positively connected to a driving device that is provided with a second coupling element which cooperates with the first coupling element, while embodying the first coupling element as a polyhedron whose outer surfaces point radially outwards from a longitudinal axis of the shaft.
    • 公开了一种用于去除骨,软骨或类似组织的手术器械,包括:轴,所述轴沿纵向方向延伸并且在其远端处支撑切割板,所述切割板垂直于或相对于纵向方向倾斜;以及 切割元件可移动地安装在轴上并在其远端处支撑刀片,所述刀片指向切割板的方向并被推进到切割板以切割组织。 本发明的目的是改进所述手术器械,使得操作者能够在不同器械之间快速,容易和安全地切换。 所述目的是通过在轴的近端处设置第一联接元件来实现的,所述第一联接元件可拆卸地可靠地连接到驱动装置,该驱动装置设置有与第一联接元件配合的第二联接元件,同时体现 第一联接元件作为多面体,其外表面从轴的纵向轴线径向向外指向。
