    • A cutting blade assembly for use with a handpiece having a motor for rotatably driving the cutting blade assembly. The handpiece has a bore therein for receiving the cutting blade assembly. The cutting blade assembly includes an elongate tubular outer member having a distal end with an opening thereat, a proximal end, a hub unremovably secured to the proximal end so as to be a permanent part of the outer member. The hub is configured to be directly received and engaged in the handpiece bore. An elongate inner member is received in the outer member and has a distal cutting end disposed adjacent the opening in the distal end of the outer member. A proximal end of the inner member is adapted to be received in the handpiece bore and rotatably driven by the motor to rotate the inner member in the outer member. The cutting blade assembly includes the elongate tubular outer member having a radially inwardly facing surface along the length thereof with at least one elongate axially extending groove therein, the groove terminating at both the proximal and distal ends of the outer member. The cutting blade assembly also includes the outer member additionally having an irrigation liquid connection structure and a window through a wall of the outer member for providing liquid communication between the liquid connection structure and the elongate axially extending groove so that liquid will traverse the axial extent of the groove and to the opening. Bearings relatively rotatably support the inner and outer members and the irrigation liquid bypasses the bearings through the groove.
    • 一种用于具有用于可旋转地驱动切割刀片组件的马达的手持件的切割刀片组件。 手柄在其中具有用于接收切割刀片组件的孔。 切割刀片组件包括细长的管状外部构件,其具有远端,其中具有开口,近端,不可移动地固定到近端的毂,以便是外部构件的永久部分。 轮毂构造成直接接收并接合在手持件孔中。 细长的内部构件容纳在外部构件中并且具有邻近外部构件的远端中的开口设置的远端切割端。 内部构件的近端适于容纳在手持件孔中并由电动机可旋转地驱动以使内部构件在外部构件中旋转。 切割刀片组件包括细长的管状外部构件,其具有沿其长度的径向向内的表面,其中具有至少一个细长的轴向延伸的凹槽,所述凹槽终止于外部构件的近端和远端。 切割刀片组件还包括另外具有冲洗液体连接结构的外部构件和通过外部构件的壁的窗口,用于在液体连接结构和细长的轴向延伸凹槽之间提供液体连通,使得液体将横过轴向延伸的 凹槽和开口。 轴承相对可旋转地支撑内部和外部构件,并且冲洗液体通过凹槽绕过轴承。
