    • A shaver blade assembly useable in either an irrigation-only mode, an aspiration-only mode or an irrigation/aspiration mode. The shaver blade assembly has a stationary elongated outer tube and a movable (e.g. rotatable) elongated inner tube, both inner and outer tubes having hubs attached to their proximal ends for attachment to a handpiece which provides power to move the inner blade relative to the outer blade. The inner and outer tubes are provided with cutting windows at their distal tips and the relative movement between these cutting windows acts to cut tissue during surgical procedures. The outer tube is provided with a fluid inlet port at the proximal end of its tubular surface and a fluid adapter is selectively attachable to the outer tube so as to provide a means for introducing irrigating fluid into the fluid port. The adapter is integrally formed with sealing surfaces which obviate the need for O-rings and the like. A longitudinally extending irrigating channel is provided between the inlet fluid port at one end of the irrigating channel and the outlet fluid port at the distal end of the irrigating channel by which fluid is communicated to the vicinity of the cutting windows when the shaver blade is used in the irrigation-only mode or the irrigation/ aspiration mode. The channel may be either the annular clearance space itself or a separate, dedicated groove or channel formed in the mating surfaces of the tubular members. Removing the adapter and the fluid supply enables the shaver to continue being used in an aspiration-only mode.
    • 一种剃须刀组件,其可用于仅灌溉模式,仅吸气模式或灌溉/抽吸模式。 剃刀刀片组件具有固定的细长外管和可移动的(例如可旋转的)细长的内管,内管和外管均具有连接到其近端的毂,用于附接到手持件,该手持件提供动力以使内刀片相对于外部 刀。 内管和外管在其远端尖端处设有切割窗,并且这些切割窗之间的相对运动用于在外科手术期间切割组织。 外管在其管状表面的近端处设置有流体入口,并且流体适配器可选择性地附接到外管,以便提供将冲洗流体引入流体端口的装置。 适配器与密封表面一体形成,这避免了O形环等的需要。 在冲洗通道的一端的入口流体端口与冲洗通道的远端的出口流体端口之间设置纵向延伸的冲洗通道,当使用剃须刀片时,流体与切割窗口相邻的位置被连通 在仅灌溉模式或灌溉/抽吸模式。 通道可以是环形间隙空间本身或形成在管状构件的配合表面中的单独的专用凹槽或通道。 卸下适配器和流体供应器可使剃须刀在吸气模式下继续使用。
