Abstract: In accordance with at least one exemplary embodiment, a surgical instrument comprises a shaft comprising a distal end, a proximal end, and a wall extending from the distal end to the proximal end, the wall surrounding an interior of the shaft. A transmission housing is located at the proximal end of the shaft and the shaft is rotatably coupled to the transmission housing. An actuator in the transmission housing is operably coupled to actuate rotation of the shaft. A port in the transmission housing is configured to be fluidically coupled to a fluid supply. A manifold in the transmission housing comprises an inlet and an outlet, the inlet being in fluid communication with the port, the outlet being in fluid communication with the interior of the shaft at the proximal end of the shaft. The fluid communication of the inlet with the port and the fluid communication of the outlet with the interior of the shaft are maintained through a range of rotational orientations of the shaft relative to the transmission housing.

Abstract: In accordance with at least one exemplary embodiment, a surgical instrument comprises a shaft comprising a distal end a proximal end, a wall extending from the distal end to the proximal end and having an exterior surface and an interior surface. At least a first portion of the shaft may include openings that penetrate the interior and exterior surfaces of the wall and provide flow communication from an exterior of the shaft to an interior of the shaft. At least one transverse cross-sectional plane and at least one longitudinal cross-section plane through the portion of the shaft including openings may each intersect multiple openings that penetrate the interior and exterior surfaces of the wall. The surgical instrument may include a manifold in flow communication with an interior of the shaft. The surgical instrument may include a flexible sleeve located inside the interior of the shaft.

Abstract translation: 根据至少一个示例性实施例，外科器械包括轴，所述轴包括远端近端，从远端延伸到近端并具有外表面和内表面的壁。 轴的至少第一部分可以包括穿透壁的内部和外部表面的开口，并且提供从轴的外部到轴的内部的流动连通。 穿过包括开口的轴的部分的至少一个横截面和至少一个纵向横截面可以各自相交穿过壁的内表面和外表面的多个开口。 外科器械可以包括与轴的内部流动连通的歧管。 外科器械可以包括位于轴内部的柔性套管。
