1. A surgical instrument, comprising:
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, the shaft having a longitudinal axis extending between the proximal and distal ends;
a transmission housing at the proximal end of the shaft, the shaft being rotatably coupled to the transmission housing;
an actuator in the transmission housing, the actuator being operably coupled to actuate rotation of the shaft;
a port accessible from an exterior of the transmission housing, the port being configured to be fluidically coupled to a fluid supply; and
a manifold in the transmission housing, the manifold comprising 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,
wherein the shaft is rotatably coupled to the transmission housing, and in response to actuation by the actuator, the shaft rotates about the longitudinal axis of the shaft relative to the transmission housing and the manifold.
 
13. A surgical instrument, comprising:
a transmission housing;
a shaft comprising a distal end, a proximal end, and a wall surrounding an interior of the shaft, the shaft having a longitudinal axis extending between the proximal and distal ends, the proximal end of the shaft being rotatably coupled to the transmission housing at a rotational coupling;
an actuator in the transmission housing, the actuator being operably coupled to actuate rotation of the shaft;
a fluid port accessible from an exterior of the transmission housing;
a fluid connection locking mechanism coupled to the fluid port; and
a fluid manifold in the transmission housing,
the fluid manifold comprising an inlet and an outlet,
the inlet being in fluid communication with the fluid port,
the outlet being in fluid communication with the interior of the shaft,
wherein, in response to actuation by the actuator, the shaft rotates about the longitudinal axis of the shaft relative to the transmission housing and the fluid manifold.
