A powered surgical apparatus can be used with a source of irrigation fluid
and a source of suction. The powered surgical apparatus can include a
cutting blade assembly and a handle. The handle can include an upper
portion defining a distal section connectable to the cutting blade
assembly and a lower portion extending downwardly from the upper portion.
The handle can be connectable to the source of irrigation fluid and the
source of suction. The system can also include a manually actuable input
device that provides at least one signal relevant to at least one
operation of the system, and a controller that receives the at least one
input signal and provides an output signal to perform the at least one
operation of the system.
