Abstract
A surgical instrument including an articulating region. An outer tube and an inner tube are axially fixed to one another distal to the articulating region and axially movable relative to one another proximal to the articulating region. Relative movement of the inner and outer tubes provides for articulation of the articulating tube assembly to a curved configuration. A working tool may be removably directed through a central cannula defined by the inner tube. The working tool may include a shaft having a flexible region configured to be arranged within the articulating region. The shaft may rotate within the inner tube with the articulating tube assembly in the curved configuration. The working tool may include a housing hub configured to be coupled with a handle to removably position the flexible region within the articulating region. Multiple working tools may be interchangeably directed through the central cannula.
