    Abstract: A cutting assembly in which an inner tube is rotatably disposed within an outer tube and defines as aspiration path. The inner tube may include segments, and the segments may define a flexible region associated with a bend of the outer tube. The outer tube may define irrigation channels, and further define irrigation apertures positioned proximal to a cutting window or distal to the flexible region. The irrigation channels fluidly separate the aspiration lumen from an irrigation path so as to prevent ingress of irrigation fluid into the aspiration lumen through slots defined by the segments. An inner jacket may be coaxially disposed within the inner tube and configured to provide a seal between the aspiration path and the irrigation path. A distal end of the inner jacket may be disposed in a counterbore, and the proximal end of the inner jacket may be proximal to the inner tube.

    Abstract: A surgical cutting assembly with an actuator assembly operable in a first mode and a second mode. A wheel is rotatable in a first axial position to rotate an intermediate tube for orienting a cutting window, and rotatable in a second axial position to rotate an outer tube for orienting a bend of a tube assembly. The actuator assembly may be operably coupled to the intermediate tube and operably decoupled from the outer tube in the first mode, and operably coupled to the outer tube and operably decoupled from the intermediate tube in the second mode. The actuator assembly may include a first gear, a second gear secured to the outer tube, and a third gear secured to the intermediate tube. A distal wheel portion and a proximal wheel portion may be discrete components coupled to one another to define a cavity for subcomponents of the actuator assembly.
