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 device (20) controllable by a surgical robotic system (100) is provided. The surgical device (20) includes a housing (32) capable of being coupled to the surgical robotic system (100); a drive system at least partially mounted in the housing (32); and a shaft (61) rotatably coupled to the drive system at a first end of the shaft (61). The surgical device (20) further includes a tissue-removal assembly (62) coupled to the second end of the shaft (61). The tissue-removal assembly (62) includes a first cutting member (37) having a plurality of rotatable blades (37A, 37B, 37C). The first cutting member (37) is coupled to a second end of the shaft (61). The tissue-removal assembly (62) further includes a second cutting member (36), one or more support elements (67) slidably or fixedly coupled to the second cutting member (36), and one or more extendable elements (66) slidably or fixedly coupled to the second cutting member (36).
