Abstract
A cutting assembly configured to be removably coupled to a drive assembly of a surgical instrument. An inner tube is coaxially and rotatably disposed within an outer tube and defines a lumen in communication with a cutting window. A drive hub is coupled to a proximal end of the inner tube to define a suction path through the hub member and the inner tube. A hub member of the drive hub defines a first aperture, and further defines a reduced aperture. A diameter of the lumen of the inner tube is less than the inner diameter of the reduced aperture of the drive hub such that resected tissue moves from smaller to larger cross sectional portions of the suction path at an interface between the drive hub and the inner tube. The drive hub may include a lip disposed within the suction path with the inner tube abutting the lip.
