A cutting assembly for a surgical instrument including an outer hub, an outer tube, a cutting implement, and a drive hub. A retention flange of the drive hub is arranged to retain the cutting shaft within the outer tube. The cutting assembly may include a seal, and the retention flange may contact the seal. An irrigation spacer may provide a stop of distal axial movement of the drive hub for permitting fluid to flow through irrigation passageways. The drive assembly may include an irrigation port and a suction port with a proximal end of the irrigation port may positioned axially distal to a proximal portion of the suction port. The irrigation port may be coupled to a handpiece, and the suction port may be coupled to a back cap. A handpiece may include a saddle region, recesses, and/or an apex region to facilitate ergonomic handling of the surgical instrument.
