Abstract: 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 or 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.

Abstract: An apparatus and method of securing an elongate member to a medical instrument. The apparatus comprising an attachment device including a base, a liner, and an adhesive. The base comprising an aperture configured to receive the elongate member, wherein the liner may be positioned adjacent the aperture and axially aligned with the elongate member when the attachment device is coupled to the medical instrument. The attachment device may comprise a pair of apertures and the liner may be positioned adjacent the adhesive and at least partially between the pair of apertures. The method of securing the elongate member to the medical instrument comprises threading the elongate member through the aperture of the attachment device and adhering the attachment device to the medical instrument. The method of manufacturing the attachment device may comprise cutting the aperture in the base, the adhesive, and liner.
