Abstract: A cutting accessory for a surgical instrument. The cutting accessory includes a tube assembly (38) including an outer tube having at least one slotted region (50) configured to be bent to a shaped configuration and maintain the tube assembly in the shaped configuration. The slotted regions may be a proximal slotted region spaced apart from a distal slotted region to define a rigid intermediate segment, and a rigid distal segment of the tube assembly. The proximal or distal slotted regions may be at different rotational orientations. The spacing between adjacent slots of the proximal slotted region may be different than spacing between adjacent slots of the distal slotted region. The tube assembly may be shaped with an initial prebend at a predetermined angle and configured to be bent relative to the predetermined angle. The tube assembly may be a two-tube or three-tube arrangement.

Abstract: A cutting accessory for a surgical cutting instrument. The cutting accessory includes a sensor assembly including at least one sensor coupled near a cutting tip of a tube assembly. The tube assembly may be straight, bent, rigid, or malleable. The sensor assembly may include a substrate coupled to the outer tube with electrical traces disposed thereon in a twisted pair configuration. The sensor may be a coil sensor wound about an insulative spacer coupled to a distal region of the substrate. The coil sensor is electrically coupled to the electrical traces. A flexible region of the substrate may traverse the bend or malleable region, and the electrical traces may be in a linear configuration within the flexible region. The sensitivity of the coil sensor may be based on the properties of the tube assembly, and/or the axial location of the coil sensor relative to the cutting tip.

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 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.

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: An interactive computerized game system including a visual display, one or more user input devices, and a processor executing software that interacts with the display and input device(s) is disclosed. The software displays images of musical targets on the visual display, the musical targets possibly corresponding to a pre-recorded source of music. At least one of the user input devices is a touchscreen arranged to simulate a portion of a musical instrument. During gameplay, the gameplayer must touch the touchscreen at the appropriate time and/or in the appropriate location in response to the displayed images of musical targets. The system provides a positive indication if the player's input matches the attributes of the displayed musical targets.
