  • Patent number: 5766200
    Abstract: A rotatable shaver having inner and/or outer non-metallic elongated blades for use in endoscopic surgical procedures. In one embodiment a rotatable, elongated non-metallic inner tubular member is disclosed for use with a non-rotatable elongated metallic outer tubular member, the inner member having a flexible, non-metallic tubular body, a proximal hub and a distal tip provided with a cutting edge. The elongated tubular body of the inner member may be extruded or molded from a polymeric or composite material and may be bonded to or integrally formed with either the hub, the distal cutting tip or both. In one embodiment, the entirety of the rotatable inner tubular member (i.e. hub, tubular body and cutting tip) may be integrally formed as a single unit. In another embodiment, the outer tubular member is formed with a non-metallic tubular sheath within which a metallic or non-metallic inner member may rotate.

  • Patent number: 5601586
    Abstract: A surgical cutting instrument having an elongated rotatable inner member provided with a cutting edge at its distal tip, the inner member adapted to rotate within an elongated outer tube having a window adjacent its distal end adapted to cooperate with the cutting edge of the inner member. The outer tube is provided with a portion thereof adjacent its distal end which enables the distal tip of the outer tube to be bent at an angle relative to the proximal portion of the outer tube. The outer tube may be bent by a user into a selected angular position with the aid of a tool calibrated in a plurality of discrete positions. The tool is adapted to enable the outer tube to be rotated to any selected position prior to being bent so that the window at the distal tip of the outer tube may be caused to face in any desired direction relative to the bend in the outer tube.

  • Patent number: 5540708
    Abstract: A rotatable shaver having inner and/or outer non-metallic elongated blades for use in endoscopic surgical procedures. In one embodiment a rotatable, elongated non-metallic inner tubular member is disclosed for use with a non-rotatable elongated metallic outer tubular member, the inner member having a flexible, non-metallic tubular body, a proximal hub and a distal tip provided with a cutting tip having a cutting edge formed therein. The elongated tubular body of the inner member is mechanically joined at its proximal end to the hub and at its distal end to the cutting tip. The mechanical connection enables the transmission of torque from the proximal end of the inner member to the distal end while sufficiently holding the tip, tube and hub assembly together to enable insertion and removal of the assembly into and from the outer member.
