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.

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.
