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.
