Abstract
An angled rotary tissue cutting instrument includes an outer member or blade, having a rigid outer tube with proximal and distal portions connected by a bend, and an inner member or blade rotatably disposed within the outer member and including an inner tube of integral one-piece construction having a spiral cut formed therein between proximal and distal ends thereof to define a flexible region adjacent the bend, and at least one layer of a spirally wound strip of material superimposed over the spiral cut portion of the inner tube. The spiral cut preferably extends to a cutting tip at the distal end of the inner tube so that the inner member can be bent closer to the distal end thereof to access difficult to reach areas of the head and neck, and other parts of the body.
