Microdebrider with improved cutting and reduced clogging

A device for removing tissue, comprising:

• a housing having an outer tube extending therefrom including a longitudinal axis defined therealong;
• a middle tube operably supported concentrically within the outer tube by a bushing and configured to extend from a distal end thereof, the middle tube including an opening defined at the distal end thereof having an edge on at least one side thereof, the middle tube including a swaged portion defined therein extending proximally relative to a distal end of the opening, the swaged portion configured to increase the inside diameter of the middle tube proximate the area of operative engagement between the middle tube and the outer tube;
• and
• an inner tube concentrically disposed within the middle tube including an opening having a series of teeth at a distal end thereof in longitudinal registration with the opening in the middle tube, the inner tube adapted to couple to a power source such that, upon activation thereof, the inner tube rotates relative to the middle tube and the series of teeth and the edge of the middle tube cooperate to cut tissue or bone disposed therebetween, the inner tube defining a lumen therethrough and extending therealong from the opening, a portion of the lumen adapted to connect to a suction source,
• wherein the swaged portion of the middle tube and the increased diameter associated therewith allows the inner tube to maintain a constant inner diameter along a length thereof reducing potential choke points along the lumen to the suction source.
