Surgical abrader with suction port proximal to bearing
First Claim
1. An apparatus for abrading tissue, comprising:
- a bearing tube having a distal end and a proximal end;
a suction port formed distally in a sidewall of the bearing tube, the suction port being spaced from the distal end of the bearing tube;
an inner tube disposed within the bearing tube and having a distal suction opening, the distal suction opening being located proximal of the suction port in the sidewall of the bearing tube;
a solid transition region extending distally from the inner tube and disposed distal to the distal suction opening;
a distal bearing sleeve disposed on the solid transition region extending distally from the inner tube; and
an abrading element disposed distally and supported on the solid transition region.

Abstract
An apparatus for abrading tissue includes a bearing tube having distal and proximal ends, and a suction port formed distally in a sidewall of the bearing tube. An inner tube disposed within the bearing tube has a distal opening, the distal opening being located proximal of the suction port in the sidewall of the bearing tube. A solid transition region extending distally from the inner tube is disposed distal to the distal opening. An abrading element supported distally by the solid transition region is used to perform orthopedic abrading procedures. The outer diameter of the abrading element is greater than the inner diameter of the bearing tube. Debris generated by abrading procedures is aspirated through the suction port formed in the sidewall of the bearing tube and into the lumen of the inner tube. A hooded sheath extends distally from the bearing tube, or optionally from a sheath tube provided over the bearing tube.

12. A method of abrading tissue, comprising:
-
proximating tissue to be abraded with an abrading instrument, the abrading instrument including; a bearing tube having a distal end and a proximal end, and a suction port formed distally in a sidewall of the bearing tube, the suction port being spaced from the distal end of the bearing tube; an inner tube disposed within the bearing tube and having a distal suction opening, the distal suction opening being located proximal to the suction port in the sidewall of the bearing tube; a solid transition region extending distally from the inner tube and disposed distal to the distal suction opening; a distal bearing sleeve disposed on the solid transition region extending distally from the inner tube; a proximal bearing sleeve disposed on the inner tube; and an abrading element disposed distally on the solid transition region; abrading the tissue with the abrading element; and aspirating debris generating by abrading the tissue through the suction port and into the inner tube through the distal suction opening. - View Dependent Claims (13, 14)
