Abstract:
An abrading instrument for surgically abrading a surface of a skin comprisingan outer member including an outer shaft having an open distal end, an open proximal end and a lumen between said distal and proximal ends; an inner member including an inner shaft having a distal end and a proximal end and an abrading member at said distal end of said inner shaft, said inner member being rotatably disposed within said outer member with said inner shaft disposed in said outer shaft and said abrading member exposed from said outer member, said inner shaft having an aspirating channel therethrough, said abrading member having an abrasive outer surface, and at least one aspirating passage through said abrasive outer surface establishing communication with said aspirating channel from externally of said abrading member, said abrading member being adapted to abrade a surface of the skin contacted by said abrading member while said inner member is rotated relative to said outer member, said aspirating channel being connectible with a source of suction to draw debris generated from abrasion of the skin into said at least one aspirating passage for removal through said aspirating channel; and a shield extending distally from said distal end of said outer member and terminating distally at an open distal shield end, said shield extending alongside said abrading member and partially covering said abrading member to contain the debris generated from abrasion of the skin by said abrading member.
