Abstract
A surgical tool designed for irrigated microsurgery or pediatric surgery. The tool includes an outer hub that is fixed to a complementary handpiece. An outer tube extends forward from the outer hub. An inner hub is coupled to a drive member integral with the handpiece to rotate in unison with the drive member. An inner tube extends forward from the inner hub and is disposed inside the outer tube. A cutting member is located on the forward end of the inner tube. The inner wall of the outer tube and the adjacent outer wall of the inner tube are in close proximity to each other. Irrigation fluid is introduced between the tubes through an opening in the outer hub. The outer wall of the inner tube is formed with a flat that extends longitudinally along the tube from the section of the inner tube that is subtended by the opening for the irrigation fluid to the distal end at which the cutting assembly is located. The flat defines a channel between the tubes through which the irrigation fluid flows from the opening to the cutting assembly. A suction from the surgical site is drawn through the center of the inner tube and the inner hub.
