Abstract
A front end attachment for a powered surgical tool comprises a nose and an irrigation fitting. The nose extends forward from a proximal end of the nose. The nose defines a bore and an enclosed channel. The bore is for receiving a shaft of a cutting accessory connectable to a motor of the powered surgical tool for rotation thereby. The enclosed channel is separate from the bore. The channel extends longitudinally and helically along the nose such that, as the channel extends longitudinally, the channel curves around the nose so as to curve around the bore. The irrigation fitting is in fluid communication with the enclosed channel in the nose. The irrigation fitting is adapted to receive an irrigating fluid and to flow the fluid through the enclosed channel.

A front end attachment for a powered surgical tool, the front end attachment comprising:
- a nose that extends forward from a proximal end of the nose, the nose defining:
- a bore for receiving a shaft of a cutting accessory connectable to a motor of the powered surgical tool for rotation thereby, and
- an enclosed channel separate from the bore, the channel extending longitudinally and helically along the nose such that, as the channel extends longitudinally, the channel curves around the nose so as to curve around the bore;
- and
- an irrigation fitting in fluid communication with the enclosed channel in the nose that is adapted to receive an irrigating fluid and flow the fluid through the enclosed channel.
A front end attachment for a powered surgical tool, the front end attachment comprising:
- a nose that extends forward from a proximal end of the nose, the nose being formed with:
- a first section and a second section with the second section being located distal to the first section and forming a distal end of the nose and the second section being shaped to have a taper such that the second section has a diameter that decreases as the second section extends from the first section,
- a bore extending through the first and second sections with the bore dimensioned to receive a shaft of a cutting accessory that is connectable to a motor of the powered surgical tool for rotation in the bore by the motor,
- an enclosed channel that extends around the first section of the nose with the enclosed channel extending helically along the nose such that, as the channel extends longitudinally along the first section of the nose, the enclosed channel curves around the first section of the nose so as to curve around the bore, and
- an exposed groove formed in an outer surface of the second section of the nose,
- wherein the enclosed channel is in fluid communication with a distal end of the exposed groove;
- and
- an irrigation fitting in fluid communication with the enclosed channel in the nose that is adapted to receive an irrigating fluid so the irrigating fluid may flow through the enclosed channel and be discharged from the groove.
