Abstract
A powered surgical tool system. The system includes a handpiece having a motor and a front end attachment removably coupled to the handpiece. The attachment has a nose defining a bore for receiving a shaft of a cutting accessory connectable to a motor of the powered surgical tool for rotation. The nose also defines an enclosed channel separate from the bore. The channel extends longitudinally and helically along the nose such that the enclosed channel curves around the nose to curve around the bore. The channel has a variable pitch as the enclosed channel extends longitudinally. An irrigation fitting is in fluid communication with the enclosed channel in the nose and is adapted to receive an irrigating fluid and flow the fluid through the enclosed channel.

A powered surgical tool system comprising:
- a handpiece having a motor;
- and
- a front end attachment configured to be removably coupled to the handpiece, the front end attachment comprising,
- a nose defining:
- a bore for receiving a shaft of a cutting accessory connectable to a motor of the powered surgical tool system for rotation thereby, and
- an enclosed channel separate from the bore, the enclosed channel extending longitudinally and helically along the nose such that, as the enclosed channel extends longitudinally, the enclosed channel curves around the nose so as to curve around the bore, and the enclosed channel having a variable pitch as the enclosed channel extends longitudinally, 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 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 enclosed channel extending longitudinally and helically along the nose such that, as the enclosed channel extends longitudinally, the enclosed channel curves around the nose so as to curve around the bore, and the enclosed channel having a variable pitch as the enclosed channel extends longitudinally;
- 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.
