Abstract
A surgical tool that includes a nose through which a cutting accessory extends. The nose is formed with an enclosed channel through which irrigating fluid is flowed. The enclosed channel has a helical shape such that as the channel extends longitudinally along the nose, the channel curves around the nose and the cutting accessory disposed in the nose.
Claims20
A powered surgical tool, said tool including:
- a housing that contains a motor for actuating a cutting accessory;
- a nose that extends forward from said housing, the nose being formed with:
- a bore for receiving a shaft of the cutting accessory so that the shaft can be connected to and rotated by the housing motor;
- 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 powered surgical tool, said tool including:
- a housing that contains a motor for actuating a cutting accessory;
- a nose that extends forward from said housing, the nose being formed with:
- first and second sections, the second section being located distal to the first section and forming a distal end of said nose, the second section being shaped to have a taper such that, extending distal from the first section, the second section has a diameter that decreases;
- a bore that extends through the first and second sections, the bore dimensioned to receive a shaft of a cutting accessory that is connected to said motor so as to be rotated in the bore by said motor;
- an enclosed channel that extends around the first section of the nose, 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 has is in fluid communication with a distal end of the 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 fluid flows through the enclosed channel and is discharged from the groove.
