Abstract
An instrument sleeve is provided for use with a surgical rotary instrument having a tube extending to a distal tube end, and a cutting accessory having a head and a shank extending from the head adapted to be rotatably supported by the tube of the rotary instrument. The instrument sleeve comprises a sleeve body extending between proximal and distal sleeve portions, a first lumen for receiving at least a portion of the tube of the rotary instrument, and a shield extension coupled to the sleeve body. The shield extension extends between proximal and distal shield portions the proximal shield portion engaged with the distal sleeve portion and adapted to minimize tissue wrap about the cutting accessory shank.

An irrigation sleeve for use with a surgical system comprising an irrigation source, a rotary instrument having a tube extending to a distal tube end, and a cutting accessory having a head and a shank adapted to be rotatably supported by the tube of the rotary instrument, the irrigation sleeve comprising:
- a sleeve body extending between a proximal body portion and a distal body portion;
- a first lumen formed in said sleeve body for receiving at least a portion of the tube of the rotary instrument;
- a second lumen formed in said sleeve body and spaced out of fluid communication with said first lumen;
- a shield extension coupled to said sleeve body and having a proximal shield portion and a distal shield portion, said proximal shield portion engaged with said distal body portion, said shield extension adapted to minimize tissue wrap about the cutting accessory shank;
- and
- a third lumen formed in said shield extension and in communication with said first lumen;
- wherein said shield extension further comprises a pilot member coupled to said proximal shield portion and at least partially disposed in said first lumen;
- and
- wherein said first lumen defines a first lumen diameter, said third lumen defines a third lumen diameter, and said pilot member defines a pilot diameter, said pilot diameter being greater than said third lumen diameter and less than said first lumen diameter.
