Abstract
A cutting accessory ( ) for use with powered surgical tools. The cutting accessory has a hub ( ) for coupling the accessory to the output shaft of a handpiece. A drive shaft ( ) formed of stainless steel or other relatively rigid material extends forward from the hub. A head ( ) formed from nickel titanium alloy or other metal that is more flexible than the material forming the drive shaft is attached to the distal end of the drive shaft. The head is shaped to form the cutting edges of the cutting accessory. In some versions of the invention, intermediate sections ( ) of the drive shaft are formed from the flexible metal or metal alloy.
