Abstract
A surgical cutting device having a powered handpiece adapted to receive a cutting blade. The cutting blade is locked to the drive shaft by a locking ball holding member which is locked in place by a cylindrical cam ring which urges the balls of the locking device into corresponding notches in the blade. A second locking ball holding member is provided on the housing of the handpiece to lock the cylindrical cam ring itself. A blade guard extends from the cylindrical cam ring to produce a surgical cutting device having an improved safety feature which prevents its operation without the guard in proper position.
