Abstract
During extension, the reamer block of an expandable reamer pushes on an upper plate. Extension is limited by contact with a spring retainer. To adjust the maximum extension of the expandable reamer, a spacer is placed between the expandable block and the spring retainer. The spacer reduces the amount of longitudinal travel of the expandable reamer, thereby reducing the extension of the expandable reamer.
