Abstract

A motorized rotary tool having a drive motor mounted on a distal end of a tubular wand is provided. A drive shaft is operatively coupled to the drive motor and extends along the length of the tubular wand. A head is mounted by a pivotal joint to a proximal end of the tubular wand. The head includes a rotary pad operatively coupled to the flexible drive shaft such that the rotary pad can be driven rotably by the drive shaft. The pivotal joint has a first and a second flexible joint. The first joint is configured to pivot about a first axis which is different from a second axis about which the second joint pivots.
