Abstract
A pistol-shaped surgical handpiece comprises a pistol-shaped housing including a forward/rearward extending barrel and a handle fixedly depending from the barrel. A motor and control circuit are supported in the barrel. The motor drives a tool carrier at the front end of the barrel. In one preferred embodiment, the housing is of formed sheet metal and the motor, control unit and a drive train for driving the tool carrier, are mounted as a sealed unitary cartridge within the sheet metal barrel. In one embodiment, the battery is inserted upward into the bottom of the handle and telescopes therein for a substantial distance to permit a relatively compact handle arrangement while yet permitting a full size handle rigidly joined to the barrel of the housing.
