Patent ID: 6960894

Claim:
A powered surgical saw, said saw including: a handpiece; a motor disposed in said handpiece for driving a saw-blade in a back-and-forth movement at a variable speed in response to a variable energization signal; a battery connected to said handpiece to provide energization power to said motor; a user-actuated control member movably mounted to said handpiece, said control member being rotatable about an axis between a first orientation and a second orientation, and for each orientation, being displaceable along said axis between an initial position and a final position, with a plurality of user-selected intermediate positions between the initial and final positions, each said position being representative of a user selected motor speed; and a speed limiting assembly configured to limit the speed of said motor so that, when said control member is rotated into said first orientation and displaced to said corresponding final position, said speed limiting assembly causes said motor to run at a first maximum speed, and when said control member is rotated into said second orientation and displaced to said corresponding final position, said speed limiting assembly causes said motor to run at a second maximum speed that is less than said first maximum speed.
