Abstract
A power control arrangement for an ultrasonic surgical device such as a scalpel which provides power on demand in response to the continuous or periodic sensing of the loading condition (tissue contact or withdrawal) of the blade such that the device goes from a low power, idle state to a selectable high power, cutting state automatically depending on whether the scalpel is or is not in contact with tissue. A third, high power coagulation mode is manually selectable with automatic return to an idle power level when the blade is not in contact with tissue.
