Abstract
An ultrasonic surgical scalpel comprising a suction nozzle having a suction mouth which is open aside toward the direction different from that of the axis of the nozzle, and a suction regulating mouth formed in a suction pipe extending from the suction nozzle so as to communicate with a suction passage inside the suction nozzle. The suction mouth being open aside allows the leading end of the nozzle to be mad acute or round, thereby to enable the suction nozzle to be readily inserted and moved in subcutaneous or organic tissues while shattering the tissues with ultrasonic vibrations. When sucking out the tissues shattered with the vibrations, by selectively opening and closing the suction regulating mouth with a finger tip, sucking force for sucking out the tissues can be freely controlled with ease.
