Abstract
A mechanical scan type ultrasonic probe is disclosed, in which a rotational force transmitting shaft for transmitting the rotational force of a motor to an ultrasonic transducer, and a guide pipe for guiding the rotational force transmitting shaft are improved. The guide pipe is a spiral spring. The rotational force transmitting shaft is a highly conductive double spiral spring. Since the guide pipe is constituted by a spiral spring, the pipe can follow any bending movement of the rotational force transmitting shaft to guide the shaft. In addition, since the rotational force transmitting shaft is constituted by a highly conductive double spiral spring, it can properly supply and extract electrical signals to and from an ultrasonic transducer, and can properly transmit the rotational force to the transducer.
