Abstract:
1. A device for moving a transducer of an ultrasonic probe, the probe including a case and a transducer for converting an ultrasonic signal into an electric signal, the device comprising: a frame mounted inside the case; a motor mounted to the frame and having a driving shaft; a driven shaft rotatably mounted to the frame; guide rails mounted to the frame for guiding the movement of the transducer; means for transmitting a rotational force of the driving shaft to the driven shaft; and means for transmitting a rotational force of the driven shaft to the transducer to move the transducer along the guide rails, wherein the means for transmitting the rotational force of the driven shaft to the transducer is a wire, and wherein a portion of the wire is wound around the driven shaft and the ends of the wire are fixed to two opposing surfaces of the transducer, wherein a reel having a spiral groove on the peripheral surface is coupled to the driven shaft, and wherein the wire is wound along the spiral groove.
