Linear scanning mechanical volume probe

A linear scanning mechanical volume probe, comprising:

• a bracket;
• a drive wheel rotatably mounted on the bracket;
• a first reverse wheel rotatably mounted on the bracket, an axis of the first reverse wheel being parallel to an axis of the drive wheel;
• a second reverse wheel rotatably mounted on the bracket, the axis of the second reverse wheel being parallel to the axis of the drive wheel;
• a drive member fixedly connected to the bracket, and an output shaft of the drive member being coaxial with and fixedly connected to the drive wheel;
• a guide rod fixedly connected to the bracket, wherein an axis of the guide rod is perpendicular to an axis of the drive wheel, and the first reverse wheel and the second reverse wheel are respectively provided near opposite ends of the guide rod;
• a slider axially slidable along the guide rod;
• a transducer fixedly connected to the slider;
• a first rope having two ends of the first rope respectively connected to the drive wheel and the slider, and the first rope being wound on the first reverse wheel;
• a second rope, wherein two ends of the second rope are respectively connected to the drive wheel and the slider, and the second rope is wound on the second reverse wheel;
• the first rope and the second rope are wound on the drive wheel in opposite directions, and the winding direction of the first rope on the first reverse wheel is opposite to the winding direction of the second rope on the second reverse wheel;
• and
• at least one elastic member connected to the drive wheel or the slider, at least one end of at least one rope being in buffer connection to the drive wheel or the slider via the elastic member.
