1. An ultrasonic probe comprising:

  • (a) an elongate tubular member having proximal and distal ends;

    (b) an imaging ultrasonic transducer pivotally mounted proximate the distal end of said tubular member; and

    (c) cable means for effecting reciprocating pivotal motion of said imaging ultrasonic transducer, comprising;

    a first cable having proximal and distal ends, said first cable being attached at its distal end to said imaging ultrasonic transducer to effect pivoting of said imaging ultrasonic transducer in a first direction when said first cable is pulled;

    a second cable having proximal and distal ends, said second cable being attached at its distal end to said imaging ultrasonic transducer to effect pivoting of said imaging ultrasonic transducer in a second direction when said second cable is pulled;

    a linear motor attached to said first cable for pulling said first cable to effect pivoting of said imaging ultrasonic transducer in the first direction; and

    a tension means attached to said second cable for pulling said second cable when said linear motor ceases pulling said first cable to effect pivoting of said imaging ultrasonic transducer in the second direction.
