AN ULTRASONIC THERAPY INSTRUMENT FOR PREVENTING EARLY PREGNANCY

摘要

An ultrasonic therapy instrument for preventing early pregnancy comprises a three-dimensional servo unit firmed on a stand, a B-mode ultrasonic diagnostic device and a transducer assembly. The three-dimensional servo unit is localized by an electromagnetic locking means. A three-arm fork is provided on the vertical sliding shaft of the three-dimensional servo unit. A horizontal rotating shaft is mounted on one arm of the three-arm fork, and the B-mode ultrasonic diagnostic transducer is provided on the horizontal rotating shaft. A plane wave ultrasonic transducer and a focused wave ultrasonic transducer are mounted on the remainder two arms o f the fork respectively.
