Uterus-passing oviduct ultrasonic detection method, uterus-passing oviduct ultrasonicdiagnosis device and transducer

The invention discloses an uterus-passing oviduct ultrasonic detection method, uterus-passing oviduct ultrasonicdiagnosis device and transducer. The method includes: sending an intra-oviduct ultrasonictransducerwith a center frequency of 10 MHz to 100 MHz to an oviduct part to be testedvia the uterus through an ultra catheter which has a diameter of 0.5 mm to 5 mm; sending to and receiving from the oviduct part to be tested ultrasonic signals at 360 degrees; at the same time withdrawing the ultrasonic energy transducer inside the oviduct. The diagnosis device includes the ultrasonic catheter with the diameter of 0.5 mm to 5 mm. The front end of the ultrasonic catheter is provided with the intra-oviduct ultrasonic energy transducer which has the center frequency of 10 MHz to 100 MHz. The rear end of the ultrasonic catheter is connected to a withdrawing/driving apparatus. The withdrawing/driving apparatus is connected to anelectronic imaging system. The energy transducer includesultrasonic energy transducer units which is composed of a backing layer, a piezoelectric layer and an acoustic matching layer which are successively and tightly connected. According to the invention, the ultrasonic energy transducer to the oviduct part is conducted via the uterus, and imaging resolution is increased,a penetration rate is strengthened, and no blind spots are generated.
