Ultrasonic disintegrator for calculi - has piezoelectric transducer coupled to cystoscope between different metal discs

摘要

Ultrasonic disintegrator for cystic, urethral and renal calculi has a piezoelectric transducer with 2 piezoelectric discs between a steel and an A1 body in connection with a cystoscope. The transducer is connected to a fastening yoke carrying the coupling cone for connection of the shaft, and levers outside the action of the vibrations. The end of the sound transmission element can be passed at an angle of up to 45 deg. through the cone. The auxiliaries are outside the vibration field and suited to the patient's anatomy, to give optimal observation conditions for the doctor.
