PURPOSE:To provide an ultrasonic diagnostic system capable of smoothly and accurately transmitting rotational torque from a driving motor to a rotor even when an ultrasonic wave probe curves or meanders and improved in measuring accuracy without generating the distortion of an image to rotational nonuniformity. CONSTITUTION:This ultrasonic diagnostic system is provided with the ultrasonic wave probe 1 and a system main body 2. The ultrasonic wave probe 1 consists of an insertion part 3 (which contains at least the rotor 14 equipped with a vibrator 11) and a manual operating part 4. The manual operating part 4 includes a rotation sliding mechanism 22 connected to the output shaft of the driving motor 21. The rotation sliding mechanism 22 is provided with a ball spline type bearing device 26 connected to a sleeve shaft 25. The ball spline type bearing device 26 consists of an outer peripheral housing 27 and a slide shaft 28 inserted to the housing slidably in an axial direction. A flexible shaft 7 is connected rotatably to the insertion part 3 side of the slide shaft 28. The other terminal of the flexible shaft 7 is connected to the rotor 13. |
