This invention discloses an ultrasonic probe and ultrasonic diagnostic device, including a
handle, a shaft, and a head end. The shaft is located between the
handle and the head end, positioning the head end at a predetermined distance away from the
handle. The device also includes: a drive mechanism located within the handle for outputting driving force; a
bevel gear transmission mechanism located within the head end and connected to the drive mechanism; and an ultrasonic
transducer located within the head end and connected to the
bevel gear transmission mechanism, so that when the drive mechanism is operating, the
bevel gear transmission mechanism drives the ultrasonic
transducer to oscillate. The drive mechanism drives the ultrasonic
transducer to oscillate via the bevel
gear transmission mechanism. The bevel
gear transmission mechanism achieves motion transmission through the meshing of the driving and driven bevel gears, resulting in
high transmission accuracy, small transmission backlash, and stable transmission. Therefore, the ultrasonic transducer exhibits
high motion accuracy, ensuring the
image quality obtained by the ultrasonic transducer.
