Abstract

The invention discloses an ultrasonic scanning probe. In the probe, a transmission mode that a worm and a gear are matched with each other is adopted, which has larger transmission rate and higher transmission efficiency, so that the swing torque of a transducer is correspondingly enlarged, the scanning effect is better, and the working efficiency is higher. Meanwhile, the assembly volume of the worm and the gear is smaller, and power transmission of the ultrasonic scanning probe can be completed only by virtue of mutual matching of the worm and the gear, so that the whole assembly volume of the ultrasonic scanning probe can be correspondingly reduced.
