Abstract
Herein disclosed is an ultrasonic probe comprising a transducer for transducing an electric signal into and out of an ultrasonic wave, an electromagnet motor for rotating the transducer, a frame structure for rotatably supporting the electromagnet motor, a brake mechanism for allowing the electromagnet motor to be braked. The ultrasonic probe thus constructed can actuate the brake mechanism to brake the electromagnet motor to prevent the transducer from rotating when the electromagnet motor is stopped and release the brake mechanism to enable the transducer to rotate when the electromagnet motor is rotating, thereby protecting the transducer from a large shock caused by the electromagnet motor especially when the ultrasonic probe is dropped.
