When the examination is over, we need to press the freeze button to end the mechanical vibration of the piezoelectric crystals, so as to protect the ultrasound probe. At present, the placement of the ultrasonic probe is that the front of the probe is placed upwards in the groove next to the operating table of the ultrasonic machine. At this time, even if the ultrasonic probe is working, the ultrasonic waves emitted by the contacting air are almost completely reflected back, and it is not close to the screen of the ultrasonic machine. Observation is difficult to find subtle ultrasonic echoes, so forgetting to press the freeze button will make the piezoelectric crystal work for a long time, causing unnecessary damage to the piezoelectric crystal.

However, the existing devices for protecting the piezoelectric crystals of ultrasonic probes are generally inconvenient to fix and have poor stability. Some use alligator clips to fix them. There is no positioning for the alligator clip, and the fixation is not stable.
