An ultrasonic probe, having an ultrasonic tip (210) rotatably installed in a housing (100). The rotation axis of the ultrasonic tip (210) is configured along the front-back direction of the probe, thereby ensuring that the ultrasonic tip (210) can rotate about its rotation axis. When an operator uses the probe, the operator would press the front end of the ultrasonic tip (210) against a subject under examination by a certain pre-pressure; the ultrasonic tip (210) automatically rotates and slides to the intercostal area (an area between the ribs) under the pre-pressure, so that the ultrasonic tip (210) would avoid the influence of the ribs. In this case, the operator can still hold the probe in a usual holding position, but because the ultrasonic tip (210) can rotate, the ultrasonic tip (210) can be rotated between the ribs at this time to be in a state parallel to the ribs. Thus, the detection accuracy can be ensured, and the operator does not need to rotate the wrist to adapt to the rotation ...
