1. An ultrasonic probe, comprising:
an ultrasonic transducer array configured to transmit and receive ultrasonic waves;
a conducting device disposed at a front end of the ultrasonic transducer array, wherein the conducting device comprises a fluid chamber filled with liquid, and the fluid chamber has an opening and an energy receiving port which are in communication with each other, and the opening is disposed on a front surface of the conducting device and covered by an elastic film; and
an energy applying device, connected to the energy receiving port and configured to apply vibrations to the liquid within the fluid chamber,
wherein the energy receiving port is configured to receive the vibrations, the vibrations received by the energy receiving port reaches the elastic film after being transferred via the liquid in the fluid chamber, and causes the elastic film to vibrate and generate a shear wave propagating from a body surface to an inside of a tissue, and the ultrasonic waves are utilized to trace the propagation of the shear wave inside the tissue, so as to perform instantaneous elastography and acquire at least one of elasticity information and attenuation information of the tissue,
wherein the conducting device further comprises an acoustic lens, the acoustic lens is connected to the front end of the ultrasonic transducer array, and the acoustic lens surrounds the fluid chamber from side surface of the fluid chamber;
wherein a first portion of the ultrasonic transducer array corresponding to a projection of the fluid chamber is configured to receive an ultrasonic signal including shear wave information.
