Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic probes, and more specifically to a rotating scanning imaging probe. Background Art

[0002] An ultrasonic probe is a device that uses piezoelectric chips to transmit and receive ultrasonic waves, and mainly uses the piezoelectric effect of the material to achieve electrical energy and sound energy conversion.

[0003] In the prior art, a Chinese utility model with a publication number of CN219422847U discloses an ultrasonic probe transducer, including a metal sheath, a first transducer, and a second transducer. The metal sheath is provided with a first installation window and a second installation window. The first transducer and the second transducer are assembled with the metal sheath. The transmitting end of the first transducer corresponds to the first installation window, and the transmitting end of the second transducer corresponds to the second installation window.

[0004] When the above-mentioned ultrasound probe transducer is in use, the transducer cannot move forward and backward or rotate, so it is inconvenient to use and the imaging angle is insufficient, which affects the imaging effect. For example, when used in the treatment of prostate diseases, after the ultrasound probe is inserted into the rectum, the transducer cannot image and locate part of the treatment area, and the transducer can only be rotated by rotating the ultrasound probe, which is inconvenient to use.

[0005] Therefore, it is necessary to propose a new solution to solve the above problems. Utility Model Content
