Double-curved-surface strip-shaped power ultrasonic device with linear mobile imaging probe

Abstract

The invention discloses a hyperboloid strip-shaped power ultrasonic device with a linearly moving imaging probe, which includes an ultrasonic focusing transducer, a supporting structure, a water bladder and an ultrasonic imaging probe, and the ultrasonic focusing transducer is symmetrical through silicon rubber. Sealed on the left and right sides of the supporting structure, the surrounding of the supporting structure is provided with a water bag as a waterproof all-inclusive structure, the gap between the water bag and the supporting structure is filled with coupling agent, the upper part of the supporting structure The surface is an arc-shaped hyperboloid, and a square through hole is arranged at the center of the supporting structure, and the ultrasonic imaging probe is placed in the through hole. The transducer of the present invention scans into a plane, the focus area is concentrated, and the treatment plane and the imaging plane of the imaging probe are just on the same plane; at the same time, the distance between the imaging probe and the patient's body is relatively close in the present invention, which is conducive to ultrasonic imaging and can improve the treatment process. image clarity.

Description

technical field [0001] The invention relates to a hyperboloid strip power ultrasonic device with a linearly moving imaging probe, which belongs to the technical field of medical equipment. Background technique [0002] The application of power ultrasound in the medical field, a common way is to transmit focused power ultrasound from the outside of the human body to the inside of the human body, forming a large energy accumulation in a specific area of ​​the human body to change the biological characteristics of the tissue in the area, and to achieve the purpose of treating diseases . Among them, the ultrasonic transducer is used to convert electrical energy into sound energy and emit it into the human body. Currently, commonly used ultrasonic transducers generally adopt the form of a single transducer, multiple transducer arrays, or hundreds of transducer arrays. . Regardless of the method, the shape of the spherical crown is basically adopted, and a through hole is provid...

Problems solved by technology

Transducers of these shapes can achieve 360-degree omnidirectional deflection when the phased array control circuit is used for electronic deflection of the sound beam, but because of their relatively large size in each direction, according to the general principle of acoustics, they can be used in The deflectable angle in each direction is relatively small, which affects practicality
