Problems solved by technology
[0003] The disadvantage of the prior art is that the focal point of the transducer used in the existing ultrasonic therapy system can be adjusted in a small range, and a single array element has only one natural focal point, and can only be moved mechanically to obtain different positions. The depth of focus is fixed, and the focus at different depths cannot be obtained
For multi-element curved surface transducers, the phase delay of each transducer element can be changed to change the focus position, but the structure is complex, and because all the elements are embedded in a curved surface, the adjustable range becomes smaller
[0004] For example, Chinese patent CN201420005074.X discloses the main structure of the ultrasonic transducer, which does not mention how to adjust the focal position of the curved surface transducer in three-dimensional space

The invention relates to the technical field of ultrasonic treatment, in particular to a focus-adjustable curved surface ultrasonic transducer and an ultrasonic treatment system. The focus-adjustablecurved-surface ultrasonic transducer comprises a curved-surface transducer and a focal length adjusting unit arranged above the curved-surface transducer. The focal length adjusting unit comprises a focal length adjusting unit frame and a liquid container fixed in the focal length adjusting unit frame, and the liquid container is arranged above a sound beam path emitted by the curved surface transducer. According to the invention, the focal length adjusting unit is designed to adjust the focusing area of the HIFU curved surface transducer in a three-dimensional space. Compared with an existingHIFU curved surface transducer, the focal region position is adjustable, and suitable for all existing HIFU curved surface transducers. The part is independent of the HIFU curved surface transducer,the design is simple, the installation is simple, the arrangement of the focal length adjusting unit can be adjusted according to the requirements, and different focusing positions can be obtained.
Description
technical field [0001] The invention relates to the technical field of ultrasonic therapy, and more particularly, to a curved-surface ultrasonic transducer with adjustable focus and an ultrasonic therapeutic system. Background technique [0002] Ultrasound therapy technology is to use the penetrating and focusing properties of ultrasound to focus the external ultrasound on the target area in the body, and the focus will generate high temperature, causing high-temperature coagulation necrosis of the tissue in the target area, and the tissue outside the target area will not be traumatized. The purpose of target tissue ablation. Most of the existing ultrasonic therapy systems use curved surface single-array or phased-array multi-array transducers, which have a natural focus, and the focus position is changed by mechanical movement to form a large treatment area. [0003] The disadvantage of the prior art is that the focal point of the transducer used in the existing ultrasonic...
