Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Example 1: as shown in fig. 2 to 3, a probe with adjustable curvature in use specifically includes a sound head assembly including a sound lens 201, a laminate 202, a flexible material sheet a203 and a flexible material sheet b204, a cable assembly and a handle housing 209. In fig. 2, L denotes a distance between the stack 202 and the acoustic lens 201. The laminate 202 includes a matching layer 301, a piezoelectric ceramic 302 and a backing wing 303, wherein the upper surface and the lower surface of the piezoelectric ceramic 302 are plated with gold or silver, and the electrode on the upper surface is conducted with the electrode on the lower surface through a wire. The cable assembly includes a cable 211; the handle shell 209 is filled with a filling liquid 210, and the filling liquid 210 needs to have certain fluidity, has small acoustic loss and good compatibility with the internal structure of the ultrasonic transducer, and can be ultrapure silicon rubber without soda water, olive oil, silicone oil, low acoustic loss and the like. In order to prevent the leakage of the filling liquid 210 from adversely affecting, the handle housing 209 adopts a separate sealing structure.
The acoustic impedance of the filling liquid 210 is 1.2-1.5MRayl, the acoustic impedance of the acoustic lens 201 is consistent with the acoustic impedance of the filling liquid 210 (the difference is within 0.5 MRayl), the short-axis curvature radius of the acoustic lens 201 is determined according to the calculation of the fixed focusing depth, the long-axis curvature radius of the acoustic lens 201 can be determined according to the actual requirement, and the lamination 202 and the acoustic lens 201 can be accurately aligned within the adjustment range of the curvature radius, so that the situation that the edge array element cannot work normally is avoided.

In order to ensure the universality of product design, the curvature radius of the acoustic lens 201 can be set to 63mm, materials with certain hardness and high tightness such as hard silicone rubber, pebax resin, TPX and the like are selected as the materials of the acoustic lens 201, the short axis curvature radius of the acoustic lens 201 needs to be calculated according to the actual design focusing depth, for example, when the focusing depth is 80mm, the short axis curvature radius is 35-50mm, and the specific reference is also made to the specific value of the acoustic impedance of the internal filling liquid 210 and the acoustic lens 201;

When the radius of curvature of the acoustic lens 201 is set to 63mm, if the radius of curvature of the stack 202 is adjusted to 60mm, the distance L between the two is 1-2mm, because the radius of curvature of the stack 202 is calculated based on the radius of curvature of the piezoelectric ceramic 302, the thickness of the matching layer 301 is generally 1-2mm.
In actual operation, if the radius of curvature of the laminate 202 is required to be adjusted from 60mm to 45mm, the length of the precision free telescopic rod 206 at the top end is required to be reduced by 15mm on the original basis, and the precision free telescopic rod 208 at the bottom end is also required to be reduced by 15mm on the original basis, and the laminate 202 and the acoustic lens 201 are still concentric circles, but the distance L between the laminate 202 and the acoustic lens 201 is increased by 15mm, so that the acoustic loss is required to be sufficiently small on the basis of meeting the acoustic impedance requirement, and is generally required to be not more than 0.2dB/mm·mrayl.
