Detailed Description
The following describes embodiments of the present invention in detail with reference to the accompanying drawings.
Example 1: as shown in fig. 2 to 3, a curvature-adjustable probe in use specifically includes a sound head assembly, a cable assembly and a handle housing 209, where the sound head assembly includes an acoustic lens 201, a laminate 202, a flexible material sheet a203 and a flexible material sheet b 204. In fig. 2, L denotes a distance between the stack 202 and the acoustic lens 201. The stack 202 includes a matching layer 301, a piezoelectric ceramic 302 and a backing wing 303 stacked on top of each other, the upper surface and the lower surface of the piezoelectric ceramic 302 are both plated with gold or silver, and the electrodes on the upper surface and the electrodes on the lower surface are connected through wires. The cable line assembly comprises a cable line 211; the handle shell 209 is filled with filling liquid 210, and the filling liquid 210 is required to have certain fluidity, have small sound loss and good compatibility with the internal structure of the ultrasonic transducer, and can be ultrapure silicon rubber without steam water, olive oil, silicon oil, low-sound-loss silicon rubber and the like. In order to prevent the filling liquid 210 from leaking out and causing an adverse effect, the handle case 209 described above employs 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 that of the internal 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 fixed focusing depth calculation, and the long-axis curvature radius of the acoustic lens 201 can be determined according to the actual requirement, so that the stack 202 and the acoustic lens 201 can be accurately aligned within the adjustment range of the curvature radius, and the situation that the edge array element cannot normally work is avoided.
The curvature radius adjustment of the laminate 202 may be fixed, such as by a predetermined procedure of setting several common curvature radii, such as 45mm, 50mm, 55mm, and 60 mm; the curvature radius can be adjusted steplessly, and the curvature radius can be controlled accurately according to a program, for example, any curvature radius in the middle of (45-60) mm can be adjusted in place.
In order to ensure the universality of product design, the curvature radius of the acoustic lens 201 can be set to 63mm, the acoustic lens 201 is made of materials with certain hardness and strong sealing property, such as hard silicone rubber, pebax resin, TPX and the like, the curvature radius of the short shaft of the acoustic lens 201 needs to be calculated according to the actual designed focusing depth, for example, when the focusing depth is 80mm, the curvature radius of the short shaft is 35-50mm, and the specific value of the acoustic impedance of the internal filling liquid 210 and the acoustic lens 201 is specifically referred to;
the acoustic lens 201 and the handle shell 209 need to be bonded and fixed through sealing glue, and the bonding force needs to be capable of enduring a certain temperature range, generally needs to be-34-65 ℃, namely, the problem of poor sealing performance cannot occur in the temperature range.
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 therebetween is 1-2mm, and since 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 1-2 mm.
In actual operation, if the radius of curvature of the stack 202 needs to be adjusted from 60mm to 45mm, the length of the top end precision free telescopic rod 206 needs to be adjusted to be reduced by 15mm on the original basis, and the length of the bottom end precision free telescopic rod 208 needs to be reduced by 15mm on the basis, at this time, the stack 202 and the acoustic lens 201 are still concentric circles, but the distance L between the stack 202 and the acoustic lens 201 is increased by 15mm, so that the acoustic loss is small enough on the basis that the acoustic impedance requirement is met by the liquid 210 filled in the handle shell, and generally not more than 0.2dB/mm · MRayl is required.
In order to solve the technical problem that the probe is frequently replaced in different application scenarios, the curvature-adjustable probe in this embodiment further includes an adjusting device for adjusting the curvature of the acoustic head assembly, the adjusting device includes a top gimbal fixed joint 205, a top precise automatic telescopic rod 206, a bottom gimbal fixed joint 207, and a bottom precise automatic telescopic rod 208, the top gimbal fixed joint 205 is connected to the flexible material sheet b204, the top precise automatic telescopic rod 206 is connected between the top gimbal fixed joint 205 and the bottom gimbal fixed joint 207, and the bottom precise automatic telescopic rod 208 is connected to the bottom gimbal fixed joint 207. The number of the top end precision automatic telescopic rods 206 is plural, and the number of the top end universal joint fixing joints 205 is adapted to the number of the top end precision automatic telescopic rods 206. The bottom end precision automatic telescopic rod 208 is fixed at the center of the bottom of the handle housing 209, the curvature radius of the stack 202 is adjusted to a desired size, for example, 50mm, by adjusting the length of the top end free telescopic rod 206, and then the length of the bottom end precision automatic telescopic rod 208 is adjusted to ensure that the center of the stack 202 coincides with the center of the acoustic lens 201.
The flexible material sheet a203 is made of a magnetic material, and can be made of a material with certain magnetism, wherein the material can be a material with magnetism, such as iron, cobalt, nickel, ferroferric oxide, ferrite and the like, or a composite material containing the material, such as powder with the magnetism and epoxy resin which are mixed according to a certain percentage;

The flexible material sheet a203 and the flexible material sheet b204 fix the lamination 202 through magnetic force to help later maintenance, namely if the quality problem (such as array element damage, line aging and the like) of the product is found in later period, the probe can be directly disassembled to replace the lamination 202 with qualified products for encapsulation and use again, and the cost of the probe using unit can be effectively saved in the long-term use process.
