[0027] This invention provides an adjustment structure for a photoacoustic imaging probe, which aims to solve the problem that existing photoacoustic imaging probes often lack flexible and precise adjustment structures in actual use, thus failing to quickly adjust the direction and angle, making it difficult to meet the needs of different detection scenarios and parts, and indirectly limiting the further application of photoacoustic imaging technology.

[0028] like Figures 1-5 As shown, the present invention provides an adjustment structure for a photoacoustic imaging probe, including a mounting plate 1, a rotating structure 2 at the bottom of the mounting plate 1, a suspension plate 3 bolted to the bottom of the rotating structure 2, an adjustment structure 4 inside the suspension plate 3, an angle adjustment mechanism 5 at the bottom of the adjustment structure 4, and a photoacoustic imaging probe 6 at the bottom of the angle adjustment mechanism 5.

[0029] The angle adjustment mechanism 5 includes a bracket 501 bolted to the bottom of the adjustment structure 4. A fixing sleeve 502 is fixedly connected to the bottom front side of the bracket 501. An electric push rod 503 is rotatably connected inside the fixing sleeve 502. A rotating rod 504 is rotatably connected to the front inside the bracket 501. The top side inside the rotating rod 504 is rotatably connected to the telescopic end of the electric push rod 503. A connecting block 505 is fixedly connected to the top of the photoacoustic imaging probe 6. The top of the connecting block 505 is bolted to the bottom side inside the rotating rod 504.

[0030] In the technical solution of this utility model, by setting up a rotating structure 2, a suspension plate 3, an adjusting structure 4, an angle adjusting mechanism 5, and a photoacoustic imaging probe 6, the rotating structure 2 at the bottom of the mounting plate 1 can drive the suspension plate 3, the adjusting structure 4, the angle adjusting mechanism 5, and the photoacoustic imaging probe 6 to rotate in the horizontal direction. This design allows the photoacoustic imaging probe 6 to quickly adjust its orientation to adapt to different detection scenarios. Furthermore, the adjusting structure 4 on the suspension plate 3 can adjust the lateral position of the photoacoustic imaging probe 6. Simultaneously, combined with the rotating structure 2, longitudinal and oblique position adjustments can also be achieved. For example, when detecting a certain area of ​​the body, this coordinated adjustment... The photoacoustic imaging probe 6 can be precisely aligned with the target area without moving the entire device. Meanwhile, the bracket 501 in the angle adjustment mechanism 5 provides stable support for the entire mechanism. When the electric push rod 503, which is rotatably connected inside the fixed sleeve 502, extends or retracts, it drives the rotating rod 504 on the front side inside the bracket 501 to rotate. The connecting block 505 on the top of the photoacoustic imaging probe 6 is bolted to the bottom side inside the rotating rod 504. Therefore, the rotation of the rotating rod 504 will change the detection angle of the photoacoustic imaging probe 6. This design meets the needs of different detection parts. For some parts that are difficult to align directly, better imaging effect can be obtained by adjusting the angle of the photoacoustic imaging probe 6.

[0031] Please refer to the following: Figure 2 The rotating structure 2 includes a fixing block 201 fixedly connected to the bottom of the mounting plate 1. A servo motor 202 is bolted to the bottom of the fixing block 201. A shaft 203 is bolted to the output end of the servo motor 202. A rotating disk 204 is bolted to the bottom of the shaft 203. The bottom of the rotating disk 204 is bolted to the top of the suspension plate 3. In this embodiment, by setting the rotating structure 2, the shaft 203 is driven to rotate by the servo motor 202, which in turn drives the rotating disk 204 to rotate. This allows the suspension plate 3, the positioning structure 4, the angle adjustment mechanism 5, and the photoacoustic imaging probe 6 to rotate in the horizontal direction. This facilitates quick adjustment of the orientation to adapt to different detection scenarios. For example, when detecting different parts of the body, the photoacoustic imaging probe 6 can be aligned with the target area without moving the entire device, thus improving detection efficiency.

[0032] For further information, please continue to refer to [link / reference]. Figure 3The adjustment structure 4 includes a reciprocating motor 401 bolted to the left side of the suspension plate 3.

The right side of the lead screw 402 is rotatably connected to the right side inside the suspension plate 3, and an adjustment plate 403 is threadedly connected to the outside of the lead screw 402. The adjustment plate 403 is slidably connected inside the suspension plate 3, and the bottom of the adjustment plate 403 is bolted to the top of the bracket 501. In this embodiment, by setting the adjustment structure 4, the lead screw 402 is driven to rotate by the reciprocating motor 401, causing the adjustment plate 403 to move laterally inside the suspension plate 3, thereby adjusting the lateral position of the photoacoustic imaging probe 6. Furthermore, in combination with the rotation structure 2, the longitudinal and oblique positions of the photoacoustic imaging probe 6 can also be adjusted. For example, when detecting a certain area of ​​the body, this coordinated adjustment allows the photoacoustic imaging probe 6 to be accurately aligned with the target area without moving the entire device.

[0034] Please refer to Figure 5 A protective shell 8 is bolted to the left side of the suspension plate 3, and the protective shell 8 is located outside the reciprocating motor 401. In this embodiment, by setting the protective shell 8, the reciprocating motor 401 can be protected to ensure its normal operation during use.

[0035] Additionally, please refer to Figure 5 A shielding mesh 9 is bolted to the left side of the protective shell 8, and the shielding mesh 9 is located on the left side of the reciprocating motor 401. In this embodiment, by setting the shielding mesh 9, the shielding mesh 9 further protects the reciprocating motor 401 on the basis of the protective shell 8 protecting it, while not affecting the heat dissipation of the reciprocating motor 401 during operation.
