[0033] It should be noted that the length direction of the sliding rail 210 is parallel to the length direction of the rack 112, so that when the connecting block 220 moves on the sliding rail 210 driven by the moving assembly 230, the compressor 221 can move towards or away from the detector 122, so that the breast tissue of the patient can be pressed between the compressor 221 and the detector 122, facilitating diagnosis.

[0034] In addition, the connecting block 220 and the counterweight 322 are connected together through the two connecting ropes 324, so that the connecting block 220 and the counterweight 322 can move towards each other, so that when the rack 112 rotates to any angle, the counterweight 322 can balance the weight of the connecting block 220 and the compressor 221, so as to prevent the weight of the connecting block 220 and the compressor 221 from affecting the compression strength due to the change of angle, and improve the accuracy of compression.

[0035] Among them, the pressure sensor 310 can be a resistance type pressure sensor, a capacitance type pressure sensor or a piezoelectric type pressure sensor, etc., such as a strain gauge, which will not be described here.

[0036] It can be understood that, with reference to Figure 2 , Figure 4 andFigure 5 The moving assembly 230 comprises a screw rod 231, a sliding block 232, and a driving piece 233. The screw rod 231 is rotationally connected to the rack 112. The sliding block 232 is threadedly connected to the screw rod 231. The sliding block 232 is connected with a guide rod 234. The guide rod 234 is provided with a limiting block 235 at an end away from the sliding block 232. The connecting block 220 is slidingly connected to the guide rod 234, and the connecting block 220 can abut against the limiting block 235.

The sliding block 232 is threadedly connected to the screw rod 231. The guide rod 234 is fixed to the sliding block 232, and the guide rod 234 penetrates through the connecting block 220. The limiting block 235 can abut against the connecting block 220. The driving piece 233 drives the screw rod 231 to rotate, so that the sliding block 232 can move along the axial direction of the screw rod 231, thereby driving the guide rod 234 to axially slide on the connecting block 220, and the limiting block 235 abuts against the connecting block 220, thereby driving the connecting block 220 to slide on the slide rail 210, and facilitating the movement of the connecting block 220.

[0037] It should be noted that the driving piece 233 can be an electric motor, a hydraulic motor, or the like, which can drive the screw rod 231 to rotate, and is not limited herein.

When the pressure sensor 310 abuts against the side wall of the slot 222, the pressure sensor 310 can measure the pressure between the sliding block 232 and the connecting block 220, thereby facilitating the measurement of the compression force of the compressor 221 and improving the accuracy of compression.

[0039] It should be noted that when the screw rod 231 drives the sliding block 232 to move, the limiting block 235 abuts against the connecting block 220, thereby driving the connecting block 220 to move, and the pressure sensor 310 is separated from the side wall of the slot 222. When the compressor 221 contacts the patient, the connecting block 220 remains stationary, and the sliding block 232 continues to move, so that the limiting block 235 moves away from the connecting block 220. Until the pressure sensor 310 contacts the side wall of the slot 222, the sliding block 232 drives the connecting block 220 to continue to move, so that the pressure sensor 310 can measure the pressure between the sliding block 232 and the connecting block 220, thereby avoiding the influence of the friction between the guide rod 234 and the connecting block 220 on the measurement accuracy, and improving the measurement accuracy of the compression force.
