[0025] Please refer to Figures 1 - 3 , the present utility model provides an in vitro diagnostic microsphere lens assembly, including a bracket 1. An object table 9 is fixedly installed on the outer wall of the bracket 1. A high-precision cross slide 10 is arranged on the outer wall of the object table 9. An optical colloid 11 is arranged on the outer wall of the high-precision cross slide 10. A microsphere lens is arranged in the optical colloid 11 to achieve a finer imaging effect. A coarse-precision adjustment slide 2 is fixedly installed on the outer wall of the bracket 1, which is used to realize the preliminary positioning adjustment of the microsphere lens probe assembly 8 within a large range and improve the efficiency of subsequent adjustment. An object table 9 is arranged on the right side of the coarse-precision adjustment slide 2. A medium-precision adjustment slide 3 is fixedly installed on the outer wall of the coarse-precision adjustment slide 2 to further refine the adjustment accuracy and ensure that the microsphere lens probe assembly 8 can approach the target area. A fixed bracket 4 is fixedly installed on the outer wall of the medium-precision adjustment slide 3 to provide a stable support platform for the subsequent precision adjustment system. An installation plate 5 is slidably connected to the outer wall of the fixed bracket 4. A support plate 6 is fixedly installed on the upper side of the installation plate 5. A high-precision adjustment column 7 is fixedly installed on the upper side of the support plate 6, and the lower side of the high-precision adjustment column 7 abuts against the upper side of the fixed bracket 4. The precise height adjustment of the installation plate 5 and its upper components is realized by the expansion and contraction of the adjustment column. A microsphere lens probe assembly 8 is arranged on the outer wall of the installation plate 5.

[0026] Further, the microsphere lens probe assembly 8 includes a circular fixing post 81. One end of the circular fixing post 81 is clamped on the outer wall of the mounting plate 5, and the other end of the circular fixing post 81 is fixedly connected with a fixing block 82, providing a stable foundation for the entire probe assembly. The movable cylinder 84 passes through the fixing block 82 and is rotatably connected to the fixing block 82. Threaded holes 83 are formed on the outer wall of the movable cylinder 84. A plurality of groups of threaded holes 83 are formed on the outer wall of the movable cylinder 84, and the plurality of groups of threaded holes 83 are distributed in a circumferential array around the movable cylinder 84, enhancing the flexibility and adjustability of the connection. The threaded post 85 passes through the fixing block 82 and is threadedly connected to the fixing block 82, for fixing the position of the movable cylinder 84 to ensure the stability after adjustment. A fixing post 86 is fixedly connected to the outer wall of the movable cylinder 84. A fixing post 86 is also fixedly connected to the outer wall of the movable cylinder 84, for connecting subsequent components. One end of the fixing post 86 away from the movable cylinder 84 is hinged to an outer sleeve rod 87, and a telescopic probe 88 is sleeved on the end of the outer sleeve rod 87 away from the fixing post 86. This design enables the telescopic probe 88 to flexibly expand and contract and rotate in three-dimensional space, and can precisely control the rotation and movement of the microsphere lens, thereby realizing a more flexible imaging operation.

[0027] In the present utility model, during use, first, the rough-precision adjustment slide table 2 is used to perform a large-range preliminary positioning on the entire microsphere lens assembly to quickly approach the target area and improve the starting efficiency of subsequent adjustment. Then, the medium-precision adjustment slide table 3 is used to further refine the adjustment of the microsphere lens probe assembly 8 to ensure that the microsphere lens probe assembly 8 can approach the target position more accurately, laying a foundation for precise adjustment. Through the telescopic function of the high-precision adjustment column 7, the height of the mounting plate 5 and the microsphere lens probe assembly 8 is precisely controlled to achieve micron-level vertical displacement adjustment. Rotate the threaded post 85 to make it rotate in the threaded hole 83, thereby fixing or releasing the movable cylinder 84. With the multiple threaded holes 83 distributed in a circumferential array around the movable cylinder 84, different fixing positions can be selected according to needs, increasing the flexibility of adjustment. Through the hinge design of the outer sleeve rod 87 and the fixing post 86, and the telescopic function of the telescopic probe 88, the angle and position of the probe can be flexibly adjusted in three-dimensional space to achieve precise rotation and movement of the microsphere lens.
