[0002] Cancer is a disease that seriously threatens human health and life. If cancer patients can be detected and treated in time at the early stage, not only the survival rate can be improved, but also the quality of life of the patients can be improved. Therefore, cancer must be detected, diagnosed and treated in time. In recent years, the development of optical early diagnosis technology for cancer has included photoacoustic imaging, photoacoustic tomography, photoacoustic spectroscopic microscopy imaging, etc.

[0015] The utility model cooperates with the first placement step, the second placement plate, the slide groove and the slider to place the mouse on the second placement plate for detection during use. When the second placement plate needs to be replaced, the second placement plate only needs to be rotated, and the rotation of the second placement plate will drive the slider to rotate. When the slider rotates to a specified position, the second placement plate can be removed, and then a new second placement plate can be replaced, and then the slider is placed in the slide groove, and then the second placement plate can be rotated to complete the fixation. Through the above design, the second placement plate can be quickly replaced, which improves practicality.
