Technical Field

[0001] The utility model relates to the technical field of imaging devices, in particular to a fluorescent molecule imaging device. Background Art

[0002] Compared with traditional medical imaging technology, molecular imaging focuses on the basic changes and abnormalities at the gene molecular level that constitute diseases or lesions, rather than imaging the final results of gene molecular changes. With the help of specific molecular probes, molecular imaging technology can achieve non-invasive real-time dynamic in vivo imaging of physiological or pathological processes within organisms at the cellular, genetic and molecular levels, thereby providing detailed qualitative, positioning, and quantitative data as well as effective means of information acquisition and analysis for the localization of disease-related gene functions, the mechanism of cell growth and development and mutation processes, and new drug development.

[0003] Currently, when using fluorescent molecular imaging devices, in order to prevent blurred images such as spots, the emitting part needs to be frequently inspected and maintained. However, fluorescent molecular imaging devices are mostly installed with threads, which makes disassembly inconvenient. Frequent disassembly and rotation of the threaded parts can easily cause the joints to loosen, affecting the stability of the installation. Utility Model Content
