[0002] Pathological diagnosis is the "gold standard" for disease diagnosis. It involves processing and observing human tissues or cells obtained through surgical resection, endoscopic biopsy, fine-needle aspiration, etc., to reveal the patterns of disease development and elucidate the nature of the disease. In this process, the pretreatment of pathological specimens is a crucial step in ensuring diagnostic accuracy.

[0003] With the development of precision medicine, the clinical demand for pathological diagnosis is no longer limited to changes in pathological morphology, but increasingly involves molecular-level detection. This requires more standardized and meticulous pretreatment of pathological specimens to ensure the accuracy of subsequent molecular tests. To protect the integrity of the specimens and facilitate observation and diagnosis by pathologists, the obtained specimens need to undergo procedures such as specimen fixation, dehydration, clearing, and paraffin infiltration. Each process requires the use of reagents such as formalin solution, dehydrating agents, clearing agents, and molten paraffin. In traditional specimen pretreatment, operators need to carry the specimens back and forth between different specimen pretreatment laboratories or operating tables. The specimen transfer path is relatively long, resulting in a high risk of cross-infection and affecting the pathological diagnosis results.
