Disclosed is a system for processing a histopathological specimen, which system belongs to the technical field of medical devices. The system for processing a histopathological specimen comprises a movable clamping unit, a dehydration and wax immersion unit (2-1), a slicing unit (3-1), a slide glass dyeing unit (4-1), an image scanning and display unit and a main control unit. By using each of the units above, the series of processing steps, involving fixing, dehydrating, embedding, slicing, rinsing, dyeing and photographing a histopathological specimen after taking materials, can be automatically completed, thereby reducing the workload of skilled persons, preventing the skilled persons from coming into contact with toxic and harmful substances, and shortening the processing time of histopathological specimens.
