Technical Field

[0001] The utility model belongs to the technical field of scanner positioning, and in particular relates to a positioning device for a pathological slice scanner. Background Art

[0002] The pathological morphological examination method first observes the pathological changes of the gross specimen, then cuts the diseased tissue of a certain size, places the diseased tissue on a glass slide, and then uses a microscope to observe the diseased tissue and examine the lesion.
