Background
Pathological examination firstly needs to carry out a series of technical treatments on the cut pathological tissue organs, including fixing, material taking, dehydration, wax dipping, embedding, slicing, staining and the like, and generally takes 24 hours to complete the whole process of making the slices, and the method usually takes 3 days before and after the pathological tissue is cut by a surgeon and pathological diagnosis is made.
