Description

Technical Field

[0001] The utility model relates to the technical field of pathological sample slicing, in particular to a pathological sample detection slicer. Background Art

[0002] Pathology specimen sectioning involves taking a specific size of diseased tissue and preparing it using histopathological methods. Typically, the tissue is embedded in a paraffin block and sliced into thin sections using a microtome. Microscopy is then used to further examine the lesion and its development, ultimately leading to a pathological diagnosis. Before cutting the paraffin block, it must be frozen to cool and harden it for easier sectioning. Paraffin sections are typically measured in microns, so the resulting sections are prone to curling. After sectioning, ophthalmic forceps are typically used to pick up the section and lay it flat on a surface of water. The tension and temperature of the water naturally flatten the curled section, allowing for further microscopic examination. This process is not only time-consuming but also consumes the examiner's attention, impacting the efficiency of pathology specimen sectioning. Summary of the Invention

[0003] In order to overcome the technical problem of curling of paraffin sections, the utility model provides a pathology sample detection slicer.

In addition, the baffle is mounted in the card slot and is pressed into the card slot by tightening the thread of the locking button. The baffle can be removed from the card slot by unscrewing the thread of the locking button, so that the baffle can be frozen before slicing to prevent the temperature of the baffle from being too high, which may cause the slices to return to temperature and become moist.
