Technical Field

[0001] The utility model relates to the technical field of biological tissue fixing clamps, in particular to a pollution-proof biological tissue fixing clamp. Background Art

[0002] Paraffin section is the most widely used method in routine histological preparation techniques. Paraffin section is not only used to observe the morphological structure of normal cell tissues, but is also the main method used by disciplines such as pathology and forensic medicine to study, observe and judge the morphological changes of cell tissues.

[0003] The paraffin sectioning method includes the steps of sampling, fixation, washing and dehydration, transparency, wax dipping, embedding, slicing and mounting, dewaxing, staining, dehydration, transparency, and sealing. Generally, it takes several days for tissues to be sampled, fixed, sealed, and made into slide specimens, but the specimens can be stored and used for a long time as permanent microscope slide specimens.

[0004] During the wax immersion and embedding process of paraffin-embedded tissue, paraffin easily absorbs and is contaminated with impurities, causing the paraffin blocks used to wrap biological tissues in the experiment to be contaminated with other biological tissues or impurities such as dust, thus causing deviations in the experimental observation results.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and an anti-pollution biological tissue fixing fixture is proposed, in order to achieve a more practical purpose. Utility Model Content
