Description

Technical Field

[0001] This utility model belongs to the field of embedding box technology and relates to a pathological tissue embedding box. Background Technology

[0002] Tissue sampling, embedding, and paraffin sectioning are the most basic tasks in the pathology departments of hospitals, and tissue embedding cassettes play a very important role in these three tasks.

[0003] Currently, major laboratories primarily use various tissue embedding cassettes, including those for gastrointestinal endoscopy, small-well, and large-well procedures. In practical applications, gastrointestinal endoscopy tissue embedding cassettes are generally only used for collecting small tissue samples from endoscopy or biopsies. In practice, there may be an excessive number of samples, with large and small samples mixed together, making it difficult to meet all requirements during pre-preparation.

[0004] Large-pore pathological tissue embedding cassettes are the most commonly used type in pathology departments of major hospitals. Due to their larger pores, they facilitate the dehydration of most pathological tissue specimens. However, when dealing with smaller pathological tissue specimens, such as those obtained through colposcopy biopsy, the specimens are prone to leakage and loss through the pores. To address this issue, most hospital pathology departments choose to wrap small tissue specimens with embedding paper and place them in embedding cassettes for dehydration. However, in actual embedding processes, it has been found that some specimens containing mucus adhere to the embedding paper, and are extremely difficult to distinguish due to the interference of paraffin. Furthermore, most embedding papers exhibit varying degrees of shedding, causing some difficulties for subsequent microscopic observation.

[0005] Small-pore pathological tissue embedding cassettes have solved the problems of tissue loss and adhesion to the embedding paper for small specimens to some extent. However, they present certain problems when used with larger tissue specimens. Large tissue specimens may not be sufficiently fixed or dehydrated during fixation and dehydration, which can cause problems for subsequent sectioning. Secondly, during the embedding process, the small pores of the embedding cassette make it difficult for liquid paraffin to pass through, reducing overall work efficiency. In the later stages, the paraffin block may develop voids and air bubbles, making it easy for the paraffin to detach from the embedding cassette during sectioning. This results in limitations such as the need for re-embedding of larger tissues and the easy loss of smaller tissues. Utility Model Content
