Paraffin embedding device for tissue positioning and embedding and embedding method thereof

Abstract

The invention relates to a paraffin embedding device for tissue positioning and embedding. The paraffin embedding device comprises an embedding mold and a glue sealing base, wherein the glue sealing base comprises a bottom plate and side plates arranged on the two sides of the bottom plate; a groove penetrating through the bottom plate in the width direction is formed in the part, at one end of the sealing glue base, of the bottom plate; blades with cutting edges exposed out of the bottom plate are fixedly mounted on the inner walls of the two ends of the groove; the side plates at the two ends of the groove are provided with rotating shafts which are transversely arranged on the glue sealing base; elastic pressing sheets are further arranged on the side plate on one side of the upper parts of the rotating shafts; fixing seats are arranged on two side plates at the other end of the sealing glue base; the fixing seats on the two side plates are provided with through holes, supporting shafts transversely arranged on the glue sealing base penetrate through the through holes, the supporting shafts are provided with PET transparent adhesive tapes, the embedding mold is a box body with the top and the bottom hollowed out, the length of the embedding mold is smaller than that of the groove by 5-20 mm, and the width of the embedding mold is equal to that of the bottom plate. The problem that a knee joint cannot be embedded correctly due to the fact that paraffin is solidified too fast in the embedding process of a traditional mold is solved.

Description

technical field [0001] The invention relates to the field of embedding technology, in particular to a paraffin embedding device for tissue positioning embedding and an embedding method thereof, which are used for embedding processing of samples of tissue sections. Background technique [0002] Tissue paraffin sections are widely used in medical research. This technique can not only observe the morphology and structure of normal tissue cells, but also serve as an important reference for judging the morphological changes of cell histology. In the technique of paraffin sectioning, the paraffin embedding of the tissue affects the final section quality, and tissues such as bone tissue, skin tissue, vascular tissue, and uterine tissue that have strict requirements for embedding positions should be especially suitable for embedding. Pay attention to accurately controlling the embedding position. [0003] Taking bone tissue as an example, the observation of animal knee joint tissue...

AI Technical Summary

Problems solved by technology

[0008] Aiming at the deficiencies of the prior art, the present invention provides an easy-to-use paraffin embedding device for tissue positioning embedding, which solves the problem that the traditional mold cannot fully observe the fixed angle of the tissue and the paraffin solidifies too quickly during the embedding process. Improves work efficiency by eliminating problems that could not properly embed the knee joint
