Description

A kind of fully enclosed paraffin block freezing device and using method thereof

technical field

The invention relates to the technical field of pathological examination, and more particularly, to a fully enclosed paraffin block freezing device and a method for using the same.

Background technique

Pathological examination is a kind of detection method to determine the nature of the disease by providing a clear pathological diagnosis basis for clinical through biopsy, exfoliation and fine needle aspiration cytology. Histopathological section is to take human tissue by forceps, through a series of steps such as sampling, fixation, washing, dehydration, transparency, immersion in wax, embedding, sectioning, dewaxing, staining, dehydration, transparency, and sealing, to produce a microscope that can be used for microscopy. To observe the slides of cells, paraffin section (paraffin section) is the most widely used method in the routine preparation technique of histology. Paraffin section is not only used to observe the morphological structure of normal cells and tissues, but also the main method used in pathology and forensic science to study, observe and judge the morphological changes of cell tissues, and has also been widely used in research in many other disciplines. middle.

The core operation steps of histopathological preparation are pathological sections. The quality of the sections directly affects the pathologist's diagnosis of the disease. In addition, the uniqueness and difficulty of obtaining the pathological specimens make the sectioning process particularly critical. Therefore, the quality of the wax block is very important. The quality of the slice is directly determined. The wax block needs to be completely cooled at a temperature below minus 20°C before cutting out 2-3um slices without wrinkles and knife marks.

At present, the wax block needs to be taken out after slicing, but in the actual use process, the phenomenon that the wax blocks stick to each other is easy to occur, which makes the removal of the wax block more troublesome and reduces the number of technicians. work efficiency.

SUMMARY OF THE INVENTION

1. Technical problems to be solved

Before slicing, the wax block will be exposed to room temperature for a long time after it is taken out of the refrigerator. Therefore, in order to avoid the influence of the high temperature of the wax block on the quality of the slice, we need to freeze the wax block. In addition, the existing wax block freezing device is prone to the phenomenon that the wax blocks adhere tightly to each other, and the wax blocks cannot be stored in large quantities, so that the wax blocks can be taken out.
