Embodiment

[0058] The following provides an implementation example for the production of the two-dimensional coding column: through the principle similar to the three-dimensional printer, the muscle tissue material composed of protein and the nucleic acid material are respectively stacked into long columnar shapes with different thicknesses, so that the cross section of the coding column 80 has a two-dimensional shape. Code encoding rules. The coding column 80 is processed together with the sample, and finally the completed section can be stained with hematoxylin-eosin. In the coding column 80, the muscle tissue material composed of protein will be stained pink, while the nucleic acid material will be stained dark purple. All the information of the tissue section 90 can be obtained through the automatic identification of the light microscope and the computer.

[0059] Furthermore, in the present invention, under the condition that the lower part of the tissue positioning bracket (612, 6...

Abstract

The invention provides an automatic treatment device and method for tissue sample dehydration and embedding. The device comprises a three-dimensional moving device, a rotary driving device, a disc container, a multi-groove liquid changing workbench and a tissue embedding mold box assembly. The tissue embedding mold box assembly comprises an embedding mold box upper cover, an embedding mold box anda tissue positioning support located between the embedding mold box upper cover and the embedding mold box. The tissue positioning support is used for seamlessly attaching biological tissue to the bottom of the embedding mold box. The disc container is used for accommodating at least one tissue embedding mold box assembly; the multi-groove liquid changing workbench comprises at least one container containing molten embedded wax liquid. The three-dimensional moving device is used for driving the disc container to move up and down in each container; and the rotary driving device is used for driving the disc container to rotate in the container. The whole process is automatically carried out, and compared with the prior art, samples do not need to be manually transferred among several different machines, so that the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of automatic detection of biomedical pathological tissues, in particular to an automatic processing device and method for tissue sample dehydration and embedding. Background technique [0002] In pathological diagnosis, it involves fixation, dehydration, embedding, sectioning and sample labeling of biopsy tissue. Obviously, this is tedious work. For example, for the labeling of samples, each tissue section must have a label to indicate who is the sample under what circumstances. Once the label is wrong, it will lead to mistakes. As another example, conventional tissue dehydration is carried out in an empty box, which is then manually positioned with wax on the bottom of the embedding box. [0003] American Cherry Blossom Inspection Instrument Co., Ltd. proposed a method of positioning and fixing sample tissue in a soft box that can be sliced ​​in the patent notification number CN102292030B Chinese patent. However, ...
