Embodiment Construction

[0010] Below in conjunction with accompanying drawing this embodiment will be further described

[0011] Depend on Figure 1-4 It can be seen that firstly, the tissue is placed in the middle of the bottom of the embedding mold 1 with holes in the densely packed embedding mold 1, and the plant tissue protein extract agar is dripped on one or more arranged tissues. It becomes relatively larger, and multiple tissues can be covered together, and it looks like only one organization. The cassettes are then snapped onto the base without losing any tissue within.

[0012] Then dehydration, the permeability of the plant tissue protein extract is no different from that of biological tissue. The dehydration effect is the same. After the tissue is dehydrated, it is still fixed on the bottom mold and directly embedded, which again avoids the key link of tissue dislocation. After the tissue is embedded in wax, each tissue in the wax block tissue formed by cooling still exists independent...

Abstract

The invention provides a small biological tissue fixing method, belonging to the field of small pathological tissue fixing methods. The method is mainly characterized in that pathological tissue is directly put into an embedding mold with holes; as one drop or two drops of plant protein liquid is dripped on one or more pieces of small pathological tissue, and plant protein and the tissue aggregatetogether, and the plant protein can wrap and cover the tissue; and after dehydration is conducted on the pathological tissue in the embedding mold at a time, the embedding mold with holes is buckledwith a bottom cover having small bulges to seal the small holes in the embedding mold, wax liquid is directly injected to embed the pathological tissue, and then cooling is performed. The method has the advantages that a large amount of time is saved; errors generated during tissue guiding are avoided, small tissue is not prone to losing, and error accidents are avoided; and the complexity of workis improved.

Description

Technical field: [0001] The invention relates to a method for the link of the tissue fixing step before the biological tissue is subjected to cell detection. Background technique [0002] At present, small tissue specimens such as intestinal endoscopes and cystoscopes account for a considerable proportion in pathological biopsies, but because of their small size, many hospitals use filter paper to wrap them, and also use densely-closed embedding boxes. For embedding cassettes, tiny tissues may also be lost, and tiny tissues must be dehydrated before embedding. The process of putting small tissues into filter paper for dehydration, and then taking them out for embedding requires careful attention. Sometimes a few pieces of small tissues are placed in a filter paper bag, and they will be lost if you don’t pay attention, or they will be worn out. Even densely packed cassettes can be lost by tissue that is too small! Losing tissue is a serious loss and thus a medical malpracti...
