Description
Technical Field
The invention relates to a paraffin embedding and demolding device for pathological tissues.
Background
In the routine work of the pathology department, the process of supporting the tissue with an embedding medium is called embedding, and the routine section uses paraffin embedding. The specific operation process is that the paraffin which is heated and melted into liquid is injected into the embedding mould, then the pathological tissue is placed in the embedding mould, the embedding forceps are used for pressing the pathological tissue to the bottom of the embedding mould, then the embedding box is covered, and at the moment, the pathological tissue is wrapped by the liquid paraffin and isolated from the air. When the liquid paraffin is cooled and solidified into a solid state, the pathological tissue is embedded in the paraffin to form a pathological tissue wax block. After embedding, the pathological tissue wax block and the embedding box need to be stripped from the embedding mould simultaneously. In the demolding process, no professional tool is available at present, so that the pathological tissue wax block can be broken off by hand or a hard sharp device is used for prying a gap between the pathological tissue wax block and the mold, and then demolding is carried out.
