Problems solved by technology
[0002] Pathological specimens should be fully fixed before taking materials, which is beneficial to the collection and complete preservation of the tissue and cell structure of the specimens. All parts of the specimens are soaked in the fixative solution. When there are luminal organs fixed, if they are not cut and fixed, the luminal surface tissues are not easy to fully contact and fix. The ideal fixation effect can be achieved, which will easily cause autolysis and necrosis of the tissue cells of the specimen, and the physical structure will be destroyed. At present, the fixation of pathological specimens with cavities cannot effectively expose the lesions. Some of them are fixed with wooden boards and pins. This method is more complicated to operate. The wall of the cut large specimen is easy to stick to the wall, resulting in insufficient fixation on one side.

Embodiment Construction
[0011] As shown in the figure, the cavity organ pathological specimen holder is composed of a bottom plate 1, a fixing clip 3, and a slideway 2. The bottom plate 1 is provided with a slideway 2, and each slideway 2 is provided with a fixing clip. 3. The invention has the advantages of novel structure, convenient operation and low cost, and can facilitate the tiling and fixing of pathological specimens of cavities of organs of different sizes, and a gap equivalent to the height of the slideway is left between the tissues and the bottom plates, so that the lesions can be fully exposed to the fixative, and the best results can be obtained. Good fixation effect, conducive to pathological observation and material collection.

The invention relates to a fixator for the pathological specimens of viscera with cavities. The fixator consists of a bottom plate, fixing clips and slide rails, wherein the bottom plate is provided with the slide rails; and each slide rail is provided with one fixing clip. The fixator has a novel structure and low cost and is convenient to operate; the pathological specimens of the viscera with the cavities of different sizes are convenient to spread and fix; and air gaps with the size equivalent to the height of the slide rails are reserved among tissues on the bottom plate, so that pathological changes are fully exposed to fixing solution, an optimal fixing effect is achieved, and pathological observation and material taking are facilitated.
Description
technical field [0001] The invention relates to a fixer for pathological specimens of cavities, which can conveniently cut and fix pathological specimens of cavities, expose lesion parts to the greatest extent, and facilitate pathological observation and material collection. Background technique [0002] Pathological specimens should be fully fixed before taking materials, which is beneficial to the collection and complete preservation of the tissue and cell structure of the specimens. All parts of the specimens are soaked in the fixative solution. When there are luminal organs fixed, if they are not cut and fixed, the luminal surface tissues are not easy to fully contact and fix. The ideal fixation effect can be achieved, which will easily cause autolysis and necrosis of the tissue cells of the specimen, and the physical structure will be destroyed. At present, the fixation of pathological specimens with cavities cannot effectively expose the lesions. Some of them are fixed...
