Description

  The present invention relates to a pathological specimen management method, and more particularly to a pathological specimen management method for storing and managing an excised cancerous part and monitoring a metastasis state or the like later or as a specimen.

  Conventionally, as a method for managing the pathological specimen, a method has been used in which the affected part (specimen) excised and removed is fixed to the surface of a wooden board, a cork board, a rubber board, or in some cases a corrugated board using a plurality of insect pins. ing. This specimen is photographed and recorded as necessary.

  Thus, the specimen fixed to the board body with the insect pin is usually fixed in tissue with 10% formalin solution or the like. This formalin fixation may be accompanied by freezing. This is to prevent the tissue from rotting and to give a certain hardness to facilitate subsequent cutting.

  In addition, macroscopic observation is important for pathological diagnosis, which is cut into a size that can be observed with a microscope. In order to observe with a microscope, it is necessary to reduce the thickness so that light can be transmitted. Therefore, tissue processing with paraffin is performed. The tissue is infiltrated with paraffin using alcohol or an organic solvent, and the tissue pieces that have been infiltrated with paraffin in detail are hardened into paraffin (paraffin embedding).

  Next, using a microtome, a section of 3 μm is usually prepared (thin section), and then stained with hematoxylin and eosin. The cell nucleus is stained with hematoxylin in purple, and the cytoplasm and connective tissue are stained in red pink with eosin.

  However, this conventional work, in particular the work of fixing and fixing the specimen to the board body with a plurality of insect pins and the work of removing the insect pins, imposes a very heavy burden on the operator and is inefficient. Furthermore, there is a risk of needlestick accidents due to insect pins and secondary infection associated therewith.
