[0002] The pathology department is one of the essential departments in large general hospitals. Its main task is to undertake pathological diagnosis during the medical process, including providing a clear pathological diagnosis for the clinic through biopsy, exfoliative and fine needle aspiration cytology, and autopsy, determining the nature of the disease, and finding out the cause of death. Pathological diagnosis is to perform histological examination under a microscope on tumor specimens removed by surgery or autopsy, fixed and stained. Before treatment, tumor tissues are obtained by forceps, resection or biopsy, fixed and stained, and then pathological diagnosis is carried out under a microscope.
[0003] The existing staining devices cannot completely fix the items during staining, and are prone to falling off. Generally, they can only stain one glass slide at a time, with low work efficiency and cumbersome use, which increases a certain workload for medical staff.
[0004] Therefore, a device for special staining in pathological diagnosis is needed, which can conveniently and quickly stain multiple glass slides, keep the glass slides stable, and improve the work efficiency of medical staff. Content of the Utility Model
