[0002] The Department of Pathology is one of the indispensable departments in large comprehensive hospitals. Its main task is to undertake pathological diagnosis in the medical process, including providing clear pathological diagnosis for the clinic, determining the nature of the disease and finding out the cause of death through biopsy, exfoliative and fine needle aspiration cytology and autopsy.

[0003] The work of the pathology department has led to the storage of a large number of pathology samples within the department, including various tissue sections, tissue fluids, cell mixtures, etc. During this process, when pathology sample testing is required, a sample sampler is needed.

[0004] Generally, the sampler used for sampling in pathology departments is similar to a puncture syringe, which is used to absorb sample solution and cell tissue, so that they can be placed in glass slides and containers for subsequent observation under a microscope. However, this type of sample sampler still has certain problems and limitations: most existing pathology sample samplers require manual operation, and the absorption volume cannot be accurately controlled, which affects the accuracy of sampling. At the same time, after the sampling is completed, it cannot be quickly transferred to the other side for testing, and the flexibility is not strong. Utility Model Content
