Technical Field
[0001] This utility model relates to the field of medical supplies technology, specifically to a prostate biopsy tissue specimen box. Background Technology
[0002] Patients diagnosed with suspected prostate cancer due to elevated prostate-specific antigen (PSA) levels, ultrasound, or MRI findings suggesting suspicious prostate nodules require further pathological examination via prostate biopsy to confirm the diagnosis.
[0003] On the one hand, currently, after a prostate biopsy, the tissue is generally preserved in formalin vials. This method can only preserve one tissue sample per vial, making the procedure cumbersome, requiring a large amount of materials, and it cannot achieve staining and labeling of tumor tissue. On the other hand, current conventional biopsy methods can only obtain the length of each biopsy tissue and the benign / malignant pathological diagnosis, but cannot accurately mark the head and tail of the biopsy tissue. Consequently, it is impossible to reproduce the pathological diagnosis of the biopsy tissue in the patient's prostate MRI, and thus cannot reproduce the spatial location of the tumor tissue in the prostate gland.
