Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically a standardized rapid pathological tissue sampling device. Background Technology

[0002] Histopathology focuses on studying changes and abnormalities in disease structure and cells to provide a basis for diagnosis, treatment, and prognostic assessment. This process involves microscopic observation and analysis of diseased tissue specimens to investigate the morphological characteristics and pathophysiological basis of related pathological changes. Tissue sampling is a crucial step in obtaining human tissue specimens, typically performed through surgical resection, biopsy, or autopsy. The obtained tissue specimens must undergo fixation, embedding, and sectioning before subsequent microscopic examination.

[0003] Currently, manual sampling is the primary method, but it presents several challenges. Manual sampling is susceptible to individual skill levels and subjective factors, leading to poor consistency in results among different operators. Furthermore, manual sampling involves direct contact with the specimen, posing risks of cross-contamination and human error—all issues requiring attention. Existing manual sampling devices require multiple operations to obtain the final tissue sample.

[0004] For example, Chinese utility model patent CN210953437U discloses "a precise tissue sampling device for pathology," which uses the rotation of a blade to cut tissue and a graduated limiter to assist in precise cutting. This method requires multiple, multi-directional cuts to obtain tissue specimens of a specified size, making it impossible to obtain them in one go, thus resulting in low sampling efficiency.

[0005] Chinese utility model patent CN210347277U discloses a "pathological laboratory specimen sampling and cutting device" that uses an electric motor to drive a circular blade to cut tissue samples placed in a cutting groove on a base plate. This method can obtain a circular tissue sample in one pass, but it requires transferring the sliced ​​tissue to a designated area below the circular blade. Since tissue samples tend to stick together, changing the cutting position is inconvenient and can damage the thin tissue slices. Furthermore, the blade is located inside the device, making cleaning difficult.

[0006] Chinese utility model patent with announcement number CN209689956U discloses "a refined pathological sampling device", which uses a set of thread knives to quantitatively control the cutting thickness of tissue samples. However, the thread knives are not as sharp as conventional cutting blades when cutting tissue samples, which can cause tearing and deformation of the tissue samples.

[0007] Therefore, a standardized and rapid pathological sampling device is proposed to address the above problems. Utility Model Content
