In the field of medical laboratory equipment technology, we provide a case for fixing tissue samples for endometrial polyp research. [Solution] The sample containment groove 5 on the base 1 contains and maintains the shape of the tissue, and the fixative penetrates from below through the micropores at the bottom. The limiter 2 is detachable from the base. The flexible pressing piece of the pressing member is attached to the limiter via a connecting arm and lightly presses the tissue surface from directly above the sample containment groove. The seal lid 4 is sealed to the base, forming a sealed cavity. This ensures stable sample retention and uniform penetration of the fixative, enabling highly structurally complete fixation. Conventionally, when immersing endometrial polyp tissue samples in fixative, their sparse and small structure makes them prone to floating, folding, or mutual adhesion, hindering uniform penetration of the fixative and causing the initial spatial morphology to collapse. This made it difficult to locate the target region in subsequent embedding and sectioning processes, raising concerns about reduced accuracy in pathological analysis.
