Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an ESD specimen fixing device. Background Art

[0002] ESD, also known as endoscopic submucosal dissection, is widely used in the diagnosis and treatment of precancerous lesions and early cancers of the digestive tract. It is an endoscopic minimally invasive treatment method with advantages such as less trauma, low cost, and easy tolerance by patients. Its pathological examination requirements are different from those of conventional biopsy specimens. It is necessary not only to determine the histological type of the lesion, but also to clarify the horizontal and vertical resection margins of the lesion, the depth of infiltration, and whether there is lymph node and vascular metastasis, so as to provide diagnosis and treatment direction for subsequent treatment.

[0003] After ESD surgery, tissue autolysis will occur after the specimen is removed from the body, so the specimen needs to be immersed in formalin solution to prevent deformation and decay of the pathological specimen. Specimen fixation often requires three items: specimen plate, specimen box and fixation pin. First, the pathological specimen is flattened and pinned to the specimen plate with a fixation pin, then the specimen plate is placed in the specimen box and immersed in formalin, and finally the lid is closed. After the specimen is fixed, the specimen needs to be sampled, and then a series of operations and tests are performed for pathological observation and diagnosis.

[0004] In Chinese patent CN201620190399.9, an ESD specimen measurement and specimen fixing device is provided, including a box body, wherein the box body is provided with grids arranged in a matrix, and the grids are arranged in 10*10; the box body is a 5*5*2cm cube; the grids are filled with rubber material; the left side wall and the upper side wall of the box body are provided with rulers; the rulers are set in millimeters; the grids of the box body are set at a position 1cm away from the top of the box body; and a fixed nail storage box is also provided on the right side wall of the box body. Although the ESD specimen measurement and specimen fixing device can realize specimen measurement, fixation, storage and immersion. However, the specimen is directly placed in the box body, which has certain inconveniences during operation. Moreover, in order to enable the box body to immerse the specimen, the overall structure is relatively complex. On the other hand, after the specimen is immersed, it is very inconvenient to take it out later.

[0005] Therefore, it is necessary to provide an ESD specimen fixing device which is easier to operate and more convenient to take and place. Utility Model Content
