Description

Technical Field

[0001] This utility model belongs to the field of medical specimen fixation plates, and more specifically, relates to a specimen fixation plate used after digestive endoscopy. Background Technology

[0002] Currently, in the diagnosis and treatment of digestive endoscopy, the standard postoperative procedure for large, flat tissue specimens obtained through endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) is to flatten and fix them on a rigid plate, and then soak them in formalin solution for subsequent pathological evaluation.

[0003] Currently, the fixation plates widely used in clinical practice are mostly ordinary cork boards, foam boards, or cardboard, and are fixed with pins or ordinary safety pins. This method originates from traditional practices, and although it is common, it has serious shortcomings and can no longer meet the needs of modern precise pathological diagnosis.

[0004] The shortcomings of existing technology:

[0005] (1) The specimen location is unclear, which seriously affects the accuracy of pathological assessment;

[0006] Precise assessment of surgical margin status is impossible: The "negative surgical margin" status in the pathology report is crucial for determining whether the tumor has been completely removed and for deciding on subsequent treatment plans. Current standard fixation plates lack any graduated references, preventing endoscopists from accurately marking the specimen's orientation (e.g., oral, anal, anterior, posterior) and measuring the surgical margin distance during fixation. This makes it difficult for pathologists to trace the original position of the tissue block within the body and its corresponding surgical margin during endoscopic observation, significantly increasing the difficulty and uncertainty in assessing the lateral surgical margin status. This can affect accurate disease staging and even mislead clinical decisions.

[0007] Lack of objective measurement standards: Intraoperative measurement of specimen size can only rely on estimation or the use of a separate ruler, which is cumbersome and inaccurate, and is not conducive to the immediate assessment of surgical results and the standardized recording of clinical data.

[0008] (2) The fixation effect is not reliable, which leads to specimen deformation and damage to diagnostic materials;

[0009] Specimens are prone to curling and detachment: The bonding strength between the pin and the corkboard is limited. During transportation and prolonged formalin immersion, the pin can easily loosen and detach, causing the specimen to separate from the board and curl. Curled and deformed specimens cannot be restored to their original stretched state after fixation. This non-physiological deformation can significantly affect the pathologist's accurate judgment of lesion size, depth of invasion, and vascular and lymphatic vessel involvement, increasing the risk of diagnostic errors.

[0010] (3) Lack of operational flexibility leads to waste and inconvenience;

[0011] The corkboard cannot fit the specimen: Commercially available corkboards are of fixed size, while endoscopic specimens vary greatly in shape and size. For small specimens, using a large board will result in material waste; for huge or irregular specimens, the size of a single board may be insufficient, and splicing and fixing will be more difficult and irregular.

[0012] Manual cutting is difficult: If the fixation plate needs to be cut, the existing tools (such as scalpels and scissors) are not only inconvenient to operate and inefficient, but also produce rough and uneven edges that may cause cuts to medical staff and are not aesthetically pleasing.

[0035] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0036] Reference Figures 1 to 3 As shown, a specimen fixation plate for postoperative digestive endoscopy is provided, including a base plate 1 and specimen pins. The edges of the base plate 1 are provided with several scale lines 2. The base plate 1 is provided with multiple tearable grid units 3. Each grid unit 3 is connected to the other, and there is a cross intersection point between every four grid units 3. The base plate 1 is made of corrosion-resistant foam board so that the specimen pins can be fixed at any position on the base plate 1.

[0037] In this embodiment, the substrate is placed on a table, and the user lays the specimen flat on the substrate. Following the specimen's outline, the user manually removes excess mesh units, ensuring the substrate perfectly fits the specimen's shape. Specimen staples are then used to press into the through-holes at key points requiring fixation. Finally, the substrate, connected to the specimen, is placed into a specimen bag and sent to the pathology department. This specimen fixation plate can be cut to any shape to fit the specimen. The substrate is made of corrosion-resistant foam board, allowing for accurate fixation with specimen staples at any position. It is also equipped with graduations for quick measurement and easy recording. The specimen staples cooperate with the substrate 1 to prevent the specimen from curling or deforming during formalin fixation. It can be freely cut according to the specimen's size and shape, maximizing space utilization and adapting to different surgical needs. It is best cut into a square structure for ease of use by medical staff.

[0038] In some embodiments of this utility model, a groove 31 is provided between adjacent grid units 3.

[0039] In some embodiments of this utility model, a foldable portion 32 is provided between two adjacent grid units 3. The foldable portion 32 is provided with several round holes. When sufficient bending force is applied to the grid unit 3, the foldable portion 32 can be easily broken. The round holes reduce the required bending force, and it can be easily disassembled without tools.

[0040] In some embodiments of this invention, both the grid unit 3 and the foldable part 32 are made of corrosion-resistant foam board to facilitate the insertion and fixation of the specimen needle.

[0041] Preferably, the foam board is made of medical-grade materials.

[0042] In some embodiments of this invention, the four corners of the substrate 1 are rounded to avoid scratches.

[0043] In some embodiments of this utility model, the specimen nail has a conical tip, a cylindrical shaft, and a flat, round needle head. The specimen nail is similar to a miniature "I" shaped nail or "tack". The conical tip is easy to pierce tissue, the diameter of the cylindrical shaft matches the diameter of the through hole 41 on the substrate, and the flat, round needle head is easy to press with a finger and can prevent the nail from completely penetrating the substrate 1.

[0044] Preferably, the length of the conical tip is less than the thickness of the substrate 1.

[0045] In some embodiments of this utility model, the substrate 1 has dimensions of 100mm × 100mm × 1.5mm.

[0046] In some embodiments of this utility model, the size of the grid unit 3 is 2mm × 2mm.

[0047] In some embodiments of this utility model, the substrate 1 is provided with scale markings. The scale markings are located on one side of the scale line 2. In both the longitudinal and transverse directions, there is a thickened scale line every 5 mm, and it is marked with numbers (such as 0, 5, 10, 15... mm), forming a clear scale ruler, which is convenient for quick reading and recording.

[0048] The above is a further detailed description of this utility model and should not be considered as a limitation on the specific implementation of this utility model. For those skilled in the art, simple deductions or substitutions without departing from the concept of this utility model are all within the protection scope of this utility model.
