Description

Technical Field

[0001] This utility model relates to the field of clinical medical pathological sample collection, and in particular to a specimen fixation box. Background Technology

[0002] All surgically removed or biopsy samples must be sent to the pathology department after being removed from the body. After thorough fixation, further sampling and other related work are carried out. Only after multiple processing steps can a pathology report be obtained, ultimately providing the gold standard for the patient's diagnosis and treatment. The quality of the specimen is the foundation for ensuring accurate diagnosis. In order to protect the specimen, a specimen fixation box is required.

[0003] Currently, all samples are uniformly placed in embedded boxes after collection. Although the size and style of the embedded boxes provided by different manufacturers vary slightly, they are all plastic embedded boxes without special fixing devices. However, pathological samples come from various organs of the human body, and their size and shape vary depending on the method of sample acquisition. Some surgically removed samples and endoscopic puncture biopsy samples have special requirements for fixation and subsequent embedding and sectioning. Therefore, it is urgent to process such samples with special requirements in a special way. On the one hand, this ensures that such samples maintain a specific shape during fixation and embedding, and on the other hand, it ensures that the quantity of samples is not lost due to subsequent processing, ultimately safeguarding subsequent clinical diagnosis and treatment. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a specimen fixation box, which aims to improve the problem that the specimen fixation boxes currently on the market are all devices of uniform shape and size, and cannot meet the fixation needs of samples of different shapes and sizes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a specimen fixing box, including a fixing device, wherein a cuttable deformable device is provided at the bottom of the inner wall of the fixing device, and multiple cutting lines are provided in the middle of the outer wall of the cuttable deformable device. A fixing cover is provided at the top of the inner wall of the fixing device, and a separable dotted line is provided in the middle of the outer wall of the fixing cover. Two locking blocks are fixedly connected to the top right side of the separable dotted line, and two slots are provided on the top left side of the separable dotted line. The two locking blocks engage with the corresponding slots.

[0006] As a further description of the above technical solution:

[0007] Limiting rods are fixedly connected to the four corners of the inner wall of the fixture, and multiple limiting holes are opened at the bottom of the fixing cover. The multiple limiting rods are respectively engaged with the corresponding limiting holes.

[0008] As a further description of the above technical solution:

[0009] The outer wall of the fixture has a reserved groove on the front side. An information plate is connected to the inner wall of the reserved groove. The upper and lower sides of the outer wall of the information plate are fixedly connected to the second locking block. The upper and lower sides of the inner wall of the reserved groove are provided with the second locking slot. The two second locking blocks are respectively engaged with the corresponding second locking slot.

[0010] This utility model has the following beneficial effects:

[0011] In this invention, multiple samples can be fixed by using a cuttable deformable device in conjunction with different samples. For endoscopic puncture samples, the cuttable deformable device is cut along the grid lines to clamp the sample, maintaining its original shape and ensuring accurate embedding. For samples such as fetal membrane rolls, the device is cut along the circular lines to avoid sample loss and clarify the embedding direction. The fixing cap works with the fixator through a separable dotted line. When fixing small endoscopic tissues, the cap is folded to enhance stability. When the tissue and the embedding box are aligned, the cap can be torn open to ensure fixation and dehydration. These structural combinations improve the problem that existing specimen fixation boxes are uniform in shape and size and cannot meet the needs of fixing different samples.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a specimen fixation box, including a fixator 1. The fixator 1 is made of medical-grade material, which can minimize the impact of fixative penetration and standardize sample collection requirements. The bottom of the inner wall of the fixator 1 is provided with a cuttable deformable part 2. The outer wall of the cuttable deformable part 2 has multiple cutting lines 3 in the middle. The cutting lines 3 are divided into grid lines and circular lines to fix samples of different shapes. The grid lines can fix and clamp the original shape of endoscopic puncture samples, such as gastric, intestinal polyps, and liver and lung puncture samples, ensuring that the embedding can be carried out according to the inherent shape of the sample. At the same time, the fixator 1 can also be used as a background to better display the location of the tissue when adding chromogenic agents and marking tissues. The circular lines can fix fetal membrane rolls and mucosa for observation of multi-layer cell morphology. The sample can avoid the sample loss caused by traditional fixation with long nails and other fixators 1, and can also identify the embedding direction to ensure the accuracy of subsequent work. The top of the inner wall of the fixator 1 is provided with a fixation cover 4, and the middle of the outer wall of the fixation cover 4 is provided with a separable dotted line 5. The separable dotted line 5 serves as a folding divider line, which can ensure the stability of the fixator 1 when clamping small endoscopic tissues, and prevent them from being deviated by the impact of related liquids during fixation and dehydration. It can also be used alone, and can be torn open when the tissue thickness is equal to that of the embedding box to ensure good fixation and dehydration effect of the tissue in the fixation and dehydration solution. Two locking blocks 6 are fixedly connected to the top right side of the separable dotted line 5, and two slots 7 are provided on the top left side of the separable dotted line 5. The two locking blocks 6 engage with the corresponding slots 7 respectively.

[0022] Specifically, the fixator 1, as the core component, is made of medical-grade materials, which minimizes the impact on the penetration of the fixative solution and standardizes sample collection requirements. Its inner wall has a cuttable deformable element 2 at its bottom, and its outer wall has multiple cutting lines 3 in the middle. When dealing with endoscopic puncture samples, such as gastric, intestinal polyps, and liver and lung puncture samples, the sample can be cut along the grid lines according to its shape. The cuttable deformable element 2 can hold the sample in place, maintaining its original shape, facilitating subsequent embedding operations according to the sample's inherent morphology. Furthermore, when adding chromogenic reagents to label tissue, the fixator 1 can also serve as a support, clearly displaying the tissue location. For fetal membrane rolls and mucosal samples requiring observation of multi-layered cell morphology, the sample can be cut along the circular lines. This method avoids sample loss caused by traditional long nail fixation, while also clearly defining the embedding direction and improving subsequent embedding efficiency. To ensure continued accuracy, the fixing cover 4 located at the top of the inner wall of the fixator 1 and the separable dotted line 5 in the middle of the outer wall are key design features. When fixing small endoscopic tissues, the fixing cover 4 is folded along the separable dotted line 5, which, in conjunction with the fixator 1, enhances the stability of the clamped tissue and prevents tissue deviation due to liquid impact during fixation and dehydration. When the tissue thickness is equal to that of the embedding cassette, a portion of the fixing cover 4 can be torn along the separable dotted line 5 to ensure that the tissue is fully in contact with the fixation and dehydration solutions, achieving good fixation and dehydration effects. In addition, the two locking blocks 6 on the top right of the separable dotted line 5 engage with the two locking slots 7 on the left, further ensuring the stability of the fixing cover 4 during use and enabling it to better fulfill its function to meet the fixation needs of samples of different shapes and sizes.

[0023] Reference Figure 1 , Figure 4 and Figure 5 Limiting rods 8 are fixedly connected to the four corners of the inner wall of the fixing device 1. Multiple limiting holes 9 are opened at the bottom of the fixing cover 4, and the multiple limiting rods 8 are respectively engaged with the corresponding limiting holes 9.

[0024] Specifically, the limiting rods 8 at the four corners of the inner wall of the fixture 1 cooperate with the limiting holes 9 at the bottom of the fixing cover 4. When installing the fixing cover 4, the limiting rods 8 are aligned with the limiting holes 9 and pressed down, and the two are engaged. This design not only accurately positions the fixing cover 4 and ensures that its installation position is accurate, but also enhances the stability of the connection between the fixing cover 4 and the fixture 1, preventing the fixing cover 4 from shifting or falling off during use.

[0025] Reference Figure 1 , Figure 2 and Figure 6 The front side of the outer wall of the fixture 1 is provided with a reserved groove 10. The inner wall of the reserved groove 10 is provided with an information plate 11. The upper and lower sides of the outer wall of the information plate 11 are fixedly connected with a second card block 12. The upper and lower sides of the inner wall of the reserved groove 10 are provided with a second card slot 13. The two second card blocks 12 are respectively engaged with the corresponding second card slot 13.

[0026] Specifically, a reserved groove 10 is provided on the front side of the outer wall of the fixture 1 for placing the information plate 11. The second locking block 12 on the upper and lower sides of the outer wall of the information plate 11 corresponds to the second locking groove 13 on the upper and lower sides of the inner wall of the reserved groove 10. During installation, the second locking block 12 of the information plate 11 is aligned with the second locking groove 13 and inserted into the groove to securely fix the information plate 11, which facilitates the recording and viewing of specimen-related information.

[0027] Working principle: When dealing with different types of samples, the specific operating procedure is as follows: For endoscopic puncture samples, such as gastric and intestinal polyps, as well as liver and lung puncture samples, first carefully observe the sample shape, and then cut along the grid lines in the middle of the outer wall of the cuttable deformable 2 according to the sample morphology. After cutting, use the cuttable deformable 2 to clamp the sample, thus maintaining the original shape of the sample. In this way, the subsequent embedding operation can be carried out according to the inherent shape of the sample, ensuring the accuracy of embedding. Furthermore, when it is necessary to add chromogenic reagent to mark the tissue, place the sample in the fixator 1. At this time, the fixator 1 can act as a support base, so that the tissue position can be clearly displayed. If it is a fetal membrane roll or a mucosal sample that requires observation of the morphology of cells in multiple layers, then cut along the grid lines in the middle of the outer wall of the cuttable deformable 2. The circular lines of the part are cut, which avoids sample loss caused by traditional long nail fixation, and can also clarify the embedding direction, thereby improving the accuracy of subsequent work. Regarding the use of the fixation cover 4, when fixing small endoscopic tissues, the separable dotted line 5 in the middle of the outer wall of the fixation cover 4 is used as the folding dividing line to fold the fixation cover 4. The folded fixation cover 4 cooperates with the fixator 1 to enhance the clamping stability of the tissue, thereby effectively preventing the tissue from deviating from its original position due to the impact of related liquids during fixation and dehydration. When the tissue thickness is equal to that of the embedding box, a part of the fixation cover 4 is torn along the separable dotted line 5. This ensures that the tissue is in full contact with the liquid in the fixation and dehydration solution, thereby achieving good fixation and dehydration effects.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
