Description

Technical Field

[0001] This utility model relates to the field of medical specimen processing technology, and in particular to a specimen box for fixing digestive tract ESD and EMR mucosal specimens. Background Technology

[0002] Endoscopic submucosal dissection (ESD) and endoscopic mucosal resection (EMR) are two common endoscopic treatment techniques for the digestive tract, primarily used to treat early-stage cancers and benign tumors. ESD is suitable for broad-based polyps and sessile polyps in the gastrointestinal tract larger than 2 cm in diameter; early-stage gastrointestinal cancers without lymphatic or hematogenous invasion or metastasis, regardless of lesion location or size, can be removed using ESD; and submucosal tumors of the digestive tract larger than 2 cm in diameter. EMR is suitable for obtaining tissue specimens, digestive tract polyps, early-stage digestive tract cancers smaller than 2 cm and confined to the mucosal layer, and some tumors originating from the muscularis mucosae and submucosa. After performing ESD or EMR, the resected specimen needs to be preserved for pathological diagnosis and analysis. Current techniques often involve placing the mucosal specimen on a foam board, fixing it with pins, then placing the foam board in a polyethylene specimen bag or box, and immersing it in 10% neutral formalin solution for standardized processing and transport.

[0003] In the prior art, please refer to the ESD specimen fixation and measurement box disclosed in CN2198221327U. In the prior art, after placing the foam board with the fixed mucosal specimen into the specimen bag or specimen box, the foam board is prone to flipping during transportation due to factors such as vibration and solution buoyancy, which causes the specimen to not be completely immersed in the solution, affecting the accuracy of subsequent pathological testing.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0005] To address the problem that in existing technologies, foam boards used to fix mucosal specimens are prone to tipping over during storage and transport when placed in specimen bags or boxes, due to vibrations and solution buoyancy, resulting in incomplete immersion of the specimen in the solution and affecting the accuracy of subsequent pathological testing, this invention provides a specimen box for fixing mucosal specimens for ESD and EMR of the digestive tract.

[0006] This utility model is achieved through the following technical solution: A specimen box for fixing digestive tract ESD and EMR mucosal specimens, wherein the specimen box for fixing digestive tract ESD and EMR mucosal specimens comprises: The box body has a surrounding plate arranged around the opening on the upper side of the box body.

[0012] The specimen box for fixing digestive tract ESD and EMR mucosal specimens includes a plurality of sealing rings fitted on the outer side of the surrounding plate. The sealing rings are spaced at a certain distance. When the cover is fitted onto the surrounding plate, the inner wall of the cover is in interference fit with the sealing rings.

[0013] The specimen box for fixing digestive tract ESD and EMR mucosal specimens has a pressure groove on each of the two sides of the cover, the pressure groove is recessed, and the outline of the pressure groove is oval.

[0014] The specimen box for fixing digestive tract ESD and EMR mucosal specimens, wherein the partition is provided with grid lines, and adjacent lines in the grid lines are spaced apart at a predetermined size; The partition includes a plurality of detachably mounted pins, which are polypropylene pins, and the ends of the pins are blunted along a predetermined arc.

[0015] The specimen box for fixing digestive tract ESD and EMR mucosal specimens includes an anti-slip pad fixedly provided on the lower side of the box body. The anti-slip pad has several anti-slip grooves along the length and width of the box body, and the intersections of the anti-slip grooves in different directions are arranged to intersect.

[0016] The beneficial effects of this utility model are as follows: By setting guide rail grooves on opposite sides inside the receiving cavity of the box, this utility model forms a limiting effect on both sides of the partition, which can prevent the partition from flipping during the transportation of the specimen box. When the lid and the box are combined, the tenon on the lid is inserted into the corresponding guide rail groove, which increases the bonding strength between the lid and the box and limits the partition, thereby ensuring the immersion state of the specimen in the solution, improving the tissue antigen preservation rate and ensuring the accuracy of pathological detection.

Detailed Implementation

[0019] To make the objectives, technical solutions, and effects of this utility model clearer and more explicit, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0020] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0021] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0022] In the prior art, please refer to the ESD specimen fixation and measurement box disclosed in CN2198221327U. In the prior art, after placing the foam board with the fixed mucosal specimen into the specimen bag or specimen box, the foam board is prone to flipping during transportation due to factors such as vibration and solution buoyancy, which causes the specimen to not be completely immersed in the solution, affecting the accuracy of subsequent pathological testing.

[0023] To address the aforementioned problems in the existing technology, this utility model provides a specimen box for fixing digestive tract ESD and EMR mucosal specimens, such as... Figure 1 and Figure 2 As shown, the specimen box for fixing digestive tract ESD and EMR mucosal specimens includes: a box body 100, with a surrounding plate 110 arranged around the upper opening of the box body 100, and guide rail grooves 120 respectively arranged on opposite sides of the surrounding plate 110, the guide rail grooves 120 extending along the height direction of the box body 100 into the receiving cavity of the box body 100; a partition 200, with the two sides of the partition 200 detachably arranged in the receiving cavity corresponding to the two guide rail grooves 120; and a cover, which is detachably fitted onto the surrounding plate 110, with two tenons 310 arranged inside the cover corresponding to the positions of the two guide rail grooves 120, and when the cover and the surrounding plate 110 are combined, the two tenons 310 are respectively inserted into the two guide rail grooves 120 and abut against the partition 200.

[0024] This invention provides guide grooves 120 on opposite sides within the receiving cavity of the box 100, which effectively limit the movement of the partition 200 on both sides, preventing the partition 200 from flipping during specimen transport. The tenons 310 on the lid are inserted into the corresponding guide grooves 120 when the lid and box 100 are combined, increasing the bonding strength between the lid and box 100 and limiting the movement of the partition 200. This ensures the specimen remains submerged in the solution, improves the preservation rate of tissue antigens, and guarantees the accuracy of pathological testing.

[0025] In the above embodiments, such as Figure 1 and Figure 2 As shown, the main body of the specimen box for fixing digestive tract ESD and EMR mucosal specimens of this utility model consists of a box body 100, a partition 200, and a cover plate 300. The box body 100 has an opening on its upper side, while the other parts are sealed. The interior of the box body 100 is hollow, forming a receiving cavity. In actual use, the partition 200 can be assembled into the receiving cavity along the opening, and a formalin solution with a pH of 7.4 is poured into the receiving cavity for processing and preserving the digestive tract mucosal specimens fixed on the partition 200. On both sides of the enclosure 110 of the body 100, guide rail grooves 120 are respectively provided in the opposite direction of the receiving cavity. The guide rail grooves 120 can be formed by two spaced protruding tenon structures. The opposite surfaces of the protruding tenon structures should be set at a certain angle as a dovetail-shaped bevel to facilitate the entry of the partition 200. The guide rail grooves 120 extend along the height direction of the box body 100 into the receiving cavity of the box body 100 to constrain the partition 200 and prevent the partition 200 from flipping over due to bumps during the transport of the specimen box.

[0026] The partition 200 can be made of medical-grade blue silicone. The thickness of the partition 200 should be adapted to the width of the guide rail groove 120, so that when the partition 200 is installed in the box 100, the two sides of the partition 200 can be installed corresponding to the two guide rail grooves 120 respectively. The silicone partition 200 is used to fix the digestive tract mucosal specimen, specifically by fixing it to the detachable pin 220 of the partition 200. This part is described in detail below.

[0027] The lid's dimensions are adapted to the box 100, and the lid's interior is hollow, allowing it to be detachably fitted onto the surrounding plate 110 when combined with the box 100, thus sealing the opening of the box 100. In this embodiment, two tenons 310 are also provided on the inner side of the lid at positions corresponding to the two guide rail grooves 120. When the lid and the surrounding plate 110 are combined, the two tenons 310 are respectively inserted into the two guide rail grooves 120 and abut against the partition 200. The cooperation between the tenons 310 and the guide rail grooves 120 not only increases the bonding strength between the lid and the box 100, preventing the lid from falling off during transportation, but also further limits the partition 200, ensuring that the partition 200 remains stable inside the specimen box and preventing the partition 200 from flipping due to vibration or solution buoyancy, thereby ensuring that the specimen is always immersed in the solution.

[0028] In one possible embodiment of this utility model, such as Figure 1 and Figure 3 As shown, the box body 100 is preferably made of a transparent material, such as a highly transparent copolyester material with a light transmittance of ≥90%, which facilitates medical personnel to observe the condition of the specimen and the liquid level of the solution at any time. An observation surface 130 is provided on one side of the box body 100, and a convex lens 131 integrally formed with the box body 100 is provided on the observation surface 130. Specifically, the convex lens 131 is pre-formed by limiting the shape and size of the observation surface 130 during the manufacturing of the box body 100. In actual use, the side of the partition 200 where the specimen is fixed is installed corresponding to the observation surface 130. The magnifying effect of the convex lens 131 allows medical personnel to observe specimen details more clearly, facilitating the observation of the sample condition during transportation.

[0029] Specifically, in actual settings, such as Figure 1 As shown, the two guide rail grooves 120 are set on the opposite surfaces of the two surrounding plates 110 adjacent to the observation surface 130, so as to form a structure in which the partition plate 200 is parallel to the observation surface 130 after being installed in the receiving cavity, so as to facilitate the correspondence between the convex lens 131 and the specimen. At the same time, when the two guide rail grooves 120 are actually set, the guide rail grooves 120 and the observation surface 130 should be set at a predetermined distance, which should be less than one focal length of the convex lens 131. This setting can ensure that the specimen image observed through the convex lens 131 is upright and magnified, which makes it easier for medical staff to accurately view the details of the specimen and promptly detect possible problems with the specimen, such as whether the specimen has fallen off or whether the solution is clear, thereby further improving the accuracy of specimen status monitoring.

[0030] In the above embodiment, the two guide rail grooves 120 should not be set to the bottom of the receiving cavity of the box 100, so as to avoid forming a sealed partition of the receiving cavity after the partition 200 is installed. Since the two guide rail grooves 120 are not set to the bottom of the receiving cavity, there is space at the bottom after the partition 200 is installed, which can connect the two sides of the partition 200. Therefore, through the principle of communicating vessels, when medical staff pour formalin solution into the receiving cavity, the solution height on both sides of the partition 200 can be the same, thereby ensuring that medical staff can pour the accurate amount of formalin solution, and that the solution height in the box 100 will not change after being subjected to bumps, so as to ensure that the specimen can be completely immersed in the solution.

[0031] In another possible embodiment of this utility model, such as Figure 1 and Figure 3 As shown, a marking section 140 is provided on the box 100 along its height. This marking section 140 can be in the form of scale lines or color-coded markings, and its function is to indicate the liquid level in the containing cavity. Furthermore, a clear mark should be made at the position of 1800ml ± 50ml. This allows medical personnel to quickly and accurately determine whether the solution has reached the appropriate level when infusing formalin solution into the box 100, avoiding situations where there is too much or too little solution. Too much solution may cause overflow, resulting in waste and potential environmental pollution; too little solution may not completely submerge the specimen, affecting the accuracy of pathological testing. The marking section 140 further improves the standardization and accuracy of specimen processing and preservation.

[0032] In another possible embodiment of this utility model, such as Figure 4 and Figure 5 As shown, in order to facilitate medical staff to record specimen information, a first frosted label area 150 is provided on the other side of the box 100 opposite to the observation surface 130. The first frosted label area 150 has an information code positioning frame printed in it, so that medical staff can attach the information code related to the specimen information. When the sample is handed over, medical staff can quickly enter and query the specimen information by scanning the information code.

[0033] On the other hand, a second frosted label area 320 is also provided on the cover. The surface of the second frosted label area 320 is rough, which makes it easy to paste handwritten labels. Medical staff can record basic information of the specimen, collection time, patient information, etc. on the label, which is convenient for subsequent management and query. It also makes it easy for medical staff to scan the information code on the first frosted label area 150 and match it with the handwritten information, so as to form a double verification effect of pathology number and specimen information, effectively preventing the occurrence of discrepancies between sample information and patient information.

[0034] In another possible embodiment of this utility model, such as Figure 1 and Figure 2 As shown, in actual installation, the cross-sectional shape of the tenon 310 is preferably adapted to the structure of the groove in the guide rail groove 120. This arrangement increases the contact area between the tenon 310 and the guide rail groove 120, thereby increasing friction and ensuring stable installation of the cover. Furthermore, since the two guide rail grooves 120 are arranged opposite each other, and the two tenons 310 correspond to the two guide rail grooves 120, the distance between the two tenons 310 and the two guide rail grooves 120 can form a constraint, further improving the installation stability of the cover. In other possible embodiments of this invention, the two tenons 310 can also be configured as an integral plate-like component, which can also achieve the effects of assisting in the installation of the cover and limiting the position of the partition 200.

[0035] In another possible embodiment of this utility model, such as Figure 1 As shown, to prevent the formalin solution in the containing cavity from splashing out due to transport bumps caused by gaps in the combined structure of the box body 100 and the lid, in this embodiment, a plurality of sealing rings 111 are also fitted into the outer side of the surrounding plate 110. The sealing rings 111 are arranged at a certain distance. When the lid is fitted onto the surrounding plate 110, the inner wall of the lid will form an interference fit with these sealing rings 111. This interference fit can effectively seal the gap between the lid and the box body 100, preventing the formalin solution from splashing out due to vibration or bumps during transportation and preventing the formalin solution from evaporating. This ensures the safety of the transportation process and avoids waste of the solution and potential environmental pollution. At the same time, the sealing rings 111 are made of elastic materials, such as rubber or silicone, which can provide a certain cushioning effect while ensuring the sealing performance, reducing the damage that may be caused to the box body 100 or the lid due to hard contact. In addition, the spacing of the sealing rings 111 can also disperse the pressure to a certain extent, avoiding seal failure due to excessive local pressure, thereby further improving the sealing performance and reliability of the specimen box.

[0036] In another possible embodiment of this utility model, such as Figure 3 and Figure 4 As shown, to facilitate medical staff in removing and installing the lid from the box 100, corresponding pressure grooves 330 are provided on opposite sides of the lid. The pressure grooves 330 are oval in shape and recessed from the outer side of the lid inwards. The pressure grooves 330 have a certain depth, allowing medical staff to easily pinch them with two fingers for removal and installation without compromising the overall strength of the lid due to excessive depth. In actual use, medical staff only need to pinch the pressure grooves 330 on both sides with their index finger and thumb to easily apply force to remove or install the lid from the box 100, making the operation more comfortable and effortless.

[0037] In another possible embodiment of this utility model, such as Figure 1As shown, the partition 200 is provided with grid lines 210. The grid lines 210 include lines evenly arranged on the X-axis and Y-axis of the partition 200 surface, and adjacent lines are spaced apart along a predetermined size, such as 0.1 cm. The grid lines 210 facilitate medical staff to more accurately locate and fix the digestive tract mucosal specimen. The size and shape of the digestive tract mucosal specimen can be inferred from the number of grid lines 210 occupied by the digestive tract mucosal specimen, which facilitates the pretreatment of the specimen by medical staff when fixing the specimen.

[0038] The aforementioned partition 200 includes several detachable pins 220. The pins 220 are made of polypropylene, and their ends are blunted along a predetermined arc. Firstly, as a non-metallic material, the pins 220 will not affect the sample's condition due to corrosion. Secondly, the pins 220, in conjunction with the silicone partition 200, allow for puncture of both the specimen and the partition 200 to secure the specimen. When fixing the specimen to the partition 200, medical personnel can accurately insert the pins 220 into the partition 200 using the grid lines 210 as a reference, ensuring the specimen is flat and securely fixed in the predetermined position. This prevents positional shift during transportation due to specimen misalignment or loosening, ensuring the specimen remains in a good submerged state at all times.

[0039] Based on the above embodiments, when the partition 200 is actually installed, it is also preferable to preset the orientation marking information of the partition 200, for example... Figure 1 When setting the grid lines 210 of the partition 200 shown, one side of the lines can be set as dashed lines, thereby giving the partition 200 directional identification. The reason for this is that the standard procedure for endoscopic resection of specimens in the prior art contains the following description: "Endoscopic mucosal resection specimen, unfold the specimen with the mucosal surface facing up, fix it to the rotating board or foam board with pins, mark the oral and anal margins, flip it so that the mucosal surface faces down and place it in the fixation solution." By pre-setting the directional marking information of the partition 200, the oral and anal margins of the sample can be made to correspond to the direction of the partition during the specimen processing stage, which facilitates directional identification during subsequent sample testing. In this way, when performing pathological examination, medical staff can quickly and accurately determine the position of the oral and anal margins of the specimen based on the directional marking information on the partition 200, providing a more accurate and reliable basis for subsequent pathological analysis and diagnosis. Meanwhile, this method of setting directional preset marking information is simple and easy to implement, without increasing manufacturing costs or operational difficulty, yet it plays an important role in specimen processing and testing, greatly improving the standardization and accuracy of the entire pathological testing process, and helping to improve the quality and efficiency of medical diagnosis.

[0040] In another possible embodiment of this utility model, such as Figure 5As shown, in order to ensure that the box 100 can be stably placed on the sample stage during specimen testing, an anti-slip pad 400 is fixedly installed on the underside of the box 100. The anti-slip grooves 410 are made of materials with a high coefficient of friction, such as rubber. Several anti-slip grooves 410 are provided on the anti-slip pad 400 along the length and width directions of the box 100, respectively. The anti-slip grooves 410 in different directions intersect at their intersections, so that the liquid on the sample stage can flow through the anti-slip grooves 410, preventing the box 100 from slipping due to the liquid flowing to the bottom of the stage and the bottom of the box 100. It can also prevent the specimen box from sliding during placement or transportation, ensuring the safety of the specimen.

[0041] The materials used in the above structure should comply with the ISO 13485 medical device manufacturing standard, be sterilized with ethylene oxide, have a sterility period of 3 years, and have a box transparency of ≥90% in accordance with ASTM D1003 standard.

[0042] Based on the above embodiments, the actual usage process of the specimen box for fixing digestive tract ESD and EMR mucosal specimens of this utility model is as follows: First, after obtaining the digestive tract mucosal specimen, the medical staff placed the specimen on the partition 200 and, with reference to the grid lines 210, used pins 220 to fix the collected digestive tract mucosal specimen flat and securely on the partition 200.

[0043] Then, medical staff first install the partition 200 into the receiving cavity along the guide groove 120 at the opening of the box 100, and then pour a formalin solution with a pH of 7.4 into the receiving cavity of the box 100. The specimen status and solution level can be clearly observed through the convex lens 131 on the observation surface 130 on one side of the box 100. During the pouring process, the marking section 140 set along the height direction on the box 100 can be used to quickly and accurately determine whether the solution has reached the appropriate height.

[0044] After filling, the cover is fitted onto the surrounding plate 110. Two tenons 310 on the inner side of the cover, corresponding to the guide rail grooves 120, are inserted into the two guide rail grooves 120 and abut against the partition plate 200, increasing the bonding strength between the cover and the box 100, and further limiting the position of the partition plate 200. When the cover is fitted, several sealing rings 111 fitted onto the outer side of the surrounding plate 110 form an interference fit with the inner wall of the cover, effectively sealing the gap between the cover and the box 100, preventing the formalin solution from splashing out due to vibration or bumps during transportation.

[0045] When it is necessary to record specimen information, medical staff can attach information codes related to the specimen information in the first frosted label area 150 on the opposite side of the observation surface 130 on the box 100, and at the same time, a handwritten label can be pasted in the second frosted label area 320 on the cover to record the basic information of the specimen, collection time, patient information, etc., for convenient subsequent management and retrieval.

[0046] When the specimen box needs to be transported or placed on a sample stage for testing, the anti-slip pad 400 fixedly installed on the underside of the box body 100 can prevent the specimen box from sliding during transportation or placement, ensuring the safety of the specimen.

[0047] In summary, this utility model provides a specimen box for fixing digestive tract ESD and EMR mucosal specimens. The specimen box includes: a box body, with a surrounding plate arranged around the upper opening of the box body, and guide rail grooves arranged on opposite sides of the surrounding plate, extending along the height direction of the box body into the receiving cavity of the box body; a partition, with its two sides detachably disposed in the receiving cavity corresponding to the two guide rail grooves; and a cover, which is detachably fitted onto the surrounding plate, with two tenons arranged inside the cover corresponding to the positions of the two guide rail grooves. When the cover and the surrounding plate are combined, the two tenons are respectively inserted into the two guide rail grooves and abut against the partition. This invention provides guide rail grooves on opposite sides within the receiving cavity of the box, effectively limiting the movement of the partition on both sides. This prevents the partition from flipping during specimen transport. The tenons on the lid are inserted into the corresponding guide rail grooves when the lid and box are assembled, increasing the bonding strength between the lid and box and limiting the movement of the partition. This ensures the specimen remains submerged in the solution, improves the preservation rate of tissue antigens, and guarantees the accuracy of pathological testing.

[0048] It should be understood that the application of this utility model is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
