Abstract
Description
Technical Field
[0001] This application relates to the field of sample encapsulation, and in particular to a simple sample encapsulation device for sessile serrated lesions. Background Technology
[0002] The pathological diagnosis of sessile serrated lesions (SSL) mainly depends on whether the pathological section shows complete crypt structures, including serrated deep crypts, crypt dilatation, and abnormal shape of the crypt base. Therefore, vertical sampling is required for pathological sections to achieve the best results.
[0003] In related technologies, directly immersing samples in formalin can easily cause flattened samples to curl, affecting the observation of crypt basal structures in the slides and leading to misdiagnosis. Alternatively, fixing samples in paper envelopes before immersion in formalin can be cumbersome, result in poor sealing, and lack directional marking. Therefore, this application provides a simple sample encapsulation device. Utility Model Content
[0004] To facilitate the flattening and fixation of the excised specimen and improve the diagnostic accuracy of SSL, this application provides a simple sample encapsulation device for sessile serrated lesions.
[0005] The simplified sample encapsulation device for sessile serrated lesions provided in this application adopts the following technical solution: A simple sample encapsulation device for sessile serrated lesions includes a placement box and a pressure cap. One end of the pressure cap is rotatably connected to the placement box, and the other end is detachably connected to the placement box. The pressure cap is provided with a plurality of permeation holes evenly distributed. When the specimen is placed in the placement box and the pressure cap is installed in the placement box, the pressure cap presses the specimen tightly.
[0006] By adopting the above technical solution, in practical applications, the excised specimen is flattened and placed in the placement box, then the cap is rotated and installed in the placement box so that the cap presses the specimen tightly, quickly achieving the flattening and fixation of the specimen. Afterwards, the whole specimen is immersed in formalin, which contacts the specimen through multiple permeation pores. This operation is simple and convenient, and can solve the problems of curling and orientation confusion in sample fixation, ensuring that pathological sections can be sampled vertically, thereby improving the diagnostic accuracy of SSL.
[0007] Preferably, one end of the placement box has a card slot, and one end of the pressure cover has a card that is engaged in the card slot.
[0008] By adopting the above technical solution, and by setting a card slot and a card, the card is snapped into the card slot to achieve a detachable connection between the cap and the placement box. The structure is simple and the operation is convenient.
[0009] Preferably, there is a gap between the bottom wall of the card slot and the card.
[0010] By adopting the above technical solution, a gap is set between the bottom wall of the card slot and the card to facilitate applying force to the card, thereby making it easier for the card to detach from the card slot.
[0011] Preferably, the sample simple packaging device further includes pearl cotton sheets, the placement box has a placement groove, the pearl cotton sheets are placed in the placement groove, and the pearl cotton sheets are higher than the placement box.
[0012] By adopting the above technical solution, a pearl cotton sheet is set up, and the sample is placed on the pearl cotton sheet. Since the pearl cotton sheet is higher than the placement box, the sample is compressed. In addition, the cut surface of the sample has a high water content, and a slight adsorption force is generated after the sample comes into contact with the pearl cotton sheet, so as to flatten and fix the sample.
[0013] Preferably, the upper side of the pearl cotton sheet is uniformly provided with a wavy pattern.
[0014] By adopting the above technical solution and setting wavy lines, the contact area of the sample is increased, thereby improving the stability of the sample flattening and fixing.
[0015] Preferably, the pearl cotton sheet has scale lines on its upper side.
[0016] By adopting the above technical solution and setting scale lines, it is easier to estimate the size of the sample.
[0017] Preferably, the scale lines are arranged in a cross shape.
[0018] By adopting the above technical solution, and by setting the scale lines in a cross shape, the area where the sample can be measured is increased, and the placement of the sample can be positioned.
[0019] Preferably, the scale line is located at the center of the pearl cotton sheet.
[0020] By adopting the above technical solution, and setting the scale line in the center of the pearl cotton sheet, the sample is placed in the center of the pearl cotton sheet, which facilitates the placement of the sample and allows it to fully contact the formalin.
[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. After removal, the specimen is flattened and placed in the placement box. Then, the cap is rotated and installed in the placement box to press the cap tightly against the specimen, quickly achieving flattening and fixation of the specimen. Afterward, the whole specimen is immersed in formalin. Formalin contacts the specimen through multiple permeation pores. This operation is simple and convenient, and can solve the problems of curling and orientation confusion in sample fixation, ensuring that pathological sections can be sampled vertically, thereby improving the diagnostic accuracy of SSL. 2. By setting up pearl cotton sheets, the sample is placed on the pearl cotton sheets. Since the pearl cotton sheets are higher than the placement box, the sample is compressed. In addition, the cut surface of the sample has a high water content. When the sample comes into contact with the pearl cotton sheets, a slight adsorption force is generated, which facilitates the flattening and fixation of the sample. 3. By setting scale lines, the size of the sample can be estimated. The cross-shaped scale lines increase the area where the sample can be measured and can be positioned. Attached Figure Description

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.
[0025] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0026] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.
[0027] This application discloses a simple sample encapsulation device for sessile serrated lesions.
[0028] Reference Figure 1 and Figure 2The simplified sample encapsulation device includes a placement box 1 and a pressure cap 2. Both the placement box 1 and the pressure cap 2 are rectangular in shape. One end of the pressure cap 2 is rotatably connected to the placement box 1, and the other end of the pressure cap 2 is detachably connected to the placement box 1. The pressure cap 2 has a plurality of permeation holes 21 evenly spaced along the length and width directions of the pressure cap 2. When the sample is placed in the placement box 1 and the pressure cap 2 is installed in the placement box 1, the pressure cap 2 presses the sample firmly.
[0029] In practical applications, the mucosal surface of the removed specimen (i.e., polyp) is flattened and placed in placement box 1. Then, the cap 2 is rotated, and the end of the cap 2 away from the rotating end is installed in placement box 1, so that the cap 2 presses the specimen firmly, quickly achieving flattening and fixation of the specimen. Afterward, the entire specimen is immersed in formalin, which comes into contact with the specimen through multiple permeation holes 21. It can then be transported to the pathology department, or the cap can be opened directly for relevant pathological procedures. This operation is simple and convenient, and it can solve the problems of curling and orientation disorder in sample fixation, ensuring that pathological slides can be sampled vertically, thereby improving the diagnostic accuracy of SSL.
[0030] In some embodiments, a slot 11 is provided at the end of the placement box 1 that is away from the pressure cap 2 and rotates. The slot 11 extends to the upper side of the placement box 1. Correspondingly, a card 22 is formed by protruding from one end of the pressure cap 2. The card 22 is elastically engaged in the slot 11 to realize a detachable connection between the pressure cap 2 and the placement box 1. The structure is simple and easy to operate, which facilitates the placement and removal of samples, and thus facilitates the diagnosis of SSL.
[0031] In some embodiments, there is a gap between the bottom wall of the card slot 11 and the bottom of the card 22, so that the operator can reach into the card slot 11 to apply force to the bottom of the card 22, thereby facilitating the removal of the card 22 from the card slot 11, which in turn facilitates the removal of the cover 2.
[0032] Reference Figure 2 In some embodiments, the simplified sample packaging device further includes a pearl cotton sheet 3. A rectangular placement groove 12 is provided on the upper side of the placement box 1. The pearl cotton sheet 3 is placed in the placement groove 12, and the pearl cotton sheet 3 is higher than the placement box 1, so that the pearl cotton sheet 3 protrudes from the placement groove 12. When the sample is placed on the pearl cotton sheet 3, since the pearl cotton sheet 3 is higher than the placement box 1, the sample is compressed. More importantly, the cut surface of the sample has a high moisture content, so that the placed sample generates a slight adsorption force after contacting the pearl cotton sheet 3, which facilitates the flattening and fixing of the sample and improves the stability of the sample fixation.
[0033] In some embodiments, the upper side of the pearl cotton sheet 3 is uniformly provided with wavy texture 31 to increase the contact area of the sample, thereby improving the stability of the sample flattening and fixing.
[0034] In some embodiments, the upper side of the pearl cotton sheet 3 is provided with scale lines 32, which can measure the sample and thus facilitate the estimation of the sample size.
[0035] In some embodiments, the scale lines 32 are arranged in a cross shape to increase the placement area of the sample that can be measured and to enable the positioning of the sample.
[0036] In some embodiments, the scale line 32 is located at the center of the pearl cotton sheet 3, so that the sample is placed at the center of the pearl cotton sheet 3, so as to facilitate the placement of the sample and ensure sufficient contact with formalin.
[0037] The implementation principle of this embodiment is as follows: In practical application, the mucosal surface of the removed specimen (i.e., polyp) is flattened and placed in the placement box 1. Then, the pressure cap 2 is rotated, and the end of the pressure cap 2 away from the rotation is installed in the placement box 1 so that the pressure cap 2 presses the specimen tightly, quickly achieving flattening and fixation of the specimen. Afterward, the entire specimen is immersed in formalin, with the formalin contacting the specimen through multiple permeation holes 21. It can then be transported to the pathology department, or the cap can be opened directly for relevant pathological operations. This operation is simple and convenient. At the same time, it can solve the problems of curling and orientation disorder in sample fixation, ensuring that pathological slides can be sampled vertically, thereby improving the diagnostic accuracy of SSL.
[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
