Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a puncture pathological sample embedding box. Background Art

[0002] In the medical field, puncture pathology specimens refer to tissue specimens collected by puncture, such as liver puncture, lung puncture, prostate puncture, etc. These specimens are usually collected by needle or puncture instrument to obtain tissue samples from specific parts of the body for pathological examination and diagnosis. The characteristics of puncture pathology specimens are that they are small in size, usually 5 to 20 mm in length, about 1 mm in thickness, relatively long in length, and need to maintain their integrity and morphology during the specimen dehydration process for subsequent pathological analysis and slice preparation.

[0003] At present, the dehydration process of pathological specimens is completed in an embedding box. However, the size of the outlet and inlet holes of the existing embedding box is large, and the puncture pathological specimens are easily leaked out and lost during the dehydration process; in addition, the space for accommodating puncture pathological specimens in the embedding box is large in the vertical direction, and the dehydration process will cause the specimen to curl and deform, and the embedding box cannot restrain it, which will cause the specimen to curl and deform after dehydration, which is not conducive to the subsequent production of sections.

[0004] Based on the existing embedding box, the puncture pathology sample is wrapped with filter paper, and the folding of the filter paper can solve the problem of the flatness of the puncture pathology sample to a certain extent. However, after the dehydration process of the filter paper in the dehydration instrument, it will be soaked with various reagents and paraffin and other components, resulting in adhesion, which will cause technical difficulties in the embedding process of the tissue after dehydration. In addition, the process of folding the filter paper itself also increases the difficulty and complexity of the operation.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the utility model, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0048] The inventor of this case has provided a solution to the problems existing in the prior art through careful and in-depth research. According to the shape characteristics of puncture pathology samples, the utility model provides a puncture pathology sample embedding box, including: a box body, having a first accommodating space, and the inner bottom surface of the box body has discharge holes arranged in an array; a box cover, which is pivotally connected to the box body, and the box cover has a sunken convex part on the side close to the first accommodating space, and the convex surface of the sunken convex part has inlet holes arranged in an array; wherein, when the box body and the box cover are closed, the sunken convex part is located in the first accommodating space, and the side of the sunken convex part contacts the inner side of the box body; a flat second accommodating space is formed between the convex surface of the sunken convex part and the inner bottom surface of the box body to place puncture pathology samples. The utility model can prevent puncture pathology specimens from leaking out of the embedding box and being lost, and prevent the samples from curling and deforming after dehydration.

[0049] The present invention is further described in detail below with reference to the accompanying drawings.

[0050] Figure 1 A schematic diagram showing the three-dimensional structure of a puncture pathology sample embedding box in an open state according to an embodiment of the utility model; Figure 2 A schematic diagram showing the side structure of a puncture pathology sample embedding box in a closed state according to an embodiment of the utility model; Figure 3 A schematic diagram of the side structure of a puncture pathology sample embedding box in an open state is shown according to an embodiment of the utility model.

[0051] refer to Figures 1 to 3 The utility model provides a puncture pathology sample embedding box, comprising: a box body 1 and a box cover 2.

[0052] In some embodiments, the box body 1 has a first accommodating space 11 inside to accommodate the puncture pathological sample 4. The bottom surface of the box body 1 has an array of discharge holes 12 to allow the dehydrated material and the embedding material to leave the first accommodating space 11.

[0053] In some embodiments, the box cover 2 is pivotally connected to the box body 1, and can be connected by a hinge, but the invention is not limited thereto. The box cover 2 has a sunken protrusion 21 on one side close to the first accommodating space 11, and an array of material feeding holes 22 are arranged on the convex surface of the sunken protrusion 21, so that the dehydrated material and the embedding material can enter the first accommodating space 11.

[0054] In some embodiments, when the box body 1 and the box cover 2 are closed, the sinking convex portion 21 is located in the first accommodating space 11 to reduce the height of the first accommodating space 11 for accommodating the puncture pathological sample 4 in the vertical direction to prevent the puncture pathological sample 4 from curling and deforming after dehydration. The side of the sinking convex portion 21 contacts the inner side of the box body 1 to completely close the first accommodating space 11 to avoid leakage and loss of the puncture pathological sample 4 during the dehydration process. A flat second accommodating space 3 is formed between the convex surface of the sinking convex portion 21 and the inner bottom surface of the box body 1 to specifically place the puncture pathological sample 4 and limit the curling and deformation of the puncture pathological sample 4 after dehydration. The size of the discharge hole 12 and the feed hole 22 is smaller than the puncture pathological sample 4 to avoid leakage and loss of the puncture pathological sample 4 during the dehydration process. In addition, the flat second accommodating space 3 can avoid the use of filter paper for the puncture pathological sample 4 during the dehydration process, prevent the puncture pathological sample 4 from adhering to the filter paper, and reduce the difficulty of using the filter paper during the dehydration process.

[0055] In some embodiments, the sinking convex portion 21 is in a terraced shape, and along a direction perpendicular to the bottom surface of the box body 1, the terraced surface area is reduced to form a flat second accommodation space 3. Further, the four sides of the sinking convex portion 21 are trapezoidal, and along a direction perpendicular to the bottom surface of the box body 1, the length of the bottom side of the trapezoid is reduced. At least one cross section of the sinking convex portion 21 perpendicular to the bottom surface of the box body 1 is trapezoidal, and along a direction perpendicular to the bottom surface of the box body 1, the length of the bottom side of the trapezoid is reduced. It is understandable that the sinking convex portion 21 can also be in a truncated cone shape, or other shapes, as long as it can form a flat second accommodation space 3.

[0056] In some embodiments, when the sunken protrusion 21 is in a terraced shape, the side of the sunken protrusion 21 is in line contact with the inner side of the box body 1. When the sunken protrusion 21 is in a rectangular shape, the side of the sunken protrusion 21 is in surface contact with the inner side of the box body 1. It is understandable that when the sunken protrusion 21 is in other shapes, it can have a corresponding contact mode with the inner side of the box body 1, and it is only necessary to completely close the first accommodating space 11 to prevent the puncture pathological sample 4 from leaking out and being lost during the dehydration process.

[0057] In some embodiments, the inner bottom surface of the box body 1 has a first fence 13, and the convex surface of the sunken protrusion 21 has a second fence 23. The first fence 13 and the second fence 23 cooperate with each other. When the box body 1 and the box cover 2 are closed, the first fence 13 and the second fence 23 are in surface contact to divide the second accommodation space 3 into a plurality of second sub-accommodation spaces 31. Each second sub-accommodation space 31 can be placed with a puncture pathology sample 4 to avoid mutual interference between multiple puncture pathology samples 4 during the dehydration process, thereby improving the dehydration efficiency of multiple puncture pathology samples 4. It is understandable that the first fence 13 and the second fence 23 can also be in line contact, or surface contact and line contact can be combined with each other, as long as the second sub-accommodation spaces 31 can be separated from each other.

[0058] In some embodiments, the first fence 13 and the second fence 23 are both in a cross shape to divide the second accommodation space 3 into four second sub-accommodation spaces 31. It is understandable that the first fence 13 and the second fence 23 can also be in a tic-tac shape to divide the second accommodation space 3 into nine second sub-accommodation spaces 31. The first fence 13 and the second fence 23 can also be in other shapes, as long as the second sub-accommodation space 31 can accommodate at least one puncture pathological sample 4.

[0059] In some embodiments, it is understood that the embedding box may not include a fence structure, that is, the bottom surface of the box body 1 does not have the first fence 13, and the convex surface of the sunken protrusion 21 does not have the second fence 23. In these embodiments, the bottom surface of the box body 1 is entirely the discharge hole 12, and the convex surface of the sunken protrusion 21 is entirely the input hole 22.

[0060] In some embodiments, during the dehydration and embedding process of the puncture pathological sample 4, the dehydration material and the embedding material enter the second accommodating space 3 from the feed hole 22 and leave the second accommodating space 3 from the discharge hole 12, so as to dehydrate and embed the puncture pathological sample 4 in the second accommodating space 3. It is understandable that during the transparent process of the puncture pathological sample 4, the transparent agent can also enter and leave the second accommodating space 3 from the feed hole 22 and the discharge hole 12. Or in other processes, the feed hole 22 and the discharge hole 12 can also be used for other purposes.

[0061] In some embodiments, the discharge hole 12 and the inlet hole 22 are circular and / or square. It is understandable that the discharge hole 12 and the inlet hole 22 can also be other shapes, such as rectangle, parallelogram, trapezoid or triangle, etc., as long as the size is smaller than the puncture pathological sample 4 to avoid leakage and loss of the puncture pathological sample 4 during the dehydration process.

[0062] In some embodiments, the box body 1 has a snap-fit ​​hole 14, and the box cover 2 has a snap-fit ​​portion 24. When the box body 1 and the box cover 2 are closed, the snap-fit ​​hole 14 and the snap-fit ​​portion 24 cooperate with each other to close the embedding box, but the present invention is not limited thereto.

[0063] In some embodiments, the box cover 2 has an opening and closing portion 25 to open or close the embedding box. The projection of the opening and closing portion 25 on the bottom surface of the box body 1 is separated from the projection of the first accommodating space 11 on the bottom surface of the box body 1, but the specific position relationship between the two is not limited to this.

[0064] In some embodiments, the material of the biopsy pathology sample embedding box of the present invention can be polyoxymethylene (POM), but is not limited thereto. POM has the advantages of excellent mechanical properties, strong wear resistance, high chemical stability, good high temperature resistance and high dimensional stability. The biopsy sample embedding box made of POM material can effectively protect the biopsy pathology sample 4 and provide stable support and protection during the section preparation process such as dehydration and embedding.

[0065] In some embodiments, the outer dimensions of the box body 1 of the puncture pathology sample embedding box are 40×28×6mm, wherein the dimensions of the first internal accommodation space 11 of the box body 1 are 38×26×5mm. The apertures of the discharge hole 12 and the feed hole 22 are less than 0.5mm. The sinking height of the sunken protrusion 21 of the box cover 2 is 4mm, so that the height of the second accommodation space 3 is 1mm, which matches the thickness of the puncture pathology sample 4. The cross section of the box cover 2 perpendicular to the inner bottom surface of the box body 1 is trapezoidal, with an upper side of 29mm, a lower side of 27mm, and a height of 4mm, i.e., the sinking height of the sunken protrusion 21. In this case, the dimensions of the second accommodation space 3 are 38×26×1mm. The dimensions of the second sub-accommodation space formed by the cross-shaped first fence 13 and the second fence 23 are 8×6×1mm.

[0066] In summary, according to the shape characteristics of the puncture pathology sample, the puncture pathology sample embedding box provided by the utility model can (1) prevent the puncture pathology specimen from leaking out of the embedding box and being lost by reducing the size of the discharge hole and the inlet hole to be smaller than the puncture pathology sample; and (2) prevent the puncture pathology specimen from curling and deforming after dehydration and prevent the specimen from sticking to the filter paper by reducing the height of the space in the embedding box to accommodate the sample in the vertical direction and avoiding the use of filter paper.

[0067] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
