Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a splicable nail plate and specimen storage system. Background Art

[0002] In medicine, in order to ensure the quality of the slices, the tissue blocks cut from hospital pathology specimens must be as flat as possible. In the process of obtaining tissue specimens for external examination in the pathology department, it is often necessary to unfold and pin some tissue specimens, such as cervical cone resection specimens, digestive tract surgery specimens, etc. Among them, the pinning board plays the role of supporting and pinning the specimens. Since different types of specimens vary greatly in size, diameter, length and other parameters, and most hospitals' pathology departments use nail boards with fixed areas and shapes, it is often difficult to select a suitable nail board according to the specific circumstances of the specimen. Small specimens (such as cervical cone resection specimens) are treated with large nail boards, while small nail boards cannot fully support larger and longer specimens (such as gastrointestinal surgery specimens). The former can cause waste of container space and reduce the number of specimens that the container can accommodate. The latter often forces external physicians to fold the intestine that exceeds the range of the nail board to the lower surface of the nail board for nailing. On the one hand, ordinary nail boards are flat and fold relatively violently, which can easily cause damage to the folded tissue and relative displacement of the internal relationship of the tissue. On the other hand, due to buoyancy, the lower surface of the nail board is often exposed above the formalin liquid surface. Therefore, the folded tissue specimens often have the risk of insufficient immersion and poor fixation, resulting in subsequent diagnostic difficulties.

[0003] In order to solve the problems existing in the above-mentioned technology to a certain extent, the utility model aims to propose a splicable nail board and specimen storage system, which can splice nail boards of suitable areas according to the specific circumstances of the specimen, and can splice oval nail boards with blunt turns when necessary, thereby reducing the risks of waste of container space, tissue damage, poor specimen fixation, etc. Utility Model Content

[0004] In order to overcome the above problems, the utility model provides a splicable nail board and specimen storage system to solve the shortcomings and defects of the existing nail boards, solve the problem of difficulty in matching the nail boards and specimens, and further solve the problem that the specimens cannot be completely immersed in formalin solution and the container space is wasted.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: a splicable nail plate, including a nail plate, an adsorption structure and a side displacement limiting structure are arranged on the side of the nail plate, the adsorption structure connects one or more nail plates to form a plane suitable for the area of ​​the specimen in the unfolded state, and one or more nail pins are nailed into the surface of the nail plate to fix the specimen in the unfolded state.

[0006] Furthermore, the nail plate is a rectangular structure or an arc-shaped structure, and its length and width are greater than its thickness.

[0007] Furthermore, the adsorption structure is a magnetic material coating or Velcro, which completely covers the four sides of the nail plate.

[0008] Furthermore, the side displacement limiting structure is a limiting hole and a limiting column, which limits the relative displacement between the sides of the nail plate in the connected state. The limiting hole is a circular hole, and the limiting column is a cylinder, and the length is equal to the sum of the depths of the two limiting holes.

[0009] Furthermore, the side displacement limiting structure is a limiting groove and a limiting strip, the limiting groove is a rectangular groove, and the limiting strip is a cuboid, the width of which is the sum of the depths of the two limiting grooves.

[0010] Furthermore, the tip of the nail needle is conical, the tail of the nail needle is a circular plane protruding upward, and the length of the nail needle is smaller than the thickness of the nail plate.

[0011] A specimen storage system comprises a container, wherein a splicable nail plate is arranged in the container, and a limiting column or a limiting strip is arranged on the inner wall of the container for fixing the splicable nail plate.

[0012] Compared with the existing solutions, the beneficial effects of the utility model are:

[0013] The utility model discloses a splicable nail board and specimen storage system, which, compared with similar products, will not cause vacant or wasted nail board area, thereby increasing the available area in the container and increasing the number of specimens that can be immersed in the container; different numbers and orientations of basic units can be selected for splicing according to the size of the specimens to form nail boards with suitable areas and shapes, so that large specimens can be fully flattened and unfolded, avoiding the phenomenon that specimens beyond the range of the nail board have to be folded to the lower surface due to insufficient nail board area, thereby exposing the specimens to the air.

[0026] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1 to Figure 10 As shown, the present embodiment provides a first embodiment of a splicable nail plate, comprising a nail plate 1, a suction structure 2 and a side displacement limiting structure 3 are arranged on the side of the nail plate 1, the suction structure 2 is used to connect one or more nail plates 1 to form a plane suitable for the area of ​​the specimen 4 in the unfolded state, and one or more nail pins 5 are nailed into the surface of the nail plate 1 to fix the specimen 4 in the unfolded state.

[0028] like Figure 1-2 As shown, the present embodiment provides an example of a specimen storage system, including a container 11, which is a cylinder body of 440 mm, 260 mm wide and 28.50 mm deep. A splicable nail plate is arranged in the container 11, and formalin solution 10 is injected into the container 11. The upper surface of the splicable nail plate faces downward, and a limiting column 8 is arranged on the inner wall of the container 11 to fix the splicable nail plate to be immersed below the liquid surface of the formalin solution 10, so as to realize long-term storage of the specimen 4.

[0029] Of course, the limiting strip 9 is provided on the inner wall of the container 11, which can also achieve the purpose of fixing the splicable nail plate immersed below the liquid surface of the formalin liquid 10, which is also within the protection scope of the present utility model.

[0030] like Figure 3-5 As shown in an embodiment 1, an adsorption structure 2 and a side displacement limiting structure 3 are provided on the four sides of the nail plate 1, the adsorption structure 2 completely covers the four sides of the nail plate 1, the adsorption structure 2 is a magnetic material coating or Velcro, and multiple nail plates 1 are adsorbed or bonded together by the side surfaces of two nail plates 1 through the adsorption structure 2. When multiple nail plates 1 are spliced ​​together, when collecting specimens 4, sometimes the sides of multiple nail plates 1 will undergo relative displacement changes under the action of gravity, affecting the work efficiency of medical staff and even damaging specimens 4. In order to avoid the occurrence of such problems, a side displacement limiting structure 3 is provided on the side of the nail plate 1.

[0031] like Figure 6 In the example 1 shown, the nail board 1 is a rectangular wooden board with a side length of 60mm*60mm and a height of 10mm. The area of ​​the cervical cone resection specimen 4 after unfolding is about 50mm*50mm. The specimen 4 can be flatly fixed on the upper surface of the nail board 1 using the nail pin 5. An adsorption structure 2 is set on the four sides of the nail board 1. The adsorption structure 2 is a magnetic material coating or Velcro, which completely covers the four sides of the nail board 1. The tip of the nail pin 5 is conical and can pass through the specimen 4 and then be nailed into the nail board 1, so that the specimen 4 in the unfolded state is tightly fixed on the surface of the nail board 1. The tail of the nail pin 5 is a circular plane that bulges upward. The length of the nail pin 5 is 8mm to avoid penetrating the nail board 1 and scratching medical staff.

[0032] like Figure 7 In the example 1 shown, the displacement limiting structure 3 on the side of the nail plate 1 is composed of two limiting holes 6 and two limiting columns 8, which can prevent the sides of the two nail plates 1 that are adsorbed or bonded together from relative displacement. The limiting hole is a circular hole with a diameter of 4 mm and a depth of 5 mm, which cooperates with the limiting column 8. The limiting column 8 is a cylinder with a diameter of 4 mm and a length of 10 mm.

[0033] like Figure 8 In the example 1 shown, the displacement limiting structure 3 on the side of the nail plate 1 is a limiting groove 7 and a limiting strip 9, which can prevent the sides of the two nail plates 1 that are adsorbed or bonded together from relative displacement. The limiting groove 7 is a rectangular groove with a length of 20 mm, a width of 4 mm, and a depth of 10 mm, and cooperates with the limiting strip 9. The limiting strip 9 is a rectangular parallelepiped with a length of 20 mm, a width of 4 mm, and a depth of 20 mm.

[0034] like Fig. 9 and 10 In the second example shown, the nail board 1 is an arc-shaped wooden board. After the specimen 4 is unfolded, it is fixed on the two nail boards 1 spliced ​​together. The two nail boards 1 are spliced ​​by setting adsorption structures 2 on the surrounding sides. The displacement limiting structure 3 limits the relative displacement of the sides of the two nail boards 1. The specimen 4 can be fixed flatly on the surface of the nail board 1 using nail pins 5. Adsorption structures 2 are set on the surrounding sides of the nail board 1. The adsorption structures 2 are magnetic material coatings or Velcro, which completely cover the four sides of the nail board 1. The tip of the nail pin 5 is conical, which can pass through the specimen 4 and then be nailed into the nail board 1, so that the specimen 4 in the unfolded state is tightly fixed on the surface of the nail board 1. The tail of the nail pin 5 is a circular plane that bulges upward.

[0035] Of course, nail plates 1 of different shapes spliced ​​together are also within the protection scope of the present utility model.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
