Description

Technical Field

[0001] This utility model belongs to the field of hard tissue pathological slide preparation technology, specifically relating to an embedding device that facilitates the fixation of hard tissue. Background Technology

[0002] In pathological examination techniques for biological tissues, bone tissue, as a hard tissue sample, contains a large amount of calcium and has a hard texture. Its preparation for pathological sections is complex, labor-intensive, and time-consuming. Currently, hard tissue sectioning techniques are widely used in the preparation of bone tissue sections without decalcification. Compared with traditional paraffin sectioning, it does not require decalcification and uses epoxy resin or methyl acrylate embedding agents for embedding. After preparation, pathological changes in the bone tissue can be observed under a microscope using staining and other techniques. The entire sectioning process includes paraformaldehyde fixation, graded ethanol dehydration, xylene clearing, infiltration embedding, hard tissue sectioning, deplasticization, and staining.

[0003] To easily obtain the desired cross-section, bone tissue is often embedded in a specific orientation, a process typically performed manually. The embedding and polymerization process is an irreversible chemical reaction, time-consuming, and prone to bubble formation and explosive polymerization. Tissue displacement is highly likely during this process, ultimately making sectioning difficult, requiring constant adjustments to the embedding block's orientation, or even failing to achieve the desired cutting surface, risking sample rejection.

[0004] During the embedding and solidification process, fixing biological bone tissue in the desired position and direction is the simplest and most direct method. Therefore, an embedding device that facilitates the fixation of hard tissue is provided to meet the above requirements. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an embedding device that facilitates the fixation of hard tissue.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] An embedding device for easy fixation of hard tissue includes an embedding layer with curling deformation function, and a plurality of fixing units are provided on one side of the embedding layer;

[0008] When the embedded layer is rolled into a ring, the fixing unit surrounds the hard tissue and compresses and fixes the hard tissue.

[0009] This invention uses the curling deformation of the embedding layer to drive the fixing unit to be distributed around the hard tissue, thereby squeezing and fixing the hard tissue. The embedding layer is placed in the embedding bottle to maintain the curled shape.

[0010] This fixation method is simple and convenient, and can fix biological bone tissue in the desired position and direction;

[0011] The embedding layer and fixing unit are made of polypropylene. Polypropylene has stable chemical properties, is not prone to chemical reaction with the embedding liquid, and has relatively soft physical properties, which makes it less likely to cause defects in the embedding block and will not affect subsequent processes such as cutting and deplasticizing.

[0012] The advantages of this invention are: the fixation method is simple and convenient, it can fix biological bone tissue in the desired position and direction, the embedding efficiency is high, and it is convenient to deal with embedding containers of different sizes and biological bone tissue of different sizes.

[0022] The technical solution of this utility model will be described in detail below with reference to specific embodiments and accompanying drawings. The embodiments described herein are specific implementations of this utility model, used to illustrate the concept of this utility model; these descriptions are explanatory and exemplary, and should not be construed as limiting the implementation methods or the scope of protection of this utility model. In addition to the embodiments described herein, those skilled in the art can employ other obvious technical solutions based on the content disclosed in the claims and specification of this application. These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein.

[0023] Example 1

[0024] like Figure 1 , 2 As shown in Figures 3 and 4, this embodiment provides an embedding device for easy fixation of hard tissue, including an embedding layer 1 with a curling deformation function, and a plurality of fixing units on one side of the embedding layer 1.

[0025] When the embedding layer 1 is rolled into a ring, the fixing unit surrounds the hard tissue and compresses and fixes the hard tissue.

[0026] In this embodiment, the curling deformation of the embedding layer 1 drives the fixing unit to be distributed around the hard tissue, and the hard tissue is squeezed and fixed. The embedding layer 1 is placed in the embedding bottle to maintain the curled shape.

[0027] This fixation method is simple and convenient, and can fix biological bone tissue in the desired position and direction;

[0028] The embedding layer 1 and the fixing unit are made of polypropylene. Polypropylene has stable chemical properties, does not easily react with the embedding liquid, and has relatively soft physical properties.

[0029] Example 2

[0030] like Figure 1 , 2 As shown, this embodiment provides an embedding device that facilitates the fixation of hard tissue. The difference from Embodiment 1 is that the fixing unit is a cone-shaped spike 2 disposed on one side of the embedding layer 1.

[0031] In this embodiment, when the embedding layer 1 is rolled up, the cone 2 surrounds the biological bone tissue and compresses and fixes the biological bone tissue.

[0032] To accommodate embedding bottles of different sizes, the cone-shaped spikes 2 can be trimmed to ensure that the length of the cone-shaped spikes 2 is appropriate. This prevents the cone-shaped spikes 2 from being too long, which would cause the embedding layer 1 to curl and result in an excessively large diameter, making it impossible to insert the embedding bottle.

[0033] To accommodate biological bone tissues of different shapes and sizes, the spikes 2 can be trimmed and removed so that they can conform to the surface of the compressed biological bone tissue.

[0034] Example 3

[0035] like Figure 3 , 4As shown, this embodiment provides an embedding device that facilitates the fixation of hard tissue. The difference from Embodiment 1 is that the fixing unit is an arc-shaped binding rib 3 disposed on one side of the embedding layer 1. When the embedding layer 1 is rolled into a ring, the arc-shaped binding ribs 3 in different columns overlap each other and form a binding ring. The number of columns of the arc-shaped binding ribs 3 is greater than or equal to two. The arc-shaped binding ribs 3 are provided with gear-shaped slots.

[0036] In this embodiment, multiple rows of overlapping circular arc-shaped binding ribs 3 are used to form a binding ring, thereby completing the fixation of the biological bone tissue. Specifically, as shown in the figure... Figure 4 In the example of two rows of circular arc binding ribs 3, the overlapping part of the circular arc binding ribs 3 forms a binding ring, and the biological bone tissue is in the binding ring. The two circular arc binding ribs 3 apply opposite forces to the biological bone tissue, thereby fixing the biological bone tissue in order to meet the needs of different embedding orientations.

[0037] The gear-shaped latches can be used to adjust the size of the restraint ring. The gear-shaped latches on adjacent arc-shaped restraint ribs 3 engage with each other to determine the size of the restraint ring. For example, the large restraint ring is 11mm to 8mm, the medium restraint ring is 8mm to 5mm, and the small restraint ring is 5mm to 2mm. For some special irregular biological bone tissues, stable fixation can be achieved by adjusting the size of the restraint ring.

[0038] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
