Embodiment 1

[0074] Figure 15 A schematic diagram of the three-dimensional structure of a preferred embedding cassette is provided. From Figure 15 It can be seen that the embedding cassette of this embodiment is made of figure 2 , 5 , 12 and 14 embedding frames, extrusion fasteners, two slideways and two clamping fixtures. The extrusion fastener 4 is mated with the groove 33 on the parallel inner surface of the extrusion frame 32 through the guidance of the ribs I 41 on the two parallel sides. On the outer side of the flat bottom surface of the extruding fastener 4, there are two slideways 5 arranged in parallel to form a groove for the two clamping and fixing pieces 6 to be connected. Two clamping fixtures 6 are arranged between the two slideways 5, one of which is fixedly connected with the slideways, and the other is slidably connected. The two fixing surfaces 62 of the clamping fixture 6 are oppositely arranged to form a clamping structure for clamping biological tissue.

Embodiment 2

[0077] Figure 16 It is a preferred depth adjustment stabilizer of the embedding cassette in the present invention. From Figure 16 It can be seen that the depth adjustment stabilizer 7 is a square frame structure, and a set of drain grooves are arranged in a linear array on the four sides. Ridges II 71 are provided on the outer sides of the two parallel vertical surfaces. The rib II 71 can be fixedly connected with the embedding frame 3 .

Figure 18 for Figure 17 A schematic diagram of the three-dimensional structure of the embedding cassette from another angle. From Figure 17 and Figure 18 It can be seen that the embedding box has a Figure 4 Embedding frame 3 shown, two Figure 8 Slideway 5 is shown, together with a clamping fixture 6 with retaining pin 63 and a depth adjustment stabiliz...

Embodiment 3

[0081] Figure 19 It is a schematic diagram of the three-dimensional structure of the third preferred embedding cassette provided by the present invention. The embedding cassette is composed of a figure 2 The embedding frame 3 and a Figure 5 The extrusion fastener 4 shown is composed of two embedded filter paper strips (not shown) arranged vertically. Wherein, the bottom outer surface of the clamping fastener 4 is the biological tissue bearing surface. The filter paper belt is clamped and fixed by the extruding frame 32 and the convex rib I 41, and forms a pocket fixing space with it on the biological tissue bearing surface.

Abstract

The invention discloses a multifunctional integrated tissue embedding box and belongs to the technical field of medical apparatus and instruments. The multifunctional integrated tissue embedding box comprises an embedding frame body and an extruding fastener, wherein the embedding frame body is provided with an extruding frame at the bottom; the extruding fastener is in sliding fit or interferencefit connection with an inner side surface of the extruding frame of the embedding frame body through a side surface; a right-angle or forked tail slide rail is arranged on the surface of the extruding frame of the embedding box; the extruding fastener is adopted for extruding and fixing a to-be-treated sample, so as to effectively prevent the sample from skewing and dumping during the treatment processes of dehydration, waxing, and the like; and a flange I of the side surface of the extruding fastener can be in fitting connection or interference fitting with a groove in the extruding frame, so as to select a proper fixing position. According to the multifunctional integrated dehydration embedding box, in spite of size, samples, including puncturing tissues, are positioned in the embeddingbox and are directly embedded after conventional dehydration without taking out. The multifunctional integrated tissue embedding box has the advantages that tiny tissues can not be lost; capsule walltissues do not fall or tilt; large and medium tissue blocks do not displace; no error occurs; and errors can be avoided.

Description

technical field [0001] The invention relates to a multifunctional integrated tissue embedding box, which belongs to the technical field of medical instruments. Background technique [0002] Paraffin section is the most widely used method in routine histological preparation techniques. Paraffin section can not only be used to observe the morphological structure of normal cell tissue, but also the main method used in pathology and forensic science to study, observe and judge the morphological changes of cells. The traditional paraffin sectioning method includes more than ten steps such as material collection, fixation, washing and dehydration, transparency, wax immersion, embedding, sectioning and patching, and dewaxing. And existing biological tissue slices all adopt automatic tissue dehydrator. The specific steps are: after the biological tissue is dehydrated, it is embedded with a biological tissue paraffin embedding machine. First, remove the lid of the embedding casset...
