Description

Technical Field

[0001] This utility model relates to the fields of biotechnology and new medicine, and in particular to a retractable, efficient, and high-precision tissue shear. Background Technology

[0002] Existing tissue processing methods mostly rely on traditional manual scissor cutting. This method causes significant damage to the surrounding tissue cells and results in small tissue blocks of varying sizes and shapes, greatly impacting subsequent experiments. This design optimizes this time-consuming and labor-intensive method, reducing tissue waste. In terms of practicality, this design can replace traditional methods in domestic research in the same field, greatly improving work efficiency and promoting the output of high-tech research results. Because it involves high-precision tissue processing, requiring tissue blocks with dimensions of 1mm, the material, size, thickness, and operational efficiency of the instrument's components are crucial. Therefore, how to accurately and quickly shear high-precision tissue is a pressing technical problem that needs to be solved. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a retractable, efficient, and high-precision tissue cutter for precise and rapid cutting of high-precision tissues.

[0004] The present invention adopts the following technical solution:

[0011] Preferably, in the above-mentioned retractable, high-efficiency, and high-precision tissue cutter, one end of the transverse blade is provided with a push-pull handle, the size of which is larger than the size of the transverse blade.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Unlike traditional physical cutting methods that require manual pre-processing of tissue into blocks followed by microscopic division into approximately 1mm long organoid precursor pieces using small scissors, this invention presents a retractable, efficient, and high-precision tissue cutter. This solves the problems of complex tissue processing procedures and the insufficient precision, time-consuming, and labor-intensive nature of manual cutting. Freshly obtained tissue blocks can be directly placed into the tool, and a high-precision, multi-piece set of perfect organoid precursors can be obtained in just two steps.

[0025] The present invention will now be further described with reference to the accompanying drawings.

[0026] This utility model embodiment provides a retractable, efficient, and high-precision tissue cutter, such as... Figure 1 As shown, this retractable, high-efficiency, and high-precision tissue cutter includes a top cover 1, a support plate 2, and a cross-section blade 3. Figure 2 As shown, the lower end of the upper cover 1 is provided with a cutting component 4, the upper end of the support plate 2 is open, and the side wall of the support plate 2 is provided with a transverse blade 5. The support plate 2 is used to hold tissue samples. The upper cover 1 can cover the upper end opening of the support plate 2. The cutting component 4 is used to cut the tissue samples of the support plate 2. The transverse blade 3 is used to extend into the support plate 2 through the transverse blade 5 to cut the tissue samples.

[0027] In practice, the tissue sample is placed in the support plate 2. First, the transverse blade 3 is inserted into the support plate 2 through the transverse cutting edge 5 to cut out the tissue sample at a preset height, which is the distance between the transverse cutting edge 5 and the bottom of the support plate 2. Then, with the transverse blade 3 in the inserted state, the excess tissue removed from the upper part of the transverse blade 3 is taken out. Then, the transverse blade 3 is taken out, the upper cover 1 is covered, and the tissue sample after preliminary cutting is further cut by the cutting component 4 at the lower end of the upper cover 1 to obtain tissue particles of a set size. Finally, the upper cover 1 is taken out, completing the high-precision shearing of the tissue sample.

[0028] It should be noted that when this retractable, high-efficiency, and high-precision tissue cutter is not in use, its state can be as follows: Figure 1 As shown, to facilitate the storage of this retractable, efficient, and high-precision tissue cutter, during use, the upper cover 1 and the cross-section blade 3 are removed from the support plate 2, and then the operation is performed as described above. After obtaining high-precision tissue particles, the upper cover 1, support plate 2, and cross-section blade 3 are cleaned and dried, and then reassembled as shown. Figure 1 The state shown is ready for use.

[0029] In some embodiments, such as Figure 3 As shown, there are multiple transverse cutting edges 5 and multiple transverse cutting blades 3, and the number of transverse cutting blades 3 is equal to the number of transverse cutting edges.

[0030] In this embodiment, there are three transverse cutting edges 5 and three transverse cutting blades 3. It is understood that the number of transverse cutting edges 5 and three transverse cutting blades 3 here is just an example and does not constitute a limitation on this utility model.

[0031] When multiple transverse blades 5 are present, it is particularly suitable for cutting tissue samples with greater height, which refers to tissue samples that can be cut into at least three layers that meet the size requirements. In specific implementation, after the tissue sample is placed in the support tray 2, a cross-section blade 3 is first inserted into the transverse blade 5 at the highest position. Then, the tissue sample above the cross-section blade 3 is removed and the cross-section blade 3 is taken out. Subsequently, a cross-section blade 3 is inserted into the transverse blade 5 at the middle position. The top cover 1 is then closed, and a batch of tissue particles is obtained. After removing the cut tissue particles, the cross-section blade 3 at the middle position is removed, and a cross-section blade 3 is inserted at the lowest position. The above operation is repeated to complete the cutting of the tissue sample with greater height.

[0032] It should be noted that the above example illustrates the cutting operation when three transverse blades 5 are set. When more blades are set, such as 4, 5, 6 or more, the cutting operation method is to insert the transverse blades 3 sequentially from top to bottom to perform the corresponding operation, thereby obtaining multiple batches of tissue particles of the same size.

[0033] In some embodiments, such as Figure 2 As shown, a sample groove 6 is provided at the bottom of the support plate 2. The sample groove 6 is for convenient placement of tissue samples. The upper end of the sample groove 6 is flush with the horizontal cutting edge 5 in the horizontal direction. The height of the sample groove 6 is determined according to the height of the tissue sample to be cut. For example, if the height of the tissue particles to be cut is h mm, then the height of the sample groove 6 is set to h.

[0034] In some embodiments, such as Figure 4 As shown, a handle 7 is provided at the upper end of the cover 1 to facilitate operation of the cover 1.

[0035] In some embodiments, such as Figure 4 As shown, the cutting assembly 4 includes a blade head 41. One end of the blade head 41 is fixed to the lower end of the upper cover 1, and the other end of the blade head 41 is provided with a blade groove 42. Multiple dividing blades 43 are provided in the blade groove 42 to divide the blade groove 42 into multiple cutting grooves 44. At least two cutting blades 45 are evenly distributed in the cutting grooves 44.

[0036] In this embodiment, the main function of the cutting component 4 is to further cut the tissue sample that has already been cut by the cross-section blade 3. After being cut by the cross-section blade 3, the tissue sample has formed a tissue sample of a preset height. The cutting purpose of the cutting component 4 is to cut the tissue sample in length and width to obtain tissue particles of a preset size. Specifically, when the upper cover 1 is placed on the upper end of the support plate 2, the cutting component 4 is pressed down, and the multiple cutting blades 45 and the dividing blades 43 in the cutting groove 44 complete the cutting. The end face of the blade groove 42 that contacts the tissue sample can also be set as the cutting surface. Therefore, adjacent cutting blades 45, together with the dividing blades 43 or the blade groove 42, can form several square cutting grooves. The length and width of the square cutting grooves are determined according to the preset size of the tissue particles.

[0037] In some embodiments, in the above-mentioned retractable, high-efficiency, and high-precision tissue cutter, a push-pull handle 8 is provided at one end of the transverse blade 3. The size of the push-pull handle 8 is larger than the size of the transverse blade 5. The push-pull handle 8 facilitates the operation of the transverse blade 3 on the one hand, and avoids inserting the transverse blade 3 completely into the carrier plate 2 on the other hand, so as to facilitate the subsequent removal of the transverse blade 3.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
