[0035] See also Figure 1-Figure 9 , the utility model provides the following technical solutions:

[0036] Embodiment 1: After the patient's lymph nodes are cut, a device is needed to store them for later detection and evaluation. The working principle is as follows: Figure 1 , Figure 2 , Figure 6 and Fig. 9 As shown:

[0037] A lymph node extractor comprises a device body 1 and a cryopreservation tube 3, wherein the inside of the device body 1 is provided with receiving grooves 5 at equal intervals, and the inside of the receiving grooves 5 is provided with the cryopreservation tube 3, and the lower surface of the cryopreservation tube 3 is provided with an annular groove 4, a spring 6 is fixedly connected to the inside of the receiving groove 5 of the device body 1, and the other end of the spring 6 is fixedly connected to an arc-shaped clamping block 7, and dividing lines 8 are evenly spaced on the surface of the device body 1; the arc-shaped clamping block 7 forms an elastic structure with the device body 1 through the spring 6, and a rubber pad is glued to the surface of the arc-shaped clamping block 7.

[0038] When the user uses the device, he first stores the gastric cancer tissue sample and the adjacent normal tissue sample in the cryopreservation tube 3, and then inserts the cryopreservation tube 3 into the receiving groove 5. The arc-shaped clamping block 7 inside the receiving groove 5 is squeezed by the cryopreservation tube 3 and moves outward, and the spring 6 will be deformed. The repulsive force generated by the deformation will cause the arc-shaped clamping block 7 to clamp the outer wall of the cryopreservation tube 3. The surface of the arc-shaped clamping block 7 is glued with a rubber pad to play a protective role.

[0039] Embodiment 2: The technical content disclosed in this embodiment is a further improvement made on the basis of the above embodiment 1. After the existing extraction bags classify the lymph nodes in various tissues, the staff needs to mark and classify each group of extraction bags with a pen, which is troublesome and inconvenient. In order to solve this technical problem, Figure 1-Figure 7 As shown:

[0040] The rear surface of the device body 1 is fixedly connected with a base 9 at equal intervals, and a marking structure is arranged inside the base 9, and the base 9 marks and classifies the cryopreservation tubes 3 through the marking structure; the marking structure is provided with a label column 12, a sliding groove 10 is provided inside the left side of the base 9, and a first sliding rod 11 is slidably connected inside the sliding groove 10, and the other end of the first sliding rod 11 is fixedly connected with the label column 12, and the other end of the label column 12 is fixedly connected with a second sliding rod 13, and at the same time, the end of the second sliding rod 13 away from the label column 12 is fixedly connected with a hexagonal block 14, and the right side of the base 9 is provided with an inner hexagonal slot 15; the sliding groove 10 is slidably connected to the first sliding rod 11, and the second sliding rod 13 is slidably connected to the base 9, the inner hexagonal slot 15 and the hexagonal block 14 constitute a snap-fit ​​structure, and the inner hexagonal slot 15 and the hexagonal block 14 are regular hexagons when viewed from the side; the label column 12 is a regular hexagon when viewed from the side, and the material of the label column 12 is a white high-gloss plate.

[0041] A label column 12 is provided. The label column 12 is a regular hexagon in side view and has six faces. The user can write and mark on it with an erasable black pen. The material of the label column 12 is a white high-gloss plate, which is convenient for wiping and changing the label later. The dividing line 8 of the device body 1 divides the device into six areas. The user can classify the labels of each area as needed, which is convenient for the user to distinguish;

[0042] The label column 12 can rotate. The user pulls out the hexagonal block 14 and then rotates the hexagonal block 14, thereby rotating the second sliding rod 13. The rotation of the second sliding rod 13 drives the label column 12 to rotate. According to the use requirements, the corresponding label can be turned to the top, and then the hexagonal block 14 is pushed back to fix the label column 12 with the inner hexagonal slot 15.

[0043] By writing a label on the label column 12 in advance, the label is generally the name of a certain part of the body. When using it, the user only needs to rotate the label column 12 so that the corresponding label faces upward. The user does not need to frequently use a marker to mark and classify each bag, thereby achieving a convenient effect and saving time and effort.

[0044] Embodiment 3: The technical content disclosed in this embodiment is a further improvement based on the above-mentioned embodiments 1 and 2. Although the device can clamp and fix the extraction tube, the extraction tube may still fall off from the device during the movement and transportation. In order to solve this technical problem, Figure 1 , Figure 2 , Figure 5 , Figure 6 and Fig. 9 As shown:

[0045] The inside of the device body 1 is rotatably connected with a rotating rod 16 at equal intervals, and a fixed structure is provided below the rotating rod 16, and the rotating rod 16 is clamped and fixed to the freezing tube 3 through the fixed structure; the fixed structure is provided with a fixed block 2, and the bottom end of the rotating rod 16 is fixedly connected with a first bevel gear 17, the inside of the device body 1 is rotatably connected with a screw rod 19, and the left end of the screw rod 19 is fixedly connected with a second bevel gear 18, and the left side of the screw rod 19 is threadedly connected with the fixed block 2, and the fixed block 2 is slidably installed in the device body 1; the first bevel gear 17 is meshed with the second bevel gear 18, the rotating rod 16 is rotatably connected to the device body 1, the screw rod 19 is threadedly connected to the fixed block 2, and the fixed block 2 and the annular groove 4 constitute a sliding structure, and the fixed block 2 is slidably connected to the device body 1.

[0046] When the user inserts the cryotube 3 into the receiving groove 5, the arc-shaped clamping block 7 clamps the outer wall of the cryotube 3 and is provided with a fixing structure;

[0047] The user rotates the rotating rod 16, thereby rotating the first bevel gear 17, and the rotation of the first bevel gear 17 drives the second bevel gear 18 to rotate, thereby rotating the screw rod 19, and the rotation of the screw rod 19 causes the fixing block 2 to move outward. The fixing block 2 will be inserted into the annular groove 4 of the cryogenic tube 3, thereby performing secondary fixation on the cryogenic tube 3 to prevent the cryogenic tube 3 from falling off and tilting, thereby improving the stability of the device.
