Description

Technical Field

[0001] The present invention relates to the technical field of tumor sample storage, and particularly relates to a sample storage device for tumor detection. Background Art

[0002] With the continuous progress of medical technology, the means and methods of tumor sample detection have become increasingly rich and accurate. From traditional pathological examinations to modern molecular biology and genetics detections, tumor sample detection has become an indispensable part of tumor diagnosis and treatment. In addition, the improvement of people's health awareness and the increase in medical needs have also promoted the continuous development and improvement of tumor sample detection technology. The reason for tumor sample detection is that it can provide doctors with key information about tumor type, malignancy, growth rate, and whether it has spread, which is crucial for formulating personalized treatment plans, evaluating treatment effects, and predicting the prognosis of patients. At the same time, tumor sample detection also helps to discover new tumor markers and treatment targets, promoting the development of tumor research.

[0003] Tumor samples, such as tissue or cell samples, need to be properly preserved after collection to maintain their stability and biological activity. This is because the cell structure and molecular characteristics in the sample can be relatively stably maintained under appropriate preservation conditions, which helps to reduce DNA degradation and protein denaturation. This stability is crucial for subsequent molecular biology detections, pathological analyses, etc., and can ensure the accuracy and reliability of detection results.

[0004] Some existing sample storage devices for tumor detection clamp the corresponding test tubes through a jaw structure and place them into a storage box, and perform low-temperature preservation treatment through a cryogenic machine. Most of these devices require manual operation according to strict operating procedures to access and store tumor samples. The operation processes of these devices are not only relatively complex, but also have relatively single functionality. The accuracy of their operation is greatly affected by the proficiency of the operator. For some operators who are not proficient in operation, the complexity of the operation steps of these devices is relatively high, and it is easy to cause non-standard operations during operation, affecting the detection accuracy of subsequent tumor samples.

[0005] Therefore, the present invention proposes a sample storage device for tumor detection to solve the above problems. Summary of the Invention

[0006] To solve the above problems, the present invention provides a sample storage device for tumor detection, which intelligently processes the storage and retrieval operations of tumor detection samples after they are loaded into test tubes, reduces the operation difficulty of this process, and improves the convenience of storage and retrieval.

[0007] To achieve the above object, the technical solution of the present invention is as follows: A sample storage device for tumor detection, including a storage box and test tubes. The inner top wall of the storage box is provided with a clamping component for clamping test tubes. The surface of the storage box is provided with a control panel. The bottom of the storage box is internally provided with a cryogenic machine communicated with the inner cavity of the storage box. One side of the storage box is fixedly connected with a tool box. Inside the tool box, a number of placement plates slidably matched with the inner wall of the tool box are evenly distributed from top to bottom. At the upper ends of the placement plates, a number of placement components for storing test tubes are placed. On one side of the bottom of the storage box, a storage slot and a taking slot are symmetrically arranged. The inner top walls of the storage slot and the taking slot are both provided with openings communicating with the inside of the storage box. At the inner bottoms of the storage slot and the taking slot, a first lifting component and a second lifting component for lifting the placement components are respectively arranged. Inside the storage box, a heat preservation box is installed. On one side of the heat preservation box, a number of heat preservation cavities are linearly arranged from top to bottom. Inside the heat preservation cavities, electric control telescopic plates slidably matched with the inside of the heat preservation cavities are arranged;

[0008] The cryogenic machine, the first lifting component, the second lifting component, and the electric control telescopic plate are all electrically connected to the control panel;

[0009] The control panel includes a detection unit and an interaction unit;

[0010] The detection unit is used to detect the temperature inside the storage box; it is also used to obtain the image information of the placement components placed on each electric control telescopic plate, generate the coordinate information of each placement component, label each placement component, and output the corresponding comprehensive information;

[0011] The interaction unit is used to display the three-dimensional image of the internal components of the storage box, and based on the comprehensive information output by the detection unit, display the temperature inside the storage box in the three-dimensional image, and display the three-dimensional models of the placement components on each placement plate of each layer. On the three-dimensional model of each placement component, the corresponding saved time and model label are marked; it is also used for the operator to select the placement component to be taken, and take out the selected placement component through the clamping component; it is also used to place the placement component to be stored at a certain position of a certain electric control telescopic plate selected by the operator through the clamping component.

[0012] Principle of the basic solution: The test tubes to be stored are placed and fixed through the placement components, and then the placement components are placed on the second lifting component. The control panel controls the second lifting component to send the placement components into the storage box, and then the clamping component is used to clamp the placement components, move and place them on the preset extended or manually selected extended electric control telescopic plate. After the placement is completed, the electric control telescopic plate retracts to complete the storage operation; when taking, the operator selects the placement component to be taken through the interaction unit, clamps and moves the placement component to directly above the first lifting component, and then places it on the first lifting component. The first lifting component sends the placement component out of the storage box to complete the taking work.

[0013] The above - mentioned solution has the following beneficial effects:

[0014] 1. Compared with the prior art, in this solution, through the interaction unit of the control panel, the operator can intuitively see the situation inside the storage box, including information such as temperature and the positions of the placement components (test tubes). This greatly reduces the operation difficulty. Through the interaction unit and the detection unit of the control panel, real - time monitoring and intelligent processing of the situation inside the storage box are achieved. The operator can select the required placement components or specify the storage positions through simple operations, greatly improving the work efficiency.

[0015] 2. In this solution, the test tube is not directly clamped by the clamping component. Instead, the placement component first fixes it therein, and then the clamping component clamps the placement component for the storage and retrieval of the test tube. This can not only reduce the possibility of damage to the test tube by the clamping component when directly clamping the test tube, but also provide the stability of the clamping component when the test tube is replaced with the placement component.

[0016] Furthermore, the clamping component includes a moving guide rail arranged on the inner top wall of the storage box. The moving guide rail is slidably fitted with a moving seat electrically connected to the control panel. The bottom end of the moving seat is fixedly connected to a three - axis robotic arm signal - connected to the control panel. The placement plates are all within the movement track of the three - axis robotic arm.

[0017] Beneficial effect: The introduction of the three - axis robotic arm greatly improves the operation accuracy and flexibility. Due to having three degrees of freedom, the three - axis robotic arm can accurately reach any position inside the storage box, clamp and move the placement component without manual intervention. This not only improves the work efficiency but also reduces the error during the operation process.

[0018] Furthermore, the first lifting component includes a first electric control lifting frame. One end of the first electric control lifting frame is arranged at the bottom of the taking slot, and the other end of the first electric control lifting frame is fixedly connected to a first lifting platform; the second lifting component includes a second electric control lifting frame. One end of the second electric control lifting frame is arranged at the bottom of the storage slot, and the other end of the second electric control lifting frame is fixedly connected to a second lifting platform; both the first electric control lifting frame and the second electric control lifting frame are electrically connected to the control panel; both the first electric control lifting frame and the second electric control lifting frame adopt a double - layer X - type articulated folding structure.

[0019] Beneficial effect: The design of the double - layer X - type articulated folding structure makes the lifting frame more stable during the lifting process, reducing the possibility of shaking and tilting. This helps to ensure the safety of the placement component during the lifting process and avoid damage due to shaking. The lifting frame can be folded up after the lifting is completed to save storage space.

[0020] Furthermore, the placement components all include placement blocks and controllers disposed inside the placement blocks. Grooves are formed at the tops of the placement blocks, and placement slots for storing test tubes are formed at the central positions of the bottoms of the grooves. Airbag rings close to the bottoms of the grooves are fixedly connected to the inner walls of the placement slots. Telescopic cavities corresponding to the placement slots are arranged at the inner bottoms of the placement blocks. Pistons slidably engaged with the inner walls of the telescopic cavities are arranged in the telescopic cavities. Connecting rods slidably connected to the placement blocks are fixedly connected to the tops of the pistons. The tops of the connecting rods all extend into the placement slots and are fixedly connected to hemispherical pressure seats. A number of first springs are fixedly connected to the outer surfaces of the pressure seats, and the other ends of the first springs are all fixedly connected to the inner walls of the placement slots. Ventilation channels communicating with the airbag rings are formed at the bottoms of the telescopic cavities; Magnetic attraction layers are fixedly connected to the bottoms of the pistons, and first electromagnets corresponding to the magnetic attraction layers are fixedly connected to the inner bottom walls of the telescopic cavities. The first electromagnets are all electrically connected to the controller. First buttons for controlling the on / off of the first electromagnets are arranged at the tops of the placement blocks.

[0021] Beneficial effects: Through the dual buffering effects of the airbag rings and the first springs, as well as the fixing effects of the pistons and the first electromagnets, the placement components can ensure the stability and safety of the test tubes during storage. Even when the external environment changes or is slightly vibrated, the test tubes can remain stable and immobile.

[0022] Furthermore, a number of docking components for docking adjacent placement blocks are arranged on the side surfaces of the placement blocks close to the bottoms. The docking components all include docking grooves formed on the surfaces of the placement blocks. A second electromagnet, a magnetic attraction plate, and a number of second springs are respectively arranged in the docking grooves from left to right. The second electromagnets are all fixedly connected to the inner walls of the docking grooves. The magnetic attraction plates are all slidably connected to the inner walls of the docking grooves. One ends of the second springs are all fixedly connected to the magnetic attraction plates, and the other ends of the second springs are all fixedly connected to the inner walls of the docking grooves. The second electromagnets are all electrically connected to the controller. A number of second buttons corresponding to the second electromagnets are arranged on the side surfaces of the placement blocks close to their tops. When the second buttons are pressed, the second electromagnets are powered off, and vice versa, the second electromagnets are powered on.

[0023] Beneficial effects: Through the splicing function, users can flexibly combine the number and arrangement of the placement blocks according to actual needs, thereby making full use of the storage space. This is especially applicable to scenarios where a large number of test tubes need to be stored, effectively improving the utilization rate of the storage space. By setting the second buttons to control the on / off of the second electromagnets, the splicing and separation of the placement blocks can be easily achieved when clamped by the three-axis robotic arm. This design simplifies the operation steps and improves the operation convenience.

[0024] Furthermore, a number of through holes are formed on the surfaces of the magnetic attraction plates.

[0025] Beneficial effects: When the second electromagnet is powered off, the magnetic attraction plate moves due to the action of the second spring, thereby squeezing the internal air and discharging it through the through holes, thus cleaning the dust in the docking groove.

[0026] Further, a protective case is hinged inside the groove.

[0027] Beneficial effects: When in the closed state, the protective case can closely fit the groove, effectively preventing pollutants such as dust and stains from entering the inside of the groove and keeping the test tube clean and hygienic.

[0028] Further, a first partition board and a second partition board are respectively arranged in the storage slot and the picking slot.

[0029] Beneficial effects: The first partition board and the second partition board not only play a role in isolation, but also can provide a certain degree of protection for the samples. During storage, even in case of accidental collision or dropping, the partition boards can effectively absorb the impact force and reduce the risk of sample damage. At the same time, the partition boards can also prevent pollutants such as dust and stains from entering the storage slot and the picking slot, keeping the samples clean and hygienic.

[0030] Further, the control panel further includes a temperature control unit, and the temperature control unit is used to adjust the output power of the cryogenic machine based on a preset storage temperature.

[0031] Beneficial effects: The temperature control unit can automatically adjust the output power of the cryogenic machine based on a preset storage temperature. This precise temperature control mechanism helps to ensure that the samples are always stored at the optimal storage temperature, avoiding sample deterioration or inactivation caused by temperature changes.

[0032] Further, the specific operation steps are as follows:

[0033] Step 1: Take out the placement block placed in the toolbox, open the protective case, place the test tube containing the tumor sample to be stored in the placement slot, and after fixing, close the protective case;

[0034] Step 2: Place the placement block with the test tube on the second lifting platform, and then lift the second lifting platform by the second electric control lifting frame. Send the placement block with the test tube into the storage box, and then grab the placement block by the three-axis robotic arm and lift it to the placement origin and push out the corresponding electric control telescopic plate. Place the placement block in the designated area, and then the electric control telescopic plate retracts;

[0035] Step 3: When taking, select the placement block to be taken through the control panel, clamp the placement block by the three-axis robotic arm, move it directly above the first lifting platform, place the placement block on the first lifting platform, and then the first lifting platform descends. After reaching the position, take out the placement block. Open the protective case and press the first button to disconnect the first electromagnet, and the first spring resets. The test tube is lifted to a corresponding height from the placement slot, facilitating the operator to take it.

[0047] The following is a further detailed description through specific embodiments:

[0048] Embodiment 1:

[0049] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 : A sample storage device for tumor detection, including a storage box 2 and test tubes. A clamping component for clamping the test tubes is provided on the inner top wall of the storage box 2. A control panel is provided on the surface of the storage box 2. A tool box 1 is fixedly connected to one side of the storage box 2. A plurality of placement plates 6 that are slidably engaged with the inner wall of the tool box 1 are evenly distributed from top to bottom inside the tool box 1. A plurality of placement components for storing test tubes are placed on the upper ends of the placement plates 6. A storage groove 9 and a taking groove 8 are symmetrically provided at the bottom of one side of the storage box 2. Through openings communicating with the inside of the storage box 2 are opened on the inner top walls of the storage groove 9 and the taking groove 8. Since the inside of the storage box 2 can communicate with the outside through the through openings of the storage groove 9 and the taking groove 8, a first isolation plate 3 and a second isolation plate are respectively provided in the storage groove 9 and the taking groove 8. Thus, when the test tubes are stored, the communication between the inside of the storage box 2 and the outside is blocked by closing the first isolation plate 3 and the second isolation plate, reducing the circulation of outside air directly through the two through openings and the air inside the storage box 2, thereby ensuring the temperature stability and internal safety inside the storage box 2. In order to further ensure the temperature stability inside the storage box 2, a number of plastic sheets can be provided at the through openings of the storage groove 9 and the taking groove 8.

[0050] When some existing storage devices are in use, their closed doors need to be opened manually. During this process, it is easy for other stored test tubes to be exposed to the outside air. Therefore, during this process, the operator's operation needs to be extremely careful to avoid operational errors, which may lead to inconvenience in storage. Therefore, a first lifting component and a second lifting component for lifting the placement component are respectively provided at the bottom of the storage slot 9 and the picking slot 8. After the test tube is placed in the placement component, it is sent into the storage box 2 by the second lifting component, and when it needs to be taken out, it is sent out of the storage box 2 by the first lifting component, completing the storage and picking operations of the placement component (i.e., the test tube).

[0051] Specifically, the first lifting component includes a first electric control lifting frame. One end of the first electric control lifting frame is arranged at the bottom of the picking slot 8, and the other end of the first electric control lifting frame is fixedly connected with a first lifting platform 4. When the placement component to be picked is placed on the first lifting platform 4, in order to further improve the automation degree of the whole process, a position sensor (the model can be preferably E3Z-T61) electrically connected to the control panel can be arranged on the surface of the first lifting platform 4. After the position sensor is triggered (i.e., after the placement component is placed on the first lifting platform 4), the control panel controls the first electric control lifting frame to expand and contract, so that the placement component is sent out of the storage box 2, and then the operator can open the first isolation plate 3 of the picking slot 8 and take out the placement component. The second lifting component includes a second electric control lifting frame. One end of the second electric control lifting frame is arranged at the bottom of the storage slot 9, and the other end of the second electric control lifting frame is fixedly connected with a second lifting platform 5. During storage, the second electric control lifting frame is in a contracted state. When the placement component to be stored is placed on the surface of the second lifting platform 5, similarly, a corresponding position sensor (the model can be preferably E3Z-T61) can also be arranged on its surface to help the control panel judge whether the placement component is in place. Then the second electric control lifting frame moves upward, so that the placement component on the second lifting platform 5 is sent into the storage box 2, and then it is clamped and placed at a preset position by the clamping component. Both the first electric control lifting frame and the second electric control lifting frame are electrically connected to the control panel. And both the first electric control lifting frame and the second electric control lifting frame adopt a double-layer X-shaped articulated folding structure, reducing the possibility of shaking and tilting, which helps to ensure the safety of the placement component during lifting and avoid damage caused by shaking. The first electric control lifting frame and the second electric control lifting frame can be folded up after the lifting is completed to save storage space.

[0052] Specifically, since it is necessary to store and retrieve the placement components, and the storage slots 9 and the retrieval slots 8 are symmetrically located on both sides of the storage box 2, that is, the clamping component needs to move the placement components within a certain range inside the storage box 2 to ensure the normal operation of placing the placement components on the first lifting platform 4 and retrieving them on the second lifting platform 5. Therefore, the clamping component includes a moving guide rail 11 provided on the inner top wall of the storage box 2. The moving guide rail 11 is slidably fitted with a moving seat electrically connected to the control panel. The bottom end of the moving seat is fixedly connected to a three-axis robotic arm 10 signal-connected to the control panel. Among them, the model of the moving seat can preferably be a servo motor-driven rotating seat, so as to increase the movement range of the three-axis robotic arm 10 inside the storage box 2 by using the cooperation of the moving guide rail 11 and the moving block.

[0053] Regarding the storage position of the placement components inside the storage box 2, a heat preservation box 12 is installed inside the storage box 2. A number of heat preservation cavities 13 are linearly arranged in an array from top to bottom on one side of the heat preservation box 12. Electrically controlled telescopic plates 14 that are slidably fitted inside the heat preservation cavities 13 are provided in the heat preservation cavities 13. At the same time, the preservation of general tumor samples requires low temperature, so a cryogenic machine 15 communicating with the inner cavity of the storage box 2 is built in the bottom of the storage box 2, and the cryogenic machine 15 is electrically connected to the control panel.

[0054] In the direction of intelligent control, the control panel includes a control unit, a detection unit, and an interaction unit;

[0055] The detection unit is used to detect the internal temperature of the storage box 2; it is also used to obtain the image information of the placement components placed on each electrically controlled telescopic plate 14, generate the coordinate information of each placement component, label each placement component, and output the corresponding comprehensive information;

[0056] The interaction unit is used to display the three-dimensional image of the internal components of the storage box 2, and based on the comprehensive information output by the detection unit, display the internal temperature of the storage box 2 in the three-dimensional image, and display the three-dimensional models of the placement components on each layer of the electrically controlled telescopic plate 14. The three-dimensional models of each placement component are marked with the corresponding saved time and model label; it is also used for the operator to select the placement component to be retrieved, and take out the selected placement component through the clamping component; it is also used to place the placement component to be stored at a certain position on a certain electrically controlled telescopic plate 14 selected by the operator through the clamping component.

[0057] At the same time, temperature is crucial for the preservation of tumor samples. Therefore, the control panel also includes a temperature control unit, which is used to adjust the output power of the cryogenic machine 15 based on the preset preservation temperature, which helps to ensure that the samples are always stored at the optimal preservation temperature and avoid sample deterioration or inactivation caused by temperature changes.

[0058] Embodiment 2:

[0059] The difference from Embodiment 1 is that, asFigure 1 , Figure 4 , Figure 5 and Figure 6 As shown in Figure 1 , Figure 4 , Figure 5 and Figure 6 , the placement components all include a placement block 7 and a controller arranged inside the placement block 7. Grooves are formed at the top of the placement block 7, and placement slots 19 for storing test tubes are formed at the center positions of the bottoms of the grooves. Before storage, take out the placement block 7 from the toolbox 1, and place the test tube containing the tumor sample to be stored into the placement slot 19. Airbag rings 18 close to the bottom of the groove are fixedly connected to the inner walls of the placement slots 19. Telescopic cavities corresponding to the placement slots 19 are arranged at the inner bottoms of the placement blocks 7. Pistons 26 that are slidably matched with the inner walls of the telescopic cavities are arranged in the telescopic cavities. Connecting rods 25 that are slidably connected to the placement blocks 7 are fixedly connected to the tops of the pistons 26. The tops of the connecting rods 25 all extend into the placement slots 19 and are fixedly connected to hemispherical pressure-receiving seats 20. A number of first springs 24 are fixedly connected to the outer surfaces of the pressure-receiving seats 20, and the other ends of the first springs 24 are all fixedly connected to the inner walls of the placement slots 19. Air vent channels 28 communicating with the airbag rings 18 are formed at the bottoms of the telescopic cavities. During the process of placing the test tube, the bottom of the test tube will contact and downwardly press the pressure-receiving seat 20, so that the connecting rod 25 pushes the piston 26 to squeeze the air in the telescopic cavity, and this part of the air is transported to the airbag ring 18 through the air vent channel 28 to make it expand, thereby fixing the test tube. During this process, the first springs 24 are synchronously compressed. At the same time, in order to ensure the reliability of the reset of the first springs 24, magnetic adsorption layers 27 are adhesively bonded to the bottoms of the pistons 26, and first electromagnets 29 corresponding to the magnetic adsorption layers 27 are adhesively bonded to the inner bottom walls of the telescopic cavities. The first electromagnets 29 are all electrically connected to the controller. First buttons 16 for controlling the opening and closing of the first electromagnets 29 are arranged at the tops of the placement blocks 7. The first electromagnets 29 are in the energized state in the initial state, and when the test tube is placed in place, the sum of the suction force of the first electromagnets 29 on the magnetic adsorption layers 27 and the gravity of the test tube (containing the tumor sample inside) is greater than the resultant force of the first springs 24, thereby ensuring the stability of the test tube after being placed in place; if it is necessary to take out the test tube from the placement block 7, only need to press the first button 16 to cut off the power supply of the first electromagnet 29. At this time, the resultant force of the first springs 24 is greater than the gravity of the test tube, so that the first springs 24 are reset, the pressure-receiving seat 20 moves upward, and at the same time, the gas in the airbag ring 18 is sucked into the telescopic cavity. At this time, the airbag ring 18 deflates, reducing the fixing effect on the test tube, so that the test tube is jacked up by the pressure-receiving seat 20 for a certain distance, facilitating the operator to take it. At the same time, it is also particularly important to ensure that the tumor sample is not interfered by other factors before detection. Therefore, a protective shell is hinged in the groove. The protective shell can closely fit the groove in the closed state, effectively preventing pollutants such as dust and stains from entering the inside of the groove and keeping the test tube clean and hygienic.

[0060] Example 3:

[0061] The difference from Example 2 is that, as shown in and

[0061] , Figure 1 ,Figure 2 , Figure 4 and Figure 5 As shown in Figure 2 , Figure 4 and Figure 5 , when detecting the placement block 7 placed on the electric control telescopic plate 14, in order to make better use of the internal space of the incubator 12 and facilitate the grasping and placement of the three-axis robotic arm 10, a plurality of docking components for docking adjacent placement blocks 7 are provided on the side surfaces of the placement block 7 close to the bottom. The adjacent placement blocks 7 are docked by using the docking components, so that these placement blocks 7 are neatly arranged on the corresponding electric control telescopic plate 14. At the same time, when grasping a certain placement block 7, the influence on other placement blocks 7 can be reduced. Specifically, the docking components each include a docking groove opened on the surface of the placement block 7. Inside the docking groove, a second electromagnet 21, a magnetic attraction plate 22 and a plurality of second springs 23 are respectively arranged from left to right (as shown in Figure 5 Figure 5 ). The second electromagnets 21 are fixedly connected to the inner wall of the docking groove, the magnetic attraction plates 22 are slidably connected to the inner wall of the docking groove, one ends of the second springs 23 are bonded to the magnetic attraction plates 22, and the other ends of the second springs 23 are bonded to the inner wall of the docking groove. The second electromagnets 21 are electrically connected to the controller. A plurality of second buttons 17 corresponding to the second electromagnets 21 are provided on the side surfaces of the placement block 7 close to its top end. When the second button 17 is pressed, the second electromagnet 21 is powered off. On the contrary, the second electromagnet 21 is powered on.

[0062] When the placement block 7 is clamped by the three-axis robotic arm 10, the second buttons 17 on its surface are all pressed by the three-axis robotic arm 10. At this time, the second electromagnet 21 is powered off, so that other placement blocks 7 will not be affected before the placement is completed. After the placement block 7 is placed in the designated area of the electric control telescopic plate 14 by the three-axis robotic arm 10, the three-axis robotic arm 10 falls off. At this time, the second button 17 is reset and the second electromagnet 21 is powered on. At this time, it can be docked with other already stored placement blocks 7. When the second electromagnet 21 is powered on, it will attract the magnetic attraction plate 22 and stretch the second spring 23 for energy storage. When the placement block 7 is taken, the three-axis robotic arm 10 presses the second button 17 again, the second electromagnet 21 is powered off, and the second spring 23 is reset, pulling the magnetic attraction plate 22 to move. At the same time, a plurality of through holes are opened on the surface of the magnetic attraction plate 22, so that the magnetic attraction plate 22 squeezes the air in the right cavity of the docking groove, and makes it flow quickly through the through holes to achieve the effect of cleaning the dust inside the docking groove.

[0063] Embodiment 4:

[0064] The difference from Embodiment 3 is that the specific operation steps of the sample storage device for tumor detection are as follows:

[0065] Step 1: Take out the placement block 7 placed in the toolbox 1, open the protective shell, place the test tube containing the tumor sample to be preserved in the placement groove 19. After completion of fixation, close the protective shell. When medical staff take samples, they often need to temporarily organize multiple test tubes on the experimental table (such as labeling and preliminary classification). The placement block 7 forms a "test tube protection chamber" through the airbag ring 18 and the spring buffer structure. Its hinged protective shell design allows for quick opening and closing, providing an ergonomic operation interface for medical staff. The sliding placement plate 6 in the toolbox 1 can store multiple empty placement blocks 7 simultaneously, forming a "test tube loading workstation" for immediate use. This design transforms discrete test tube samples into traceable standardized storage units.

[0066] Step 2: Place the placement block 7 with the test tube on the second lifting platform 5, and then the second electric control lifting frame lifts the second lifting platform 5 to send the placement block 7 with the test tube into the storage box 2. Then, the three-axis robotic arm 10 grabs the placement block 7, lifts it to the placement origin, and pushes out the corresponding electric control telescopic plate 14 to place the placement block 7 in the designated area. Then, the electric control telescopic plate 14 retracts. When storing the placement block 7, if there is no intervention of human instructions, the three-axis robotic arm 10 automatically places the grabbed placement block 7 next to the previously stored placement block 7, and then performs position fine-tuning to make the docking grooves on the opposite sides of the two correspond, so that the two are docked, thereby improving the utilization efficiency of the internal space of the incubator 12 and also reducing the impact on these placement blocks 7 that need to be continuously stored during subsequent storage and retrieval.

[0067] Step 3: When taking, select the placement block 7 to be taken through the control panel. The three-axis robotic arm 10 clamps the placement block 7 and moves to directly above the first lifting platform 4, places the placement block 7 on the first lifting platform 4. Then, the first lifting platform 4 descends. After reaching the position, take out the placement block 7. Open the protective shell and press the first button 16 to disconnect the first electromagnet 29. The first spring 24 resets, and the test tube is lifted to a corresponding height from the placement groove 19, facilitating the operator to take it.

[0068] Obviously, the above embodiments are merely examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
