Description

Technical Field

[0001] This invention relates to the field of medical auxiliary device technology, specifically to a preservation device for breast and thyroid surgical biopsy samples. Background Technology

[0002] In the clinical diagnosis and treatment and medical research of thyroid and breast surgery, the collection, preservation, and transportation of live samples are crucial steps in ensuring the accuracy of pathological diagnosis, molecular testing, and prognostic analysis. Thyroid and breast live samples typically contain bioactive substances such as tissue fragments, cell suspensions, or aspirates; their quality and integrity directly affect subsequent pathological evaluation and the development of personalized treatment plans. Currently, plastic or glass sample tubes are widely used in clinical practice as the primary storage and transportation containers for samples. While these containers are inexpensive and easy to manufacture, they present significant safety deficiencies in actual operation.

[0003] Specifically, taking a medical sample tube called "Kasico" as an example, it is mainly made of plastic. Although the plastic sample tube has advantages such as high chemical stability and good light transmittance, its material is relatively brittle. During the transportation of samples after collection, it is usually held by personnel or placed in a test tube rack. If the sample tube is dropped or subjected to external impact, it is very easy to break due to external impact. Once the sample tube is broken, the internal live sample will be directly exposed to the external environment, which not only leads to sample loss and contamination, but also wastes precious clinical samples. Especially for collection methods with limited sample volume, such as puncture biopsy, sample loss may directly affect the reliability of diagnostic results, and may even require secondary sampling of patients, increasing their physiological pain and medical burden. In addition, the bioactive components such as pathogenic microorganisms and tumor cells contained in the sample may be transmitted through leakage, posing a potential infection risk to medical staff, laboratory operators and the environment.

[0004] In conclusion, it is necessary to propose a preservation device for breast and thyroid surgical biopsy samples to solve the above problems. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a preservation device for breast and thyroid surgical biopsy samples. This device features adaptive shock protection and aims to achieve end-to-end protection through a mechanical linkage structure, encompassing "abnormal posture - automatic clamping - stable reset," thereby enhancing the stability and safety of the sample tube during transport and meeting the preservation requirements for high integrity and low contamination risk of breast and thyroid surgical clinical samples.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: a preservation device for breast and thyroid surgical biopsy samples, comprising a protective shell, a plurality of L-shaped support plates provided on the inner wall of the protective shell, each L-shaped support plate having a through hole on its short side, a support column being slidably fitted in each through hole, a push plate being fixedly connected to one end of each support column near the inner wall of the protective shell, a spring sleeved on one side of each push plate near the support column, the other end of each spring being fixedly connected to the L-shaped support plate; and an arc-shaped clamping block being provided at the other end of each support column. The inner wall of the protective shell is provided with a number of rotating shafts corresponding to the number of push blocks. Each rotating shaft is rotatably connected to a pushing component located below the long side of the L-shaped support plate for pushing the push plate away from the protective shell. The push plates are all located in the movement trajectory of the pushing component. The bottom wall inside the protective shell is provided with a base, and the top of the base is provided with a storage slot.

[0007] The technical principle of the above solution is as follows: The preservation device of the present invention forms an integral protective structure through a protective shell, and the L-shaped support plate provided on its inner wall provides a mounting base for each component. The through hole on the short side of the L-shaped support plate forms a sliding fit with the support column, allowing the support column to move axially along the through hole; a push plate is fixedly connected to one end of the support column near the inner wall of the protective shell, and the push plate and the L-shaped support plate are elastically connected by a spring sleeved on the outside of the support column, while the arc-shaped clamp at the other end of the support column directly acts on the outer wall of the sample tube. The rotating shaft of the inner wall of the protective shell forms a rotational connection with the pushing assembly, and the movement trajectory of the pushing assembly covers the position of the push plate. When the protective shell tilts or falls, under the action of gravity, the pushing assembly rotates around the axis. During the rotation, the pushing assembly contacts the push plate and applies a pushing force, causing the push plate to move along the support column axially towards the L-shaped support plate, while compressing the spring to generate elastic potential energy; at this time, the support column slides towards the central axis of the protective shell under the drive of the push plate, and the arc-shaped clamp moves synchronously with the support column and gradually fits against the outer wall of the sample tube placed in the base placement groove, realizing the elastic clamping and fixing of the sample tube. The placement groove at the top of the base provides positioning support for the bottom of the sample tube. Together with the radial clamping of the arc-shaped clamping block, they restrict the displacement of the sample tube within the protective shell, preventing direct impact from shaking or external force collisions during transport, which could lead to sample tube breakage and sample leakage.

[0008] The above approach has the following beneficial effects: 1. This solution, through the elastic clamping structure of the arc-shaped clamping block and the spring, can form a uniform circumferential clamping force on the sample tube, effectively limiting the radial and axial displacement of the sample tube within the protective shell, avoiding rigid collisions between the sample tube and the inner wall of the protective shell or other components, and fundamentally reducing the risk of sample tube breakage due to external impact.

[0009] 2. In this design, the spring provides a buffering effect during the clamping process. When the protective shell is subjected to external impact, the spring can absorb some of the impact energy through its own deformation, reducing the impact force transmitted to the sample tube. At the same time, the arc-shaped contact surface of the arc-shaped clamp can disperse the clamping stress, preventing the sample tube from being damaged due to excessive local stress.

[0010] 3. This solution utilizes a gravity-based linkage design, employing gravity as the natural power source to trigger the clamping action, achieving automated response without the need for additional power. This gravity-centric triggering mechanism can respond rapidly in the instant of abnormal protective shell posture, ensuring that the sample tube is fixed by the elastic support structure before being subjected to external impact, thus forming dynamic support and protection for the sample tube.

[0011] Furthermore, each of the pushing components includes a support rod located below the long side of the L-shaped support plate. Each support rod is fixedly connected to a rotating ring, which is rotatably connected to a corresponding rotating shaft. Each support rod has a cylinder at one end near the long side of the L-shaped support plate and a pendulum ball at the other end. The push plate is located in the motion trajectory of the corresponding cylinder.

[0012] Beneficial effects: Through the rotating connection between the rotating ring and the rotating shaft, and the distribution design of the cylinders and pendulum balls at both ends of the support rod, the pendulum balls can drive the support rod to rotate around the rotating ring by gravity or inertia when the protective shell is shaken by external force or changes in posture. This, in turn, drives the cylinder to precisely push the push plate to trigger the clamping action. This structure can achieve dynamic responsive clamping of the sample tube without an additional power source, improving the timeliness and automation of the device in dealing with sudden impacts during transportation, and ensuring that the sample tube is always in a stable clamping state.

[0013] Furthermore, the protective shell is rectangular.

[0014] Beneficial effects: By designing the protective shell in a cuboid shape, utilizing the geometric properties of its planar outer wall and right-angled edges, the shell can form stable support through its planar structure and contact surface when dropped or tipped over, ensuring that the shell can quickly stop its displacement after a fall. This design reduces the probability of secondary collisions caused by rolling, avoids repeated impacts between the sample tube and the inner wall of the shell during continuous shaking, thereby reducing the risk of the sample tube breaking due to multiple collisions and improving the stability and safety of sample transportation.

[0015] Furthermore, a clamping pad is provided inside the storage slot.

[0016] Beneficial effects: The clamping pad can fill the gap between the bottom of the sample tube and the inner wall of the storage groove. Through its own elastic deformation, it increases the friction and contact area of ​​the bottom of the sample tube, preventing the sample tube from sliding radially or axially in the storage groove. At the same time, the clamping pad can absorb the vertical impact on the bottom of the sample tube, preventing the bottom from being damaged due to direct contact between the rigid base and the sample tube, and further strengthening the protection of the bottom of the sample tube.

[0017] Furthermore, a cover is hinged to the top of the protective shell.

[0018] Beneficial effects: The hinged structure allows the cover to rotate flexibly around the top of the protective shell, achieving a sealed coverage of the internal space of the protective shell, effectively isolating external dust, moisture or contaminants, and avoiding sample contamination; at the same time, when the cover is closed, it can form a secondary limit on the internal pushing components or sample tubes, ensuring that the clamping structure works continuously and stably during transportation.

[0019] Furthermore, a stop post is provided at the bottom of the shell cover.

[0020] Beneficial effects: When the shell is closed, the abutment can contact the top of the sample tube and apply axial pressure, forming an axial limit with the bottom support of the base placement groove, preventing the sample tube from moving up and down due to bumps or flipping; the abutment setting restricts the sample tube in both the axial and radial directions, forming a "three-dimensional fixation" effect, further reducing the probability of the sample tube colliding with the inner wall of the protective shell.

[0021] Furthermore, a buffer layer is provided on the side of the arc-shaped clamps away from the support.

[0022] Beneficial effects: The buffer layer is made of elastic material and is in direct contact with the outer wall of the sample tube. It can disperse the clamping force applied by the arc-shaped clamping block through its own deformation, avoiding excessive local stress on the sample tube and causing it to break. At the same time, the micro-texture on the surface of the buffer layer can increase the friction with the sample tube, prevent the sample tube from rotating circumferentially under clamping conditions, and improve clamping stability.

[0023] Furthermore, the length of the support rod above the swivel is shorter than the length of the section below the swivel.

[0024] Beneficial effects: By leveraging the principle, the longer support rod section below the rotating ring increases the gravitational lever arm of the pendulum. When the protective shell shakes slightly, the pendulum can generate a large torque to drive the support rod to rotate, significantly improving the triggering sensitivity of the push component. This design ensures that the device can quickly respond and clamp the sample tube when subjected to slight external force, shortening the impact response time and enhancing the timeliness of protection.

[0025] Furthermore, identification markings are provided on the outer wall of the protective shell.

[0026] Beneficial effects: Identification labels can intuitively display the basic information of samples, making it easy for operators to quickly identify and distinguish different samples, avoiding sample confusion or mis-taking; at the same time, the standardized design of the labels helps the information management and traceability of samples, improving the efficiency of laboratory operations.

[0027] Furthermore, a flap is provided on the top of the shell cover.

[0028] Beneficial effects: The lever provides a convenient point of force for the cover, allowing users to easily open or close the cover by levering it. This effectively prevents slippage, especially when wearing gloves or with wet hands, improving the convenience and safety of operation and increasing retrieval efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] The following detailed description illustrates the specific implementation method: Example 1:

[0035] A preservation device for breast and thyroid surgical biopsy samples, see attached document. Figure 1 and attached Figure 2 As can be seen, the protective shell 1 has an identification mark 18 affixed to its outer wall to facilitate quick differentiation of different sample information and improve management and traceability efficiency; a shell cover 15 is hinged to the top of the protective shell 1, and a stop post 16 is affixed to the bottom of the shell cover 15. The stop post 16 can axially limit the top of the sample tube when the shell cover 15 is closed. A flap 19 is affixed to the top of the shell cover 15 to provide a convenient force application point for opening and closing the shell cover 15; several L-shaped support plates 2 are welded to the inner wall of the protective shell 1. Each of the short sides of the L-shaped support plates 2 has a through hole, and a support post 3 is slidably fitted into each through hole. The guide movement of the support column 3 is achieved through the sliding fit between the through hole and the support column 3. The end of the support column 3 near the inner wall of the protective shell 1 is attached with a push plate 4. The side of the push plate 4 near the support column 3 is welded with a spring 5 sleeved on the outside of the support column 3. The other end of the spring 5 is welded to the L-shaped support plate 2. The elastic deformation of the spring 5 can realize the automatic reset of the support column 3. The other end of the support column 3 is attached with an arc-shaped clamping block 6. The side of the arc-shaped clamping block 6 away from the support column 3 is attached with a buffer layer 17 to disperse the clamping stress through elastic contact and avoid the outer wall of the sample tube from directly contacting the hard clamping block. Combined with appendix Figure 1 and attached Figure 4It is known that the inner wall of the protective shell 1 is welded with a number of rotating shafts 7 corresponding to the number of push plates 4. Each rotating shaft 7 is rotatably connected to a pushing component located below the long side of the L-shaped support plate 2, which is used to push the push plate 4 away from the protective shell 1. Each pushing component includes a support rod 10, and a rotating ring 11 is welded to each support rod 10. The rotating ring 11 is rotatably connected to the corresponding rotating shaft 7. The flexible rotation of the support rod 10 is achieved through the cooperation of the rotating ring 11 and the rotating shaft 7. A cylinder 12 is welded to one end of the support rod 10 near the long side of the L-shaped support plate 2, and a pendulum ball 13 is welded to the other end of the support rod 10. The gravity of the pendulum ball 13 can drive the support rod 10 to rotate around the rotating shaft 7. The push plates 4 are respectively located in the motion trajectory of the corresponding cylinder 12, ensuring that the rotation of the cylinder 12 can accurately trigger the displacement of the push plate 4. In this design, the length of the support rod 10 above the rotating ring 11 is shorter than the length of the portion below the rotating ring 11. By designing the support rod 10 as an asymmetrical structure with a shorter upper section and a longer lower section, the lever principle is used to increase the gravitational lever arm of the pendulum ball 13 to improve trigger sensitivity. When the protective shell 1 tilts or shakes, the torque generated by the pendulum ball 13 under gravity can drive the support rod 10 to rotate rapidly, causing the cylinder 12 to push the push plate 4 along an arc trajectory to compress the spring 5, thereby driving the arc-shaped clamping block 6 to move towards the sample tube and then contact the sample tube to complete the clamping of the sample tube. The inner bottom wall of the protective shell 1 is provided with a base 8, and the top of the base 8 is provided with a placement groove 9. The placement groove 9 forms a positioning support for the bottom of the sample tube, which, together with the radial clamping of the arc-shaped clamping block 6, constitutes a three-dimensional fixing structure for the sample tube.

[0036] The specific implementation process is as follows: When the breast and thyroid surgical biopsy sample is cut from the patient's body, this device is used to temporarily preserve the breast and thyroid surgical biopsy sample. Medical staff will first open the shell cover 15 by flipping the cover 19 and place the sample tube in the storage slot 9 at the top of the base 8. The storage slot 9 and the clamping pad 14 will initially fix the bottom of the sample tube. Then, the shell cover 15 will be closed, and the abutment 16 at the bottom of the shell cover 15 will fix the top of the sample tube, thereby completing the axial fixation of the sample tube. When the device is in a normal static state, the pendulum 13 hangs naturally under the action of gravity, the support rod 10 remains vertical, the cylinder 12 does not contact the push plate 4, the spring 5 is in a naturally extended state, and the arc-shaped clamp 6 does not contact the sample tube. When a breast or thyroid biopsy sample needs to be sent to the laboratory for testing, and when the device is accidentally tilted or dropped during transportation, the change in the posture of the protective shell 1 causes the pendulum 13 to deviate from its equilibrium position due to inertia or gravity, driving the support rod 10 to rotate rapidly around the rotating ring 11. Since the lower part of the support rod 10 is longer than the upper part, the gravitational lever arm of the pendulum 13 is significantly increased. Even a small change in posture can generate enough torque to drive the cylinder 12 to swing upward along the arc trajectory, thereby pushing the push plate 4 on the side of the protective shell 1 in the tilt direction to move towards the L-shaped support plate 2. During the movement of the push plate 4, the spring 5 is compressed, storing the elastic potential energy inside the spring 5. At the same time, the support column 3 slides along the through hole axis towards the sample tube, causing the arc-shaped clamp 6 to gradually approach the outer wall of the sample tube. The buffer layer 17 first contacts the sample tube and undergoes elastic deformation to absorb part of the kinetic energy. At this time, the arc-shaped clamp 6 contacts the outer wall of the sample tube, lifting the sample tube and preventing the sample tube from tilting towards the protective shell 1. This completes the side wall support of the sample tube. The spring 5 can also absorb part of the kinetic energy at this time, further reducing the impact force of external force on the sample tube when tilting or falling. At this time, the sample tube is three-dimensionally fixed under the combined action of the bottom support of the placement groove 9, the radial support of the arc-shaped clamp 6, and the top limit of the support column 16, effectively offsetting the shaking caused by external impact.

[0037] Once the device returns to a stable state, the pendulum 13 returns to its initial downward position under the influence of gravity. The support rod 10 rotates in the opposite direction, causing the cylinder 12 to disengage from the push plate 4. The spring 5 releases its stored elastic potential energy, pushing the push plate 4 and the support column 3 back to their original positions. The arc-shaped clamp 6 then disengages from the sample tube. The operator can open the shell cover 15 through the flap 19 to directly remove the sample tube. In this process, gravity is the sole power source, achieving adaptive lifting without the need for electricity or manual intervention. The lever structure design of the support rod 10 significantly improves the responsiveness to changes in posture. The elastic cooperation between the spring 5 and the arc-shaped clamp 6 avoids damage to the sample tube caused by rigid clamping. The overall structure achieves fully automated protection of the entire process of "abnormal posture - automatic lifting - stable reset" through mechanical linkage, preventing the sample tube from breaking due to accidental drops, resulting in sample loss and biological pollution to the environment. It is especially suitable for the high stability requirements of transporting breast and thyroid biopsy samples between operating rooms and laboratories.

[0038] The following experiments are designed based on the above embodiments to highlight the superiority of the device provided in the above embodiments for sample preservation.

[0039] Experimental Objective By simulating external impacts (such as free fall and tilting collisions) in clinical transport scenarios, the integrity of sample tubes and sample retention rate under different protection methods are compared to verify the superiority of the anti-breakage protection of the device based on gravity-triggered adaptive clamping mechanism.

[0040] Table 1 Experimental Materials and Grouping Grouping Protection methods Sample tube specifications Sample Simulation Control group 1 (no protection) The sample tubes are directly exposed without external cushioning or fixing structures. CASECCO 10mL Plastic Sample Tube Deionized water-glycerol mixture (density 1.05 g / cm³) Control group (traditional protection) Commonly used clinical foam buffer boxes (lined with 2cm thick EPE pearl cotton, with one sample tube fixed in each compartment). Same as above Same as above Experimental Group (Inventive Device Group) The preservation device in this embodiment includes a gravity-triggered pushing component, an arc-shaped clamping block for elastic clamping, and a three-dimensional fixing structure. Same as above Same as above III. Experimental Methods and Test Indicators Free fall impact test: Fall height: 1.0m (simulating a fall from waist height), 1.5m (simulating a transfer vehicle slipping). Impact surface: Hospital anti-slip ceramic tile (hardness 70 Shore D); Each group contains 50 sample tubes, and the test is repeated 10 times at each height. The breakage rate (including complete breakage and cracks) and the sample leakage rate (the proportion of leakage to the initial amount) are recorded.

[0041] Tilt-down collision test: Tilt angle: 30° (slight tilt), 60° (moderate tilt), 90° (complete tilt); Impact force: 0.5 N·s (simulating the inertia of the transport vehicle during emergency braking); Each group consists of 50 sample tubes. The test is repeated 10 times at each angle. The number of tube wall damages (including scratches and cracks) and the maximum displacement (axial / radial displacement of the sample tube at the moment of impact) are recorded.

[0042] Composite scenario testing: Cyclic conditions: 1.0m drop + 60° tilt impact, repeated 3 times (simulating multiple superimposed bumps); Test metrics: final integrity (whether it remains sealed) and sample retention rate (the proportion of the retained sample to the initial sample).

[0043] Table 2 Experimental Results and Comparative Analysis Test Project Control group 1 (no protection group) Control group 2 (traditional protection group) Experimental group (device group of this invention) 1.0m height breakage rate >30% (mostly completely broken, resulting in sample leakage) 15%-25% (mainly bottom cracks, leakage rate 30%-40%) <9% (only 1 case of minor scratches, no cracks or leaks) 1.5m height breakage rate >40% (Completely broken, sample leakage rate 80%) 25%-33% (30% completely broken, leakage rate >65%) <2% (No breakage observed, only 2 cases of slight deformation of the buffer layer) Number of injuries at a 30° tilt 3-5 times / piece (dense scratches on the pipe wall, 60% of which will develop cracks) 1-2 times / piece (insufficient pearl cotton cushioning, micro-cracks appear in 20%-30% of cases). 0 times / piece (no relative displacement after the arc-shaped clamp is tightened, and no damage to the pipe wall) Maximum displacement at 90° tilt >15mm (sample tube directly collides with impact surface) 8-12mm (the compression of pearl cotton is limited, and axial sway is obvious). <4mm (three-dimensional fixed displacement restriction, buffer layer absorbs impact energy) Final sample retention rate <28% (sample almost completely leaked) 30%-40% (some sample tubes broke due to repeated impacts) >90% (sample tubes are intact, well-sealed, and the retention rate is close to the initial amount) V. Experimental Conclusions Based on the above experimental results, it can be seen that the device effectively reduces the risk of sample tube breakage and sample leakage through a full-process protection mechanism of "trigger response - clamping fixation - impact absorption". When the device encounters extreme scenarios such as free fall or tilting collision, the elastic clamping of the arc-shaped clamp can absorb the impact energy, and the deformation of the buffer layer can offset the direct action of external force on the tube wall. Combined with the rigid frame of the protective shell, it can avoid direct contact between the sample tube and the external hard surface. At the same time, the sample tube does not have obvious shaking or collision under three-dimensional fixation, and can maintain the seal integrity, solving the problem of sample tube easily breaking due to impact and sample leakage in traditional unprotected or simple buffering methods.

[0044] Example 2:

[0045] As attached Figure 1 and attached Figure 2 As shown, the difference from Embodiment 1 is that the protective shell 1 is a cuboid.

[0046] The specific implementation process is as follows: By designing the protective shell 1 as a cuboid shape, and utilizing the geometric characteristics of its planar outer wall, the protective shell 1 can form a stable support with the contact surface through its planar structure when it falls, ensuring that the protective shell 1 can quickly stop rolling after falling. This design reduces the probability of secondary collisions caused by the rolling of the protective shell 1, avoids repeated impacts between the sample tube and the inner wall of the shell during continuous shaking, thereby reducing the risk of the sample tube breaking due to multiple collisions and improving the stability and safety of the sample transportation process.

[0047] Example 3:

[0048] The difference from Example 2 is as follows: Figure 1 As shown, a clamping pad 14 is provided inside the storage slot 9.

[0049] The specific implementation process is as follows: The clamping pad 14 can fill the gap between the bottom of the sample tube and the inner wall of the placement groove 9. Through its own elastic deformation, it increases the friction and contact area of ​​the bottom of the sample tube, preventing the sample tube from sliding radially or moving axially in the placement groove 9. At the same time, the clamping pad 14 can absorb the vertical impact on the bottom of the sample tube, preventing the bottom from being damaged due to direct contact between the rigid base 8 and the sample tube, and further strengthening the protection of the bottom of the sample tube.

[0050] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
