Description

Technical Field

[0001] This invention belongs to the field of sample collection technology, specifically relating to a bone sample collection device for osteoporosis. Background Technology

[0002] Osteoporosis is a common metabolic bone disease characterized by decreased bone mass and deterioration of bone structure, leading to fragile bones and susceptibility to fractures. With the increasing aging of the population, the incidence of osteoporosis is rising year by year, becoming a significant health problem among the elderly population worldwide. Bone sample collection and analysis play a crucial role in the research and diagnosis of osteoporosis. By collecting and analyzing bone tissue samples, researchers can understand the microstructure, mineralization level, and changes in bone, thereby exploring the mechanisms of osteoporosis, diagnostic methods, and treatments. Analyzing the components and changes in bone tissue using techniques such as cytology and molecular biology can help scientists gain a deeper understanding of the root causes of osteoporosis, thus providing a theoretical basis for developing new drugs or treatments.

[0003] Osteoporotic bone samples exhibit strong heterogeneity (such as differences in the density, size, and porosity of trabeculae). Existing sampling devices typically only acquire samples from limited regions, making it difficult to comprehensively reflect the diversity and heterogeneity of the entire skeleton. Due to significant differences in different parts of bone tissue, sampling results may not fully represent the microstructure of the entire skeleton, thus increasing the error in analytical results. Furthermore, different patients have different osteoporosis conditions, and their bone microstructure changes also vary. Existing sampling devices are often standardized and lack personalized customization capabilities for specific cases. This makes the sampling devices less adaptable when dealing with osteoporosis samples from different patients or with different pathological states, potentially leading to sampling bias or errors and increasing uncertainty. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an osteoporosis bone sample collection device.

[0005] The technical solution adopted to solve the above-mentioned technical problems is: an osteoporosis bone sample collection device, including a sampling platform, a control panel installed on one side of the sampling platform, and two collection boxes placed at the bottom of the sampling platform. At the same time, a guide plate is welded to the center of the top surface of the sampling platform. The guide plate is U-shaped and its two ends are fixedly connected to the sampling platform. The top surface of the guide plate is connected to the collection box at the bottom of the sampling platform. Adjustable fixed rotation components are welded to both sides of the guide plate for clamping and fixing bone tissue samples of different locations and densities. A multi-directional rotation component is welded to the top of the adjustable fixed rotation components for drilling bone samples from multiple angles.

[0006] The above technical solution allows for flexible adjustment based on different locations, densities, and microstructures of bone samples. By adjusting the spacing of the clamping device, the depth and position of the sampling area can be precisely controlled. This enables targeted sampling of bone tissues of different locations and densities (such as cortical bone and spongy bone), thereby improving the representativeness and accuracy of the samples.

[0007] Furthermore, the adjustable fixed rotation assembly includes two support frames arranged in a mirror symmetrical manner, with the two sides of the guide plate located inside the support frames and welded to them. At the same time, a fixed frame is fixedly connected to the bottom of the support frame. The fixed frame is fixedly connected to the center line of the top surface of the sampling platform. The support frame is arranged in an L-shaped structure. An adjustment plate with an H-shaped structure is rotatably connected to one side of the support frame, and adjustment rods are fixedly connected to both sides of the top of the adjustment plate.

[0008] The above technical solution allows for customized adjustments based on the specific characteristics of bone samples, enabling the equipment to adapt to different types of bone tissue. This flexibility ensures the extraction of representative samples from bone tissues of different locations or properties, reducing errors caused by uneven sampling.

[0009] Furthermore, connecting blocks are slidably connected to both sides of the bottom of the adjusting plate, and a slider is rotatably connected between the two connecting blocks. At the same time, a fixing strip is slidably connected through the bottom of the slider. The fixing strip is fixedly connected to the fixing frame. The adjusting plate limits the connecting blocks laterally, and the fixing strip limits the slider longitudinally. An adjusting block is engaged between the two adjusting rods, and the adjusting rods are slidably connected to the adjusting blocks. The adjusting rods also allow the adjusting blocks to be moved laterally. A double threaded rod is threadedly connected through the two sliders. The two ends of the double threaded rod are rotatably connected to the inner wall of the fixing frame. The double threaded rod passes through the guide plate without intersecting. The middle of the double threaded rod is fixedly connected to the second synchronous belt assembly.

[0010] The above technical solution enables efficient sample positioning and multi-point sampling. It can extract multiple samples in a shorter time and efficiently sample bone samples from different directions and depths. This efficiency is particularly useful when a large number of samples are needed for microscopic analysis or statistical research, which can greatly improve work efficiency.

[0011] Furthermore, a drive rod is fixedly connected through the center of the adjusting block, and two limiting strips are welded to the outer wall of the end of the drive rod away from the adjusting block. A limiting plate is fixedly connected to the end of the drive rod away from the limiting strips. Several symmetrically distributed rubber blocks are fixedly connected to the side of the limiting plate away from the drive rod. A mounting base is slidably connected through the end of the drive rod away from the adjusting block, and the mounting base is fixedly installed on the support frame. Bearings are rotatably connected to both sides of the fixed frame, and the bearings are located inside the fixed frame. The drive rod and limiting strips are slidably connected through the bearings. Two synchronous pulleys inside the drive rod are rotatably connected to the fixed frame, and the two synchronous pulleys are located at the top and bottom of the fixed frame, respectively. The synchronous belt inside the drive rod passes through the fixed frame without intersecting. The double-threaded rod is fixedly connected through the synchronous pulley located at the top of the fixed frame inside the drive rod. A second motor is installed at the bottom of the fixed frame, and the output end of the second motor is rotatably connected through the fixed frame. The end of the second motor is fixedly connected to the synchronous pulley located at the bottom of the fixed frame inside the drive rod.

[0012] Furthermore, a synchronous belt assembly is slidably connected to the drive rod and the limiting strip on one side of the fixed frame. One synchronous pulley in the synchronous belt assembly is fixedly connected to the bearing, while another synchronous pulley in the synchronous belt assembly is rotatably connected to the inner wall of the fixed frame. The limiting strip longitudinally limits one synchronous pulley in the synchronous belt assembly, and the synchronous pulley in the synchronous belt assembly rotates under the action of the limiting strip. At the same time, a motor is installed on the outer wall of one side of the fixed frame. The output end of the motor is rotatably connected to the fixed frame, and the through end of the motor is fixedly connected to the other synchronous pulley in the synchronous belt assembly.

[0013] The above technical solution not only allows for adjustment of the clamping distance, but also enables sampling of bone samples from multiple angles through rotation. By rotating, the device can cover a wider sampling area, ensuring the diversity and comprehensiveness of the samples.

[0014] Furthermore, the multi-directional rotation assembly includes a first connecting frame welded and fixed to the fixed frame, and a cross rod is rotatably connected between the two ends of the first connecting frame away from the fixed frame. At the same time, a second connecting frame is rotatably connected to the other two ends of the cross rod. A lifting hydraulic rod is installed at the center of the bottom surface of the second connecting frame, and a frame is fixedly connected to the telescopic end of the lifting hydraulic rod. A servo motor is installed inside the frame, and the output end of the servo motor is rotatably connected through the frame. A drill rod is fixedly installed at the through end of the servo motor.

[0015] The above technical solution supports drilling from multiple angles, which allows operators to extract bone samples from different directions and depths as needed. Extracting samples from different directions helps to more comprehensively reflect the characteristics of bone tissue and ensures the comprehensiveness and representativeness of the sampling.

[0016] Furthermore, a first gear and a second gear are respectively fixedly connected to the adjacent ends of the cross rod, and a first rack is engaged with one side of the first gear. At the same time, the side of the first rack away from the first gear is slidably connected to the first connecting frame. The first connecting frame limits the first rack, and a longitudinal hydraulic rod is provided at the top of the first rack. The longitudinal hydraulic rod is fixedly installed to the first connecting frame, and the telescopic end of the longitudinal hydraulic rod is slidably connected to the first connecting frame. The through end of the longitudinal hydraulic rod is also fixedly connected to the first rack.

[0017] Furthermore, the second gear meshes with a second rack on one side, and the side of the second rack away from the second gear is slidably connected to the second connecting frame. At the same time, the second connecting frame limits the second rack. A transverse hydraulic rod is provided at the bottom of the second rack, and the transverse hydraulic rod is fixedly installed to the second connecting frame. The telescopic end of the transverse hydraulic rod is slidably connected to the second connecting frame, and the through end of the transverse hydraulic rod is fixedly connected to the second rack.

[0018] The above technical solutions can be used to obtain samples from different directions, better reflect the microstructural characteristics of bone tissue, and thus provide more accurate data for subsequent research.

[0019] The beneficial effects of this invention are as follows: (1) By adopting an adjustable fixed rotation component, the No. 2 motor drives the linkage mechanism of the double threaded rod, slider and adjustment plate, the device can quickly and accurately fix and rotate the bone sample to the designated position, making the sampling process more efficient and reducing the operation time. Especially when it is necessary to extract samples from multiple positions, the device can be quickly adjusted through the control panel, reducing manual intervention and improving the overall work efficiency. (2) The present invention enables the equipment to be flexibly adjusted in different directions by using a multi-directional rotating component and a combination of longitudinal and transverse hydraulic rods to adapt to the shape and size requirements of different bone samples. When sampling at multiple sampling points, the equipment can complete drilling at multiple angles at the same position without repeatedly adjusting the sample, which greatly improves the efficiency and accuracy of sampling. During the drilling process, the powder or debris of the bone sample can quickly slide down to the guide plate by gravity and finally be collected in the collection box at the bottom. This design ensures the effective collection of sample residues, avoids leakage or contamination of debris, facilitates subsequent analysis or experiments, and also keeps the operating environment clean. (3) This invention integrates multiple functions, including sampling, clamping, rotation, drilling, and powder collection, which avoids the complex operation of relying on multiple independent systems in traditional equipment, improves the overall work efficiency, and allows users to complete multiple complex tasks through simple operation, reducing the space occupied by the equipment and improving the overall work efficiency.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0023] like Figures 1-8This embodiment of an osteoporosis bone sample collection device includes a sampling platform 11. A control panel 12 is installed on one side of the sampling platform 11, and two collection boxes 13 are placed at the bottom of the sampling platform 11. A guide plate 14 is welded to the center of the top surface of the sampling platform 11. The guide plate 14 has a U-shaped structure, and its two ends are fixedly connected to the sampling platform 11. The top surface of the guide plate 14 is connected to the collection box 13 at the bottom of the sampling platform 11. Adjustable fixing and rotating components 2 are welded to both sides of the guide plate 14 for clamping and fixing bone tissue samples of different locations and densities. The adjustable fixing and rotating components 2 include two mirror-symmetrical support frames 27. The two sides of the guide plate 14 are located inside the support frames 27 and welded to them. A fixing frame 21 is fixedly connected to the bottom of the support frame 27. The fixing frame 21 is fixedly connected to the center line of the top surface of the sampling platform 11. The support frame 27 has an L-shaped structure, and an H-shaped structure is rotatably connected to one side of the support frame 27. The adjustment plate 23 has connecting blocks 25 slidably connected to both sides of its bottom, and a slider 24 is rotatably connected between the two connecting blocks 25. It can be flexibly adjusted according to different parts, densities and microstructures of bone samples. By adjusting the spacing of the clamping device, the depth and position of the sampling area can be precisely controlled. This allows for targeted sampling of bone tissues of different parts and densities (such as cortical bone, spongy bone, etc.), thereby improving the representativeness and accuracy of the samples. At the same time, a fixing strip 22 is slidably connected through the bottom of the slider 24. The fixing strip 22 is fixedly connected to the fixing frame 21. The adjustment plate 23 limits the connecting blocks 25 laterally, and the fixing strip 22 limits the slider 24 longitudinally. An adjustment block 29 is engaged between two adjustment rods 210. A drive rod 28 is fixedly connected through the center of the adjustment block 29. Two limiting strips 212 are welded to the outer wall of the end of the drive rod 28 away from the adjustment block 29. At the same time, a limiting plate 215 is fixedly connected to the end of the drive rod 28 away from the limiting strips 212.

[0024] like Figures 2-8As shown, a plurality of rubber blocks 216 arranged symmetrically in a circular pattern are fixedly connected to the side of the limiting plate 215 away from the drive rod 28, and a mounting base 217 is slidably connected to the end of the drive rod 28 away from the adjusting block 29. The mounting base 217 is fixedly installed on the support frame 27. Bearings 211 are rotatably connected to both sides of the fixed frame 21, and the bearings 211 are located inside the fixed frame 21. The drive rod 28 and the limiting strip 212 are slidably connected to the bearings 211. Two synchronous pulleys inside the drive rod 28 are rotatably connected to the fixed frame 21, and the two synchronous pulleys inside the drive rod 28 are located at the top and bottom of the fixed frame 21, respectively. The drive rod 28 and the limiting strip 212 located on one side of the fixed frame 21 are slidably connected. There is a first synchronous belt assembly 213, and one synchronous pulley in the first synchronous belt assembly 213 is fixedly connected to the bearing 211. It can be customized according to the specific characteristics of the bone sample, so that the equipment can adapt to different types of bone tissue. This flexibility can ensure the extraction of representative samples from bone tissues of different parts or different properties, and reduce errors caused by uneven sampling. At the same time, another synchronous pulley in the first synchronous belt assembly 213 is rotatably connected to the inner wall of the fixed frame 21. The limiting strip 212 longitudinally limits one synchronous pulley in the first synchronous belt assembly 213, and the driving rod 28 rotates under the action of the limiting strip 212.

[0025] like Figures 1-10As shown, a first motor 214 is installed on one outer wall of the fixing frame 21. The output end of the first motor 214 is rotatably connected to the fixing frame 21, and the through end of the first motor 214 is fixedly connected to another synchronous pulley in the first synchronous belt assembly 213. At the same time, the synchronous belt in the drive rod 28 is rotatably connected to the fixing frame 21 without intersecting. The double threaded rod 26 is fixedly connected to the synchronous pulley located at the top of the fixing frame 21 in the drive rod 28. A second motor 219 is installed at the bottom of the fixing frame 21. The output end of the second motor 219 is rotatably connected to the fixing frame 21, and the through end of the second motor 219 is fixedly connected to the synchronous pulley located at the bottom of the fixing frame 21 in the drive rod 28. The adjusting rod 210 is slidably connected to the adjusting block 29, and the adjusting rod 210 moves the adjusting block 29 laterally, which can achieve efficient positioning of the sample. With multi-point sampling, it can complete the extraction of multiple samples in a shorter time and efficiently sample bone samples from different directions and depths. This efficiency is especially useful when a large number of samples are needed for microscopic analysis or statistical research, which can greatly improve work efficiency. The two sliders 24 are threadedly connected to the double threaded rods 26, and the two ends of the double threaded rods 26 are rotatably connected to the inner wall of the fixed frame 21. At the same time, the double threaded rods 26 are threaded through but do not intersect with the guide plate 14. The middle of the double threaded rods 26 is fixedly connected to the second synchronous belt assembly 218, and the top two sides of the adjusting plate 23 are fixedly connected to the adjusting rods 210. This not only allows for adjustment of the clamping distance, but also allows for sampling of bone samples from multiple angles by rotation. By rotating, the device can cover more sampling areas, ensuring the diversity and comprehensiveness of the samples.

[0026] like Figures 2-8As shown, the adjustable fixed rotating assembly 2 has a multi-directional rotating assembly 3 welded to its top for drilling bone samples from multiple angles. The multi-directional rotating assembly 3 includes a first connecting frame 31 welded and fixed to the fixed frame 21, and a cross rod 32 is rotatably connected between the two ends of the first connecting frame 31 away from the fixed frame 21. A first gear 310 and a second gear 311 are respectively fixedly connected through the adjacent ends of the cross rod 32. A second rack 312 is meshed with one side of the second gear 311, and the side of the second rack 312 away from the second gear 311 is connected to the second connecting frame 310. The second connecting frame 33 provides a through-sliding connection, while the second connecting frame 33 limits the second rack 312. A transverse hydraulic rod 313 is located at the bottom of the second rack 312, supporting drilling at multiple angles. This allows operators to extract bone samples from different directions and depths as needed. Extracting samples from different directions helps to more comprehensively reflect the characteristics of bone tissue, ensuring the comprehensiveness and representativeness of the sampling. The transverse hydraulic rod 313 is fixedly installed to the second connecting frame 33, and the telescopic end of the transverse hydraulic rod 313 is through-slidingly connected to the second connecting frame 33. The hydraulic rod 313 is connected and fixed to the second rack 312 at its through end, and the first gear 310 meshes with the first rack 39 on one side. Simultaneously, the side of the first rack 39 away from the first gear 310 is slidably connected to the first connecting frame 31. The first connecting frame 31 limits the movement of the first rack 39, and a longitudinal hydraulic rod 38 is provided at the top of the first rack 39. This allows for sample acquisition from different directions, better reflecting the microstructural characteristics of bone tissue, thus providing more accurate data for subsequent research. The longitudinal hydraulic rod 38 and the first connecting frame 31... The longitudinal hydraulic rod 38 is installed and fixed. The telescopic end of the longitudinal hydraulic rod 38 is slidably connected to the first connecting frame 31, and the telescopic end of the longitudinal hydraulic rod 38 is fixedly connected to the first rack 39. At the same time, the other two ends of the cross rod 32 are rotatably connected to the second connecting frame 33. A lifting hydraulic rod 34 is installed at the center of the bottom surface of the second connecting frame 33, and the telescopic end of the lifting hydraulic rod 34 is fixedly connected to the frame 35. At the same time, a servo motor 36 is installed inside the frame 35. The output end of the servo motor 36 is rotatably connected to the frame 35, and a drill rod 37 is fixedly installed at the telescopic end of the servo motor 36.

[0027] The working principle of this embodiment is as follows: after placing the whole device on the table, the bone sample is placed between the two limiting plates 215, and the electronic components on the top of the sampling platform 11 are operated in sequence by operating the control panel 12.

[0028] The second motor 219 drives the second synchronous belt assembly 218 to rotate, causing the double threaded rod 26 to rotate. This causes the two sliders 24 to slide in opposite directions on the fixed bar 22. During the movement of the sliders 24, the connecting blocks 25 on both sides of the sliders 24 rotate relative to the sliders 24. At the same time, the connecting blocks 25 slide relative to the adjusting plate 23, so that the adjusting plate 23 rotates towards the bone sample with the connection point with the support frame 27 as the origin.

[0029] When the adjustment plate 23 rotates, the two adjustment rods 210 on the top of the adjustment plate 23 move synchronously, thereby moving the adjustment block 29 toward the bone sample. This causes the drive rod 28 to slide within the mounting base 217 and the bearing 211, while the limiting strip 212 slides within the bearing 211. This causes the two limiting discs 215 and their rubber blocks 216 to clamp and fix the bone sample, after which the second motor 219 stops running.

[0030] Then, the first motor 214 on one side of the fixing frame 21 drives the first synchronous belt assembly 213 for transmission. Under the action of the limiting strip 212, the drive rod 28 can rotate. At the same time, the adjusting block 29 rotates within the adjusting rod 210. Under the clamping force of the two limiting discs 215, the bone sample can be rotated synchronously to the sampling area, and then the first motor 214 stops running.

[0031] Then, the lifting hydraulic rod 34 and the servo motor 36 operate simultaneously. The lifting hydraulic rod 34 drives the frame 35 to move downward toward the bone sample, while the servo motor 36 drives the drill rod 37 to rotate and drill the bone sample. After drilling, the powder or debris of the bone sample falls onto the guide plate 14 under the action of gravity, and then gradually slides to both sides, and then falls into the collection box 13 at the bottom of the sampling platform 11 for collection.

[0032] When multiple locations of bone samples need to be sampled, the longitudinal hydraulic rod 38 and the transverse hydraulic rod 313 can operate simultaneously or intermittently. The operation of the longitudinal hydraulic rod 38 drives the first rack 39 to move up and down, which in turn causes the first gear 310 to rotate, thereby causing the cross rod 32 and its bottom connecting assembly to rotate with the connection point between the cross rod 32 and the first connecting frame 31 as the origin.

[0033] When the horizontal hydraulic rod 313 moves, it drives the second rack 312 to move, causing the second rack 312 to mesh along the circumferential direction of the second gear 311. This allows the second connecting frame 33 and its bottom connecting assembly to rotate around the connection point with the cross rod 32 as the origin. This enables the second connecting frame 33 and its bottom connecting assembly to complete multi-angle and multi-directional sampling in the same position and direction, greatly improving the sampling efficiency.

[0034] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
