Description

Technical Field

[0001] The present invention relates to the technical field of sample collection, and specifically relates to a sampling device for osteoporotic bone samples. Background Art

[0002] Osteoporosis is a common bone disease. With the aging of the population and the extension of life expectancy, its incidence rate is constantly rising. Identifying bone density and bone structure is an important means to measure the severity of osteoporosis and evaluate the fracture risk. In animal experiments and research, bone sample sampling is one of the important methods to evaluate bone density and bone structure.

[0003] A Chinese patent proposed a sampling device for osteoporotic bone samples, with the publication number CN221148079U, which includes a base. A vertical plate is fixedly connected to the base. A motor is fixedly connected to one side of the vertical plate. The output end of the motor is fixedly connected to a threaded rod, and the threaded rod is rotatably connected to the vertical plate. A threaded block is threadedly connected to the threaded rod. A limiting rod is fixedly connected to the vertical plate, and the threaded block is slidably connected to the limiting rod. One end of the limiting rod is fixedly connected to a first mounting plate. A first cylinder is fixedly connected to the first mounting plate. The output end of the first cylinder is fixedly connected to a first connecting rod, and the first connecting rod passes through and slides on the first mounting plate. The end of the first connecting rod away from the first cylinder is fixedly connected to a second mounting plate. A second cylinder is connected to the second mounting plate, and the output end of the second cylinder is fixedly connected to a second connecting rod.

[0004] By applying components such as a bone drill, a clamping block on the steel needle, and a collector, the above device realizes accurate, efficient, and pollution-free bone sample sampling. However, there is still a problem that a large amount of bone dust will be generated when the drill bit drills the bone sample. If these dusts are not processed in time, it will not only cause waste of bone samples, but also pollute the working environment and may pose a hazard to the health of operators.

[0005] Therefore, the design is highly practical, and the dust cover will come into contact with the upper surface of the bone sample one step ahead of the drill bit. With the settings of the sleeve plate, the second slider, the second chute, the second slide bar, and the third spring, the dust cover can remain stationary on the upper surface of the drilling area of the bone sample, while the drill bit continues to drill downward. The bone dust generated during drilling is enclosed in the dust cover and will not splash to the outside. By adding a fan to the cavity of the drill bit, the air flow power can be enhanced, and the bone dust can be more effectively sucked into the cavity and filtered through the filter cotton cloth. When the drill bit drills out of the bone sample, the fan stops running, and the bone dust on the filter cotton cloth automatically falls onto the partition in the cavity due to gravity. At this time, the fifth motor starts to drive the scraper to rotate, and the scraper can scrape and throw the bone dust on the partition towards the air inlet, so that the bone dust can be discharged through the air inlet and fall into the filter hopper, effectively avoiding the waste of samples caused by the splashing of bone dust and the harm to the health of workers due to the pollution of the working environment.

[0019] 2. The present invention, through the arrangement of the first slider, the first slide groove, the first slide rod, the first spring, the second spring, the vibration motor and the mounting frame, enables the screen plate to vibrate, filter and screen the drilled bone sample that falls into the filter bucket, so that the screen plate can effectively remove impurities and particles in the bone sample to ensure the purity of the sample.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. Embodiment 1

[0026] Combination Figures 1-12, the present invention provides a technical solution: a sampling device for osteoporotic bone samples, including a workbench 1 and a support frame 2. A positioning mechanism 3, a drilling mechanism 4 and a filtering mechanism 5 are arranged on the support frame 2, and a collection mechanism 6 is arranged on the workbench 1. The drilling mechanism 4 includes a cylinder 409, a third motor 410 and a drill bit 411. A dust-proof mechanism 7 is arranged on the cylinder 409, the third motor 410 and the drill bit 411.

[0027] Referring to Figure 2 and Figure 3 , it is further obtained that the positioning mechanism 3 includes a moving frame 304. One end of the moving frame 304 is rotatably provided with a hand-twisting rod 305. A driving gear 306 is fixedly sleeved on the hand-twisting rod 305. Fixed blocks 307 are fixedly arranged on both sides of the moving frame 304. A lead screw 308 is rotatably arranged on the fixed block 307. One end of the lead screw 308 rotatably penetrates through the fixed block 307 and is fixedly connected with a driven gear 309 meshed with the driving gear 306. A moving seat 310 that is slidably connected with the moving frame 304 is threadedly connected to the lead screw 308. A rubber clamping block 311 is fixedly arranged on the moving seat 310. A screw sleeve 312 is fixedly penetrated through the moving frame 304. A hand-twisting screw 313 is threadedly connected to the screw sleeve 312. A silica gel plate 314 is rotatably arranged at the bottom of the hand-twisting screw 313. A bidirectional lead screw 301 is rotatably arranged on the support frame 2. A first motor 302 is fixedly arranged at one end of the support frame 2. One end of the bidirectional lead screw 301 rotatably penetrates through the support frame 2 and is fixedly connected with the output shaft of the first motor 302. The moving frame 304 is threadedly connected to the bidirectional lead screw 301. A guide rod 303 is fixedly arranged inside the support frame 2. The moving frame 304 is slidably connected to the guide rod 303.

[0028] Specifically, the distance between the two moving frames 304 is adjusted according to the length of the bone sample. During adjustment, the first motor 302 is controlled to rotate the bidirectional lead screw 301, so that the two moving frames 304 can move towards each other under the action of the thread and the guiding action of the guide rod 303. After adjustment, the bone sample is placed inside the two moving frames 304. Then, the hand-twisting rod 305 is rotated to drive the driving gear 306 to drive the driven gear 309 to rotate, so that the driven gear 309 drives the lead screw 308 to rotate. Under the threaded connection action of the lead screw 308 and the moving seat 310, the moving seat 310 can drive the rubber clamping block 311 to move and cooperate with the moving frame 304 to tightly clamp the bone sample. After that, the hand-twisting screw 313 is rotated, so that the silica gel plate 314 moves downward under the threaded action of the hand-twisting screw 313 and the screw sleeve 312 and presses the upper surface of the bone sample. The settings of the silica gel plate 314 and the rubber clamping block 311 can increase the contact friction with the bone sample and improve the clamping tightness. At the same time, the flexible characteristics of the silica gel plate 314 and the rubber clamping block 311 enable the positioning mechanism 3 to well adapt to bone samples with various shapes and can reduce damage to the bone samples.

[0029] Refer to Figures 9-11 , and further obtain that the drilling mechanism 4 further includes a fixed frame 401 fixedly arranged on the support frame 2. One end of the fixed frame 401 is fixedly provided with a connecting frame 402. A moving groove 403 is formed in the connecting frame 402.

One end of the threaded rod 404 rotatably penetrates through the moving groove 403 and is fixedly connected to the output shaft of the second motor 405. A moving block 407 that is in threaded connection with the threaded rod 404 and is slidably connected to the moving groove 403 is arranged on the threaded rod 404. A sliding plate 406 is fixedly arranged at the bottom of the moving block 407. The air cylinder 409 is fixedly arranged at the bottom of the sliding plate 406. Limiting grooves 408 that are slidably connected to the sliding plate 406 are formed on both sides of the connecting frame 402. A third motor 410 is fixedly arranged at the bottom of the output rod of the air cylinder 409. An installation sleeve 412 is fixedly arranged at the bottom of the output shaft of the third motor 410. A plug 413 that is inserted into the installation sleeve 412 is fixedly arranged on the drill bit 411. Fixing holes 414 are formed in the installation sleeve 412 and the plug 413. A bolt 415 is inserted into the fixing hole 414. One end of the bolt 415 penetrates through the fixing hole 414 and is threadedly connected with a nut 416.

[0030] Specifically, after the bone sample is fixed, drill bits 411 of different sizes can be selected according to different sampling requirements. When replacing, the bolt 415 and the nut 416 are removed to separate the installation sleeve 412 from the plug 413, and then the drill bit 411 can be removed and replaced. After installing the required drill bit 411, the second motor 405 is controlled to rotate the threaded rod 404. Under the threaded action of the moving block 407 and the threaded rod 404, the sliding plate 406 can slide along the limiting groove 408 and drive the drill bit 411 to move. After moving the drill bit 411 above the sampling part of the bone sample, the air cylinder 409 is controlled to move the drill bit 411 downward. When the drill bit 411 contacts the sampling part of the bone sample, the drilling and collection of the bone sample can start.

[0031] Refer to Figure 4 and Figure 5, it is further obtained that the filtering mechanism 5 includes a support plate 503 fixedly arranged on the support frame 2, a filter bucket 501 is fixedly arranged at one end of the support plate 503, a discharge pipe 502 is connected to the bottom of the filter bucket 501, an ultraviolet lamp ring 512 is fixedly arranged at the bottom of the discharge pipe 502, a screen plate 504 is slidably arranged in the filter bucket 501, a first slider 505 is fixedly arranged on the side surface of the screen plate 504, a first slide groove 506 slidably connected to the first slider 505 is opened in the filter bucket 501, a first slide rod 507 slidably connected to the first slider 505 is fixedly arranged in the first slide groove 506, a first spring 508 and a second spring 509 fixedly arranged between the first slider 505 and the first slide groove 506 are sleeved on the first slide rod 507, a mounting frame 510 is fixedly arranged at the bottom of the screen plate 504, and a vibration motor 511 is fixedly arranged at the bottom of the mounting frame 510.

[0032] Specifically, the drill bit 411 penetrates into the bone sample to take a sample, and the drilled bone sample falls onto the screen plate 504 in the filter bucket 501. Through the arrangement of the first slider 505, the first slide groove 506, the first slide rod 507, the first spring 508, the second spring 509, the vibration motor 511 and the mounting frame 510, the screen plate 504 can vibrate, filter and screen the drilled bone sample, effectively removing impurities and particles in the bone sample to ensure the purity of the sample. The filtered bone sample is discharged through the discharge pipe 502 under the guidance of the filter bucket 501. At the same time, through the arrangement of the ultraviolet light ring 512, the bone sample can be sterilized and disinfected when discharged to prevent cross infection of the bone sample.

[0033] See also Figures 6-8 , it is further obtained that the collecting mechanism 6 includes a base 601 fixedly arranged on the workbench 1, a baffle 602 is fixedly arranged on the base 601, a groove 603 is opened on the base 601, a rotating rod 604 is rotatably arranged in the groove 603, a rotating disk 605 is fixedly arranged on the rotating rod 604, a placement groove 606 is opened on the rotating disk 605, a collecting dish 614 is placed between the placement groove 606 and the baffle 602, a dust cover 615 is provided on the collecting dish 614, a fourth motor 607 is fixedly arranged in the groove 603, a rotating wheel 608 is fixedly arranged on the output shaft of the fourth motor 607, a fixed disk 609 and a fixed column 610 are fixedly arranged on the rotating wheel 608, an intermittent wheel 611 is fixedly sleeved on the rotating rod 604, an arc groove 613 slidably connected to the fixed disk 609 is opened on the intermittent wheel 611, and a toggle groove 612 slidably connected to the fixed column 610 is opened on the intermittent wheel 611.

[0034] Specifically, before drilling the bone sample, a plurality of collecting dishes 614 are placed in the placement groove 606 provided on the rotating disk 605, and the rotating wheel 608 is rotated by controlling the fourth motor 607. When the rotating wheel 608 rotates, the fixed disk 609 rotates synchronously, and the fixed column 610 on the rotating wheel 608 performs a circular motion with the fixed disk 609 as the axis. When the fixed column 610 rotates, it can slide into the toggle groove 612 on the intermittent wheel 611. With the rotation of the fixed column 610, the intermittent wheel 611 can rotate intermittently, and at the same time, the fixed disk 609 slides in contact with the arc groove 613 provided on the intermittent wheel 611, and the intermittent wheel 611 drives the rotating disk 609 on the rotating rod 604. 5 is intermittently rotated, so that the placed collection dish 614 can be rotated to the bottom of the discharge pipe 502 at the bottom of the filter bucket 501, so that the drilled bone sample can fall into the collection dish 614 for storage. When drilling other parts of the bone sample, the fourth motor 607 drives the rotating disk 605 to rotate again, so that the empty collection dish 614 is rotated to the bottom of the discharge pipe 502 for collecting the material. At this time, the dust cover 615 can be used to cover the collection dish 614 that has collected the bone sample to ensure the purity of the sample. With the collection of bone samples again and again, the collected collection dish 614 can be rotated to the exit of the baffle 602 to wait for the staff to take the material.

[0035] See also Figure 10 and Figure 12 , further obtained, the dustproof mechanism 7 includes a sleeve 701 fixedly sleeved on the output rod of the cylinder 409, a second slider 702 is fixedly arranged on the side surface of the sleeve 701, a dust cover 703 is slidably sleeved on the sleeve 701, a second slide groove 704 slidably connected to the second slider 702 is provided in the dust cover 703, a second slide rod 705 slidably connected to the second slider 702 is fixedly arranged in the second slide groove 704, and a third spring 706 fixedly arranged between the second slider 702 and the second slide groove 704 is sleeved on the second slide rod 705; a cavity 707 is provided in the drill bit 411, a fixing ring 708 is fixedly arranged in the cavity 707, and a bracket 709 is fixedly arranged in the fixing ring 708 A fan 710 is fixedly installed in the bracket 709, an air outlet 711 connected to the cavity 707 is opened on the drill bit 411, and the air outlet 711 is located above the fan 710, a filter cotton cloth 712 is fixedly installed in the cavity 707 below the fan 710, a partition 713 is fixedly installed in the cavity 707 below the filter cotton cloth 712, an air inlet 716 connected to the cavity 707 is opened on the surface of the drill bit 411 close to the partition 713, and a fifth motor 714 is fixedly installed at the bottom of the partition 713, and the output shaft of the fifth motor 714 rotatably penetrates the partition 713, and a scraper 715 slidably connected to the top of the partition 713 is fixedly installed on the output shaft of the fifth motor 714.

[0036] Specifically, when the drill bit 411 moves downward for drilling, the dust cover 703 will contact the upper surface of the bone sample one step ahead of the drill bit 411. As the drill bit 411 continues to drill downward, the second slider 702 on the sleeve plate 701 can slide downward along the surface of the second slide bar 705 in the second chute 704. At the same time, the second slider 702 squeezes the third spring 706 downward, enabling the dust cover 703 to remain stationary on the upper surface of the drilling part of the bone sample, while the drill bit 411 continues to drill downward. The bone dust generated by drilling is enclosed within the dust cover 703 and will not splash to the outside. While the drill bit 411 is drilling, the fan 710 in the fixed ring 708 within the cavity 707 starts to operate. Through the settings of the air inlet 716 and the air outlet 711, the airflow generated by the fan 710 can quickly suck the bone dust within the dust cover 703 into the cavity 707 through the air inlet 716 and filter it through the filter cotton cloth 712 within the cavity 707. When the drill bit 411 drills out of the bone sample and extends below the bone sample, the fan 710 stops operating. The bone dust on the filter cotton cloth 712 automatically drops onto the partition plate 713 within the cavity 707 due to gravity. At this time, the fifth motor 714 starts to drive the scraper 715 to rotate. The scraper 715 can scrape the bone dust on the partition plate 713 and fling it towards the air inlet 716, enabling the bone dust to be discharged through the air inlet 716 and drop into the filter hopper 501, effectively avoiding the problems of sample waste and environmental pollution caused by the splashing of bone dust.
