Description

Technical Field

[0001] The invention relates to the technical field of centrifuges, in particular to a centrifugal extraction device for collagen sutures. Background Art

[0002] Medical sutures are common linear materials, widely used in various surgical operations to suture wounds and connect tissues. With the continuous advancement of science and technology, suture materials have gone through four generations of development; the first generation was silk thread, the second generation was catgut, the third generation was chemically synthesized absorbable suture (PGA, PGLA, PLA), and the fourth generation was collagen absorbable suture.

[0003] Collagen liquid is needed in the production process of collagen sutures, and centrifugal extraction equipment is needed to extract the collagen liquid in the extract.

[0004] During the use of existing centrifugal extraction equipment, when the centrifugal force drives the extracted materials to adhere to the equipment wall, the extracted materials may clog the filter holes of the wall, affecting the extraction effect of the equipment, and after use, it is necessary to manually insert the cleaning mechanism into the equipment to clean the inner wall of the equipment, which is troublesome to clean. The existing extraction equipment has great limitations when in use. For small centrifugal equipment, most of them perform centrifugal extraction on samples in test tubes. For some larger centrifugal equipment, most of them perform centrifugal extraction on the extract contained in the mixed material after stirring and mixing the materials in the centrifugal cabin. When the centrifugal extraction equipment rotates to throw the materials onto the wall, it is impossible to push the materials attached to the wall back into the drum for secondary centrifugation, so that the extract in the material is not fully extracted, resulting in waste of resources. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a collagen suture centrifugal extraction device to solve the technical problems that the extracted material is easy to clog the filter holes, the centrifugal material can only be extracted once with low efficiency, and the centrifugal extraction machine is troublesome to clean.

[0006] To achieve the above object, the present invention provides the following technical solution: A collagen suture centrifugal extraction device, comprising a workbench, a centrifugal chamber is provided at the top of the workbench, a centrifugal rotor is provided in the middle of the centrifugal chamber, and a cleaning and scraping mechanism is provided on the outer side of the centrifugal rotor;

[0007] The cleaning and scraping mechanism comprises an arrow gear rod, a bevel gear block, a push-pull gear plate, a first scraper, a second scraper, a connecting ring plate and a third scraper;

[0008] The arrow gear rod is located at the top of the middle part of the centrifugal rotor, and the front and rear sides of the arrow gear rod are meshed and connected with a push-pull gear plate, one end of the push-pull gear plate is rotatably connected with the first scraper, one end of the bottom of the push-pull gear plate is fixed with an arc spring sheet, and one end of the top of the arrow gear rod is meshed and connected with a conical gear block;

[0009] The second scraper is located obliquely above the centrifugal rotor, a cross-connecting clamp is slidably connected above the second scraper, a connecting ring plate is provided above one end of the second scraper, and a third scraper is rotatably connected to the top of the cross-connecting clamp.

[0010] The present invention is further configured such that a limiting support block is welded to one end of the top of the push-pull tooth plate, one end of the limiting support block is clamped with a positioning block, the positioning block is located above the first scraper and is rotatably connected to the top of the first scraper, and the shape of the first scraper in a top view is arc-shaped.

[0011] The present invention is further configured such that the bottom of the arc-shaped spring sheet is welded to one end of the first scraper, and a support hoop block is fixed to the bottom of one end of the first scraper.

[0012] The present invention is further configured such that a positioning groove is provided at the connection between the positioning block and the limiting support block, and a fixing block for clamping the positioning block is provided in the positioning groove.

[0013] The present invention is further configured such that an auxiliary spring is provided between one end of the second scraper and the bottom of the connecting ring plate, the upper end of the second scraper is rotatably connected to the bottom of one end of the connecting ring plate, and the top view shape of the second scraper is arc-shaped.

[0014] The present invention is further configured such that the third scraper is located outside the centrifugal chamber, one end of the conical gear block is fixedly connected to a motor, and a protective box is provided on the outside of the motor.

[0015] The present invention is further configured such that the inner side of the connecting ring plate is rotatably connected to a hatch provided on the top of the centrifugal chamber, a docking clamp groove is provided in the middle of one end of the first scraper, and a docking clamp connecting block is fixed to the bottom of one end of the second scraper.

[0016] In summary, the present invention mainly has the following beneficial effects: it is convenient to clean the bulkhead of the centrifugal chamber after use, which is beneficial to prevent the residue in the centrifugal chamber from clogging the filter holes of the bulkhead and affecting the effect of material extraction, and is convenient to clamp and fix the test tube when the medicine in the test tube is centrifuged, and is convenient to stir the liquid during mixing to improve the mixing efficiency, and is convenient for secondary extraction of the material, which is beneficial to improve the efficiency of collagen extraction and reduce resource waste.

[0017] When the present invention cleans the bulkhead of the centrifugal cabin through the cleaning and scraping mechanism, the rotating arrow gear rod pushes a group of meshing push-pull tooth plates to slide in the direction of the bulkhead of the centrifugal cabin, thereby driving the first scraper connected to one end of the push-pull tooth plate to slide on the bulkhead of the centrifugal cabin; when the bottom end of the first scraper contacts the bulkhead, the pushing force generated between the bulkhead and the bottom of the first scraper pushes the first scraper to rotate around one end of the push-pull tooth plate in the direction of the centrifugal rotor, thereby driving the upper side of the first scraper to rotate on the second scraper, pushing the lower side of the second scraper to rotate above the inner wall of the centrifugal cabin, thereby driving the upper side of the second scraper to rotate on the connecting ring plate, and rotating. The movable second scraper drives the third scraper which is rotatably connected to the top of the cross-connected clamp through the cross-connected clamp of the upper sliding clamp to slide toward the bulkhead outside the centrifugal chamber; when the first scraper drives the second scraper to rotate and clamp onto the inner wall of the centrifugal chamber, the third scraper will be driven to clamp onto the bulkhead outside the centrifugal chamber synchronously; at this time, the rotating centrifugal rotor will drive the first scraper, the second scraper connected to the first scraper clamp and the third scraper connected to the top of the second scraper to rotate synchronously to scrape and clean the centrifugal chamber, which makes it convenient to clean the bulkhead of the centrifugal chamber after use, and helps prevent the slag in the centrifugal chamber from clogging the filter holes of the bulkhead and affecting the material extraction effect.

[0018] When clamping a test tube, the test tube to be clamped is placed against the outer wall of the centrifugal rotor, and then the toothed plate is pushed and pulled to drive the first scraper to slide onto the centrifugal rotor. When the inner surface of the first scraper is stuck to the outer side of the test tube, the first scraper and the centrifugal rotor cooperate with each other to fix the test tube clamp to the centrifugal rotor, which makes it easier to clamp and fix the test tube when the medicine in the test tube is centrifuged.

[0019] During stirring, the first scraper is pushed to the middle between the centrifugal rotor and the inside of the centrifugal chamber, so that both ends of the first scraper are not in contact with the inner wall of the centrifugal rotor and the centrifugal chamber. At this time, the rotating first scraper will stir and mix the materials in the centrifugal chamber, which makes it easier to stir the liquid when mixing and improves the mixing efficiency.

[0020] During centrifugal extraction, when the rotating centrifugal rotor throws the material onto the second scraper during the centrifugal process, the second scraper will vibrate under the action of the auxiliary spring due to the impact. The vibrating second scraper will vibrate and drain the material that falls on the second scraper to the centrifugal rotor for secondary centrifugation, which facilitates the secondary extraction of the material, helps to improve the efficiency of collagen extraction, and helps to reduce resource waste.

DETAILED DESCRIPTION

[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] The following describes an embodiment of the present invention based on its overall structure.

[0030] A centrifugal extraction device for collagen sutures, such as Figure 1-Figure 6 As shown, it includes a workbench 1 for supporting and positioning the centrifugal device, a centrifugal cabin 2 is provided at the top of the workbench 1 for storing materials, a centrifugal rotor 3 is provided in the middle of the centrifugal cabin 2 for driving the materials to rotate so that the extract in the materials is separated from the materials, and a cleaning and scraping mechanism 4 is provided on the outer side of the centrifugal rotor 3 for cleaning the cabin wall of the device or for clamping the test tube;

[0031] The cleaning and scraping mechanism 4 comprises an arrow gear rod 41, a bevel gear block 42, a push-pull gear plate 44, a first scraper 45, a second scraper 47, a connecting ring plate 49 and a third scraper 411;

[0032] The arrow gear rod 41 is located at the top of the middle part of the centrifugal rotor 3, and is used to drive the push-pull tooth plate 44 connected at the bottom to slide left and right. The front and rear sides of the arrow gear rod 41 are meshed with a push-pull tooth plate 44, which is used to adjust the distance between the first scraper 45 and the centrifugal rotor 3. One end of the push-pull tooth plate 44 is rotatably connected to the first scraper 45, which is used to scrape the inner wall of the centrifugal chamber 2 or to clamp and fix the test tube to be clamped. An arc spring sheet 46 is fixed to one end of the bottom of the push-pull tooth plate 44, which is used to reset the first scraper 45 that rotates to adjust the angle. One end of the top of the arrow gear rod 41 is meshed with a conical gear block 42, which is used to drive the arrow gear rod 41 to rotate;

[0033] The second scraper 47 is located obliquely above the centrifugal rotor 3, and is used to drain the centrifuged material or to scrape the top of the wall of the centrifugal chamber 2, or to adjust the distance between the third scraper 411 and the centrifugal chamber 2. A cross-connecting card plate 48 is slidably connected above the second scraper 47 to limit the rotation trajectory of the second scraper 47 and to push and pull the third scraper 411 to slide. A connecting ring plate 49 is provided above one end of the second scraper 47 to connect a group of second scrapers 47 and drive the second scraper 47 to rotate. The top of the cross-connecting card plate 48 is rotatably connected to the third scraper 411 to scrape and clean the outer wall of the centrifugal chamber 2. The shape of the first scraper 45 in top view is arc-shaped, and the shape of the second scraper 47 in top view is arc-shaped.

[0034] It should be pointed out that when cleaning the bulkhead of the centrifugal chamber 2, the rotating bevel gear block 42 drives the meshing arrow gear rod 41 to rotate, and the rotating arrow gear rod 41 pushes a group of meshing push-pull gear plates 44 to slide in the direction of the bulkhead of the centrifugal chamber 2, thereby driving the first scraper 45 connected to one end of the push-pull gear plate 44 to slide on the bulkhead of the centrifugal chamber 2. When the bottom end of the first scraper 45 contacts the bulkhead, the pushing force generated between the bulkhead and the bottom of the first scraper 45 pushes the first scraper 45 to rotate around the rotating shaft connected to the first scraper 45 at one end of the push-pull gear plate 44 in the direction of the centrifugal rotor, thereby driving the first scraper 45 to rotate upward toward the second scraper 45. 7, when the engaging groove provided in the middle of the upper surface of one end of the first scraper 45 contacts the bottom of the second scraper 47, the lower part of the second scraper 47 is pushed to rotate toward the upper part of the inner wall of the centrifugal chamber 2 under the restriction of the rotating shaft provided between the connecting ring plate 49 and the second scraper 47, thereby driving the upper part of the second scraper 47 to rotate toward the connecting ring plate 49 under the restriction of the rotating shaft, and the rotating second scraper 47 drives the third scraper 411 rotatably connected to the top of the cross-connecting card plate 48 through the cross-connecting card plate 48 of the upper sliding clamp to slide toward the wall of the outer side of the centrifugal chamber 2, and when the first scraper 45 rotates to be perpendicular to the bottom of the centrifugal chamber 2, the outer surface of one end of the first scraper 45 will be stuck to the centrifugal chamber 2. The first scraper 45 is pressed against the inner wall of the centrifugal chamber 2, and the second scraper 47 is pressed against the inner wall of the centrifugal chamber 2. The second scraper 47 is pressed against the inner wall of the centrifugal chamber 2, and the bottom of the second scraper 47 is pressed against the inner wall of the centrifugal chamber 2. The second scraper 47 is pressed against the inner wall of the centrifugal chamber 2, and the bottom of the second scraper 47 is pressed against the inner wall of the centrifugal chamber 2. The snap-fitting positions are fixedly connected to form an integral whole. At this time, the rotating centrifugal rotor 3 will drive the integrated first scraper 45 and the second scraper 47 to rotate along the inner wall of the centrifugal chamber 2 under the guidance of the connecting ring plate 49. The rotating second scraper 47 will drive the third scraper 411 connected to the cross-connecting card plate 48 through the cross-connecting card plate 48 provided above to rotate synchronously along the outer wall of the centrifugal chamber 2, so as to scrape and clean the inner and outer walls of the centrifugal chamber 2. When the second scraper 47 rotates, it will drive the connected connecting ring plate 49 to rotate, so as to prevent the connection between the third scraper 411 and the second scraper 47 from shaking and separating during the rotation.

[0035] When clamping the test tube, the test tube to be clamped is placed against the outer wall of the centrifugal rotor 3, and then the toothed plate 44 is pushed and pulled to drive the first scraper 45 to slide onto the centrifugal rotor 3. When the inner surface of the first scraper 45 is clamped onto the outer side of the test tube, the first scraper 45 and the centrifugal rotor 3 cooperate with each other to fix the test tube clamp onto the centrifugal rotor 3.

[0036] During stirring, the first scraper 45 is pushed to the middle between the centrifugal rotor 3 and the inside of the centrifugal chamber 2, so that both ends of the first scraper 45 are not in contact with the inner walls of the centrifugal rotor 3 and the centrifugal chamber 2. At this time, the rotating first scraper 45 will stir and mix the materials in the centrifugal chamber 2.

[0037] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 A limiting support block is welded to one end of the top of the push-pull tooth plate 44, and a positioning block 412 is clamped at one end of the limiting support block. The positioning block 412 is located above the first scraper 45 and is rotatably connected to the top of the first scraper 45. A positioning groove is provided at the connection between the positioning block 412 and the limiting support block, and a fixing block for clamping the positioning block 412 is provided in the positioning groove. The bottom of the arc-shaped spring sheet 46 is welded to one end of the first scraper 45, and a supporting hoop plate is fixed to the bottom of one end of the first scraper 45.

[0038] It can be understood that before clamping the test tube, the positioning block 412 can be rotated one hundred and eighty degrees so that the docking block on the positioning block 412 can be rotated and clamped to one end of the fixed block fixedly connected to the inner side of the positioning groove, and the positioning block 412 can be fixed to the positioning groove by the fixed block through the docking block, so that the first scraper 45 is fixed to the limiting support block to prevent the first scraper 45 from rotating. At this time, when the fixed first scraper 45 is clamped on the test tube, it is helpful to prevent the clamped test tube from shaking. The bottom of the test tube is supported by a support block plate welded to the bottom of one end of the first scraper 45.

[0039] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 An auxiliary spring 410 is provided between one end of the second scraper 47 and the bottom of the connecting ring plate 49, the upper end of the second scraper 47 is rotatably connected to the bottom of one end of the connecting ring plate 49, the inner side of the connecting ring plate 49 is rotatably connected to the hatch cover provided on the top of the centrifugal chamber 2, a docking clamp groove is provided in the middle of one end of the first scraper 45, and a docking clamp connecting block is fixed to the bottom of one end of the second scraper 47.

[0040] It should be noted that when the rotating centrifugal rotor 3 throws the material onto the second scraper 47 during the centrifugal process, the second scraper 47 is impacted and vibrates under the action of the auxiliary spring 410, and the vibrating second scraper 47 vibrates and guides the material falling on the second scraper 47 to the centrifugal rotor 3 for secondary centrifugation.

[0041] When the upper part of the first scraper 45 contacts the lower part of the second scraper 47, the docking clamp groove in the middle of the first scraper 45 will be clamped to the docking clamp connection block fixed under the second scraper 47, so that the second scraper 47 with the clamp can be driven to rotate when the first scraper 45 rotates;

[0042] In addition, multiple groups of V-shaped scraping strips are welded on the outer surfaces of the first scraper 45 and the second scraper 47 for scraping the materials on the wall of the centrifugal chamber 2 .

[0043] See also Figure 1 , Figure 2 and Figure 6 The third scraper 411 is located outside the centrifugal chamber 2, one end of the bevel gear block 42 is fixedly connected to the motor 43, and a protective box is provided outside the motor 43.

[0044] It should be noted that when in use, the power supply is connected, and the motor 43 drives the bevel gear block 42 fixedly connected to the output end to rotate, thereby driving the arrow gear rod 41 meshingly connected to the bottom of one end of the bevel gear block 42 to rotate.
