Description

Technical Field

[0001] The present invention relates to the technical field of cell extraction, and more specifically, to a bone marrow cell extraction device based on artificial intelligence. Background Art

[0002] Bone marrow cells are the general term for a class of cells in the bone marrow, which include hematopoietic stem cells, bone marrow stromal cells, macrophages, adipocytes, etc.; bone marrow cells are hematopoietic organs that can produce pluripotent hematopoietic stem cells and are the origin of all blood cells; bone marrow cells are composed of various cells and connective tissues and are a soft spongy or fatty tissue. They interact in the bone marrow to maintain the normal production and differentiation of blood cells.

[0003] However, since the puncture site is usually at the posterior superior iliac spine, the puncture path is relatively long, resulting in that the existing bone marrow cell extraction device is prone to mix with more other tissues during the puncture sampling process and needs to be separately separated after the extraction is completed, thereby reducing the extraction efficiency and increasing the labor burden of the extraction personnel. Summary of the Invention

[0004] The present invention provides a bone marrow cell extraction device based on artificial intelligence to solve the problem that the existing bone marrow cell extraction device is prone to mix with more other tissues during the puncture sampling process and needs to be separately separated after the extraction is completed, thereby reducing the bone marrow extraction efficiency.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0010] Preferably, a suction assembly is provided at the top end of the storage cylinder. The suction assembly includes a control cylinder connected to the top end of the storage cylinder. The outer diameter of the control cylinder is smaller than the inner diameter of the storage cylinder, and a negative pressure hole is opened on the bottom wall of the control cylinder.

[0011] Preferably, a retaining ring is provided at the top end of the inner wall of the control cylinder. A pair of through slots are opened at the bottom end of the retaining ring. A pair of baffles are slidably clamped at the bottom end of the retaining ring. The clamping position of the baffles is perpendicular to the position where the through slots are located.

[0012] Preferably, the two baffles are connected by a connecting shaft. A second piston is connected to the bottom end of the connecting shaft. A groove is provided at the bottom end of the second piston. The upper surface of the second piston is in contact with the bottom surface of the retaining ring through a spring.

[0013] Preferably, a driving assembly is provided at the top end of the outer tube. The driving assembly includes a pair of connecting blocks provided on the outer side of the top end of the outer tube. A clamping groove is opened on each of the two connecting blocks. A cover plate is slidably clamped between the two clamping grooves. The thickness of the cover plate is equal to the height difference between the outer tube and the top end of the storage cylinder. An end hole is opened at the top end of the clamping groove. The longitudinal distance between the bottom end of the clamping groove and the end hole is equal to the thickness of the cover plate.

[0014] Preferably, a bracket is slidably clamped on the top end of the cover plate along the circumferential direction. A second telescopic rod is connected to the top end of the bracket. The output end of the second telescopic rod is connected to a sleeve. A directional block is coaxially connected to the top end of the connecting shaft.

[0015] Preferably, both the first telescopic rod and the second telescopic rod are controlled by an artificial intelligence system. The control information standards of the first telescopic rod include the puncture depth, the needle specification, and the puncture time. The control information standards of the second telescopic rod include the patient's height and weight, the type of the patient's disease, and the patient's age and disease history.

[0016] The principle and beneficial effects of this technical solution:

[0017] (1) The separation component set in the present invention can separately separate other components that enter the tip of the needle during the puncture of the outer tube, thereby reducing the doping amount of other tissues in the bone marrow extract, and thus improving the extraction efficiency of the device. Before using the separation component for tissue separation, first insert the tip of the needle into the bone marrow extraction position, and then shorten the first telescopic rod by a certain length according to the size and specification of the tip of the needle. The first telescopic rod will drive the first piston to move upward to draw the tissue in the tip of the needle into the storage cylinder. When the first telescopic rod stops shortening, spray adhesive through the nozzle to block the tip of the needle and the outer tube, and then drive the rotating plate to rotate 180 degrees by the magnetic block. Rotate the outer tube so that the storage tube is located below the outer tube. At this time, other tissues will gradually flow towards the interface between the connecting tube and the outer tube. During the upward movement of the first piston, the connecting rod will be gradually pulled upward. Since a push plate is connected to the outside of the connecting rod, and a compression pad connected to one side of the push plate is connected to the inner wall of the connecting tube, the connecting rod will squeeze the compression pad to contract and open the interface between the connecting tube and the outer tube, allowing the tissue to flow into the storage tube. After flowing for a period of time, the locking state of the second telescopic rod can be released and the first telescopic rod can be extended by a certain length. After extension, reset the rotating plate by the magnetic block, and then drive the first telescopic rod to shorten until it resets, so that the rotating plate pushes the tissue in the outer tube into the storage tube. At this time, the tissue separation is completed.

[0018] (2) The suction component set in the present invention can perform negative pressure suction on the bone marrow, and at the same time can temporarily store the aspirated bone marrow by inverting the storage cylinder after the suction is completed, thereby reducing the working intensity of medical staff. When using the suction component to perform negative pressure suction on the bone marrow, before puncture, rotate the cover plate 90 degrees along the end hole opened at the top of the card slot to the horizontal direction, and then slide the cover plate vertically downward until the cover plate is completely clamped into the slot at the top of the storage cylinder. At this time, drive the second telescopic rod connected to the top of the cover plate through the bracket to extend, so that the sleeve connected to the output end of the second telescopic rod is sleeved on the orientation block coaxially connected to the top of the connecting shaft until a pair of baffles provided on the outside of the connecting shaft are disengaged from the clamping with the bottom end of the retaining ring. Then drive the bracket to rotate 90 degrees along the top of the cover plate, so that the orientation block drives the baffle to rotate 90 degrees synchronously, and then the device can be used for puncture. After completing the tissue separation operation, drive the second telescopic rod to shorten, and the spring will pull the connecting shaft upward through the second piston, so that the device performs negative pressure suction on the bone marrow through the negative pressure holes on the inner bottom wall of the control cylinder.

[0019] (3) The artificial intelligence control system in the present invention can assist in adjusting and controlling the first telescopic rod and the second telescopic rod according to various information of the patient to enhance the use effects of the separation component and the suction component. When controlling the first telescopic rod to separate non-bone marrow tissues, estimate the total amount of tissues to be separated according to the puncture depth and the needle specifications, and at the same time estimate the additional tissue amount introduced during the puncture process due to adjusting the puncture angle through the puncture time. Control the first telescopic rod according to the sum of the above tissue amounts to improve the separation accuracy;

[0020] When bone marrow cell aspiration is required, the amount of bone marrow tissue that needs to be aspirated is determined based on the patient's height, weight, age and disease type, and the second telescopic rod is controlled to shorten to aspirate the bone marrow tissue. During the aspiration and sampling process, the needle tip sampling position can be fine-tuned based on the patient's medical history to reduce the number of bone marrow sampling punctures to improve extraction efficiency.

DETAILED DESCRIPTION

[0028] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments:

[0029] Example:

[0030] like Figures 1 to 6As shown in the figure, the present invention provides a bone marrow cell extraction device based on artificial intelligence, which includes an outer tube 2 and a separation component. A storage cylinder 18 is arranged inside the outer tube 2. The separation component includes a storage tube 1 arranged outside the outer tube 2. A first telescopic rod 9 is arranged at the top of the storage tube 1. The bottom end of the first telescopic rod 9 is connected with a first piston 10. The first piston 10 is slidably clamped inside the storage tube 1. A connecting tube 12 is connected to the outside of the first piston 10. The free end of the connecting tube 12 is directly communicated with the bottom end of the outer tube 2. A control component is arranged at the interface between the connecting tube 12 and the outer tube 2.

[0031] As Figure 1 and Figure 3 shown, the control component includes a compression pad 14 arranged at the interface between the connecting tube 12 and the outer tube 2. A push plate 15 is arranged on one side of the compression pad 14. A connecting rod 11 is connected to the bottom end of the first piston 10. The connecting rod 11 is connected with the push plate 15.

[0032] As Figure 1 and Figure 6 shown, a rotating plate 31 is rotatably clamped at the bottom end of the connecting rod 11. The rotating plate 31 is rotatably clamped on the inner bottom wall of the outer tube 2. A magnetic block 30 is arranged on the inner bottom wall of the outer tube 2. One side of the rotating plate 31 is in contact with the magnetic block 30. The rotating plate 31 is semicircular.

[0033] As Figure 6 shown, a conical block 33 is arranged at the bottom end of the rotating plate 31. A nozzle is arranged on the side wall of the through hole 32. A medical adhesive that can be quickly cured is stored in the cavity sac connected to the nozzle.

[0034] As Figure 1 , Figure 2 and Figure 4 shown, a suction component is arranged at the top of the storage cylinder 1. The suction component includes a control cylinder 17 connected to the top of the storage cylinder 1. The outer diameter of the control cylinder 17 is smaller than the inner diameter of the storage cylinder 18. A negative pressure hole 8 is opened on the inner bottom wall of the control cylinder 17.

[0035] As Figure 4 and Figure 5 shown, a retaining ring 26 is arranged at the top end of the inner wall of the control cylinder 17. A pair of through slots 22 are opened at the bottom end of the retaining ring 26. A pair of baffles 23 are slidably clamped at the bottom end of the retaining ring 26. The clamping position of the baffles 23 is perpendicular to the position where the through slots 22 are located.

[0036] As Figure 4 and Figure 5 shown, the two baffles 23 are connected by a connecting shaft 28. The bottom end of the connecting shaft 28 is connected with a second piston 16. A groove is arranged at the bottom end of the second piston 16. The upper surface of the second piston 16 is in contact with the bottom surface of the retaining ring 26 through a spring 27.

[0037] As Figure 1 , Figure 2 and Figure 5As shown in the figure, a driving assembly is provided at the top end of the outer tube 2. The driving assembly includes a pair of connecting blocks 20 provided on the outer side of the top end of the outer tube 2. Card slots 21 are formed on both of the two connecting blocks 20. A cover plate 7 is slidably clamped between the two card slots 21. The thickness of the cover plate 7 is equal to the height difference between the outer tube 2 and the top end of the storage cylinder 18. An end hole 19 is formed at the top end of the card slot 21. The longitudinal distance between the bottom end of the card slot 21 and the end hole 19 is equal to the thickness of the cover plate 7.

[0038] As Figure 2 and Figure 5 shown in the figure, a bracket 5 is slidably clamped on the top end of the cover plate 7 in the circumferential direction. A second telescopic rod 3 is connected to the top end of the bracket 5. The output end of the second telescopic rod 3 is connected to a sleeve 6. The top end of the coupling shaft 28 is coaxially connected to an orientation block 25. The sleeve 6 is slidably clamped on the outside of the orientation block 25.

[0039] The suction assembly can perform negative pressure suction on the bone marrow. At the same time, after the suction is completed, the suctioned bone marrow can be temporarily stored by inverting the storage cylinder 18, thereby reducing the working intensity of medical staff. When using the suction assembly to perform negative pressure suction on the bone marrow, before puncture, the cover plate 7 needs to be rotated 90 degrees along the end hole 19 formed at the top end of the card slot 21 to the horizontal direction, and then the cover plate 7 is slid down vertically until the cover plate 7 is completely clamped into the slot at the top end of the storage cylinder 18. At this time, the second telescopic rod 3 connected to the top end of the cover plate 7 through the bracket 5 is driven to extend, so that the sleeve 6 connected to the output end of the second telescopic rod 3 is sleeved on the orientation block 25 coaxially connected to the top end of the coupling shaft 28 until a pair of baffles 23 provided on the outside of the coupling shaft 28 are disengaged from the clamping with the bottom end of the retaining ring 26. Then, the bracket 5 is driven to rotate 90 degrees along the top end of the cover plate 7, so that the orientation block 25 drives the baffle 23 to rotate 90 degrees synchronously, and then the device can be used for puncture. After the tissue separation operation is completed, the second telescopic rod 3 is driven to shorten, and the spring 27 will pull the coupling shaft 28 upward through the second piston 16, so that the device performs negative pressure suction on the bone marrow through the negative pressure holes 8 on the inner bottom wall of the control cylinder 17;

[0040] After the suction is completed, the storage cylinder 18 is slowly inverted, and the suctioned bone marrow of the device will slide down along the inner wall of the storage cylinder 18 and finally be stored in the gap between the control cylinder 17 and the storage cylinder 18.

[0041] As Figure 1 shown in the figure, both the first telescopic rod 9 and the second telescopic rod 3 are controlled by an artificial intelligence system. The control information standards of the first telescopic rod 9 include the puncture depth, the needle head specification, and the puncture time. The control information standards of the second telescopic rod 3 include the patient's height and weight, the patient's disease type, and the patient's age and disease history.

[0042] The artificial intelligence control system can assist in adjusting and controlling the first telescopic rod 9 and the second telescopic rod 3 according to various information of the patient to enhance the use effect of the separation component and the aspiration component. When controlling the first telescopic rod 9 to separate non-bone marrow tissue, the total amount of tissue to be separated is estimated based on the puncture depth and the needle tip specification. At the same time, the additional tissue amount introduced due to adjusting the puncture angle during the puncture process is estimated through the puncture time. The first telescopic rod 9 is controlled according to the sum of the above tissue amounts to improve the separation accuracy;

[0043] When bone marrow cells need to be aspirated, the amount of bone marrow tissue to be aspirated and sampled is determined according to the patient's height, weight, age, and disease type of the patient. The second telescopic rod 3 is controlled to shorten to aspirate the bone marrow tissue. During the aspiration sampling process, the sampling position of the needle tip can be finely adjusted in combination with the patient's medical history to reduce the number of bone marrow sampling punctures and improve the extraction efficiency.

[0044] The specific usage method and function of this embodiment:

[0045] In the present invention, the provided separation component can separately separate other components entering the needle tip during the puncture of the outer tube 2, thereby reducing the doping amount of other tissues in the bone marrow extract, and thus improving the extraction efficiency of the device. Before using the separation component for tissue separation, first insert the needle tip into the bone marrow extraction position, and then shorten the first telescopic rod 9 by a certain length according to the size and specification of the needle tip. The first telescopic rod 9 will drive the first piston 10 to move upward to suck the tissue in the needle tip into the storage cylinder 18. When the first telescopic rod 9 stops shortening, the adhesive is sprayed through the nozzle to block the needle tip and the outer tube 2. Then, the rotating plate 31 is driven to rotate 180 degrees by the magnet 30, and the outer tube 2 is rotated so that the storage tube 1 is located below the outer tube 2. At this time, other tissues will gradually flow to the interface between the connecting tube 12 and the outer tube 2. During the upward movement of the first piston 10, the connecting rod 11 will be gradually pulled upward. Since the outer side of the connecting rod 11 is connected with the push plate 15, and at the same time, the compression pad 14 connected to one side of the push plate 15 is connected to the inner wall of the connecting tube 12, the connecting rod 11 will squeeze the compression pad 14 to contract and open the interface between the connecting tube 12 and the outer tube 2, so that the tissue flows into the storage tube 1. After flowing for a period of time, the locking state of the second telescopic rod 3 can be released and the first telescopic rod 9 can be extended by a certain length. After extension, the rotating plate 31 is reset by the magnet 30, and then the first telescopic rod 9 is driven to shorten until it is reset, so that the rotating plate 31 pushes the tissue in the outer tube 2 into the storage tube 1. At this time, the tissue separation is completed;

[0046] After the separation is completed, the first telescopic rod 9 is fully reset, and the conical block is used to break through the wall barrier formed by the adhesive.

[0047] The above are only embodiments of the present invention, and common general technical solutions and / or features in the solutions are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent.
