Description

Technical Field

[0001] The present invention relates to the technical field of hematology medical instruments, and in particular to a bone marrow puncture and extraction device for leukemia patients. Background Art

[0002] The bone marrow puncture and extraction device for leukemia patients is a medical device specially designed for bone marrow puncture operations on leukemia patients.

[0003] In the clinical diagnosis of leukemia, bone marrow puncture is an indispensable and key examination method, and its operation effect is directly related to the accuracy of diagnosis and the comfort of patients. At present, traditional bone marrow puncture operations are usually performed manually by medical staff. During the operation, local anesthesia is first performed, and then the puncture needle is replaced to extract the bone marrow. This process requires two punctures. Leukemia patients are relatively weak. The second puncture not only increases the patient's pain, but also may cause problems such as puncture position deviation and poor depth control due to the instability of manual operation, affecting the puncture effect and sample quality. At the same time, manual operation requires a high level of experience and skills of medical staff and is relatively difficult to operate. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the present invention aims to provide a bone marrow puncture and extraction device for leukemia patients, which can improve the degree of mechanization, avoid secondary puncture and alleviate the patient's pain.

[0005] The purpose of the present invention is achieved by adopting the following technical solutions:

[0006] A bone marrow puncture and extraction device for leukemia patients includes: a support assembly and a puncture assembly; the support assembly includes a support plate and a lifting drive device, and the lifting drive device is installed on the support plate; the puncture assembly is installed on the support plate, and the puncture assembly includes a lifting platform, an anesthesia syringe, a bone marrow syringe, a reversing valve and a puncture needle; the lifting platform is connected to the output part of the lifting drive device so that the lifting platform can approach or move away from the support plate; the anesthesia syringe and the bone marrow syringe are respectively installed on the lifting platform and supported by the lifting platform; the reversing valve has a first valve port, a second valve port, a third valve port and a valve core, the anesthesia syringe is connected to the first valve port, the bone marrow syringe is connected to the second valve port, and the puncture needle is connected to the third valve port, and the valve core selectively connects the third valve port to the first valve port or the second valve port.

[0007] Furthermore, the support plate is provided with a guide through hole, and the puncture needle is movably sleeved in the guide through hole.

[0008] Furthermore, a guide sleeve is installed in the guide through hole.

[0009] Further, the support plate is connected with a plurality of support rods.

[0010] Further, the plurality of support rods are jointly connected with a disc.

[0011] Further, the plurality of support rods are provided with first magic tapes at the bottom, the disc is provided with second magic tapes at the end face, and the first magic tapes are matched with the second magic tapes.

[0012] Further, the disc is provided with an avoiding through hole.

[0013] Further, the bone marrow puncture and extraction device for leukemia patients further comprises a positioning device, the positioning device comprises a scale plate and a pointer, the scale plate is vertically installed on the support plate, the scale plate is provided with a sliding groove, and the pointer is installed on the lifting table and is in sliding cooperation with the sliding groove.

[0014] Further, the lifting driving device is an electric telescopic rod.

[0015] Further, the bone marrow puncture and extraction device for leukemia patients further comprises a control system, and the control system is electrically connected with the electric telescopic rod.

[0016] Compared with the prior art, the beneficial effects of the present application are that:

[0017] 1. Based on the lifting driving device being installed on the support plate and the puncture assembly being installed on the support plate, the overall installation structure enables the puncture assembly to always remain stable when being driven by the lifting driving device to operate. Even after long-term use, the puncture assembly will not loosen and shake due to frequent lifting and moving, so as to always maintain a stable working state. This effectively solves the problem of inaccurate puncture needle positioning and low operation precision caused by the loose structure and unstable operation of the traditional puncture device, ensures that the target position can be accurately reached every time the puncture is performed, and greatly improves the reliability of the puncture operation. At the same time, this stable structure provides a solid foundation for completing anesthesia and bone marrow extraction in one puncture, avoids the need for secondary puncture due to unstable devices, and thus reduces the pain of patients.

[0018] 2. Based on the lifting platform being connected to the output portion of the lifting drive device, the anesthesia syringe and the bone marrow syringe are respectively installed on the lifting platform and supported by the lifting platform. This connection and support structure allows the lifting platform to remain stable during the movement towards or away from the support plate. Even after long-term use, the lifting platform will not become loose or shaken due to frequent movement; the anesthesia syringe, bone marrow syringe, and the reversing valve and puncture needle connected to it installed on the lifting platform can always maintain a stable working state. This effectively solves the problem that the needle in the traditional puncture device lacks stable support and is prone to puncture position deviation due to hand-holding or unstable movement, which may require a second puncture. It ensures the accuracy of the puncture needle position during anesthesia and bone marrow extraction, provides reliable guarantees for completing two operations with one puncture, greatly improves the stability of the puncture extraction, and also reduces the pain that may be caused to the patient by a second puncture.

[0019] 3. The reversing valve comprises a first valve port, a second valve port, a third valve port, and a valve core. The anesthesia syringe is connected to the first valve port, the bone marrow syringe is connected to the second valve port, and the puncture needle is connected to the third valve port. The valve core selectively connects the third valve port to either the first or second valve port. This integrated pathway switching structure makes the transition between anesthesia injection and bone marrow aspiration more convenient and efficient. Even after multiple consecutive operations, the valve core's switching action remains precise, preventing pathway misalignment or switching delays. The pathway connection between the anesthesia syringe, bone marrow syringe, and puncture needle remains stable and reliable. This effectively solves the problem of traditional puncture procedures requiring needle replacement or repeated tubing connections for anesthesia and bone marrow aspiration, resulting in cumbersome and time-consuming procedures. Medical staff no longer need to perform complex needle replacement or tubing disassembly between the two procedures; switching can be completed simply by adjusting the valve core, ensuring a smooth operational process, significantly shortening the overall puncture and aspiration time, and indirectly reducing patient discomfort during the puncture.

As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0031] Reference Figures 1-7The bone marrow puncture extraction device for leukemia patients comprises a support assembly 1 and a puncture assembly 2; the support assembly 1 comprises a support plate 11 and a lifting driving device 12, and the lifting driving device 12 is installed on the support plate 11; the puncture assembly 2 is installed on the support plate 11, and the puncture assembly 2 comprises a lifting table 21, an anesthetic needle cylinder 22, a bone marrow needle cylinder 23, a reversing valve 24 and a puncture needle 25; the lifting table 21 is connected with the output part of the lifting driving device 12, so that the lifting table 21 can be close to or away from the support plate 11; the anesthetic needle cylinder 22 and the bone marrow needle cylinder 23 are respectively installed on the lifting table 21 and are supported by the lifting table 21; the reversing valve 24 has a first valve port 241, a second valve port 242, a third valve port 243 and a valve core 244, the anesthetic needle cylinder 22 is connected with the first valve port 241, the bone marrow needle cylinder 23 is connected with the second valve port 242, the puncture needle 25 is connected with the third valve port 243, and the valve core 244 selectively connects the third valve port 243 with the first valve port 241 or the second valve port 242.

[0032] In the operation of bone marrow puncture extraction of leukemia patients, first, the patient is kept in a suitable position, and the puncture site is aligned below the puncture needle 25 of the device. The support plate 11 of the support assembly 1 is placed on a stable plane to provide basic support for the entire device, and the lifting driving device 12 is installed on the support plate 11 and waits for subsequent driving instructions. The puncture assembly 2 installed on the support plate 11 enters the preparation state. The lifting table 21 of the puncture assembly 2 is connected with the output of the lifting driving device 12, and the anesthetic syringe 22 and the bone marrow syringe 23 are fixed on the lifting table 21 in the preset position and are stably supported by the lifting table 21. The first valve port 241 of the reversing valve 24 is connected with the anesthetic syringe 22, the second valve port 242 is connected with the bone marrow syringe 23, the third valve port 243 is connected with the puncture needle 25, and the valve core 244 is initially in a standby switching state, and the communication path can be selected according to the operation stage. When the anesthesia operation is needed, the valve core 244 of the reversing valve 24 is adjusted to make the third valve port 243 (the third valve port 243 is connected with the puncture needle 25) communicate with the first valve port 241 (the first valve port 241 is connected with the anesthetic syringe 22). At this time, the lifting driving device 12 is started, and the output thereof drives the lifting table 21 to move towards the patient, and the puncture needle 25 moves synchronously with the lifting table 21 and gradually penetrates into the puncture site of the patient. When the puncture needle 25 reaches the preset anesthesia depth, the lifting driving device 12 stops, the anesthetic syringe 22 injects anesthetic into the patient's body through the puncture needle 25 through the communicated valve port path, and the anesthesia link is completed. After the anesthesia is completed, the puncture needle 25 does not need to be pulled out, and only by adjusting the valve core 244 of the reversing valve 24, the third valve port 243 (the third valve port 243 is connected with the puncture needle 25) can be switched to communicate with the second valve port 242 (the second valve port 242 is connected with the bone marrow syringe 23). Then, the lifting driving device 12 finely adjusts the position of the lifting table 21 as needed to ensure that the puncture needle 25 is in a suitable bone marrow extraction position. At this time, the bone marrow syringe 23 starts to extract the bone marrow through the puncture needle 25 through the communicated valve port path. During the extraction process, the lifting driving device 12 can stably keep the position of the lifting table 21 and the puncture needle 25 to avoid affecting the extraction effect due to position deviation. Through the precise driving of the lifting driving device 12 to the lifting table 21, the penetration depth and position of the puncture needle 25 can be controlled; by switching the valve core 244 of the reversing valve 24, the function conversion of anesthesia and bone marrow extraction can be completed based on the same puncture needle 25. The entire process does not need to pull out the puncture needle 25 for secondary penetration, realizes the completion of two operations at one time, effectively guarantees the continuity and stability of the puncture extraction, thereby improving the mechanization degree and reducing the pain of the patient.

[0033] Obviously, based on the lifting driving device 12 is installed on the support plate 11, the puncture assembly 2 is installed on the support plate 11. This overall mounting structure makes the puncture assembly 2 always stable when it is driven by the lifting driving device 12. Even after long-term use, the puncture assembly 2 will not loosen and shake due to frequent lifting movement, so it can always maintain a stable working state. This effectively solves the problem of inaccurate positioning of the puncture needle 25 and low operation precision caused by loose structure and unstable operation of the traditional puncture device, ensuring that the puncture can accurately reach the target position every time, greatly improving the reliability of the puncture operation. At the same time, this stable structure provides a solid foundation for completing anesthesia and bone marrow extraction in one puncture, avoiding the need for secondary puncture due to unstable device, thereby reducing the patient's pain. Based on the output part of the lifting driving device 12 connected to the lifting platform 21, the anesthesia needle cylinder 22 and the bone marrow needle cylinder 23 are respectively installed on the lifting platform 21 and supported by the lifting platform 21. This connection and support structure makes the lifting platform 21 always stable during the movement of approaching or moving away from the support plate 11. Even after long-term use, the lifting platform 21 will not loosen and shake due to frequent movement; the anesthesia needle cylinder 22, the bone marrow needle cylinder 23 and the reversing valve 24, the puncture needle 25 connected thereto installed on the lifting platform 21 can always maintain a stable working state. This effectively solves the problem of deviation of the puncture position caused by lack of stable support of the needle in the traditional puncture device, which may require secondary puncture, ensuring the accuracy of the position of the puncture needle 25 during anesthesia and bone marrow extraction, providing a reliable guarantee for completing two operations in one puncture, greatly improving the stability of puncture extraction, and reducing the pain of the patient caused by secondary puncture. Based on the reversing valve 24 having a first valve port 241, a second valve port 242, a third valve port 243 and a valve core 244, the anesthesia needle cylinder 22 is connected to the first valve port 241, the bone marrow needle cylinder 23 is connected to the second valve port 242, the puncture needle 25 is connected to the third valve port 243, and the valve core 244 selectively connects the third valve port 243 to the first valve port 241 or the second valve port 242. This integrated path switching structure makes the operation conversion of anesthesia injection and bone marrow extraction more convenient and efficient. Even after multiple consecutive operations, the switching action of the valve core 244 can still be accurate, without misplacement or delay of the path, and the path connection between the anesthesia needle cylinder 22, the bone marrow needle cylinder 23 and the puncture needle 25 is always stable and reliable. This effectively solves the problem of complicated and time-consuming operation steps caused by the need to replace the needle or repeatedly connect the pipeline during anesthesia and bone marrow extraction in the traditional puncture operation. Medical staff do not need to replace the needle or disassemble the pipeline between the two operations, but only need to adjust the valve core 244 to complete the switching, ensuring the smoothness of the operation process, significantly shortening the overall puncture extraction time, and indirectly reducing the discomfort of the patient during the puncture process.

[0034] Preferably, in the embodiment, the support plate 11 is provided with a guide through hole 111, and the puncture needle 25 is movably sleeved in the guide through hole 111. The provision of the guide through hole 111 provides a fixed movement track for the puncture needle 25, and the puncture needle 25 can always keep aligned with the puncture site when moving axially along the guide through hole 111 under the driving of the lifting platform 21. Even if there is slight vibration when the lifting drive device 12 is running, or the weight of the needle cylinder carried by the lifting platform 21 is deviated, the guide through hole 111 can limit the radial swing of the puncture needle 25, and ensure the accuracy of the puncture direction. For the bone marrow puncture of leukemia patients, the positioning accuracy of the puncture site directly affects the operation safety. If the puncture needle 25 deviates, it may deviate from the bone marrow cavity and cause sampling failure. The structure reduces the positioning error through physical constraint, and provides a basic guarantee for one-time puncture success.

[0035] Preferably, in the embodiment, the guide through hole 111 is provided with a guide sleeve 112. The provision of the guide sleeve 112 can reduce the friction when the puncture needle 25 moves, so that the puncture needle 25 moves more smoothly and stably along the guide sleeve 112 under the driving of the lifting platform 21, and reduces the occurrence of jamming. Even after long-term and frequent use, the wear degree of the guide sleeve 112 is much lower than that of the case where the support plate 11 directly contacts, and the guide sleeve 112 can keep good sliding performance for a long time, and ensure that the puncture needle 25 always moves accurately along the preset track, thereby providing a long-term guarantee for the stability of the puncture operation. Moreover, the provision of the guide sleeve 112 can also make the device better adapt to puncture needles 25 of different specifications. When puncture needles 25 of different diameters are needed, only the guide sleeve 112 with the corresponding inner diameter needs to be replaced, without the need to modify the guide through hole 111 of the support plate 11 or replace the support plate 11, thereby greatly improving the universality and flexibility of the device. For leukemia patients, medical staff may select puncture needles 25 of different specifications according to the specific condition and puncture site. This convenient adaptation method simplifies the operation process, saves preparation time, and can quickly perform puncture operation for patients, thereby indirectly reducing the waiting anxiety of patients. In addition, the guide sleeve 112 can also compensate for the gap error between the puncture needle 25 and the guide through hole 111 through its own slight deformation, thereby further improving the stability and accuracy of the movement of the puncture needle 25.

[0036] Preferably, in the present embodiment, the support plate 11 is connected with a plurality of support rods 13. The arrangement of multiple support rods 13 can provide multi-point support for the support plate 11 from different positions, and can evenly distribute the weight of the support plate 11, the lifting drive device 12, the puncture assembly 2 and other components installed thereon to the support surface (such as an operating table or a hospital bed). Compared with a single support structure, this multi-point support mode can effectively resist the overturning moment generated during the operation of the device. When the lifting drive device 12 moves the puncture assembly 2, the center of gravity of the device will change, and the plurality of support rods 13 can balance the shift of the center of gravity through coordinated force, thereby preventing the support plate 11 from tilting or shaking. For the puncture operation of leukemia patients, stable support of the device is a prerequisite for precise operation, which can prevent the puncture needle 25 from deviating due to shaking of the equipment and reduce the risk of secondary puncture.

[0037] Preferably, in the present embodiment, the plurality of support rods 13 are jointly connected with a disc 14. The combination of the disc 14 and the plurality of support rods 13 can improve the flexibility of body position adaptation of the device. The disc 14 increases the contact area between the device and the support surface (such as a hospital bed or an operating table), and in combination with the height adjustment function of the support rods 13, the device can remain stable in different scenarios; whether the patient is supine or lateral, medical staff can adjust the support rods 13 and the disc 14 to form stable support and quickly align the puncture needle 25 with the puncture site. This fast and stable body position adaptation reduces the deviation of the puncture position caused by improper placement of the device and reduces the probability of first puncture failure. At the same time, the stable support of the disc 14 can prevent the device from suddenly shifting during operation, ensuring that the puncture needle 25 always remains in the correct position during the switching process between anesthesia and bone marrow extraction, without the need for secondary penetration, thereby effectively reducing the pain of leukemia patients.

[0038] Preferably, in the present embodiment, the bottom of the plurality of support rods 13 is provided with a first magic tape 131, the end face of the disc 14 is provided with a second magic tape 142, and the first magic tape 131 cooperates with the second magic tape 142. The paste cooperation mode of the magic tape makes the connection operation of the support rod 13 and the disc 14 simple and efficient. Medical staff do not need to use tools, but only need to press the first magic tape 131 at the bottom of the support rod 13 against the second magic tape 142 at the end face of the disc 14 to complete the installation, and can easily peel off when disassembling. This convenient installation method can quickly complete the assembly and adjustment of the device, reducing the preoperative preparation time. For leukemia patients, the reduction of preoperative waiting time can reduce their psychological anxiety, and also improves the efficiency of the overall operation of the mechanized process.

[0039] Preferably, in the present embodiment, the disc 14 is provided with a through hole 141. The provision of the through hole 141 allows the disc 14 to not reserve additional space for the puncture needle 25 to pass, making the overall structure of the device more compact. As the bottom load-bearing structure of the support assembly 1, if there is no through hole 141, a sufficient distance needs to be left between the edge of the disc 14 and the puncture needle 25 to avoid interference, which will result in an increase in the lateral size of the device and occupy more operating space. The through hole 141 allows the puncture needle 25 to pass through the central area of the disc 14, so that the support rods 13 are evenly distributed around the puncture needle 25, ensuring stability of support and reducing the floor area occupied by the device. For the puncture operation of leukemia patients, a compact structure can reduce the occupation of space around the patient's bed, making it easier for medical staff to operate nearby (such as observing the puncture state and adjusting equipment parameters), improving the convenience of operation, and indirectly improving the smoothness of mechanical operation.

[0040] Preferably, in the present embodiment, the device for bone marrow puncture and extraction of leukemia patients further comprises a positioning device 3, which comprises a scale plate 31 and a pointer 32. The scale plate 31 is vertically installed on the support plate 11, and the scale plate 31 is provided with a sliding groove 311. The pointer 32 is installed on the lifting platform 21 and is in sliding cooperation with the sliding groove 311. In this way, the pointer 32 slides in the sliding groove 311 of the scale plate 31 when the lifting platform 21 moves synchronously, and the scale pointed to by the pointer 32 can intuitively reflect the moving distance of the lifting platform 21, i.e. the penetration depth of the puncture needle 25. The bone marrow puncture of leukemia patients has very high depth requirements; too shallow may not be able to obtain a bone marrow sample, and too deep may damage the surrounding tissue, and the scale of the scale plate 31 can provide a quantitative reference for medical staff. Medical staff can determine the target depth in advance according to the patient's age, body size, etc., and accurately control the stopping time of the puncture needle 25 by observing the position of the pointer 32 during the mechanical driving of the lifting platform 21, avoiding puncture failure caused by inaccurate depth control. This quantitative control reduces the dependence on the experience of medical staff and improves the degree of mechanization and standardization of operation. Moreover, the sliding groove 311 of the scale plate 31 can constrain the sliding of the pointer 32, indirectly enhancing the stability of the movement of the lifting platform 21. When the pointer 32 slides in the sliding groove 311, it will produce a slight guiding effect on the lifting platform 21 through the contact surface, which can assist in limiting the lateral shaking of the lifting platform 21. Although this guiding effect is weaker than a dedicated guiding structure, it can reduce the depth deviation caused by slight vibration of the equipment during the critical stage when the puncture needle 25 approaches the target depth. For leukemia patients with weak bodies, this improvement in stability in detail can reduce the risk of puncture, thereby indirectly reducing the patient's pain.

[0041] Preferably, in the present embodiment, the lifting driving device 12 is an electric telescopic rod. The electric telescopic rod can realize precise adjustment of the telescopic amount through electric current or pulse signal, and when the output part drives the lifting platform 21 to move, the movement distance and speed of the puncture needle 25 can be accurately controlled. The bone marrow texture of leukemia patients may differ due to the disease condition, and the force and depth need to be adjusted according to the actual situation during puncture. The electric telescopic rod can be programmed to allow the puncture needle 25 to penetrate at a stable speed, avoiding sudden acceleration of the puncture needle 25 due to manual operation force, and reducing the stimulation to the patient's skeleton and surrounding tissues. At the same time, precise telescopic amount control can ensure that the puncture needle 25 reaches the target position according to the preset depth, avoiding over-shallow puncture or over-deep puncture. Moreover, the mechanical structure of the electric telescopic rod has good fatigue resistance and can maintain stable output precision after long-term frequent use. Traditional manual driving or pneumatic driving methods may have power decay due to component wear, resulting in gradual deviation of the puncture depth. The driving components of the electric telescopic rod have good sealing and little wear, and cooperate with the supporting structure of the lifting platform 21 to ensure the stable movement of the anesthetic needle cylinder 22 and the bone marrow needle cylinder 23 for a long time. This stability ensures that the device always maintains consistent accuracy during multiple puncture operations, indirectly providing equipment support for continuously avoiding secondary puncture.

[0042] Preferably, in the present embodiment, the bone marrow puncture and extraction device for leukemia patients further comprises a control system electrically connected to the electric telescopic rod. The control system can realize digital control of the electric telescopic rod. Medical staff can preset parameters such as puncture depth and lifting speed through the control system, and the electric telescopic rod will accurately drive the lifting platform 21 to move according to the set instructions. For example, during the anesthesia stage, a slower pushing speed can be set to allow the anesthetic to be evenly injected; when switching to the bone marrow extraction stage, the speed can be adjusted to a suitable sampling rhythm through the control system. This digital control avoids fluctuations in manual operation force and visual errors, ensuring that the puncture needle 25 moves strictly according to the preset trajectory each time, reducing the risk of puncture failure due to operation deviation. For leukemia patients, accurate puncture can avoid the need for secondary puncture due to insufficient depth or positional deviation, thereby reducing the patient's pain. Moreover, the control system has overload protection and abnormal warning functions. When the electric telescopic rod encounters abnormal resistance during driving (such as when the puncture needle 25 hits the hard tissue of the bone), the control system will immediately trigger the protection mechanism to control the electric telescopic rod to stop moving and issue a warning, avoiding damage to the patient's tissues or equipment due to continuous force. This intelligent protection mechanism mitigates the risk of "overexertion" in traditional manual operation, adding a safety line to the puncture operation. At the same time, the control system can record the parameters and process data of each puncture, facilitating subsequent tracing and operation optimization, further improving the reliability of the device and providing support for long-term and stable avoidance of secondary puncture.
