Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a tumor effusion extraction device. Background Art

[0002] In the field of medical device technology, the development of tumor fluid extraction devices has evolved from traditional manual puncture and extraction to semi-automatic and even fully automated equipment. Traditionally, the extraction of tumor fluid mainly relies on manual operation by doctors. A manual puncture needle is used to enter the fluid accumulation area in the patient's body, and then a syringe or negative pressure device is used for extraction. This method is complicated to operate and requires a high level of experience and skills from the doctor. Due to the limitations of manual operation, it is often difficult to ensure the accuracy and safety of each puncture.

[0003] With the continuous advancement of medical technology, tumor fluid extraction devices have gradually achieved semi-automation. For example, by introducing robotic arms or electric puncture devices to assist doctors in puncture operations, these semi-automatic devices have reduced the operating burden of doctors to a certain extent and improved the efficiency and safety of puncture. However, existing semi-automatic extraction devices still have many shortcomings, especially in terms of the stability and controllability of the puncture process. Existing technologies often find it difficult to achieve ideal results. For example, although some electric puncture devices can automatically advance the needle, due to the lack of a precise control system, they are often unable to adjust the puncture depth and speed in real time according to the patient's specific situation, thereby increasing the risk of tissue damage. Therefore, staff need to improve them. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) Through the arrangement of a fixed bracket, an absorption tube, a connecting box, a sleeve tube, a partition ring, an electromagnetic coil, a connector, a needle, a magnetic ring and a controller, the extraction of tumor effusion can be realized with precision and automation. The fixed bracket provides a stable support base for the entire device, ensuring stability during operation; the absorption tube can achieve length adjustment and tension maintenance through the damping shaft and the winding rod in the connecting box, thereby enhancing the flexibility of operation; the electromagnetic drive design of the electromagnetic coil and the magnetic ring replaces the traditional manual puncture method, and the current size and direction can be precisely adjusted by the controller to accurately control the puncture depth and speed of the needle, significantly improving the accuracy and safety of the puncture, and effectively avoiding the risk of tissue damage caused by improper operation.

[0018] (2) The design of the micro-bracket, movable rod, mounting block, turbine blade, connecting rod and spiral scraper solves the technical problem of easy clogging of the needle during the extraction of effusion. The micro-bracket provides a stable rotational support for the movable rod to ensure the reliability of its operation; when the effusion flows through the connector, the fluid power drives the turbine blade to rotate, which in turn drives the movable rod and spiral scraper to rotate on the inner wall of the needle, removing tumor tissue or fibrin deposits attached to the tube wall in real time, effectively preventing the blockage of the lumen. This self-cleaning mechanism does not require external power and can be achieved only by relying on the flow of effusion.

[0019] (3) Through the design of adhesive tape, lap plate, sliding groove, sliding block, negative pressure extraction machine, liquid inlet pipe, discharge pipe, handle, collection box, receiving pipe, connecting pipe, sealing cover, observation glass, control panel, charging interface and fixed bottom plate, the whole process operation from puncture positioning to waste liquid collection is optimized. The adhesive tape ensures that the sleeve is firmly fixed on the patient's body surface, improving the stability of the puncture process; the sliding track formed by the lap plate and the sliding groove enables the sliding block to be adjusted laterally, facilitating the precise positioning and convenient disassembly and assembly of the negative pressure extraction machine; the negative pressure extraction machine is connected to the absorption pipe through the liquid inlet pipe, generating controllable negative pressure to efficiently extract the accumulated fluid, and transporting it to the collection box through the discharge pipe. Its transparent observation glass facilitates real-time monitoring of the properties of the accumulated fluid, and the bottom sealing cover facilitates the safe disposal of medical waste. The control panel integrates the operation interface, and the battery connected to the charging interface powers the system. The anti-slip pad of the fixed bottom plate further ensures the stability of the equipment, significantly improving the convenience of operation and clinical safety, while meeting the requirements of hygiene standards.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0029] Example 1:

[0030] See also Figures 1 to 7 As shown, a tumor fluid extraction device includes: a fixing bracket 1;

[0031] An absorption tube 2 is inserted into the top of the fixed bracket 1, and a connection box 3 is sleeved on the front end of the absorption tube 2. The inner wall of the connection box 3 is rotatably connected to a damping shaft, and the surface of the damping shaft is rotatably connected to a winding rod. The surface of the absorption tube 2 is wound around the surface of the winding rod, and a sleeve tube 4 is fixedly connected to the surface of the connection box 3.

[0032] The inner wall of the sleeve tube 4 is fixedly connected to the partition ring 5, and the inner wall of the sleeve tube 4 and the surface of the partition ring 5 are fixedly connected to the electromagnetic coil 6. The front end of the absorption tube 2 is fixedly connected to the connector 7, and the surface of the connector 7 is inserted into the inner wall of the sleeve tube 4. The front end of the connector 7 is fixedly connected to the needle 8, and the surface of the connector 7 is fixedly connected to the magnetic ring 9, and the surface of the magnetic ring 9 is inserted into the inner wall of the partition ring 5. The top of the connection box 3 is fixedly connected to the controller 10.

[0033] When in use, the fixed bracket 1 serves as the overall supporting structure to ensure the stability of the device; the absorption tube 2 is used to transmit the extracted effusion, and its front end is connected to the sleeve tube 4 through the connecting box 3. The connecting box 3 is provided with a damping shaft and a winding rod, which can adjust the length of the absorption tube 2 and maintain its tension. A partition ring 5 is fixed to the inner wall of the sleeve tube 4. The partition ring 5 and the sleeve tube 4 jointly fix the electromagnetic coil 6. When the electromagnetic coil 6 is energized, a magnetic field is generated to drive the magnetic ring 9 on the surface of the connector 7 to move; the front end of the connector 7 is connected to the needle 8. When the magnetic ring 9 is acted upon by the electromagnetic force, it drives the connector 7 and the needle 8 to move axially to achieve precise puncture. The controller 10 adjusts the current size and direction of the electromagnetic coil 6, thereby accurately controlling the puncture depth and speed of the needle 8. Replacing traditional manual puncture with electromagnetic drive not only improves the accuracy and controllability of puncture, but also reduces the risk of tissue damage caused by improper operation. At the same time, the characteristics of non-contact transmission of the magnetic field are used to avoid mechanical wear and pollution problems, thereby achieving efficient and safe tumor effusion extraction as a whole.

[0036] During use, the micro-bracket 11 is fixed to the connector 7 and the inner wall of the needle 8, providing rotational support for the movable rod 12; the mounting block 13 is fixed to the surface of the movable rod 12, and a plurality of turbine blades 14 are provided on the mounting block 13. When the effusion flows through the connector 7, the fluid dynamics and the negative pressure attraction drive the turbine blades 14 to rotate, thereby driving the movable rod 12 to rotate; the movable rod 12 is connected to the spiral scraper 16 through the connecting rod 15, so that the spiral scraper 16 rotates on the inner wall of the needle 8, scraping off the tumor tissue or fibrin deposits attached to the inner wall of the needle 8 in real time to prevent the lumen from being blocked, and the structure does not require external power, and can achieve self-cleaning only by relying on the flow of effusion, which not only avoids the problem of decreased efficiency of traditional suction devices due to blockage, but also reduces the operation of frequently replacing needles, significantly improving the continuity and stability of effusion extraction, and reducing the risk of cross infection.

A sealing cover 28 is threadedly connected to the bottom of the collecting box 25, and an observation glass 29 is fixedly connected to the surface of the collecting box 25. A control panel 30 is fixedly connected to the top of the fixed bracket 1, a charging port 31 is fixedly connected to the top of the back of the fixed bracket 1, a battery is fixedly connected to the inner wall of the fixed bracket 1, and the battery and the control panel 30 are electrically connected to each other, a fixed base plate 32 is fixedly connected to the bottom of the fixed bracket 1, and a non-slip pad is fixedly connected to the bottom of the fixed base plate 32.

[0039] During use, the adhesive tape 17 is used to fix the sleeve tube 4 to the patient's body surface to ensure the stability of the puncture process; the overlapping plate 18 and the sliding groove 19 form a sliding track, so that the sliding block 20 can be adjusted in position laterally, thereby driving the negative pressure extraction machine 21 to be easily disassembled and assembled. The negative pressure extraction machine 21 is connected to the absorption tube 2 through the liquid inlet pipe 22, generating controllable negative pressure to extract the accumulated fluid, and transporting the liquid to the collection box 25 through the discharge pipe 23. The collection box 25 is connected to the discharge pipe 23 through the receiving tube 26 and the connecting tube 27. Its transparent observation glass 29 is convenient for real-time monitoring of the properties of the accumulated fluid. The bottom sealing cover 28 facilitates the safe disposal of medical waste. The control panel 30 integrates the operation interface, and the battery connected through the charging port 31 powers the entire system. The fixed bottom plate 32 is equipped with an anti-slip pad to ensure the stability of the equipment during operation, realizing the optimization of the entire process from puncture positioning, negative pressure suction to waste liquid collection, which not only improves the convenience of operation but also ensures clinical safety and hygiene standards.

[0040] Example 4:

[0041] See also Figures 1 to 7 As shown in the figure, the patient had a large amount of malignant pleural effusion on the right side due to tumor metastasis, which led to dyspnea and decreased blood oxygen saturation. Traditional puncture and fluid extraction required manual needle insertion and was prone to needle clogging due to the viscosity of the effusion, requiring repeated operations. There is an urgent need for a fluid extraction device that can accurately puncture, automatically prevent blockage and is easy to operate.

[0042] The fixing bracket 1 is firmly placed beside the patient's bed through the anti-slip pad of the fixing base plate 32, and the controller 10 is connected to the power supply.

[0043] The puncture parameters (depth 50 mm, negative pressure -150 mmHg) are set via the control panel 30 , and the adhesive tape 17 is used to preliminarily fix the sleeve tube 4 to the surface of the patient's intercostal puncture point.

[0044] Start the controller 10, energize the electromagnetic coil 6 to generate a magnetic field, drive the magnetic ring 9 to drive the connector 7 and the needle 8 to advance at a constant speed, and adjust the tension of the absorption tube 2 by the damping shaft to ensure that the needle 8 accurately penetrates the pleura to the effusion cavity (real-time depth feedback is displayed on the control panel 30).

[0045] The negative pressure extraction machine 21 is started through the liquid inlet pipe 22. When the accumulated fluid flows into the connector 7 through the needle 8, the turbine blades 14 rotate under the action of the fluid, and the spiral scraper 16 is linked by the movable rod 12 to scrape off the fibrin adhered to the inner wall of the needle 8 to prevent blockage.

[0046] The sliding block 20 slides along the sliding groove 19 to facilitate the disassembly and assembly of the negative pressure extraction machine 21 .

[0047] The effusion enters the collection box 25 through the discharge tube 23 and the connecting tube 27. The nature of the effusion (bloody and turbid) is confirmed through the observation glass 29. The extraction is stopped when the amount reaches 800 mL.

[0048] The sealing cap 28 is unscrewed to safely dispose of the waste liquid without changing the needle and without any blockage alarm.

[0049] The electromagnetic coil 6 generates reverse current to retract the needle 8. After disinfection, the collection box 25 is disassembled and the charging interface 31 is used to charge the battery for standby use.

[0050] Working principle: The fixed bracket 1 serves as the overall supporting structure to ensure the stability of the device. The absorption tube 2 is used to transmit the extracted effusion. Its front end is connected to the sleeve tube 4 through the connecting box 3. The damping shaft and winding rod arranged in the connecting box 3 can adjust the length of the absorption tube 2 and maintain the tension; the partition ring 5 fixed on the inner wall of the sleeve tube 4 cooperates with the electromagnetic coil 6. The magnetic field generated after power is turned on drives the magnetic ring 9 on the surface of the connector 7 to move, thereby driving the connector 7 and the needle 8 to achieve precise puncture. The controller 10 accurately controls the puncture depth and speed by adjusting the current of the electromagnetic coil 6; the micro bracket 11 is fixed to the inner wall of the connector 7 and the needle 8 and provides rotation support for the movable rod 12, which drives the turbine blades when the effusion flows through the connector 7 The blade 14 rotates, driving the movable rod 12 to rotate through the mounting block 13, and the spiral scraper 16 connected to the connecting rod 15 rotates on the inner wall of the needle 8 to remove the sediment; the adhesive tape 17 fixes the sleeve tube 4 to the patient's body surface, and the sliding track composed of the lap plate 18 and the sliding groove 19 allows the sliding block 20 to be adjusted laterally, driving the negative pressure extraction machine 21 to generate negative pressure through the liquid inlet pipe 22 to extract the accumulated fluid, and transport it to the collection box 25 through the discharge pipe 23. The observation glass 29 is convenient for observing the properties of the accumulated fluid. The control panel 30 is powered by a battery connected to the charging interface 31, and the anti-slip pad of the fixed bottom plate 32 ensures stable operation. The whole system realizes the full process automation operation from precise puncture, self-cleaning suction to safe collection.
