Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a pressure-applying device for a balloon catheter for treating vascular embolism caused by thrombosis. Background Art

[0002] Vascular intervention is an important treatment modality for revascularization of vascular stenosis. Balloon catheters are typically used as the primary device in vascular intervention. Balloon catheter thrombectomy can be used to treat vascular embolism, removing emboli such as thrombi and plaques that have become lodged within the vessel.

[0003] However, in clinical practice, thrombosis combined with stenosis or old thrombosis is very common, and the recanalization rate of ordinary balloon thrombectomy alone is very low. To address this symptom, it is generally necessary to use a high-pressure balloon to dilate the stenosis before removing the thrombus. However, these traditional devices have some limitations. For example, they cannot effectively deal with complex or stubborn thrombi, which makes thrombectomy time too long and leads to poor treatment effect. In addition, the precise control and real-time feedback mechanism of existing equipment are insufficient, making the pressure adjustment during the operation not flexible and accurate enough. These problems not only affect the success rate of treatment, but may also increase the risk and discomfort of patients. Summary of the Invention

[0007] Preferably, a second micro pressure sensor is fixedly connected to the outside of the air supply tube. The second micro pressure sensor is installed inside the rear balloon and in close contact with the inner wall of the rear balloon to ensure that the pressure changes in the rear balloon can be accurately sensed.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1.

At the same time, the first catheter also drives the front balloon to move and push the embolism into the memory metal mesh bag. The embolism extraction head is externally connected to a suction pump, which cooperates with the suction pump installed on one side of the embolism extraction head to extract the embolism into the memory metal mesh bag and flow out along the second catheter for easy embolism removal operation. When encountering a large thrombus, the memory metal mesh bag can be contracted to entrain and draw back the thrombus. When the embolism is removed, the front balloon is reduced, so that the third spring piece pushes the second guide cover back from the bent reset, thereby causing the first titanium alloy claw and the second titanium alloy claw to contract for easy recovery.

[0017] 2. In the present application, when the memory metal mesh bag is opened, the memory metal mesh bag pushes the first spring piece and the movable sleeve to move, so that the movable sleeve pushes the support sleeve to drive the medicine storage ball membrane to move. When the medicine storage ball membrane moves, it approaches the extrusion ring, and the extrusion ring squeezes the medicine storage ball membrane, thereby squeezing the thrombolytic drug inside the medicine storage ball membrane, which is conducive to the thrombolytic agent passing through the memory metal mesh bag to the embolism and dissolving the thrombus. In combination with the above-mentioned thrombus removal component, the thrombus can be better removed.

[0018] 3. This application improves the accuracy and effectiveness of vascular embolization procedures through real-time monitoring and feedback adjustment. The physician enters preset pressure parameters during the initial setup phase, and the system automatically monitors and adjusts the balloon pressure during the procedure, ensuring the safety and stability of the treatment process. The automated closed-loop feedback mechanism reduces human error and enhances patient safety. The final data processing and recording function provides valuable reference for subsequent analysis and improvement. BRIEF DESCRIPTION OF THE DRAWINGS

A protective sleeve 20 is fixedly connected to the rear side of the pusher head 19. The protective sleeve 20 is slidably connected to the outside of the first catheter 1. The protective sleeve is pushed by the pusher head 19 20 moves, the first guide cover 21 is fixedly connected to the rear side of the protective cover 20, the two connecting pipes 27 are fixedly connected to both sides of the first guide cover 21, the first guide cover 21 is adapted to the front support ring 22, and the rear support ring 24 is adapted to the second guide cover 26. A positioning ring 31 is fixedly connected to the outside of the first guide tube 1, and a plurality of third elastic pieces 32 are fixedly connected to one side of the positioning ring 31.

A plurality of first titanium alloy claws 23 and a plurality of second titanium alloy claws 25 are staggered.

[0034] The front end outer side of the first catheter 1 is provided with an embolism removal component for assisting in the removal of emboli. The embolism removal component includes a first guide cover 21, a front support ring 22, a rear support ring 24 and a second guide cover 26. The outer side of the front support ring 22 is fixedly connected to a plurality of first titanium alloy spring claws 23 in an annular array. The outer side of the rear support ring 24 is fixedly connected to a plurality of second titanium alloy spring claws 25 in an annular array. The rear support ring 24 is fixedly connected to the front end outer side of the first catheter 1. Connecting pipes 27 are fixedly connected on both sides between the first guide cover 21 and the rear support ring 24. A medicine releasing component is provided on the front end outer side of the third catheter 3. The component includes a movable sleeve 10, multiple first spring fragments 11, a support sleeve 12 and a medicine storage ball membrane 13. The medicine storage ball membrane 13 is wrapped with thrombolytic drugs. Multiple first spring fragments 11 are fixedly connected to the outside of the movable sleeve 10 in a ring array. The front end of the fourth catheter 4 is fixedly connected to a support ring 15, and one side of the support ring 15 is fixedly connected to multiple second spring fragments 16. One side of the multiple second spring fragments 16 is fixedly connected to an extrusion ring 14. The extrusion ring 14 corresponds to one end of the medicine storage ball membrane 13. The outside of the rear end of the air supply pipe 5 is fixedly connected to a second air inlet head 29, and the second air inlet head 29 is connected to the air supply pipe 5.

[0035] When using this solution, the doctor will insert the guide wire into the blood vessel and move the first catheter 1 around the outside of the guide wire, so that the front end of the first catheter 1 drives the front balloon 8 to move to the embolism site. The first air inlet head 28 and the second air inlet head 29 are externally connected to a gas injection mechanism, which consists of a high-precision air pressure pump, a gas flow regulating valve, and connecting pipes. The air pressure pump can provide a stable and adjustable air pressure source, and the gas flow regulating valve is used to accurately control the flow rate and injection speed of the gas. In addition, the first catheter 1, the second catheter 2, and the third catheter 3 are externally connected to a transmission controller, which is equipped with gears to drive the first catheter 1, the second catheter 2, and the third catheter 3 to move. The doctor controls the corresponding installed knobs to drive the first catheter 1, the second catheter 2, and the third catheter 3 to move precisely.

[0036] By pushing the third catheter 3 to drive the fourth catheter 4 and the air delivery tube 5 to move, the air delivery tube 5 drives the rear balloon 6 to move to the front section of the blood vessel embolization. The doctor controls the gas injection mechanism to output gas to the inside of the air delivery tube 5 through the second air inlet head 29 to inflate the inside of the rear balloon 6, so that the rear balloon 6 expands and contacts the inner wall of the blood vessel. Then, the doctor drives the first catheter 1 forward, so that the first catheter 1 drives the exhaust head 7 and the front balloon 8 forward, so that the front balloon 8 passes through the embolism, and the gas injection mechanism outputs gas to the inside of the first catheter 1 through the first air inlet head 28, so that the gas flows out from the exhaust groove 17, thereby controlling the front balloon 8. The front balloon 8 expands, so that the front balloon 8 supports the blood vessel at the rear section of the embolism, thereby blocking both ends of the blood vessel embolism and preventing the embolism from falling off and moving to other positions. The second catheter 2 drives the memory metal mesh bag 9 to move, so that the memory metal mesh bag 9 extends from the inside of the fourth catheter 4, so that the second catheter 2 pops out into a funnel shape after losing its restraint. During the opening process of the front balloon 8, the front balloon 8 pushes the push head 19 and the protective sleeve 20 to move, and then the protective sleeve 20 drives the first guide cover 21 to move. During the movement, the first guide cover 21 drives the two connecting tubes 27 to move, so that the connecting tube 27 drives the front branch ring 22 and The second guide cover 26 moves synchronously. Since the initial positions of the front support ring 22 and the rear support ring 24 are located inside the first guide cover 21 and inside the second guide cover 26 respectively, when the front support ring 22 and the second guide cover 26 move, the front support ring 22 is separated from the first guide cover 21, and the rear support ring 24 is separated from the second guide cover 26, so that the multiple first titanium alloy claws 23 on the outside of the front support ring 22 are opened outward, and the multiple second titanium alloy claws 25 on the outside of the rear support ring 24 are opened outward, and the first guide ring 1 moves together with the first guide ring 1. The first titanium alloy claws 23 and the second titanium alloy claws 25 push and cut the embolism to prevent The embolism is solidified and difficult to fall off. At the same time, the first catheter 1 also drives the front balloon 8 to move, pushing the embolism into the memory metal mesh bag 9. The embolism extraction head 33 is externally connected to a suction pump, and the suction pump installed on one side of the embolism extraction head 33 cooperates with the suction pump installed on one side of the embolism extraction head 33 to pull the embolism into the memory metal mesh bag 9 and flow out along the second catheter 2, which is convenient for embolism removal operation. When encountering a large thrombus, the memory metal mesh bag 9 can be contracted and the thrombus can be entrained and drawn back. When the embolism removal is completed, the front balloon 8 is reduced in size, so that the third spring piece 32 pushes the second guide cover 26 back from the bent reset, so that the first titanium alloy claw 23 and the second titanium alloy claw 25 are contracted, which is convenient for recovery.

[0037] When the memory metal mesh bag 9 is opened, it pushes the first spring piece 11 and the movable sleeve 10 to move, causing the movable sleeve 10 to push the support sleeve 12, which in turn moves the drug-storage sphere membrane 13. As the membrane 13 moves, it approaches the extrusion ring 14, causing the extrusion ring 14 to squeeze the membrane 13. The membrane 13 is made of polylactic-co-glycolic acid copolymer, a biodegradable polymer composed of lactic acid and glycolic acid linked by ester bonds. This material has excellent biocompatibility, mechanical properties, and a tunable degradation rate. The resulting film or microsphere can deform under certain conditions, such as exposure to body fluids or external forces, to release the drug inside. The degradation products, lactic acid and glycolic acid, can be excreted from the body through the body's metabolic pathways, thereby squeezing out the thrombolytic drug inside the membrane 13. This facilitates the thrombolytic drug's passage through the memory metal mesh bag 9 to the embolic site, dissolving the thrombus. Combined with the aforementioned thrombus removal assembly, thrombus removal can be achieved.

[0038] like Figure 11 As shown, the present invention provides a thrombus treatment vascular embolism balloon catheter pressure application system, including a processor 100, the output end of the processor 100 is connected to an initial setting module 200, a pressure monitoring and acquisition module 300, a pressure analysis module 400, a feedback adjustment module 500 and a data processing module 600. The initial setting module 200 is used by a doctor to input a preset pressure parameter range and treatment parameters through an operation interface according to the patient's vascular condition and treatment needs. The pressure monitoring and acquisition module 300 is used to monitor the pressure changes in the balloon in real time during the vascular embolization surgery and convert the collected pressure signal into an electrical signal and output it to the processor 100;

[0039] After receiving the pressure signal, the processor 100 controls the pressure analysis module 400 to run the pressure signal acquisition and processing program, performs pre-processing operations such as filtering, amplification, and calibration on the signal to obtain an accurate pressure value. Then, the pressure analysis and judgment program is run to compare the real-time pressure value with the preset pressure parameter range. If the pressure is within the normal range, monitoring continues. If the pressure exceeds the normal range, a signal is sent to the feedback adjustment module 500.

[0040] The feedback regulation module 500 generates corresponding feedback regulation control instructions based on the pressure analysis results. If the pressure is too high, the control instruction will be sent to the gas exhaust device of the actuator to open the exhaust valve, slowly release the gas in the balloon, and reduce the pressure. If the pressure is too low, the control instruction will be sent to the gas injection device to start the air pump and inject an appropriate amount of gas into the balloon to increase the pressure. After receiving the control instruction, the actuator performs corresponding actions according to the instruction requirements to adjust the pressure in the balloon. The pressure monitoring and acquisition module 300 continues to monitor the pressure changes in real time and feeds back the new pressure signal to the processor 100, forming a closed-loop feedback regulation process. The data processing module 600 is used to perform the final data processing and recording, and save the pressure monitoring data of the pressure monitoring and acquisition module 300 and the feedback regulation records of the feedback regulation module 500 during this treatment process for subsequent query and analysis.

[0041] When the system is in use, in the initial setting stage, the doctor inputs the preset pressure parameter range and treatment parameters through the initial setting module 200 according to the patient's vascular condition and treatment needs, and monitors the pressure changes in the balloon in real time during the vascular embolization surgery through the pressure monitoring and acquisition module 300, and converts the collected pressure signal into an electrical signal and outputs it to the processor 100. After receiving the pressure signal, the processor 100 controls the pressure analysis module 400 to run the pressure signal acquisition and processing program, performs pre-processing operations such as filtering, amplification, and calibration on the signal to obtain an accurate pressure value, and then runs the pressure analysis and judgment program to compare the real-time pressure value with the preset pressure parameter range. If the pressure is within the normal range, monitoring continues. If the pressure exceeds the normal range, a signal is sent to the feedback adjustment module 500, and the feedback adjustment module 500 Based on the pressure analysis results, corresponding feedback control instructions are generated. If the pressure is too high, the control instruction is sent to the gas exhaust device of the actuator, opening the exhaust valve and slowly releasing the gas in the balloon to reduce the pressure. If the pressure is too low, the control instruction is sent to the gas injection device, starting the air pump and injecting an appropriate amount of gas into the balloon to increase the pressure. After receiving the control instruction, the actuator performs the corresponding action according to the instruction to adjust the pressure in the balloon. The pressure monitoring and acquisition module 300 continues to monitor the pressure changes in real time and feeds the new pressure signal back to the processor 100, forming a closed-loop feedback control process. The data processing module 600 is responsible for final data processing and recording, saving the pressure monitoring data of the pressure monitoring and acquisition module 300 and the feedback adjustment records of the feedback adjustment module 500 during the treatment process for subsequent query and analysis. Real-time monitoring and feedback adjustment improve the accuracy and effectiveness of vascular embolization surgery. The doctor enters the preset pressure parameters during the initial setup phase. The system automatically monitors and adjusts the pressure in the balloon during the procedure, ensuring the safety and stability of the treatment process. The automated closed-loop feedback mechanism reduces human error and enhances patient safety. The final data processing and recording functions provide valuable reference for subsequent analysis and improvement.
