In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.
[0034] Combine the following Figures 1 to 9 , a uterine abnormal bleeding steam ablation balloon inflation, deflation and detection device provided by an embodiment of the present invention is described in detail through specific embodiments and application scenarios.
[0035] In the embodiments of the invention, reference is made to Figures 1 to 7 A uterine abnormal bleeding steam ablation balloon inflation and deflation and detection device 10 comprises a handle mechanism 100, a guide rod 200, an airbag structure 300 and an air supply system 400. The guide rod 200 is arranged at the front end of the handle mechanism 100. A plurality of cavities 210 are arranged in the guide rod 200. A plurality of air outlet holes 220 are arranged on the outer peripheral wall of the guide rod 200. The plurality of air outlet holes 220 are connected to the plurality of cavities 210 in a one-to-one correspondence. The airbag structure 300 is sheathed on the guide rod 200. The bag structure 300 includes a plurality of independent air bags 310, and the plurality of air bags 310 are connected to the air outlet holes 220 in a one-to-one correspondence; the air supply system 400 includes a plurality of air paths 410, an air supply mechanism 420 and a negative pressure mechanism 430, and the plurality of air paths 410 are connected to the plurality of lumens 210 in a one-to-one correspondence. The air supply mechanism 420 is used to supply air to the air bags 310 respectively through the air paths 410, and the negative pressure mechanism 430 is used to exhaust the air bags 310 or provide a negative pressure environment respectively through the air paths 410.
[0036] The handle mechanism 100 is the operation center of the entire device, through which the doctor controls and operates the entire balloon inflation and deflation and detection device. The handle is ergonomically designed to ensure that the doctor feels comfortable and convenient during the operation.
[0037] The handle mechanism 100 provides a gripping point to facilitate the doctor's operation during the operation. Among them, various control buttons or knobs can be integrated on the handle mechanism 100 to start, stop and adjust the inflation and deflation process of the airbag 310.
[0038] The guide rod 200 serves as a bridge connecting the handle and the airbag structure 300 and provides physical support. The guide rod 200 also has multiple lumens 210 built in, and the lumens 210 are used to transmit gas to each airbag 310.
[0039] Each lumen 210 corresponds to an airbag 310 , ensuring that gas can be independently delivered to each airbag 310 , thereby achieving individual control of each airbag 310 .
[0040] The gas outlet holes 220 correspond to the lumens 210 one by one, so that the gas can accurately enter the corresponding airbag 310, ensuring that the expansion state of each airbag 310 is consistent and controllable.
[0041] The guide rod 200 is provided with a plurality of air outlet holes 220 to allow the use of different numbers of air bags 310, thereby improving the flexibility and applicability of the device.
[0042] The airbag structure 300 is the part that directly contacts the inner wall of the uterus, and is responsible for forming a sealed environment and bearing the steam pressure. The multiple airbags can be a conjoined structure or relatively independent and fixed by means of adhesive or the like.
[0043] Each airbag 310 is designed to have a specific shape (such as a cylindrical shape, an ellipsoid shape, or a quasi-ellipsoid shape, etc.) to better fit the anatomical structure of the cervical canal and enhance the sealing effect.
[0044] The airbags 310 are connected to the air outlet holes 220 one by one, ensuring that each airbag 310 can obtain gas supply from the lumen 210 of the guide rod 200, achieving precise control. It can also be selectively inflated and deflated as needed to improve the pertinence and effectiveness of treatment.
[0045] The gas supply system 400 is responsible for providing, regulating and monitoring the gas pressure in the airbag 310 .
[0046] Each gas path 410 corresponds to an airbag 310 , ensuring that gas can be independently delivered to each airbag 310 , thereby achieving individual control of each airbag 310 .
[0047] The gas supply mechanism 420 includes components such as an air pump, an air storage tank 423, and a pressure regulating valve, which are used to generate and adjust the gas pressure to ensure that each airbag 310 can reach an optimal expansion state.
[0048] The negative pressure mechanism 430 is used to exhaust air or provide a negative pressure environment, so that the airbag 310 is quickly flattened and close to the guide rod 200 after the treatment is completed, which is convenient for safe removal and reduces the risk of secondary injury. At the same time, each air path 410 can be deflated separately, which is relatively flexible. If necessary, the distal airbag 310 can be deflated separately to continue the treatment of the part blocked by it.
[0049] In some embodiments, the pressure of each airbag 310 can also be monitored in real time through a pressure sensor and a control system, and adjustments can be made when necessary to maintain a stable air pressure and prevent leakage.
[0050] The present application designs each airbag 310 in the airbag structure 300 into a specific shape (such as an ellipsoid), so that it can better adapt to the anatomical structure of the cervical canal after inflation. It ensures that the airbag 310 fits tightly with the cervical canal, thereby forming an effective sealing environment. The multiple air paths 410 in the air supply system 400 are connected to the multiple cavities 210 in the guide rod 200 in a one-to-one correspondence, and each airbag 310 can be controlled by an independent air path 410. It is possible to adjust the air pressure for each airbag 310 separately, ensuring that all airbags 310 can reach the optimal expansion state and improve the overall sealing effect. Through the air supply mechanism 420 and the negative pressure mechanism 430, the pressure of each airbag 310 is monitored in real time and adjusted when necessary. It helps to maintain a stable air pressure and prevent leakage caused by pressure fluctuations.
[0051] After the treatment is completed, the airbag 310 is vented and negative pressure is applied through the negative pressure mechanism 430. The negative pressure mechanism 430 can quickly exhaust or evacuate the gas in the airbag 310, so that the airbag 310 is flattened and tightly attached to the guide rod 200. Among them, the air circuit 410 of each airbag 310 can be independently controlled, and each airbag 310 can be deflated and negatively pressurized separately. To ensure that all airbags 310 are in a flat state, reduce the volume, and facilitate safe removal. The flattened airbag 310 reduces the contact area with the surrounding tissues and reduces the risk of scratching or compressing sensitive parts such as the cervical canal during the removal process. Thereby improving the safety and reliability of the entire treatment process. At the same time, one of the airbags 310 can be inflated and deflated according to treatment needs to improve the adaptability of the device.
[0052] Reference Figures 1 to 3 According to a uterine abnormal bleeding steam ablation balloon inflation, deflation and detection device 10 provided by the present invention, multiple airbags 310 are respectively arranged in a cylindrical structure, and smooth guide surfaces are formed at both ends of the airbags 310. The long radius of the multiple airbags 310 is arranged to decrease in sequence in the direction away from the handle mechanism 100.
[0053] It is understandable that the columnar structure may include cylindrical, ellipsoidal, and ellipsoidal shapes. In gynecological surgery, the shape and size of the uterus vary from individual to individual. The airbag 310 in the shape of a columnar structure can better fit the contour of the uterus, provide uniform and effective compression, and thus more effectively control bleeding. At the same time, the columnar structure shape also allows the airbag 310 to more easily adapt to the shape of the uterus during inflation and deflation, reducing potential damage to uterine tissue.
[0054] The long radius of each airbag 310 gradually decreases from the airbag 310 close to the handle mechanism 100 to the airbag 310 far from the handle mechanism 100. In this way, as the airbags 310 extend distally, their gradually decreasing size can better adapt to the gradually shrinking or tapered structure of the uterus, ensuring that the entire uterus can be evenly and effectively compressed.
[0055] Reference Figures 1 to 5 According to the present invention, a uterine abnormal bleeding steam ablation balloon inflation, deflation and detection device 10 also includes a turntable mechanism 500, which is arranged between the guide rod 200 and the air path 410. The turntable mechanism 500 includes a sealing member 510, which is sealed and abutted between the guide rod 200 and the air path 410.
[0056] It is understandable that the turntable mechanism 500 is used to realize the connection state and relative position between the guide rod 200 and the gas circuit 410. During the inflation and deflation process, the guide rod 200 is responsible for transmitting the operation instructions or physical connection, while the gas circuit 410 is responsible for the circulation of gas. The turntable mechanism 500 serves as an intermediate connection mechanism to ensure the effective communication between the gas circuit 410 and the cavity tube 210, so that the gas can flow to the designated airbag 310 as needed.
[0057] During steam ablation treatment of the inner wall of the uterus, the steam needs to be sealed to prevent steam leakage from burning other healthy tissues such as the vagina and cervical canal. The seal 510 is located in the turntable mechanism 500, and the seal abuts between the guide rod 200 and the air path 410 to prevent gas or liquid from leaking from the gap between the two.
[0058] Reference Figures 2 to 5 According to a uterine abnormal bleeding steam ablation balloon inflation, deflation and detection device 10 provided by the present invention, the turntable mechanism 500 also includes a turntable bottom cover 520, a turntable upper cover 530 and a plurality of air needle steel tubes 540. A connecting boss 521 is formed on the side of the turntable bottom cover 520 facing the guide rod 200, and a sealing member 510 is disposed in the connecting boss 521. The turntable bottom cover 520 is connected to the guide rod 200 through the connecting boss 521. The turntable upper cover 530 covers the side of the turntable bottom cover 520 away from the guide rod 200. A plurality of air needle steel tubes 540 are penetrated on the turntable upper cover 530. One end of the air needle steel tube 540 is connected to the cavity tube 210, and the other end is coupled and connected to the air path 410.
[0059] It is understandable that the connecting boss 521 formed on the side of the turntable bottom cover 520 facing the guide rod 200 is the connection point between the turntable mechanism 500 and the guide rod 200. Ensure that the turntable mechanism 500 can be stably fixed on the device while allowing it to rotate or adjust as necessary. The seal 510 is provided inside the connecting boss 521, and the seal 510 fits tightly between the end surface of the guide rod 200 and the turntable chassis, ensuring that the flow direction of the gas is controllable and will not leak. The turntable upper cover 530 covers the side of the turntable bottom cover 520 away from the guide rod 200, forming a closed space. A plurality of gas needle steel tubes 540 are pierced on the turntable upper cover 530, and the steel tube is a channel connecting the cavity tube 210 and the gas path 410. One end of the gas needle steel tube 540 is connected to the cavity tube 210, and the other end is coupled and connected to the gas path 410. This ensures that the gas can flow from one gas path 410 to another gas path 410 as needed, thereby achieving inflation and deflation control of the airbag 310 .
[0060] Reference Figure 6 According to the present invention, a uterine abnormal bleeding steam ablation balloon inflation, deflation and detection device 10 also includes a control card 600, and the control card 600 is signal-connected to the air supply system 400.
[0061] It is understood that the control card 600 is connected to the gas supply system 400 through signal communication, and can automatically control the operation of the gas supply system 400, such as inflation, deflation, and pressure regulation. The control card 600 can accurately control the pressure and flow output of the gas supply system 400 according to a preset program or real-time monitoring data. For example, the control card 600 can automatically adjust the pressure in the balloon according to the real-time data provided by the detection system to achieve the best hemostatic effect or diagnostic accuracy.
[0062] Reference Figure 6 According to a uterine abnormal bleeding steam ablation balloon inflation, deflation and detection device 10 provided by the present invention, the gas supply mechanism 420 includes a gas source 421, a filter 422 and a gas storage tank 423, the filter 422 is connected between the gas source 421 and the gas storage tank 423, the gas storage tank 423 is respectively connected to multiple gas paths 410, and the gas source 421 is connected to the control card 600 signal.
[0063] It is understandable that the gas source 421 provides a source of gas, which may be compressed air, inert gas or other gas suitable for medical use. It is the power source of the entire gas supply system 400.
[0064] The filter 422 is connected between the gas source 421 and the gas tank 423, and its function is to filter out impurities (such as dust, moisture, oil mist, etc.) in the gas to ensure the purity of the gas entering the gas tank 423 and the subsequent gas path 410. Because any impurities may cause unnecessary risks to the patient or affect the performance of the equipment.
[0065] The gas storage tank 423 is used to store filtered gas so that it can be quickly and stably supplied to the balloon when needed. The gas storage tank 423 also plays a buffering role, which can balance the fluctuation of the output of the gas source 421 and ensure the stability of the gas supply.
[0066] In this embodiment, the control card 600 realizes automatic control of the gas source 421. The control card 600 can accurately control parameters such as the flow rate, pressure, and filling and discharging time of the gas, thereby improving the intelligence level of the entire device.
[0067] Reference Figure 6 According to a uterine abnormal bleeding steam ablation balloon inflation, deflation and detection device 10 provided by the present invention, the air circuit 410 includes an air supply circuit 411 and a negative pressure circuit 412, the air supply circuit 411 is connected between the airbag 310 and the air supply mechanism 420, and the negative pressure circuit 412 is connected between the negative pressure mechanism 430 and the airbag 310.
[0068] It is understood that the air supply circuit 411 is connected between the airbag 310 and the air supply mechanism 420. When necessary, the air supply mechanism 420 provides air to the airbag 310 through the air supply circuit 411 to expand the airbag 310 to a predetermined size and pressure. The air supply circuit 411 may include components such as a flow control valve and a pressure sensor to ensure that the gas enters the airbag 310 at a predetermined flow rate and pressure.
[0069] The negative pressure circuit 412 is connected between the airbag 310 and the negative pressure mechanism 430. When necessary, the negative pressure mechanism 430 extracts gas from the airbag 310 through the negative pressure circuit 412 to shrink it. This is used to adjust the pressure of the airbag 310, release the pressure on the uterine wall, or completely exhaust the airbag 310 after the treatment. The negative pressure circuit 412 may include components such as a negative pressure pump, a pressure sensor, and a flow control valve to accurately control the size and duration of the negative pressure.
[0070] Reference Figure 6 and Figure 8 According to a uterine abnormal bleeding steam ablation balloon inflation, deflation and detection device 10 provided by the present invention, the air supply circuit 411 is provided with an air supply on-off valve 440, an air supply pressure regulating valve 450 and an air supply check valve 460 in sequence in the direction from the air supply mechanism 420 toward the airbag 310. The air supply on-off valve 440, the air supply pressure regulating valve 450 and the air supply check valve 460 are all connected to the control card 600 signal.
[0071] It is understandable that the air supply on-off valve 440 is located at the front end of the air supply circuit 411 and is responsible for controlling the on-off of the gas. It is opened or closed according to the instruction of the control card 600 to determine whether to supply gas to the airbag 310. The air supply on-off valve 440 is connected through the signal of the control card 600, and the air supply on-off valve 440 can achieve precise on-off control to ensure that the gas is only supplied when needed. When the air supply is not needed, the air supply on-off valve 440 can completely cut off the gas source 421 to avoid accidental inflation, thereby improving the safety of operation.
[0072] The air supply pressure regulating valve 450 is located after the air supply on-off valve 440 and is responsible for regulating the air supply pressure. The high-pressure gas provided by the air supply mechanism 420 is adjusted to a pressure range suitable for the inflation of the airbag 310. The air supply pressure regulating valve 450 is connected through the signal of the control card 600. The air supply pressure regulating valve 450 can automatically adjust the output pressure according to the preset parameters or real-time monitoring data to ensure that each airbag 310 can obtain the appropriate inflation pressure. Different patients may require different inflation pressures. The air supply pressure regulating valve 450 can be flexibly adjusted according to the specific situation to optimize the treatment effect.
[0073] The gas supply check valve 460 is located after the gas supply pressure regulating valve 450 to ensure that the gas can only flow in one direction, that is, from the gas supply mechanism 420 to the airbag 310, but not in the opposite direction. During the inflation process, the check valve can prevent the gas from flowing back from the airbag 310 to the gas supply system 400, ensuring the stability of the pressure in the airbag 310. During deflation or other operations, the gas supply check valve 460 can prevent the gas from flowing back, avoiding unnecessary risks and ensuring the safety of the operation.
[0074] The air supply on-off valve 440, the air supply pressure regulating valve 450 and the air supply check valve 460 are all connected to the control card 600 signal, so that the control card 600 can directly control these valves through electrical signals, thereby realizing automatic control of the entire air supply circuit 411, reducing the need for manual operation and improving the accuracy and efficiency of operation.
[0075] Reference Figure 6 and Fig. 9 According to a uterine abnormal bleeding steam ablation balloon inflation, deflation and detection device 10 provided by the present invention, a negative pressure circuit 412 is provided with a negative pressure on-off valve 470 and a three-way valve 480 in sequence in the direction from the negative pressure mechanism 430 toward the airbag 310, and the negative pressure on-off valve 470 and the three-way valve 480 are both connected to the control card 600 signal, wherein the inlet of the three-way valve 480 is connected to the outlet of the negative pressure on-off valve 470, the first outlet of the three-way valve 480 is connected to the external environment, and the second outlet of the three-way valve 480 is connected to the negative pressure mechanism 430.
[0076] It is understandable that the main function of the negative pressure on-off valve 470 is to control the opening and closing of the negative pressure circuit 412. When the control card 600 sends an opening signal, the negative pressure on-off valve 470 opens, allowing the negative pressure mechanism 430 to extract or discharge gas from the airbag 310 through the negative pressure circuit 412; when the control card 600 sends a closing signal, the negative pressure on-off valve 470 closes, cutting off the negative pressure circuit 412, and preventing external air or gas from the negative pressure mechanism 430 from entering the airbag 310.
[0077] The three-way valve 480 is a valve with three connection ports, allowing the gas to switch between two different paths. In the negative pressure circuit 412 of the present invention, the inlet of the three-way valve 480 is connected to the outlet of the negative pressure on-off valve 470, the first outlet is connected to the external environment, and the second outlet is connected to the negative pressure mechanism 430. When the three-way valve 480 is switched to this path, the gas in the airbag 310 is allowed to be released into the external environment through the negative pressure circuit 412. It is mainly used to discharge the gas in the airbag 310 after the treatment or detection is completed.
[0078] When the three-way valve 480 is switched to this path, the negative pressure mechanism 430 is allowed to extract gas from the airbag 310 through the negative pressure circuit 412 to achieve negative pressure deflation. This helps to adjust the pressure of the airbag 310, or quickly release the gas in the airbag 310 when necessary, so that the airbag 310 is flat on the guide rod 200, avoiding the patient's pain when the treatment handle is withdrawn.
[0079] Reference Figure 6 According to the device 10 for inflation, deflation and detection of steam ablation balloon for abnormal uterine bleeding provided by the present invention, the air supply system 400 also includes a first pressure gauge 424, which is arranged at the front end of the air supply mechanism 420, and the first pressure gauge 424 is used to detect the air pressure value of the air supply mechanism 420.
[0080] It is understandable that the first pressure gauge 424 is installed at the front end of the gas supply mechanism 420, and can directly measure and display the air pressure value provided by the gas supply mechanism 420. The air pressure value of the gas supply mechanism 420 is detected by the first pressure gauge 424, and the first pressure gauge 424 helps to ensure the stability of the air pressure. The first pressure gauge 424 is connected to the control card 600 by signal, and the control card 600 can adjust the air supply rate of the gas source 421 in real time according to the pressure value of the first pressure gauge 424 to ensure the stability of the air pressure of the gas supply.
[0081] Reference Figure 6 and Figure 8According to a uterine abnormal bleeding steam ablation balloon inflation, deflation and detection device 10 provided by the present invention, the air supply system 400 also includes a plurality of second pressure gauges 490, and the plurality of second pressure gauges 490 are respectively arranged on a plurality of air paths 410, and are located at the front end of the air supply circuit 411 and the negative pressure circuit 412, and the second pressure gauge 490 is used to detect the air pressure value of the airbag 310.
[0082] It is understandable that the second pressure gauge 490 is used to detect the air pressure value of the corresponding airbag 310 on each air path 410, detect whether the airbag 310 is leaking, and also detect whether the air pressure of each airbag 310 is too high. If the air pressure value of the airbag 310 is too high, an alarm is issued to remind the medical staff. The second pressure gauge 490 is connected to the control card 600 signal to feed back the air pressure value of each airbag 310 to the control card 600, and then the control card 600 controls the air supply mechanism 420 or the negative pressure mechanism 430 to work according to relevant instructions or preset programs.
