[0029] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0030] like Figures 1 to 3 As shown, a first aspect of this utility model provides an intracavitary medical auxiliary device, comprising:

[0031] Guide rod 100;

[0032] The first balloon 102 includes at least two first split balloons 104;

[0033] The second balloon 106 is disposed adjacent to the first balloon 102 along the axial direction of the guide rod 100, and the second balloon 106 includes at least two second split balloons 108.

[0034] The gas filling component 110 is in fluid communication with the first balloon 102 and the second balloon 106;

[0035] Control element 112 is disposed on guide rod 100. Control element 112 is used to control the fluid flow between gas filling element 110 and first split bladder 104 and / or second split bladder 108.

[0036] According to the first aspect of the present invention, the intracavitary medical auxiliary device allows for independent control of the first split balloon 104 and the second split balloon 108 via the control element 112. This enables the surgeon to precisely adjust the inflation degree and position of the balloons according to surgical needs, thereby improving the precision and controllability of the surgery. Since both the first balloon 102 and the second balloon 106 contain at least two split balloons, which can inflate or deflate independently, the device can adapt to target areas of different shapes and sizes, enhancing its adaptability and flexibility. Through precise inflation control and a highly adaptable design, the surgeon can more effectively control pressure and support during the surgical process, thereby reducing surgical risks and improving patient outcomes. Due to the device's precise control and adaptability, the surgeon can complete the surgical procedure more quickly, simplifying the surgical process and reducing surgical time.

[0037] Please continue reading Figures 1 to 3 The first aspect of this utility model relates to an intracavitary medical assistive device designed to provide assistance during medical surgery or treatment. The intracavitary medical assistive device mainly comprises five parts: a guide rod 100, a first balloon 102, a second balloon 106, an inflator 110, and a control unit 112.

[0038] The guide rod 100 serves as the support and guiding structure for the entire device, ensuring that the device can accurately and stably enter the target area within the patient's body. The length, diameter, and material of the guide rod 100 can be selected according to specific medical needs to ensure its safety and effectiveness during operation.

[0039] The first balloon 102 is an inflatable structure used to provide pressure or support within a target area. The first balloon 102 is designed to contain at least two first split balloons 104, which can inflate or deflate independently, thereby allowing for finer control and adaptability.

[0040] Similar to the first balloon 102, the second balloon 106 is also inflatable and is disposed adjacent to the first balloon 102 along the axial direction of the guide rod 100. The second balloon 106 also includes at least two second split balloons 108, which are also capable of independent inflation or deflation.

[0041] The gas filling component 110 is a fluid control assembly for supplying gas or liquid to the first balloon 102 and the second balloon 106 to inflate them. The gas filling component 110 is in fluid communication with the first balloon 102 and the second balloon 106 to ensure that gas or liquid can smoothly enter the balloons.

[0042] The control element 112 is mounted on the guide rod 100, and its main function is to control the fluid flow between the gas filling element 110 and the first split capsule 104 and / or the second split capsule 108. Through the control element 112, the doctor can precisely control which split capsules should inflate and the degree of inflation, thereby achieving precise operation of the entire device.

[0043] According to one embodiment of the present invention, there are at least three first split capsules 104, and the spacing between the at least three first split capsules 104 is equal.

[0044] There are at least three second sub-sacs 108, and the spacing between the at least three second sub-sacs 108 is equal.

[0045] In one embodiment of this utility model, the design of the first balloon 102 and the second balloon 106 has been further optimized.

[0046] The first balloon 102 comprises at least three first segmental balloons 104, and the spacing between these first segmental balloons 104 is equal. This design ensures that the first balloon 102 provides uniform support when inflated, avoiding potential risks caused by excessively high or low local pressure.

[0047] Similar to the first balloon 102, the second balloon 106 also contains at least three second balloons 108, and the spacing between these second balloons 108 is equally equal. This design allows the second balloon 106 to provide uniform support during inflation, further enhancing the adaptability and safety of the device.

[0048] By ensuring equal spacing between the first split balloon 104 and the second split balloon 108, the balloon can provide more uniform support during inflation. This helps reduce the risk of tissue damage due to excessive local pressure, while improving the precision and safety of the procedure. Since each split balloon can inflate or deflate independently, and their spacing is equal, the surgeon can more easily predict and control the overall inflation effect of the balloon. This helps the surgeon make more accurate decisions during the procedure, further improving the controllability of the surgery. By providing uniform and controllable support, the endovascular medical aid device of this embodiment can better adapt to target areas of different shapes and sizes. This helps the surgeon achieve more precise positioning and support during the procedure, thereby optimizing surgical outcomes and improving patient prognosis.

[0049] According to one embodiment of the present invention, two adjacent first split capsules 104 are independent of each other, and two adjacent second split capsules 108 are independent of each other.

[0050] In one embodiment of this invention, two adjacent first split capsules 104 are independent of each other, meaning there is no direct fluid connection between them. Each first split capsule 104 can independently receive gas or liquid from the gas filling member 110, thereby expanding or contracting independently.

[0051] Similar to the first split capsule 104, the two adjacent second split capsules 108 are also independent of each other. This design ensures that each second split capsule 108 can be independently expanded or contracted according to surgical needs.

[0052] Because each individual balloon is independent, surgeons can selectively inflate or deflate specific balloons according to surgical needs. This flexibility allows surgeons to more precisely control the overall shape and support of the balloon, adapting it to target areas of different shapes and sizes. The independent balloon design helps reduce the risk of tissue damage due to excessive local pressure. Surgeons can precisely control the expansion of each balloon to avoid overcompression, thus protecting the safety of surrounding tissues. The independent balloons enable surgeons to achieve more precise positioning and support during surgery. This helps reduce surgical time and complexity, while improving surgical success rates and patient satisfaction. Since each balloon is independent, if one balloon malfunctions or is damaged, surgeons can more easily repair or replace it without replacing the entire balloon structure. This reduces maintenance costs and improves the reliability and durability of the device.

[0053] According to one embodiment of the present invention, the guide rod 100 is provided with an air passage inside, and the guide rod 100 is provided with a first air hole that corresponds one-to-one with the first split bladder 104 and is in fluid communication with the air passage. The guide rod 100 is also provided with a second air hole that corresponds one-to-one with the second split bladder 108 and is in fluid communication with the air passage.

[0054] In one embodiment of this invention, the guide rod 100 has an internal ventilation channel, which is a continuous fluid channel for transferring gas or liquid from the gas filling component 110 to each individual capsule. The design of the ventilation channel ensures that the gas or liquid can flow smoothly and quickly reach each individual capsule when needed.

[0055] On the guide rod 100, a first vent hole is provided at a position corresponding to each first split capsule 104. These first vent holes are in fluid communication with the venting channel, allowing gas or liquid to flow from the venting channel into the corresponding first split capsule 104, thereby causing it to expand.

[0056] Similarly, a second vent is also provided on the guide rod 100 at a position corresponding to each second split capsule 108. These second vents are also in fluid communication with the venting channel to ensure that gas or liquid can flow into the corresponding second split capsule 108 to achieve its expansion.

[0057] By setting up airways and connecting them with first and second vents, it is possible to ensure that gas or liquid can be rapidly and accurately delivered to each individual balloon. This improves the efficiency of fluid delivery and ensures that the balloon's inflation rate and degree match the surgical requirements. Since each individual balloon is connected to the airway via an independent vent, the surgeon can precisely adjust the inflation degree of each balloon by controlling the inflation device 110. This precise control enhances the controllability of the surgery, allowing the surgeon to more accurately position and adjust the balloon's shape and support. By precisely controlling the inflation of each individual balloon, the surgeon can better adapt to target areas of different shapes and sizes, thereby achieving more precise surgical results. This helps reduce surgical time and complexity, while improving the success rate and patient satisfaction. Due to the airway setup and the one-to-one correspondence between the vents and the individual balloons, the surgeon can more easily monitor and control the balloon's inflation status. This simplifies the surgical procedure and reduces surgical difficulty and risk.

[0058] According to one embodiment of the present invention, the gas filling component 110 includes a first gas source and a second gas source, the first gas source being in fluid communication with the first split bladder 104, and the second gas source being in fluid communication with the second split bladder 108.

[0059] In one embodiment of the present invention, the gas filling component 110 includes two independent gas sources: a first gas source and a second gas source.

[0060] The first gas source is in fluid communication with the first split capsule 104. This means that the first gas source can independently supply gas to the first split capsule 104 without relying on the gas supply of other split capsules. This design ensures that the expansion and contraction of the first split capsule 104 can be controlled independently of the other split capsules.

[0061] Similar to the first gas source, the second gas source is in fluid communication with the second split capsule 108. It is responsible for providing an independent gas supply to the second split capsule 108. This design allows the expansion and contraction of the second split capsule 108 to be controlled independently, without being affected by the state of other split capsules.

[0062] With this design, the gas filling unit 110 can provide independent and precise gas control for different split capsules, thereby improving the flexibility and controllability of intracavitary medical aids.

[0063] Because the first and second gas sources can independently supply gas to the first and second segmental balloons 104 and 108, surgeons can precisely control the expansion and contraction of each segmental balloon. This precise control helps surgeons more accurately position and adjust the shape and support of the balloons during surgery. The independent gas source design reduces the risk of a problem in one segmental balloon affecting the others. If one segmental balloon leaks or malfunctions, the others can still maintain normal gas supply and expansion, ensuring the safety and reliability of the surgery. By independently controlling the expansion of each segmental balloon, surgeons can better adapt to target areas of different shapes and sizes. This helps achieve more precise surgical results, reduces surgical time and complexity, and improves surgical success rates and patient satisfaction. The independent gas source design makes it easier for surgeons to monitor and control the expansion status of each segmental balloon. This simplifies the surgical procedure, reduces surgical difficulty and risk, and improves surgical efficiency.

[0064] According to one embodiment of the present invention, the control component 112 includes a first valve group and a second valve group. The first valve group is connected between the first air source and the first split bladder 104, and the second valve group is connected between the second air source and the second split bladder 108.

[0065] In one embodiment of the present invention, the control element 112 includes two independent valve groups: a first valve group and a second valve group.

[0066] The first valve assembly is connected between the first gas source and the first split-cell sac 104. Its main function is to control the gas flow between the first gas source and the first split-cell sac 104. By operating the first valve assembly, the doctor can precisely adjust the gas supply to the first split-cell sac 104, thereby controlling its expansion and contraction.

[0067] Similar to the first valve assembly, the second valve assembly is connected between the second gas source and the second split capsule 108. It also controls the gas flow between the second gas source and the second split capsule 108. By operating the second valve assembly, the doctor can independently adjust the gas supply to the second split capsule 108, achieving precise control over its expansion and contraction.

[0068] This design allows doctors to control the gas supply to the first split capsule 104 and the second split capsule 108 separately without worrying about them interfering with each other. This greatly improves the flexibility and controllability of intracavitary medical aids.

[0069] By independently controlling the first and second valve groups, the surgeon can precisely regulate the gas supply to the first split balloon 104 and the second split balloon 108. This precise control helps the surgeon more accurately position and adjust the shape and support of the balloons during surgery, thereby improving surgical accuracy. Independently controlling the gas supply to the first split balloon 104 and the second split balloon 108 reduces the risk of a problem in one split balloon affecting the entire device. If a split balloon leaks or malfunctions, the surgeon can quickly shut off the corresponding valve group to prevent the problem from spreading, thus ensuring the safety and reliability of the surgery. By independently controlling the expansion of each split balloon, the surgeon can better adapt to target areas of different shapes and sizes. This helps achieve more precise surgical results, reduces surgical time and complexity, and improves surgical success rates and patient satisfaction. Although the number of valve groups increases, each valve group is independently controlled, making it easier for the surgeon to monitor and control the expansion status of each split balloon. Overall, this effectively simplifies the surgical procedure and reduces surgical difficulty and risk.

[0070] According to one embodiment of the present invention, a first identifier corresponding to the first split bladder 104 is provided on the first valve group, and a second identifier corresponding to the second split bladder 108 is provided on the second valve group.

[0071] In one embodiment of this utility model, the first valve group and the second valve group are respectively provided with markers corresponding to the first split bladder 104 and the second split bladder 108.

[0072] On the first valve assembly, a first identifier is provided at a position corresponding to each first split capsule 104. These identifiers can be color markings, numerical codes, letter identifiers, or any other symbols that can clearly distinguish each split capsule. Their main function is to help doctors quickly identify and locate the first valve assembly section connected to a specific first split capsule 104.

[0073] Similar to the first valve assembly, a second marker is also provided on the second valve assembly at a position corresponding to each second split capsule 108. These second markers are also used to help doctors quickly identify and locate the second valve assembly section connected to a specific second split capsule 108.

[0074] By setting these markers, doctors can more easily identify and differentiate different valve assembly sections, thereby controlling the gas supply to each individual capsule more accurately.

[0075] The placement of markers allows surgeons to more quickly identify and locate the valve assembly connected to a specific capsule. This significantly simplifies the procedure, reduces its complexity, and improves surgical efficiency. By clearly distinguishing each valve assembly, surgeons can ensure accurate control of the gas supply to each capsule during the procedure. This helps avoid misoperation and improves surgical precision and safety.

[0076] According to one embodiment of the present invention, the end of the guide rod 100 away from the control member 112 is provided with an arc-shaped head 114.

[0077] In one embodiment of this invention, an arc-shaped head 114 is positioned at the end of the guide rod 100 away from the control member 112. This arc-shaped design not only gives the guide rod 100 a smoother profile but also enhances its adaptability and flexibility in complex anatomical structures. The arc-shaped head 114 can more easily conform to the natural curvature of blood vessels, cavities, or other biological tissues, thereby reducing the risk of tissue damage during insertion or movement of the device.

[0078] Furthermore, the design of the curved head 114 may also take into account fluid dynamics principles to reduce resistance encountered during insertion, allowing the device to enter the target area more smoothly. Simultaneously, the curved head 114 may also possess a guiding function, helping the surgeon to more accurately position the device, improving the precision and efficiency of the surgery.

[0079] The curved head 114 design allows the guide rod 100 to better adapt to complex tissue conditions, reducing the risk of tissue damage during device insertion. The curved head 114 reduces resistance during insertion, allowing the device to enter the target area more smoothly and improving surgical efficiency.

[0080] According to one embodiment of the present invention, a flexible connecting pipe 116 is provided between the guide rod 100 and the gas filling component 110.

[0081] In one embodiment of this invention, the flexible connecting pipe 116 is a pipe capable of bending and twisting, typically made of rubber, plastic, or other elastic materials. In this embodiment, one end of the flexible connecting pipe 116 is connected to the guide rod 100, and the other end is connected to the gas filling component 110. This connection method allows for a certain degree of relative movement between the guide rod 100 and the gas filling component 110, thereby improving the flexibility and adaptability of the entire device.

[0082] The design of the flexible connecting tube 116 also takes into account the needs of fluid transmission. It has one or more fluid channels inside to ensure that gas or liquid can be smoothly transmitted from the gas filling unit 110 to the guide rod 100, and further to the individual compartments. These fluid channels remain unobstructed when the flexible connecting tube 116 is bent or twisted, thereby ensuring the stability and reliability of fluid transmission.

[0083] The flexible connecting tube 116 allows for a certain degree of relative movement between the guide rod 100 and the gas supply unit 110, enabling the entire device to adapt more flexibly to complex anatomical structures during insertion or movement. This reduces the risk of tissue damage and improves surgical precision and safety. Due to the presence of the flexible connecting tube 116, the connection between the guide rod 100 and the gas supply unit 110 is no longer limited to a fixed direction and angle. This allows the device to more easily adapt to different surgical environments and operational needs, thereby improving surgical efficiency and success rates.

[0084] A second aspect of this utility model provides an intracavitary medical device, including the intracavitary medical auxiliary device as described above.

[0085] A second aspect of this utility model provides an intracavitary medical device that integrates the previously described intracavitary medical auxiliary device. The intracavitary medical auxiliary device, as the core component of this device, includes key elements such as a gas supply component 110, a control component 112, a guide rod 100, and a flexible connecting tube 116 between them. These elements work together to give the intracavitary medical device excellent flexibility, precision, and safety.

[0086] Specifically, the endovascular medical auxiliary device in the endovascular medical equipment has a gas supply component 110 that can provide independent and precise gas supply to the first split capsule 104 and the second split capsule 108. The control component 112 controls these two gas sources through a first valve group and a second valve group respectively, ensuring that the expansion and contraction of each split capsule can be independently and precisely adjusted. The design of the guide rod 100 enhances the adaptability and smoothness of the device in complex anatomical structures, while the flexible connecting tube 116 further improves the flexibility of the entire device and the stability of fluid transmission.

[0087] According to the second aspect of the present invention, the endocavitary medical device, due to its independent and precise gas control capability, allows doctors to accurately control the expansion and contraction of each segmented capsule, thereby achieving precise positioning and support of the target area. This greatly improves the precision of the surgery and reduces surgical risks. The flexible connecting tube 116 and guide rod 100 design in the device enable it to adapt more flexibly to complex anatomical structures during insertion or movement, reducing the risk of tissue damage. Simultaneously, independent valve group control ensures that even if a segmented capsule malfunctions, it will not affect the operation of the entire device, thus improving surgical safety. The integrated design of the endocavitary medical device simplifies the operation process and reduces surgical difficulty. Doctors can more easily monitor and control the status of each segmented capsule, thereby improving surgical efficiency. Due to its excellent flexibility and precision, the device is applicable to various types of endocavitary surgeries and treatments, such as vascular interventional surgery and cavity dilation surgery. This broadens the application range of the device, allowing more patients to benefit from this advanced medical equipment.
