[0002] Capsule endoscope is a kind of medical equipment for digestive tract examination, it enters body by swallowing capsule-shaped endoscope of patient, utilizes built-in image sensor to capture the image inside digestive tract, and transmits image to external device by radio frequency transceiver controller.

[0003] Although capsule endoscope technology provides a non-invasive method for digestive tract examination, but there are some limitations in prior art. First, traditional capsule endoscope lacks suspension function, which limits its moving ability in digestive tract and detailed examination of specific area. Secondly, due to lack of effective control means, the position and posture of capsule endoscope in body are difficult to accurately adjust, resulting in large difference between near view and far view, which affects image quality. In addition, although magnetic control technology provides a certain degree of suspension ability, its effect is limited, and the examination efficiency is not high. These problems together lead to the limitation of existing capsule endoscope technology in practical application, especially in the case of needing accurate and comprehensive examination of digestive tract. SUMMARY

[0005] To achieve the above-mentioned purpose, the utility model provides a kind of pneumatic suspension capsule endoscope, comprising:

[0006] Shell, provided with camera, battery and circuit board, the shell is filled with gas medium;

[0007] Elastic membrane device, set in the shell, the inside of the elastic membrane device communicates with the shell, when the gas medium enters the elastic membrane device, the elastic membrane device expands, so that the shell obtains lift, realizes suspension.

[0008] In some embodiments, the elastic membrane device is provided with temperature control device, and the temperature control device is used to adjust the temperature of the gas medium to control the lift of the shell.

[0010] Elastic membrane cavity, set in the shell;

[0011] A gas baffle is disposed between the elastic membrane cavity and the housing, and the gas baffle has a gas channel that connects the elastic membrane cavity and the housing.

[0012] In some embodiments, the gas medium includes compressed gas;

[0013] The gas channel is equipped with a heat-fusion structure. The heat-fusion structure blocks the gas channel at a set temperature. When the temperature control device heats the gas to a temperature exceeding the set temperature, the heat-fusion structure melts, the gas channel becomes unobstructed, and the compressed gas automatically enters the elastic membrane cavity, causing the elastic membrane device to expand. The shell then gains lift and achieves levitation.

[0014] In some embodiments, the temperature control device includes a heating electrode disposed on the gas partition.

[0015] In some embodiments, the gaseous medium includes helium.

[0016] In some embodiments, the housing is divided into a separate device cavity and a gas cavity. The device cavity contains the camera, the battery, and the circuit board, and the gas cavity is filled with the gas medium.

[0017] In some embodiments, the elastic membrane device includes an elastic membrane cavity that covers the outer periphery of the housing, and the surface of the elastic membrane cavity is curved.

The shell is equipped with a camera, a battery and a circuit board, and is filled with a gas medium. The elastic membrane device is located in the shell, and the interior of the elastic membrane device is in communication with the shell. When the gas medium enters the elastic membrane device, the elastic membrane device expands, so that the shell obtains lift and achieves suspension.

[0023] In traditional capsule endoscopy technology, the movement of the capsule in the digestive tract is limited due to the lack of effective suspension and positioning mechanisms, which makes it difficult to conduct detailed examination of specific areas and affects the image quality and efficiency of the examination. Especially when precise observation of specific parts of the digestive tract is required, the limitations of traditional technology are more apparent. In addition, due to the inability to effectively control the posture of the capsule, the difference between close-up and long-range images is large, further affecting the accuracy of the examination results.

[0024] To solve these technical problems, the pneumatic suspension capsule endoscope provided by the present application introduces an elastic membrane device and gas medium, which realizes accurate control of the position and posture of the capsule. The shell is filled with gas medium, and when these gases enter the elastic membrane device connected to the shell, the elastic membrane device will expand, providing lift for the shell, allowing the capsule to float in the digestive tract. This pneumatic suspension mechanism allows the capsule to move freely in the digestive tract without the position and posture limitations common in traditional technology.

[0025] Through this design, the capsule endoscope can move more flexibly in the digestive tract, reach the specific area that needs to be examined, and adjust the posture to obtain clearer images. This not only improves the flexibility of the examination, but also improves the accuracy of the examination, as doctors can more accurately control the position of the capsule to obtain higher quality images. In addition, this pneumatic suspension mechanism can also reduce image blurring caused by improper movement of the capsule, further improving the reliability of the examination.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the utility model will be apparently and completely described in combination with the drawings in the embodiments of the utility model. Apparently, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor fall within the protection scope of the utility model.

[0034] In order to make the person skilled in the art better understand the utility model scheme, the utility model will be further described in detail in combination with the drawings and specific embodiments.

[0035] Please refer to Figure 1 , Figure 1 The schematic diagram of the pneumatic suspension capsule endoscope is provided for the embodiment of the utility model.

[0036] In the first specific embodiment, the pneumatic suspension capsule endoscope provided by the utility model mainly comprises a shell 1 and an elastic film device 6. The shell 1 is provided with a camera 2, a battery 3 and a circuit board 4, and the shell 1 is filled with a gaseous medium 5. The elastic film device 6 is arranged in the shell 1, and the inside of the elastic film device 6 is communicated with the shell 1. When the gaseous medium 5 enters the elastic film device 6, the elastic film device 6 expands, so that the shell 1 obtains the lifting force and realizes the suspension.

[0037] The combination of the elastic film device 6 and the shell 1 is mainly based on the expansion characteristics of the gaseous medium 5 and the buoyancy principle. The following is the detailed working principle.

[0038] In the initial state, the shell 1 is filled with gas medium 5, and the elastic membrane device 6 is in an unexpanded state. In the operation step, the gas medium 5 flows from the shell 1 into the elastic membrane device 6, causing the elastic membrane device 6 to expand. In the suspension process, as the elastic membrane device 6 expands, its volume increases, thereby increasing the overall volume of the entire assembly. According to the principle of buoyancy, the buoyant force is proportional to the volume of the displaced fluid. Therefore, when the elastic membrane device 6 expands, the volume of air displaced by the assembly increases, and if this volume increase causes the average density of the assembly to be less than the density of the surrounding air, the assembly will experience an upward buoyant force. In the suspended state, when the elastic membrane device 6 expands to a certain volume such that the average density of the assembly is less than the density of the surrounding air, the buoyant force experienced by the assembly is greater than its own gravity, thereby achieving suspension.

[0039] It should be noted that the specific form of the gas medium 5 is not limited in this embodiment, and the gas medium 5 should be selected as a gas with a density less than air, including but not limited to various types of heated gas, helium, hydrogen, etc.

[0040] In traditional capsule endoscopy technology, the movement of the capsule in the digestive tract is limited due to the lack of effective suspension and positioning mechanisms, which makes detailed examination of specific areas difficult and affects the quality of the images and the efficiency of the examination. In particular, when precise observation of specific parts of the digestive tract is required, the limitations of traditional technology are more apparent. In addition, due to the inability to effectively control the posture of the capsule, the difference between close-up and long-range images is large, further affecting the accuracy of the examination results.

[0041] To address these technical problems, the pneumatic suspension capsule endoscope provided by the present utility model realizes precise control of the position and posture of the capsule through the innovative design of the elastic membrane device 6 and the gas medium 5. The shell 1 is filled with gas medium 5, and when these gases enter the elastic membrane device 6 that is in communication with the shell 1, the elastic membrane device 6 will expand, thereby providing lift for the shell 1, allowing the capsule to float in the digestive tract. This pneumatic suspension mechanism allows the capsule to move freely in the digestive tract without the positional and postural limitations common in traditional technology.

[0042] Through this design, the capsule endoscope can move more flexibly in the digestive tract, reaching the specific areas that need to be examined, and can adjust the posture to obtain clearer images. This not only improves the flexibility of the examination, but also improves the accuracy of the examination, as the doctor can more precisely control the position of the capsule, thereby obtaining higher quality images. In addition, this pneumatic suspension mechanism can also reduce image blurring caused by improper movement of the capsule, further improving the reliability of the examination.

[0043] In combination with the above structure and process, it can be seen that the pneumatic suspension capsule endoscope has at least the following beneficial effects: the pneumatic suspension capsule endoscope effectively overcomes the defect that the traditional capsule endoscope cannot accurately control the position and attitude, and improves the flexibility and accuracy of the digestive tract examination.

[0044] In some embodiments, the elastic membrane device 6 is provided with a temperature control device 7 for adjusting the temperature of the gas medium 5 to control the lifting force of the shell 1.

[0045] In this embodiment, the elastic membrane device 6 is equipped with a temperature control device 7, which is designed to more finely control the lifting force of the shell 1. The function of the temperature control device 7 is to adjust the temperature of the gas medium 5, and through the adjustment of the temperature, the density of the gas medium 5 can be affected, and then the buoyancy of the shell 1 is affected.

[0046] The temperature change of the gas medium 5 will affect its density according to the ideal gas law. When the gas medium 5 is heated, its volume expands and its density decreases; on the contrary, when the gas medium 5 is cooled, its volume shrinks and its density increases. By heating or cooling the gas medium 5 through the temperature control device 7, the density of the gas inside the elastic membrane device 6 can be accurately controlled, thereby controlling the lifting force of the shell 1.

[0047] When the lifting force of the shell 1 needs to be increased, the temperature control device 7 will heat the gas medium 5, causing the gas to expand and the density to decrease, thereby increasing the buoyancy; when the lifting force needs to be reduced or the shell 1 needs to be lowered, the temperature control device 7 can reduce the heating or cooling of the gas medium 5, causing the gas to shrink and the density to increase, thereby reducing the buoyancy. This temperature control provides an effective means to adjust the suspension state of the shell 1, enabling it to be stably suspended in the air or accurately moved in the digestive tract for effective examination.

[0048] In some embodiments, the elastic membrane device 6 comprises:

[0049] The elastic membrane cavity 8 is provided in the shell 1.

[0050] The gas partition plate 9 is provided between the elastic membrane cavity 8 and the shell 1, and the gas partition plate 9 is provided with a gas passage 10 for communication between the elastic membrane cavity 8 and the shell 1.

[0051] In this embodiment, the elastic membrane device 6 is composed of the elastic membrane cavity 8 and the gas partition plate 9, and these two components together realize the control and distribution of the gas medium 5 in the shell 1. The function of the elastic membrane cavity 8 is to contain and expand the gas medium 5, thereby realizing the suspension of the shell 1.

[0052] The gas partition 9 is located between the elastic membrane cavity 8 and the shell 1, and its function is to separate the elastic membrane cavity 8 from the shell 1, while allowing the two to communicate through the gas channel 10. The gas channel 10 is a specially designed structure on the gas partition 9, allowing the gas medium 5 to flow from the shell 1 to the elastic membrane cavity 8, achieving the expansion of the elastic membrane cavity 8.

[0053] This design allows the elastic membrane cavity 8 to expand when the gas medium 5 flows in, while the gas partition 9 ensures that the flow of the gas medium 5 is controlled, preventing the gas medium 5 from diffusing in disorder. The design of the gas channel 10 allows precise control of the speed and amount of gas medium 5 flowing into the elastic membrane cavity 8, which is crucial for adjusting the lift of the shell 1 and the suspension state.

[0054] In some cases, by adjusting the opening and closing of the gas channel 10 or its flow area, the amount of gas in the elastic membrane cavity 8 can be finely adjusted, thereby controlling the expansion of the elastic membrane cavity 8 and the lift of the shell 1. The design of this structure improves the maneuverability and stability of the suspension capsule endoscope, enabling it to effectively perform examination and treatment in the digestive tract.

[0055] In some embodiments, the gas medium 5 includes compressed gas;

[0056] The gas channel 10 is provided with a hot melt structure 11, which blocks the gas channel 10 at a set temperature. When the temperature control device 7 is heated to exceed the set temperature, the hot melt structure 11 melts, the gas channel 10 is unblocked, and the compressed gas automatically enters the elastic membrane cavity 8, causing the elastic membrane device 6 to expand, the shell 1 to obtain lift, and the suspension to be achieved.

[0057] In this embodiment, the gas medium 5 refers to compressed gas, which is stored in the shell 1 in the initial state. The gas channel 10 is a channel connecting the shell 1 and the elastic membrane cavity 8, and is provided with a hot melt structure 11, which is a special structure that can change its physical state under certain temperature conditions.

[0058] The hot melt structure 11 remains solid when not heated or heated below its melting point, thereby blocking the gas channel 10 and preventing the gas medium 5 from flowing from the shell 1 into the elastic membrane cavity 8. When the temperature control device 7 heats the gas partition 9 to a temperature exceeding the set melting point of the hot melt structure 11, the hot melt structure 11 changes from solid to liquid, causing the gas channel 10 to be unblocked.

[0059] Once the gas channel 10 is unblocked, the compressed gas will automatically flow into the elastic membrane cavity 8. With the inflow of compressed gas, the elastic membrane cavity 8 begins to expand, which causes the shell 1 to obtain upward lift. When the lift is large enough to overcome the gravity of the shell 1, the shell 1 achieves suspension.

[0060] This design allows precise control of the timing of the melting of the hot melt structure 11 by the temperature control device 7, thereby controlling the timing of the inflow of compressed gas into the elastic membrane cavity 8, and further controlling the expansion of the elastic membrane device 6 and the suspension state of the housing 1. Such a mechanism provides an effective method to control the suspension and movement of the capsule endoscope, enabling precise examination within the digestive tract.

[0061] In some embodiments, the temperature control device 7 includes a heating electrode, which is disposed on the gas partition 9.

[0062] In this embodiment, the temperature control device 7 includes a heating electrode, which is directly disposed on the gas partition 9. The role of the heating electrode is to provide heat to heat the gas partition 9 and its hot melt structure 11 and gas medium 5 when needed.

[0063] By integrating the heating electrode on the gas partition 9, the temperature of the hot melt structure 11 in the gas channel 10 can be effectively controlled. When the heating electrode is activated, it generates heat that raises the temperature of the gas partition 9, which is then transmitted to the hot melt structure 11. This temperature rise causes the hot melt structure 11 to change from a solid state to a liquid state, especially when the temperature exceeds the set melting point of the hot melt structure 11.

[0064] Once the hot melt structure 11 melts, it will no longer block the gas channel 10, allowing the compressed gas medium 5 to flow into the elastic membrane cavity 8. This design allows precise control of the timing of the inflow of the gas medium 5 into the elastic membrane cavity 8 by the temperature control device 7, thereby controlling the expansion of the elastic membrane device 6 and the suspension state of the housing 1.

[0065] This integrated heating electrode design improves the response speed and control accuracy of the system, as it allows rapid and direct heating of the key component affecting gas flow - the hot melt structure 11. Such a design enables the aerodynamic suspension capsule endoscope to be more flexible and accurate in controlling its suspension and movement within the digestive tract, thereby improving the efficiency and effectiveness of the examination.

[0066] In some embodiments, the gas medium 5 includes helium.

[0067] In this embodiment, the gas medium 5 uses helium, which is a lightweight and chemically stable inert gas.

[0068] Using helium as the suspension medium for the endoscope can significantly reduce the overall density of the housing 1, as the density of helium is much lower than that of air. This low-density characteristic makes it easier for the housing 1 to obtain sufficient buoyancy when the elastic membrane device 6 expands, thereby achieving suspension. In addition, the safety of helium is also an important consideration, as it is not flammable or combustible, which reduces the potential risks when using an aerodynamic suspension capsule endoscope in medical examinations.

[0069] Helium has good thermal conductivity, which means that when the temperature control device 7 heats the gas barrier 9, helium can quickly respond to temperature changes and expand or contract in time to provide the required lift for the shell 1. At the same time, the biocompatibility of helium ensures that even in the extreme case of gas leakage, it will not cause harm to the human body.

[0070] In addition, the gas medium 5 can also be air, preferably compressed air.

[0071] Please refer to Figure 2 and Figure 3 , wherein, Figure 2 is a schematic diagram of a pneumatic suspension capsule endoscope provided by another embodiment of the present utility model, Figure 3 is an effect diagram of a pneumatic suspension capsule endoscope provided by another embodiment of the present utility model.

[0072] As Figure 2 shown, it is the state before the elastic membrane device 6 expands, and as Figure 3 shown, it is the state after the elastic membrane device 6 expands.

[0073] In some embodiments, the shell 1 is divided into an independent device cavity 12 and a gas cavity 13. The device cavity 12 is provided with a camera 2, a battery 3 and a circuit board 4, and the gas cavity 13 is filled with a gas medium 5.

[0074] In this embodiment, the shell 1 is designed as two independent cavities, namely the device cavity 12 and the gas cavity 13. This cavity design allows more rational space utilization and higher efficient function isolation. The device cavity 12 is a space for accommodating key components, including the camera 2, the battery 3 and the circuit board 4. These components are the core part of the endoscope, responsible for capturing images, providing energy and controlling the operation of the endoscope. Placing these sensitive components in the device cavity 12 can protect them from the pressure changes of the gas medium 5 in the gas cavity 13, while also facilitating maintenance and replacement.

[0075] The gas cavity 13 is a cavity specially designed to accommodate the gas medium 5. This cavity is responsible for storing the gas medium 5 that provides the suspension function, such as helium mentioned earlier, or compressed air, etc. The design of the gas cavity 13 allows the gas medium 5 to expand or contract during the operation of the endoscope, thereby adjusting the buoyancy and position of the endoscope. By controlling the inflow and outflow of the gas medium 5, precise control of the suspension state of the endoscope can be achieved, allowing it to stably suspend or move as needed in the digestive tract.

[0076] This compartmentalized design also helps to optimize the weight distribution and balance of the endoscope. The components in the device cavity 12 are generally heavier, while the gas medium 5 in the gas cavity 13 is lighter. With proper layout, it can be ensured that the endoscope remains stable when suspended, avoiding rolling or tilting due to uneven weight distribution, thereby improving the accuracy and comfort of the examination. Overall, this design improves the operational efficiency and safety of the aerodynamic suspension capsule endoscope, making it more suitable for medical examination and treatment.

[0077] In some embodiments, the elastic membrane device 6 includes an elastic membrane cavity 8, which is wrapped around the outer periphery of the shell 1, and the surface of the elastic membrane cavity 8 is curved.

[0078] In this embodiment, this design allows the elastic membrane cavity 8 to deform more uniformly and smoothly when the gas medium 5 flows in, i.e., to expand, thereby increasing the overall volume of the shell 1.

[0079] The effect of the gas medium 5 on the suspension of the endoscope mainly lies in its driving effect on the expansion of the elastic membrane cavity 8. When the gas medium 5 is introduced into the elastic membrane cavity 8, due to the expansibility of the gas, the elastic membrane cavity 8 will expand outward, forming a larger curved surface. This expansion directly increases the volume of the shell 1 that displaces the surrounding medium, such as the liquid or gas in the digestive tract. According to Archimedes' principle, the buoyancy experienced by an object in a fluid is equal to the weight of the fluid it displaces. Therefore, as the elastic membrane cavity 8 expands, the volume of gas or liquid displaced by the shell 1 increases, and the corresponding buoyancy also increases.

[0080] When the buoyancy is greater than the weight of the shell 1, the shell 1 will begin to rise, achieving suspension. This suspension mechanism allows the endoscope to move freely in the digestive tract, without being limited by the downward force of gravity as with traditional endoscopes. By precisely controlling the amount of gas medium 5 flowing in, the degree of expansion of the elastic membrane cavity 8 can be adjusted, thereby finely controlling the suspension state and position of the shell 1.

[0081] In some embodiments, the first end of the shell 1 is provided with a camera 2, and the second end of the shell 1 is provided with a gas cavity 13.

[0082] At the first end of the shell 1, the edge of the elastic membrane cavity 8 surrounds the camera 2, and at the second end of the shell 1, the edge of the elastic membrane cavity 8 surrounds the gas cavity 13.

[0083] In this embodiment, the design of the shell 1 has clear functional zones, with the first end equipped with a camera 2 for capturing images in the body, and the second end provided with a gas cavity 13 for storing the gas medium 5. This layout allows the camera 2 to focus on image acquisition, while the gas cavity 13 can independently manage the gas medium 5 to achieve the suspension function of the endoscope.

[0084] The elastic membrane cavity 8 also has specific structural features. Its edge surrounds the camera 2 at the first end of the shell 1, providing additional protection and support for the camera. This surrounding design helps to secure the camera 2, reducing vibration and friction during movement in the body, ensuring image stability and clarity. At the second end of the shell 1, the edge of the elastic membrane cavity 8 surrounds the gas cavity 13, which has a gas port that can be filled with gas medium before use, and the elastic membrane cavity 8 does not interfere with the inflation operation of the gas port.

[0085] In some embodiments, the temperature control device 7 is signal connected with the circuit board 4.

[0086] The circuit board 4 is provided with a radio transceiver control circuit, which is used to receive instructions through radio waves to control the temperature control device 7 to adjust the temperature of the gas medium 5, thereby controlling the lift of the shell 1.

[0087] In this embodiment, a signal connection is established between the temperature control device 7 and the circuit board 4, which allows the temperature control device 7 to receive control signals from the circuit board 4. The circuit board 4 is integrated with a radio transceiver control circuit, which is designed to receive external instructions through radio waves.

[0088] When the external control device sends instructions to the endoscope through radio waves, the radio transceiver control circuit can capture these instructions and convert them into corresponding control signals. These signals are then used to adjust the temperature control device 7, thereby adjusting the temperature of the gas medium 5. By precisely controlling the temperature of the gas medium 5, its density can be affected, as the density of the gas changes with temperature.

[0089] The adjustment of the temperature causes the volume and density of the gas medium 5 to change, which directly affects the degree of expansion of the gas in the elastic membrane cavity 8, thereby affecting the lift of the shell 1. When the gas medium 5 is heated, its volume expands, causing the elastic membrane cavity 8 to expand and increase the lift of the shell 1; conversely, if the gas medium 5 is cooled, its volume shrinks, causing the elastic membrane cavity 8 to shrink and reduce the lift of the shell 1.

[0090] This design allows the levitation state of the endoscope to be remotely controlled, improving the flexibility and accuracy of the operation. The doctor or operator can adjust the position and levitation state of the endoscope in real time according to the needs of the examination to obtain the best examination angle and effect. This wireless control mechanism provides a high-efficiency and rapid-response control method for the aerodynamic levitation capsule endoscope, making it more effective and safe in medical examination and treatment.

[0091] In some cases, the hot melt structure 11 uses low-melting-point paraffin, the gas medium 5 uses compressed air, and the elastic membrane device 6 uses a balloon.

[0092] In one specific embodiment, the use of the aerodynamic suspension capsule endoscope is described as follows.

[0093] When the patient is ready for the gastrointestinal examination, the aerodynamic suspension capsule endoscope is first swallowed. The shell 1 of the endoscope contains a device cavity 12 and a gas cavity 13, where the device cavity 12 is built-in with a camera 2, a battery 3 and a circuit board 4, and the gas cavity 13 is filled with a gas medium 5, such as compressed air or helium. The elastic membrane device 6 includes an elastic membrane cavity 8, which is wrapped around the outer circumference of the shell 1 and forms a curved surface on the surface.

[0094] When the examination begins, the doctor sends a radio command through the external control device, which is received by the circuit board 4 through the radio transceiver control circuit. The circuit board 4 then controls the temperature control device 7 through the signal connection, which can be a heating electrode integrated on the gas partition 9. The temperature control device 7 is activated and heats the gas partition 9, causing the hot melt structure 11, such as low-melting-point paraffin, to reach the melting point and melt.

[0095] After the hot melt structure 11 melts, the originally blocked gas passage 10 is unblocked, and the compressed gas medium 5 automatically flows from the gas cavity 13 into the elastic membrane cavity 8. With the inflow of the gas medium 5, the elastic membrane cavity 8 expands, causing the overall volume of the shell 1 to increase, thereby displacing more air or liquid, which increases the buoyancy of the shell 1 according to Archimedes' principle. When the buoyancy exceeds the weight of the shell 1, the shell 1 begins to rise, achieving suspension in the digestive tract.

[0096] By finely adjusting the heating level of the temperature control device 7, the doctor can control the expansion of the elastic membrane cavity 8, and thus accurately control the lifting force of the shell 1. This temperature control mechanism allows the doctor to adjust the suspension height and stability of the endoscope according to the needs of the examination. For example, if the endoscope needs to be closer to a certain area of the digestive tract, the heating can be reduced, causing the gas medium 5 to slightly contract, thereby reducing the buoyancy of the shell 1 and causing it to descend. Conversely, if the endoscope needs to be maintained at the current position or raised, the heating can be increased, causing the gas medium 5 to further expand and increase the buoyancy.

[0097] In the suspended state, the endoscope can be more flexible to move to the specific area that needs to be examined and adjust the posture to obtain a clear image. The doctor can adjust the position and suspension state of the endoscope in real time to obtain the best examination angle and effect. This aerodynamic suspension mechanism reduces the image blur caused by improper movement of the capsule, improving the reliability and accuracy of the examination.

[0098] Throughout the process, the aerodynamic suspension capsule endoscope effectively overcomes the defect of traditional capsule endoscopes that cannot accurately control the position and posture, significantly improving the flexibility and accuracy of the gastrointestinal examination.

[0099] It should be noted that the many components mentioned in the utility model are general standard components or components known to those skilled in the art, the structure and principle of which can be known by the technical personnel through a technical manual or through a conventional experimental method.

[0100] It should be noted that in the present specification, relational terms such as first and second are used merely to distinguish one entity from another, and do not necessarily require or imply that any such actual relationship or order exists between or among the entities.

[0101] The above has carried out the detailed introduction to the pneumatic suspension capsule endoscope provided by the utility model. The principle and implementation mode of the utility model are described in this paper by applying specific examples, and the above embodiment description is only used to help understand the method and core idea of the utility model. It should be pointed out that for ordinary skilled personnel in the technical field, some improvements and modifications can be made to the utility model without departing from the principle of the utility model, and these improvements and modifications also fall within the protection scope of the utility model claims.
