Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an ultrasonic probe with a panoramic detection effect. Background Art

[0002] An ultrasonic probe with a panoramic detection effect is an ultrasonic imaging device that can provide a wide viewing angle and is usually used in fields such as medical diagnosis and industrial inspection. Its main feature is the ability to image within a relatively large viewing angle range, thereby providing more comprehensive detection information. Wide viewing angle: The panoramic ultrasonic probe realizes the transmission and reception of ultrasonic beams in multiple directions through multi-array or specific structural design, covering a larger area and generating a panoramic image. Multi-dimensional imaging: This probe can perform two-dimensional or even three-dimensional imaging, generating more detailed images than traditional probes. This is particularly useful for the diagnosis of complex tissue structures or the inspection of complex equipment. High resolution: Probes with a panoramic detection effect are usually equipped with high-frequency ultrasonic emission devices, which can capture more subtle structural changes and achieve high-resolution imaging. Fast scanning: Due to the large viewing angle range, the panoramic probe can complete large-area scanning in a relatively short time, reducing the detection time. Wide application: In the medical field, panoramic ultrasonic probes can be used for comprehensive examinations of parts such as the abdomen, heart, and musculoskeletal system; in the industrial field, they are suitable for scenarios such as material detection and structural integrity assessment.

[0003] Currently, instruments for detecting the morphology inside a lumen using a mechanically rotating single working unit (such as IVUS, OCT) or an array phased array (such as ICE) can only obtain lateral information of the catheter, and due to their structural characteristics, there will be a large blind area at the central position of the imaging area, resulting in the inability of the corresponding image information results to directly guide the use of treatment instruments that require a forward viewing field.

[0004] In view of the above situation, in order to overcome the above technical problems, the present invention designs an ultrasonic probe with a panoramic detection effect, which solves the above technical problems. Summary of the Invention

[0005] The technical objective to be achieved by the present invention is to work in a manner of a single detector spiraling forward, while acquiring data information in front of and on the side of the target lumen.

[0006] In order to achieve the above technical objective, the present invention provides the following technical solutions:

[0007] An ultrasonic probe with panoramic detection effect, the probe head includes six main components: a protective component, a telescopic rod, a fixed block, a rotating component, a detection mechanism and a detector. The mutual cooperation of these components enables the probe head to perform all-round ultrasonic detection in a complex environment. The protective component is located at the outermost layer of the probe head and plays a protective role. This component can not only effectively protect the internal precision structure from damage by the external environment, but also ensure the stability and durability of the probe head when working. The material of the protective component is usually corrosion-resistant and impact-resistant to ensure that it can still work normally under various harsh conditions. The telescopic rod is installed on the surface of the protective component, and its main function is to provide an adjustable length so that the probe head can adapt to the detection needs of different depths and distances. By adjusting the length of the telescopic rod, the probe head can be flexibly used in different application scenarios to ensure the accuracy and reliability of the detection. The design of the telescopic rod usually takes into account mechanical stability, and can withstand a certain load during use to prevent the probe head from displacement or vibration during operation. The fixed block is located at the outer end of the telescopic rod and plays a role in stabilizing the position of the probe head. Through the adjustment of the telescopic rod, the fixed block can be fixed in a suitable position, thereby providing a stable base point for subsequent detection operations. The design of the fixed block often takes into account the compatibility with various installation environments. Whether it is a flat surface, a curved surface or other complex surfaces, the fixed block can be firmly attached to avoid displacement and jitter during the detection process. Inside the detection head, the rotating component is installed in the protection component. The function of this component is to drive the detection mechanism through rotational motion. This rotational motion can make the detection mechanism move in a spiral forward manner, expanding the detection range of the detector. The design of spiral motion enables the detection head to achieve a more comprehensive coverage without moving the entire device, which is particularly important for occasions requiring high-precision detection. The detection mechanism is also installed inside the protection component, and it works closely with the rotating component. The detection mechanism receives power from the rotating component, allowing the detector installed on it to perform complex movements, thereby covering a larger detection range. The detection mechanism is usually designed as a device with high-precision movement capabilities to ensure that the detector can move smoothly and accurately during the scanning process. The detector is installed on the end face of the detection mechanism, and its position is designed on the top bevel of the detection head. This design helps the detector achieve a wide range of detection angles and maximizes the detection range. The detector is responsible for transmitting and receiving ultrasonic signals, combined with the movement of the detection mechanism to achieve a full range of scanning of the target area. Through the combination of spiral motion and inclined design, the detector can cover the detection area more comprehensively and provide high-precision panoramic imaging effects.

[0008] The design of the protection component is precise, including parts such as a housing, a limiting chute, a horizontal limiting groove, a clamping groove, and a rolling groove. The housing, as the main body of the protection component, adopts a sleeve-like structure, which can provide comprehensive protection for internal components. The inner surface of the housing is provided with a limiting chute. This design allows internal components to move along a specific trajectory, ensuring their stability during operation. The side of the limiting chute is provided with a horizontal limiting groove, which further restricts the horizontal movement range of the components and prevents them from shifting. To enhance the connection stability, a clamping groove is provided above the horizontal limiting groove for fixing connection components. A rolling groove is also provided on the outer side of the clamping groove, providing additional support and flexibility to ensure the smooth operation of the detection head during operation.

[0009] The cross-sectional shape of the horizontal limiting groove is set to be semi-circular, and the width value of the clamping groove is set to be half of the width value of the rolling groove. Designing the cross-sectional shape of the horizontal limiting groove as semi-circular and setting the width value of the clamping groove to be half of the width value of the rolling groove has significant advantages in terms of structural stability and operational flexibility. The semi-circular cross-sectional horizontal limiting groove can effectively enhance the limiting function. Since the semi-circular shape can better match the circular or arc-shaped components it contacts, it can provide more stable support and more precise limiting, preventing unexpected horizontal offsets of the components during sliding. At the same time, the semi-circular design can also reduce the friction between the contact surfaces, making the relevant components move more smoothly. The width of the clamping groove is set to be half of the width of the rolling groove, which helps to optimize the compactness and coordination of the overall structure. The narrower clamping groove can firmly lock the connection components, preventing them from falling off or loosening, while the wider rolling groove provides more movement space, allowing internal components to make appropriate adjustments and roll. This design of the width ratio ensures both the stability of the structure and the flexibility and freedom of the components during operation, enabling the entire device to still operate efficiently under complex working conditions.

[0010] The design of the rotating component includes a rotating sleeve, a limiting ring, a spiral groove, an inner ring gear, and a driving gear, aiming to achieve precise and stable rotational motion. First, the rotating sleeve is installed inside the protection component. As the core structure of the rotating component, its stability directly affects the operation effect of the entire device. The surface of the sleeve is designed with a spiral groove. This spiral-shaped groove can guide internal components to rotate or move along a specific trajectory, thus achieving complex motion patterns.

[0011] To ensure the positioning and stability of the sleeve during rotation, limit rings are installed on both sides of the sleeve. These limit rings can effectively restrict the lateral movement of the rotating sleeve, avoiding the influence on the rotation accuracy caused by unnecessary displacement. On the inner side of one end of the rotating sleeve, inner ring teeth are also designed. These gears mesh with other gears inside the device to form a precise gear transmission system. Matched with the inner ring teeth is the drive gear installed on its inner side. The function of the drive gear is to transmit power to the rotating sleeve and drive it to rotate along the set trajectory. The design of the entire rotating assembly ensures that a smooth and precise rotational motion can be provided during operation, improving the overall performance and reliability of the device.

[0012] The detection mechanism consists of a detection sleeve, a top inclined surface, a matching component, and a rolling bearing, aiming to achieve an efficient detection function. The detection sleeve is installed inside the rotating assembly. As the core component of the detection mechanism, its stability and precision directly affect the detection effect. The end face of the detection sleeve is designed with a top inclined surface. This inclined surface design enables the detector to scan the target area at a specific angle, thereby expanding the detection range and improving the comprehensiveness and accuracy of imaging.

[0013] To ensure the precise positioning of the detection sleeve during rotation and movement, the matching component is installed on the surface of the detection sleeve. This component closely cooperates with other components to ensure the smoothness of the detection mechanism during operation. The rolling bearing is installed in the middle of the matching component. As a key supporting component of the detection mechanism, the rolling bearing can significantly reduce the friction during rotation, ensuring that the detection sleeve moves more smoothly and stably. This design not only improves the detection efficiency but also extends the service life of the device, ensuring that it still maintains efficient operation during long-term use.

[0014] The top inclined surface is arranged to incline inward. The detector is arranged at the center of the top inclined surface and is perpendicular to the top inclined surface. Arranging the top inclined surface to incline inward and installing the detector at the center of the top inclined surface and perpendicular to the inclined surface has significant advantages in terms of improving the detection range and detection accuracy.

[0015] The design of the top inclined surface inclining inward enables the detector to contact and scan the target area at a wider angle. This inclined angle allows the detector to receive reflected signals from multiple directions, greatly expanding the detection range and helping to obtain more comprehensive detection information. This is particularly important for application scenarios that require full-range scanning of complex structures or irregular surfaces. The detector is arranged perpendicular to the top inclined surface, ensuring that the signal emission and reception directions of the detector are consistent with the inclined surface, thereby optimizing the directivity of the detection signal. Such a design can maximize the utilization rate of ultrasonic or other detection signals, reduce signal loss and interference, and improve the sensitivity and accuracy of detection. The detector can more accurately capture echo signals from different angles, thereby providing a clearer and more detailed imaging effect.

[0016] The detection sleeve includes a sleeve body, a rotating gear ring, a rotating gear, and a micro brushless motor. There are 2 sleeve bodies, which are the front and rear parts of the detection sleeve respectively. The rotating gear ring is arranged on the bottom surface of the sleeve body. The rotating gear is meshed with the rotating gear ring. The micro brushless motor is installed inside the other sleeve body.

[0017] The matching component consists of two connecting blocks and a rotating shaft. This design ensures the stability and flexibility of the detection mechanism. The two connecting blocks are respectively arranged on the upper part of the detection sleeve. The lower connecting block is directly installed on the upper part of the detection sleeve to play a role in fixing and supporting. The rotating shaft is installed between the two connecting blocks. The connecting blocks can rotate smoothly through the rotating shaft, ensuring that the detection mechanism can move smoothly and accurately during operation, improving the working efficiency and reliability of the overall device.

[0018] In addition to the connecting blocks and the rotating shaft, the matching component further includes a rotating shaft and a rolling wheel to improve the flexibility and stability of the system. The rotating shaft is cleverly arranged on the side of the upper connecting block to provide additional support and rotation function. The rolling wheel is installed on the end face of the rotating shaft, making the overall structure move more smoothly during movement. The rolling wheel is designed to closely cooperate with the rotating shaft and can rotate freely in the connecting block, ensuring low friction and high efficiency during the operation of the detection mechanism. This design not only improves the smoothness of the component operation, but also effectively reduces wear, extends the service life of the equipment, and ensures high-precision operation during the detection process.

[0019] The main body of the rolling and rotating bearing is set as a rotating bearing ring. The inner diameter value of the rotating bearing ring is set equal to the outer diameter value of the rotating shaft. The inner diameter value of the rotating bearing ring is exactly equal to the outer diameter value of the rotating shaft, ensuring the precise fit between the rotating bearing and the rotating shaft. This precise fit reduces the clearance, enabling the rotating shaft to rotate smoothly in the rotating bearing, thereby improving the stability and operation accuracy of the overall system. The precise fit reduces unnecessary friction and wear. The reduction of friction not only improves the operating efficiency, but also reduces heat generation and energy consumption of the system, thus enhancing the overall performance and service life of the equipment. The good fit can prevent the relative displacement between the rotating bearing and the rotating shaft, reducing vibration and noise caused by asymmetry or clearance. This stability and reliability are particularly important for application scenarios with high-precision requirements, ensuring the stable operation of the equipment during long-term use. Due to the high fit precision, less wear occurs during the operation of the equipment, thereby reducing the frequency of maintenance and repair. The reduction of maintenance requirements also reduces the long-term use cost.

[0020] The interior of the bearing ring is provided with rolling beads that can move freely, and 60%-70% of the main body of the rolling beads is arranged inside the bearing ring. The rolling beads move freely inside the bearing ring, which can significantly reduce the frictional resistance between the rotating shaft and the bearing ring. Compared with traditional sliding bearings, the design of rolling beads reduces the frictional force on the contact surface, thereby improving the rotation efficiency and the running stability of the equipment. The rolling beads can distribute the force evenly, reduce the direct friction between the contact surfaces, and reduce the wear rate. This design of dispersing the force helps to extend the service life of the rolling bearing and the rotating shaft, and reduces the frequency of maintenance and replacement. The rolling beads effectively disperse the pressure on the bearing ring and improve the load-bearing capacity of the rolling bearing. The design of the rolling beads enables the rolling bearing to withstand a large load and is suitable for high-load or high-speed application scenarios. The movement of the rolling beads inside the bearing ring can provide better stability. Since 60%-70% of the main body of the rolling beads is inside the bearing ring, this part of the design can ensure that the rolling beads remain stable during movement, are not easily detached or unbalanced, thereby enhancing the stability of the entire bearing system. The uniform distribution and free movement of the rolling beads can reduce the noise and vibration caused by uneven friction. This design helps to provide a quieter operating environment and reduce the impact of vibration on the equipment and its surrounding environment. Most of the main body of the rolling beads is arranged inside the bearing ring, which helps to enhance the sealing performance and prevent dust and foreign objects from entering the bearing system. This sealing performance can protect the lubricant inside the bearing and further improve the working efficiency and service life of the bearing.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. In the case of using only one detector, the present invention simultaneously obtains the information of the lumen conditions in front of and on the side of the catheter. This design significantly optimizes the structure of the ultrasonic detection system and brings many remarkable advantages. First, by using a transducer working unit to achieve the detection of the front and side of the lumen, this solution greatly reduces the number of signal channels. In traditional ultrasonic detection systems, multiple detectors and complex signal channels are usually required to achieve comprehensive detection. This not only increases the complexity of the system but also brings higher manufacturing and maintenance costs. However, this solution completes multi-directional detection with a single detector, effectively simplifies the system design, and reduces the complexity and cost of the equipment. Second, reducing the number of signal channels and streamlining the system structure make the overall layout of the ultrasonic detection system more compact. The direct benefit of this compact design is that there is more physical space inside the catheter for carrying other functional devices. For example, in medical applications, these additional spaces can be used to integrate more sensors, control modules, or other auxiliary functions, which will greatly expand the functionality and application scope of the catheter. In the field of industrial inspection, these spaces can also be used to add more detection modules or optimize the existing detector settings, thereby improving the detection ability of the overall system. While improving the detection efficiency, this technical solution also enhances the reliability of the system. The reduction of redundant signal channels and complex wiring reduces the possibility of signal interference, enhances the stability and data accuracy of the system. Due to the reduction of signal channels, the noise and interference sources in the system are also correspondingly reduced, thus improving the clarity and accuracy of detection.

[0023] 2. Compared with the existing medical endo-ultrasonic imaging solutions, the present technical solution has significant advantages in obtaining lumen information. Traditional endo-ultrasonic systems often face the problem of blind spots where imaging cannot be performed in the center of the catheter. These blind spots usually cannot obtain clear images due to the limitations of the detector's position and signal propagation direction, thus affecting the comprehensive understanding of the internal structure of the lumen. However, this technical solution enables the detector to perform effective imaging simultaneously in the front and side of the catheter, avoiding the appearance of these blind spots. The intelligent configuration of the transducer working unit and the efficient signal processing technology ensure that there are no longer blind spots in the imaging of the central area of the catheter, thus achieving complete imaging of the entire lumen. This all-round imaging ability not only improves the continuity and clarity of the images but also enhances the detection and analysis ability of abnormal conditions in the lumen, enabling doctors or engineers to obtain more comprehensive and accurate internal structure information. This complete imaging solution has significant application value in medical diagnosis and industrial inspection and can provide more accurate evaluation and decision-making support.

[0037] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0038] As shown in the figure,

[0039] Such as Figures 1-10As shown, an ultrasonic probe with panoramic detection effect includes six main components: a protective component 1, a telescopic rod 2, a fixed block 3, a rotating component 4, a detection mechanism 5 and a detector 6. The mutual cooperation of these components enables the probe to perform all-round ultrasonic detection in a complex environment. The protective component 1 is located at the outermost layer of the probe and plays a protective role. This component can not only effectively protect the internal precision structure from damage by the external environment, but also ensure the stability and durability of the probe when working. The material of the protective component 1 is usually selected from corrosion-resistant and impact-resistant materials to ensure that it can still work normally under various harsh conditions. The telescopic rod 2 is installed on the surface of the protective component 1, and its main function is to provide an adjustable length so that the probe can adapt to the detection requirements of different depths and distances. By adjusting the length of the telescopic rod 2, the probe can be flexibly used in different application scenarios to ensure the accuracy and reliability of the detection. The design of the telescopic rod 2 usually takes into account mechanical stability, and can withstand a certain load during use to prevent the probe from displacement or vibration during operation. The fixed block 3 is located at the outer end of the telescopic rod 2 and plays a role in stabilizing the position of the probe. By adjusting the telescopic rod 2, the fixed block 3 can be fixed in a suitable position, thereby providing a stable base point for subsequent detection operations. The design of the fixed block 3 often takes into account the compatibility with various installation environments. Whether it is a plane, a curved surface or other complex surfaces, the fixed block 3 can be firmly attached to avoid displacement and shaking during the detection process. Inside the detection head, the rotating component 4 is installed in the protection component 1. The function of this component is to drive the detection mechanism 5 through a rotational motion. This rotational motion can make the detection mechanism 5 move in a spiral forward manner, expanding the detection range of the detector 6. The design of the spiral motion enables the detection head to achieve a more comprehensive coverage without moving the entire device, which is particularly important for occasions requiring high-precision detection. The detection mechanism 5 is also installed inside the protection component 1, and it is closely matched with the rotating component 4. The detection mechanism 5 receives power from the rotating component 4, so that the detector 6 installed thereon can perform complex movements, thereby covering a larger detection range. The detection mechanism 5 is usually designed as a device with high-precision movement capability to ensure that the detector 6 can move smoothly and accurately during the scanning process. The detector 6 is installed on the end face of the detection mechanism 5, and its position is designed on the top inclined surface 52 of the detection head. Such a design helps the detector 6 to achieve a wide range of detection angles and maximize the detection range. The detector 6 is responsible for transmitting and receiving ultrasonic signals, and combined with the movement of the detection mechanism 5, it realizes a full-range scan of the target area. Through the combination of spiral motion and inclined design, the detector 6 can cover the detection area more comprehensively and provide a high-precision panoramic imaging effect.

[0040] like Figures 2-3As shown in the figure, the protection component 1 is precisely designed and includes parts such as a housing 11, a limit chute 12, a horizontal limit groove 13, a clamping groove 14, and a rolling groove 15. The housing 11 serves as the main body of the protection component 1 and adopts a sleeve-like structure, which can provide comprehensive protection for internal components. The inner surface of the housing 11 is provided with a limit chute 12. This design allows internal components to move along a specific trajectory, ensuring their stability during operation. A horizontal limit groove 13 is provided on the side of the limit chute 12 to further limit the horizontal movement range of the component and prevent it from shifting. To enhance the connection stability, a clamping groove 14 is provided above the horizontal limit groove 13 for fixing and connecting components. A rolling groove 15 is also provided outside the clamping groove 14 to provide additional support and flexibility, ensuring the smooth operation of the detection head during operation.

[0041] As Figure 3 shown in the figure, the cross-sectional shape of the horizontal limit groove 13 is set to be semi-circular, and the width value of the clamping groove 14 is set to be half of the width value of the rolling groove 15. Designing the cross-sectional shape of the horizontal limit groove 13 as semi-circular and setting the width value of the clamping groove 14 to be half of the width value of the rolling groove 15 has significant advantages in terms of structural stability and operation flexibility. The semi-circular cross-sectional horizontal limit groove 13 can effectively enhance the limiting function. Since the semi-circular shape can better match the circular or arc-shaped components in contact with it, it can provide more stable support and more precise limiting, preventing unexpected horizontal displacement of the component during sliding. At the same time, the semi-circular design can also reduce the friction between the contact surfaces, making the relevant components move more smoothly. The width of the clamping groove 14 is set to be half of the width of the rolling groove 15, which helps to optimize the compactness and coordination of the overall structure. The relatively narrow clamping groove 14 can firmly lock the connecting component to prevent it from falling off or loosening, while the relatively wide rolling groove 15 provides more movement space, allowing the internal component to make appropriate adjustments and roll. This design of the width ratio not only ensures the structural stability but also ensures the flexibility and freedom of the component during operation, so that the entire device can still operate efficiently under complex working conditions.

[0042] As Figure 4 shown in the figure, the rotation component 4 is designed to include a rotating sleeve 41, a limit ring 42, a spiral groove 43, an inner ring gear 44, and a driving gear 45, aiming to achieve precise and stable rotational motion. First of all, the rotating sleeve 41 is installed inside the protection component 1. As the core structure of the rotation component 4, its stability directly affects the operation effect of the entire device. The surface of the sleeve is designed with a spiral groove 43. This spiral groove can guide internal components to rotate or move along a specific trajectory, thus realizing complex motion modes.

[0043] To ensure the positioning and stability of the sleeve during rotation, limit rings 42 are installed on both sides of the sleeve. These limit rings 42 can effectively restrict the lateral movement of the rotating sleeve 41, avoiding the influence on the rotation accuracy due to unnecessary displacement. On the inner side of one end of the rotating sleeve 41, inner ring teeth 44 are also designed. These gears mesh with other gears inside the device to form a precise gear transmission system. Matched with the inner ring teeth 44 is the drive gear 45 installed on its inner side. The function of the drive gear 45 is to transmit power to the rotating sleeve 41 and drive it to rotate along the set trajectory. The design of the entire rotating assembly 4 ensures that a smooth and precise rotational motion can be provided during operation, improving the overall performance and reliability of the device.

[0044] As Figure 5 shown, the detection mechanism 5 is composed of a detection sleeve 51, a top inclined surface 52, a matching component 53, and a rolling bearing 54, aiming to achieve an efficient detection function. The detection sleeve 51 is installed inside the rotating assembly 4. As the core component of the detection mechanism 5, the detection sleeve 51 is set in two parts. The latter part serves as the power part, while the former part serves as the rotating part. A miniature power source (motor) is arranged inside the detection sleeve 51 to drive the former part to rotate. And the rotation action control of the detection sleeve 51 is consistent with that of the drive gear 45, so as to realize the simultaneous advancement and rotation of the detection sleeve 51 and achieve a spiral advancement route. Its stability and precision directly affect the detection effect. The end face of the detection sleeve 51 is designed with a top inclined surface 52. This inclined surface design enables the detector 6 to contact the target area at a specific angle, thereby expanding the detection range and improving the comprehensiveness and accuracy of imaging.

[0045] As Figure 6 shown, in order to ensure the precise positioning of the detection sleeve 51 during rotation and movement, the matching component 53 is installed on the surface of the detection sleeve 51. This component closely cooperates with other components to ensure the smoothness of the detection mechanism 5 during operation. The rolling bearing 54 is installed in the middle of the matching component 53. As a key supporting component of the detection mechanism 5, the rolling bearing 54 can significantly reduce the friction during rotation, ensuring that the detection sleeve 51 moves more smoothly and stably. This design not only improves the detection efficiency but also extends the service life of the device, ensuring efficient operation during long-term use.

[0046] The top inclined surface 52 is inclined inwardly, and the detector 6 is arranged at the center of the top inclined surface 52 and is perpendicular to the top inclined surface 52. Setting the top inclined surface 52 to be inclined inwardly and installing the detector 6 at the center of the top inclined surface 52 and perpendicular to the inclined surface have significant advantages in enhancing the detection range and detection accuracy.

[0047] The design of the top inclined surface 52 being inclined inward enables the detector 6 to contact and scan the target area at a wider angle. This inclined angle allows the detector 6 to receive reflected signals from multiple directions, greatly expanding the detection range and helping to obtain more comprehensive detection information. This is particularly important for application scenarios that require all-round scanning of complex structures or irregular surfaces. The detector 6 is arranged perpendicular to the top inclined surface 52, ensuring that the signal emission and reception directions of the detector 6 are consistent with the inclined surface, thereby optimizing the directivity of the detection signal. This design can maximize the utilization rate of ultrasonic or other detection signals, reduce signal loss and interference, and improve the sensitivity and accuracy of detection. The detector 6 can more accurately capture echo signals from different angles, thereby providing a clearer and more detailed imaging effect.

[0048] As Figure 7 shown, the detection sleeve 51 includes a sleeve body 511, a rotating gear ring 512, a rotating gear 513, and a micro brushless motor 514. There are 2 sleeve bodies 511, which are respectively the front and rear parts of the detection sleeve 51. The rotating gear ring 512 is arranged on the bottom surface of the sleeve body 511. The rotating gear 513 is meshed with the rotating gear ring 512. The micro brushless motor 514 is installed inside the other sleeve body 511.

[0049] As Figure 8 shown, the matching component 53 is composed of two connecting blocks 531 and a rotating shaft 532. This design ensures the stability and flexibility of the detection mechanism 5. The two connecting blocks 531 are respectively arranged above and below the rotating sleeve 41. The lower connecting block 531 is directly installed on the upper part of the rotating sleeve 41, playing a role of fixing and supporting. The rotating shaft 532 is installed between the two connecting blocks 531. The connecting blocks 531 achieve smooth rotation through the rotating shaft 532, ensuring that the detection mechanism 5 can move smoothly and accurately during operation, improving the working efficiency and reliability of the overall device.

[0050] In addition to the connecting blocks 531 and the rotating shaft 532, the matching component 53 further includes a rotating shaft 533 and a rolling wheel 534 to enhance the flexibility and stability of the system. The rotating shaft 533 is cleverly arranged on the side of the upper connecting block 531, providing additional support and rotation functions. The rolling wheel 534 is installed on the end face of the rotating shaft 532, making the overall structure move more smoothly during movement. The rolling wheel 534 and the rotating shaft 533 are designed to cooperate closely and can rotate freely in the connecting block 531, ensuring that during the operation of the detection mechanism 5, low-friction and high-efficiency movement can be achieved. This design not only improves the operation fluency of the component, but also effectively reduces wear, extends the service life of the device, and ensures high-precision operation during the detection process.

[0051] As Figure 9As shown, the main body of the rolling bearing 54 is set as a bearing ring 541, and the inner diameter value of the bearing ring 541 is set equal to the outer diameter value of the rotating shaft 532. The inner diameter value of the bearing ring 541 is completely equal to the outer diameter value of the rotating shaft 532, ensuring the precise fit between the bearing and the rotating shaft 532. This precise fit reduces the gap, allowing the rotating shaft 532 to rotate smoothly in the bearing, thereby improving the stability and operation accuracy of the overall system. Precise fit reduces unnecessary friction and wear. The reduction in friction can not only improve the operating efficiency, but also reduce the generation of heat and reduce the energy consumption of the system, thereby improving the overall performance and service life of the equipment. Good fit can prevent relative displacement between the bearing and the rotating shaft 532, and reduce vibration and noise caused by asymmetry or gap. This stability and reliability is particularly important for application scenarios with high precision requirements, and can ensure the stable operation of the equipment in long-term use. Due to the high fit accuracy, the equipment has less wear during operation, thereby reducing the frequency of maintenance and maintenance. Reducing maintenance requirements also reduces the cost of long-term use.

[0052] The bearing ring 541 is provided with a freely movable rolling ball 542, and 60%-70% of the main body of the rolling ball 542 is arranged inside the bearing ring 541. The rolling ball 542 moves freely inside the bearing ring 541, which can significantly reduce the friction resistance between the rotating shaft 532 and the bearing ring 541. Compared with the traditional sliding bearing, the design of the rolling ball 542 reduces the friction force of the contact surface, thereby improving the rotation efficiency and the running stability of the equipment. The rolling ball 542 can evenly distribute the force, reduce the direct friction between the contact surfaces, and reduce the speed of wear. This design of dispersing the force helps to extend the service life of the bearing and the rotating shaft 532, and reduce the frequency of maintenance and replacement. The rolling ball 542 effectively disperses the pressure on the bearing ring 541 and improves the bearing capacity. The design of the rolling ball 542 enables the bearing to withstand a large load and is suitable for high-load or high-speed application scenarios. The movement of the rolling ball 542 inside the bearing ring 541 can provide better stability.

[0053] Since 60%-70% of the main body of the rolling ball 542 is inside the bearing ring 541, the design of this part can ensure that the rolling ball 542 remains stable during movement and is not easy to disengage or lose balance, thereby enhancing the stability of the entire bearing system. The uniform distribution and free movement of the rolling balls 542 can reduce the noise and vibration caused by uneven friction. This design helps to provide a quieter operating environment and reduce the impact of vibration on the equipment and its surrounding environment. Most of the main body of the rolling ball 542 is set inside the bearing ring.

[0054] Inside 541, it helps to enhance the sealing performance and prevent dust and foreign objects from entering the bearing system. This sealing performance can protect the lubricant inside the bearing and further improve the working efficiency and service life of the bearing.

[0055] During the working process of the present invention, the entire ultrasonic probe needs to be used in cooperation with corresponding other instruments (signal line, analysis module, display screen). After the ultrasonic probe is pushed into the designated position, the telescopic rod 2 is opened, and the fixing block 3 helps to fix the protection component 1 in place.

[0056] The driving gear 45 is started under the drive of an external power source, so that the inner ring gear 44 meshing with it rotates, driving the entire rotating sleeve 41 to rotate. The matching component 53 is arranged between the spiral grooves 43. Since the protection component 1 is fixed, the connecting block 531 is fixed in the limit sliding groove 12, the rolling bearing 54 is installed in the horizontal limit groove 13 in a limited manner, the rotating shaft 533 is placed in the clamping groove 14, and the rolling wheel 534 is placed in the rolling groove 15. Thus, the detection mechanism 5 is restricted to move only in the direction of the limit sliding groove 12.

[0057] Since the limit sliding groove 12 is axially arranged, during the rotation of the rotating sleeve 41, the detection sleeve 51 can only perform a linear forward movement under the combined action of the limit sliding groove 12 and the spiral groove 43.

[0058] Furthermore, by controlling the rotation of the front part of the detection sleeve 51, the specific implementation method is that when the driving gear 45 rotates, the micro brushless motor 514 is started simultaneously, driving the rotating gear 513 to rotate, so that the rotating gear ring 512 meshing with it drives the front sleeve body 511 to rotate. Combining with the linear forward movement of the detection sleeve 51, the detector 6 can thus achieve a spiral forward trajectory.

[0059] Therefore, the detector 6 arranged on the top inclined surface 52 can obtain the information in the front and side directions, thereby obtaining the inner shape of the lumen without blind spots, and the complete three-dimensional model diagram of the lumen can be calculated and reconstructed through the scanned information.
