Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to an ultrasonic detection head with panoramic detection effect. Background Art

[0002] Ultrasonic probes with panoramic detection effects are ultrasonic imaging devices that can provide a wide range of viewing angles and are commonly used in medical diagnosis, industrial inspection and other fields. Its main feature is that it can image with a large viewing angle range, thereby providing more comprehensive detection information. Wide viewing angle: The panoramic ultrasonic probe head uses a multi-array or specific structural design to achieve the transmission and reception of ultrasonic beams in multiple directions, covering a larger area and generating panoramic images. Multi-dimensional imaging: The probe head 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: The probe head with panoramic detection effect is usually equipped with a high-frequency ultrasonic transmitter, which can capture more subtle structural changes and achieve high-resolution imaging. Fast scanning: Due to the large viewing angle range, the panoramic probe head can complete the scanning of a large area in a short time, reducing the detection time. Wide application: In the medical field, the panoramic ultrasonic probe head can be used for comprehensive inspection of the abdomen, heart, musculoskeletal and other parts; in the industrial field, it is suitable for scenes such as material inspection and structural integrity assessment.

[0003] Currently, devices that use a mechanically rotating single working unit (such as IVUS, OCT) or an array phased array (such as ICE) to detect the intraluminal morphology can only obtain lateral information of the catheter. Due to the structural characteristics, there is a large blind spot in the center of the imaging area, so that the corresponding image information results cannot directly guide the use of treatment devices that require a forward field of view.

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

[0005] The technical purpose to be achieved by the present invention is to work in a spiral forward manner with a single detector, and simultaneously obtain data information in front of and to the sides of the target lumen.

[0006] In order to achieve the above technical objectives, 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 protection component is precisely designed and includes a shell, a limit slide, a horizontal limit groove, a snap-in groove and a rolling groove. The shell, as the main body of the protection component, adopts a sleeve-like structure, which can provide comprehensive protection for the internal components. The inner surface of the shell is provided with a limit slide. This design allows the internal components to move along a specific trajectory to ensure that they remain stable during operation. A horizontal limit groove is provided on the side of the limit slide to further limit the horizontal movement range of the component and prevent it from shifting. In order to enhance the stability of the connection, a snap-in groove is provided above the horizontal limit groove to fix the connecting component. A rolling groove is also provided on the outside of the snap-in groove to provide additional support and flexibility to ensure the smooth operation of the detection head during operation.

[0009] The cross-sectional shape of the horizontal limit groove is set to a semicircular shape, and the width of the clamping groove is set to half the width of the rolling groove. The cross-sectional shape of the horizontal limit groove is designed to be semicircular, and the width of the clamping groove is set to half the width of the rolling groove. This design has significant advantages in structural stability and operational flexibility. The horizontal limit groove with a semicircular cross-section can effectively enhance the limiting function. Since the semicircular shape can better match the circular or arc-shaped parts in contact with it, it can provide more stable support and more precise limiting to prevent the parts from unexpected horizontal displacement during sliding. At the same time, the semicircular design can also reduce the friction between the contact surfaces, making the related parts smoother when moving. The width of the clamping groove is set to half 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 connecting parts to prevent them from falling off or loosening, while the wider rolling groove provides more movement space, allowing the internal parts to be adjusted and rolled appropriately. This width ratio design ensures both the stability of the structure and the flexibility and freedom of the components during operation, so that the entire device can maintain efficient operation under complex working conditions.

[0010] The design of the rotating assembly includes a rotating sleeve, a stop ring, a spiral groove, an inner ring tooth and a driving gear, aiming to achieve precise and stable rotational motion. First, the rotating sleeve is installed inside the protective assembly. As the core structure of the rotating assembly, its stability directly affects the operation effect of the entire device. The surface of the sleeve is designed with a spiral groove, which can guide the internal components to rotate or move along a specific trajectory, thereby achieving a complex motion pattern.

[0011] In order 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 limit the lateral movement of the rotating sleeve to avoid affecting the rotation accuracy due to unnecessary displacement. An inner ring gear is also designed on the inside of one end of the rotating sleeve. These gears mesh with other gears inside the device to form a precise gear transmission system. The driving gear installed on the inside of the inner ring gear is matched with the inner ring gear. The function of the driving gear is to transmit power to the rotating sleeve and drive it to rotate according to the set trajectory. The design of the entire rotating assembly ensures smooth and precise rotational motion during operation, improving the overall performance and reliability of the equipment.

[0012] The detection mechanism is composed of a detection sleeve, a top bevel, a matching component and a rolling bearing, and is intended to achieve an efficient detection function. The detection sleeve is installed inside the rotating component. As the core component of the detection mechanism, its stability and accuracy directly affect the detection effect. The end face of the detection sleeve is designed with a top bevel. This bevel 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] In order to ensure that the detection sleeve can be accurately positioned during rotation and movement, the matching component is installed on the surface of the detection sleeve. This component cooperates closely with other components to ensure the stability 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 is smoother and more stable during movement. This design not only improves the detection efficiency, but also extends the service life of the equipment, ensuring that it remains efficient in long-term use.

[0014] The top slope is tilted inwards, and the detector is arranged at the center of the top slope and perpendicular to the top slope. The top slope is tilted inwards, and the detector is installed at the center of the top slope and perpendicular to the slope. This design has significant advantages in improving the detection range and detection accuracy.

[0015] The inward-inclined design of the top bevel enables the detector to contact and scan the target area at a wider angle. This tilt 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 especially important for applications that require all-round scanning of complex structures or irregular surfaces. The detector is set perpendicular to the top bevel, ensuring that the signal transmission and reception direction of the detector is consistent with the bevel, thereby optimizing the directionality of the detection signal. This design can maximize the utilization 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, providing clearer and more detailed imaging effects.

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

[0017] The mating assembly 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, and the lower connecting block is directly installed on the upper part of the detection sleeve to play a role of fixing and supporting. The rotating shaft is installed between the two connecting blocks. The connecting block can realize smooth rotation through the rotating shaft, ensuring that the detection mechanism can move smoothly and accurately during operation, thereby improving the working efficiency and reliability of the overall device.

[0018] In addition to the connection block and the rotating shaft, the mating component further includes a rotating shaft and a rolling wheel to enhance the flexibility and stability of the system. The rotating shaft is cleverly arranged on the side of the upper connection block to provide additional support and rotation functions. The rolling wheel is mounted on the end face of the rotating shaft, making the overall structure more stable during movement. The rolling wheel is designed to fit tightly with the rotating shaft and can rotate freely in the connection block, ensuring low-friction and high-efficiency movement when the detection mechanism is in operation. This design not only improves the smoothness of the component's operation, but also effectively reduces wear and extends the service life of the equipment, while ensuring high-precision operation during the detection process.

[0019] The main body of the rolling bearing is set as a rotating bearing ring, and 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 completely 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 gap, allowing the rotating shaft to rotate smoothly in the rotating 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 rotating bearing and the rotating shaft, 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.

[0020] The bearing ring is provided with freely movable rolling balls, and 60%-70% of the rolling ball body is arranged inside the bearing ring. The rolling balls move freely inside the bearing ring, which can significantly reduce the friction resistance between the rotating shaft and the bearing ring. Compared with traditional sliding bearings, the design of the rolling balls reduces the friction of the contact surface, thereby improving the rotation efficiency and the running stability of the equipment. The rolling balls 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 rolling bearing and the rotating shaft, and reduces the frequency of maintenance and replacement. The rolling balls effectively disperse the pressure on the bearing ring and improve the bearing capacity of the rolling bearing. The design of the rolling balls 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 balls inside the bearing ring can provide better stability. Since 60%-70% of the rolling ball body is inside the bearing ring, this part of the design can ensure that the rolling balls remain stable during movement, are not easy to disengage or unbalance, thereby enhancing the stability of the entire bearing system. The uniform distribution and free movement of the rolling balls can reduce the noise and vibration caused by uneven friction. This design helps provide a quieter operating environment and reduces the impact of vibration on the equipment and its surroundings. The majority of the ball body is set inside the bearing ring, which helps to enhance the seal and prevent dust and foreign matter from entering the bearing system. This seal protects the lubricant inside the bearing, further improving the operating efficiency and service life of the bearing.

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

[0022] 1. The present invention obtains information about the situation in the lumen in front and on the side of the catheter at the same time when only one detector is used. This design significantly optimizes the structure of the ultrasonic detection system and brings many significant advantages. First, by using a transducer working unit to detect 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 high manufacturing and maintenance costs. However, this solution uses a single detector to complete multi-directional detection, effectively simplifies the system design, and reduces the complexity and cost of the equipment. Secondly, reducing the number of signal channels and streamlining the system structure makes 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 range of the catheter. In the field of industrial detection, these spaces can also be used to add more detection modules or optimize the existing detector settings, thereby improving the detection capability of the overall system. This technical solution not only improves the detection efficiency, but also enhances the reliability of the system. Redundant signal channels and complex wiring are reduced, the possibility of signal interference is reduced, and the stability of the system and data accuracy are enhanced. Due to the reduction of signal channels, the noise and interference sources in the system are also reduced accordingly, thereby improving the clarity and accuracy of detection.

[0023] 2. Compared with the existing medical intra-ultrasound imaging solutions, the present invention has significant advantages in obtaining intra-luminal information. Traditional intra-ultrasound systems often face the problem of blind spots in the center of the catheter that cannot be imaged. These blind spots are usually unable to obtain clear images due to the limitations of the position of the detector and the direction of signal propagation, thus affecting the comprehensive understanding of the internal structure of the lumen. However, the present technical solution enables the detector to perform effective imaging in front and on the side of the catheter at the same time, 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 blind spots in the imaging of the central area of ​​the catheter, thereby achieving complete imaging of the entire lumen. This all-round imaging capability not only improves the continuity and clarity of the image, but also enhances the detection and analysis capabilities of abnormal conditions in the lumen, allowing 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 testing, and can provide more accurate evaluation and decision support.

DETAILED DESCRIPTION

[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 and specific implementation methods.

[0038] like Figure 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.

[0039] like Figure 2-3As shown, the protection component 1 is precisely designed and includes a shell 11, a limiting slide 12, a horizontal limiting groove 13, a snap-in groove 14 and a rolling groove 15. The shell 11, as the main body of the protection component 1, adopts a sleeve-like structure, which can provide comprehensive protection for the internal components. The inner surface of the shell 11 is provided with a limiting slide 12. This design allows the internal components to move along a specific trajectory to ensure that they remain stable during operation. A horizontal limiting groove 13 is provided on the side of the limiting slide 12 to further limit the horizontal movement range of the component and prevent it from shifting. In order to enhance the connection stability, a snap-in groove 14 is provided above the horizontal limiting groove 13 for fixing the connecting component. A rolling groove 15 is also provided on the outside of the snap-in groove 14 to provide additional support and flexibility to ensure the smooth operation of the detection head during operation.

[0040] like Figure 3 As shown, the cross-sectional shape of the horizontal limit groove 13 is set to a semicircular shape, and the width value of the clamping groove 14 is set to half the width value of the rolling groove 15. The cross-sectional shape of the horizontal limit groove 13 is designed to be semicircular, and the width value of the clamping groove 14 is set to half the width value of the rolling groove 15. This design has significant advantages in structural stability and operational flexibility. The horizontal limit groove 13 with a semicircular cross-section can effectively enhance the limiting function. Since the semicircular shape can better match the circular or arc-shaped parts in contact with it, it can provide more stable support and more accurate limiting to prevent the parts from unexpected horizontal displacement during the sliding process. At the same time, the semicircular design can also reduce the friction between the contact surfaces, making the related parts smoother when moving. The width of the clamping groove 14 is set to half the width of the rolling groove 15, which helps to optimize the compactness and coordination of the overall structure. The narrower clamping groove 14 can firmly lock the connecting parts to prevent them from falling off or loosening, while the wider rolling groove 15 provides more movement space, allowing the internal parts to be moderately adjusted and rolled. This width ratio design ensures both the stability of the structure and the flexibility and freedom of the components during operation, so that the entire device can maintain efficient operation under complex working conditions.

[0041] like Figure 4 As shown, the design of the rotating assembly 4 includes a rotating sleeve 41, a stop 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, the rotating sleeve 41 is installed inside the protection assembly 1. As the core structure of the rotating assembly 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 the internal components to rotate or move along a specific trajectory, thereby achieving a complex motion mode.

[0042] In order 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 limit the lateral movement of the rotating sleeve 41 to avoid affecting the rotation accuracy due to unnecessary displacement. The inner side surface of one end of the rotating sleeve 41 is also designed with inner ring teeth 44. These gears mesh with other gears inside the device to form a precise gear transmission system. Cooperating with the inner ring teeth 44 is the driving gear 45 installed on its inner side. The function of the driving gear 45 is to transmit power to the rotating sleeve 41 and drive it to rotate according to the set trajectory. The design of the entire rotating assembly 4 ensures that it can provide smooth and precise rotational motion during operation, thereby improving the overall performance and reliability of the equipment.

[0043] like Figure 5 As shown, the detection mechanism 5 is composed of a detection sleeve 51, a top bevel 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 component 4. As the core component of the detection mechanism 5, the detection sleeve 51 is set to two parts, wherein the rear part is used as a power part, and the front part is used as a rotating part. A micro power source (motor) is provided inside the detection sleeve 51 to drive the front part to rotate, and the rotation action control of the detection sleeve 51 is consistent with the driving gear 45, so that the detection sleeve 51 can move forward and rotate at the same time, and realize a spiral forward route. Its stability and accuracy directly affect the detection effect. The end face of the detection sleeve 51 is designed with a top bevel 52. This bevel 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.

[0044] like Figure 6 As shown, in order to ensure that the detection sleeve 51 can be accurately positioned during rotation and movement, a matching component 53 is installed on the surface of the detection sleeve 51. This component cooperates closely with other components to ensure the stability 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 is smoother and more stable during movement. This design not only improves the detection efficiency, but also extends the service life of the equipment, ensuring that it still maintains efficient operation during long-term use.

[0045] The top slope 52 is tilted inwards, and the detector 6 is arranged at the center of the top slope 52 and perpendicular to the top slope 52. The top slope 52 is tilted inwards, and the detector 6 is installed at the center of the top slope 52 and perpendicular to the slope. This design has significant advantages in improving the detection range and detection accuracy.

[0046] The inwardly inclined design of the top bevel 52 enables the detector 6 to contact and scan the target area at a wider angle. This inclination 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 especially important for application scenarios that require all-round scanning of complex structures or irregular surfaces. The detector 6 is arranged perpendicular to the top bevel 52 to ensure that the signal transmission and reception direction of the detector 6 is consistent with the bevel, thereby optimizing the directionality of the detection signal. This design can maximize the utilization 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 clearer and more detailed imaging effects.

[0047] like Figure 7 As 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. The sleeve body 511 is provided with two parts, namely 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 and the rotating gear ring 512 are meshed. The micro brushless motor 514 is installed inside the other sleeve body 511.

[0048] like Figure 8 As shown, the mating assembly 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 at the upper and lower parts of the rotating sleeve 41, and the lower connecting block 531 is directly installed on the upper part of the rotating sleeve 41 to play a role of fixing and supporting. The rotating shaft 532 is installed between the two connecting blocks 531. The connecting block 531 rotates smoothly through the rotating shaft 532, ensuring that the detection mechanism 5 can move smoothly and accurately during operation, thereby improving the working efficiency and reliability of the overall device.

[0049] In addition to the connecting block 531 and the rotating shaft 532, the mating 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 to provide additional support and rotation functions. The rolling wheel 534 is mounted on the end face of the rotating shaft 532, making the overall structure more stable during movement. The rolling wheel 534 is designed to fit tightly with the rotating shaft 533 and can rotate freely in the connecting block 531, ensuring low-friction and high-efficiency movement when the detection mechanism 5 is in operation. This design not only improves the smoothness of the component's operation, but also effectively reduces wear and tear, extends the service life of the equipment, and ensures high-precision operation during the detection process.

[0050] like Fig. 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 533. The inner diameter value of the bearing ring 541 is completely equal to the outer diameter value of the rotating shaft 533, ensuring the precise fit between the bearing and the rotating shaft 533. This precise fit reduces the gap, allowing the rotating shaft 533 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 533, 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.

[0051] 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 533 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 533, 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. 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 arranged inside the bearing ring 541, which helps to enhance the sealing and prevent dust and foreign matter from entering the bearing system. This sealing can protect the lubricant inside the bearing, further improving the working efficiency and service life of the bearing.

[0052] During the working process of the present invention, the entire ultrasonic probe needs to be used in conjunction with other corresponding instruments (signal line, analysis module, display screen). After the ultrasonic probe is pushed into the specified position, the telescopic rod 2 is opened, and the fixing block 3 helps to fix the protection component 1 in place;

[0053] The driving gear 45 is started under the drive of the external power source, so that the inner ring gear 44 meshing with it rotates, driving the entire rotating sleeve 41 to rotate, and 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 limiting slide groove 12, and the rolling bearing 54 is limitedly installed in the horizontal limiting groove 13. The rotating shaft 533 is placed in the clamping groove 14, and the rolling wheel 534 is placed in the rolling groove 15, so that the detection mechanism 5 is limited to move only in the direction of the limiting slide groove 12;

[0054] Since the limiting slide groove 12 is axially arranged, during the rotation of the rotating sleeve 41, the detection sleeve 51 can only move forward in a straight line under the cooperation of the limiting slide groove 12 and the spiral groove 43;

[0055] Then, 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 at the same time, driving the rotating gear 513 to rotate, so that the rotating gear ring 512 meshing with it drives the sleeve body 511 in the front to rotate, and cooperates with the detection sleeve 51 to move forward linearly, thereby realizing the spiral forward trajectory of the detector 6;

[0056] Therefore, the detector 6 arranged on the top slope 52 can obtain the information from the front and the side, so as to obtain the internal morphology of the lumen without blind spots, and the complete three-dimensional model diagram of the lumen can be calculated and reconstructed by scanning the information.
