[0025] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of one embodiment of the endoscopic performance testing device of this application. Figure 2 This is a cross-sectional structural diagram of the base corresponding to one embodiment. The aforementioned endoscope performance testing device includes: a base 10, a first support platform 20, a second support platform 30, and a control module 40. Specifically:

[0026] The base 10 is used to support the first support platform 20 and the second support platform 30, and the base 10 includes a first end 11 and a second end 12 disposed opposite to each other.

[0027] The first support platform 20 is used to support the detection target 50. The first support platform 20 is coupled to the first drive component 60, which is used to drive the first support platform 20 to move between the first end 11 and the second end 12. The detection target 50 is provided with a detection pattern.

[0028] The second support platform 30 is disposed on one side of the first end 11 of the base 10. The second support platform 30 is used to support the capsule endoscope 70 to be tested. The endoscope 70 is used to acquire images corresponding to the test target 50. The second support platform 30 is coupled to the second drive assembly 80, which is used to adjust the position of the endoscope 70.

[0029] The control module 40 is coupled to the first drive component 60 and the second drive component 80. The control module 40 is used to simultaneously issue control commands to the first drive component 60 and the second drive component 80 to realize automatic adjustment of the positional relationship between the detection target 50 and the endoscope 70.

[0030] This application proposes an endoscope performance testing device, which includes a first support platform 20 and a second support platform 30 on a base 10. The first support platform 20 supports a detection target 50, and the second support platform 30 supports a capsule endoscope 70. The first support platform 20 is coupled to a first drive assembly 60, and the second support platform 30 is coupled to a second drive assembly 80. A control module 40 sends control commands to the first drive assembly 60 and the second drive assembly 80 respectively to automatically adjust the positional relationship between the detection target 50 and the endoscope 70, enabling the endoscope 70 to acquire more accurate images and facilitating the testing of the endoscope 70's performance based on the acquired images.

[0031] In one embodiment, the first drive assembly 60 includes a first drive unit 61 and a transmission assembly 62, wherein the first drive unit 61 drives the first support platform 20 to move through the transmission assembly 62.

[0032] In one implementation scenario, the transmission assembly 62 includes a transmission screw 621 disposed between a first end 11 and a second end 12, and a first support platform 20 sleeved around the transmission screw 621. A first drive unit 61 drives the transmission screw 621 to rotate, causing the first support platform 20 to move axially between the first end 11 and the second end 12. The first drive unit 61 is a drive motor.

[0033] Specifically, the first support platform 20 includes a first support base 21, on which a through hole matching the aforementioned transmission screw 621 is provided. In practical application, the transmission screw 621 passes through the aforementioned through hole, and the transmission screw 621 is provided with a first thread, while the inner wall of the through hole of the first support base 21 is provided with a second thread matching the aforementioned first thread. During operation, the first drive unit 61 drives the transmission screw 621 to rotate, so that under the action of the cooperation of the first thread and the second thread, the first support platform 20 moves axially between the first end 11 and the second end 12 of the transmission screw 621. For example, when the first drive unit 61 drives the transmission screw 621 to rotate in the positive direction of rotation, the first bearing platform 20 moves along the side closer to the first end 11; when the first drive unit 61 drives the transmission screw 621 to rotate in the opposite direction of rotation, the first bearing platform 20 moves along the side closer to the second end 12. Alternatively, when the first drive unit 61 drives the transmission screw 621 to rotate in the positive direction of rotation, the first bearing platform 20 moves along the side closer to the second end 12; when the first drive unit 61 drives the transmission screw 621 to rotate in the opposite direction of rotation, the first bearing platform 20 moves along the side closer to the first end 11.

[0034] In one embodiment, the transmission assembly 62 further includes a guide shaft 622 disposed between the first end 11 and the second end 12, the guide shaft 622 being parallel to the transmission lead screw 621.

[0035] Specifically, the first support platform 20 includes a first support base 21, which includes a first through hole matching a transmission screw 621 and a second through hole matching a guide shaft 622. The first and second through holes respectively penetrate two oppositely disposed sides of the first support base 21. The transmission screw 621 passes through the first through hole, and the guide shaft 622 passes through the corresponding second through hole. The transmission screw 621 is provided with a first thread, and the inner wall of the first through hole is provided with a second thread matching the first thread.

[0036] In one implementation scenario, the contact surface between the guide shaft 622 and the second through hole is precision machined to form a low-friction pair, so that during the axial movement of the first bearing platform 20, the guide shaft 622 plays a certain role in limiting and guiding the first bearing platform 20, thereby improving the stability of the movement of the first bearing platform 20.

[0037] Additionally, it should be noted that, Figure 1 The diagram only schematically illustrates the structure of the transmission assembly 62, which includes two guide shafts 622. However, in actual applications, the number of guide shafts 622 can be other, such as one or three.

[0038] Optionally, in other embodiments, the transmission assembly 62 may further include a rack, that is, the transmission screw 621 may be replaced by a rack, the first support base 21 is provided with a gear structure that matches the rack, and the first drive unit 61 drives the gear structure on the first support base 21 so that the first support platform 20 drives the detection target 50 to move axially between the first end 11 and the second end 12 through the meshing transmission between the gear structure and the rack.

[0039] Alternatively, the transmission assembly 62 may also include a transmission belt and a drive wheel structure. The first drive unit 61 drives the drive wheel structure to rotate and drives the first bearing platform 20 and the detection target 50 to move axially between the first end 11 and the second end 12 via the transmission belt.

[0040] In one embodiment, the first driving component 60 further includes a second driving unit 63, which is used to drive the detection target 50 to rotate along a central axis perpendicular to the horizontal plane.

[0041] Specifically, the first support platform 20 further includes a support plane 22, which includes an upper surface and a lower surface arranged opposite to each other. The upper surface of the support plane 22 is used to support the detection target 50, and the lower surface of the support plane 22 is provided with the aforementioned second drive unit 63. The second drive unit 63 is an angle adjustment motor, which is connected to the detection target 50 via a rotating shaft. When the angle adjustment motor rotates, it drives the detection target 50 to rotate along a central axis perpendicular to the horizontal plane, thereby adjusting the angle between the plane containing the detection pattern on the detection target 50 and the endoscope 70.

[0042] In some implementation scenarios, the support plane 22 has a third through hole that passes through the upper and lower surfaces. A rotatable rotating shaft is installed in the third through hole. One end of the rotating shaft is fixedly connected to the second drive unit 63, and the other end of the rotating shaft is fixedly connected to the detection target 50, so that the second drive unit 63 drives the detection target 50 to rotate through the rotating shaft.

[0043] In one implementation, please refer to... Figure 1 The endoscope performance testing device proposed in this application also includes at least one distance detection sensor 90, which is disposed on the side surface of the first support platform 20 facing the second support platform. The distance detection sensor 90 is used to detect the target distance between the detection target 50 and the endoscope 70.

[0044] Specifically, a reference distance between the first support platform 20 and the second support platform 30 is measured by a distance detection sensor 90. Since the first positional relationship between the detection target 50 and the first support platform 20 is determined, and the second positional relationship between the endoscope 70 and the second support platform 30 is determined, the target distance between the detection target 50 and the endoscope 70 can be determined based on the first positional relationship, the second positional relationship, and the reference distance.

[0045] In some implementation scenarios, the sensor type of the distance detection sensor 90 can be determined according to the actual application scenario. For example, the distance detection sensor 90 can be at least one of optical ranging sensor, ultrasonic ranging sensor, photoelectric sensor or magnetostrictive sensor.

[0046] Additionally, it should be noted that the distance detection sensor 90 can also be positioned elsewhere. For example, the distance detection sensor can be positioned on the upper surface of the support plane 22 of the first support platform 20; or, the distance detection sensor can also be positioned on the second support platform 30.

[0047] In one embodiment, the second support platform 30 includes a second support base 31 and a sliding sub-platform 32 and a height adjustment sub-platform 33 sequentially disposed on the second support base 31. The endoscope 70 is disposed on the upper surface of the height adjustment sub-platform 33, and the orthographic projection of the height adjustment sub-platform 33 onto the sliding sub-platform 32 at least partially overlaps with the sliding sub-platform 32.

[0048] The second drive assembly 80 includes a third drive unit 81 coupled to the sliding sub-platform 32 and a fourth drive unit 82 coupled to the height adjustment sub-platform 33. The third drive unit 81 is used to drive the sliding sub-platform 32 to move along a first direction, and the fourth drive unit 82 is used to drive the height adjustment sub-platform 33 to move along a second direction. The first direction is parallel to the horizontal plane and perpendicular to the extension direction of the first end 11 and the second end 12, and the second direction is perpendicular to the horizontal plane.

[0049] Specifically, in the direction perpendicular to the horizontal plane, the height adjustment sub-platform 33 is disposed on the sliding sub-platform 32. The third drive unit 81 is a drive motor, which is fixedly disposed on the second support base 31. The sliding sub-platform 32 and the third drive unit 81 are connected by a lead screw. The operation of the third drive unit 81 drives the lead screw to rotate, causing the sliding sub-platform 32 to move along the first direction, thereby adjusting the position of the endoscope 70 in the first direction. The fourth drive unit 82 includes a fixed end and a retractable end disposed opposite to each other. The fourth drive unit 82 is disposed between the sliding sub-platform 32 and the height adjustment sub-platform 33. The fixed end of the fourth drive unit 82 is fixed to the upper surface of the sliding sub-platform 32, and the retractable end of the fourth drive unit 82 is fixed to the lower surface of the height adjustment sub-platform 33. The operation of the fourth drive unit 82 adjusts the height of the height adjustment sub-platform 33 and the endoscope 70 in the second direction. The fourth drive unit 82 is a telescopic motor, a hydraulic cylinder, or a pneumatic cylinder.

[0050] In some implementation scenarios, please refer to Figure 3 , Figure 3 This is a cross-sectional structural schematic diagram of the sliding sub-platform according to one embodiment of this application. To improve the stability of the horizontal position adjustment of the endoscope 70, a sliding track is provided on the upper surface of the second support base 31, and the third drive unit 81 controls the sliding sub-platform 32 to slide along the sliding track. Specifically, the sliding sub-platform 32 includes a protrusion 321, and a sliding track matching the protrusion 321 is provided on the upper surface of the second support base 31. The sliding track extends along a first direction, and at least a portion of the protrusion 321 is disposed within the sliding track, so that the sliding track provides a certain limiting effect on the protrusion 321.

[0051] In some implementation scenarios, in order to improve the stability of the vertical position adjustment of the endoscope 70, at least one guide post is provided on the upper surface of the sliding sub-platform 32, and a through hole is provided on the height adjustment sub-platform 33. The through hole on the height adjustment sub-platform 33 matches the guide post, so that the guide post plays a certain limiting role for the height adjustment sub-platform 33 during the movement along the second direction.

[0052] In one implementation, please refer to Figure 4 , Figure 4 This is a cross-sectional structural diagram of the second support platform according to another embodiment of this application. The second support platform 30 may also include a second support base 31 and a height adjustment sub-platform 33 and a sliding sub-platform 32 sequentially disposed on the second support base 31. The endoscope 70 is disposed on the upper surface of the sliding sub-platform 32, and the orthographic projection of the sliding sub-platform 32 onto the height adjustment sub-platform 33 at least partially overlaps with the height adjustment sub-platform 33.

[0053] In one implementation, please refer to... Figure 1The upper surface of the height adjustment sub-platform 33 is provided with a clamping assembly 100. The clamping assembly 100 is provided with a limiting screw on its side. Under the action of the limiting screw, the clamping assembly 100 is used to fix the endoscope 70 to be tested, so as to improve the stability of the endoscope 70.

[0054] In one embodiment, the control module 40 includes a transmission link 41 and a control link 42. The transmission link 41 is coupled to the distance detection sensor 90 and is used to acquire data detected by the distance detection sensor 90. The control link 42 is coupled to the first drive component 60 and the second drive component 80. The control module 40 is used to send control commands to the first drive component 60 and the second drive component 80 through the control link 42 to adjust the positional relationship between the endoscope 70 and the detection target 50. The transmission link 41 and the control link 42 can be a USB line, a serial port line, a parallel port line, or an I / O line. 2 Wired transmission lines such as C-line or SPI line.

[0055] In some implementation scenarios, the transmission link 41 is coupled to the distance detection sensor 90, so that the control module 40 can obtain the reference distance between the first support platform 20 and the second support platform 30 collected by the distance detection sensor 90 through the transmission link 41. Based on the reference distance between the first support platform 20 and the second support platform 30, the first positional relationship between the detection target 50 and the first support platform 20, and the second positional relationship between the endoscope 70 and the second support platform 30, the control module 40 determines the target distance between the detection target 50 and the endoscope 70. Further, based on the target distance, the control module 40 generates a first control command for controlling the first drive component 60 and a second control command for controlling the second drive component 80, and sends the first control command to the first drive component 60 and the second control command to the second drive component 80 through the control link 42.

[0056] In some implementation scenarios, the control link 42 is also used to transmit the operating data of the corresponding drive component to the control module 40, so that the control module 40 determines the current positional relationship between the endoscope 70 and the detection target 50 in the current state based on the operating data of the drive component and the reference distance collected by the distance detection sensor 90, thereby generating more accurate control commands and improving the accuracy of position adjustment between the endoscope 70 and the detection target 50. Specifically, each drive unit in the first drive component 60 and the second drive component 80 is provided with a corresponding status detection sensor, which is used to collect the operating data of the corresponding drive unit.

[0057] In some implementation scenarios, the control module 40 can also obtain the operating data corresponding to the first drive component 60 and the second drive component 80 respectively through the control link 42, so that the control module 40 can determine the specific positions of the first support platform 20 and the second support platform 30 on the base 10 based only on the operating data, thereby determining the positional relationship between the endoscope 70 and the detection target 50.

[0058] In one embodiment, the control module 40 further includes a wireless communication submodule, which is coupled to the distance detection sensor 90, the first driving component 60, and the second driving component 80. This allows the control module 40 to acquire data detected by the distance detection sensor 90 and corresponding operating data from the first driving component 60 and the second driving component 80. Furthermore, the control module 40 sends corresponding control commands to the first driving component 60 and the second driving component 80 via the wireless communication submodule. The wireless communication submodule can be a Bluetooth module or a WiFi module, etc.

[0059] In one embodiment, the control module 40 is coupled to the endoscope 70. During the detection process, the control module 40 acquires images captured by the endoscope 70, including the detection pattern on the detection target 50. After acquiring the acquired images, the control module 40 combines the acquired images with the positional relationship between the endoscope 70 and the detection target 50 to perform performance analysis on the endoscope 70, thereby generating a performance detection result corresponding to the endoscope 70. Since the control module 40 can automatically control the first drive component 60 and the second drive component 80 and automatically generate performance detection results, the accuracy and efficiency of performance detection of the endoscope 70 are greatly improved. The control module 40 and the endoscope 70 can communicate via wired or wireless transmission.

[0060] In one embodiment, the control module 40 further includes a display screen. The display screen is used to display the operating status of at least one of the distance detection sensor 90, the first drive assembly 60, the second drive assembly 80, and the endoscope 70.

[0061] In some implementation scenarios, the control module 40 is used to receive selection commands triggered by the user in response to content displayed on the screen, and to display detailed operating data of the device or component corresponding to the selection command. The control module 40 may be connected to an external device, such as a mouse or keyboard, through which the user triggers the selection command; alternatively, the display screen of the control module 40 may have a touchscreen function, allowing the user to trigger the selection command by touching a corresponding area on the screen.

[0062] In one embodiment, the control module 40 further includes a power supply component, which supplies power to the control module 40, the distance detection sensor 90 coupled to the control module 40, the first drive component 60, and the second drive component 80. The power supply component can be a battery built into the control module 40; alternatively, it can be a power connection cable, which connects to an external power source to supply power to the control module 40.

[0063] In one embodiment, the first drive component 60 and the second drive component 80 mentioned in any of the above embodiments of this application are used to cooperate with each other to adjust the positional relationship between the endoscope 70 and the detection target 50, and the different drive units in the first drive component 60 and the second drive component 80 can also be combined with each other.

[0064] In some implementation scenarios, the first drive assembly 60 may only include the first drive unit 61 and the transmission assembly 62. The first drive unit 61 and the transmission assembly 62 enable the first support platform 20 to drive the detection target 50 to move axially between the first end 11 and the second end 12. That is, the first drive assembly 60 may not include the second drive unit 63. Furthermore, in addition to the third drive unit 81 and the fourth drive unit 82, the second drive assembly 80 may also include a rotary drive unit coupled to the clamping assembly 100. The rotary drive unit controls the clamping assembly 100 to rotate along a central axis perpendicular to the horizontal plane to adjust the angle between the endoscope 70 and the detection target 50. The specific structure and arrangement of the rotary drive unit in the second drive assembly 80 can be referred to the specific structure and arrangement of the second drive unit 63 in the corresponding embodiments described above, and will not be elaborated further here.

[0065] In one embodiment, the endoscope performance testing device proposed in this application can also be used for performance testing of conventional electronic endoscopes. A conventional electronic endoscope includes a flexible tube and a head end disposed at one end of the flexible tube. The head end includes key components such as an image sensor. The head end of the conventional electronic endoscope is fixed by a clamping assembly 100 so that the image sensor at the head end faces the detection target 50 and can acquire an image including the detection pattern on the detection target 50. The control module 40 acquires the image acquired by the image sensor at the head end and tests the performance of the conventional electronic endoscope based on the image.

[0066] In some implementation scenarios, to improve the efficiency of performance testing for different types of endoscopes, the endoscope performance testing device proposed in this application includes a replaceable clamping assembly 100. When performing performance testing on a capsule endoscope, a clamping assembly 100 matching the capsule endoscope is set at a corresponding position on the second support platform 30, and the capsule endoscope is fixed using the clamping assembly 100. Alternatively, when performing performance testing on a conventional electronic endoscope, a clamping assembly 100 matching the conventional electronic endoscope is set at a corresponding position on the second support platform 30, and the conventional electronic endoscope is fixed using the clamping assembly 100.
