Description

Technical Field

[0001] The present disclosure relates to the technical field of endoscope testing, and particularly to an endoscope testing platform. Background Art

[0002] With the development of endoscope technology, more and more endoscopes are used clinically as medical devices. Doctors observe the situation of the surgical site through the connected display device during minimally invasive surgery. In clinical use, different specifications of endoscopes are required for different usage scenarios. And 3D endoscopes provide stereoscopic images through binocular lenses and cameras, enabling doctors to observe the surgical site more stereoscopically and realistically.

[0003] During the production of 3D endoscopes, it is necessary to perform matching and correction on the left and right path images so that the ideal 3D effect can be produced on the endoscope rod. Currently, the main testing platforms for endoscopes include endoscopes, fixing fixtures, test cards, and backlights. The endoscope is fixed on the fixture, and the handle is rotated to capture the test card on the backlight, and finally, correction is performed through an algorithm. However, in the existing endoscope testing platform, the endoscope cannot read images in different spaces, resulting in deviation in the correction effect of the left and right path images. Summary of the Utility Model

[0004] Based on this, in view of the above problems, it is necessary to provide an endoscope testing platform.

[0005] An embodiment of the present disclosure provides an endoscope testing platform, which includes a base, an adjustment slide table assembly, a fixture, and a testing assembly; the base is arranged horizontally; the adjustment slide table assembly is connected to the base, and the adjustment slide table assembly includes a vertical slide table, a horizontal slide table, and a rotary slide table connected in sequence along the vertical direction. The rotary slide table has a rotation axis along the horizontal direction, and the vertical slide table is connected to the base; the fixture is arranged on one side of the rotary slide table, and the fixture is used to clamp the endoscope rod so that the light output path of the endoscope rod is along the horizontal direction; the testing assembly is connected to the base, and the testing assembly is located on the other side of the rotary slide table. The testing assembly includes a backlight and a multi-angle test card board. The backlight is arranged vertically, and the multi-angle test card board is located between the backlight and the rotary slide table; the multi-angle test card board includes a bottom plate and at least one side plate connected to the bottom plate, and an obtuse angle is formed between the test surface of the bottom plate and the test surface of the side plate.

[0006] In the endoscope testing platform provided by the embodiment of the present disclosure, the bottom plate and at least one side plate are connected to form a multi-angle test card board. The fixture, in cooperation with the adjustment slide table assembly, can drive the endoscope rod to move along the horizontal and vertical directions and rotate around the rotation axis, so that the binocular light paths of the endoscope respectively read the patterns of the multi-angle test card board at different angles in different spaces. After being imported into the algorithm for processing, distortion correction is performed on the left and right path images, making the effects of the left and right path images consistent, and increasing the test accuracy of the endoscope testing platform and the versatility of the testing platform.

[0007] In some embodiments, the bottom plate has a plurality of side edges, and each side edge is connected to a side plate.

[0008] With such a setting, different numbers of side edges of the bottom plate result in different numbers of connected side plates, enriching the types of multi-angle test cards, facilitating the reading of patterns of different multi-angle test cards for the left and right optical paths inside the mirror rod, being beneficial to the correction of the 3D image effect of the endoscope, and increasing the test accuracy of the endoscope test platform and the versatility of the test platform.

[0009] In some embodiments, the fixture has a clamping groove that penetrates the fixture, and the clamping groove is used for clamping the mirror rod.

[0010] With such a setting, the arrangement of the clamping groove is beneficial to clamping the mirror rod and ensuring the position stability when the mirror rod rotates.

[0011] In some embodiments, the rotary stage is provided with a through hole, and the rotation axis is the central axis of the through hole; one end of the fixture close to the rotary stage is a protrusion, and the protrusion is snap-fitted into the through hole so that the clamping groove communicates with the through hole, and the rotary stage drives the fixture to rotate around the rotation axis.

[0012] With such a setting, the protrusion being snap-fitted into the through hole makes the fixture not easily detached from the rotary stage, ensuring that the rotary stage and the fixture can rotate synchronously around the rotation axis.

[0013] In some embodiments, the adjustment stage assembly further includes a stage fixing member, the lower end of the stage fixing member is connected to the horizontal stage; the stage fixing member is provided with a first opening that communicates with the through hole, and the rotary stage is connected to the stage fixing member and rotates relative to the stage fixing member.

[0014] With such a setting, the stage fixing member makes the position of the rotary stage relative to the horizontal stage not change, ensuring that the horizontal distance between the rotary stage and the multi-angle test card remains unchanged when the rotary stage rotates. The first opening ensures that the light output path of the mirror rod can reach the multi-angle test card in the horizontal direction.

[0015] In some embodiments, the horizontal stage includes a slide rail, a slider, a screw rod, and a first rotating handle. The slide rail extends in the horizontal direction, the screw rod passes through the slider so that the slider is movably connected to the slide rail, one end of the screw rod is connected to the first rotating handle, and the first rotating handle is used to drive the screw rod to drive the slider to move horizontally relative to the slide rail; the lower end of the stage fixing member is fixed to the slider.

[0016] With such a setting, it is convenient for the mirror rod to approach or move away from the multi-angle test card in the horizontal direction, meeting the requirement of the mirror rod to read all the patterns on the multi-angle test card. The first rotating handle facilitates manual operation to control the moving distance of the slider. The screw rod drives the slider to move smoothly and with high movement accuracy, increasing the test accuracy.

[0017] In some of these embodiments, the vertical slide includes a linkage mechanism, a movable rod, and a second rotating handle. The linkage mechanism includes a lower end plate, intersecting linkages, and an upper end plate that are connected in sequence. The upper end plate is connected to the slide rail, the lower end plate is fixed to the base, the movable rod is connected to the linkages and to the second rotating handle, and the second rotating handle is used to drive the movable rod to rotate so as to drive the linkages to move in the vertical direction.

[0018] With such an arrangement, the second rotating handle drives the movable rod to rotate, and the movable rod drives the intersecting linkages to rise or fall in the vertical direction. The linkage mechanism has a simple structure and operates smoothly. The second rotating handle is convenient for manual operation, increasing the accuracy of the test.

[0019] In some of these embodiments, the test assembly further includes a first fixing member disposed in the vertical direction. The lower end of the first fixing member is fixed to the base, the upper end of the first fixing member is connected to the multi-angle test card, and a second opening is formed at the upper end of the first fixing member, and the second opening corresponds to the multi-angle test card plate.

[0020] With such an arrangement, the first fixing member ensures that the position of the multi-angle test card plate relative to the base does not change. At the same time, it is convenient for the left and right optical paths in the mirror rod to read all the patterns of the multi-angle test card plate through the second opening, increasing the accuracy of the test.

[0021] In some of these embodiments, the test assembly further includes a second fixing member disposed in the vertical direction. The lower end of the second fixing member is fixed to the base, and the upper end of the second fixing member is connected to the backlight.

[0022] With such an arrangement, the second fixing member cooperates with the first fixing member to ensure that the distance between the backlight and the multi-angle test card plate remains unchanged, reducing the influence of the test assembly on the test result and improving the accuracy of the test.

[0023] In some of these embodiments, the adjustment slide assembly further includes a light shield. The adjustment slide assembly is located between the fixture and the light shield. The light shield is fixed to the base and forms an accommodation space with the base, and the test assembly is located inside the accommodation space.

[0024] With such an arrangement, the light shield treats external light pollution, reduces the influence of external light sources on the test, and increases the accuracy of the test. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Combined with Figure 2, an endoscopic test platform 10 is provided in an embodiment of the present disclosure. The endoscopic test platform 10 includes a base 1, an adjustment slide assembly 2, a fixture 3, and a test assembly 4. The base 1 is arranged in the horizontal direction. Exemplarily, the adjustment slide assembly 2, the fixture 3, and the test assembly 4 are all connected to the base 1. Exemplarily, the fixture 3 is arranged on one side of the adjustment slide assembly 2, and the fixture 3 is used to clamp the lens rod 201 of the endoscope 20 so that the light-emitting path of the lens rod 201 remains horizontal. The test assembly 4 is fixed to the base 1 and is located on the other side of the adjustment slide assembly 2. Exemplarily, the fixture 3, the adjustment slide assembly 2, and the test assembly 4 are arranged in sequence along the horizontal direction.

[0038] The adjustment slide assembly 2 includes a vertical slide 22, a horizontal slide 21, and a rotary slide 23 that are connected in sequence along the vertical direction. The vertical slide 22 is connected to the base 1, and the rotary slide 23 has a horizontal rotation axis. Exemplarily, the vertical slide 22 is located above the base 1 and moves up and down relative to the base 1; the horizontal slide 21 is located above the vertical slide 22 and moves horizontally relative to the vertical slide 22; the rotary slide 23 is located above the horizontal slide 21 and rotates around the rotation axis. Exemplarily, the direction of the rotation axis is the horizontal direction, the horizontal direction is the left-right direction, and the vertical direction is the up-down direction.

[0039] The fixture 3 is connected to one side of the rotary slide 23, and the fixture 3 is used to clamp the lens rod 201 of the endoscope 20. The fixture 3 can clamp the lens rod 201 at different angles so that the light-emitting path of the lens rod 201 is along the horizontal direction. Exemplarily, the fixture 3 is located on the left side of the rotary slide 23, and the endoscope 20 is located on the left side of the fixture 3. The lens rod 201 is a 0° lens rod and can be clamped horizontally by the fixture 3. The lens rod 201 is a 30° lens rod and can be clamped by the fixture 3 with a downward or upward inclination.

[0040] The test assembly 4 is located on the other side of the rotary slide 23. Exemplarily, the test assembly 4 is located on the right side of the rotary slide 23. The test assembly 4 includes a backlight 42 and a multi-angle test card 41. The backlight 42 is arranged vertically, and the multi-angle test card 41 is located between the backlight 42 and the rotary slide 23. The multi-angle test card 41 includes a bottom plate 411 and at least one side plate 412 connected to the bottom plate 411. An obtuse angle is formed between the test surface of the bottom plate 411 and the test surface of the side plate 412. Exemplarily, the fixture 3, the rotary slide 23, at least one side plate 412, the bottom plate 411, and the backlight 42 are arranged in sequence from left to right along the horizontal direction. The test surface of the bottom plate 411 is located on the left side of the bottom plate 411. The test surface of the bottom plate 411 faces the horizontal light-emitting path of the lens rod 201, and patterns are provided on the test surface for testing the optical path effect. The test surface of the side plate 412 is located on the left side of the side plate 412. The test surface of the side plate 412 is inclined relative to the horizontal light-emitting path of the lens rod 201, and patterns are provided on the test surface for testing the optical path effect.

[0041] The endoscope test platform 10 provided by the embodiments of the present disclosure can set the rod 201 of the endoscope 20 at different angles on the fixture 3. The fixture 3 cooperates with the adjustment slide assembly 2 to drive the rod 201 of the endoscope 20 to move horizontally and vertically and rotate around the rotation axis, so that the optical path of the endoscope 20 can read all the patterns on the bottom plate 411 and at least one side plate 412 at different positions and different angles. It can be understood that the endoscope 20 can be a binocular optical path or a monocular optical path, and the endoscope test platform 10 also enables the optical path of the endoscope 20 to read all the patterns on the bottom plate 411 and at least one side plate 412 at different positions and different angles.

[0042] The endoscope test platform 10 provided by the embodiments of the present disclosure can keep the binocular optical path of the endoscope 20 horizontal and read the patterns of the multi-angle test card board 41 in different spaces at different positions. After subsequent algorithm processing, the images of the binocular optical path can be corrected for distortion, so that the image effects of the binocular optical path are consistent, increasing the test accuracy and versatility of the endoscope test platform 10.

[0043] Exemplarily, the fixture 3 can be replaced. By replacing the fixture 3, the rods 201 at more angles can be clamped to ensure that the light output path of the rod 201 is horizontal.

[0044] Exemplarily, the area of the backlight 42 is larger than the area of the bottom plate 411.

[0045] Exemplarily, the bottom plate 411 is circular, and there is only one side plate 412 surrounding the edge of the bottom plate 411.

[0046] Exemplarily, the projection of the bottom plate 411 in the left-right direction is square, and there are two side plates 412. One side plate 412 is connected to the upper side and the lower side of the bottom plate 411 respectively; the projection of the side plate 412 in the up-down direction is trapezoidal.

[0047] Exemplarily, the included angle between the side plate 412 and the bottom plate 411 ranges from 90° to 180°. For example, the included angle between the side plate 412 and the bottom plate 411 is 100°, 135° or 150°. It can be understood that the included angle ranges of multiple side plates 412 and the bottom plate 411 are the same.

[0048] In other embodiments, the horizontal slide 21 and the vertical slide 22 are located on the base 1 and move horizontally relative to the base 1; the vertical slide 22 is located on the horizontal slide 21 and moves up and down relative to the horizontal slide 21; the rotary slide 23 is located on the vertical slide 22 and rotates around the rotation axis.

[0049] Reference Figure 1 and Figure 2In some embodiments, the bottom plate 411 has a plurality of side edges, and each side edge is connected to a side plate 412 .

[0050] With such a configuration, the different numbers of sides of the bottom plate 411 result in different numbers of connected side plates 412, thereby enriching the types of multi-angle test card plates 41, facilitating the binocular path within the mirror rod 201 to read patterns of different multi-angle test card plates 41, and being beneficial to the correction of the 3D image effect of the endoscope 20, thereby increasing the test accuracy of the endoscope test platform 10 and the versatility of the test platform.

[0051] Exemplarily, the projection of the bottom plate 411 along the horizontal direction is a square, there are four side plates 412 , and the four side plates 412 are respectively connected to the four sides of the bottom plate 411 .

[0052] Exemplarily, the size and shape of the bottom plate 411 can be changed. The shape of the bottom plate 411 projected in the horizontal direction can also be a triangle, a rhombus, a hexagon, etc. Each side of the bottom plate 411 is connected to a side plate 412 .

[0053] In some embodiments, the clamp 3 has a clamping groove 31 , which passes through the clamp 3 and is used to clamp the mirror rod 201 .

[0054] In this way, the clamping groove 31 is arranged to help clamp the mirror rod 201 and ensure the position stability of the mirror rod 201 when rotating.

[0055] Exemplarily, the clamping groove 31 horizontally passes through the fixture 3 from left to right. In other embodiments, the clamping groove 31 can also be arranged in different directions to ensure that the light emitting path of the mirror rod 201 is in the horizontal direction.

[0056] For example, the clamping groove 31 can clamp the endoscope 20 with a 0° or 30° scope shaft 201 .

[0057] refer to Figure 1 and Figure 2 In some embodiments, a through hole 231 is formed in the rotating slide 23, and the rotation axis is the central axis of the through hole 231; one end of the clamp 3 close to the rotating slide 23 is a protrusion 32, and the protrusion 32 is clamped in the through hole 231 so that the clamping groove 31 is connected to the through hole 231, and the rotating slide 23 drives the clamp 3 to rotate around the rotation axis.

[0058] With such arrangement, the protrusion 32 is engaged with the through hole 231 so that the clamp 3 is not easily separated from the rotating slide 23 , thereby ensuring that the rotating slide 23 and the clamp 3 can rotate synchronously around the rotation axis.

[0059] Exemplarily, the protrusion 32 is in the shape of a cuboid.

[0060] Exemplarily, manually operate the rotary slide table 23 to rotate about the rotation axis.

[0061] In other embodiments, the projection of the through hole 231 in the left - right direction can be quadrilateral, triangular or other shapes. The shape of the protrusion 32 corresponds to the shape of the through hole 231.

[0062] Refer to Figure 1 and Figure 2 In some embodiments, the adjustment slide assembly 2 further includes a slide fixing member 24. The lower end of the slide fixing member 24 is connected to the horizontal slide table 21. The slide fixing member 24 is provided with a first opening 241 which communicates with the through hole 231. The rotary slide table 23 is connected to the slide fixing member 24 and rotates relative to the slide fixing member 24. Exemplarily, manually operate the rotary slide table 23 to perform a rotation action.

[0063] With such a setting, the slide fixing member 24 keeps the position of the rotary slide table 23 relative to the horizontal slide table 21 unchanged, ensuring that the horizontal distance between the rotary slide table 23 and the multi - angle test card 41 remains unchanged when the rotary slide table 23 rotates. The first opening 241 ensures that the light - emitting path of the mirror rod 201 can reach the multi - angle test card 41 in the horizontal direction.

[0064] Exemplarily, the lower end of the slide fixing member 24 is bolt - connected to the horizontal slide table 21.

[0065] Refer to Figure 3 In some embodiments, the horizontal slide table 21 includes a slide rail 211, a slider 212, a screw rod 213 and a first rotary handle 214. The slide rail 211 extends in the horizontal direction. The screw rod 213 passes through the slider 212 so that the slider 212 is movably connected to the slide rail 211. One end of the screw rod 213 is connected to the first rotary handle 214. The first rotary handle 214 is used to drive the screw rod 213 to drive the slider 212 to move relative to the slide rail 211 in the horizontal direction. The lower end of the slide fixing member 24 is fixed to the slider 212.

[0066] Exemplarily, the screw rod 213 is arranged parallel to the slide rail 211. The first rotary handle 214 drives the screw rod 213 to make the slider 212 move away from or close to the test assembly 4 in the left - right direction.

[0067] With such a setting, it is convenient for the mirror rod 201 to approach or move away from the multi - angle test card 41 in the horizontal direction, meeting the requirement that the mirror rod 201 reads all the patterns on the multi - angle test card 41. The first rotary handle 214 facilitates manual operation to control the moving distance of the slider 212. The screw rod 213 drives the slider 212 to move smoothly and with high movement accuracy, increasing the test accuracy.

[0068] Refer to Figure 4, in some embodiments, the vertical slide 22 includes a linkage mechanism 221, a movable rod 223, and a second rotary handle 222. The linkage mechanism 221 includes a lower end plate 2211, intersecting linkages 2212, and an upper end plate 2213 that are connected in sequence. The upper end plate 2213 is connected to the slide rail 211, the lower end plate 2211 is fixed to the base 1, the movable rod 223 is connected to the linkages 2212 and to the second rotary handle 222. The second rotary handle 222 is used to drive the rotation of the movable rod 223 so as to drive the linkages 2212 to move in the vertical direction.

[0069] With such an arrangement, the second rotary handle 222 drives the rotation of the movable rod 223, and the movable rod 223 drives the intersecting linkages 2212 to rise or fall in the vertical direction. The linkage mechanism 221 has a simple structure and operates stably. The second rotary handle 222 is convenient for manual operation, increasing the accuracy of the test.

[0070] Exemplarily, the middle parts of the two linkages 2212 overlap and intersect. The two ends of the two linkages 2212 are respectively connected to the upper end plate 2213 and the lower end plate 2211. There are two intersecting linkages 2212 on each of the left and right sides of the upper end plate 2213 and the lower end plate 2211.

[0071] Reference Figure 1 and Figure 2 , in some embodiments, the test assembly 4 further includes a first fixing member 43 arranged in the vertical direction. The lower end of the first fixing member 43 is fixed to the base 1, the upper end of the first fixing member 43 is connected to the multi-angle test card 41, and a second opening 431 is formed at the upper end of the first fixing member 43, and the second opening 431 corresponds to the multi-angle test card 41.

[0072] With such an arrangement, the first fixing member 43 ensures that the position of the multi-angle test card 41 relative to the base 1 does not change. At the same time, it is convenient for the left and right optical paths in the mirror rod 201 to read all the patterns of the multi-angle test card 41 through the second opening 431, increasing the accuracy of the test.

[0073] In other embodiments, the first fixing member 43 and the multi-angle test card 41 may be an integral structure.

[0074] Reference Figure 1 and Figure 2 , in some embodiments, the test assembly 4 further includes a second fixing member 44 arranged in the vertical direction. The lower end of the second fixing member 44 is fixed to the base 1, and the upper end of the second fixing member 44 is connected to the backlight 42.

[0075] In other embodiments, the second fixing member 44 and the backlight 42 are an integral structure.

[0076] With such an arrangement, the second fixing member 44 cooperates with the first fixing member 43 to ensure that the distance between the backlight 42 and the multi-angle test card board 41 remains unchanged, reducing the influence of the test assembly 4 on the test results and improving the accuracy of the test.

[0077] Reference Figure 1 And Figure 2 , in some of the embodiments, the adjusting slide assembly 2 further includes a light shielding cover 5. The adjusting slide assembly 2 is located between the fixture 3 and the light shielding cover 5. The light shielding cover 5 is fixed to the base 1 and forms a receiving space with the base 1. The test assembly 4 is located inside the receiving space.

[0078] With such an arrangement, the light shielding cover 5 deals with external light pollution, reduces the influence of external light sources on the test, and increases the accuracy of the test.

[0079] Exemplarily, the light shielding cover 5 is located on the right side of the adjusting slide assembly 2 and has an opening facing left. The light shielding cover 5 can block light pollution from the front side, the rear side, the right side, and the upper side.

[0080] The technical features of the above-disclosed embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
