Abstract
Description
Technical Field
[0001] This utility model relates to the field of hard mirror testing technology, specifically a hard mirror multi-target testing platform. Background Technology
[0002] Rigid endoscopes (such as laparoscopes and arthroscopes) are important medical endoscopic instruments, and their imaging quality directly affects clinical diagnosis and surgical outcomes. Existing testing platforms are mostly designed with a single fixed target, typically enabling testing from only one angle. They cannot automatically switch targets, and angles and positions require manual adjustment, resulting in insufficient precision, high manpower and resource consumption, and low testing efficiency. This makes it difficult to meet the comprehensive performance evaluation needs for efficient testing from multiple angles, positions, and parameters. Utility Model Content
[0003] To address the shortcomings of existing technologies, this invention provides a multi-target testing platform for rigid microscopes. A rotating platform allows for switching between test targets, supporting multiple targets and various testing methods. Each target is equipped with an independent rotation mechanism to facilitate testing the imaging of the rigid microscope at different angles. Vertical lifting and linear displacement of the targets are achieved through lifting and moving mechanisms, adapting to various testing needs at different positions of different rigid microscopes. This significantly improves testing efficiency, avoids repeated adjustments to the testing device, and effectively solves the problems of low efficiency and limited simulation of working conditions in traditional rigid microscope testing. It provides a more scientific and efficient testing method for evaluating the performance of rigid microscopes.
[0004] To achieve the above objectives, this utility model employs the following technical solution:
[0005] A rigid microscope multi-target testing platform includes:
[0006] Rotating platform;
[0007] A rotating mechanism for driving the rotating platform to rotate about an axis perpendicular to its plane;
[0008] Multiple targets are set on a rotating platform and arranged at intervals along the circumference of the rotating platform;
[0009] Multiple target rotation mechanisms, each of which independently drives the corresponding target to rotate around its own axis;
[0010] At least one lifting mechanism is provided on the rotating platform for driving the corresponding target and its target rotation mechanism to move in the vertical direction;
[0011] At least one moving mechanism is disposed on the corresponding target rotation mechanism for controlling the linear movement of the corresponding target.
[0012] The rotating mechanism includes a first rotary motor, a first drive gear connected to the output end of the first rotary motor, and a first driven gear meshing with the first drive gear. The first driven gear is connected to the rotating platform.
[0013] There are four targets, which are evenly distributed along the circumference of the rotating platform.
[0014] A first target, a second target, a third target, and a fourth target are sequentially arranged along the circumference of the rotating platform. The first and third targets are adjusted in the same way, and their corresponding target rotation mechanisms are mounted on the rotating platform via support seats. The second and fourth targets are adjusted in the same way, and their corresponding target rotation mechanisms are mounted on the sliding seats of the lifting mechanism. A moving mechanism is mounted on the target rotation mechanism, and the second and fourth targets are mounted on the sliding seats of the moving mechanism.
[0015] The plurality of targets include one or more of the following: resolution test target, distortion test target, depth of field test target, transmittance and uniformity test target, and color reproduction test target.
[0016] The aforementioned rigid mirror multi-target testing platform also includes a control system, which is electrically connected to the rotation mechanism, the target rotation mechanism, the lifting mechanism, and the moving mechanism.
[0017] The aforementioned rigid mirror multi-target testing platform further includes a position sensor for real-time feedback and control of the target position, and the position sensor is connected to the control system.
[0018] Compared with existing technologies, the advantages of this invention are as follows: This invention integrates multiple targets distributed along the circumference through a rotating platform. The rotating platform is controlled by a rotating mechanism, allowing targets at different positions to rotate to the corresponding orientation of the rigid endoscope under test, thus completing tests for different rigid endoscope requirements. Each target is equipped with an independent rotating mechanism to facilitate testing the imaging of the rigid endoscope at different angles and to simulate the imaging effect under rotation, more realistically reflecting the dynamic performance of the rigid endoscope in actual surgery. Vertical lifting and linear displacement of the targets are achieved through lifting and moving mechanisms to adapt to various testing needs at different positions of different rigid endoscopes. It can also accurately simulate the relative positional changes of instruments and tissues during surgery, improving the comprehensiveness and accuracy of the test. This invention significantly improves testing efficiency through multi-target collaborative testing, avoids repeated adjustments to the testing device, and effectively solves the problems of low efficiency and limited simulation of working conditions in traditional rigid endoscope testing, providing a more scientific and efficient testing method for rigid endoscope performance evaluation.

[0030] like Figures 1-8 As shown, this utility model provides a multi-target testing platform for rigid microscopes, including a rotating platform 1, a rotating mechanism 2 for driving the rotating platform 1 to rotate about an axis perpendicular to its plane, and multiple targets 3, multiple target rotation mechanisms 4, at least one lifting mechanism 5, and at least one moving mechanism 6 disposed on the rotating platform 1.
[0031] Multiple targets 3 are arranged along the circumference of the rotating platform 1, preferably evenly distributed. The multiple targets 3 can be different targets for testing different needs. Each target rotation mechanism 4 independently drives the corresponding target 3 to rotate around its own axis. The lifting mechanism 5 is disposed on the rotating platform 1 and is used to drive the corresponding target 3 and its target rotation mechanism 4 to move in the vertical direction. The moving mechanism 6 is disposed on the corresponding target rotation mechanism 4 and is used to control the linear movement of the corresponding target 3. The lifting mechanism 5 can be a linear module arranged in the vertical direction in the prior art, and the moving mechanism 6 can be a linear module arranged in the horizontal direction in the prior art.
[0032] This invention integrates multiple targets 3 distributed along the circumference of a rotating platform 1. A rotating mechanism 2 controls the rotation of the platform 1, allowing the targets 3 at different positions to rotate to the orientation corresponding to the rigid endoscope under test, thus completing tests for different needs of the rigid endoscope. Each target 3 is equipped with an independent rotating mechanism 4 to facilitate testing the imaging of the rigid endoscope at different angles and to simulate the imaging effect under rotation, more realistically reflecting the dynamic performance of the rigid endoscope in actual surgery. A lifting mechanism 5 and a moving mechanism 6 realize the vertical lifting and linear displacement of the targets 3 to adapt to various testing needs of different rigid endoscopes at different positions. It can also accurately simulate the relative positional changes of instruments and tissues during surgery, improving the comprehensiveness and accuracy of the test. This invention, through multi-target 3 collaborative testing, significantly improves testing efficiency, avoids repeated adjustments to the testing device, and effectively solves the problems of low efficiency and limited simulation of working conditions in traditional rigid endoscope testing, providing a more scientific and efficient testing method for rigid endoscope performance evaluation.
[0033] In one embodiment, such as Figure 3 As shown, the rotating mechanism 2 includes a first rotary motor 21, a first drive gear 22 connected to the output end of the first rotary motor 21, and a first driven gear 23 meshing with the first drive gear 22. The first driven gear 23 is connected to the rotating platform 1. Specifically, the rotating mechanism 2 is disposed at the bottom of the rotating platform 1. The rotating mechanism 2 also includes a first base 24, on which a first support shaft 25 is disposed. A first bearing 26 is disposed between the rotating platform 1 and the first support shaft 25. The rotating platform 1 and the first driven gear 23 are both connected to the outer periphery of the first bearing 26. Under the action of the first rotary motor 21, the first drive gear 22 rotates, which drives the first driven gear 23 to rotate around the first support shaft 25. The rotation of the first driven gear 23 drives the outer periphery of the first bearing 26 connected to it to rotate, and the rotation of the outer periphery of the first bearing 26 causes the rotating platform 1 connected to it to rotate around the first support shaft 25.
[0034] In this embodiment, the rotating mechanism 2 is set at the bottom of the rotating platform 1, making full use of space and making the overall structure more compact, while facilitating maintenance and repair; the transmission connection between the first driving gear 22 and the first driven gear 23 can effectively reduce the impact of the vibration of the first rotating motor 21 on the rotating platform, ensuring the stability and accuracy of the platform rotation.
[0035] In one embodiment, there are four targets 3, which are evenly distributed along the circumference of the rotating platform 1.
[0036] In one embodiment, a first target 31, a second target 32, a third target 33, and a fourth target 34 are sequentially arranged along the circumference of the rotating platform 1. The first target 31 and the third target 33 are adjusted in the same way, and the corresponding target rotation mechanism 4 is mounted on the rotating platform 1 via a support base 35. The first target 31 and the third target 33 are mounted on the corresponding target rotation mechanism 4. The second target 32 and the fourth target 34 are adjusted in the same way, and the corresponding target rotation mechanism 4 is mounted on the sliding seat of the lifting mechanism 5. The lifting mechanism 5 can be a linear module arranged vertically in the prior art. A moving mechanism 6 is provided on the target rotation mechanism 4. The second target 32 and the fourth target 34 are mounted on the sliding seat of the moving mechanism 6. The moving mechanism 6 can be a linear module arranged horizontally in the prior art.
[0037] like Figure 8 As shown, specifically, the target rotation mechanism 4 includes a support platform 41 and a support platform rotation mechanism for controlling the rotation of the support platform 4. The support platform rotation mechanism includes a second rotary motor 42, a second drive gear 43 connected to the output end of the second rotary motor 42, and a second driven gear 44 meshing with the second drive gear 43. The second driven gear 44 is connected to the support platform 41. More specifically, the support platform rotation mechanism also includes a second base 45, on which a second support shaft 46 is provided. The support platform 41 and the second support shaft 46 are connected by a second bearing 47. The support platform 41 and the second driven gear 44 are both connected to the outer periphery of the second bearing 47. Under the action of the second rotary motor 42, the second drive gear 43 rotates, which drives the second driven gear 44 to rotate around the second support shaft 46. The rotation of the second driven gear 44 drives the outer periphery of the second bearing 47 connected to it to rotate, and the rotation of the outer periphery of the second bearing 47 causes the support platform 41 connected to it to rotate around the second support shaft 46.
[0038] In this embodiment, the first target 31 and the third target 33 can be mounted on the support platform 41. The rotation of the support platform 41 enables the rotation of the first target 31 and the third target 33, thereby adjusting their angles. The target rotation mechanisms 4 corresponding to the second target 32 and the fourth target 34 are mounted on the sliding seat of the lifting mechanism 5. The moving mechanism 6 is mounted on the support platform 41 of the target rotation mechanism 4. The second target 32 and the fourth target 34 are mounted on the sliding seat of the moving mechanism 6, so that the second target 32 and the fourth target 34 can be raised and lowered vertically, rotated along their own axis, and moved horizontally to adjust to different height positions, rotation angles, and horizontal positions.
[0039] In one embodiment, the plurality of targets 3 include one or more of the following: resolution test target, distortion test target, depth of field test target, transmittance and uniformity test target, and color reproduction test target.
[0040] This utility model's multi-target testing platform for rigid microscopes also includes a control system. The control system is electrically connected to the rotating mechanism 2, the target rotation mechanism 4, the lifting mechanism 5, and the moving mechanism 6. The control system coordinates the movement of each mechanism. By using the control system to coordinate the rotation and position adjustment of the rotating platform 1 and the target 3, the testing process is automated, reducing human error and ensuring the consistency and reliability of the test results. The structure is compact and efficient: the integrated design of the rotating platform 1 and the multi-target 3 enables multifunctional testing within a limited space, suitable for the testing needs of rigid microscopes of different specifications, and possesses high versatility and practicality.
[0041] In one embodiment, the rigid mirror multi-target testing platform of this invention further includes a position sensor 7 for real-time feedback and control of the position of the target 3, the position sensor being connected to the control system.
[0042] Those skilled in the art should understand that the specific embodiments described above are merely examples and not limitations. Various modifications, combinations, partial combinations, and substitutions can be made to the embodiments of this utility model according to design requirements and other factors, as long as they are within the scope of the appended claims or their equivalents, and thus fall within the scope of the rights to be protected by this utility model.
