Description

Technical Field

[0001] The present application relates to the technical field of medical device inspection and testing equipment, and in particular to a fundus camera inspection tool with a quick clamping mechanism. Background Art

[0002] Fundus cameras are mainly used to examine the vitreous body, retina, choroid and other parts, thereby assisting in the diagnosis of eye diseases such as high myopia, glaucoma, retinal degeneration, retinal vein occlusion, etc., and are an important tool for patients with eye diseases to undergo examinations.

[0003] During the R&D and testing phases of fundus cameras, a simulated eye is often required to perform various auxiliary tests on the fundus camera. In related technologies, the fundus camera is equipped with a prosthetic eye holder for placing the simulated eye. The simulated eye is mounted on the prosthetic eye holder and then fixed to the fundus camera at the location to be tested.

[0004] In the practical application of fundus cameras, the position of the eyeball on the face varies from patient to patient. The distance between the eyeball and the mandible can fluctuate depending on factors such as gender, age, and facial midriff length. Consequently, the degree of alignment between the eye and the fundus camera varies from patient to patient. Regarding the aforementioned related technologies, prosthetic eye holders typically fix the prosthetic eye in the same position on the fundus camera, resulting in test data that does not accommodate fluctuations. Therefore, a testing fixture capable of adjusting the position of the fundus camera is needed. Utility Model Content

[0005] In order to improve the problem that the inspection tool cannot adjust the position on the fundus camera, the present application provides a fundus camera inspection tool with a quick clamping mechanism.

[0006] The present application provides a fundus camera inspection tool with a quick clamping mechanism, which adopts the following technical solutions:

[0007] A fundus camera inspection tool with a quick clamping mechanism includes a base mounting plate for connecting to other components, a face support plate arranged perpendicular to the base mounting plate, and a prosthetic eye support assembly detachably connected to the face support plate for testing, the face support plate is provided with a mounting port that cooperates with the prosthetic eye support assembly, the prosthetic eye support assembly includes a connecting seat for connecting to the face support plate, an eye simulation seat arranged above the connecting seat, two fundus camera simulation eyes inserted on the eye simulation seat, and a longitudinal connecting beam fixedly connected between the connecting seat and the eye simulation seat, and the connecting seat is provided with a quick clamping mechanism for quick disassembly and assembly with the face support plate.

[0008] By adopting the above-mentioned technical solution, a mounting port that matches the prosthetic eye bracket assembly is provided on the face support bracket plate, and a quick clamping mechanism is provided, so that the prosthetic eye bracket assembly can be quickly and conveniently installed and its position adjusted on the fundus camera. This solves the problem that traditional fixed prosthetic eye brackets cannot adapt to the differences in eye positions of different patients, and improves the accuracy and adaptability of inspection and testing. Since it can simulate the eye positions of different patients, the inspection tooling can generate more volatile and realistic test data, thereby accurately reflecting the performance of the fundus camera under different conditions. This is of great significance for the research and development, testing and quality control of fundus cameras. The setting of the quick clamping mechanism makes the installation and removal of the prosthetic eye bracket assembly on the face support bracket plate simple and quick, improving the efficiency of inspection work.

[0009] Furthermore, the quick clamping mechanism includes two sliding parts symmetrically arranged and slidably installed on the connecting seat, a connecting rod fixedly connected to the connecting seat and located between the two sliding parts, and a spring sleeved on the connecting rod. The connecting seat is provided with a transverse groove along the length direction for installing the connecting rod and the spring. The two ends of the connecting rod are respectively passed through the two sliding parts and are slidably connected to the two sliding parts.

[0010] By employing this technical solution, the slider, coupled with a spring mounted on the connecting rod, achieves a quick clamping function, making it easy for the operator to attach the prosthetic eye support assembly to the face support plate or quickly adjust its position as needed, streamlining the process and improving work efficiency. The spring enables the slider to automatically adapt and apply the appropriate clamping force during the clamping process, securing the prosthetic eye support assembly to the fundus camera. This reduces vibration and errors during testing and improves the accuracy of test data.

[0011] Furthermore, the sliding member includes a card plate that is clamped and slides on the connecting seat, and an operating block that is perpendicularly arranged and fixedly connected to the card plate. The connecting seat is symmetrically provided with two sliding grooves for the two operating blocks to pass through and slide. The connecting seat is integrally connected along the length direction to the limiting convex steps that are limitedly located on both sides of the card plate and for the card plate to slide.

[0012] The connecting seat is provided with a cover plate on one side of the card plate, the cover plate is fixedly connected to the connecting seat, and the cover plate abuts against the side of the two card plates away from the operating block;

[0013] The connecting seat is symmetrically provided with two extension parts on a side away from the cover plate for clamping the face support bracket plate together with the two clamping plates.

[0014] By adopting the above technical solution, the card plate is engaged and slides with the connecting seat, and the setting of the limiting convex step is coordinated to ensure the stability and reliability of the sliding part during the sliding process, prevent the sliding part from shifting or falling off when subjected to force, and ensure the stability of the artificial eye bracket assembly on the fundus camera. The operating block and the card plate are perpendicular to each other and fixedly connected, which makes it convenient for the operator to control the sliding of the sliding part through the operating block. Pinch the two operating blocks so that the two are close to each other and then move away from each other through the spring, thereby realizing the movement of the card plate, thereby forming a groove structure between the two extensions of the face support bracket plate for clamping the face support bracket plate. The setting of the cover plate can have a limiting effect on the sliding part, ensuring that the sliding part can always slide between the two limiting convex steps, thereby improving the sliding stability of the sliding part.

[0015] Furthermore, the connecting seat is integrally connected with a mounting post for mounting the cover plate, the clamping plate is provided with a waist-shaped groove for the mounting post to pass through, and the mounting post extends out of the waist-shaped groove and is threadedly connected to the cover plate.

[0016] By adopting this technical solution, the threaded connection between the mounting post and the cover plate provides a more secure fixation, preventing the cover plate from loosening or falling off during use. This ensures the stability of the entire quick-clamping mechanism within the fundus camera inspection tooling, improving the overall structural strength of the inspection tooling. The waist-shaped groove allows the mounting post to pass through the clamping plate while also providing sliding travel for the clamping plate, ensuring the sliding adjustment of the slider.

[0017] Furthermore, the two extension parts are symmetrically arranged on both sides of the connecting seat, and the two extension parts are respectively penetrated by at least one elastic connector for pressing against the face support bracket plate.

[0018] By adopting the above technical solution, an elastic connector is provided on the extension part, which can clamp the face support bracket more firmly, help reduce shaking and errors during the test process, and improve the accuracy of the test data.

[0019] Furthermore, the eye simulation seat has two mounting tubes for inserting the fundus camera simulated eye and a crossbeam integrally connected between the two mounting tubes and perpendicular to the longitudinal connecting beam body;

[0020] One end of the mounting tube is provided with a limiting ring plate on the inner peripheral wall for contacting with the fundus camera simulated eye, and one end of the fundus camera simulated eye away from the limiting ring plate protrudes from the mounting tube.

[0021] By adopting the above technical solution, the mounting tube enables the fundus camera simulated eye to be accurately inserted and fixed on the eye simulation seat, thereby simulating the position of the real eyeball. The precise simulation effect helps to improve the test accuracy of the fundus camera inspection tooling, so that it can more realistically reflect the performance of the fundus camera in actual application. The setting of the limit ring plate ensures the stability of the fundus camera simulated eye in the mounting tube. When the fundus camera simulated eye is inserted into the mounting tube, the limit ring plate will abut it to prevent it from shaking or falling off during the test, which helps to reduce test errors and improve the reliability of test data. The fundus camera simulated eye is set up outside the mounting tube, making the simulated eye easy to replace and maintain.

[0022] Furthermore, the fundus camera simulates an eye with an annular groove on its outer peripheral wall near one end of the limiting ring plate, the mounting tube is provided with a snap-fitting protrusion for snapping into the annular groove, and the mounting tube is provided with a deformation groove on its side wall for matching with the snap-fitting protrusion.

[0023] By adopting this technical solution, a circular groove is defined on the outer wall of the fundus camera's simulated eye, and a latching protrusion is provided within the mounting barrel. When the fundus camera's simulated eye is inserted into the mounting barrel, the latching protrusion snaps into the groove, achieving a more secure fixation. Compared to simple insertion or threaded connections, it offers greater stability and resistance to disengagement. The deformation groove allows the mounting barrel to deform slightly when the latching protrusion snaps into the groove, simplifying assembly and disassembly operations and preventing damage to the simulated eye or mounting barrel due to excessive force.

[0024] Furthermore, a plurality of ridges are arranged at intervals along the circumference of the inner wall of the mounting tube for contacting the outer circumference of the fundus camera simulated eye, and each of the ridges is arranged along the length direction of the mounting tube.

[0025] By adopting this technical solution, the raised ridges increase the contact area between the inner wall of the mounting tube and the outer wall of the fundus camera simulated eye, improving friction between the two. This makes the fundus camera simulated eye more stable within the mounting tube, less likely to shake or fall out, and helps ensure stability and accuracy during testing. The multiple raised ridges are spaced circumferentially, so that when the fundus camera simulated eye is subjected to external forces, the force is evenly distributed across the ridges, preventing damage caused by excessive force at a single point. This even force distribution helps protect the fundus camera simulated eye and extend its service life.

[0026] Furthermore, the longitudinal connecting beam includes a longitudinal plate body integrally connected to the lower side of the cross beam and the upper side of the connecting seat, and reinforcing plates vertically arranged on both sides of the longitudinal plate body.

[0027] By adopting this technical solution, the reinforcement plate enhances the structural strength of the longitudinal connecting beam, forming a more stable support structure with the longitudinal plate, thereby withstanding greater loads and impact forces, helping to ensure the stability and safety of the inspection fixture during testing. The coordinated arrangement of the longitudinal plate and reinforcement plate increases the overall rigidity of the inspection fixture, helping to reduce testing errors caused by equipment deformation and improving the accuracy of test data.

[0028] Furthermore, the base mounting plate is fixedly connected to a lower side with an adjustable wire buckle for fixing other components.

[0029] By adopting the above technical solution, the setting of the adjustable wire tie allows the operator to adjust the fixing position and tightening strength according to actual needs. The flexible setting makes it easier for the inspection tooling to adapt to the installation requirements of different components. The adjustable wire tie simplifies the installation process. There is no need to use complex tools or make tedious adjustments. Just connect the components to be fixed with the wire tie and make fine adjustments as needed. The quick and easy installation method improves work efficiency.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. The face support bracket is equipped with a mounting port that matches the prosthetic eye bracket assembly and a quick clamping mechanism to enable quick and convenient installation and position adjustment of the prosthetic eye bracket assembly on the fundus camera. This solves the problem that traditional fixed prosthetic eye brackets cannot adapt to the differences in eye position among different patients, improves the accuracy and adaptability of the test, and by simulating the eye positions of different patients, generates more volatile and realistic test data, accurately reflecting the performance of the fundus camera under different conditions.

[0032] 2. The quick-clip mechanism makes installation and removal of the prosthetic eye support assembly simple and quick, improving inspection efficiency. The sliding part achieves quick-clip function through a spring mounted on the connecting rod, simplifying the operation steps and making it easier for operators to install and adjust the position of the prosthetic eye support assembly.

[0033] 3. Attachment protrusions and deformation grooves are installed within the mounting tube of the fundus camera's simulated eye, and multiple ridges are spaced circumferentially around the inner wall of the tube to enhance the stability of the fundus camera's simulated eye within the tube. A reinforcement plate enhances the structural strength of the longitudinal connecting beam and, together with the longitudinal plate, forms a more stable support structure capable of withstanding greater loads and impact forces, ensuring the stability and safety of the inspection fixture during testing.

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-6 And embodiments, the present application is further described in detail.

[0042] The present application discloses a fundus camera inspection tool with a quick clamping mechanism. Figure 1 and Figure 2The fundus camera inspection tool with a quick-release mechanism includes a base mounting plate 1, a face support plate 2, and a prosthetic eye support assembly 3. The base mounting plate 1 can be connected to the other components of the fundus camera. The face support plate 2 is arranged perpendicular to the base mounting plate 1. The prosthetic eye support assembly 3 can be detachably connected to the face support plate 2 for testing. An adjustable cable buckle 11 is fixedly connected to the bottom side of the base mounting plate 1, which can be used to secure the other components of the fundus camera.

[0043] An installation opening 21 is provided on the face support bracket plate 2. The opening size of the installation opening 21 in this embodiment is larger than the size of the artificial eye bracket assembly 3, so that the artificial eye bracket assembly 3 cooperates with the installation opening 21, thereby being able to adjust the installation position of the artificial eye bracket assembly 3 on the face support bracket plate 2.

[0044] Reference Figure 3 and Figure 4 The artificial eye support assembly 3 includes a connecting base 31, an eye simulation base 32, a fundus camera simulated eye 33, and a longitudinal connecting beam 34. The connecting base 31 is used to connect to the face support support plate 2. The eye simulation base 32 is located above the connecting base 31 and is arranged parallel to the connecting base 31. There are two fundus camera simulated eyes 33 and they are symmetrically inserted on the eye simulation base 32. The longitudinal connecting beam 34 is arranged vertically and integrally connected between the connecting base 31 and the eye simulation base 32.

[0045] The connecting base 31 is equipped with a quick-release mechanism 35 for rapid assembly and disassembly with the face support bracket 2. The quick-release mechanism 35 comprises two symmetrically arranged sliders 351 slidably mounted on the connecting base 31, a connecting rod 352 fixedly connected to the connecting base 31 and positioned between the two sliders 351, and a spring 353 mounted on the connecting rod 352. The spring 353 is mounted in the middle of the connection. The ends of the connecting rod 352 pass through the two sliders and slide in connection with each other. A transverse groove 311 is defined in the middle of the connecting base 31 along its length. The middle of the connecting rod 352 and the spring 353 engage within the transverse groove 311.

[0046] Combine Figure 5 The sliding member 351 includes a clamping plate 3511 and an operating block 3512, which are arranged perpendicular to each other and integrally connected. The connecting base 31 has two symmetrical sliding slots 312 for the operating block 3512 to slide through. A stopper 313 is integrally connected to one side of the connecting base 31 along its length, which is used to limit the position of the clamping plate 3511 on both sides. The clamping plate 3511 is engaged and slides on the connecting base 31 via the stopper 313.

[0047] Reference Figure 4 and Figure 5The connector 31 has a cover plate 314 on one side near the clamping plate 3511 to prevent the sliding member 351 from falling out. A mounting post 315 for mounting the cover plate 314 is vertically disposed adjacent to the sliding slot 312 on the connector 31. The clamping plate 3511 defines a waist-shaped groove 35111 for the mounting post 315 to pass through. One end of the mounting post 315 is integrally connected to the connector 31. The end of the mounting post 315, away from the connector 31, extends out of the waist-shaped groove 35111 and is threadedly connected to the cover plate 314.

[0048] The connecting base 31 is provided with an extension portion 316 on the side away from the cover plate 314 for cooperating with the face support bracket plate 2. There are two extension portions 316, which are symmetrically arranged and integrally connected to the two sides of the connecting base 31. The two extension portions 316 and the two clamping plates 3511 together form two groove structures that can be used to clamp the face support bracket plate 2. Figure 3 Two elastic connectors 317 are respectively provided on the two extension parts 316, which are spaced apart from each other. When the quick clamping mechanism 35 clamps the connecting seat 31 on the face support bracket plate, the elastic connector 317 is pressed against the face support bracket plate, thereby enhancing the stability of the artificial eye bracket assembly 3 clamped on the face support bracket plate.

[0049] Reference Figure 5 and Figure 6 The eye simulation seat 32 includes two symmetrically arranged mounting tubes 321 and a crossbeam 322 integrally connected between the two mounting tubes 321. The longitudinal connecting beam 34 is fixedly connected to the lower side of the crossbeam 322 and integrally connected to the crossbeam 322. Figure 3 One end of the mounting tube 321 is integrally connected to the inner circumferential wall with a limit ring plate 3211. The inner wall of the mounting tube 321 is circumferentially spaced with multiple ridges 3212, each extending along the length of the mounting tube 321. When the fundus camera simulated eye 33 is inserted into the mounting tube 321, the limit ring plate 3211 abuts against the end of the fundus camera simulated eye 33, and each ridge 3212 abuts against the outer circumferential wall of the fundus camera simulated eye 33, causing the end of the fundus camera simulated eye 33 away from the limit ring plate 3211 to protrude from the mounting tube 321.

[0050] The fundus camera simulated eye 33 has an annular groove 331 defined on its outer peripheral wall near one end of the retaining ring plate 3211. A snap-in protrusion 3213 is provided within the mounting tube 321, designed to engage with the annular groove 331. The mounting tube 321 also has a deformable groove 3214 defined on its side wall, which mates with the snap-in protrusion 3213. When the fundus camera simulated eye 33 is inserted into the mounting tube 321, the snap-in protrusion 3213 engages with the annular groove 331. The deformable groove 3214 allows the mounting tube 321 to deform slightly when the snap-in protrusion 3213 engages with the annular groove 331, thereby preventing damage to the fundus camera simulated eye 33 or the mounting tube 321 due to excessive force.

[0051] The longitudinal connecting beam 34 includes a longitudinal plate 341 integrally connected to the underside of the crossbeam 322 and the upper side of the connecting seat 31, and a reinforcing plate 342 disposed perpendicularly and integrally connected to both sides of the longitudinal plate 341. The reinforcing plates 342 and the longitudinal plates 341 together form a more stable support structure, thereby enhancing the structural strength of the longitudinal connecting beam 34 and allowing it to withstand greater loads.

[0052] The implementation principle of the fundus camera inspection tool with a quick clamping mechanism in the embodiment of the present application is as follows: when the inspection tool is in use, the operator first inserts the fundus camera simulated eye 33 into the mounting tube 321 of the eye simulation seat 32, and achieves a stable installation through the cooperation of the clamping protrusion 3213 and the annular groove 331. By operating the operating block 3512 of the quick clamping mechanism 35, the sliding member 351 slides on the connecting seat 31, forming a groove structure to clamp the face support bracket plate 2, thereby achieving rapid installation of the artificial eye bracket assembly 3 on the face support bracket plate 2. The base mounting plate 1 is firmly connected to the other components of the fundus camera using the adjustable wire buckle 11 and other fixing methods to complete the assembly of the entire inspection tool. During the test process, the fundus camera simulated eye 33 simulates the position of the real eyeball, and the fundus camera is subjected to performance testing through the inspection tool to ensure that its performance under different conditions meets the requirements.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
