Description

Technical Field

[0001] The present invention relates to the technical field of medical instrument testing, and in particular to a bionic eyeball structure based on a real eyeball environment and a testing system thereof. Background Art

[0002] The eyeball is the most important organ in the human visual system, and its physiological structure is complex. At present, research teams have created bionic components such as artificial corneas, artificial lenses, and artificial retinas, trying to treat diseases of various components of the eye structure caused by factors such as genetics, improper postnatal protection, bacterial and viral infections, trauma, and even metabolic diseases. However, these bionic components have not yet been directly applied to real human eyes. Currently, they are only tested in artificial eyes or animal eyes to test their performance. However, artificial eyes or animal experiments cannot obtain real-time feedback information, which leads to the fact that the effect of such components based on bionic technology may not achieve the expected effect after being applied to clinical trials. The problems existing in the test platform for the research of these bionic components are summarized as follows:

[0003] The most important medical concern about eye components is the optical effect, but these research and testing platforms (artificial eyes or animals) cannot provide effective feedback on the optical effects of eye components, making it difficult to obtain the actual effects of using these components before human clinical trials.

[0004] These eye-mimicking components will eventually need to work in a real human eye environment, but the test platforms for these components all use a metal shell to simulate the outer wall of the eye, with an air environment inside, which is too different from the real eye environment.

[0005] The bionic components of the various structural components of the eyeball need to be tested on animals, which is time-consuming and economically expensive and will extend the product testing cycle. And because no feedback can be obtained, if the results are not ideal, it is necessary to repeat relatively long animal experiments, which naturally costs more.

[0006] Regarding the construction technology of the bionic eye, Fan Zhiyong's team designed a method of closely arranging photosensitive nanosensors on a hemisphere to mimic the retina of the human eye. These sensors are then connected to a bundle of wires made of liquid metal, which act as optic nerves and transmit optical signals from the artificial retina. The bionic retina made by this method can achieve a sensitivity comparable to that of human retinal photoreceptor cells, but the bionic component uses a metal shell to replace the outer shell of the eyeball as a support, and cannot simulate the working environment of the real eyeball very well. Actual testing on living organisms is also the biggest challenge that this technology currently faces. As mentioned above, this method lacks a platform that can simulate the real human eye environment for testing. Whether humans are compatible with bionic eyes and the unknown effect of applying them to real eyeballs are all obstacles to whether this technology can be widely promoted and used. Summary of the invention

[0035] The bionic eyeball structure based on the real eyeball environment comprises a bionic eye socket 1, a liquid conduit 2, a hydraulic screw drive motor 3, a tear control valve 4, a bionic eyelid 5, a rotary motor 6, an artificial eyeball 7, an artificial cornea 8, an artificial ciliary body 9, an artificial lens 10, an artificial retina 11 and a drive motor 12; a spherical shell with an opening made of metal is used as the bionic eye socket 1, and springs 13 and damping elements 14 are evenly distributed on the inner surface of the bionic eye socket 1 to connect the artificial eyeball 7, so as to simulate the eye movement effect of a real human eye, so that the artificial eyeball can realize the mechanical movement (rotation, translation, etc.) that a real eyeball would produce, and a groove 15 is built in the opening of the bionic eye socket 1, and the groove 15 is arranged with a spring 13 and a damping element 14. A track with a pulley 16 is provided, and a shell made of high-transparency PVC (actually a 1 / 8 spherical shell) that can slide along the track is placed therein as a bionic eyelid 5, and a buffer pad 17 is provided at the end of the track. The bionic eyelid 5 is driven by a rotary motor 6 to cycle along the axis of the spherical shell. The upper opening of the bionic eye socket 1 is used for the passage of a liquid conduit 2, and the liquid conduit 2 passes through the bionic eye socket 1 and is respectively connected to the bionic eyelid 5 and the artificial eyeball 7, and is externally connected to a hydraulic screw transmission motor 3, and the hydraulic screw transmission motor 3 is used to control the hydraulic pressure inside the artificial eyeball 7 to simulate the change of intraocular pressure in the real eyeball, and a liquid conduit 2 leading to the bionic eyelid 5 is provided. The tear control valve 4 is used to control the flow to the bionic eyelid 5 to achieve the purpose of controlling the wetness of the corneal surface. Specifically, the liquid passing through the tear control valve 4 flows to the corneal surface of the artificial eyeball 7 at an appropriate rate to maintain the wetness of the surface of the real human eye. The artificial cornea 8 and the artificial eyeball 7 are arranged in a chimeric manner. According to the position of the ciliary body in the real eyeball, the artificial ciliary body 9 (a convex block installed inside the artificial eyeball 7) is installed in the artificial eyeball 7. The artificial ciliary body 9 is provided with an interface to connect with the loop of the artificial lens 10. A channel 19 with a pulley 18 is provided in the artificial ciliary body 9. A traction line 20 is provided in the channel 19 to bypass the pulley 18 to connect the artificial lens 10 with the external The driving motor 12 can pull the artificial lens 10 by the driving motor 12 to realize artificially controlled lens deformation and achieve the zoom function, so that the image received by the imitation retina 11 can achieve the ideal effect. The imitation retina 11 is a planar optical receiver integrated with a photosensitive element. The imitation retina 11 can receive light refracted by the artificial cornea 8 and the artificial lens 10, and further convert the received light signal into an electrical signal, and transmit the electrical signal to the data acquisition and processing module through a data line for processing, so as to obtain real-time feedback evaluation of image morphology, imaging position, and image quality. The imitation retina 11 can use waterproof materials to prevent the liquid inside the artificial eyeball from interfering with the photosensitive element itself.

[0036] Preferably, the hydraulic screw drive motor 3 is composed of a hydraulic sensor, a chamber containing liquid and a stepper motor, and is connected to a data acquisition and processing module. The hydraulic sensor transmits the liquid pressure result in the chamber to the data acquisition and processing module, and then through manual control, drives the stepper motor to pressurize the chamber so that the hydraulic pressure in the chamber becomes the required hydraulic level.

[0037] Preferably, the artificial eyeball 7 is a hollow spherical shell made of a hydrogel-metal shell, the front hemisphere is made of silicone, which is convenient for the built-in imitation ciliary body, the front end is embedded with an artificial cornea made of hydrogel to prevent leakage when the artificial eyeball is filled with liquid, and the rear hemisphere is made of metal, which mainly plays a fixing role, and is connected to the bionic eye socket 1 with a spring 13 and a damping element 14 as a medium, so as to simulate the eye movement effect of a real human eye.

A photosensitive element is placed at the rear end of the artificial eyeball 7, and is connected to a data acquisition and processing module, and the image formed by the light refracted by the artificial cornea and artificial lens is transmitted to the data acquisition and processing module, providing real-time feedback image data in product testing. The artificial cornea product and artificial lens product that need to be tested can be replaced and installed on the artificial eyeball 7, and the product performance can be tested under the premise of ensuring that the basic structural function is not affected: 1. During the mechanical periodic movement of the bionic eyelid 5, the contact between the artificial cornea 8 and the bionic eyelid 5 will produce mechanical friction, thereby realizing the fatigue durability test of the artificial cornea 8; 2. When the hydraulic screw transmission motor 3 changes the internal pressure of the artificial eyeball 7 through the liquid conduit 2, the pressure resistance test of the artificial lens 10 can be carried out.

[0038] The artificial cornea 8 is a relatively important component in the present invention. The present invention has an artificial cornea made of hydrogel with various corneal geometric and mechanical characteristics such as corneal thickness, corneal curvature, corneal modulus, etc. as a component. It is not only an experimental object for optical testing and corneal fatigue durability testing, but also an important component for intraocular pressure measurement and calibration. It is necessary to use a mechanical testing machine to perform intraocular pressure testing and establish an experimental database to complete the measurement and calibration of the intraocular pressure value affected by various factors (different geometric and mechanical factors of the cornea, different intraocular pressure values), so as to solve the difficulty of large numerical errors in the current single measurement and continuous monitoring of intraocular pressure. Similarly, the artificial cornea component can also replace other artificial cornea products that need to be tested. In addition to completing the performance required for the test of this product, it can also be compared with the performance of the gel cornea, which can improve the corresponding research in the field of gel cornea.
