Description

Technical Field

[0001] The invention belongs to the technical field of ophthalmic models, and in particular relates to a program-controlled bionic simulation device for the movement of both eyeballs and extraocular muscles and its application. Background Art

[0002] In ophthalmology teaching, medical research or popular science demonstrations and other related fields, it is very important to have a deep understanding of the movement mechanism of the human eyeballs and extraocular muscles. This is because the movement of the eyeballs and extraocular muscles plays an extremely critical role in the human visual system. The eyeballs can quickly focus on objects of interest through different types of movements such as saccades, tracking and micro-saccades, maintain visual stability, and help us obtain rich information about the surrounding environment. Figure 1 The six muscles shown are composed of four rectus muscles: superior rectus A, inferior rectus B, lateral rectus C, medial rectus D and two oblique muscles: superior oblique E, inferior oblique F. These six muscles are staggered around the eyeball and their spatial positions around the eyeball are extremely complex. Under the precise control of the nervous system, these muscles change the position of the eyeball through contraction and relaxation to achieve precise eye movement in different directions. Once the extraocular muscle function is impaired, it may lead to abnormal eye movement, such as strabismus, diplopia and other problems. In short, the complex and precise process of eyeball and extraocular muscle movement is crucial to our visual function.

[0003] However, taking ophthalmology teaching as an example, the current traditional ophthalmology teaching method mainly adopts the diagram method and the model method, which has the following defects in practice: first, the diagram method relies on the flat images in the book and the teacher's oral explanation to impart knowledge, which is relatively abstract, making it difficult for students to intuitively feel the actual process of eye movement and the specific role of the extraocular muscles, which leads to great difficulties in their understanding of the complex eye physiological structure and movement principle; second, the existing teaching model can only show the static structure of the eyeball, and cannot dynamically simulate the control of the extraocular muscles on the movement of the eyeballs, that is, lack of accurate description of the relationship between the eyeball and the extraocular muscles in the moving state, which is difficult to meet the high requirements of modern ophthalmology teaching for intuitiveness and interactivity. In addition, the existing public model, such as the model shown in the Chinese public patent number CN214312337U, named a multifunctional human eyeball model for teaching demonstration, although it can simulate the eyeball such as the process of the muscles in the eyeball adjusting the lens, it cannot show the relationship between the eyeball movement and the movement of the extraocular muscles.

[0004] In view of the above situation, this invention is proposed to provide a more effective auxiliary tool for related fields such as ophthalmology teaching, medical research or popular science display. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a programmable bionic simulation equipment for the movement of both eyeballs and extraocular muscles. The equipment is mainly used to solve the problem that the movement process of the eyeballs and extraocular muscles cannot be clearly and intuitively displayed in current ophthalmology teaching, medical research or popular science demonstrations, and it is difficult to accurately present the complex antagonistic or synergistic relationship between the extraocular muscles, which brings great inconvenience to teaching and demonstrations. The present invention enables students to have a deeper understanding of the movement principles and interaction relationships of the human eyeballs and extraocular muscles through precise simulation and intuitive demonstration.

[0006] The purpose of the present invention is to be solved by the following technical solutions:

[0007] On the one hand, the present invention provides a program-controlled bionic simulation equipment for double eyeball and extraocular muscle movement, comprising a base, two simulated eye socket frames are symmetrically arranged on the surface of the base, each of the simulated eye socket frames is provided with a spherical shell-shaped simulated eyeball, and a support bracket is fixedly arranged in each of the simulated eye socket frames on the surface of the base, and a driving component is arranged at one end of the support bracket extending into the simulated eyeball, and the driving component is fixedly connected to the simulated eyeball and is used to drive the simulated eyeball to perform rotational movement on a horizontal plane and / or a vertical plane;

[0008] Wherein, the outside of each simulated eyeball is provided with a ligament group simulating the extraocular muscles of the human body, and the ligament group is composed of a first ligament simulating the superior rectus muscle, a second ligament simulating the inferior rectus muscle, a third ligament simulating the lateral rectus muscle, a fourth ligament simulating the medial rectus muscle, a fifth ligament simulating the superior oblique muscle, and a sixth ligament simulating the inferior oblique muscle. The first ligament is connected to the upper top of the simulated eyeball, the second ligament is connected to the lower bottom of the simulated eyeball, the third ligament is connected to the outer center of the simulated eyeball, and the fourth ligament is connected to the inner center of the simulated eyeball.

[0009] The device also includes a remote controller, which can wirelessly drive the simulated eyeball and the ligaments arranged on the simulated eyeball to perform corresponding movements.

[0010] Furthermore, the driving assembly is arranged inside the simulated eyeball, including a first servo fixedly connected to the supporting bracket, the output shaft of the first servo fixedly connected to a mounting frame, the mounting frame fixedly mounted with a second servo, and the output shaft of the second servo is perpendicular to the output shaft of the first servo, the output shaft of the second servo is fixedly provided with a connecting frame, and the connecting frame is fixedly connected to the inner wall of the simulated eyeball through multiple sets of legs.

[0011] Furthermore, the connecting frame is a gate-shaped connecting frame, and the gate-shaped connecting frame is connected to the simulated eyeball through multiple groups of supporting legs, and the multiple groups of supporting legs are distributed around the gate-shaped connecting frame.

[0012] Furthermore, a laser emitter simulating the visual axis is installed at the front center of the shell of each simulated eyeball, and a visual axis target is arranged on the base, directly in front of the simulated eyeball, and the visual axis target is used to project and display the laser visual axis and movement trajectory emitted by the laser emitter.

[0013] Furthermore, the base is a shell structure, a control circuit board is arranged inside the base, an input end of the control circuit board is connected to an external power supply through a power adapter, and an output end of the control circuit board is electrically connected to the first steering gear, the second steering gear and the laser transmitter respectively;

[0014] Alternatively, the laser emitter is directly connected to an external power source, and a switch for independently controlling the laser emitter is provided at the rear of the base.

[0015] Furthermore, the remote controller is connected to a single chip microcomputer provided on a control circuit board by means of communication;

[0017] The remote control can perform both automatic control and manual control. When the remote control issues an automatic control command, the signal transmitting module sends a command signal. After receiving the command signal, the signal receiving module on the control circuit board transmits it to the single-chip microcomputer for processing. The single-chip microcomputer outputs a corresponding control signal to control the first servo and / or the second servo according to the received command signal through a pre-written control program, so that the simulated eyeball automatically performs the corresponding action; or by moving the left remote control rod and / or the right remote control rod of the remote control, the simulated eyeball is controlled to move in the corresponding direction, and after the movement is completed, the left remote control rod, the right remote control rod and the simulated eyeball return to the starting position.

The six ligaments equipped with plumb bobs are correspondingly arranged on the rollers of the first support shell or the second support shell.

[0021] On the other hand, the present invention provides a bionic simulation device based on the above-mentioned programmable eyeball and extraocular muscle movement for use in the fields of ophthalmology teaching, medical research or popular science display.

[0022] Specifically, in the field of ophthalmology teaching, it can be used as a teaching aid. It can show the movement process of the eyeballs and extraocular muscles in an intuitive and dynamic way, allowing students to break away from the limitations of abstract flat images and text descriptions in traditional teaching. By accurately simulating various normal and abnormal eye movement states, it helps students deeply understand the physiological structure and movement principles of the eyes, and enhances their understanding and diagnosis of ophthalmic diseases. For example, it can simulate binocular movements under different diseases such as common esotropia, common exotropia, paralytic exotropia, and paralytic esotropia, so that students can more intuitively feel the changes in eye movements under disease conditions.

[0023] In the field of medical research, the bionic simulation equipment provides researchers with a highly repeatable, precisely controllable experimental platform. Researchers can use it to conduct in-depth studies on the laws of eye movement, the synergy of extraocular muscles, and the pathogenesis of related diseases. By adjusting and observing the parameters of the simulation equipment, the effects of new treatments and rehabilitation techniques on eye movement can be tested, providing an important reference for clinical treatment.

[0024] In the field of popular science display, this equipment has great appeal and educational value. When displayed in science and technology halls, museums and other places, it can popularize ophthalmic knowledge to the public through vivid and intuitive simulation demonstrations. The public can understand the structure and function of the eye by watching the operation of the simulation equipment, and increase the attention paid to eye health. At the same time, its fun and interactivity can also stimulate the public's curiosity and desire to explore science, and promote the dissemination and popularization of scientific knowledge.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] The programmable bionic simulation equipment for eyeball and extraocular muscle movement provided by the present invention has the following advantages:

[0027] First, it provides auxiliary functions for ophthalmology teaching, medical research or popular science exhibitions. Compared with the traditional diagram method, this model can intuitively display the movement and change process of the eyeball and extraocular muscles, so that students are no longer limited to abstract flat images and verbal explanations, so as to deeply understand the actual situation of eye movement and the specific role of extraocular muscles, which greatly improves the teaching effect. Secondly, accurately presenting the complex antagonistic or synergistic relationship between the extraocular muscles (six ligaments) will help students better understand the abnormal eye movement problems that may be caused by extraocular muscle dysfunction, laying a solid foundation for future clinical practice.

[0028] Second, from the perspective of function and operation, the electronic control design makes the operation extremely convenient. By connecting the remote control to the control circuit board, remote operation can be achieved to meet the use requirements of different scenarios. The cooperation of the two servos in the drive assembly can accurately simulate the rotational movement of the eyeball in the horizontal and / or vertical planes, presenting various real eye movement states. In addition, various types of strabismus can be simulated through program control to deepen students' understanding of the disease. At the same time, the setting of the laser transmitter and the visual axis target clearly displays the laser visual axis and movement trajectory, enhancing the intuitiveness of teaching. The simulated orbital frame is made of transparent material, which has a certain degree of transparency to facilitate observation of the internal structure and is durable. The ligament can be selected in two types: elastic or fixed, and is equipped with corresponding auxiliary devices to provide a variety of demonstration methods for teaching to meet the needs of different teaching content.

[0029] In summary, the electric control model of the present invention can dynamically simulate the movement of the eyeballs and extraocular muscles, accurately describe the relationship between the eyeballs and extraocular muscles in motion, and meet the high requirements for intuitiveness and interactivity. Compared with the existing public models, the structure is relatively simple, and can intuitively reflect the relationship between the eyeballs and extraocular muscle movements, avoiding the difficulty of operation and understanding caused by the complex structure, and bringing great convenience to ophthalmology teaching, medical research or popular science display.

[0053] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices consistent with some aspects of the present invention as detailed in the appended claims.

[0054] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0055] Example 1

[0056] See also Figures 2 to 10 , a program-controlled bionic simulation equipment for double eyeball and extraocular muscle movement provided by an embodiment of the present invention comprises a base 1 in a shell structure, on the surface of which two simulated eye socket frames 2 are symmetrically arranged at a vertical interface (or two simulated eye socket frames 2 are arranged as one body and separated by a baffle), each simulated eye socket frame 2 is provided with a spherical shell-shaped (with an opening at the rear) simulated eyeball 3, that is, including a simulated left eyeball 31 and a simulated right eyeball 32, and in each simulated eye socket frame 2, a support bracket 4 is fixedly arranged on the surface of the base 1, and one end of the support bracket 4 extending from the opening into the interior of the shell of the simulated eyeball 3 is provided with a driving component 5, and the output end of the driving component 5 is fixedly connected to the corresponding simulated eyeball 3, and is used to drive the simulated eyeball 3 to rotate on the horizontal plane and / or vertical plane. Preferably, when controlling the movement of the simulated eyeball 3, the driving component 5 can realize single control or linkage control of two simulated eyeballs 3. At the same time, in the embodiment of the present invention, a ligament group 6 simulating human extraocular muscles is arranged at a specific external position of each simulated eyeball 3. It can be seen that the electric control model provided by the present invention can not only control the movement process of the simulated eyeball 3 and the ligament group 6 set on the simulated eyeball 3 individually or simultaneously through the driving component 5, but also can show the antagonistic or synergistic relationship between the ligament groups 6.

[0057] It should be noted that in the embodiment of the present invention, the simulated orbital frame 2 is made of a transparent material, such as glass or acrylic plate, so that the user can clearly observe the movement of the eyeballs and extraocular muscles inside the electric-controlled model, providing a more intuitive observation angle for ophthalmic teaching and research. In addition, the simulated orbital frame 2, simulated eyeball 3, support bracket 4, drive assembly 5 and ligament group 6 arranged on the surface of the base 1 are all arranged in a mirror image (symmetrical) with the vertical interface of the surface of the base 1, so as to accurately simulate the structure of the human eye. Such a design ensures that the model is closer to the real human eye state in appearance and function, providing a more accurate and intuitive tool for ophthalmic teaching and research.

[0058] Specifically, Figure 3 , 8 As shown in Figures 9, in the embodiment of the present invention, the ligament group 6 is composed of a first ligament 61 simulating the superior rectus muscle, a second ligament 62 simulating the inferior rectus muscle, a third ligament 63 simulating the lateral rectus muscle, a fourth ligament 64 simulating the medial rectus muscle, a fifth ligament 65 simulating the superior oblique muscle, and a sixth ligament 66 simulating the inferior oblique muscle. Among them, one end of the first ligament 61 is connected to the upper top of the simulated eyeball 3, one end of the second ligament 62 is connected to the lower bottom of the simulated eyeball 3, one end of the third ligament 63 is connected to the outer center of the simulated eyeball 3, one end of the fourth ligament 64 is connected to the inner center of the simulated eyeball 3, one end of the fifth ligament 65 is connected to the outer upper part of the simulated eyeball 3, and one end of the sixth ligament 66 is connected to the outer lower part of the simulated eyeball 3, that is, the connection points of the fifth ligament 65 and the sixth ligament 66 with the simulated eyeball 3 are located above and below the connection points of the fourth ligament 64 with the simulated eyeball 3; the other ends of the first ligament 61, the second ligament 62, the third ligament 63, the fourth ligament 64 and the fifth ligament 65 respectively pass through the through holes pre-opened at the rear of the simulated orbital frame 2 and are in the first support shell 7 set near the inner side of the simulated orbital frame 2, and the other end of the sixth ligament 66 is set in the second support shell 8 between the two simulated eyeballs 3. It should be noted that a U-shaped slide 81 is provided on the second supporting shell 8 , and one end of the fifth ligament 65 away from the upper outer part of the simulated eyeball 3 passes through the U-shaped slide 81 and is then provided in the first supporting shell 7 .

[0059] In the embodiment of the present invention, the six ligaments in the ligament group 6 are all made of non-elastic materials, for example, a fixed harness is selected (which can be regarded as inelastic). At this time, the ends of the six ligaments away from the simulated eyeball 3 are all equipped with a plumb bob of a certain weight. The first support shell 7 and the second support shell 8 are both fixedly and horizontally provided with a crossbar connector 9, and a roller 91 (such as Figure 5 , 6As shown in the figure, the design of the roller 91 enables the ligaments to slide more smoothly during the movement, reducing friction resistance. The first ligament 61, the second ligament 62, the third ligament 63, the fourth ligament 64 and the fifth ligament 65 are provided with plumb bobs and arranged on the roller 91 in the first support shell 7, and the sixth ligament 66 is provided with plumb bobs and arranged on the roller 91 in the second support shell 8. When simulating eyeball movement, these ligaments slide on the roller 91 to simulate the contraction and extension of the extraocular muscles.

[0060] like Figure 3 As shown, in the embodiment of the present invention, the driving assembly 5 is completely arranged inside the simulated eyeball 3, and the driving assembly 5 includes a first steering gear 51 fixedly connected to the support bracket 4, the output shaft of the first steering gear 51 is arranged vertically, and a mounting frame 52 is fixedly connected to the output shaft of the first steering gear 51, and the mounting frame 52 is used as a bearing component, and a second steering gear 53 is fixedly mounted thereon, and the output shaft of the second steering gear 53 is arranged horizontally, and cooperates with the output shaft of the first steering gear 51 to achieve precise control of the movement of the simulated eyeball 3, and a connecting frame 54 is fixedly arranged on the output shaft of the second steering gear 53, and the connecting frame 54 is fixedly connected to the inner wall of the simulated eyeball 3 through a plurality of groups of legs 55. In this way, through the clever stacking arrangement of the two steering gears in different directions, the first steering gear 51 can drive the second steering gear 53 and the simulated eyeball 3 to rotate along the horizontal plane; at the same time, the second steering gear 53 can drive the simulated eyeball 3 to rotate along the vertical plane. That is to say, through the cooperation of the two servos, the simulated eyeball 3 can be accurately rotated in the horizontal plane and / or vertical plane. It should be noted that as long as the output shaft of the second servo 53 is perpendicular to the output shaft of the first servo 51, the present invention does not specifically limit the inclination angle of the two servos.

[0061] Among them, the connecting frame 54 used in the embodiment of the present invention is a gate-shaped connecting frame, which is connected to the simulated eyeball 3 through multiple groups of legs 55. For example, three groups are set in this embodiment, and each group of legs 55 has two legs, which are arranged side by side. These three groups of legs 55 are respectively arranged on both sides and the top of the gate-shaped connecting frame, and are correspondingly fixedly connected to the two sides and the top of the inside of the simulated eyeball 3, so that the connection is more stable. Under the action of the driving component 5, the gate-shaped connecting frame can effectively transmit power to the simulated eyeball 3 through the three groups of legs 55, so as to realize the precise rotation movement of the simulated eyeball 3 in the horizontal plane and / or vertical plane.

[0062] In addition, in the embodiment of the present invention, a laser emitter 31 simulating the visual axis is installed at the front center of the shell of each simulated eyeball 3, and the control switch (not shown in the figure) of the laser emitter 31 is set at the rear of the base 1. At the same time, a visual axis target 34 is set on the base 1, just in front of the simulated eyeball 3, and the visual axis target 34 can project and display the laser visual axis and movement trajectory emitted by the laser emitter 31. Through the above settings, the visual axis changes of the simulated eyeball 3 during the movement process can be intuitively observed, providing a clearer and more accurate visualization tool for ophthalmic teaching and research.

[0063] In the embodiment of the present invention, the electric control model also includes a control circuit board arranged inside the housing base 1, and the input end of the control circuit board is connected to the external power supply through a power adapter, thereby ensuring a stable power supply; the output end of the control circuit board is electrically connected to the first servo 51, the second servo 53 and the laser emitter 31 respectively, to provide the required power for them. It should be noted that the laser emitter 31 can be directly powered by an external power supply, and the start and stop can be controlled by the control switch behind the base 1; or it can be indirectly powered by a power adapter and a control circuit board, and the start and stop of the laser emitter 31 can be realized by remotely controlling the circuit board.

[0064] In addition, if Figure 7 , 10 As shown, the electric control model of the embodiment of the present invention is also equipped with a remote controller 10, which is a wireless remote controller connected to the single-chip microcomputer provided on the control circuit board through a communication method. A signal transmitting module is provided in the remote controller, and the signal transmitting module can be an infrared signal transmitting module, a Bluetooth signal transmitting module, or a radio frequency signal transmitting module, etc.; correspondingly, a matching signal receiving module is provided on the control circuit board, such as an infrared signal receiving module, a Bluetooth signal receiving module, or a radio frequency signal receiving module, etc.

[0065] Specifically, the remote controller 10 includes a left joystick 101 and a right joystick 102 on the housing of the remote controller. Both joysticks can move spherically within a certain range. The left joystick 101 corresponds to controlling the simulated left eyeball 31, and the right joystick corresponds to controlling the simulated right eyeball 32. The movements of the two joysticks correspond to controlling the movements of the two simulated eyeballs 3. In addition, a display screen 103 and four buttons are provided on the remote controller 10. The four buttons are, from left to right, a "mode" selection button 104, a "+" button 105, a "-" button 106, and a "save / send" button 107. Among them, button 1 "mode" can be switched between three modes: synchronization, independence, and data. In the mode-synchronization, rotating any joystick will cause the two simulated eyeballs 3 to move in the same direction; in the mode-independence, rotating a certain joystick will point to a specific movement of the corresponding simulated eyeball 3; in the mode-synchronization / independence, the eyeball is assigned to a specific position by using the joystick, and the data number to be recorded is selected by using buttons 105 and 106, and this position is saved as a specific number by using button 107. In the mode - data, a specific number that has been saved is selected by pressing buttons 105 and 106, and "Save / Send" is pressed by pressing button 107 to make the simulated eyeball 3 perform a specific movement according to the movement position recorded by the number.

[0066] From the above content, it can be seen that the electronic control model of the embodiment of the present invention has two modes: manual control and automatic control. Among them, automatic control means recording the movement trajectory of the simulated eyeball 3 in advance and numbering it according to the use requirements. When it is needed, a specific eyeball movement is retrieved by inputting the number. Specifically, when the remote controller 10 issues an automatic control command, the signal transmitting module sends the command signal. After the signal receiving module on the control circuit board receives the command signal, it transmits it to the single-chip microcomputer for processing. The single-chip microcomputer outputs the corresponding control signal to control the first steering gear 51 and / or the second steering gear 53 according to the received command signal through a pre-written control program (this is the prior art and will not be repeated here), so that the simulated eyeball 3 automatically performs the corresponding action; or through the left remote control rod 101 and / or the right remote control rod 102 of the remote controller 10, manually rotate the handle to control the simulated eyeball 3 to move in the corresponding direction, and after the movement is completed, the left remote control rod 102, the right remote control rod 102 and the simulated eyeball 3 return to the starting position. This design allows the user to conveniently operate the electronically controlled model through the remote controller 10, thereby achieving the movement of the simulated eyeball 3 and the control of the laser emitter 31, providing a more convenient and flexible tool for ophthalmic teaching and research.

[0067] The electric control model provided by the present invention has at least the following simulation functions: 1. It can simulate the eye movement of the right eye or the left eye or the simultaneous movement of both eyes when each extraocular muscle contracts; 2. It can simulate the binocular movement during concomitant esotropia; 3. It can simulate the binocular movement during concomitant exotropia; 4. It can simulate the binocular movement during paralytic exotropia; 5. It can simulate the binocular movement during paralytic esotropia.

[0068] Example 2

[0069] The only difference between this embodiment and embodiment 1 is that the six ligaments in the ligament group 6 are made of elastic materials, such as springs. The selection of such elastic materials enables the six ligaments to more realistically exhibit elasticity and contraction characteristics during the movement of the human extraocular muscles. When simulating the movement of the eyeball 3, the elastic ligaments can be stretched and contracted accordingly according to different movement directions and strengths, better simulating the dynamic changes of the human extraocular muscles in actual movement.

[0070] Specifically, in the embodiment of the present invention, the ends of the six elastic ligaments connected to the simulated eyeball 3 are exactly the same as those in the above-mentioned embodiment 1, and the other ends of the first ligament 61, the second ligament 62, the third ligament 63, the fourth ligament 64 and the fifth ligament 65 respectively pass through the through holes pre-opened at the rear of the simulated orbit frame 2 and are fixedly connected to the inner wall of the first support shell 7 arranged near the inner side of the simulated orbit frame 2, and the other end of the sixth ligament 66 is fixedly arranged on the inside of the second support shell 8 between the two simulated eyeballs 3. And when the simulated eyeball 3 does not move (that is, the simulated eyeball 3 is in the front view position), the six elastic ligaments are in a natural state.

[0071] The above description is only a specific embodiment of the present invention, so that those skilled in the art can understand or implement the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention.

[0072] It should be understood that the present invention is not limited to what has been described above and that various modifications and changes may be made without departing from its scope. The scope of the present invention is limited only by the appended claims.
