Description

Technical Field

[0001] The utility model belongs to the technical field of ophthalmology teaching auxiliary tools, and in particular relates to an electric control model for simulating the movement of human eyeballs and extraocular muscles. Background Art

[0002] In the field of ophthalmology teaching, it is crucial 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 a crucial role in the human visual system. Through different types of movements such as saccades, pursuits, and micro-saccades, the eyeballs can quickly focus on objects of interest, 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, and medial rectus D; and two oblique muscles: superior oblique E and inferior oblique F. These six muscles are interlaced and arranged around the eyeball, with their spatial location being extremely complex. Under the precise control of the nervous system, these muscles contract and relax to change the position of the eyeball, enabling precise eye movement in different directions. Any dysfunction of the extraocular muscles can lead to abnormal eye movements, such as strabismus and diplopia. In short, the complex and precise process of eye and extraocular muscle movement is crucial to our visual function.

[0003] However, the current traditional ophthalmology teaching method mainly uses diagrams and models, which have the following defects in practice: First, the diagram method relies on flat images in books and teachers' oral explanations to impart knowledge. This method is relatively abstract, making it difficult for students to intuitively experience the actual process of eye movement and the specific role of the extraocular muscles, which in turn leads to great difficulties in their understanding of the complex physiological structure and movement principles of the eye; Second, the existing teaching models can only display the static structure of the eyeball and cannot dynamically simulate the control of the extraocular muscles on the movement of the two eyes. In other words, there is a lack of accurate description of the relationship between the eyeball and the extraocular muscles in the moving state, which makes it difficult to meet the high requirements of modern ophthalmology teaching for intuitiveness and interactivity. In addition, the existing public models, such as the model shown in the Chinese patent application number CN214312337U, entitled "A Multifunctional Human Eye Model for Teaching Demonstration", can simulate the process of the muscles in the eyeball adjusting the lens, but cannot show the relationship between eye movement and extraocular muscle movement.

[0004] In view of the above situation, this utility model is proposed to provide a more effective auxiliary tool for ophthalmology teaching. Utility Model Content

[0005] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide an electrically controlled model that simulates the movement of human eyeballs and extraocular muscles. It is mainly used to solve the problem faced in current ophthalmology teaching that the movement process of the eyeballs and extraocular muscles cannot be clearly and intuitively displayed, and it is difficult to accurately present the complex antagonistic or synergistic relationship between the extraocular muscles, which brings great inconvenience to teaching work. The present invention assists ophthalmology teaching through precise simulation and intuitive display, so that students can have a deeper understanding of the movement principles and interaction relationships of the human eyeballs and extraocular muscles.

[0006] The purpose of this utility model is to solve the problem through the following technical solutions:

[0007] The utility model provides an electrically controlled model for simulating the movement of human eyeballs and extraocular muscles, comprising a base, two simulated eye socket frames symmetrically arranged on the surface of the base, each of which houses a spherical shell-shaped simulated eyeball, and a support bracket fixedly arranged on the surface of the base within each simulated eye socket frame. A drive assembly is provided at one end of the support bracket extending into the simulated eyeball, the drive assembly being fixedly connected to the simulated eyeball for driving the simulated eyeball to perform rotational movement in the horizontal and / or vertical planes.

[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 other ends of the first ligament, the second ligament, the third ligament, the fourth ligament and the fifth ligament away from the simulated eyeball are respectively arranged in a first supporting shell near the inner side of the rear of the simulated orbital frame, and the other end of the sixth ligament away from the simulated eyeball is arranged in a second supporting shell between the two simulated eyeballs.

[0009] Furthermore, the drive assembly is arranged inside the simulated eyeball, including a first servo fixedly connected to the support 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.

[0010] 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 legs, and the multiple groups of legs are distributed around the gate-shaped connecting frame.

[0011] 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 provided on the base, directly in front of the simulated eyeball. The visual axis target is used to project and display the laser visual axis and movement trajectory emitted by the laser emitter.

[0012] Furthermore, the base is a shell structure, in which a control circuit board is arranged, the input end of the control circuit board is connected to the external power supply through a power adapter, and the output end of the control circuit board is electrically connected to the first servo, the second servo and the laser transmitter respectively;

[0013] Alternatively, the laser emitter is directly connected to an external power supply, and a switch for independently controlling the laser emitter is provided at the rear of the base.

[0014] Furthermore, the electronically controlled model further comprises a remote controller, which is connected to a single chip microcomputer provided on the control circuit board via a communication method;

[0015] Wherein, a signal transmitting module is provided in the remote control, and the signal transmitting module includes an infrared signal transmitting module, a Bluetooth signal transmitting module or a radio frequency signal transmitting module, and a matching signal receiving module is provided on the corresponding control circuit board;

[0016] 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 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 corresponding control signals 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 stick and / or the right remote control stick 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 stick, the right remote control stick and the simulated eyeball return to the starting position.

[0017] Furthermore, the simulated orbital frame is made of transparent material.

[0018] Furthermore, the six ligaments in the ligament group are all made of elastic material, and the ends of the six ligaments away from the simulated eyeball are fixedly connected to the inner wall of the first support shell or the second support shell, and when the simulated eyeball does not move, the six ligaments are in a naturally stretched state.

[0019] Furthermore, the six ligaments in the ligament group are all made of non-elastic material, and the ends of the six ligaments away from the simulated eyeball are all equipped with plumb bobs of a certain weight. The first support shell and the second support shell are both fixedly provided with cross bar connectors, and rollers are rotatably provided on the cross bar connectors. The six ligaments equipped with plumb bobs are correspondingly arranged on the rollers of the first support shell or the second support shell.

[0020] Furthermore, 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, the fourth ligament is connected to the inner center of the simulated eyeball, the fifth ligament is connected to the outer upper part of the simulated eyeball, and the sixth ligament is connected to the outer lower part of the simulated eyeball;

[0021] A U-shaped slide is provided on the second supporting shell, and the end of the fifth ligament away from the upper outer part of the simulated eyeball passes through the U-shaped slide and is then provided in the first supporting shell.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The electronically controlled model provided by this utility model, which simulates the movement of the human eyeballs and extraocular muscles, is primarily composed of a base, a simulated orbital frame, a simulated eyeball, a support bracket, a drive assembly, and six ligaments disposed on the exterior of the simulated eyeball. The simulated orbital frame is made of a transparent material, and the drive assembly primarily consists of two stacked servos, which can be controlled via a remote control. Compared to existing technologies, this model has at least the following advantages:

[0024] First, it provides an auxiliary teaching function. Compared with traditional diagrammatic methods, this model can intuitively demonstrate the movement and changes of the eyeball and extraocular muscles. This allows students to go beyond abstract flat images and verbal explanations, thereby gaining a deeper understanding of the actual eye movements and the specific functions of the extraocular muscles, greatly improving teaching effectiveness. Second, by accurately presenting the complex antagonistic or synergistic relationships between the extraocular muscles (six ligaments), it helps students better understand the eye movement abnormalities that may be caused by extraocular muscle dysfunction, laying a solid foundation for future clinical practice.

[0025] Secondly, from a functional and operational perspective, the electronic control design makes operation extremely convenient. Remote operation is possible by connecting a remote control to the control circuit board, meeting the needs of different scenarios. The two servos in the drive assembly work together to accurately simulate the rotational movement of the eyeball in the horizontal and / or vertical planes, presenting a variety of realistic eye movement states. Furthermore, various types of strabismus can be simulated through program control, deepening students' understanding of the disease. At the same time, the installation of a laser transmitter and visual axis target clearly displays the laser visual axis and movement trajectory, enhancing the intuitiveness of teaching. The simulated orbital frame is made of a transparent material, which has a certain degree of transparency to facilitate observation of the internal structure and is also durable. The ligaments can be selected as elastic or fixed types, and are equipped with corresponding auxiliary devices to provide a variety of demonstration methods for teaching to meet the needs of different teaching content.

[0026] In summary, this new electronically controlled model can dynamically simulate the movement of both eyes and their extraocular muscles, accurately depicting the relationship between the eyes and extraocular muscles during movement, meeting the high demands of modern ophthalmology teaching for intuitiveness and interactivity. Compared to existing publicly available models, its structure is relatively simple, and it intuitively depicts the relationship between the eye and extraocular muscles, avoiding the operational and comprehension difficulties associated with complex structures, significantly facilitating ophthalmology teaching.

[0047] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of devices consistent with certain aspects of the present invention as detailed in the appended claims.

[0048] 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 with reference to the accompanying drawings and embodiments.

[0049] Example 1

[0050] See also Figures 2 to 7The present invention provides an electrically controlled model that simulates the movement of both human eyes and extraocular muscles. The model comprises a base 1 in the form of a shell, with two simulated orbital frames 2 symmetrically arranged on its surface at a vertical interface (or, alternatively, the two simulated orbital frames 2 are integrated and separated by a baffle). Each simulated orbital frame 2 houses a spherical shell-shaped simulated eye 3 (with an opening at the rear), comprising a simulated left eye 31 and a simulated right eye 32. Furthermore, a support bracket 4 is fixedly mounted on the surface of each simulated orbital frame 2. A drive assembly 5 is mounted on one end of each simulated orbital frame 2, extending from the opening into the shell of the simulated eye 3. The output end of the drive assembly 5 is fixedly connected to the corresponding simulated eye 3, driving the simulated eye 3 to rotate horizontally and / or vertically. Preferably, the drive assembly 5 can control the movement of the simulated eye 3 individually or in a coordinated manner. Furthermore, the present invention provides a ligament assembly 6 simulating human extraocular muscles at a specific location on the exterior of each simulated eye 3. It can be seen from this that the electronically controlled 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 cooperative relationship between the ligament groups 6.

[0051] It is important to note that in this embodiment of the present invention, the simulated orbital frame 2 is made of a transparent material, such as glass or acrylic, allowing the user to clearly observe the movements of the eyeballs and extraocular muscles within the electronically controlled model, providing a more intuitive perspective for ophthalmic teaching and research. Furthermore, the simulated orbital frame 2, simulated eyeball 3, support bracket 4, drive assembly 5, and ligament assembly 6, mounted on the surface of the base 1, are mirrored (symmetrically) with respect to the perpendicular interface of the base 1, accurately simulating the structure of the human eye. This design ensures that the model's appearance and functionality closely resemble those of real human eyes, providing a more accurate and intuitive tool for ophthalmic teaching and research.

[0052] Specifically, such as Figure 3As shown, 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 point 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 the 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 .

[0053] In the embodiment of the present invention, the six ligaments in the ligament group 6 are all made of non-elastic material, 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 is rotatably provided on the crossbar connector 9 (such as Figure 5 、 6 (As shown), the design of roller 91 allows the ligaments to slide more smoothly during movement, reducing frictional resistance. The first, second, third, fourth, and fifth ligaments 61, 62, 63, 64, and 65, each equipped with a plumb bob, are mounted on roller 91 within first support housing 7. The sixth ligament 66, also equipped with a plumb bob, is mounted on roller 91 within second support housing 8. When simulating eye movement, these ligaments slide on roller 91, simulating the contraction and extension of the extraocular muscles.

[0054] like Figure 3As shown, in the embodiment of the present invention, the drive assembly 5 is completely disposed inside the simulated eyeball 3. The drive assembly 5 includes a first servo 51 fixedly connected to the support bracket 4. The output shaft of the first servo 51 is vertically arranged. A mounting bracket 52 is fixedly connected to the output shaft of the first servo 51. The mounting bracket 52 serves as a load-bearing component and is fixedly mounted on the second servo 53. The output shaft of the second servo 53 is horizontally arranged and cooperates with the output shaft of the first servo 51 to achieve precise control of the movement of the simulated eyeball 3. A connecting bracket 54 is fixedly disposed on the output shaft of the second servo 53. The connecting bracket 54 is fixedly connected to the inner wall of the simulated eyeball 3 via multiple sets of legs 55. By cleverly stacking the two servos in different directions, the first servo 51 can drive the second servo 53 and the simulated eyeball 3 to rotate along the horizontal plane; at the same time, the second servo 53 can drive the simulated eyeball 3 to rotate along the vertical plane. In other words, through the coordinated cooperation of the two servos, the simulated eyeball 3 can be accurately rotated in the horizontal and / or vertical planes. 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 angle of inclination of the two servos is not specifically limited in this invention.

[0055] The connecting frame 54 employed in the embodiment of the present invention is a gate-shaped connecting frame. This gate-shaped connecting frame is connected to the simulated eyeball 3 via multiple sets of legs 55. For example, in this embodiment, three sets are provided, each with two legs 55 arranged side by side. These three sets of legs 55 are respectively disposed on both sides and the top of the gate-shaped connecting frame, and are fixedly connected to the inner sides and top of the simulated eyeball 3, respectively, thereby ensuring a more stable connection. Under the action of the drive assembly 5, the gate-shaped connecting frame can effectively transmit power to the simulated eyeball 3 through these three sets of legs 55, achieving precise rotational movement of the simulated eyeball 3 in the horizontal and / or vertical planes.

[0056] Furthermore, in this embodiment of the present invention, a laser emitter 31 simulating the visual axis is mounted at the front center of the housing of each simulated eyeball 3. A control switch (not shown) for this laser emitter 31 is located behind the base 1. Furthermore, a visual axis target 34 is located on the base 1, directly in front of the simulated eyeball 3. This target projects and displays the visual axis and motion trajectory of the laser emitted by the laser emitter 31. This arrangement allows intuitive observation of changes in the visual axis of the simulated eyeball 3 during movement, providing a clearer and more accurate visualization tool for ophthalmic teaching and research.

[0057] In an embodiment of the present invention, the electronically controlled model further includes a control circuit board disposed within the housing base 1. The input end of the control circuit board is connected to an external power source via 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 them with the required power. It should be noted that the laser emitter 31 can be powered directly by an external power source and started and stopped by a control switch on the rear of the base 1; or it can be powered indirectly by a power adapter and the control circuit board, and the laser emitter 31 can be started and stopped by remotely controlling the circuit board.

[0058] In addition, if Figure 7 As shown, the electronically controlled model of the present embodiment is further equipped with a remote controller 10. This remote controller 10 is a wireless remote controller that is connected to the single-chip microcomputer on the control circuit board via a communication method. The remote controller includes a signal transmitting module, which may be an infrared signal transmitting module, a Bluetooth signal transmitting module, or a radio frequency signal transmitting module. Correspondingly, a matching signal receiving module, such as an infrared signal receiving module, a Bluetooth signal receiving module, or a radio frequency signal receiving module, is provided on the control circuit board.

[0059] Specifically, the remote control 10 includes a left joystick 101 and a right joystick 102 on the remote housing. Both joysticks can move spherically within a certain range. The left joystick 101 controls the simulated left eye 31, and the right joystick controls the simulated right eye 32. Movement of the two joysticks corresponds to the movement of the two simulated eyes 3. Furthermore, the remote control 10 also includes a display screen 103 and four buttons. From left to right, the four buttons are: a "mode" selection button 104, a "+" button 105, a "-" button 106, and a "save / send" button 107. Button 1, "mode," switches between three modes: synchronous, independent, and data. In the synchronous mode, rotating either joystick causes the two simulated eyes 3 to move in the same direction. In the independent mode, rotating a joystick directs the corresponding simulated eye 3 to a specific movement. In the synchronous / independent mode, the joysticks are used to specify an eye position. The data number to be recorded is selected using buttons 105 and 106, and the position is saved as a specific number using button 107. In the mode - data, use buttons 105 and 106 to select a specific number that has been saved, and use button 107 "Save / Send" to make the simulated eyeball 3 perform a specific movement according to the movement position recorded by the number.

[0060] As can be seen from the above, the electronically controlled model of the present invention has two modes of control: manual and automatic. Automatic control involves recording and numbering the movement trajectory of the simulated eye 3 in advance, based on user needs. When needed, the user can access a specific eye movement by inputting the number. Specifically, when the remote controller 10 issues an automatic control command, the signal transmitting module transmits a command signal. The signal receiving module on the control circuit board receives the command signal and transmits it to the single-chip microcomputer for processing. Based on the received command signal, the single-chip microcomputer, using a pre-programmed control program (this is prior art and will not be described in detail here), outputs a corresponding control signal to control the first servo 51 and / or the second servo 53, causing the simulated eye 3 to automatically perform the corresponding movement. Alternatively, the left and / or right remote control sticks 101 and 102 of the remote controller 10 can be manually rotated to control the movement of the simulated eye 3 in the corresponding direction. After the movement is completed, the left and right remote control sticks 102 and 102, and the simulated eye 3, return to their starting positions. This design allows the user to conveniently operate the electronically controlled model through the remote control 10 to achieve 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.

[0061] The electronically controlled 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.

[0062] Example 2

[0063] This embodiment differs from Example 1 only in that the six ligaments in ligament set 6 are all made of an elastic material, such as a spring. This choice of elastic material allows the six ligaments to more realistically exhibit elasticity and contraction properties during the simulation of human extraocular muscle movement. When simulating eyeball 3 movement, the elastic ligaments can stretch and contract accordingly based on the direction and force of movement, better simulating the dynamic changes of human extraocular muscles during actual movement.

[0064] Specifically, in this embodiment of the present invention, the ends of the six elastic ligaments connected to the simulated eyeball 3 are located in exactly the same position as in the first embodiment described above. The other ends of the first, second, third, fourth, and fifth ligaments 61, 62, 63, 64, and 65 pass through pre-cut holes in the rear of the simulated orbital frame 2 and are fixedly connected to the inner wall of the first support shell 7, located near the inner side of the simulated orbital frame 2. The other end of the sixth ligament 66 is fixedly mounted on the interior of the second support shell 8 between the two simulated eyeballs 3. When the simulated eyeball 3 is not moving (i.e., in the emmetropia position), the six elastic ligaments are in a natural state.

[0065] The above description is merely a specific embodiment of the present invention, which enables those skilled in the art to 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 may be implemented in other embodiments without departing from the spirit or scope of the present invention.

[0066] It should be understood that the present invention is not limited to the above description and that various modifications and changes can be made without departing from the scope of the present invention. The scope of the present invention is limited only by the appended claims.
