Description

Technical Field

[0001] The present invention relates to the field of ophthalmology teaching, and particularly relates to an eyeball model device for teaching. Background Art

[0002] When conducting ophthalmology-related teaching and training, due to the complex structure of the eyeball, in order to facilitate students' understanding and mastery of ophthalmology knowledge, instructors often use an eyeball model to explain ophthalmology knowledge during lectures. Due to the large number of people in the classroom, when the instructor uses the eyeball model on the podium to explain knowledge points, students in the back row are difficult to clearly distinguish the position on the eyeball model pointed out by the instructor when explaining the current knowledge point. Especially for novice students, this is likely to cause students to have difficulty understanding or even misunderstanding the knowledge points, which is not conducive to students' learning and mastering of the eyeball structure and the pathological characteristics of related diseases, resulting in poor teaching quality. Summary of the Invention

[0003] Aiming at the deficiencies of the existing technology, the present invention proposes an eyeball model device for teaching, so that students can clearly see the specific position pointed out by the instructor on the eyeball model when explaining knowledge points, facilitating students to correctly learn and master the eyeball structure and the pathological characteristics of related diseases, and improving teaching quality.

[0004] The purpose of the present invention is achieved through the following technical solutions:

[0005] An eyeball model device for teaching provided by the present invention includes:

[0006] A base, on the top of which a support member is installed;

[0007] A transparent spherical shell, installed on the support member and suspended above the base;

[0008] An eyeball model, which includes an eyeball part and an optic nerve part. The eyeball model is located inside the transparent spherical shell, its optic nerve part is connected to the inner wall of the transparent spherical shell, and there is a gap between its eyeball part and the inner wall of the transparent spherical shell; and

[0009] An indicating mechanism, installed on the transparent spherical shell and capable of moving arbitrarily on the outer surface of the transparent spherical shell. A camera and an indicator are installed on the indicating mechanism. The camera is externally connected to a display, and the indicator can project light into the transparent spherical shell.

[0010] Further, the support member is a telescopic column capable of adjusting its length.

[0011] Further, a hole is provided on one side of the transparent spherical shell, and a sleeve extending outward is installed at the hole. One side of the sleeve is fixedly connected to the top end of the support member.

[0012] Further, the eyeball model is cut in half longitudinally into a fixed part and a movable part. Both the fixed part and the movable part have an eyeball portion and an optic nerve portion. The fixed part is a hollow shell with an open cut surface. The optic nerve portion of the fixed part is fixedly connected to the edge of the orifice. The cut surface of the movable part is drawn with a sectional view of the internal structure of the human eyeball. At one end of the optic nerve portion of the movable part away from the eyeball portion, a rotating column is provided. The rotating column is axially rotatably installed in the sleeve through the orifice. Rotating the rotating column can rotate the movable part into the interior of the fixed part and display the sectional view of the internal structure of the human eyeball outward, or align the cut surfaces of the movable part and the fixed part to form a complete eyeball.

[0013] Further, one end of the rotating column away from the eyeball model is located outside the sleeve, and a knob is provided at this end.

[0014] Further, the indicating mechanism further includes an inner connecting block, an outer connecting block and a movable assembly. The inner connecting block is located inside the transparent spherical shell and the outer connecting block is located outside the transparent spherical shell. The inner connecting block and the outer connecting block are connected by magnetic attraction. The movable assembly is installed on the outer connecting block. The camera and the indicator are installed on the movable assembly.

[0015] Further, the movable assembly includes a rotating seat, a travel column, a movable sleeve and a mounting block. The rotating seat is axially rotatably installed on the outer connecting block. One end of the travel column is hinged to the rotating seat. The movable sleeve is slidably sleeved on the travel column. The mounting block is hinged to one side of the movable sleeve. The camera and the indicator are both installed on the mounting block in the same direction.

[0016] Further, the surface of the inner connecting block in contact with the transparent spherical shell is an outwardly convex curved surface adapted to the inner wall of the transparent spherical shell, and the surface of the outer connecting block in contact with the transparent spherical shell is an inwardly concave curved surface adapted to the outer wall of the transparent spherical shell.

[0017] As can be seen from the above technical solutions, for an eyeball model device for teaching provided by the present invention, when a lecturer is conducting ophthalmology teaching and needs to point out the corresponding position of the eyeball, the indicating mechanism can be moved to the position corresponding to the eyeball model of the transparent spherical shell, and the visual field of the camera and the indicating position of the indicator light can be adjusted through the movable assembly. The visual field image at the irradiated position of the indicator is transmitted to the display through the camera and presented, which is beneficial for all students to clearly see the specific position pointed out by the lecturer on the eyeball model when explaining the knowledge points, facilitating the students to correctly learn and master the eyeball structure and the pathological characteristics of related diseases, and improving the teaching quality; by rotating the movable part, it is possible to choose to display the sectional view of the internal structure of the human eyeball outward or align the cut surfaces of the movable part and the fixed part to form a complete eyeball, which is convenient for the lecturer to explain the overall structure of the human eyeball through this device and improve the teaching efficiency.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only embodiments.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this invention belongs. The terms used in the description of the present invention herein are for the purpose of describing specific embodiments only and are not intended to limit the present invention.

[0030] As Figures 1 - 3 shown, a teaching eyeball model device provided in this embodiment includes a base 1, a transparent spherical shell 2, an eyeball model 3, and an indicating mechanism 4.

[0031] Please refer to Figure 1 , a support member 11 is installed on the top of the base 1 for providing support for the transparent spherical shell 2. To facilitate better display of the eyeball model 3 during teaching, preferably, the support member 11 is a telescopic column capable of adjusting its length.

[0032] Please refer to Figure 1 and Figure 2 , the transparent spherical shell 2 is installed on the support member 11 and suspended above the base 1 so that the indicating mechanism 4 can point to any position of the eyeball model 3 on the transparent spherical shell 2. Specifically, a hole 21 is provided on one side of the transparent spherical shell 2, and a sleeve 22 extending outward is installed at the hole 21, and one side of the sleeve 22 is fixedly connected to the top end of the support member 11.

[0033] The transparent spherical shell 2 can be made of transparent materials such as colorless transparent plastic or glass. To prevent the transparent spherical shell 2 from being scratched and to prevent the external observation field of view from being blocked, the material of the transparent spherical shell 2 is preferably glass.

[0034] Please refer to Figures 1 - 3 , the eyeball model 3 refers to the human eyeball structure and includes an eyeball part and an optic nerve part. The eyeball model 3 is located inside the transparent spherical shell 2. The optic nerve part of the eyeball model 3 is connected to the inner wall of the transparent spherical shell 2. By using the optic nerve part extending outside the eyeball part as a connection point and reasonably utilizing the structure of the eyeball model 3, additional connecting components are reduced, making the structure of the device more concise. There is a gap between the eyeball part of the eyeball model 3 and the inner wall of the transparent spherical shell 2, which is convenient for the indicating mechanism 4 to point out the position and provides an observation field of view.

[0035] When lecturers explain ophthalmological knowledge, more often they need to explain the internal structure of the eyeball. Therefore, as Figures 1 - 3As shown, in one embodiment, in order to enable the eyeball model 3 to reflect the internal structure of the eyeball and facilitate teaching, the eyeball model 3 is cut in half longitudinally from the middle into a fixed part 31 and a movable part 32. Both the fixed part 31 and the movable part 32 have an eyeball part and an optic nerve part. The fixed part 31 is a hollow shell with an open cut surface, and the optic nerve part of the fixed part 31 is fixedly connected to the edge of the orifice 21. The space inside the fixed part 31 is used to accommodate the movable part 32. Therefore, the overall size of the fixed part 31 will be slightly larger than that of the movable part 32. To ensure the overall aesthetics of the eyeball model 3, the wall thickness of the fixed part 31 should be as thin as possible. At the same time, to take into account the overall strength of the fixed part 31 and make it not easily deformed, the fixed part 31 can be made of a metal material. A sectional view of the internal structure of the human eyeball 321 is drawn on the cut surface of the movable part 32. At one end of the optic nerve part of the movable part 32 away from the eyeball part, a rotating column 322 is provided. The rotating column 322 is axially rotatably installed in the sleeve 22 through the orifice 21. Rotating the rotating column 322 can rotate the movable part 32 into the interior of the fixed part 31 and display the sectional view of the internal structure of the human eyeball 321 outward, or align the cut surface of the movable part 32 with that of the fixed part 31 to form a complete eyeball. By simply rotating the rotating column 322, the state of the eyeball model 3 can be quickly switched, which is beneficial for the lecturer to explain the internal structure and external structure of the eyeball respectively and improve the teaching efficiency.

[0036] Preferably, one end of the rotating column 322 away from the eyeball model 3 is located outside the sleeve 22, and a knob 323 is provided at this end to facilitate rotating the rotating column 322.

[0037] Please refer to Figures 1 - 3 , the indicating mechanism 4 is installed on the transparent spherical shell 2 and can move arbitrarily on the outer surface of the transparent spherical shell 2. A camera 41 and an indicator 42 are installed on the indicating mechanism 4. The camera 41 is externally connected to a display to present the internal situation of the transparent spherical shell 2 at the position where the indicating mechanism 4 is located through the display. The indicator 42 can project light into the transparent spherical shell 2. The indicator 42 can specifically be an infrared indicator to clearly point out the position.

[0038] As Figure 2As shown, the indicating mechanism 4 further includes an inner connection block 43, an outer connection block 44, and a movable assembly 45. The inner connection block 43 is located inside the transparent spherical shell 2, and the outer connection block 44 is located outside the transparent spherical shell 2. The inner connection block 43 and the outer connection block 44 are connected by magnetic attraction. Specifically, magnetic members are provided on the sides of the inner connection block 43 and the outer connection block 44 close to each other, and magnets can be specifically selected. The movable assembly 45 is installed on the outer connection block 44. The movable assembly 45 includes a rotating seat 451, a travel column 452, a movable sleeve 453, and a mounting block 454. The rotating seat 451 is axially rotatably installed on the outer connection block 44. One end of the travel column 452 is hinged to the rotating seat 451. The movable sleeve 453 is slidably sleeved on the travel column 452. The mounting block 454 is hinged to one side of the movable sleeve 453. The camera 41 and the indicator 42 are both installed on the mounting block 454 facing the same direction.

[0039] During specific use, the entire indicating mechanism 4 can be moved and fixed to any surface of the transparent spherical shell 2 by the attraction between the inner connection block 43 and the outer connection block 44. By operating such as rotating the rotating seat 451, moving the movable sleeve 453, and rotating the mounting block 454, the viewing field of the camera 41 and the indicating position of the light of the indicator 42 can be adjusted at will. It has a high degree of freedom and can be adjusted at any angular position, which is beneficial for the external display to provide a clearer and broader model viewing field for the trainees, deepen the learning impression of the trainees, and thus improve the teaching quality.

[0040] It should be noted that the rotating seat 451, the travel column 452, the movable sleeve 453, and the mounting block 454 can maintain their current states unchanged when not forced to move.

[0041] Preferably, the surface of the inner connection block 43 in contact with the transparent spherical shell 2 is an outward convex curved surface adapted to the inner wall of the transparent spherical shell 2, and the surface of the outer connection block 44 in contact with the transparent spherical shell 2 is an inward concave curved surface adapted to the outer wall of the transparent spherical shell 2. This is beneficial to increase the magnetic contact surface between the inner connection block 43 and the outer connection block 44, increase the suction force, and thus improve the stability of the indicating mechanism 4 to maintain its current position. Moreover, it can reduce the angular contact between the inner connection block 43 and the outer connection block 44 and the inner and outer surfaces of the transparent spherical shell 2, preventing the transparent spherical shell 2 from being scratched.

[0042] An eyeball model device for teaching provided by the present invention. When a lecturer is conducting ophthalmology teaching and needs to point out the corresponding position of the eyeball, the movable indicating mechanism 4 can be moved to the position corresponding to the eyeball model 3 of the transparent spherical shell 2, and the viewing field of the camera 41 and the indicating position of the light of the indicator 42 can be adjusted through the movable assembly 45. The visual field image at the irradiated position of the indicator 42 is transmitted to the display through the camera 41 and presented, which is beneficial for all students to clearly see the specific position pointed out on the eyeball model when the lecturer explains the knowledge points, facilitating the students to correctly learn and master the eyeball structure and the pathological characteristics of related diseases, and improving the teaching quality; by rotating the movable part 32, it is possible to select to display the sectional view 321 of the internal structure of the human eyeball outward or to align the movable part 32 with the sectional plane of the fixed part 31 to form a complete eyeball, which is convenient for the lecturer to explain the overall structure of the human eyeball through this device and improve the teaching efficiency.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the various embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
