Description

Technical Field

[0001] This utility model relates to the field of medical accessory technology, specifically to an ophthalmic simulation teaching device. Background Technology

[0002] Ophthalmology education is a crucial component in training professional ophthalmologists, and its core lies in the close integration of theoretical knowledge and clinical practice. Teaching typically begins with basic anatomy, physiology, and optical principles to help students build a solid theoretical foundation. Subsequently, students learn essential skills such as slit-lamp examination, funduscopy, and intraocular pressure measurement through simulation training and clinical clerkships.

[0003] In ophthalmology teaching, educational models play a crucial role, helping medical students and physicians to more intuitively understand eye structure and master clinical skills. Anatomical models of the eyeball are used to learn about the various layers of the eye (such as the cornea, iris, lens, and retina), enhancing spatial cognitive abilities. Current eyeball models are commonly static and fixed, often with a semi-sectional structure. While these aid in understanding and recognizing the different layers, they cannot simulate retinal diseases in practical use. Explaining pathology relies on the lecturer's verbal description, making it difficult for students to intuitively grasp the complex pathological changes. Furthermore, the components of the model cannot be separated, requiring students to point to specific locations when explaining a particular component, which hinders their concentration. Therefore, there is room for improvement in this technology. Utility Model Content

[0004] This invention aims to solve the problems mentioned above, namely, that static fixed models cannot be used to simulate retinal diseases in actual use, and that the components cannot be separated and removed, by providing an ophthalmic simulation teaching device.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: an ophthalmic simulation teaching device, including a magnetically connected support and an eyeball assembly; the eyeball assembly includes a hemisphere one and a hemisphere two; the hemisphere one and the hemisphere two, from the outside to the inside, include the sclera, the choroid, and the retina respectively;

[0006] The retina has several tree-like grooves, and a network of retinal blood vessels is distributed on the retina. The grooves can accommodate the retinal blood vessels.

[0007] Both hemisphere one and hemisphere two have a detachable front end assembly on their front sides. The front end assembly includes a lens and a corneal portion. A connection structure is provided between the front end assembly and hemisphere one and hemisphere two.

[0008] It is also provided with an indicator component; the indicator component includes a lamp wire (21) provided in each branch of the bottom surface of the strip groove (9), a number of lamp beads are connected in parallel on the lamp wire, and a switch connected to the corresponding lamp wire is provided next to each branch of the strip groove.

[0009] Furthermore, the support includes a base, a column, and a support portion; the bottom surface of the support portion is provided with a magnetic absorbing piece, and the lower end of the eyeball assembly is provided with a second magnetic absorbing piece corresponding to the magnetic absorbing piece.

[0010] Furthermore, the strips intersect and penetrate each other.

[0011] Furthermore, the rear end of the eyeball assembly is connected to an outlet tube, through which the retinal blood vessels converge and pass; the outlet tube contains an optic nerve that extends into the interior of the eyeball assembly.

[0012] Furthermore, each branch of the retinal blood vessels is coated with a different color.

[0013] Furthermore, the connecting structure includes a semi-circular groove 1 on the front of both hemisphere 1 and hemisphere 2, a circular groove 2 inside the circular groove 1, and a circular groove 3 inside the circular groove 2.

[0014] An annular limiting shoulder 1 is formed between the three circular grooves and the two circular grooves, and an annular limiting shoulder 2 is formed between the two circular grooves and the one circular groove. The front of both the limiting shoulder 2 and the limiting shoulder 1 is provided with a symmetrical arc-shaped magnetic plate 1, and the back of both the lens and the cornea is provided with a magnetic plate 2 that can be magnetically attracted to the magnetic plate 1.

[0015] Furthermore, all of the retinal blood vessels are made of light-transmitting materials.

[0016] The advantages of this utility model compared with the prior art are as follows:

[0017] The retinal blood vessels on the retina can peel off, making it easier for lecturers to explain retinal vascular abnormalities, retinal vein occlusion, and other diseases. The three-dimensional explanation makes it easier for students to understand.

[0018] It features an electrically switchable indicator component that, together with colored retinal blood vessels, allows the entire circuit to be illuminated and translucent. By turning off the switches of some branches, that branch can be extinguished, simulating a blood vessel blockage.

[0019] Both the lens and cornea are magnetically connected, allowing for individual removal to mark and explain specific lesions, thus improving flexibility;

[0020] The entire eyeball assembly is magnetically attached to the support. In actual use, eyeball assemblies with different lesion morphologies can be replaced for further explanation. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] Example 1, in conjunction with Appendix Figure 1 An ophthalmic simulation teaching device, comprising a magnetically connected support and an eyeball assembly;

[0028] The support includes a base 1, a column 2, and a support part 3; the bottom surface of the support part 3 is provided with a magnetic absorbing piece, and the lower end of the eyeball assembly is provided with a magnetic absorbing piece corresponding to the magnetic absorbing piece; so that the entire eyeball assembly is magnetically attached to the support. In actual use, eyeball assemblies with different lesion morphologies can be replaced for further explanation.

[0029] Combined with appendix Figure 1 , 2 4. The eyeball assembly includes hemisphere 1 4 and hemisphere 2 5, which are obtained by longitudinal sectioning of the spheres and are fixed by magnetic attraction of the front end assembly during subsequent fastening; hemisphere 1 4 and hemisphere 2 5 include sclera 6, choroid 7 and retina 8 from the outside to the inside.

[0030] Based on the above structure, a number of tree-shaped grooves 9 are formed on the retina 8. The grooves 9 intersect and penetrate each other. A network of retinal blood vessels 10 are distributed on the retina 8. The grooves 9 can accommodate the retinal blood vessels 10. Thus, the retinal blood vessels 10 can be picked out or detached from the retina 8, which makes it easier for the lecturer to explain retinal vascular abnormalities, retinal vein occlusion and other diseases. The three-dimensional explanation makes it easier for students to understand.

[0031] Based on the above, each branch of the retinal vessels 10 is coated with a different color. Since the blood vessels in a real eye are almost adjacent and the same color, it is difficult to distinguish them instantly during teaching. Therefore, coating the retinal vessels 10 with different stains makes them easier to distinguish and helps students understand the blood supply and pathways of the eye. In addition, the color coating also makes it easier for students to learn and remember various pathological changes. For example, hypertensive retinopathy can be represented by the arteriovenous crossings coated with blue and red, which are shown by the arteriovenous indentations. The red and blue colors make the crossings more conspicuous and easier to remember.

[0032] In addition, an outlet tube 11 is connected to the rear end of the eyeball assembly, through which retinal blood vessels 10 converge and pass. An optic nerve is located inside the outlet tube 11 and extends into the interior of the eyeball assembly.

[0033] Combined with appendix Figure 4 It also includes an indicator component; the indicator component includes a light wire 21 provided in each branch of the bottom surface of the strip groove 9, and a number of light beads 22 connected in parallel on the light wire 21. Each branch of the strip groove 9 is provided with a switch 23 that is electrically connected to the corresponding light wire 21. In actual use, a power module can be set on the outside of the eyeball assembly, and a control board and a small storage battery can be installed to power the light beads 22. When in use, all the light beads 22 are turned on first. When it is necessary to simulate the blockage or poor flow of a retinal blood vessel 10, the corresponding switch 23 is used to turn off this light wire 21. The retinal blood vessels 10 are all made of light-transmitting material, thus forming a dark area, which allows students to quickly and intuitively understand the lesion phenomenon.

[0034] Combined with appendix Figure 1 , 2 3. The front of hemisphere 1 and hemisphere 2 is detachably provided with a front end assembly, which includes a lens 12 and a corneal portion 13. A connection structure is provided between the front end assembly and hemisphere 1 and hemisphere 2.

[0035] Specifically, the connecting structure includes a semi-circular groove 14 on the front of both hemisphere 1 4 and hemisphere 2 5, a groove 2 15 inside the groove 1 14, and a groove 3 16 inside the groove 2 15.

[0036] Based on the above structure, an annular limiting shoulder 17 is formed between the circular groove 3 16 and the circular groove 2 15, and an annular limiting shoulder 2 18 is formed between the circular groove 2 15 and the circular groove 14; both limiting shoulder 2 18 and limiting shoulder 17 are provided with symmetrical arc-shaped magnetic plates 19 on their front sides, and the lens 12 and the corneal part 13 are provided with magnetic plates 20 on their back sides that can be magnetically attracted to magnetic plates 19; thus, the lens and the corneal part are magnetically connected, and can be removed separately for targeted marking and explanation of lesions in the area. Compared with the fixed model, the detachable type allows important individual components to be removed, making them more conspicuous and easier to observe, and improving the flexibility of use.

[0037] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
