The following exemplifies how the viewing-sheet assembly frame 21 and the lens assembly frame 22 are implemented to rotate on the simulated fundus component 10.
In some embodiments, as shown in fig. 1 and 2, the simulated fundus component 10 may include a simulated fundus 11 and an eye shell 12; the simulated fundus 11 is fixedly arranged in the eyeball shell 12, the viewing-piece assembling frame 21 is rotatably arranged in the eyeball shell 12 around a first axis P1, for example, a rotating shaft hole can be arranged on the eyeball shell 12, a bulge 21b is formed on the viewing-piece assembling frame 21, the bulge 21b is arranged in the rotating shaft hole, and the axis of the rotating shaft hole can be used as a first axis P1; the lens frame 22 is rotatably provided on the eyeball housing 12 about a second axis P2, and for example, a rotary shaft (not shown) whose axis is the second axis P2 is provided on the simulated fundus 11, and the lens frame 22 is rotatably connected to the rotary shaft. The lens assembly frame 22 and the eyeball housing 12 may also rotate in a clamping manner, that is, an annular clamping groove is formed in the circumferential direction of the opening of the eyeball housing 12, a clamping protrusion corresponding to the annular clamping groove is formed on the lens assembly frame 22, and the clamping protrusion is clamped into the annular clamping groove. It is to be understood that the simulated fundus 11 in the present embodiment may be fixedly provided in the eyeball housing 12 in a structure in which the simulated fundus 11 is integrally formed with the eyeball housing 12 or the simulated fundus 11 may be detachably fixed in the eyeball housing 12.
In order to make the eye teaching aid more vivid, the eyeball housing 12 and the lens assembly frame 22 are buckled together to form a sphere, and the outer surface of the lens assembly frame 22 may be a spherical structure.
Preferably, the first axis P1 and the second axis P2 are axisymmetrically arranged with respect to the axis P3 of the simulated retina 30, so that the viewing plate assembly frame 21 and the lens assembly frame 22 can rotate 360 °, more simulated refraction interstitial viewing plates 21a can be arranged on the viewing plate assembly frame 21, more lenses 22a are arranged on the lens assembly frame 22, so as to simulate eye diseases with more symptoms, and simulate traces generated by laser irradiation on the simulated retina 30 under different symptoms, so as to facilitate understanding of laser irradiation parameters under different disease conditions. Of course, the first axis P1 and the second axis P2 may be vertical, as shown in fig. 3, in this case, the viewing-sheet assembling frame 21 may be rotatably disposed on the simulated fundus 11 by the first rotating shaft 24, the axis of the first rotating shaft 24 is taken as the first axis P1, the lens assembling frame 22 may be rotatably disposed on the simulated fundus 11 by the second rotating shaft 25, the axis of the second rotating shaft 25 is taken as the second axis P2, the first rotating shaft 24 and the second rotating shaft 25 may intersect with the axis P3 of the simulated retina 30, the viewing-sheet assembling frame 21 and the lens assembling frame 22 may be disposed on the opposite side of the simulated retina 30, compared with the structure in which the first axis P1 and the second axis P2 are axisymmetrically disposed with respect to the axis P3 of the simulated retina 30, the viewing-sheet assembling frame 21 and the lens assembling frame 22 may only realize a certain angle rotation and a 360 degree rotation, that is, that a number of simulated refractive viewing discs 21a large number cannot be disposed on the viewing-sheet assembling frame 21, and a larger number of lenses 22a cannot be provided on the lens assembly frame 22, the number of simulatable diseases is relatively small, and compared with the prior art, the function of simulation teaching is also basically realized.

Compared with the implementation mode, the structure is simple, but only one group of simulated refraction interstitial vision film 21a and lens 22a is arranged in each pupil, the combination mode is single, the symptoms of the simulated eye diseases are less, and the function of the simulated teaching is basically realized.
In some embodiments, the plurality of simulated refractive interstitial vision discs 21a may be lenses with different opacities, and are combined with different lenses 22a, and laser light passes through the lenses 22a and the simulated refractive interstitial vision discs 21a in sequence and is converged to form different spots on the simulated retina through laser irradiation, so that a student can know the change of the retina when laser light is used for treatment under different pathological conditions.
In some embodiments, the diameters of the multiple pupils are of different sizes, and lenses 22a of different diameters may be embedded.
In some embodiments, the viewing lens assembly frame 21 and/or the lens assembly frame 22 are removably coupled to the simulated fundus 11, and the simulated retina 30 is removably coupled to the simulated fundus 11, facilitating viewing and replacement of the simulated retina 30.
In some embodiments, the surface of the light incident side of each lens 22a is a smooth convex surface, the surface of the light emergent side of each lens 22a is a smooth concave surface, the curvatures of the convex surfaces of the plurality of lenses 22a can be different or the same, and the lenses can be reasonably matched according to the diameters of different pupils and combined with the simulated refractive interstitial vision discs 21a with different turbidities to simulate eye diseases with different symptoms.
