In some embodiments of the present invention, as shown in fig. 1-3, the adjustment assembly 20 may include a view block assembly 21 and a lens assembly 22; wherein, the vision film assembly frame 21 is rotatably arranged on the simulated fundus assembly 10 around the first axis P1, the vision film assembly frame 21 is circumferentially provided with a plurality of mounting holes along the first axis P1 at intervals, and each mounting hole is provided with a simulated refraction interstitial vision film 21a; the lens assembly frame 22 is rotatably arranged on the simulated fundus assembly 10 around the second axis P2, a plurality of simulated pupils are arranged on the lens assembly frame 22 along the circumferential direction of the second axis P2 at intervals, and each simulated pupil is provided with a lens 22a; when the lens assembly frame 21 and the lens assembly frame 22 are rotated, any one of the plurality of simulated refractive stromal lenses 21a and any one of the plurality of lenses 22a can be moved to the side opposite the simulated retina 30.
The lens assembly frame 21 and the lens assembly frame 22 may have a bowl-shaped structure, and a part of the lens assembly frame 21 is located in the lens assembly frame 22, so that when the lens assembly frame 21 and the lens assembly frame 22 rotate, one of the above-mentioned simulated pupils is opposite to one of the above-mentioned simulated refractive interstitial lenses 21a, and the simulated refractive interstitial lenses 21a opposite to the lenses are opposite to the simulated retina 30, so that when the laser passes through the lenses 22a of the simulated pupils, the laser passes through the simulated refractive interstitial lenses 21a and irradiates the simulated retina 30 to form marks, and when the eye diseases simulating different symptoms are combined and matched with different combinations of the simulated refractive interstitial lenses 21a and the lenses 22a, the influence on the retina during laser irradiation under different symptoms is conveniently known, the influence of the laser irradiation in the actual operation process is conveniently known, and the risk caused by directly performing operation on the patient without experience is avoided.
The following exemplifies how the lens assembly frame 21 and the lens assembly frame 22 are implemented to rotate on the simulated fundus assembly 10.
In some embodiments, as shown in fig. 1 and 2, a simulated fundus assembly 10 may include a simulated fundus 11 and an ocular housing 12; the simulated fundus 11 is fixedly arranged in the eyeball casing 12, the video assembly frame 21 is rotatably arranged in the eyeball casing 12 around a first axis P1, for example, a rotating shaft hole can be arranged on the eyeball casing 12, a bulge 21b is formed on the video assembly frame 21, the bulge 21b is arranged in the rotating shaft hole, and the axis of the rotating shaft hole can be used as the first axis P1; the lens assembly frame 22 is rotatably provided on the eyeball housing 12 about a second axis P2, and for example, a rotation shaft (not shown in the drawing) may be provided on the simulated fundus 11, with the axis of the rotation shaft serving as the second axis P2, and the lens assembly frame 22 is rotatably connected to the rotation shaft. The lens assembly frame 22 and the eyeball casing 12 may rotate in a clamping manner, that is, an annular clamping groove is formed in the circumferential direction of the opening of the eyeball casing 12, and a clamping protrusion opposite to the annular clamping groove is formed on the lens assembly frame 22 and clamped into the annular clamping groove. It is to be understood that the simulated fundus 11 in the present embodiment may be fixedly disposed in the eyeball housing 12 in a structure in which the simulated fundus 11 is integrally formed with the eyeball housing 12 or in which the simulated fundus 11 is detachably fixed in the eyeball housing 12.
In order to make the eye teaching aid more visual, the eyeball casing 12 and the lens assembly frame 22 are buckled together to form a sphere, and the outer surface of the lens assembly frame 22 can be in a spherical structure.
Preferably, the first axis P1 and the second axis P2 are axially symmetrically arranged relative to the axis P3 of the simulated retina 30, so that 360-degree rotation of the vision lens assembly frame 21 and the lens assembly frame 22 can be realized, more simulated refractive interstitial vision lenses 21a can be arranged on the vision lens assembly frame 21, more lenses 22a are arranged on the lens assembly frame 22, eye diseases with more symptoms are simulated, and marks generated by laser irradiation to the simulated retina 30 under different symptoms are simulated, so that laser irradiation parameters under different conditions of a needle can be conveniently known.

The structure is simple compared with the implementation mode, but only one group of simulated refraction interstitial vision films 21a and lenses 22a can be arranged in each pupil, the combination mode is single, the symptoms of the simulated eye diseases are fewer, and the function of simulated teaching is basically realized.
In some embodiments, the multiple simulated refractive stromal discs 21a may be lenses with different turbidity degrees, and combined with different lenses 22a, and through laser irradiation, laser sequentially passes through the lenses 22a, the simulated refractive stromal discs 21a and converges to spots on the simulated retina to form different marks, so that a learner can know the change of the retina when using laser treatment under different pathological conditions.
In some embodiments, the diameters of the pupils are different in size, and lenses 22a of different diameters may be embedded.
In some embodiments, the optic assembly mount 21 and/or the lens assembly mount 22 are removably connected to the simulated fundus 11, and the simulated retina 30 is removably connected to the simulated fundus 11, facilitating viewing and replacement of the simulated retina 30.
In some embodiments, the surface of each lens 22a on the light incident side is a smooth convex surface, the surface on the light emergent side 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 lens 22a can be reasonably matched according to the diameters of different pupils and combined with the simulated refractive interstitial vision films 21a with different turbidity to simulate eye diseases with different symptoms.
In some embodiments, the simulated fundus 11 is formed with a concave spherical surface on which the simulated retina 30 is disposed.
