Embodiment 1

[0048] Such as Figure 2-6 As shown in the figure, a kind of eye model for simulating cataract operation includes chassis 26, dry experimental eye model, upper and lower funnel 28, first simulated cornea 30 and bottom cover 29; also includes top cover 31, so The top cover 31 is buckled on the chassis 26 , and the top cover 31 is provided with a through opening 32 , and the opening 32 can leak out of the funnel 28 . The top cover 31 can achieve the effect of simulating a human face.

[0049] The chassis 26 is provided with the dry test eye model and the funnel 28, and the dry test eye model is spaced apart from the funnel 28;

[0050] The bottom end of the funnel 28 is threadedly connected with the bottom cover 29, and the top of the funnel 28 is sealed by the first simulated cornea 30, and a pig's eye is housed in the funnel 28; through holes.

[0051] Specifically, the dry experimental eye model includes a cylindrical bottom member 1 with a small top and a large bottom, a ...

Embodiment 2

[0060] Such as Figure 7 As shown, the difference from Embodiment 1 is that the locking device 14 includes a base 21, a handle 24, a first fixed block 15 and a telescopic spring 19, and the bottom surface of the base 21 is fixedly connected to the side of the bottom member 1. ;

[0061] A second fixed block 17 is fixed on the top surface of the base 21, and the second fixed block 17 is hinged to one end of the connecting shaft 20 through a pin shaft 18, and the connecting shaft 20 is away from one end of the second fixed block 17 It is fixedly connected with one end of the telescopic spring 19, and the other end of the telescopic spring 19 is connected with the first fixed block 15;

[0062] The side wall of the base 21 is connected with the side wall of the third fixed block 25, the third fixed block 25 is movably connected with the bottom surface of the handle 24, and one end of the handle 24 is connected with the first fixed block 15 And the handle 24 is on the same level...

Embodiment 3

[0066] The difference between Embodiment 3 and Embodiment 1 is that the inner wall of the base member 1 is provided with a ring-shaped protrusion 22, and the first simulated lens 6 can extend into the inner ring of the protrusion 22 and is compatible with the inner wall of the protrusion 22. The side walls of the protrusions 22 abut against each other.

[0067] A specific embodiment is that the horizontal displacement of the first simulated lens 6 can be prevented by the protrusion 22 . Ensure the normal progress of cataract simulation surgery.

Abstract

The invention belongs to the field of medical equipment, and particularly relates to an eye model for simulating cataract surgery. The eye model includes a bottom plate, a dry experimental eye model,a big-end-up funnel, a first simulated cornea and a bottom cover, the bottom plate is provided with the dry experimental eye model and the funnel, and the dry experimental eye model and the funnel arearranged in a spaced mode; the bottom end of the funnel is connected with the bottom cover in a threaded mode, the top end of the funnel is sealed by the first simulated cornea, and the funnel is internally provided with a pig eye; and the bottom cover is provided with a plurality of through holes. According to the eye model for simulating the cataract surgery, when simulating the cataract surgery, the dry eye model can be used for dry experiments, the funnel can also be used for wet experiments, the actual cataract surgical procedure is well simulated, the good condition for improvement andconnection of surgical skills of doctors is provided, and the success rate of the cataract surgery is indirectly increased.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to an eye model for simulating cataract surgery. Background technique [0002] Cataract is a common blinding eye disease. There is a tissue in the human eye called the lens. Under normal circumstances, it is transparent. Light passes through it and some refractive media to reach the retina, so that external objects can be seen clearly. Once the lens is clouded for some reason, it will affect the imaging of the retina and make people unable to see clearly. In other words, clouding of the lens leading to decreased vision is a cataract. Early clouding does not affect vision when it is slight or in a small range, and then gradually aggravates to significantly affect vision or even blindness. Vision loss caused by cataracts cannot be corrected with eyewear. [0003] At present, cataract surgery is a common method for treating cataract. Since the surgical site of cataract surgery is t...
