Description
Technical field
The invention belongs to medical equipment fields, are specifically related to a kind of for simulating the eye model of cataract operation.
Background technique
Cataract is common blinding eye disease.There is a tissue to be called crystalline lens in human eye, it is under normal circumstances
Bright, light passes through it and some refractive medias reach retina, could can be clearly seen that external object.Once crystalline lens due to
Muddiness, which occurs, for certain reasons just will affect retina image-forming, make one not seeing thing.That is, phacoscotasmus leads to eyesight
Decline is exactly cataract.Early stage muddy slight or range does not affect vision when smaller, is then gradually weighed out to and significantly affects eyesight
Even blind.Visual impairment caused by cataract can not be by wearing eye correction.
Cataract operation is the conventional means for treating cataract at present, since the operative site of cataract operation is eyes,
Once lacking practice Direct Surgery, it is easy to the fault in surgical procedure is caused, to cause the wound that can not be retrieved to patient.
So needing to give the doctor to perform an operation training, simulation operation is usually used this when, for simulating cataract operation
Eye model is main simulation operation chief component.Shown in Fig. 1, eyes include cornea 1, anterior chamber 3, iris 3, crystalline lens
4, vitreum 5, optic nerve 6 and retina 7.Eye model for simulating cataract operation needs reduction measured to the greatest extent true
Cataract eyes need the cornea 1 and crystalline lens 4 operated particularly with operation, even more there is high model needs.Existing skill
In art, the existing eye model fidelity for simulating cataract operation is not high, can not effectively be trained for doctor,
So being difficult the cataract operation model of simulation reality.Cause the cataract operation level of doctor to be promoted slow, is a urgent need solution
Certainly the problem of.
Summary of the invention
For the present invention in order to solve the technical problem in above-mentioned background technique, real human body eye can effectively be simulated by providing one kind
The eye model for being used to simulate cataract operation of ball.
The technical scheme to solve the above technical problems is that a kind of for simulating the eyes mould of cataract operation
Type, including chassis, stemness experiment eye model, up big and down small funnel, the first analog cornea and bottom cover；
The chassis is equipped with stemness experiment eye model and the funnel, the stemness experiment eye model and institute
State Infundibulum septum setting；
The bottom end of the funnel is threadedly coupled with the bottom cover, and the top of the funnel is close by first analog cornea
Envelope, the funnel are provided with pig eye；
The bottom cover is equipped with several through-holes.
The beneficial effects of the present invention are: the present invention both can use stemness experiment eyes when simulating cataract operation
Model carries out stemness experiment, also can use funnel and carries out moist experiment.Since funnel is provided with pig eye, it is possible to simulate white
Cataract surgery.Notch is carried out to the first analog cornea, the pig eye in funnel is operated.The water of pig eye exudation passes through in funnel
Through-hole on bottom cover is discharged on chassis.It ensure that being normally carried out for simulation cataract operation.
Based on the above technical solution, the present invention can also be improved as follows.
Further, stemness experiment eye model include up-small and down-big cylindrical base component, horizontally disposed disk,
