A detachable ophthalmic corneal foreign body removal model

Abstract

The invention relates to the field of medical education human models, in particular to a detachable ophthalmic corneal foreign body removing model. The basic structure of the model comprises a cornea, a conjunctiva, a sclera, a rotating eyeball, an eye ground part and a fixed device, wherein the cornea, the conjunctiva and the sclera are arranged in the front, the rotating eyeball is arranged in the middle, and the eye ground part and the fixed device are arranged at the back. Foreign bodies exist on the cornea, the cornea is connected with the conjunctiva, the conjunctiva is directly arranged on the sclera in a sleeving mode, the rotating eyeball is arranged inside the sclera, the eye ground part is connected to the back of the rotating eyeball and used for fixing the rotating eyeball, the eye ground part is connected with the fixed device, the fixed device is fixed on a face model, and the face model comprises skin surrounding the eye and a human head model. The detachable ophthalmic corneal foreign body removing model is high in simulation and precision, foreign bodies simulate clinical real situations, practical operability is high, and consumables can be detached and replaced repeatedly through rubidium magnet attracting connection.

Description

technical field [0001] The invention relates to the field of medical education mannequins, in particular to a detachable ophthalmic corneal foreign body removal model. Background technique [0002] The eye is small in size and complex in structure. Traditional ophthalmology teaching aids are magnified models of eye structures and functional models in optometry. These teaching aids are often made of hard plastic, which can only be observed but not operated. In addition, due to the large volume and low accuracy requirements of traditional surgical operation teaching aids, it can be realized by the "mold opening-injection molding" method. This method cannot produce teaching aids with complex structures and small volumes, such as eye models. [0003] Corneal foreign body refers to an ophthalmic emergency caused by dust, small insects, metal fragments, wood chips and other foreign bodies accidentally entering the cornea of ​​the eye. Since the cornea is located on the surface o...

AI Technical Summary

Problems solved by technology

The problems exposed by these methods are as follows: 1. Students have strong theoretical knowledge, weak practical ability, and few opportunities for clinical hands-on practice; 2. There are anatomical differences between animal eyes and human eyes, so the simulation effect is general

Therefore, there is still a lack of an ophthalmic corneal foreign body removal model to assist students or young doctors with low qualifications to train ophthalmological corneal foreign body removal practical skills.
