Teaching appliance capable of assisting in memorizing extraocular muscle function

Abstract

The invention discloses a teaching aid capable of assisting in memorizing extraocular muscle functions, which comprises rotatable left and right eyeball model components, left and right hand model components, spherical left and right eyeball models, corresponding extraocular muscle patterns printed on corresponding parts on the surfaces of the left and right eyeball models, the left and right eyeball models are movably mounted in mounting components, and the left and right eyeball models are movably mounted in the mounting components. The mounting part is of a hollow or transparent structure, the upper parts of the left eyeball model and the right eyeball model are exposed, and the left eyeball model and the right eyeball model can rotate under the manual action; the left-hand model and the right-hand model are in the state that the index finger, the middle finger and the thumb are opened and the ring finger and the little finger are closed, and the left-hand model and the right-hand model have front and back surfaces, can be mutually independent and can be taken up or put down. The teaching aid can assist in teaching and improve learning and memorizing efficiency, can quickly judge the corresponding extraocular muscle function through the visual eyeball model capable of being operated by hands and the use of the left and right hand model, and has the characteristics of intuition, operability and pithy formula teaching.

Description

technical field [0001] The invention relates to the field of teaching utensils and teaching aids, mainly relates to the field of teaching equipment for ophthalmic anatomy knowledge, in particular to a teaching utensil capable of assisting memory of extraocular muscle functions. Background technique [0002] The extraocular muscle is the striated muscle responsible for eye movement. There are 6 muscles in each eye. According to their running direction, they are divided into rectus and oblique muscles. The 4 rectus muscles are upper, lower, inner and outer rectus muscles. muscle and inferior oblique. All four rectus muscles originate from the common tendon ring around the optic foramen at the orbital apex. The muscle fibers of each muscle form a bundle, which surrounds the optic nerve and spreads forward from the upper, lower, inner and outer directions and crosses the equator of the eyeball, respectively, and attaches to the sclera at different distances from the corneal lim...

AI Technical Summary

Problems solved by technology

[0003] In the process of diagnosis of eye movement diseases, it is possible to preliminarily determine which muscles have pathological problems through eye movement disorders. In middle school, it is difficult for students to quickly and accurately remember the function of extraocular muscles and quickly make a judgment on the dysfunction of extraocular muscles. , is a relatively difficult part of ophthalmology professional teaching
