Description
Technical field
The utility model relates to a kind of ophthalmology department teaching model, particularly a kind of electric model of simulating eyeball and EOM.
Background technology
In the eye socket of eyeball type of being positioned at rectangular pyramid type, the madial wall of eye socket is parallel to each other, and the summit of rectangular pyramid is that the obital apex of eye socket points to fossa cranii media.The motion of each eyeball is all produced by or the anti-motion of knot collaborative attached to extrabulbar six muscle, and wherein inside and outside four rectus play the fibrous ring from obital apex up and down, terminate in the inside and outside wall up and down of eyeball.Musculus obliquus dorsalis rises from the obital apex fibrous ring, and the coaster of walking around top in the socket of the eye arm terminates in the outer back upper place of eyeball, and inferior oblique muscle rises from the socket of the eye lower inner wall, terminates in the outer back lower place of eyeball.Internal rectus muscle can make in the eyeball level to be changeed, and musculus rectus lateralis can make the eyeball level change outward.Superior rectus, inferior rectus muscle, musculus obliquus dorsalis and inferior oblique muscle can produce a main action and one to two less important action, and superior rectus can make on the eyeball to be changeed, interior commentaries on classics, inward turning (cornea vertical meridian upper limb rotates to nasal side); Inferior rectus muscle can make subduction, interior commentaries on classics and outward turning (cornea vertical meridian upper limb is to the temporo sideway swivel); Musculus obliquus dorsalis can make the eyeball inward turning, following commentaries on classics and outer the commentaries on classics; Inferior oblique muscle can make eyeball screw on outward to be changeed and outer the commentaries on classics.
The method that is used for auxiliary EOM teaching at present has graphic interpretation and modelling.Graphic interpretation is to describe the relation of eyeball between extraocular muscle with the internal anatomy of eye socket, interlocks in length and breadth because extraocular muscle and eyeball are spatial structure, particularly extraocular muscle in eye socket, and the internal anatomy on plane is difficult to accomplish clear description intuitively.In eyeball phantom, commonly used now has two kinds: a kind of is traditional eyeball anatomical model, mainly describes the inner structure of eyeball, and extraocular muscle has only been described their stops, does not relate to structure and the traveling of extraocular muscle in eye socket, is not easy to students understand.Another kind of novel eyeball anatomical model has been opened the lateral wall of eye socket; Stop and the traveling of extraocular muscle in eye socket described; But because model is static; Shortage to when motion eyeball and extraocular muscle between the description that concerns, and this just relation has caused the different eyes position under physiology and the pathologic condition, so this static model still can not let the origin cause of formation of this kinematic relation of students understand and various pathology eyes position intuitively.Therefore; The teaching of extraocular muscle is puzzlement person's ophthalmology department teaching worker for a long time; The student seldom can understand extraocular muscle relation each other through teaching in short-term, has caused puzzlement for classmates, and the extraocular muscle model of a motion of development is ophthalmology worker's a wish always.
In 1996; An American students group that is called " Leonardo da Vinci group " has made first extraocular muscle model in the world; Simulated extraocular muscle out of shape around eyeball with nylon wire, its feature is the counterweight that an indication weight is arranged on the nylon wire of every simulate muscular, can show the power that nylon rope is suffered; But it can not make real the rotating of eyeball.
Summary of the invention
