Abstract
A double light route and semi-reflector device of synoptophore is a double light route semi-reflector ophthalmologic medical device used for examination, diagnosis, treatment and training on human strabismus and optical functions, belonging to the photoelectrical medical equipment field. The technical proposal provides a structure with both a semi-reflector and a ring lens base with an added port to improve the total reflector in the prior art. The utility model takes a premaxilla supporter as the center, which is divided into two optic routes including a left one and a right one, each of which comprises a light cell, a film case, a lens tube, a semi-reflection mechanism and an ocular group, wherein the optical axis of both the left and the right optic routes are in the same axial line; the film case, the semi-reflection mechanism and the ocular group are arranged in turn in front of each of the two optic routes along the spreading direction of the light. The reflection mechanism becomes the semi-reflection mechanism to measure the strabismus angle when the port of the lens base is opened, and becomes the whole reflection mechanism to examine the other optical functions when the port is closed. The utility model has a simple operation.
Description
(1) technical field: this utility model belongs to the double light path half reflection mirror ophthalmology medical apparatus of a kind of people's of being used for anorthopia, visual performance inspection, diagnosis, treatment and training in the photoelectricity medical instruments field.
(2) background technology: before this utility model, be used for the double light path reflector apparatus of the synoptophore of people's anorthopia, visual performance inspection, diagnosis, treatment and training usefulness, domestic and international most of producers all adopt the total-reflection type mirror structure.For example: the double-light path full-reflection mirror structure of the 2001 type synoptophores that Britain produces, double-light path full-reflection mirror structure of the TSJ-IV type A synoptophore that the double-light path full-reflection mirror structure of the 1005 type synoptophores that China Huadong Optical Instrument Factory produces and Changchun photoelectric instrument factory produce or the like, the prior art the most approaching with this utility model is the double-light path full-reflection mirror structure of the TSJ-IV type A synoptophore of Changchun photoelectric instrument factory production.As shown in Figure 1: be to be symmetrical centre, be divided into left and right sides two-way by former jaw holder 16.Left side optical routing lamp house (1,2), film magazine (3,4), lens barrel 5, completely reflecting mirror mechanism (6,7) and eyepiece group 17 are formed.Wherein lamp house comprises that light source 1, lamp house 2, film magazine comprise that film magazine 3, visual 4, completely reflecting mirror mechanism comprise completely reflecting mirror 6, total reflection microscope base 7.Right side optical routing lamp house (14,13), film magazine (11,12), tube mirror 10, completely reflecting mirror mechanism (8,9) and eyepiece group 15 are formed.Wherein, lamp house comprises that light source 14, lamp house 13, film magazine comprise that film magazine 12, visual 11, completely reflecting mirror mechanism comprise completely reflecting mirror 9, total reflection microscope base 8.
There is following point in the double-light path full-reflection lens device of this synoptophore: carry out him and feel when the angle of strabismus is checked, the examiner can not directly see the mobile status of those who are investigated's eyeball and the inclination situation of eye position in the optics visual field; Gather with opening and to observe directly those who are investigated's eyeball when loose checking and whether do set and open diffusing same moved further with lens barrel; When carrying out the inspection of conscious angle of strabismus, the examiner can not monitor that whether those who are investigated watch the visual in the lens barrel attentively, directly have influence on the accuracy that conscious angle of strabismus is checked; Prior problem is the double-light path full-reflection lens device of this synoptophore, make those who are investigated when observing visual, eye muscle takes place to be regulated, make the eyes adductor shrink set, can make the esotropia degree bigger than normal, exotropia's degree is less than normal, and the measurement accuracy of angle of strabismus is produced than mistake, bring inaccurately to diagnosis, have a strong impact on treatment effect.Based on the problem of above-mentioned existence, must the double-light path full-reflection illuminating apparatus structure of this synoptophore be improved.Make synoptophore check, diagnose people's anorthopia that more effective effect is brought into play in aspects such as visual performance.
(3) summary of the invention: the technical problem that this utility model solves is to remove that (total reflection mechanism) overcomes the anorthopia to the people to the regulating action of eye muscle, the inspection error of visual performance in the prior art.
