Technical field
The present invention relates to a kind of ophthalmologic examination slit lamp microscope, particularly relate to a kind of rotating mechanism of light source slit lamp microscope filter disc down.
Background technology
Slit lamp is as the term suggests be exactly that light throws light on to eyes through a crack.Owing to be a narrow slit light source, therefore be referred to as by " finishing tool ".This " finishing tool " shone in optical section of eyes formation, the health status that can observe each position of eyes.Its principle is " Tyndall phenomenon " of having utilized Britain's physicist dindar.Tyndall phenomenon is: when Ray Of Light sees through colloid, can observe " path " of a light that occurs in the colloid from the vertical direction of incident illumination, this phenomenon also is Tyndall effect Tyndall phenomenon.The ophthalmologist Gullstrand of Sweden in 1911 has invented famous ophthalmology checking Instrument " slit lamp " (Slit lamp), and nineteen twenty vogt is improved makes its more perfect function, becomes the slit lamp source of today.Along with the fast development of computer technology, digital image-forming technology, novel photographing slit lamp style constantly updated in recent years.Wherein the application of digital camera is extremely praised highly.The picture report can be printed on same the report with textual diagnosis, and audit report can accomplish promptly to look into promptly.So far photoslit-lamp has just entered actual clinical practice.
The structure of slit lamp mainly is made of two parts, i.e. " slit lamp " and " microscope ".From different each positions of angular illumination eyes, and microscope observes eyes from different angle, requires slit lamp and microscope mechanically all to have enough angles that swings for the ease of slit source.Its edge, crack of the light source requirements of slit lamp must be very smooth, and the crack must be imaged on the center of circle vertical that swings clearly, and microscopical focusing equally also must focus on this center of circle vertical.
In order effectively to observe the health status of eyes, slit lamp must be installed on darker relatively indoor of light, and slit source is illuminated eyes, then checks the health status of doctor by each position of microscopic examination eyes.In the filter disc of illumination path, also placed the optical filter of different wave length, can send the slit of illumination of various different colours, made the observation under certain situation more clear according to the needs of various inspections.Blue filter disc is usually used in Fluirescence observation, and green filter disc then is used to observe blood vessel.As when carrying out fluoroscopy, just send the coloured light of fluorescence excitation element.Can clearly observe before eyelid, conjunctiva, sclera, cornea, anterior chamber, iris, pupil, crystalline lens and the vitreous body 1/3 by slit lamp microscope, can determine position, character, size and the degree of depth thereof of pathological changes.If be equipped with adnexa, its examination scope will be more extensive.Thereby slit lamp is not only the visual plant that the ophthalmologist checks, also becomes indispensability of joining mirror optometry personnel and the instrument that must grasp.
The filter disc of existing slit lamp microscope is by the manual filter disc that directly rotates, and realizes the transposing of different optical filters, and the optical filter negligible amounts of installation, its rotational angle have only 180 degree.In doctor's checking process, when the needs repeated observation, can only rotate filter disc repeatedly, running into needs to use when rotating the optical filter at end points place for two, and the angle of Zhuan Donging promptly reaches 180 degree repeatedly.This structure and mode of operation have been brought very big inconvenience to the doctor, and the requirement height of ophthalmologic examination, and patient first should not carry out examination for a long time, as meets the child, because of its active nature and the psychology of fearing the doctor, are difficult to concentrate on accepting long-time inspection; Second the doctor rotates the filter disc light modulation repeatedly darker indoor, and the improper energy that consumes the doctor also easily causes checking the error of judgement.
Summary of the invention
For solving the deficiency of existing slit lamp microscope filter disc operation, the purpose of this invention is to provide the filter disc that a kind of energy 360 degree rotate continuously, increased detection range, thereby effectively saved doctor's review time, improved checking efficiency and accuracy.
The present invention solves the problems referred to above that prior art exists, the technical scheme that adopts is: a kind of light source slit lamp microscope filter disc rotating mechanism down, comprise illumination work platform, filter disc, turning cylinder, it is characterized in that: below filter disc with turning cylinder joint portion socket one annular gear wheel, below illumination work platform platform, establish one 360 degree rotation hand wheels, a connecting axle is established at the handwheel center, connecting axle passes illumination work platform platform, one 360 degree swing pinions, 360 degree swing pinion and annular gear wheel engagement in rotation are established in its upper end.
The operator drives the rotation of 360 degree swing pinions by revolving the three-sixth turn rotation hand wheel, and the rotation of 360 degree swing pinions drives the rotation of annular gear wheel again, and filter disc is moving thereupon, thereby realizes the continuous rotation transposing of filter disc optical filter 360 degree.
The invention has the beneficial effects as follows: can not equidirectional continuous rotation compare with existing slit lamp microscope filter disc, filter disc of the present invention rotates by gear driven, realized the equidirectional continuous rotation of 360 degree, the doctor is darker indoor, carry out in the checking process, when the needs repeated observation, can pass through the continuous rotating filtering dish of rotation hand wheel, thus the review time of effectively having saved the doctor.Existing slit lamp microscope is limited to the filter disc rotational angle, generally can only establish 3 to 5 optical filtering holes, as the more optical filter of needs, can only replace mounted, causes the very big inconvenience of inspection.And filter disc of the present invention because of can 360 the equidirectional continuous rotation of degree, so can be provided with, make the doctor that more point of observation arranged than the existing slit lamp microscope hole of more filtering.Therefore, the present invention has improved checking efficiency and accuracy, and has shortened patient's light application time, has reduced medical-risk; Also improved the medical environment of child and weak colony.
