Description
Technical field
This utility model relates to ophthalmic medical instrument field, is specifically related to a kind of slit lamp microscope with filter disc rotating function.
Background technology
Slit lamp microscope claims again " finishing tool ", for light is seen through to an ophthalmic medical instrument throwing light on to eyes in crack, slit lamp microscope forms an optical section by irradiating in eyes, be the health status at the each position of observable eyes, its principle is " Tyndall phenomenon " of having utilized English physicist dindar.The ophthalmologist Gullstrand of Sweden in 1911 has invented famous ophthalmology checking Instrument " slit lamp microscope " (Slit lamp), and nineteen twenty vogt is improved makes its function more perfect, becomes the slit lamp microscope source of today.Along with the fast development of computer technology, digital image-forming technology, novel photographing slit lamp microscope style constantly updated in recent years.Wherein the application of digital camera is extremely praised highly.Picture report can be printed on same report with textual diagnosis, and audit report can accomplish to look into.So far photo slit lamp microscope has just entered actual clinical practice.
Common slit lamp microscope comprises with slit lamp and microscopical workbench at present.For the ease of slit source, from the 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.Its edge, crack of the light source requirements of slit lamp microscope must be very smooth, and crack must be imaged on the center of circle vertical swinging 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 microscope must be installed on relatively dark indoor of light, and slit source is illuminated to eyes, then checks that doctor is by the health status at the each position of microscopic examination eyes.In the filter disc of illumination path, also place the optical filter of different wave length, can, according to the needs of various inspections, send the slit of illumination of various different colours, made the observation under certain situation more clear.Blue filter disc is usually used in Fluirescence observation, and green filter disc is for observing blood vessel.As in the time 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 vitreous body 1/3 by slit lamp microscope 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 microscope be not only ophthalmologist check visual plant, also become join mirror optometry personnel indispensability and must grasp instrument.The microscopical filter disc of existing slit lamp microscope, is by the manual filter disc that directly rotates, and realizes the exchange of different optical filters, the optical filter negligible amounts of installation, and its rotational angle only has 180 degree.In doctor's checking process, in the time of needs repeated observation, can only repeatedly rotate filter disc, encounter and need to use in the time rotating the optical filter at end points place for two, the angle of repeatedly rotating reaches 180 degree.This structure and mode of operation have been brought very big inconvenience to doctor, first ophthalmologic examination require highly, and patient should not carry out examination for a long time, as meets child, because of its active nature with fear doctor's psychology, is difficult to concentrate on accepting long-time inspection; Second doctor, darker indoor, rotates filter disc light modulation repeatedly, and the improper energy that consumes doctor also easily causes checking the error of judgement.
Utility model content
The technical problems to be solved in the utility model is to provide one can realize the rotation continuously of filter disc 360 degree, thereby effectively saves the slit lamp microscope with filter disc rotating function of doctor's review time, raising checking efficiency and accuracy.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of slit lamp microscope with filter disc rotating function, comprise with slit lamp and microscopical workbench, the top of described workbench is provided with the filter disc that axis is arranged along vertical direction, one side of described workbench is arranged with rotating knob, the axis of described knob is arranged along horizontal direction, the edge of described filter disc is provided with multiple for the optical filtering hole of optical filter is installed, the middle part of described filter disc is provided with connection copper sheathing, the lower end of described connection copper sheathing is connected with driven wheel of differential, the end of described knob is provided with drive bevel gear, described drive bevel gear, intermeshing between driven wheel of differential.
The sheathed positioning mark dish that is fixed with on described knob.
The edge of described positioning mark dish is provided with and the hole multiple index points one to one that filter.
The slit lamp microscope that the utlity model has filter disc rotating function has following advantage: a side of this utility model workbench is arranged with rotating knob, the axis of knob is arranged along horizontal direction, the edge of filter disc is provided with multiple for the optical filtering hole of optical filter is installed, the middle part of filter disc is provided with connection copper sheathing, the lower end that connects copper sheathing is connected with driven wheel of differential, the end of knob is provided with drive bevel gear, drive bevel gear, intermeshing between driven wheel of differential, turning knob can drive drive bevel gear to rotate, due to drive bevel gear, intermeshing between driven wheel of differential, therefore drive bevel gear is converted to knob to connect the rotation of copper sheathing along vertical direction by driven wheel of differential along the rotation of horizontal direction, thereby drive filter disc to rotate, can realize filter disc 360 degree rotates continuously, thereby effectively save doctor's review time, improve checking efficiency and accuracy, and shorten patient's light application time, reduce medical-risk, also improved the medical environment of child and weak colony.
