Abstract
A backlight illumination device for digital slit-lamp microscope comprises a slit-lamp microscope, a backlight conductor, a condensing mirror fitted at one side of the backlight conductor and connected to the top of the slit-lamp microscope, a focusing mirror fitted at the one side of the backlight conductor and used for focusing to a reflector, and an optical fiber connected between the two mirrors. Light from the top of a slit lamp is directed to the reflector where it is reflected to the eye of a patient. The utility model can guide lights of slit lamp partially to patient eyes to provide background illumination of coaxial light from the same light source. After equipped with the utility model, slit-lamp microscope can be used for the observation of peripheral tissues in a section of eye without increasing light source, thereby improving the workability of slit-lamp microscope.
Description
Technical field

Background technology
Slit lamp microscope is the common instrument of ophthalmologic examination, and slit lamp microscope mainly is made up of micro-arm 21 and the crack arm 23 be located on the base 20.Micro-arm 21 vertical pivots are enclosed within on the axle of being located at base 20, and arm 23 vertical pivots in crack are enclosed within on the micro-arm 21, and therefore micro-arm 21 can rotate by the axle on base 20, and crack arm 23 can rotate around micro-arm 21 again.The microscope 22 that the doctor is used to observe is located at micro-arm 21, crack light beam focus illumination device is located in the crack arm 23, this device comprise crack arm 23 upper ends slit lamp bulb 17, be located at the crack light beam focusing in the crack arm 23 and be located at 45 ° of reflecting mirrors 18 at crack arm middle part, referring to Fig. 1.The slit lamp light source shines eye by crack light beam focusing and reflecting mirror 18 back light beams with narrow strip " layering ", thereby can clearly show " section " of ophthalmic different tissues, thereby make the doctor clearly observe the pathological changes situation of patient eye inner tissue and to make diagnosis according to this by microscope.But because the slit lamp light source is narrow strip irradiation eyeball after by the crack, the state of the perienchyma in the slit of illumination range of exposures can't not distinguished owing to the illumination deficiency, particularly the image of perienchyma is fuzzy grey black state when taking pictures or make a video recording, and is difficult to provide more diagnostic message.
Summary of the invention
The purpose of this utility model provides a kind of ambient light illumination device of digital slit lamp microscope, can make slit lamp microscope in certain " section " of observing eye, also can observe the situation of the tissue of " section " periphery, thereby promote the function of use of slit lamp microscope.
The ambient light illumination device of a kind of digital slit lamp microscope of the present utility model, mainly comprise a slit lamp microscope, wherein the crack lighting mechanism comprises the slit lamp bulb 17 of being located at crack arm 23 upper ends, is located at the crack light beam focusing in the arm of crack and is located at 45 ° of reflecting mirrors 18 at arm middle part, crack, it is characterized in that bias light light conductor 27 in addition, one end of this light conductor is the optically focused camera lens, link to each other with arm top, crack, the other end is an amasthenic lens, focus on reflecting mirror 18, be connected by optical fiber between the camera lens of two ends.This bias light light conductor 27 causes reflecting mirror 18 with the vertical light source of crack arm 23, and shines patient's eyeball by this reflecting mirror.
The beneficial effects of the utility model are: this device can be guided part slit lamp light source into the patient eye, realizes eye is carried out with the co-axial background illumination of light source.Add on the slit lamp microscope load onto this device after, can be in certain " section " of observing eye, need not to increase light source, just can clearly observe the situation of the tissue of crack " section " periphery, particularly when taking pictures or make a video recording, can when clearly showing the crack image, show the image of perienchyma, for diagnosis provides more information, make slit lamp microscope in ophthalmic diagnosis, bring into play bigger effect, thereby promoted the function of use of slit lamp microscope.

Embodiment
Now the utility model is described in further detail in conjunction with an embodiment and accompanying drawing.
By Fig. 1, the ambient light illumination device of digital slit lamp microscope of the present utility model is to add a light conductor 27 on common slit lamp microscope, by this light conductor with crack arm 23 vertical part light source-guides to reflecting mirror 18 light as a setting, and irradiation patient's eyeball.
By Fig. 1, Fig. 2, an end of described bias light light conductor 27 is the optically focused camera lens, links to each other with the top of crack arm 23, and the other end is an amasthenic lens, focuses on reflecting mirror 18, is connected by optical fiber 3 between the camera lens of two ends.
Described optically focused camera lens is made up of with adjusting ring 10 optically focused microscope base 6, condenser lens 1, grating 2, is fixed on the light source cover 15 of slit lamp light source; Described amasthenic lens is formed by focusing on microscope base 14 and focus lamp 4, is located in the focusing microscope base 5 that is fixed on the middle spreader 16 of crack seat, and focus lamp 4 focuses on the reflecting mirror 18 of being located at arm middle part, crack, again the illuminated eye tissue.Because the same 45 ° of reflecting mirrors 18 of ambient light illumination and crack illumination employing, reflection ray is on coaxial position, so ambient light illumination and the crack same light source, coaxial that throws light on.
By Fig. 3, be fixed on the optically focused microscope base 6 on the vertical light source cover 15 of crack arm 23 and have light hole 7, one side of light hole 7 is equipped with condenser lens 1, be embedded in the hole 7 opposite side, between condenser lens 1 and optical fiber 3, establish a lenticular lenses 2, one adjusting ring 10 is set on the optically focused microscope base 6, and lenticular lenses 2 can be made eccentric swing with adjusting ring 10, thereby regulates luminous flux.
