Abstract
The utility model relates to a dual-slit lamp lighting device and particularly relates to an auxiliary lighting device used when a slit lamp microscope is used for examination. The dual-slit lamp lighting device comprises a first focusing mirror assembly which consists of a lamp holder, a first collecting mirror and a lighting light source. The dual-slit lamp lighting device is characterized by further comprising a second focusing mirror assembly which comprises a collecting mirror seat, a second collecting mirror, a manual-control adjusting seat and a rotating pin, wherein the collecting mirror seat is arranged above the lamp holder, the second collecting mirror is arranged in the collecting mirror seat, the manual-control adjusting seat is sleeved above the collecting mirror seat, the rotating pin is arranged at the bottom of the manual-control adjusting seat, and an optical grating sheet is arranged at the joint between the manual-control adjusting seat and the collecting mirror assembly and provided with a waist-shaped groove matched with the rotating pin. The dual-slit lamp lighting device further comprises a slit lamp, wherein the entrance end of the slit lamp is inserted into the collecting mirror seat through light guide fibers and connected with the second collecting mirror through the optical grating sheet. Compared with the prior art, the dual-slit lamp lighting device has the advantages that a second path of light guide fiber is additionally arranged for lighting under the condition that the same light source is used, so that the lighting range for the tissue surrounding eyes is increased.
Description
Technical field
This utility model relates to a kind of microscopical illuminator, specifically the auxiliary lighting apparatus of a kind of microscope slit lamp when checking and throw light on.
Background technology
The crack illuminator is the vitals of slit lamp microscope.The crack illumination is with being projected to patient's eye after the line focus of single channel light, so that microscopy.
In examination with slitlamp microscope, the single channel slit of illumination is when illumination, and its light source can only be radiated at the local location of eye, and the peripheral part of eye is aobvious gloomy without illumination.When slit lamp photography, the perienchyma of eyes can not imaging because of the nothing illumination except the crack like this.
Summary of the invention
This utility model provides a kind of two-way slit lamp illuminator in order to overcome the deficiencies in the prior art.
To achieve these goals, this utility model has designed a kind of two-way slit lamp illuminator, comprise by lamp socket, the first condenser lens, the first focus lamp group that lighting source forms, it is characterized in that: also comprise second a focus lamp group, the second focus lamp group comprises and is arranged on lamp socket top, and the optically focused microscope base of partial insertion in lamp socket, and be arranged on the interior second condenser lens of optically focused microscope base, also comprise the manual adjustment seat that is set in optically focused microscope base top, and the rotational pin that is arranged on manual adjustment seat bottom, the junction of manual adjustment seat and condenser lens group arranges lenticular lenses, and lenticular lenses cooperates rotational pin that waist type groove is set; Also comprise a slit lamp, and be used for the fixedly crack lamp socket of slit lamp that the end of injecting of slit lamp is connected with second condenser lens in optical fibers inserts the focusing microscope base and through lenticular lenses.
Sheathed rubber ring on the cylindrical of described manual adjustment seat.
Described rubber ring is three groups.
This utility model is compared with prior art, on original single channel slit lamp illuminator, increase an auxiliary lighting apparatus, in the situation of using the same light source, the slit lamp illuminator is increased the illumination of the second road optical fibers on the basis of single channel projection illumination, thereby increased the illumination zone to eyes perienchyma, reached good imaging effect.
Description of drawings
Fig. 1 is the optical principle block diagram of existing slit lamp microscope.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the optical principle block diagram of slit lamp microscope of the present utility model.
Referring to Fig. 2,1 is lamp socket; 2 is the optically focused microscope base; 3 is second condenser lens; 4 is manual adjustment seat; 5 is rotational pin; 6 is lenticular lenses; 7 is waist type groove; 8 is slit lamp; 9 is the crack lamp socket; 10 is optical fibers; 11 is rubber ring; 12 is lighting source; 13 is 45 degree reflecting mirrors; 14 is patient's eye.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described.
As shown in Figure 1, be existing slit lamp microscope optical principle block diagram, when the patient in examination with slitlamp microscope, lighting source is radiated on the reflecting mirror of 45 degree by the condenser lens group, again through reflecting mirror according to to patient's eye, because just it can only shine the local area of eye with the lighting source of single channel, and the peripheral part of eye is aobvious gloomy without illumination.When slit lamp photography, the perienchyma of eyes can not imaging because of the nothing illumination except the crack like this.
As shown in Figure 2, this utility model comprises by lamp socket, the first condenser lens, the first focus lamp group that lighting source forms, also comprise second a focus lamp group, the second focus lamp group comprises and is arranged on lamp socket 1 top, and the optically focused microscope base 2 of partial insertion in lamp socket 1, and be arranged on second condenser lens 3 in the optically focused microscope base 2, also comprise the manual adjustment seat 4 that is set in optically focused microscope base 2 tops, and the rotational pin 5 that is arranged on manual adjustment seat 4 bottoms, manual adjustment seat 4 arranges lenticular lenses 6 with the junction of condenser lens group 2, and lenticular lenses 6 cooperates rotational pin 5 that waist type groove 7 is set; Also comprise a slit lamp 8, and be used for the fixedly crack lamp socket 9 of slit lamp 8 that the end of injecting of slit lamp 8 is connected with second condenser lens 3 in optical fibers 10 inserts focusing microscope base 2 and through lenticular lenses 6.Also be arranged with three groups of rubber rings 11 in the present embodiment on the cylindrical of manual adjustment seat 4.
As shown in Figure 3, optically focused microscope base 2 of the present utility model is screwed on the lamp socket 1 of the first condenser lens group of slit lamp microscope.After lighting source focuses on light by the first focus lamp group, through 45 degree reflecting mirrors, 13 reflection back lighting patient eyes 14.Because slit lamp 8 is same light source and same 45 degree reflecting mirrors 13 with lighting source 12 employings, reflection ray is on coaxial position.On the manual adjustment seat 4 grating rotational pin 7 is housed in addition, rotational pin 5 just in time snaps in the waist-shaped hole 7 on the lenticular lenses 6 when rotating manual adjustment seat 4.Lenticular lenses 6 is rotated thereupon, the size of scalable slit lamp 8 luminous fluxes, the power of controlled light.Scald hands for the heat that prevents the high light generation is transferred on the manual adjustment seat 4, in manual adjustment seat 2 three slat gum circles 11 are housed, can play heat-blocking action, prevent from scalding.
Compare with prior art, on original single channel slit lamp illuminator, increase an auxiliary lighting apparatus, in the situation of using the same light source, the slit lamp illuminator is increased the illumination of the second road optical fibers on the basis of single channel projection illumination, thereby increased the illumination zone to eyes perienchyma, reached good imaging effect.
