Abstract
The invention discloses a slit lamp microscope, which has a base. An auxiliary seat capable of moving longitudinally/transversely is arranged on the base; the auxiliary seat supports a microscope seat through a height regulating device; the upper end of the microscope seat is provided with a bracket shaft; a light source device capable of rotating around the bracket shaft and a microscopic imaging device are respectively arranged on the bracket shaft; an eyepiece and an objective are integrated with the microscopic imaging device into a whole; a mechanism capable of moving relatively is arranged between the microscope seat and the bracket shaft; and the mechanism moving relatively is a kinematic pair forming a circular arc track by taking a focus as a circle center, taking a move surface distance from the focus to a trajectory as a radius and taking a moving block as a moving point. The microscope can allow doctors to conveniently realize overlooking or up-looking observation on the lesions of patients at required angles by means of instruments, so as to realize omnidirectional observation on the lesions of the patients by means of the instruments.
Description
The microscope that technical field the present invention relates to medically use directly relates to the used slit lamp microscope of medical science ophthalmology.
The background technology slit lamp microscope is one of the most general instrument of present ophthalmic applications, has the irreplaceable effect of other instruments for the ocular disease of observing patient.The doctor can adjust instrument and realize that the three-dimensional that vertically, laterally reaches vertical direction moves according to patient's concrete condition when observing patient's focus, and simultaneously, light supply apparatus, the microscopic imaging device that also can adjust wherein move around vertical axis respectively.Yet when need be to patient from certain depression angle or when looking up angle and observing focus, have to allow patient change down or in an instant eyeball just can finish, sometimes this requirement is difficult to the effect that reaches satisfied, and is especially all the more so when running into heavier patient of the state of an illness or child.
Summary of the invention purpose of the present invention will provide a kind of improved slit lamp microscope exactly, and it can overcome existing slit lamp microscope effectively can't directly overlook or look up the problem of observing patient's focus.
The object of the present invention is achieved like this: slit lamp microscope has base, being provided with on the base can be vertical, laterally mobile counter-base, counter-base supports microscope base by arrangement for adjusting height, microscope base upper end mounting bracket axle, the light supply apparatus and the microscopic imaging device that can rotate around support shaft are installed respectively on support shaft, eyepiece and object lens and microscopic imaging device form one, relatively-movable mechanism is set between described microscope base and the support shaft, and this mechanism that relatively moves is to be the center of circle with the focus, is radius with focus to the distance of track translational surface, form the kinematic pair of arc track for moving point with movable block.
As further scheme of the present invention be: described kinematic pair is for setting the sliding friction pair or the rolling friction pair of track.
The present invention is the center of circle owing to being provided with between microscope base and support shaft with the focus, is radius, is a moving some kinematic pair that forms arc track with movable block with the distance of focus to the track translational surface, thereby can make the doctor observation be overlooked or be looked up to the angle that patient's focus is conveniently implemented in requirement, thereby realize by the comprehensive observation of instrument to patient's focus by instrument.
Appended drawings is a structure principle chart of the present invention, and the invention will be further described below in conjunction with accompanying drawing.
Specific embodiment accompanying drawing shows the structure of slit lamp microscope of the present invention, counter-base 11 can be realized on base 12 vertically, horizontal moves, arrangement for adjusting height 10 links up counter-base 11 and microscope base 9, and make the part of microscope base more than 9 realize moving of vertical with respect to counter-base 11, being provided with focus 1 between microscope base 9 and the support shaft 14 is the center of circle, is radius with focus 1 to the distance of track 8 translational surfaces, form the kinematic pair of arc track for moving point with movable block 13, track 8 can be arranged on the microscope base 9, correspondingly movable block 13 just is arranged on the support shaft 14, otherwise, track 8 also can be arranged on the support shaft 14, correspondingly movable block 13 just should be arranged on the microscope base 9, light supply apparatus 2 and the microscopic imaging device 4 that can distinguish relative support shaft 14 rotations are installed on support shaft 14, light supply apparatus 2 is by light source bracket 6 supportings, microscopic imaging device 4 is by 7 supportings of micro-imaging support, eyepiece 5 and object lens 3 form one with microscopic imaging device 4, when patient was implemented to observe, observed patient's eyes were positioned at focus 1 place.
Described kinematic pair is sliding friction pair or the rolling friction pair that sets on the arc track, also can be the pitch wheel revolute pair.
Can make object lens 3 be positioned at the dead ahead of the observed eyes of patient by adjusting vertical, horizontal, three directions of vertical, be implemented in patient's eyes side certain angle observation of use instrument by rotation light supply apparatus 2 and microscopic imaging device 4, patient's eyes overlooked or look up observation by adjusting under the relative position realization certain angle between movable block 13 and the track 8 with instrument.
