Abstract
The invention discloses a kind of anterior ocular segment and check camera lens, comprising: focusing lens group, focusing motor and fixing object lens, described focusing motor is arranged on the top of focusing lens group, and described fixing object lens are arranged on the rear of focusing lens group; The light reflected by the eye table of eyeball carries out focusing by focusing lens group to be reduced or amplification imaging size, through fixing object lens imaging.By the way, the present invention can complete electrodeless zoom, dismantles flexibly, and highly versatile.
Description
Technical field
The present invention relates to technical field of medical instruments, particularly relate to a kind of anterior ocular segment and check camera lens.
Background technology
In medical-ophthalmologic field, anterior ocular segment specifically comprises: all cornea, iris, corpus ciliare, anterior chamber, back room, apparatus suspensorius lentis, Fang Jiao, part crystalline lens, periphery vitreous body, retina and extraocular muscles attachment point portion and conjunctivas etc.At present for checking that the camera lens of anterior ocular segment is combining by lens or several lens, its camera lens itself cannot be focused, and needs to carry out manual focusing, inconvenient operation by means of other instruments, and cannot use flexibly, lens function is single.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of anterior ocular segment and checks camera lens, and self is accompanied with focusing component, can complete electrodeless zoom.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of anterior ocular segment to check camera lens, comprise: focusing lens group, focusing motor and fixing object lens, described focusing motor is arranged on the top of focusing lens group, described fixing object lens are arranged on the rear of focusing lens group, the light reflected by the eye table of eyeball carries out focusing by focusing lens group to be reduced or amplification imaging size, through fixing object lens imaging.
In a preferred embodiment of the present invention, what check camera lens and other adnexa for making anterior ocular segment coordinates versatility more by force, and the rear of described fixing object lens is provided with control circui line port, and described control circui line port is connected with the digital camera of infrared receiver.
The invention has the beneficial effects as follows: anterior ocular segment of the present invention checks that camera lens inside self is accompanied with focusing lens group and focusing motor, and can carry out electrodeless zoom, operator only needs replacing examination of ocular fundus camera lens, and can complete assembling, easy to operate, replaceability is strong.
Accompanying drawing explanation
Fig. 1 is the structure principle chart that anterior ocular segment of the present invention checks camera lens;
Fig. 2 is the mounting structure schematic diagram that anterior ocular segment of the present invention checks camera lens.
In accompanying drawing, the labelling of each parts is as follows: 1, focusing lens group; 2, focusing motor; 3, fixing object lens; 4, control circui line port; 5, digital camera; 6, anterior ocular segment somascope; 7, slit lamp; 8, focusing button; 9, shutter release button; 10, eyeball.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1 and Fig. 2, the embodiment of the present invention comprises: a kind of anterior ocular segment checks camera lens, comprising: focusing lens group 1, focusing motor 2 and fixing object lens 3, and focusing motor 2 is arranged on the top of focusing lens group 1, and fixing object lens 3 are arranged on the rear of focusing lens group 1; The light reflected by the eye table of eyeball 10 carries out focusing by focusing lens group 1 to be reduced or amplification imaging size, and through fixing object lens 3 imaging.
Furtherly, the rear of described fixing object lens 3 is provided with control circui line port 4, and control circui line port 4 is connected with the digital camera 5 of infrared receiver.
Please again consult Fig. 2, anterior ocular segment of the present invention checks that camera lens integrates focusing and micro-imaging, reach two item functions of focusing and imaging, only anterior ocular segment need be checked that camera lens is installed on the relevant position of camera lens in supporting anterior ocular segment somascope 6 in use, anterior ocular segment checks that the control circui line port 4 of camera lens rear end is connected with the digital camera 5 with infrared receiver, to anterior ocular segment, eyeball 10 checks that camera lens is looked through slit lamp 7, anterior ocular segment checks that camera lens coordinates slit lamp 7 to complete light path imaging, operator is by observing the eye telogenesis picture on digital camera 5 screen, press the focusing button 8 of anterior ocular segment somascope 6 by time extremely the most clear for the focusing of eye telogenesis picture, start shutter release button 9, digital camera 5 can complete last imaging and take pictures.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
