Abstract
The invention discloses a lens for examining anterior segment, which comprises a focusing lens group, a focusing motor and a fixed objective lens, wherein the focusing motor is arranged above the focusing lens group; the fixed objective lens is arranged at the rear of the focusing lens group; and the light reflected by the ocular surface of an eyeball is focused by the focusing lens group so as to reduce or enlarge the imaging size, and the fixed objective lens is used for imaging. In this way, the lens can realize stepless zoom and is flexible to disassemble and high in universality.
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 the medical science field of ophthalmology, anterior ocular segment specifically comprises: whole corneas, iris, corpus ciliare, anterior chamber, back room, apparatus suspensorius lentis, Fang Jiao, part crystalline lens, peripheral vitreous body, retina and extraocular muscles attachment point section and conjunctiva etc.The camera lens that is used at present checking anterior ocular segment is that itself can't focus its camera lens, need to carry out manual focusing by means of other instruments by the combining of lens or several lens, and inconvenient operation can't be used flexibly, and lens function is single.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of anterior ocular segment and checks camera lens, and self is accompanied with focusing component, can finish 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 fixedly object lens are arranged on the rear of focusing lens group, focused by the focusing lens group by the light of the eye table reflection of eyeball and to dwindle or the amplification imaging size, through fixedly object lens imaging.
In a preferred embodiment of the present invention, cooperate versatility stronger for what make that anterior ocular segment checks camera lens and other adnexa, be provided with the circuit controling line road port at the rear of described fixedly object lens, described circuit controling line road port is connected with the digital camera of infrared reception.
The invention has the beneficial effects as follows: anterior ocular segment of the present invention checks inner focusing lens group and the focusing motor of self being accompanied with of camera lens, can carry out electrodeless zoom, and the operator only need to change an examination of ocular fundus camera lens, can finish assembling, and easy to operate, replaceability is strong.
Description of drawings
Fig. 1 is the structure principle chart that anterior ocular segment of the present invention checks camera lens;
Fig. 2 is the mounting structure sketch map that anterior ocular segment of the present invention checks camera lens.
The labelling of each parts is as follows in the accompanying drawing: 1, focusing lens group; 2, focusing motor; 3, fixing object lens; 4, circuit controling line road port; 5, digital camera; 6, anterior ocular segment somascope; 7, slit lamp; 8, focusing button; 9, shutter release button; 10, eyeball.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also Fig. 1 and Fig. 2, the embodiment of the 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 fixedly object lens 3 are arranged on the rear of focusing lens group 1; Focused by focusing lens group 1 by the light of the eye table reflection of eyeball 10 and to dwindle or the amplification imaging size, and through fixedly object lens 3 imagings.
Furtherly, be provided with circuit controling line road port 4 at the rear of described fixedly object lens 3, circuit controling line road port 4 is connected with the digital camera 5 of infrared reception.
Please again consult Fig. 2, anterior ocular segment of the present invention checks that camera lens integrates focusing and micro-imaging, two functions of focusing and imaging have been reached, only need in use anterior ocular segment is checked that camera lens is installed on the relevant position of camera lens in the supporting anterior ocular segment somascope 6, anterior ocular segment checks that the circuit controling line road port 4 of camera lens rear end is connected with the digital camera 5 with infrared reception, eyeball 10 sees through slit lamp 7 and looks to anterior ocular segment inspection camera lens, anterior ocular segment checks that camera lens cooperates slit lamp 7 to finish light path imaging, the operator is by observing the eye telogenesis picture on digital camera 5 screens, the focusing button 8 of pressing anterior ocular segment somascope 6 with the focusing of eye telogenesis picture when the most clear, start shutter release button 9, digital camera 5 can be finished last imaging and take pictures.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes description of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
Claims (2)
1. an anterior ocular segment checks camera lens, it is characterized in that, comprising: focusing lens group, focusing motor and fixing object lens, and described focusing motor is arranged on the top of focusing lens group, and described fixedly object lens are arranged on the rear of focusing lens group; Focused by the focusing lens group by the light of the eye table reflection of eyeball and to dwindle or the amplification imaging size, through fixedly object lens imaging.
2. anterior ocular segment according to claim 1 checks camera lens, and it is characterized in that: be provided with the circuit controling line road port at the rear of described fixedly object lens, described circuit controling line road port is connected with the digital camera of infrared reception.
