Abstract
The utility model relates to an assistive device for the slit lamp microscope, in particular to a digital switching device for a slit lamp microscope. The digital switching device is structurally characterized in that a first lens barrel and a second lens barrel are fixedly connected through a retaining screw; the second lens barrel and a third lens barrel are connected in an insertion manner; a microscope bayonet connection device is arranged on an optical splitter; the optical splitter is connected with the first lens barrel; a beam splitter prism is connected with a beam splitter prism fixing device through a gasket; the beam splitter prism fixing device is connected with the microscope bayonet connection device; an imaging cementation lens is arranged at the end part of the second lens barrel; and a clamping ring is connected with the second lens barrel so as to fix the cementation lens. When the digital switching device is used, the microscope bayonet connection device is connected with the microscope, and the third lens barrel is connected with a digital camera, so that the digital switching device can be operated by one person, an eye image of a patient can be observed more intuitively and clearly, and the image can be displayed and saved dynamically and synchronously.
Description
Technical field
This utility model relates to a kind of slit lamp microscope auxiliary implement, is a kind of switching device of slit lamp microscope numberization specifically.
Background technology
The principle of slit lamp microscope promptly is to concentrate making full use of of light.After light was sent by strong and concentrated light source, the projection of the condenser lens by in groups was in focus place light high concentration.When the structure of this light of concentrating through having a look at, only light is illuminated by the tissue of locating, and its position that is illuminated just is consistent with the size and the shape of light section, and is located to be had tangible contrast according to the place with dark around it.By the microscopic system amplification imaging pathological changes of deep tissue also can clearly be manifested again, observe the state of an illness for the doctor.
But the initial audit function of traditional slit lamp biomicroscope can only be observed by eyepiece one people, and the case history image can't be kept on file, can not satisfy the needs of current clinical medicine development, particularly in the many people teaching and the consultation of doctors, form the obstacle that is difficult to break through.
Summary of the invention
The purpose of this utility model provides a kind of switching device of slit lamp microscope numberization, by this device can external microscope, equipment such as digital camera, can be under the situation of people's operation, can observe patient's eyes image more directly perceived, more clearly, and the dynamic synchronization display image is preserved image.
The purpose of this utility model is achieved through the following technical solutions: the switching device of slit lamp microscope numberization, it is characterized in that: first lens barrel is fixedlyed connected by fixed screw with second lens barrel, second lens barrel inserts with trinocular tube and is connected, the microscope bayonet mount is housed on beam splitter, beam splitter is connected with first lens barrel, Amici prism is connected with the Amici prism fixture by pad, the Amici prism fixture is connected with the microscope bayonet mount, be provided with imaging gummed mirror in the second lens barrel end, trim ring is connected with second lens barrel fixes the gummed mirror.
The described first lens barrel tail end is provided with fixed screw.
The beneficial effects of the utility model: this utility model adopts said structure, needn't buy the slit lamp whole system again, can reach the purpose of repacking, during use with the switching device of this slit lamp microscope numberization, be connected with microscope by the microscope bayonet mount, trinocular tube is connected with digital camera, reduced lens numbers in the lens barrel, do not influence image quality, light is passing through the Amici prism beam split after passing through microscopical preceding object lens, a part does not change direction through Amici prism, imaging on the human eye through eyepiece, another part changes direction through Amici prism and images on the digital camera CCD through imaging gummed mirror, reaches the purpose that image output is preserved.Adopt external shutter to link to each other with electric-controlled switch on the slit lamp handle, can reach personnel's visualization on one side patient, press the electric-controlled switch on the slit lamp handle on one side, the control shutter, reaches the purpose of people's independent operation at the grasp photograph time.Also can be as required, the delivery outlet of digital camera is connected with computer processing system through data wire, index path is looked like to be converted into digital information, and send to described computer processing system, reach the effect that image output shows, can be on camera display screen and computer monitor show synchronously, can clear observation patient eye situation, be convenient to watch, preserve.The plural consultation of being more convenient for, the storage of patient information data and image also provide foundation for patient can know the state of an illness of understanding oneself more or better solve the related medical dispute.
Description of drawings
Fig. 1 is the overall appearance sketch map of this utility model embodiment.
Fig. 2 is the overall assembling cross-sectional schematic of this utility model embodiment.
The specific embodiment
Also in conjunction with the accompanying drawings this utility model is described in further detail below by specific embodiment.
The switching device of slit lamp microscope numberization, as shown in Figure 1, 2, first lens barrel 6 is connected with second lens barrel 9 by fixed screw 7 and connects, second lens barrel 9 inserts with trinocular tube 11 and is connected, microscope bayonet mount 1 is housed on beam splitter 5, beam splitter 5 is connected with first lens barrel 6, Amici prism 4 is connected with Amici prism fixture 2 by pad 3, Amici prism fixture 2 is connected with microscope bayonet mount 1, imaging gummed mirror 8 is installed in the end of second lens barrel 9, and fixing with trim ring 10.Be provided with fixed screw 7 at first lens barrel, 6 tail ends.During use, microscope is connected with microscope bayonet mount 1, and trinocular tube 11 links to each other with the camera that is complementary.Adopt the camera data line to be connected with computer, employing software control camera images acquired adopts external shutter to link to each other with electric-controlled switch on the slit lamp handle, can reach personnel's visualization on one side patient, press the electric-controlled switch on the slit lamp handle on one side, the control shutter is grasped the photograph time.
In addition also can be as required be provided with fixed screw 12, as the external equipment expansion or replace standby at the tail end of first lens barrel 6.
