Technical Field
The invention relates to a photographic auxiliary device used on a slit-lamp microscope.
Background
In the ophthalmologic examination, a slit lamp microscope can be used for amplifying pathological change details and observing the deep eye condition which can not be seen by the naked eye. Therefore, slit-lamp microscopes are commonly used in ophthalmic disease examinations. However, when the slit-lamp microscope is used for examining ophthalmic diseases, only one person can observe images under the microscope in real time, and the slit-lamp microscope does not have the function of image recording. The following methods are often used to record the under-lens image of a slit-lamp microscope, but all suffer from some disadvantages.
A digital slit-lamp microscope: the working principle of the digital slit-lamp microscope is a slit-lamp microscope with a camera and an image display system. When the digital slit-lamp microscope is used for observing the images under the glasses through the two eyes, the camera transmits image digital signals to the computer, the images under the glasses observed by the two eyes on the ocular are synchronously displayed on the computer screen, and the observed images under the glasses can be recorded. But it has limitations of high cost and large volume. Clinically, a slit-lamp microscope is used as a basic device for ophthalmic examination, and in an ophthalmic outpatient service, one slit-lamp microscope needs to be configured for each outpatient service doctor, and a plurality slit-lamp microscopes also need to be configured in an ophthalmic ward at the same time, so that the dosage is large. If the digital slit-lamp microscope is completely used for replacing the slit-lamp microscope, the purchase cost of the equipment is increased by a little. Meanwhile, a large number of existing slit-lamp microscopes are left unused, causing unnecessary waste. In addition, the digital slit-lamp microscope has a large volume, and places for a large number of digital slit-lamp microscopes in hospitals are difficult to find.
