Description

Binocular ophthalmoscope

Technical Field

The utility model relates to the field of ophthalmoscopes, in particular to a binocular ophthalmoscope.

Background

Ophthalmoscopes are the most common medical equipment for clinical fundus examination, and can be divided into direct ophthalmoscopes and indirect ophthalmoscopes. The direct ophthalmoscope is an intuitive fundus observation device which is used earlier, but has no stereoscopic impression, shorter inspection range, smaller visual field and lower illumination brightness, so the application range is smaller. Indirect ophthalmoscopes, in particular binocular indirect ophthalmoscopes, have good stereoscopic impression, large visual field and high illumination brightness, overcome the defects of direct ophthalmoscopes to a considerable extent, and become the current preferred medical equipment for fundus examination. The use of ophthalmoscopes has become a fundamental work for ophthalmologists, U.S. patent publication No. US20080252851, which sets forth the imaging mechanism of binocular indirect ophthalmoscopes. The binocular ophthalmoscope forms an inverted image at the observation position through secondary imaging of the ocular lens and the objective lens. This causes the ophthalmologist to need to take an operation opposite to the observation direction in the eye surgery using the binocular indirect ophthalmoscope, which brings great inconvenience to the ophthalmologist. Chinese patent publication No. CN 110353627 a discloses a binocular ophthalmoscope which solves the problem of forming an inverted image at the observation site and can directly observe the upright image of the fundus of a patient. Chinese patent publication No. CN102397054 discloses an "LED-illuminated binocular indirect ophthalmoscope", which proposes to use an LED as an illumination light source to improve the illumination defect of the binocular indirect ophthalmoscope. Chinese patent publication No. CN106551675 discloses a binocular indirect ophthalmoscope with a polarization function, which proposes to use a polarization device to reduce stray light so as to improve imaging sharpness. However, the ophthalmoscopes formed by the above-mentioned patents have no function of assisting teaching, that is, the intern cannot observe with the lecturer synchronously, the lecturer cannot teach and correct the operation of examining the eyes of the intern in time, the training efficiency of the intern is low, and the training cost is increased.
