Abstract

A binocular ophthalmoscope belongs to the technical field of medical instruments. In order to solve the problem that the existing ophthalmoscope can only form an inverted image, the ophthalmoscope is composed of a first lens, a first reflecting mirror, a first Schmidt roof prism, a second Mirror, third mirror, fourth mirror, fifth mirror, second lens, sixth mirror, seventh mirror, eighth mirror, second Schmidt roof prism, ninth mirror and The optical system composed of the third lens is arranged in the casing; the lighting system A is fixed on the upper part of the casing through the connecting rod with the first rotating shaft and the second rotating shaft, and is used for illuminating the eyeball; the lighting system B is arranged on the casing, and the The light is incident on the fifth reflector, reflected by the fifth reflector and then incident on the eyeball; applied to fundus surgery, after wearing this binocular ophthalmoscope, the doctor can directly observe the upright image of the patient's fundus without special training. Can shorten physician training time and reduce training costs.

Description

technical field [0001] The invention relates to a binocular ophthalmoscope, which is applied to the observation and operation of ophthalmic diseases and belongs to the technical field of medical instruments. Background technique [0002] Ophthalmoscope is the most commonly used medical equipment for clinical fundus examination, and the use of ophthalmoscope has become the basic skill of ophthalmologists. Ophthalmoscopy can be divided into two types: direct ophthalmoscopy and indirect ophthalmoscopy. Direct ophthalmoscope is a kind of visual fundus observation equipment that was used earlier, but it has no three-dimensional effect, short inspection range, small field of view, and low illumination brightness, so its application range is small. Indirect ophthalmoscope, especially binocular indirect ophthalmoscope, has good three-dimensional sense, large field of view, and high illumination brightness. [0003] The US patent with publication number "US20080252851" clarifies th...
