Description
【Technical field】 [0001] The invention relates to the field of medical equipment, in particular to a conveniently adjustable binocular indirect ophthalmoscope fixing device. 【Background technique】 [0002] Fundus examination is one of the routine examination items in ophthalmology, and ophthalmoscope is an essential medical optical instrument in fundus examination. It is usually divided into two types: direct ophthalmoscope and indirect ophthalmoscope. The inspection distance of direct ophthalmoscope is short, the field of view is small, The illumination is low, and its scope of use is limited; binocular indirect ophthalmoscopy can obtain good stereoscopic vision, and has the advantages of large depth of field, clear imaging, teaching, photographing, and video recording, so binocular indirect ophthalmoscopy It has become the most convenient and superior fundus examination method at present. In practice, the ophthalmoscope is frequently used, and doctors need to carry out co...
