Problems solved by technology
In practice, the ophthalmoscope is frequently used, and doctors need to carry out corresponding examinations for each patient. The existing binocular ophthalmoscope adopts a rotating double gear type to adjust the angle of the optical part and the tightness of the head-mounted part. The gears are severely worn and can no longer be fixed effectively, seriously affecting the use effect

The invention relates to the field of medical apparatuses and instruments, in particular to a binocular indirection ophthalmoscope with the angle convenient to adjust. The binocular indirection ophthalmoscope comprises a head-mounted device, an adjusting device and an optical device. The adjusting device comprises a connecting base and an adjusting connector. One end of the connecting base is fixedly connected with the two ends of a transverse fixing component, and the other end of the connecting base is hinged to one end of the adjusting connector. The other end of the adjusting connector is fixedly connected with the optical device. A plurality of tooth sockets are arranged on the connecting base. The adjusting device is provided with a limiting spring, a first containing space and a second containing space. A limiting block is arranged in the first containing space, one end of the limiting spring is connected with the positioning block in an abutting mode, and the other end of the limiting spring is connected with the bottom of the first containing space in an abutting mode; the end, opposite to the end connected with the limiting spring in the abutting mode, of the positioning block is connected with the tooth space to form clamping; the second containing space is provided with an adjusting button, and the adjusting button controls the positioning block to move downwards. The binocular indirection ophthalmoscope is simple and durable in structure, and has the good fixing effect, and the control method is simple.
Description
【Technical field】 [0001] The invention relates to the field of medical equipment, in particular to a binocular indirect ophthalmoscope for convenient angle adjustment. 【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 correspo...
