A visual anterior segment inspection instrument

Abstract

The invention discloses a visible anterior segment inspection tester which comprises an anterior segment inspection lens, a slit lamp and a tester body. A data transmission interface and a first circuit control line port are arranged on a tail of the tester body, a digital camera receiving infrared rays and a second circuit control line port are arranged on a head of the tester body, a fourth circuit control line port is arranged on a tail of the slit lamp, and the slit lamp is connected with the tester body through the butt joint of the first circuit control line port and the fourth circuit control line port. The anterior segment inspection lens comprises a focusing lens group, a focusing motor and a fixed objective lens, wherein a third circuit control line port is arranged on the back of the fixed objective lens, and the anterior segment inspection lens is connected with the digital camera through the butt joint of the second circuit control line port and the third circuit control line port. Lights reflected by an ocular surface of an eyeball are focused by the focusing lens group, and are imaged on the digital camera through the fixed objective lens. By means of the visible anterior segment inspection tester, ocular surface imaging pictures can be seen visually and can be shot accurately, thus the ocular image is stored and printed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a visual anterior segment inspection instrument. Background technique [0002] In the field of medical ophthalmology, the anterior segment specifically includes: the entire cornea, iris, ciliary body, anterior chamber, posterior chamber, lens zonule, chamber angle, part of the lens, peripheral vitreous body, retina and extraocular muscle attachment points and conjunctiva, etc. At present, when the traditional anterior segment (also known as ocular surface) inspection instrument is operated, the examinee performs ocular surface imaging through the anterior segment inspection mirror and slit lamp, and the operator needs to align his eyes with a pair of microscopes to see the fundus imaging. Since the operator's eyes are always facing the microscope lens when viewing the ocular surface imaging, visual fatigue is likely to occur when the operation takes a long time, and the d...

Problems solved by technology

At present, when the traditional anterior segment (also known as ocular surface) inspection instrument is operated, the examinee performs ocular surface imaging through the anterior segment inspection mirror and slit lamp, and the operator needs to align his eyes with a pair of microscopes to see the fundus imaging. Since the operator's eyes are always facing the microscope lens when viewing the ocular surface imaging, visual fatigue is likely to occur when the operation takes a long time, and the diagnostic results may not be accurate enough. In addition, the diagnostic results are manually recorded, and the inspection instrument itself does not automatically record or is the storage function
