Title:
AUTOMATIC AND MANUAL ZOOM MECHANISM FOR SLIT LAMP-BASED DRY EYE INSPECTION INSTRUMENT
Document Type and Number:
WIPO Patent Application WO/2022/096032
Kind Code:
A1
Abstract:
An automatic and manual zoom mechanism for a slit lamp-based dry eye inspection instrument, comprising an optical body zoom drum seat (304), an optical body zoom drum (306), zoom hand wheels (301, 309), and an electric drive mechanism. The optical body zoom drum (306) is mounted in the optical body zoom drum seat (304), and two ends of the optical body zoom drum (306) are respectively connected to the zoom hand wheels (301, 309) by means of a connecting shaft. The electric drive mechanism is arranged on the optical body zoom drum base (304), and the electric drive mechanism is used for driving the optical body zoom drum (306) to rotate. The effects of such a zoom mechanism are: first, the structure is simple and implementation of a Galileo optical system slit lamp and an automatic zoom function of a slit lamp-type dry eye inspection instrument is facilitated; second, at the same time that the automatic zoom function of the Galileo optical system slit lamp is implemented, and a manual zoom function is also preserved; and third, implementation of intelligent operation and remote operation of the whole slit lamp and the slit lamp-type dry eye inspection instrument is facilitated.
