Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to a fundus wide-angle observation mirror with a protective cover. Background Art
[0002] The non-contact fundus wide-angle observation mirror, referred to as the fundus wide-angle mirror, is used for vitreoretinal surgery in ophthalmology without contacting the cornea. It provides the best image of the vitreous cavity, a panoramic view of the fundus with a viewing angle of up to 130°, which increases the operator's viewing angle and facilitates the observation of object details.
[0003] However, during the operation, the doctor's hands wearing sterile gloves have to operate the wide-angle lens. After touching the unsterilized wide-angle lens, the sterile gloves will be contaminated, which is easy to cause infection of the patient's operated eye during the next operation. Therefore, when the wide-angle lens is used during the operation, high-pressure steam sterilization is required, which leads to high cost, more troublesome use, and reduced use effect.
