Abstract

The invention discloses a vitreous cut lens ring providing fundus illumination and an application method thereof, the lens ring comprises a ring body, a lens slot and a wireless energy feeding circuit, the ring body is a hollow hemispherical surface, and the curvature radius of the hollow hemispherical surface is in line with an eyeball; the lens slot is arranged at the top center of the convex side of the ring body. The wireless energy feeding circuit comprises a receiving coil and light emitting elements; the receiving coil is arranged on the inner wall side of the concave side of the ring body; the light-emitting elements are distributed in a ring at the specified position of the ring body, and the specified position corresponds to the inner cornea of a human body; the receiving coil iselectrically connected with the light emitting elements. The lens ring can be used for intraocular surgery, and is fixed directly in front of an eye and is powered by wireless energy feeding. According to the invention, a light source does not need to be inserted into the eyeball or close to the outer wall of the eyeball, so as to avoid secondary injury to the patient and reduce the operation complexity.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a vitrectomy lens ring for providing fundus illumination and an application method thereof. Background technique [0002] Fundus surgery requires different lenses to be placed in front of the cornea to observe different positions of the fundus during intraocular surgery. In order to stabilize the lens and facilitate lens replacement, a ring is fixed in front of the eye to carry various lenses. In addition, in order to illuminate the fundus during the operation, a light source is also inserted into the eyeball or attached to the outer wall of the eyeball. Inserting the eyeball will cause further damage, and the outer wall of the eyeball needs to be sutured for fixation, which is not only complicated to operate, but also causes certain injuries. Therefore, how to avoid secondary injuries during intraocular surgery and reduce the complexity of surgery is of great significan...
