Miniature intraocular lens push broach

Abstract

The invention relates to a miniature intraocular lens push broach. The miniature intraocular lens push broach comprises a blade part and a handle part, and the blade part and the handle part are integrally connected; the handle part is integrally formed by an operating end and an extending end, and an inclined included angle of 135 degrees is formed between the operating end and the extending end; and the operation end and the blade part are horizontally arranged and are integrally connected. The miniature intraocular lens push broach has the advantages that the miniature intraocular lens push broach is simple in structure and convenient to operate, can smoothly enter a capsule without enlarging a corneal incision, and is sharp in scalpel face and not prone to being broken off; and meanwhile, the width of the blade part is consistent with the thickness of the optical part of the intraocular lens, so that the blade part can wrap the intraocular lens for rapid push-cutting, the residual piece of the intraocular lens can be rapidly taken out under the condition that the capsular membrane is not damaged, the injury during an operation is reduced, and the operation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of ophthalmic surgical instruments, in particular to a miniature intraocular lens push knife. Background technique [0002] With the increase of human age, the incidence of cataract is increasing year by year. The main pathological change of cataract is that the lens becomes hard and cloudy, which needs to be replaced by artificial lens. Currently the most widely used is the foldable IOL, which can be inserted through a small incision and then unfolded. In clinical practice, if the intraocular lens haptics are broken, the optical zone is damaged, etc., or the implanted intraocular lens is found to have an error in the power of the implanted intraocular lens, the intraocular lens needs to be removed or replaced, but the implanted intraocular lens cannot be folded again , so the required surgical incision is relatively large, which is likely to cause surgical complications. At the same time, the use of tradi...
