Description

Rod-shaped crystal wire ring

Technical Field

The utility model relates to the technical field of ophthalmic surgery equipment, in particular to a rod-shaped crystal wire ring.

Background

Intraocular lenses are currently the most effective means of correcting the refraction of aphakic eyes, replacing the original lens anatomically and optically, and forming a near-normal system, particularly posterior chamber intraocular lenses, fixed in the physiological position of the normal lens. Can be used for monocular, can quickly recover vision after operation, and is easy to establish monocular vision and stereoscopic vision.

Intraocular lens implantation is a surgical procedure in which an intraocular lens is implanted into a human eye, in which the lens is removed from the package with clean, dry, toothless wire forceps. The artificial lens is put into a special clamping groove of the folding forceps to be folded. The folded intraocular lens is then grasped by the implantation forceps. The folded intraocular lens is inserted into the anterior chamber with the folded edge to the left, in a manner parallel to the tunnel incision. The angle is adjusted to allow the lower haptics to enter the capsular bag. When the lower loop is confirmed to enter the capsular bag, the implanting forceps are slightly rotated rightwards, the folding edge is rotated upwards, and the implanting forceps are slowly released; after the lens is fully deployed, the forceps are slowly withdrawn. The loop of the crystalline wire is a necessary surgical instrument in intraocular lens implantation and functions to sheath the crystalline nucleus and deliver it. The crystal wire ring in the prior art has the structure of a rear end straight rod and a front end annular sleeve, and the crystal wire ring is not easy to be pulled out because of lack of effective adhesive force when pulling out the crystal core.
