Abstract

The invention discloses an artificial lens pushing and injecting device, and relates to an artificial lens implantation surgical operation instrument. Two moving pieces which can be opened and closedare arranged on a folding clamp, an annular groove which fits the folding clamp is formed in the front end of a needle tube, and a push rod is arranged in the needle tube. According to the device, a traditional combined installing manner of the folding clamp and an injector is changed to reduce the risk of the damage of an artificial lens and achieve the dismantling and replacing of the folding clamp, recycling of the injector is further achieved, waste is reduced and the medical cost is reduced, accurate practicing and handling of the injection angle and pushing strength of the injector whenartificial lens injection operation can be performed aiming at an interned doctor or a student of a medical school, the standardized and normalized of artificial lens implantation operation operatingprocedures are achieved, and operation medical risk is greatly reduced.

Description

technical field

[0001] The invention relates to an intraocular lens implantation surgical instrument, in particular to an intraocular lens injection device. Background technique

[0002] It is well known that the intraocular lens is currently the most effective method for correcting the refraction of aphakic eyes. It replaces the original lens anatomically and optically, and constitutes a nearly normal system, especially the one fixed in the normal physiological position of the lens. Posterior chamber intraocular lens. It can be used for one eye, and the visual acuity can be restored quickly after operation, and it is easy to establish binocular monovision and stereopsis. According to the different materials of IOLs, IOLs are divided into hard IOLs formed of hard materials and soft IOLs. Soft IOLs are also called foldable IOLs. When using a rigid IOL, the surgical incision should be at least 6 mm wide at the time of implantation. In contrast, intraocular lenses made of ...
