Description

Injector for inserting lens into eye after cataract procedure {A METHOD AND APPARATUS FOR FOLDING A DEFORMABLE INTRAOCULAR LENS}

In the present invention, when inserting or injecting the lens into the eye after the cataract procedure, the lens is mounted on the disposable cartridge and then seated in the eye using a screw and a push rod, the screw is turned in accordance with the doctor's choice within the body The present invention relates to an injector for inserting a lens into the eye after a cataract procedure, which is configured to be injected in a rotational manner, or to be injected in a pressing rotational manner to provide a simple and easy procedure for the operator.

In general, the lens within the eye has been widely used in place of the human lens after cataract removal surgery.

Thus, the lens is generally recognized as a transparent structure having a thickness of about 5 millimeters and a diameter of about 9 millimeters. At this time, the lens is hanging behind the iris by a platoon fiber connecting the lens to the ciliary body.

This lens is surrounded by a capsular bag, the front part of which is generally known as the frontal sac and the back part is known as the posterior sac.

On the other hand, many procedures have been developed for the removal of cataracts, and these procedures are formed to remove the lens from the eye and replace it by implanting the intraocular lens.

However, in the past, skilled doctors were generally formed to pinch a lens made of a material such as glass or plastic suitable for use in the eye with a tweezer or the like to settle in the eye. Frequent safety accidents have occurred.

In recent years, a separate injector has been devised and used, but such a conventional design is formed only by a syringe-type push injector or a screw-rotating injector, which requires the operator to select a product suitable for him. Troublesome problem is occurring.

The present invention is to solve the above-mentioned problems, the technical gist of the lens into the eye after insertion or injection, after the cataract procedure, the lens is mounted on the disposable cartridge and then mounted in the eye using a screw and push rod, The screw is injected in a rotational rotation method or a push rotation method in accordance with the doctor's selection in the main body is to provide a simple and easy operation convenience for the operator.

An injector for inserting a lens into the eye after a cataract procedure, characterized in that the procedure to select any one of the injection method.

[Example]

First, using the handle of the cartridge, the hinge opens the mount and seats the lens to be mounted in the hemispherical feed hole.

At this time, the lens is formed to be folded in half when the circumferential surface end is inserted into the guide groove to close the mounting portion.

This is to allow the discharge port to easily discharge the lens through the discharge hole.

At this time, the lens-mounted cartridge is introduced into the inner space through the detachable groove of the main body, and the cartridge is in close contact with one side of the detachable groove so that the discharge hole of the cartridge branches to the outside of the opening hole of the main body.

At this time, the holder and the screw guide is coupled to the coupling hole side of the main body in order, the holder is to support the screw guide, the screw guide is formed so that the fixing projection is coupled to the fitting hole of the main body while supporting the holder.

Thereafter, the push rod is introduced through the coupling hole, and behind it, the screw is engaged to push the push rod like a piston of a syringe.

In this case, a push protrusion is formed at the front end of the rod of the push rod, and a silicon rubber is provided at the front of the push protrusion to prevent the lens from being damaged (scratch, tearing, etc.).

Then, the operator puts a finger on the support of the main body and pushes or pushes the push rod toward the opening hole by rotating or pushing the screw by using a rotating rotator or cap of the screw to rotate the female thread and the male thread of the screw. As a result, the lens is pushed out of the discharge hole of the cartridge.

At this time, the pitch spacing of the female thread and the male thread of the main body and the screw is preferably formed about 10 ~ 15mm, this is to facilitate the rotation during the injection feed by the push type.

The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims. Of course, such changes will fall within the scope of the claims.
