Description

Capsular capsular incision device {CATARACT CAPSULOTOMY DEVICE}

The present invention relates to an anterior capsular capsular incision device, and more particularly, to an anterior capsular capsular incision device for enabling even a beginner to easily and conveniently incise an anterior capsular capsular caps during cataract surgery.

The eyeball is an organ that secures vision by sensing the strength and weakness of light, and consists of a cornea that refracts light, a lens that acts as a camera lens, an iris that controls the amount of light, and the retina, a transparent neural tissue that corresponds to a camera film. consists of including

Among them, the lens corresponds to a camera lens, and when the lens becomes cloudy, light cannot pass well into the eye and objects may appear blurry. When the lens becomes cloudy and blurry, it is called a cataract.

When such a cataract occurs, the anterior capsular capsule surrounding the lens is incised, the lens located therein is removed, and an artificial lens is inserted.

However, when the anterior capsular capsule is incised, if the incision is too large, the lens nucleus can easily escape forward, making it difficult to fix the intraocular lens. there is.

1 is an exemplary view showing a conventional general anterior capsular incision method.

As shown in FIG. 1 , since the conventional method of incising the anterior capsular capsule relying on the sense of the hand, it was difficult for an unskilled person to cut the anterior capsular capsule in a desired size, particularly in a circular shape.

Recently, a method using a circular cutter has also been used, but the circular cutter has a long after-effects of treatment because it is difficult to insert only a part of the cornea, and since it has to be cut while pressing the lens with a relatively large force downward, damage to the eye may occur. there is a problem.

In addition, there is a method of cutting the lens by generating heat through electricity in the prior art, but there may be a problem in that heat is generated more than necessary and damages the surrounding parts.

Therefore, even beginners can easily incise the anterior capsular capsule in a circular shape, and an economical anterior capsular incision device is required.
