Description

Intraocular lens cartridge receiver for intraocular lens injector {PRELOADED IOL INJECTOR}

The present invention relates to an intraocular lens cartridge receiver for an intraocular lens injector, and more particularly, to an intraocular lens cartridge receiver for accommodating intraocular lens and an intraocular lens cartridge receiver for accommodating and storing the intraocular lens. .

In general, cataracts are caused by clouding of the lens in the eye and, in severe cases, may cause blindness.

Cataracts are classified into hereditary or congenital cataracts that occur at birth, senile cataracts that develop with age, and generalized cataracts that occur when there are various diseases throughout the body.

As a method for treating such cataracts, drug therapy and surgery have been used, but drug therapy is mainly used because there is no guarantee that the cataract can be completely cured.

In addition, the cataract surgery method includes an intracapsular extraction method for removing all of the lens including a bag surrounding the lens, and a posterior portion of the lens, having a thickness of 0.01 mm close to the vitreous body, and removing the remaining lens part, followed by inserting an intraocular lens. There is an extraction method.

Here, the intraocular lens is an artificial lens used to replace the natural lens of the eye when you have cataracts or other diseases, the lens may be inserted into the eye to correct the refractive error of the eye.

An intraocular lens that performs this role is made of various materials or combinations of materials such as PMMA, silicone, hydrogel and silicone hydrogel.

In order to implant the intraocular lens as described above, the sclera of the eye is incised and a viscoelastic material is injected to protect the anterior tissue, and then the upper part of the capsular bag is removed to remove the cloudy lens.

Next, when the upper part of the capsular bag is excised, the clouded lens nucleus is removed from the capsular bag and the intraocular lens is injected into the capsular bag while injecting a viscoelastic material into the capsular bag to facilitate the insertion of the intraocular lens.

Here, the intraocular lens is injected into the capsular bag or in a dried state and then returned to its original state, where an injector capable of injecting the intraocular lens is used.

However, since the conventional intraocular lens cartridge and the intraocular lens injector are separately stored and stored, there is a hassle for an operator to check the inventory and consumption of parts.

In addition, the use of an intraocular lens and intraocular lens injector had to be prepared separately, there was a hassle of work.

The present invention has been made to solve the above problems, and an object of the present invention is to be able to receive and store the intraocular lens cartridge and the intraocular lens injector at one time.

In addition, an intraocular lens cartridge receiver for an intraocular lens injector is divided into a front case and a rear case so that it is easy to combine and replace only the corresponding parts when damaged.

In order to achieve the above object, an intraocular lens cartridge receiver for an intraocular lens injector is formed with a protruding outer wall along the front and rear and outer circumference, and the coupling portion formed at the front and rear ends of the outer wall is stepped. It is formed, the fixed support portion is formed vertically formed with a communication hole through which the intraocular lens cartridge discharge portion is passed around the inner surface, the outer case is formed on the front outer wall and the outer wall is formed along the periphery of the front and rear, The front and rear outer walls are formed with a protrusion formed in the engaging projection coupled to the coupling groove, the outer surface is formed around the outer wall vertically, the inner can support the intraocular lens cartridge wing formed by a rear case formed wing support When the front case and the rear case are combined, it is composed integrally while accommodating the intraocular lens It characterized in that one to be competent.

According to the present invention, it is possible to store and store the intraocular lens cartridge and the intraocular lens injector that accommodate the intraocular lens at once, as well as to reduce the storage space.

In addition, the intraocular lens cartridge receiver for an intraocular lens injector is divided into a front case and a rear case to facilitate the combination, and there is an effect of replacing only the corresponding parts when damaged.

In addition, the lens and the intraocular lens injector can be separated and stored separately when not received, as well as can be easily combined and reused.
