Abstract

Simulator for the teaching and realization of capsulorhexis for phacoemulsification, the simulator itself consists of a lid with two strips, one upper and one below the lid, which will allow us to tighten the material on which to practice the capsulorhexis. In front of the lid that is on the lower face of the simulator, an opening is placed whereby a sheet of plastic material emerges in which slits similar to the incisions that are made in the real eye for phacoemulsification are made.

Description

Simulator for teaching capsulorhexis for phacoemulsification.

The present invention lies in a simulator for teaching and performing capsulorhexis for phacoemulsification, which in turn presents easy manufacturing and use.

The term cataract refers to the lens opacification, generally transparent lens that it is inside the eye, located behind the pupil and suspended in place by fragile fibrils called zonula. its function is to focus the exterior light on the retina, to be able to see clearly.

Currently, except in case of cataracts secondary caused by systemic diseases or due to a Toxic agent, the only treatment of cataract is surgery. Phacoemulsification is the most modern technique in surgery of waterfall.

One of the critical steps in the development of the Phacoemulsification is the performance of capsulotomy, that is, the technique to break the anterior capsule of the lens.

Although there are different techniques for perform it, the most widespread is continuous circular capsulotomy or capsulorhexis (CCC), described in 1990 by Gimbel and Neuham.

The CCC is a procedure that is done by hand raised, so it requires prior learning, since during the realization of it problems may arise Important and potentially serious. Eye surgery requires great precision and eye-hand coordination in a very small space that can and should be developed with the practice. There is no doubt that for both ethical and legal reasons and otherwise learning any surgical technique does not must be performed on a patient, but previously exercised on models suitable for this purpose.

Given the above, it is intended develop a simulator that serves as a model in which to practice the realization of the CCC, so that it is a training system comprehensive, reproducible and useful for teaching.

The creation of this simulator presents the advantage of allowing the realization and learning of the technique without need to use animals for experimentation or pieces of corpse, as well as the use in any place (being easily transportable).

The cataract models used in the bibliography for learning and practicing these techniques are eyes of rabbit, pig, human corpse and even artificial eyes and 3D image simulators.

The advantages of the present invention they are essentially and merely enunciative and not limiting the following;

-

Easy manufacturing.

-

Easy storage.

-

Scarce weight and measurements.

-

Convenience of use and transport.

-

Simplicity and efficiency of use.

The attached design sheet accompanies a scheme of the invention to allow its better understanding, being this scheme a realizing and non-limiting example of the invention.

The simulator (1) for the realization of the CCC It consists of a part in which the learning of the CCC, where on commercial foil (7) or other commercial similar characteristics we can perform the technique of capsulorhexis All this is inserted in a support of methacrylate (2) to improve the support of the surgeon's hands and prevent the mobility of the simulator on the surgical table.

The simulator will be made of methacrylate. The zone closest to the student (3) has a downward inclination to allow adequate hand support in order to avoid the tremor of tiredness.

It consists of a bottom composed of base (4) and side partitions that serve as support for the simulator, and a upper part (5) which is the simulator itself and that It consists of a lid with two strips (6), one upper and one by under the cover, which will allow us to tension the material (7) on the one who practice capsulorhexis. In front of the cover that is a groove is placed on the underside of the simulator, (8) by the which leaves a sheet of plastic material (7) in which they are made slits similar to the incisions that are made in the real eye for phacoemulsification, in order to perform the CCC, and through which the student will pass the cystitome (a modified needle for the incision in the anterior lens capsule) and the clamp Rexis (a modified clamp to perform this technique). Versus these slots and in the upper portion of the simulator there are 5 studs fixed (9) imitating the lens.

The foil will be stretched between the two strips (6) which will make the five heads of tacks (9) stand out on it, simulating the capsule above, which allows using the cystitome to make a small incision on the tack proceed to the completion of the CCC

Above the tacks (9) there are fixed on the base (4) at least two cylindrical tanks (10) where They place the organs.

Claims (1)

1. Simulator for teaching and conducting capsulorhexis for phacoemulsification preferably performed in methacrylate consisting of a support in whose perimeter they place four lateral partitions and on them a cover with two strips, one upper and one below the lid. In front of the cover that is on the underside of the simulator is placed a opening through which a sheet of plastic material comes out in which similar slits are made to the incisions that are performed in the real eye for phacoemulsification. In front of these slots and in the upper portion of the simulator there are five tacks fixed Above tacks there are fixed on the base at least two cylindrical deposits where the organs The part of the cover closest to the student is placed in oblique descending position.
