Abstract
Set of devices mechanically linked to one another by a single set (01) that has the possibility of facilitating the lamella surgeries performed by ophthalmological surgeons without the need of removal from the eye at any time during the surgery, having control of the vacuum (13), leveling (02) and thickness of the cut (02 and 04) performed manually or automatically. This combination, non conventional, of the model presented here which is not conventional and adjusted technically, makes us believe that it is a sui generis Patent.

Descriptive Report of the Patent of the "APPROPRIATE EQUIPMENT TO CORRECT AMETROPIA AND
PERFO~M LAMELLA TRANSPLANTS" Utility Model.
This Patent refers to the "APPROPRIATE
s EQUIPMENT TO CORRECT AMETROP] A AND PERFORM
LAMELLA TRANSPLANTS" studied in its minimal details, so that it can outstand other similar products.
As it is knowledge of the specialized medical class that this equipment works as follow: the larnination process is done 10 by a micro plane called microceratomo that is driven automatically and manually after placing the rings and levelers to make the cut of the disc.
This process does not enable the surgeon to see the cut during the surgery, i.e., he does it blindly as he cannot see what he does.
With.the existing equipments the professional is obliged to change the levelers durillg the surgery. Such procedure is uncomfortable to him and to tlle patient as well.
With other equipments the set moves completely to make the lamella cut.
In some equipments there are several suction rings with variable height and in others the suction ring is adjustable for the placement of the levelers.
The suction ring purposes are: to fix the eye, project the cornea for leveling and lamella cut.
When perforrning the larnella cut it is necessary to put the microplane known as microceratomo, in the prism of the ring that causes a lot of difficulties to the surgeon.
This way, the frequent change of the suction rings, together with the levelers, expose the eyeball to a greater time of ~6~
suction that can cause damage due to th=e- increase of the inter-ocular pressure up to 180 seconds per application.
The blade, basically, helps accomplishing the cornea cut.
The existing ones have rectangular and circular shape.
The rectang~llar ones are stressed in size, weight and thickness of ovel- 20() micro that causes impert`ect corlleas cut.
Due to this shape and to the friction of the blade o with the microplane, it causes mechanical abrasion, releasing metal particles that will settle in the interface between the disc and the receptor cornea's stroma.
The placement of these blades is done through the particular blade supporter in its central part with about 3 0 micro of S looseness that can cause variations in the cut.
The circular ones always move rotatorly in the same direction that can damage the lamella cut.
In some existing kinds of equipment the vacuum is used in separated sets of microceratomo that obli~es the professional to use both hands during the surgery.
In other equipltlents the vncuulll wolks about ''~
inches of mercury, theref`c)re, e~;cessively incl easillg the inter-oc~lla pressure during the surgery.
In such case, the result of using the existing equipment causes the following basic problems: '~change of levelers during the surgery" and "no surgcry transparency" as the sulgeon cannot see what he does.
Therefore, analyzing these problems the inventors created and developed through many experiments and lab tests a new concept of appropriate equipment to correct Ametropias and perform Lamella Transplants.
This patent is made of new elements that are safer and easier to be assembled as you can see as follow.
The LEVELER VIEW FTNDER Ol PLAIN
BLADE(02), object of this model, is placed in to centralize it having plai 321~52~ .
lens without graduation to make the corneas leveling which will determine the diameter of the cornea's disc to be cut.
The LEVELER VIEW FINDER or PLAIN
BLADE(02), object of this model, has XY Axes Setting (02) to a colrect 5Visual Axis Determination.
The LEVELER VIEW FINDER (02) has also a Diameter Setting (02), varying from 4 to 10 mm, with a break of 1 mm.
Thc LEVELER VIEW FINDER (02), workillg as a Fixed Platt`orm (0~) can show in its lowel palt convexity or concaveness 10with the purpose of withdrawing the l.enticle as a di~ergent or con~ergent.
The LEVELER VTEW FINDER (02), working as a Fixed Platform (02) and can also show in its lower part a Pl e-Programmed Table to correct regular and irregulal astigmatisms.
l his disc COI l esponds to the back part of the 15cornea from the epithelium, Bowman membrane and the back part of the stroma.
Besides the above mentioned function the Leveler View Finder (02) works like a fixed support platform, placed horizontally at the cornea.
20TllerefOre, ill this patent, the FIXED VIEW
FINDER (02) means a worry !ess to the professional during the surgery.
The Leveler View Finder (02) controls the lamella's leveling diameter to be cut in its vertical movement.
The equipment has a parlicular feature: it has only 25one vacuum suction ring (03) which does not need any change, adjustment nor removal from the eye during the surgery.
An about 100 micro thick 420 stainless steel blade (04) is used according to the surgical specifications, 2 mm wide and 16.5 mm long and micro-sharpened having an oscillatory movement and 30fixed to the blade support.
The BLADE SUPPORT (05) is used with 2 (two) equidistant pressure supporters to fix the blade (04) performing the traction and its placing.
The BLAOE POSITIONER ~06), a device used to place the blades, is characterized by carlying out counler-pressule at the 2~
stems of the support of the blades (04), thus simplit`~illg its perfect placing and removal. ~ ' l''he calibratio!~ o'f the Thickness (08) will be determined by the Micrometric Button (0g) that regulates the distance of s the Blade (04) in the Transparent Fixed Platform (02).
The MAIN BED GUIDE BUTTON (11 ) is a device responsible for moving the Main Bed (09) together v~ith the Blade (04) to perform the ceratectomy.
This movement can be manual or automatic by o using a Nut Blank (06), Idler Pinion (07) and an Endless Thread (16).
The MAIN BED MOVEMENT SHOCK-ABSORBER (12) is a device that has the purpose of controlling the "~oes and comes" speed of the Main Bed as well ;ls cusl~ionillg the movemcnts.
l'he equipmellt is drivell by a l~ V DC single s micro-motor or AC transformer or Piezoelectric Crystal.
The MAIN BED (09) is a set that has the function of defining the adjustment of the Leveler View Finder (02), the Blade ~leight and the "goes and comes" movement of the Blade Support.
The VACWM TUBE (13) is a device that has a silicon hose coupled to a vacuum that produces suction to the eyeball~ of 15 inches of mercury (Hg) with the purpose of fixing the eyeball without increasing the inter-ocular pressure exceedingly.
This device works coupled to the Cable of the Motor Bearer (15).
The VERTICAL REGI)LATOR BUTTON (18) OF THE LEVER VIEW l;INDER (02) is a device that has the purpose of regulating the diameter of the lamella to be cut.
The Blade Support ~05), The Blade (04), the Leveler View Finder (02) and the Suction Ring (03) can be in only one disposable set (02,03,04 and 05).
Therefore, this present patent that now claims for homologation has the purpose of solving, or furthermore extinguishing all the problems that have remained unsolved for many years so far.
The materials used in this patent are all sel~
cleavable: stainless steel, anodized aluminum, tubes, silicon hoses, electrical cords resistant to high temperatures.
