Description
Technical field
The utility model relates to clinical ophthalmology treatment technology fields, specifically, being that a set of ophthalmic cornea metaplax layer removes
Instrument.
Background technique
Cornea can be divided into 5 layers from physiological anatomic architecture: epithelium layer, bowman's lamina, hypothallus, metaplax layer, endothelium
Cellular layer.Penetrating keratoplasty is the method for replacing holostrome muddiness cornea with holostrome transparency cornea, is bored with the trepan of certain diameter
Lesion Full-thickness corneal has been removed, then with same bore or somewhat larger trepan, has drilled through donor's cornea piece, closely with nylon wire
It is sewn on acceptor's cornea.Lamellar keratoplasty is a kind of corneal transplantation of segment thickness, and only excision has the cornea shallow-layer group of lesion
It knits, the more intact acceptor's cornea of deep layer remains as transplant bed, before then taking onesize and thickness donor's cornea
Layer corneal film, is sewn on the surface of a wound of recipient cornea.Lamellar keratoplasty does not penetrate anterior chamber, belongs to an outer operation, does not disturb generally
Eye inner tissue, complication are less.
After Deep liminal keratoplasty, the remaining corneal posterior lamella research of chaotic phenomenon of some patientss meeting is mainly shown as graft
Transparent and remaining self metaplax layer cornea tissue muddiness itself is opaque, to largely affect the view for suffering from eye
Power.Currently, main therapeutic modality is using penetrating keratoplasty.Though this method can improve patient symptom, restore eyesight,
Due to needing to go secondary corneal transplantation, there are corneal donor waste, it is damaging it is big, complication is more, and spend the disadvantages of high.Such as
It can be carried out metaplax layer and remove a kind of more satisfactory processing art formula that will be, the i.e. muddy back plate through anterior chamber's centering CCTV axis area
Layer progress is small-scale to be removed, and to remove muddiness, improves symptom.Because not damaging the corneal endothelium removed other than region, thus it is unlikely
In the decompensation for leading to corneal endothelium function.
Currently, there is no the device that through the diagonal film metaplax layer of anterior chamber can remove operation in micro-surgical instruments clinically
Tool.In addition, inverted plate is separated and removed due to lacking fulcrum, one-handed performance has difficulties, and clinically there is no can through anterior chamber
Play the micro-surgical instruments for assisting reversed fixed function.
Chinese patent application: 201020108597.9, disclose a kind of Descemet membrane dilaceration forceps.It is described to remove tweezer packet
It includes tweezer handle, crank arm, tooth form tweezer head.The end of tweezer handle is connected with the bending to raise upward and cranks arm, and the end cranked arm, which has, to be folded upward at
Tooth form tweezer head.The utility model structure is simple, easy to use, removes since the radian cranked arm is specific to entocornea
And design, facilitate the operation in art, be better than crystalline lens Tweezers for eye surgery, guarantees that operation is gone on smoothly.Suitable in corneal endothelial trans-plantation
Middle use.
Chinese patent application: 201520263143.1, a kind of ophthalmology Tweezers for eye surgery is disclosed, the Tweezers for eye surgery is it is characterized in that packet
Include tweezer handle, tweezer arm and oblique clamp arm.Oblique clamp arm is equipped with clamp platform, can remove visual area by the front end of clamp platform in capsulorhexis
Front cyst membrane, the rear end of clamp platform can easily remove the cyst membrane at visual area rear, keep surgical procedure more perfect, avoid expansion
Operative incision, while while making capsulorhexis, is more accurate in the operation of clamping range blind area.
But above patent document is about can be used in Ophthalimic microsurgery removing descemet's membrane through anterior chamber, and can perform the operation
In anterior chamber can be played assist the technical solution of reversed fixed function be showed no disclosure.
In conclusion needing a set of dedicated corneal posterior lamella removes instrument, corneal posterior lamella can be removed through anterior chamber, and
The reversed fixed function of auxiliary can be played to cornea during surgery, make the remaining muddy disease of corneal posterior lamella after deep lamellar keratoplasty
Example avoids secondary corneal transplantation, while not will lead to corneal endothelium function decompensation removes instrument, and removes device about this
Tool yet there are no report.
Summary of the invention
