Description
Technical field
The present invention relates to a kind of apparatus that piece materials are planted for donor's cornea, belong to eye surgery technique with the apparatus in medical science
Field.
Background technology
According to the applicant understood, it is existing to donor（Donor）The materials of cornea, are entered by hand by tweezers, blade and scissors
Capable, have the disadvantage that：
1) donor can not quickly be cut（Donor）Cornea, it is impossible to move operation plant for subsequent corneal and win more times；
2) conventional method prepare donor material edge it is irregular, such as need in operation using artificial anterior chamber when be likely to result in confession
Body material cannot be fixed well；
3) traditional materials process is slower, the stand-by period of donor family members when increased materials；Remained after traditional shearing method materials
Sclera incisxal edge is irregular, it is impossible to unfavorable so that the eye of donor still keeps preferable outward appearance after materials, it has not been convenient to remains lift face
In mitigation family members' sad mood.
The content of the invention
The technical problem to be solved in the present invention is, in view of the shortcomings of the prior art, proposing a kind of quickly and easily directly to contributing
Contributor eye in cornea drawn materials and after materials keep the preferable outward appearance of donor's eye for donor's cornea plant piece materials
Apparatus.
The present invention is that the technical scheme for solving above-mentioned technical problem proposition is：A kind of device that piece materials are planted for donor's cornea
Tool, including attract the aspirator of ring, cornea adsorption tube, sclera adsorption tube and cornea adsorption tube and sclera adsorption tube outlet
And blade；The attraction ring is by located at the cornea ring portion on top, the cutting part located at middle part and the sclera ring portion located at bottom
Be connected to each other the attraction ring being made into integration, and is formed respectively with the cornea ring portion and sclera ring portion and cornea surface curvature phase
Divide in the first surface of matching and the second curved surface matched with eyeball scleral surface curvature, the cornea ring portion and sclera ring portion
The annular hollow being connected with cornea adsorption tube and sclera adsorption tube import is not formed with, and it is equal that the cornea ring portion is formed with least two
First opening of the cloth on first surface and for connecting annular hollow to adsorb cornea, the sclera ring portion is formed with least two
The second opening on the second curved surface and for connecting annular hollow to adsorb sclera is distributed on, the cutting part is formed with around attraction
Multi-turn fluting inside and outside the border of ring ring body one and insertion attraction ring, the blade is used to carry out and carry out cornea along a circle fluting to cut
Take.
The present invention is that directly donor's cornea is drawn materials, and during materials, the present invention is pressed on into donor（Donor）
On eyeball, suction is carried out by the aspirator corneal adsorption tube such as syringe and sclera adsorption tube and produces negative pressure so that cornea ring portion is consolidated
It is scheduled on cornea, sclera ring portion is fixed on eyeball sclera, then carries out and carry out cornea along a circle fluting using blade
Cut, it can be ensured that eyeball is fixed during cutting, deformation is small, beneficial to cutting.Summarize the beneficial effect of the technical scheme of the invention described above
It is really：
1）Because cornea ring portion is formed with least two the first openings for being distributed on first surface, it is equal that sclera ring portion is formed with least two
Second opening of the cloth on the second curved surface, can form uniform negative pressure, respectively immobilizing corneal and sclera, thus keep cornea and
The negative pressure of sclera fixes strength symmetrically, and so, blade is not susceptible to the displacement or deformation of eyeball when being cut；
2）Because cutting part is formed with around the multi-turn fluting attracted inside and outside the border of ring ring body one and insertion attraction ring, blade is along a circle
Fluting is carried out and carries out cornea cutting, it is ensured that blade smooth sliding, the corneal graft incisxal edge rule produced in a certain direction
It is whole；
3）Because cutting part is formed with multi-turn fluting, therefore the corneal graft containing different size sclera can be made, it is convenient in operation
Fixed during using artificial anterior chamber and plant piece.
To sum up, the present invention quickly and easily can directly be drawn materials to cornea in donor's eye and keep contributing after materials
The preferable outward appearance of contributor's eye.
The improvement of above-mentioned technical proposal is：The outlet of the cornea adsorption tube and sclera adsorption tube is connected and shape with aspirator
Into a Y-shaped structure.
One of change of above-mentioned technical proposal is：The apparatus also includes located at attraction ring ring body outside and is fixed on corneal ring
Handle in portion and sclera ring portion, the handle is inclined upwardly, the cornea adsorption tube and sclera adsorption tube both pass through handle and
Fixed by handle.
The improvement of one of the change of above-mentioned technical proposal is：The handle is provided with anti-slip veins.
The two of the change of above-mentioned technical proposal are：It is described to attract the attraction ring that ring is annular.
