Specific implementation mode
Technical scheme of the present invention is clearly and completely described below in conjunction with attached drawing, it is clear that described implementation
Example is a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill
The every other embodiment that personnel are obtained without making creative work, shall fall within the protection scope of the present invention.
Keratonosus is the second diseases causing blindness in global range, and corneal transplantation is the current treatment the only effective side of corneal blindness
Method.Annual China waits for the patient of corneal transplantation probably to have more than 30 ten thousand, and positive the becoming of rising year by year of presenting of this number
Gesture.Corneal transplantation is the optimal selection of clinical treatment keratonosus, and cornea lamellar blade is used for ophthalmology hand in corneal graft
In art.
It has been investigated that most of cornea lamellar blade is mainly short of a kind of cutting fixing device now, therefore usually cut
It is all to be fixed with human hand, and corneal stroma cutting is an accurate operation to cut operation, and it is easy to appear errors for human hand fixation, thus
Cutting success rate is caused to reduce.And the corneal graft integral thickness of acquisition is inhomogenous, surface irregularity, can influence postoperation recovery.
Raw material are also wasted simultaneously, also add blade usage quantity (blade is expensive), production cost has been significantly greatly increased in this.This
Outside, the tact skill of different doctors and experience difference, finally obtained corneal graft is also not quite similar, simultaneously because processing procedure
The complicated and operating time is longer, be easy to cause corneal graft pollution, to bring risk to operation.
