Abstract
The utility model relates to a cornea marker suitable for a corneal transplantation operation. The cornea marker comprises a circular ring suitable for an eyeball, wherein at least four elastic marker lines are arranged on the circular ring; two ends of the marker lines are respectively fixed on the circular ring; the marker lines cross, and the cross point is in the center of the circular ring; the marker lines adsorb a marking liquid. According to the utility model, the marking liquid adsorbed on the marker lines is utilized to respectively mark colored thin limes on an operated eye and a supplied cornea, a trephine is used to excise the ill cornea of the operated eye to form a transplant bed, a transplant piece is excised from the supplied cornea, and as the marker lines are formed on both the transplant bed and the transplant piece, as long as the marker lines of the transplant bed and the transplant piece are aligned during suturing, accurate apposition suture of the transplant bed and the transplant piece can be realized. The cornea marker can be applied to ophthalmologic operation.
Description
Technical field
This utility model relates to the operating theater instruments of ophthalmology, particularly relates to a kind of cornea marker.
Background technology
Corneal graft is muddy with the displacement of transparent corneal film or has the cornea of lesion portion, with reach increase depending on, treat some keratopathy and improve the object of outward appearance, be the best a kind of operation of heteroplastic transplantation effect.Its operative Principle is according to extent of disease, to select the corneal trephine of suitable bore, makes respectively art eye and for cornea excision, makes transplant bed (art eye) and graft (for eye), and graft is placed on dislocation bed, and suture is fixed.
The key problem in technology of corneal graft is Grafted stitching, and good apposition suture can effectively reduce the irregular astigmatism of cornea, improves Postoperative visual acuity.Current cornea marker, only for cornea excimer laser refractive surgery, due to factors such as diameter are too short, curvature is fixing, cannot be applied to the cornea labelling in corneal graft.And owing to not being specifically designed to the cornea marker of corneal graft, cause the sewing effect of cornea not good, affect postoperative vision.
Utility model content
In order to overcome above-mentioned technical problem, the purpose of this utility model is to provide a kind of cornea marker that is applicable to corneal graft.
The technical scheme that this utility model adopts is:
A kind of cornea marker that is applicable to corneal graft, comprise the annulus that is suitable for eyeball, described annulus is provided with at least two and has elastic mark line, the two ends of described mark line are separately fixed on annulus, described each mark line intersect and intersection point on the center of circle of annulus, described each mark line absorption has marking fluid.
As the further improvement of technique scheme, described each mark line is fixedly connected with at intersection point place.
As the further improvement of technique scheme, described mark line has four, and each mark line is " rice " font and distributes.
As the further improvement of technique scheme, described mark line is made by elastic fiber.
As the further improvement of technique scheme, the excircle of described annulus is provided with for holding the pit of mark line.
Further improvement as technique scheme, is connected to gripping handle on described annulus.
The beneficial effects of the utility model are: the marking fluid that this utility model utilization is attached on mark line is provided coloured fine rule at art eye with for labelling on cornea respectively, use afterwards ring drill excision art eye diseased cornea, become transplant bed, and cut out graft from supply eye, owing to all there being mark line on transplant bed and graft, while therefore sewing up, both mark line alignment can be realized to both accurate apposition sutures.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of cornea marker that is applicable to corneal graft, comprises the annulus 1 that is suitable for eyeball, and the diameter of this annulus 1 can be 11～13mm according to the eyeball size of different crowd.Annulus 1 is provided with at least two and has elastic mark line 2, and the two ends of every mark line 2 are separately fixed on annulus 1, and each mark line 2 intersects crossing intersection point is overlapped with the center of circle of annulus 1.In use, on each mark line 2, absorption has marking fluid, therefore utilizes the marker in the present embodiment to mark fine rule at the anterior corneal surface that is spheric, to facilitate transplant bed and Grafted apposition suture.
Preferably, each mark line 2 can utilize the variety of ways such as viscose glue to achieve a fixed connection at intersection point place, has guaranteed each mark line 2 each other and the location of cornea central authorities, is not easy to occur skew.
Preferably, mark line 2 has four and be " rice " font and distribute, and makes apposition suture point have 8, with in conventional art 0 °, 90 °, 180 ° compare with 4 apposition suture points of 270 °, can obtain para-position effect more accurately.
Preferably, mark line 2 adopts elastic fibers to make, and has guaranteed enough thin of enough elasticity and mark line 2, and is difficult for corneal and causes damage.
Preferably, the excircle of annulus 1 is provided with for holding the pit 3 of mark line 2, and the size of this pit 3 is advisable just to hold mark line 2, can not be moved at circumferencial direction after making mark line 2 enter pit 3.
Preferably, on annulus 1, be connected to gripping handle 4, facilitate doctor to execute art.
Utilize marker in the present embodiment to carry out the process of cornea labelling as follows: first on mark line 2, to adhere to the coloured marking fluid of tool, annulus 1 is enclosed within to eyeball surface, utilize the marking fluid on mark line 2 at art eye with for labelling on cornea, to provide coloured fine rule respectively, use afterwards ring drill excision art eye diseased cornea, make it to become transplant bed, and cut out graft from supply eye, graft is positioned on transplant bed, owing to all there being colored labelling lines on transplant bed and graft, while therefore sewing up, both labelling lines alignment can be realized to both accurate apposition sutures.
The above be this utility model preferred embodiment, it does not form the restriction to this utility model protection domain.
