Good effect of the present utility model is：

(1) eyelashes, margo palpebrae, puncta can be effectively blocked, the interference in surgical procedure is reduced.

(2) it is placed at the fornical conjunctiva of the conjunctival sac of eye, it is to avoid the slip of eye speculum, is effectively increased by inner membrance ring The comfort level of patient, Clinical Compliance is more preferable.

(3) the tubular elastomeric snap ring has good tension force, can retract eyelid, it is to avoid the influence of blinking of eyelid is performed the operation, Exposure cornea and bulbar conjunctiva, are easy to operation technique simultaneously.

(4) the inner membrance ring, outer membrane ring, tubular elastomeric snap ring in closure tubular structure, will not hook strip suture and tissue, keep away Exempt from suture and tissue is brought into the wire, sheet metal, bolt of traditional eye speculum, influence operation technique.

(5) aseptic packaging is used, it is disposable, it is to avoid the generation of cross-infection.

Embodiment

The utility model is described in further detail with reference to the accompanying drawings and detailed description.

As shown in figure 1, a kind of Dispoable medical Blepharostat for use in ophthalmologic operation described in the utility model, including it is integrally formed knot Inner membrance ring (1), outer membrane ring (2), the tubular elastomeric snap ring (3) of structure.

As Figure 2-3：Inner membrance ring (1) external diameter R1 is that 10mm~40mm, internal diameter r1 are that 6mm~32mm, film thickness a are 0.1mm~2mm；Outer membrane ring (2) external diameter R2 be 10mm~80mm, internal diameter r2 be 6mm~32mm, film thickness b be 0.1mm~ 3mm；Tubular elastomeric snap ring (3) internal diameter r3 is that 6mm~32mm, film thickness c are 0.1mm~5mm；Height h is 1mm~20mm.

During production, inner membrance ring (1) thickness and outside dimension are designed according to human physiological structure, with reference to the soft bullet of silicon rubber Property, inner membrance ring (1) is placed at the fornical conjunctiva of the conjunctival sac of eye, it is to avoid the slip of eye speculum, effectively increases relaxing for patient Appropriateness, Clinical Compliance is more preferable.

Outer membrane ring (2) is placed in eyelid surface, can effectively block eyelashes, margo palpebrae, puncta, reduce in surgical procedure Interference.
