Silicone oil taking-out sealing ring for ophthalmology department

Abstract

The invention relates to a silicone oil taking-out sealing ring for the ophthalmology department. The silicone oil taking-out sealing ring for the ophthalmology department comprises a silica gel ring and a polyethylene baffle. The silica gel ring is a hollow cylindrical elastic ring, and an annular groove is formed in the lower portion of the silica gel ring. The polyethylene baffle plate comprises an inner ring and a baffle plate; the inner ring is arranged in the annular groove below the silica gel ring, and the outer diameter of the inner ring is equal to that of the silica gel ring; the baffle plate is fan-shaped and comprises a horizontal baffle plate and an outer baffle plate; the baffles are symmetrically distributed about the circle center of the inner ring, and the central angle is 90 degrees; a groove is defined by the horizontal baffle, the outer baffle and the silica gel ring on the inner side and used for containing a suction tube; and the silicone oil taking-out sealing ring for the ophthalmology department further comprises a sleeve matched with the silicone oil taking-out sealing ring for the ophthalmology department. The ilicone oil taking-out sealing ring has the advantages that the problems of local conjunctival congestion and bleeding in the existing silicone oil extraction operation can be effectively solved, eyeball tissues are protected, one-time complete suction can be realized, the operation time is shortened, and the silicone oil extraction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an ophthalmic silicone oil removal sealing ring. Background technique [0002] In order to prevent the occurrence of postoperative retinal detachment or re-detachment, after vitreoretinal surgery such as complex retinal detachment, proliferative diabetic retinopathy, retinotomy and resection, it is necessary to routinely perform intraocular silicone oil filling. According to the condition, the silicone oil removal operation will be performed 3-6 months after the operation. [0003] Silicone oil plays an important role in the treatment of complex retinal detachment due to its unique physical properties. However, silicone oil cannot be absorbed by intraocular tissues, and long-term indwelling in the eye can easily cause serious complications, such as cataracts, glaucoma, low intraocular pressure, and corneal endothelial lesions Therefore, it is very necessary to perform si...
