Description
Technical field
The utility model relates to medical instruments fields, and in particular to a kind of ophthalmology silicone oil draw-out device.
Background technique
Silicone oil is widely used in operation on vitreous as Ocular tamponades, easily draws since silicone oil is placed in for a long time in vitreum
Complication, such as cataract, corneal degeneration are played, therefore should be drawn off after reattachment of retina, during taking-up,
It is possible that complication, such as retina is detached from again, expulsive haemorrhage, Ocular hypotension, some of them complication and silicone oil
Removing method and the instrument of application are related, and the common method of silicone oil removal has active method and passive means at present, and active method is to pass through
Silicone oil is actively sucked out for vacuum suction, which need to be connected to glass for trochar and cut on the suction unit of machine, and advantage is when taking silicone oil
Between it is short, but need to cut machine equipped with the glass of suction unit, have silicone oil adherency after taking silicone oil, in casing, not easy cleaning, therefore operate
Complexity, cost is high, and only a small number of large hospitals are being applied in real work, and due to no related equipment, general hospital still applies quilt
Dynamic method makees two notch on sclera, and a notch is perfused, and overflows silicone oil by notch by another, but this method notch too
Hour, silicone oil is not easily taken out, and notch is excessive, Yi Yinqi Ocular hypotension, causes the explosive big bleeding of choroid, and easily cause silicone oil residual
