[0002] In the current retinal detachment treatment method, a common operation is to inject silicone oil into the patient's eye to support the reattachment of the retina, and after the patient's retina is completely recovered, the silicone oil in their eyes will be removed. According to the search, the patent with the patent number CN214858185U discloses an intraocular silicone oil extractor. When the device is used, the elastic member can provide a rebound force to enable the piston rod to quickly recover, making the extraction process effortless and improving the extraction efficiency. However, the traditional silicone oil is extracted by applying negative pressure to the needle through a sleeve (or directly connecting a syringe), which usually requires two or more people to operate, at least one of whom needs to maintain negative pressure. Because the negative pressure cannot be too high, excessive negative pressure can harm other tissues in the eye. If the extraction pressure is stopped, the negative pressure will flow back, causing the negative pressure to be too low and the suction force to be insufficient, making it difficult to extract all the silicone oil.
