Referring to fig. 1, the device for taking silicone oil after retinal repair surgery according to the embodiment of the present invention includes a negative pressure suction apparatus 1, a suction apparatus leather tube 3, a sputum suction tube 5, a needle cylinder 6 and a trocar 7. The negative pressure aspirator comprises a pressure regulator (not shown in the figure) and a liquid collecting bottle 1, wherein a negative pressure terminal interface (not shown in the figure) and a working cavity interface 2 are arranged on the liquid collecting bottle 1. When the negative pressure terminal interface is connected to the negative pressure terminal through the hose, air negative pressure is generated in the liquid collecting bottle 1, and the working cavity interface 2 is communicated to the vitreous cavity of eyes at the moment, so that silicone oil placed in the retinal detachment surgery process is sucked out of the liquid collecting bottle. The liquid collecting bottle 1 is usually made of pressure-resistant transparent polyester plastic, and the pressure regulator can be separately arranged with the liquid collecting bottle and connected through a hose, and can also be integrated with the liquid collecting bottle. The split type negative pressure aspirator with the liquid collecting bottle and the pressure regulator separated is preferably adopted in the embodiment, so that a doctor can more conveniently control the switch of the negative pressure aspirator and adjust the suction force of the negative pressure aspirator during an operation.

The working cavity interface 2 is hermetically connected with a hose 3 made of rubber, and the other end of the hose 3 is connected with a transition joint 4. The hose 3 may be made of silicone. The transition joint comprises a large interface 41, a small interface 42 and a reducing channel 43 communicating the large interface 41 and the small interface 42. The reducing channel is horn-shaped, one end of a large opening of the horn is communicated with the large connector 41, one end of a small opening of the horn is communicated with the small connector 42, and the aperture of the large connector 41 is larger than that of the small connector 41. The inner wall of the reduced diameter channel is provided with a converging groove 431 along the length direction of the channel, the width of the converging groove is gradually reduced from one end of the reduced diameter channel communicated with the large port 41 to one end communicated with the small port 42, and the depth of the converging groove is gradually reduced from one end of the reduced diameter channel communicated with the large port 41 to one end communicated with the small port 42. The small connector 42 of the transition joint 4 is connected with the other end of the hose 3, and the large connector 41 is connected with the syringe 6 through the drainage tube 5. The drainage tube is made of medical high polymer materials or silica gel materials, is sterilized by ethylene oxide, and has good air tightness. The length of the drainage tube 5 is 15-30cm, the outer diameter is 2.5-2.6mm, correspondingly, the inner diameter of the large connector 41 of the transition joint 4 is 2.5-2.6mm, and the inner diameter of the small connector 42 is 1.5-2 mm. Therefore, the negative pressure generated by the negative pressure suction apparatus is buffered by the transition joint 4 and then acts on the vitreous body, and the discomfort of a patient caused by the negative pressure suddenly generated by the negative pressure suction apparatus is reduced. And the sink flow 431 enables the silicone oil to slowly collect in the reduced diameter channel 43 and flow into the drip bottle.

The needle cylinder 6 adopts a specification of 1mm, the front end of the needle cylinder 6 is connected with the trocar 7, the trocar 7 is used for a doctor to operate and puncture the iris, and an iris puncture opening is formed on the iris for the silicon oil to flow out. When the negative pressure suction device is used in specific application, the negative pressure suction device 1, the hose 3, the transition joint 4, the drainage tube 5 and the needle cylinder 6 are connected in sequence, and then the trocar 7 is inserted at the front end of the needle cylinder 6, so that the silicone oil can be taken immediately.

In addition, a non-return flap for preventing suck-back can be arranged in the drainage tube 5 or the hose 2, so that the taken-out silicone oil can be prevented from flowing back to the eyes of the patient.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
