| titleOfInvention | Self-closing structure of cannula trocar in vitrectomy |
| abstract | The utility model provides a self-closing structure of a cannula trocar in a vitrectomy operation, which relates to the technical field of medical devices, and solves the problem that a channel established by a cannula in the prior art has no self-closing function, and it is easy to cause fluid in the eye or technical problems with gas loss. The device comprises a self-closing valve and a puncture needle, wherein the puncture needle can be inserted into the self-closing valve and the self-closing valve can be inserted into the vitreous cavity under the pushing of the puncture needle; the self-closing valve can be inserted into the vitreous cavity; The closing valve includes a self-closing section, the material used for the self-closing section is silica gel, and the self-closing section can expand outward under the action of the puncture system to make the self-closing section conduct; When going out of the self-closing section, the self-closing section can be retracted inward to block the self-closing section. |
